Description

电外科计数器及闭锁机构 Electrosurgical counter and latching mechanism

技术领域 FIELD

本发明涉及电外科器械。 The present invention relates to an electrosurgical instrument. 特别地,本发明涉及一种计数器和闭锁设备,该设备与电外科器械一起使用以向使用者指示电外科器械已经经历过的消毒/使用循环的次数,并且一旦进行了预定次数的消毒/使用循环,该设备阻止使用所述电外科器械。 In particular, the present invention relates to a locking device and a counter, used to indicate to a user of the electrosurgical instrument has undergone sterilization times / cycles using the apparatus together with the electrosurgical instrument, and a predetermined number of times Once disinfection / use cycle, the device prevents the use of the electrosurgical instrument.

背景技术 Background technique

在现代外科中,由于电外科仪器和器械的多种功能,电外科技术是一种重要的手段。 In modern surgery, surgical instruments since the electric variety of functions and instruments, electrosurgical technology is an important tool. 许多电外科仪器和器械都是可以再利用的。 Many electrosurgical instruments and equipment are reusable. 可再利用的电外科仪器及器械在电外科手术之后经过消毒,以确保仪器是清洁和无毒的而可用于以后的手术。 Reusable electrosurgical instruments and electrical instruments sterilized after surgery to ensure that the instrument is clean and non-toxic and can be used after surgery. 消毒过程是昂贵的,还会导致可再利用的电外科仪器及器械的磨损。 Disinfection process is expensive, but also lead to wear reusable electrosurgical instruments and devices. 在许多消毒过程中使用热来杀死微生物、细菌、以及其它在电外科仪器的随后应用中可能出现的可能感染源。 In many thermal disinfection process to kill microbes, bacteria, and other surgical instruments in the subsequent application of electricity may be the source of infection may occur. 如同其它的消毒形式,在这些过程中使用的热会损耗可再利用的电外科仪器及器械。 As with other forms of sterilization, the heat used in these processes cause depletion of electrosurgical instruments and reusable instruments. 因此,可再利用的仪器及器械必须设计成可以经受必要的消毒过程。 Accordingly, reusable instruments and equipment must be designed to withstand the necessary sterilization process.

虽然用后可丢弃的电外科仪器和器械可能并不是特别地设计成可以承受许多次的消毒及使用循环,然而,在必须被丢弃之前,这些仪器可以经受有限次数的消毒及使用循环。 Although the use of disposable instruments, and electrosurgical instrument may not be specifically designed to withstand many times of use and sterilization cycles, however, before it must be discarded, these instruments can be subjected to sterilization and use of a limited number of cycles. 由此,一些电外科仪器已经被认为可以重复使用预定次数的消毒/使用循环。 Thus, some of the electrosurgical instrument that have been sterilized can be repeated a predetermined number of times of use / use cycle. 与这些有限重复使用仪器相关的一个问题是:监测一个特定的工具或者器械已经经过的消毒/使用循环的次数可能是很困难的。 One problem associated with these instruments is limited re-use: monitoring a specific tool or instrument has been subjected to sterilization / use cycle times can be very difficult. 因此,仪器或者器械可能在完成预定的使用次数之前就被丢弃掉了。 Thus, the instrument or instruments may be used prior to completion of a predetermined number of times it was dropped out. 还可能发生的是:由于医生的疏忽,电外科仪器或者器械的使用次数可能大于预定的使用次数。 It may also happen: Because the doctor's negligence, the frequency of use of the electrosurgical instrument or the instrument may be greater than a predetermined number of uses.

开发了多种机构及系统,用于监测电外科仪器或者器械所经历过的消毒/使用循环的次数,以试图防止过少或者过多地使用所述有限重复使用的电外科仪器或者器械。 We developed a variety of systems and means for monitoring the number of times the electrosurgical instrument or instrument experienced sterilization / use cycle, in an attempt to prevent too little or too much electrosurgical instrument or instruments using the limited reusable. 一个用于监测消毒/使用循环的次数的示例系统采用了一种温度响应元件,其对应于消毒循环而增加或者减小计数器的计数。 A number of exemplary system monitor sterilization / use cycle for using a temperature responsive element, which corresponds to the sterilization cycle and increasing or decreasing the count of the counter. 然而,消毒循环进行的方式使得这种温度响应机构是不精确的或者完全是无效的。 However, such a manner that the sterilization cycle the temperature responsive means is inaccurate or totally ineffective. 原因在于:消毒过程采用了加热和冷却循环,其中在单次消毒过程中,电外科仪器经历了多个温度的峰值和谷值。 The reason is that: the sterilization process using the heating and cooling cycles, wherein in a single sterilization process, the electrosurgical instrument experienced peaks and valleys of a plurality of temperature. 这会导致在单次消毒过程中温度响应元件多次致动。 This causes the temperature responsive actuating member a plurality of times during a single sterilization process. 由此,在单次消毒循环中,计数器的计数可能会多次地增加/减小,使得不能准确地表示电外科器械实际上经历过的消毒/使用循环次数。 Thus, in a single sterilization cycle, the counter may be repeatedly increased / decreased, making it impossible to accurately represent the electrosurgical instrument actually experienced sterilization / use cycles. 一个另外的复杂因素是:多种类型及设置的消毒过程所使用的循环持续时间是差别很大的,使得设计对于每次消毒过程致动一次的消毒响应机构是困难的。 An additional complicating factor is: cycle duration of the sterilization process and the various types of settings to be used is very different, so that the mechanism is difficult to design for each actuation of a sterilization process sterilizing response.

具体实施方式 Detailed ways

本发明涉及一种具有计数器/闭锁机构的电外科器械。 The present invention relates to an electrosurgical instrument having a counter / lockout mechanism. 本发明的电外科计数器/闭锁机构设计成执行两个主要功能。 The electrosurgical counter invention / latching mechanism is designed to perform two major functions. 首先,其执行一个计数功能,以记录电外科器械已经经历的消毒/使用循环的次数、并且为使用者显示所经历的消毒/使用循环的次数、以及/或者剩余的消毒/使用循环的次数。 First, it performs a counting function to record the number of times the electrosurgical instrument has been subjected to sterilization / use cycle, and the number of times experienced by the user display sterilization / use cycle, and / or residual disinfecting / use cycle. 其次,一旦电外科器械已经经历了预定次数的消毒/使用循环,则计数器/闭锁机构执行闭锁功能,从而防止在任意的其它电外科过程中使用所述的电外科器械。 Second, once the electrosurgical instrument has undergone the predetermined number of sterilization / use cycle, the counter / latch mechanism perform locking function, thereby preventing the use of other electrosurgical procedures in any of the electrosurgical instrument.

依据本发明的一个方面,计数器/闭锁机构包括指示器,用于显示在应当把电外科器械丢掉之前剩余的消毒/使用循环的次数。 According to one aspect of the invention, the counter / lockout mechanism includes an indicator, the number of times before it should be discarded remaining electrosurgical instrument sterilization / use cycle for displaying. 该指示器采用温度致动元件以及机械致动元件(例如机械撞杆)来增加/减小计数。 The actuating element using a temperature indicator and the mechanical actuating element (such as a mechanical ram) to increase / decrease counter. 温度致动元件响应于各经历过的消毒循环而被致动,而机械致动元件响应于各执行过的使用循环而被致动。 The temperature of the actuating element in response to each of the sterilization cycle experienced is actuated, the actuating element is mechanically performed in response to each cycle of use is actuated. 通过结合地使用温度致动元件以及机械致动元件,消除了在单个的消毒/使用过程中计数器计数的多次增加/减小。 By combining the temperature and the mechanical actuating device actuating element, eliminating the single disinfecting / counter during use multiple increase / decrease.

依据本发明的一个方面,一个致动器与温度致动元件以及机械致动元件一起使用而增加/减小指示器。 According to one aspect of the present invention, a temperature of the actuator and the actuating element and the mechanical actuating element for use with the increase / decrease indicator. 在该实施方式中,在消毒循环中,温度致动元件沿第一方向移动致动器。 In this embodiment, the sterilization cycle, the temperature of the actuating movement of the actuator member in the first direction. 当致动器沿第一方向移动时,指示器并不增加或者减小。 When the actuator is moved in a first direction, the indicator does not increase or decrease. 因此,可能发生于单次消毒过程中的多个温度峰值不会导致多次计数变化。 Thus, the temperature may occur in a plurality of sterilization process does not result in a single peak count change times. 相反地,在使用循环中,机械致动元件沿第二方向移动致动器,导致指示器的增加/减小。 In contrast, the use cycle, the mechanical actuating movement of the actuator member in the second direction, resulting in the pointer increase / decrease. 机械致动元件的一个部分(例如机械撞杆)从电外科器械延伸。 A mechanical part of the actuator element (such as a mechanical ram) extends from the electrosurgical instrument. 当医生使用该电外科器械时——例如通过将器械的一个插头部分插入成与电外科发电机电接合,机械致动元件被压入。 When the doctor using the electrosurgical instrument - for example by a plug inserted into a portion of the instrument and electrosurgical generator electrically engaged, mechanically actuating element is pressed into. 机械致动元件的压入使得致动器沿第二方向移动并导致指示器的增加/减小。 Press-mechanical actuator such that the actuator member moves in the second direction and cause the indicator to increase / decrease. 致动器不能导致指示器的另一次增加/减小,直至温度致动元件在后续的消毒过程中再次沿第一方向移动致动器。 The actuator can cause another pointer increase / decrease until the temperature of the actuating element in the subsequent sterilization process to move the actuator in the first direction again. 通过结合地使用温度致动元件和机械致动元件而实现指示器的改变,对于完成的每次消毒/使用循环,计数器/闭锁机构实现了单次地增加/减小。 By combining the use of temperature-actuated mechanical actuator member and effect a change in the indicator element, for each sterilization / use cycle is completed, the counter / latch mechanism to achieve a single increase / decrease.

依据本发明的另一个方面,当电外科器械已经经历了预定次数的消毒/使用循环时,计数器/闭锁机构阻止电外科器械被使用。 According to another aspect of the present invention, when the electrosurgical instrument has undergone the predetermined number of sterilization / use cycle, counter / lockout mechanism prevents electrosurgical instrument being used. 在本发明的一个实施方式中,计数器/闭锁机构包括有一个机械撞杆,一旦已经进行了预定次数的消毒/使用循环,该机械撞杆物理地阻止器械被使用。 In one embodiment of the present invention, a counter / lockout mechanism includes a mechanical lance, once it has been performed a predetermined number of sterilization / use cycle, the lance physically prevents mechanical instruments are used.

现在参照附图,图1到图4B示出了依据本发明的第一实施方式,图5到图9示出了依据本发明的第二实施方式,而图10示出了依据本发明的第三实施方式。 Referring now to the drawings, FIG. 1 to FIG. 4B shows a first embodiment according to the present invention, FIG. 5 to FIG. 9 shows an embodiment according to the second embodiment of the present invention, and FIG. 10 shows a first in accordance with the present invention third embodiments.

如在此所使用的,以下的术语应当具有以下的意义:术语“消毒/使用循环”应当指电外科器械的消毒以及使用,而不管这些活动发生的顺序。 As used herein, the following terms shall have the following meanings: The term "sterilization / use cycle" shall refer to use of the electrosurgical instrument and sterilized, and regardless of the order of these activities. 虽然本发明的描述方式为“消毒/使用循环”,应当理解本发明的教示是足够地广的,并意图包括“使用”在“消毒”之后的情形,反之亦然;关键之处在于:在每次电外科器械的连续使用之间(不管认为消毒过程发生于给定的使用之前或者之后),本发明的计数器/闭锁机构仅仅增加/减小单个计数。 While the embodiment of the present invention is described in "Disinfection / use cycle", it should be understood that the teachings of the present invention is sufficiently broad, and is intended to include after "sterilization" in the case of "use" and vice versa; key point is that: in between each successive use of the electrosurgical instrument (whether before or after the sterilization process that occurs in a given use), the present invention counter / lockout mechanism is just to increase / decrease a single count.

术语“减小/增加”应当指结合在本发明计数器/闭锁机构中所使用的计数的减小或者增加,以指示消毒/使用循环的完成。 The term "decreasing / increasing" shall mean the present invention is incorporated to reduce the counter / lockout mechanism used in the count or increasing, indicating disinfection / use cycle is completed. 虽然在此公开的本发明的实施方式描述为:对于每次消毒/使用循环,计数器/闭锁机构“减小”,但是应当理解,本发明的教示是足够广泛的,并意图包括计数器/闭锁机构对于每次消毒/使用循环而“增加”的情形。 While the embodiments of the invention disclosed herein are described as follows: for each sterilization / use cycle, counter / lockout mechanism "reduced", it should be understood that the teachings of the present invention is sufficiently broad, and is intended to include a counter / lockout mechanism for each case of sterilization / use cycle "increase" of.

此外,在此将使用下文的约定来描述本发明计数器/闭锁机构各个构件的取向。 In addition, the convention will be used herein below to describe the orientation of various components of the present invention, a counter / lockout mechanism.

大体上对于电外科仪器而言,“远端”通常指活性电极,通过该活性电极对患者进行电外科手术。 For substantially electrosurgical instrument, the "distal" generally refers to the active electrode, electrosurgery through the active electrode to the patient. 由于在此公开的本发明计数器/闭锁机构的优选实施方式容置于一个插件内——其中该插件用于将电外科电极连接到电外科发电机,所以,“远端”当指计数器/闭锁机构与电外科仪器最接近的那一端(即与图1A中的电源线4最接近的一端),而“近端”当指计数器/闭锁机构与电外科仪器最远的那一端(即在图1A中带有端头8a-c的一端)。 Since the preferred embodiment of the present invention disclosed herein counter / lockout mechanism is housed within a plug - wherein the plug-in connection for electrosurgical electrode to the electrosurgical generator, thus, "distal" when referring to the counter / lockout mechanism electrosurgical instrument closest to that end (i.e. end in FIG. 1A closest power supply line 4), and "proximal" when referring to the counter / lockout mechanism that end furthest electrosurgical instrument (i.e., in FIG. One end of the tip 8a-c with. 1A). 有时,构成本发明计数器/闭锁机构的各个构件的朝向也可以类似的术语表达。 Sometimes, the individual components constituting the facing of the present invention, a counter / lockout mechanism may also be expressed similar terms.

现在参照示于图1到4B中的实施方式,所述附图示出了依据本发明的第一实施方式,其中电外科器械1包括有计数器/闭锁机构10。 Referring now to FIG. 1 shown in the embodiments 4B, the drawings illustrate a first embodiment according to the present invention, wherein the electrosurgical instrument includes a counter / lockout mechanism 10. 计数器/闭锁机构10位于电外科器械1的电源连接器中,所述电源连接器构造成插入一个电外科的电源中——例如一个电外科发电机(未示)。 Counter / latch mechanism 10 is located electrosurgical instrument power supply connector 1, the power connector is configured to be inserted into an electrosurgical power supply - for example an electrosurgical generator (not shown). 电外科器械1包括用于保护电外科器械1内部构件的壳体2、用于将电外科电流从发电机(未示)输送到电外科仪器(未示)的电源线4、用于观察指示器22上的一个或多个指示的窗口6、以及用于将电外科器械1连接到电外科电源(未示)的端头8a-c。 The electrosurgical instrument comprises a housing 1 for a protection of the inner member 2 of the electrosurgical instrument for conveying an electrosurgical current from the generator (not shown) to an electrosurgical instrument (not shown) of the power supply line 4 for visual indication of the one or more indications of the window 22 6, and an electrosurgical instrument for connection to an electrosurgical power source (not shown) of the tip 8a-c.

现在开始讨论图1A,计数器/闭锁机构为电外科器械1的一个部分。 The discussion now to Figure 1A, the counter / lockout mechanism is a part of the electrosurgical instrument 1. 计数器/闭锁机构跟踪电外科器械1已经经历的消毒/使用循环的次数,并且一旦在完成了预定次数的消毒/使用循环之后阻止电外科器械1被使用。 Counter / latch mechanism to track the number of times the electrosurgical instrument has been subjected to a sterilization / use cycle, and once completed the blocking electrosurgical instrument 1 is used after sterilization / use cycle of a predetermined number of times. 在此将对计数器/闭锁机构的构件如何地一起工作而跟踪所执行的消毒/使用循环的次数、并之后阻止器械的进一步使用进行论述。 How this will be counter / lockout mechanism member work together to track frequency and disinfection performed / use cycle, and then prevent further use of the instrument will be discussed. 如同本领域内的技术人员所理解的那样,可采用多种类型及构造的机构而不会偏离本发明的范畴和精神。 As those skilled in the art, as understood, may be employed and the construction of various types of mechanism without departing from the scope and spirit of the invention. 例如,在一个实施方式中,可以使用计数器机构而不使用闭锁机构。 For example, in one embodiment, the counter mechanism can be used without using the locking mechanism. 在另一个实施方式中,可以使用闭锁机构而不使用计数器机构。 In another embodiment, the latching mechanism may be used without using the counter mechanism.

机械撞杆40与电外科器械1的其它构件一起操作,从而使得与电外科器械1一起使用的计数器/闭锁机构10可以正确地工作。 Mechanical lance 40 operates together with other members of an electrosurgical instrument, so that the counter / lockout mechanism used with the electrosurgical instrument 110 can work properly. 例如,机械撞杆40与计数器/闭锁机构10的其它构件一起操作而减小指示器22的标记。 For example, a mechanical striker member 40 and the other counter / lockout mechanism 10 is reduced with operation indicator 22 is marked. 在所示的实施方式中,机械撞杆40位于端头8a和8b之间,从而使得当端头8a-c插入到一个电外科电源(未示)内时,机械撞杆40将被压入。 In the embodiment shown, the mechanical striker 40 positioned between the ends 8a and 8B, so that when the tip 8a-c is inserted into an electrosurgical power source (not shown) within the mechanical striker 40 will be pressed into the . 使得当端头8a-c插入到一个电外科电源(未示)内时,机械撞杆40接触壁、插座、或者其它的表面,从而使得端头8a-c所插入的电源壳体将机械撞杆40迫入到壳体2内。 Such that when the tip 8a-c is inserted into an electrosurgical power source (not shown) within, the mechanical striker 40 contacts wall socket, or other surface, so that the tip 8a-c inserted mechanical power striker housing forcing the rod 40 into the housing 2.

在所示的实施方式中,机械撞杆40处于部分伸出的位置上。 In the embodiment shown, the mechanical position of the lance 40 is in the extended portion. 当预定次数的消毒/使用循环还没有达到时,机械撞杆40抵达部分伸出位置。 When a predetermined number of sterilization / use cycle has not been reached, the lance 40 to a mechanical partially extended position. 机械撞杆40是用于探测使用循环的装置的一个示例。 Mechanical lance 40 is one example of means for detecting use cycles. 用于探测使用循环的其它这种装置对于本领域的技术人员而言是公知的。 Other such devices used for detecting cycles for those skilled in the art are well known. 例如,用于后续使用的钥匙的可移除的撞针、以及带有芯片的软件、电光源、条线图、可用作探测使用循环的装置。 For example, the striker key for subsequent use removable, and software with chips, electric light, a bar graph may be used as means for detecting the use of cycles.

如本领域内的技术人员所理解的那样,多种类型及构造的电外科计数器/闭锁机构可与多种类型及构造的电外科器械一起使用而不会偏离本发明的范畴和精神。 As those skilled in the art appreciate, various types of electrosurgical counter constructed and / latching mechanism may be used with a variety of electrosurgical instruments of the type and configuration without departing from the scope and spirit of the invention. 例如,在一个实施方式中,计数器/闭锁机构用于一个外科电笔或者其它仪器的体部内,而不是用于电源连接器内。 For example, in one embodiment, the counter / latch mechanism for the inner body portion is electrically a pen or other surgical instruments, rather than for the power connector. 在另一个实施方式中,计数器/闭锁机构用于模块化电外科器械的一个部分中,该部分在与所述电外科器械的其它部分分离之后进行消毒。 In another embodiment, the counter / lockout mechanism for a modular electrosurgical instrument portion, the portion to be sterilized after the separation of other portions of the electrosurgical instrument. 在另一个实施方式中,指示器示出已经完成的消毒/使用循环的次数,该次数为所推荐的消毒/使用循环次数的函数。 In another embodiment, the indicator shows the number of completed sterilization / use cycle, as a function of the number of times the recommended disinfection / use cycle number.

图1B为电外科器械1的俯视图,其中示出机械撞杆40处于压入位置。 1B is a plan view of an electrosurgical instrument, wherein the mechanical striker 40 is shown in the depressed position. 为了清晰起见,所示出的端头8a-c没有插入到电外科的电源内。 For the sake of clarity, the ends 8a-c is not shown inserted to an electrosurgical power supply. 如本领域内的技术人员可以理解的那样,在一个典型的使用设置中,由于端头8a-c被插入到插座或者其它的电外科电源(未示)内,机械撞杆40被推入到电外科器械1的壳体2内。 As those skilled in the art can appreciate, in a typical arrangement used, since the tip 8a-c is inserted into the receptacle or other electrosurgical power source (not shown), the mechanical striker 40 is pushed into the the electrosurgical instrument 2 within the housing 1. 因为机械撞杆40被推入到电外科器械1的壳体2内,指示器22沿电源线4的方向滑动,使得指示器22的一个或者多个标记得以改变。 Because the mechanical striker 40 into electrosurgical instrument 1 is pushed inside the housing 2, the indicator 22 slides in the direction of the power line 4, such that the one or more indicator marks 22 is changed. 标记的改变向使用者指示:与图1A所指示的相比,所剩余的使用次数已经减少了一次。 Marked changes indicate to the user: in comparison with FIG. 1A indicated, remaining number of uses has been reduced once.

图1C示出了电外科器械1,其中机械撞杆40处于完全伸出位置。 FIG 1C shows an electrosurgical instrument, wherein the mechanical striker 40 is in the fully extended position. 在所示的实施方式中,机械撞杆40从电外科器械1的壳体2所伸出的长度与端头8a-c的长度大致相等。 In the embodiment shown, the mechanical length and the lance tip 8a-c from an electrosurgical instrument housing 240 of the projecting substantially equal. 当完成了预定数量的消毒/使用循环次数后,机械撞杆40移到完全伸出的闭锁位置。 Upon completion of a predetermined number of sterilization / use cycles, the machine 40 moves to the fully extended position of the locking lance. 当机械撞杆40移到完全伸出的闭锁位置时,它不能够再被推入到壳体2内。 When the latch 40 moves to the fully extended position of the ram of mechanical, it can no longer pushed into the housing 2. 在这个构造中,机械撞杆40物理地防止端头8a-c与电源(未示)相连,从而阻止了电外科器械1的进一步的使用。 In this configuration, the machine 40 to physically prevent the lance tip 8a-c power supply (not shown) is connected, thus preventing further use of an electrosurgical instrument. 当机械撞杆40处于完全伸出的闭锁位置时,窗口6使得使用者可以观察指示器22并且确定:电外科器械1没有剩余的使用次数。 When the mechanical locking lance 40 is in the fully extended position, so that the user can observe the window 6 and the indicator 22 is determined: the electrosurgical instrument 1 has no remaining number of uses.

如本领域内的技术人员所公知的那样,可采用多种类型以及构造的计数器/闭锁机构而不会偏离本发明的范畴和精神。 As those skilled in the art as well known, various types may be employed and a counter / lockout mechanism is configured without departing from the scope and spirit of the invention. 例如,在一种实施方式中,闭锁机构的机械撞杆可以两个或多个不同的伸出量从壳体伸出。 For example, in one embodiment, the mechanical locking mechanism can lance two or more different projecting amounts protrudes from the housing. 在另一种实施方式中,撞杆可以单一的伸出量从壳体伸出,其作用在于减小指示器以及提供闭锁功能。 In another embodiment, the lance may be a single protrusion amount projecting from the housing, the effect is to reduce the indicator, and provide a latching function. 在另一种实施方式中,把第一机构用作一个机械致动元件来减小计数器,而把第二机构用作一个闭锁机构。 In another embodiment, the first mechanism as a mechanical actuator to reduce the counter element, whereas the second means serves as a locking mechanism. 在另外的实施方式中,撞针从壳体伸出的距离可以大于或者小于端头的长度。 In a further embodiment, the striker projecting from the housing a distance may be greater than or less than the length of the tip.

所示出的指示器22的构造使得使用者可以在应当丢弃电外科器械1之前对所剩余的使用次数进行监测。 Indicator 22 is configured such that the user may be shown in the electrosurgical instrument should be discarded using the remaining number of times before a monitor. 通过示出剩余的使用次数,为使用者提供了足够的机会,使得其可在将进行手术之前对电外科器械1进行替换。 By use of the remaining number is shown, provide the user with sufficient opportunity, so that it can electrosurgical instrument 1 prior to replacement surgery. 如本领域内的技术人员所理解的那样,可采用多种类型及构造的计数器/闭锁机构而不会偏离本发明的范畴和精神。 As those skilled in the art appreciate, it may take a variety of types and configurations of counter / latch mechanism without departing from the scope and spirit of the invention. 例如,在一个实施方式中,可使用这样的计数器/闭锁机构:其阻碍或者防止电流从端头流向电源线。 For example, in one embodiment, the use of such counter / lockout mechanism: which hinder or prevent the current flowing from the power supply line ends. 在一个可选地实施方式中,一旦完成了预定的消毒/使用循环次数,则计数器/闭锁机构可以使得模块化电外科器械构件在手术之前不能正确地组装。 In an alternative embodiment to the embodiment, upon completion of a predetermined sterilization / use cycles, the counter / lockout mechanism may be such that the modular member of the electrosurgical instrument can not be correctly assembled prior to surgery.

图2为电外科器械1的内部立体视图,其示出了依据本发明一个实施方式的计数器/闭锁机构10。 FIG 2 is a perspective view of the interior of the electrosurgical instrument 1, which is shown in accordance with one embodiment of the present invention the counter / lockout mechanism 10. 在所示的实施方式中,计数器/闭锁机构10包括有指示器组件20、机械撞杆40、偏置弹簧48、致动器50、温度致动元件70、弹簧80、以及致动器接合构件90。 In the illustrated embodiment, the counter / lockout mechanism 10 includes an indicator assembly 20, a mechanical striker 40, the biasing spring 48, the actuator 50, the temperature of the actuating member 70, spring 80, and an actuator engagement member 90.

通过一个机械致动元件(即机械撞杆40)以及一个温度致动元件70而使得致动器50可以正确地操作。 By a mechanical actuating element (i.e., a mechanical striker 40) and a temperature of the actuating member 70 such that the actuator 50 can operate correctly. 在每次使用电外科器械1时,机械撞杆40被致动。 Each use an electrosurgical instrument, the lance 40 is mechanically actuated. 温度致动元件70的操作与每次所进行的消毒循环相联系。 The temperature of the actuating member 70 and the operation performed by each sterilization cycle linked. 机械撞杆40与温度致动元件70的结合导致:对于进行的每次消毒/使用循环,致动器50单次致动。 Mechanical lance 40 and the temperature of the actuator 70 causes binding member: for each sterilization / use cycle, the actuator 50 a single actuation. 在一个实施方式中,温度致动元件70与机械撞杆40配合地使得致动器50沿第一和第二方向移动。 In one embodiment, the temperature of actuating member 70 with mechanical striker 40 with the first and second directions such that the actuator 50 moves along. 这使得致动器50可以移动指示器22并实现一个或多个标记的变化,以显示消毒/使用循环已经结束。 This enables the actuator 50 to move the pointer 22 and implement changes in one or more markers to show sterilization / use cycle has ended.

在所示的实施方式中,机械撞杆40包括销或者杆并包括近端42与远端44。 In the embodiment shown, the mechanical striker 40 includes a pin or rod and includes a proximal end 42 and distal end 44. 近端42位于端头8a和端头8b之间,并且在伸出位置和压入位置之间选择地移动。 Positioned between the proximal end 42 and a tip end 8a 8b, and selectively moved between the extended position and a depressed position. 机械撞杆40的远端44邻近于致动器50和指示器22(视图3A),并构造成与致动器50接合而移动指示器22。 Mechanical lance 44 adjacent the distal end 40 of the actuator 50 and an indicator 22 (view 3A), and configured to engage with the actuator 50 to move the pointer 22. 压入机械撞杆40导致致动器50移动。 Lance 40 is pressed into mechanical movement of the actuator 50 results in actuation. 在所示的实施方式中,机械撞杆40的近端42处于伸出的位置。 In the embodiment shown, the proximal end 40 of the mechanical lance 42 is in the extended position. 当机械撞杆40被朝远端偏置时,机械撞杆40的远端44与致动器50接合。 When the lance 40 is mechanically biased toward the distal end, the distal end of shaft 40 mechanically engages the striker 44 with the actuator 50. 这导致致动器50朝远端方向移动。 This causes the actuator 50 moves toward the distal direction.

在所示的实施方式中,温度致动元件70由形状记忆合金——例如为但是并不限于Nitinol。 In the illustrated embodiment, the temperature of the actuating member 70 of a shape memory alloy - for example, but not limited to Nitinol. 当温度致动元件70处于足够的温度下时,其回复到初始的形状并且是刚性的,不易于弯曲。 When the temperature of actuating member 70 is under sufficient temperature, it returns to its original shape and is rigid and difficult to bend. 从而,当电外科器械1经历一次消毒循环时,由于温度致动元件70的变硬,温度致动元件70从一个弯曲的构形变化成所示的更呈直线型的构形。 Thus, when an electrosurgical instrument undergoes a sterilization cycle, since the temperature-induced hardening of the movable member 70, the temperature of the actuator 70 from a curved configuration as shown more variation element linear type configuration. 温度致动元件70的变硬将致动器50推往端头8a-c的方向。 Hardening temperature of the actuator element 70 of the actuator 50 in the direction of the tip 8a-c to push. 这导致致动器50相对于指示器22移位。 This causes the actuator 50 with respect to the displacement indicator 22. 温度致动元件70为用来探测高于室温的温度的装置的一个示例。 The temperature of the actuating member 70 is for example a temperature above room temperature detecting means. 可采用多种类型及构造的装置来探测高于室温的温度而不会偏离本发明的范畴和精神。 Types variety of devices can be configured to detect a temperature above room temperature without departing from the scope and spirit of the invention. 例如,在一个实施方式中,可采用这样的温度致动元件:其磁性可随温度变化。 For example, in one embodiment, the temperature of the actuator may be employed such element: its magnetic properties can vary with temperature. 在另一个实施方式中,可采用这样的一种温度致动元件:其包括一个响应温度波动的液体部分或者填充有液体的部分。 In another embodiment, such a temperature may be employed actuating element: in response to temperature fluctuations which comprises a portion of the liquid or partially liquid filled.

偏置弹簧48包绕着机械撞杆40。 Mechanical biasing spring 48 around the lance 40 packet. 偏置弹簧48将机械撞杆40偏置向近端方向,从而使得当机械撞杆40的近端42不与壁、插座或者其它表面接触时从壳体2伸出。 Mechanical biasing spring 48 will bias the striker 40 in the proximal direction, so that the proximal end of lance 40 when the machine 42 is not, protrude from the housing 2, or other contact with the wall surface of the receptacle. 当完成了预定次数的消毒/使用循环之后,弹簧80促使机械撞杆40抵达闭锁位置。 When a predetermined number of times after completion of the sterilization / use cycle, the spring 80 causes the lever 40 to a mechanical striker latched position. 致动接合构件90促使致动器50横向移动,以确保对于致动器50的每次致动,指示器22单次地减小。 Actuating the engagement member 90 causes the actuator 50 moves laterally, in order to ensure for each actuation of the actuator 50, a single indicator 22 decreases. 此外,致动接合构件90与机械撞杆40相互作用,从而保持住机械撞杆40的期望的移动路径,同时控制机械撞杆40的伸出,直至完成了预定次数的消毒/使用循环。 In addition, the actuating member 90 engages the striker bar 40 interacts with a mechanical, moving path so as to maintain a desired living mechanical lance 40, while the control mechanism extending lance 40, until the completion of a predetermined number of sterilization / use cycle.

在所示的实施方式中,指示器22包括标记24、齿26、导引槽27(视图2)、以及闭锁部分28。 In the embodiment shown, the indicator 22 includes a marker 24, the teeth 26, the guide groove 27 (Figure 2), and a latching portion 28. 标记24位于指示器22的上表面上。 Marks 24 located on the upper surface of the indicator 22. 在所示的实施方式中,标记24包括有多个线条以及相关的参考标号。 In the embodiment shown, the marker 24 comprises a plurality of lines and associated reference numerals. 多个线条以及相关的参考标号指示在应当丢弃电外科器械1之前剩余的使用次数。 A plurality of lines and associated reference numerals used a number of times before remaining in the electrosurgical instrument should be discarded. 指示器22的位置如此地选择:当相应的剩余使用次数还没有进行时,适当标记(线条以及相关的参考标号)的位置设在可通过窗口6观察到之处(视图1A-1C)。 The position indicator 22 is selected in such a way: When the remaining number of times the corresponding use has not performed an appropriate position mark (and associated lines, reference numeral) may be provided at the (view 1A-1C) were observed through the window 6. 随着指示器22离开其近端,通过窗口6(图1)观察到的一个或多个标记也变化了。 As the indicator 22 out of its proximal end, it is observed through the window 6 (FIG. 1) one or more markers are also changed. 在所示的实施方式中,指示器22朝远端方向的移动使得计数器减小。 In the embodiment shown, the distal direction movement indicator 22 causes the counter is reduced.

齿26与致动器50配合地相互作用而沿远端方向移动指示器22。 The teeth 26 and the actuator 50 interacts with the indicator 22 is moved in the distal direction. 选择齿26的数目、尺寸、以及位置,使得对于每次进行的消毒/使用循环,标记24单个地减小。 Select the number of teeth 26, size, and position, such that for each time the sterilization / use cycle, a single mark 24 decreases. 在所示的实施方式中,齿26相对于指示器22体部的远端方向伸出促进致动器50相对于指示器22移位到更远的位置。 In the embodiment shown, the teeth 26 relative to the distal direction of the body portion 22 of the indicator actuator 50 projecting facilitate relative indicator 22 is shifted to a position farther. 如图2所示,一个导引槽27位于指示器22的下侧,用来容纳导引件29。 2, a guide groove 27 located on the lower side of the indicator 22, for receiving the guide member 29. 导引槽27与导引件29配合地相互作用,从允许指示器22在指示器从一个较近的位置移动到一个较远的位置时平滑且可预测地移动。 The guide groove 27 and the guide member 29 cooperatively interact, while allowing smooth indicator 22 from moving from a position close to a distant position indicator and movable predictably.

回到图3A,闭锁部分28位于机械撞杆40附近、处于指示器22的近角内。 Back to Figure 3A, the locking portion 28 is located near the mechanical lance 40, 22 is nearly the angle indicator. 闭锁部分28构造成:当指示器22移向其最远的位置时,机械撞杆40可以沿横向移离致动接合构件90。 Latching portion 28 is configured to: when the indicator 22 moves to its farthest position, the lance 40 may be mechanically moved away from the actuation direction engages the transverse member 90. 爪簧30紧固在指示器22上。 A pawl spring 30 in the indicator 22 is fastened. 爪簧30与紧固构件34协作,从而使得指示器22的意外运动得最小化。 Pawl spring 3034 cooperate with the fastening member, so that the accidental movement indicator 22 have minimized. 爪簧30包括弹性臂31以及爪簧接合齿32。 Pawl spring 30 includes a resilient arm 31 and the pawl spring 32 engages the teeth. 弹性臂31变形而使得爪簧接合齿32可以相对于紧固构件34的齿移动。 Elastically deformable arm 31 such that the teeth 32 engage the pawl spring can move relative to the tooth 34 of the fastening member. 爪簧接合齿32构造成设置在紧固构件34的各组齿之间、或者接合紧固构件34的一个或多个齿、或者位于紧固构件34的相邻齿之间,从而使得指示器22的意外运动得以最小化。 Pawl spring engagement tooth 32 is configured to be disposed between each set of teeth 34 of the fastening member, the fastening member or engaging one or more teeth 34, the fastening member or located between adjacent teeth 34, so that the indicator 22 unexpected movement is minimized. 当致动器50使得指示器22移动时,弹性臂31的柔性足以允许爪簧接合齿32沿指示器22的方向移离紧固构件34。 When the actuator 50 such that movement of the pointer 22, the resilient arm 31 is flexible enough to allow the indicator 22 along the direction of the teeth 32 engage the pawl spring 34 to move away from the fastening member. 这使得爪簧接合齿32可以从位于第一组齿之间的位置移走、越过第一组齿中的远齿、并进入到第二组齿之间。 This allows the pawl spring engagement tooth 32 may be removed from position between the teeth of the first set, the first set of teeth over the distal tooth, and enters between the second set of teeth. 在所示的实施方式中,爪簧接合齿32位于第一组齿之间。 In the embodiment shown, the teeth 32 engage the pawl spring is located between the first set of teeth. 这是因为:电外科器械1还没有经历过第一次使用循环,并且机械撞杆40还没有在第一次使用循环中被压入。 This is because: the electrosurgical instrument has not experienced a first time cycle, and a mechanical striker 40 is not yet pressed into the loop the first time.

如本领域内的技术人员所理解的那样,可使用多种类型及构造的指示器而不会偏离本发明的范畴和精神。 As those skilled in the art appreciate, various types of indicators can be used and configured without departing from the scope and spirit of the invention. 例如,在一个实施方式中,指示器包括七段显示器,所述指示器示出在应当丢弃电外科器械之前所剩余的使用次数。 For example, in one embodiment, the indicator includes a seven-segment display, the indicator is shown in the number of uses should be dropped before the remaining electrosurgical instrument. 在另一个实施方式中,指示器包括有一个环形元件。 In another embodiment, the indicator comprises an annular element. 在另一个实施方式中,指示器是齿轮驱动的。 In another embodiment, the indicator is a gear drive. 在另一个实施方式中,指示器包括数字显示器。 In another embodiment, the indicator comprises a digital display.

继续参考图3A,致动器50配合地接合指示器22而导致指示器22向后运动。 With continued reference to Figure 3A, actuator 50 engages the indicator 22 with indicator 22 caused by rearward movement. 在所示的实施方式中,致动器50包括有突起52、凸轮槽56、指示器接合齿60、以及槽64,在图2中更为详细地示出了槽64。 In the embodiment illustrated, the actuator 50 includes a protrusion 52, the cam groove 56, the teeth 60 engage the indicator, and a groove 64, shown in FIG. 2 in more detail the grooves 64. 如图3A所示,突起52与致动接合构件90相互作用而促使致动器50枢转运动。 3A, the protrusion 52 interacting with the actuating member 90 engaging the actuator 50 causes the pivoting movement. 凸轮槽56与销58相互作用而导致致动器50向后运动,同时还使得致动器50可以响应于机械撞杆40的压入而枢转地运动。 The cam groove 56 and the pin 58 resulting from the interaction of the backward movement of the actuator 50, and also so that the actuator 50 may be responsive to a mechanical lance 40 is pressed and is pivotally moved. 致动器50的枢转运动使得致动器50将指示器22移动单个的减小量,而与在单次消毒/使用循环后指示器22的移动距离和机械撞杆40的移动距离的差无关。 The actuator 50 causes the pivotal movement of the 50 single pointer 22 is moved to reduce the amount of the actuator, and the difference between the moving distance after a single sterilization / use cycle mechanical indicator 22 and a moving distance of the lance 40 nothing to do.

在致动器50的初始后向运动期间,指示器接合齿60与指示器22的齿26接合。 After the initial actuation of the actuator 50 during the movement, the indicator 60 and the engagement teeth 22 are teeth 26 pointer. 在致动器50朝电源线4运动的期间,随着致动器50的近部开始横向枢转,指示器接合齿60脱离指示器22的齿26。 4 during movement of the actuator toward the power supply line 50, as the actuator starts near the transverse pivot portion 50 of the indicator departing from the teeth 26 engage the teeth 60 of the indicator 22. 一旦指示器接合齿60脱离指示器22的齿26,指示器22进一步的向后运动停止。 Once the indicator teeth 26 engage the teeth 60 from the indicator 22, the indicator 22 stops further rearward movement.

在所示的实施方式中,弹簧80的第一端82接触致动器50的突起52并通过形成于壳体2中的支撑结构88而保持在期望的位置上。 In the embodiment shown, the contact spring 80 a first end 82 of the actuator 50 and the projection 52 is held in a desired position by the support structure 88 is formed in the housing 2. 当机械撞杆40不位于致动器50和指示器22之间时,弹簧80的第一端82将突起52偏置向指示器22,从而使突起52置于致动接合构件90附近。 When the machine 40 is not located between the lance 50 and the indicator 22 of the actuator, the first end 82 of the spring 80 will bias the projection 52 to the indicator 22 so that the engaging projection 52 disposed near the actuating member 90. 致动器50包括槽64(也见视图2)。 The actuator 50 includes a slot 64 (see also Figure 2). 槽64容置温度致动元件70的近端72。 Temperature of the accommodating groove 64 proximal end of the actuating member 70 is 72. 通过使得温度致动元件70可以相对于致动器50简单有效地定位,槽64有利于闭锁/计数器机构10的组装。 Element 70 with respect to the actuator 50 simply and effectively by making the temperature of the actuator is positioned, the locking grooves 64 facilitate assembly / counter mechanism 10. 槽64以及温度致动元件70的构造使得致动器50响应于消毒循环而根据需要运动,而无需计数器/闭锁机构10部件过分精确地制造或组装。 Configured grooves 64 and the temperature of actuating member 70 so that the actuator 50 is responsive to the sterilization cycle required movement and member 10 without counter / lockout mechanism excessively precisely manufactured or assembled.

将参照图3B-4B非常详细地描述致动器50的操作。 With reference to FIGS. 3B-4B of the operation 50 is described in detail in the actuator. 图3B为电外科器械1的内部俯视图,其示出致动器50响应于机械撞杆40的部分压入的运动。 FIG 3B is a plan view of the interior of the electrosurgical instrument of FIG. 1, which shows the response 50 of the actuator portion 40 is pressed into mechanical movement of the lance. 在所示的实施方式中,机械撞杆40的近端52已经朝远端方向移动,但是其移动程度没有使机械撞杆40的整个长度都位于壳体2的内部。 In the embodiment shown, the mechanical striker has moved proximal end 5240 toward the distal direction, but not the extent of the mechanical movement of the entire length of the lance 40 are located inside the housing 2. 随着机械撞杆40被朝远侧偏置时,机械撞杆40的远端44与致动器50接合。 With mechanical lance 40 is pushed distally biased mechanical lance 44 engages the distal end 40 of the actuator 50. 这导致致动器50朝远端方向移动。 This causes the actuator 50 moves toward the distal direction. 随着致动器50朝远端方向移动,指示器接合齿60与指示器22的一个齿26接合。 As the actuator 50 moves toward the distal direction, the indicator 60 and engaging a tooth 26 engages the teeth of the indicator 22. 当致动器50与指示器接合齿60接合时,随着致动器50向远侧移动,指示器22沿远端方向移动。 When the indicator actuator 50 to engage the engaging teeth 60, as the actuator 50 moves distally, the indicator 22 moves in the distal direction. 当指示器22沿远端方向移过一个预定的距离时,实现了标记的改变。 When the distal direction indicator 22 moves through a predetermined distance, to achieve a marked change. 标记的改变为使用者示出在所完成的消毒/使用循环之后剩余的使用次数。 Mark shows the user changes the number of uses remaining after the completion of the sterilization / use cycle. 在所示的实施方式中,随着致动器50起先的0.06英寸的移动,标记的改变且爪簧接合齿32移动。 In the embodiment illustrated, with the movement of 0.06 in the actuator 50 at first, and marks the change pawl spring 32 engages the teeth movement.

随着机械撞杆40被进一步压入到电外科器械1的壳体内(从图3B的位置移动到图3C的位置),致动器50枢转离开指示器22,防止指示器22进一步向后移动。 As is further pressed into the electrosurgical instrument (FIG. 3B is moved from position to position in FIG. 3C) a mechanical striker housing 401, the actuator switch 50 away from the pivot indicator 22, the indicator 22 to prevent further rearward mobile. 在图3B中,致动器50的近部开始枢转离开指示器22的齿26。 In FIG. 3B, the proximal portion of the actuator 50 begins to pivot away from the teeth 2622 of the indicator. 然而,致动器接合齿60还没有与齿26分开。 However, the actuator engages the teeth 60 and the teeth 26 are not separated. 突起52以及致动器接合构件90的构造便于致动器50从指示器22枢转离开。 And the configuration of the projection 52 of the member 90 engages the actuator to facilitate the rotation of the actuator 50 away from the pivot indicator 22. 在机械撞杆40被压入之前,突起52位于致动器接合构件90的凹槽92中,如图3A所示。 Before the mechanical striker 40 is press-fitted, the protrusion 52 is located the actuator member 90 in the engaging groove 92, shown in Figure 3A. 当机械撞杆40开始沿如图3B所示地向后移动致动器50时,突起52的横向移动表面54接触致动器接合构件90的横向移动表面94。 When the mechanical striker 40 starts moving along the actuator in FIG. 50, lateral movement of the protrusion 52 contacts surface 54 of actuator 90 engages a transverse member 94 of the moving surface rearwardly as shown in 3B. 横向移动表面54与横向移动表面94之间的相互作用导致突起52开始枢转离开指示器22。 The interaction between the lateral moving surfaces 94 and 54 cause the lateral movement of the surface of the protrusion 52 starts to pivot away from the pointer 22.

一旦突起52开始枢转,机械撞杆40的远端44开始与指示器接合齿60的斜面62接触。 Once the protrusion 52 starts pivoting, the distal end 40 of mechanical lance 62 contacts the inclined surface 44 of the tooth 60 begins to engage with the indicator. 当机械撞杆40的远端44被沿远端方向推动时,机械撞杆40沿斜面62的长度滑动。 When the distal end 44 of mechanical striker 40 is pushed in the distal direction, the mechanical striker 40 along the length of the inclined surface 62 of the slide. 这导致突起52进一步地枢转、且横向移离指示器22。 This causes the projection 52 is further pivoted, and laterally moved away from the indicator 22. 突起52的横向移动还导致指示器接合齿60的横向移动。 Lateral movement of the protrusion 52 also causes the lateral movement of the indicator engages the teeth 60. 凸轮槽56与销58的构造使得致动器50可以枢转运动,该枢转运动由于下列因素而变得容易:(a)横向移动表面54与94之间的相互作用;以及(b)机械撞杆40的远端44与指示器接合齿60的斜面62之间的相互作用。 The cam groove 56 and the pin 58 is configured such that the actuator 50 can pivot movement, the pivoting movement is easy due to the following factors: (a) the interaction between the surface 54 and the lateral movement 94; and (b) Mechanical the distal end 44 of the lance 40 the interaction between the inclined surface 62 of the teeth 60 engage with the indicator.

当机械撞杆40被多次部分地压入时,指示器22的齿26的构造、以及指示器接合齿60相对于齿26的设置方式防止指示器22多次地减小。 When the mechanical striker 40 is partially pushed several times, the teeth 26 of the indicator 22 is configured of the engagement teeth 60 and an indicator arrangement with respect to the teeth 26 of the indicator 22 is reduced to prevent a plurality of times. 当机械撞杆40被充分地压入而导致指示器22减小时,在对机械撞杆40的后续压入会导致指示器22进一步地减小之前,需要致动温度致动元件70。 When the lance 40 is sufficiently mechanically pressed into the resulting pointer 22 decreases, membership in a subsequent mechanical pressure lance 40 causes the indicator 22 before further reduce the required actuation of the actuating element 70 temperature. 由此,使用者可以多次地插入或者拔出端头8a-c,或者压入机械撞杆40而不会导致指示器22的减小。 Thus, many times a user can insert or remove the tip 8a-c, or pressed into a mechanical striker 40 without causing the indicator 22 decreases.

图3C为电外科器械1的内部俯视图,其中机械撞杆40被完全地压入到壳体2内。 FIG 3C is a plan view of an internal electrosurgical instrument, wherein the mechanical striker 40 is completely pressed into the housing 2. 致动器50的枢转导致指示器接合齿60脱离指示器22的齿26。 The actuator 50 causes the pivoting indicator teeth 26 engage the teeth 60 from the indicator 22. 致动器50和/或机械撞杆40的进一步的后向运动不会使指示器22进一步地移动,因为指示器接合齿60与指示器22的齿是分开的。 The actuator 50 and / or 40 after further mechanical movement of the lance to the pointer 22 does not move further, since the engagement teeth 60 of the indicator the indicator teeth 22 are separated. 机械撞杆40的远端44在指示器接合齿60与齿26之间的移动使得致动器50与指示器22之间保持分开。 Mechanical distal end 44 of the lance 40 moves between the engagement pointer 26 so that the teeth 60 and the teeth 22 of the actuator 50 and the indicator remain separate.

致动器50的枢转运动使得:不管机械撞杆40的移动距离以及指示器22的移动距离如何,致动器50可以令指示器22减小单个位置。 The actuator 50 causes the pivoting movement: Whether mechanical ram 40 moving distance and an indicator of how to move a distance 22, the actuator 50 can be reduced so that a single position indicator 22. 在一个实施方式中,在机械撞杆40的每次致动中,机械撞杆40被压入大致0.25英寸。 In one embodiment, the lance 40 in each mechanical actuation, the mechanical striker 40 is pressed into the substantially 0.25 inches. 在一个实施方式中,在机械撞杆40的每次致动中,指示器22仅仅移动0.060英寸。 In one embodiment, the lance 40 in each mechanical actuation, movement indicator 22 only 0.060 inches. 如本领域内的技术人员所理解的那样,可以相对于指示器的移动量变动机械撞杆的移动量而不会偏离本发明的范畴及精神。 As those skilled in the art appreciate, the relative movement amount of the pointer changes the mechanical ram without departing from the scope and spirit of the invention. 在一个实施方式中,指示器可移动0.01英寸到0.75英寸。 In one embodiment, the indicator can be moved 0.01 inches to 0.75 inches. 在另一个实施方式中,指示器可移动0.02英寸到0.125英寸。 In another embodiment, the indicator can be moved 0.02 inches to 0.125 inches. 在又一个实施方式中,撞杆所移动的距离大于指示器所移动的距离。 In yet another embodiment, the ram moving distance is greater than the distance traveled by the pointer. 在另一个实施方式中,撞杆以及指示器移动的距离至少部分地取决于电外科闭锁机构、以及容置着该电外科闭锁机构的壳体的尺寸。 In another embodiment, the ram moving distance and an indicator at least partially dependent electrosurgical latching mechanism, and the size of the electrosurgical accommodating the latching mechanism of the housing. 此外,可采用多种类型以及构造的致动器而不会偏离本发明的范畴与精神。 Further, the actuator can be a variety of types and configurations without departing from the scope and spirit of the invention.

当致动器50沿远向移动时,力作用在温度致动元件70上,增加温度致动元件70的曲率。 When the actuator 50 moves in the distal direction, the force acting on the actuating element 70 temperature, increasing the temperature of the curvature of the actuating element 70. 当温度致动元件70不因受热而导致温度致动元件70的刚度增加时,温度致动元件70的曲率增加。 When the temperature of actuating member 70 by heat without causing the temperature increase the stiffness of the actuating element 70, the curvature of the temperature of actuating member 70 is increased. 由此,温度致动元件70提供最小的阻力,使得温度致动元件70的远端74更加靠近温度致动元件70的近端72(图2)。 Accordingly, the temperature of the actuating member 70 provides minimal resistance, so that the temperature of the actuating member closer to the distal end 7470 of the proximal end of the actuating element 70 temperature 72 (FIG. 2). 由于温度致动元件70远端74的位置通过座76保持,所以,温度致动元件70的近端72将朝远端74的方向移动。 Since the temperature of the distal end of the actuating member 70 held by the holder 74 in the position 76, so that the temperature of the actuating member 70 of the proximal end 72 moves in the direction of the distal end 74.

一旦致动器50与指示器22脱离,端头的拔出以及随后插入插座中将不会导致指示器22的移动。 Once the actuator 50 and the disengaged indicator 22, and subsequently pulled out of the tip is inserted into the socket will not result in movement of the pointer 22. 原因是因为:指示器接合齿60不再与指示器22接触。 The reason is because: the indicator is no longer in contact with the teeth 60 engage the indicator 22. 机械撞杆40沿端头8a-c方向的移动不会导致致动器50朝指示器22方向移动,也不会导致指示器22由指示器接合齿60接合。 Mobile mechanical striker 40 along the direction of the tip 8a-c does not cause the actuator 50 moves toward the direction indicator 22, the indicator 22 does not cause teeth 60 engaging the engagement by the indicator. 由此,使用者可以多次地拔出以及插入端头而不会减小指示器22。 Accordingly, the user can repeatedly pulled out and inserted into the tip 22 without decreasing the indicator. 当机械撞杆40被压入时,凸缘46靠近偏置弹簧接触构件96,导致偏置弹簧48的压缩。 When the mechanical striker 40 is pressed in, the flange 46 and close the contact member biasing spring 96, resulting in the biasing spring 48 is compressed. 偏置弹簧48的压缩导致一个偏置力作用在凸缘46上,该力的方向背离偏置弹簧接触构件96,只要电外科器械1从电外科电源(未示)拔下,该力就会迫使机械撞杆40回复到其伸出位置。 Compression biasing spring 48 causes a biasing force on the flange 46, facing away from the direction of the biasing force of the spring contact member 96, as long as the electrosurgical instrument is unplugged from an electrosurgical power source (not shown), this force will mechanical forcing lance 40 returns to its extended position.

随着多次消毒/使用循环的进行,指示器22将沿电源线4的方向逐步地移动。 With multiple sterilization / use cycle, the indicator 22 will move in the direction of the power supply line 4 stepwise. 随着指示器22沿电源线4的方向进一步地移动,一个或多个标记24显示出来,为使用者指示剩余的消毒/使用循环的次数。 As the indicator 22 along the direction of the power supply line 4 is further moved, one or more marker 24 is displayed, indicating to the user the number of remaining sterilization / use cycle. 如本领域内的技术人员所理解的那样,可采用多种类型及构造的闭锁机构而不会偏离本发明的范畴及精神。 As those skilled in the art appreciate, the locking mechanism can be a variety of types and configurations without departing from the scope and spirit of the invention.

如上文所述,在图1-4B所示的实施方式中,指示器22包括爪簧30,该爪簧30使得指示器22一致地减小。 As described above, in the embodiment shown in FIGS. 1-4B, the indicator 22 includes a pawl spring 30, the pawl spring 30 so that the indicator 22 is reduced uniformly. 爪簧30包括弹性的臂31,该臂31保持爪簧30的爪簧接合齿32与紧固构件34的齿之间的接触。 A pawl spring 30 includes a resilient arm 31, the arm 31 is held in contact between the teeth 32 and 34 of the fastening member 30 of the pawl spring engages pawl spring. 在图3B中,爪簧接合齿32处于一组齿之间,该组齿紧跟在图3A中爪簧接合齿32所处的那组齿之后。 Set of teeth 3B, the pawl spring 32 is engaged between teeth of a set of teeth, keeping the set of teeth which engage the teeth 32 in FIG. 3A after the pawl spring. 原因是因为:电外科器械1已经经历了第一次使用循环,该循环导致指示器22移动。 The reason is because: the electrosurgical instrument has been subjected to a first time cycle, which causes movement of the pointer 22.

如上所述,爪簧30包括弹性臂31,该弹性臂保持爪簧接合齿32与紧固构件34的齿之间的接触。 As described above, the pawl spring 30 includes a resilient arm 31, the resilient arm to maintain contact between the teeth 32 and 34 of the fastening member engaging pawl spring. 随着指示器22减小,通过致动器50而作用在指示器22上的力导致爪簧接合齿32的移动。 Decreases indicator 22, the indicator 50 acting on the actuator 22 by the spring force causes the pawl 32 engages the teeth of the mobile. 爪簧接合齿32与紧固构件34之间的接合防止指示器22的移动,直至通过撞杆40以及致动器50在指示器22上作用的力超过一个阈值。 Pawl spring engagement tooth 32 engages with the fastening member 34 to prevent movement between the indicator 22 until the lance 40 through the actuator 50 and the force acting on the indicator 22 exceeds a threshold value. 这使得在不曾有意地压入撞杆40时指示器22非期望地移动的可能性最小。 This makes it never intentionally pushed into the lance 22 minimizes the possibility of undesired movement of the pointer 40. 对撞杆40的有意压入——例如当将端头8a-c插入到电外科电源(未示)内时产生——足够地大而超出了移动爪簧接合齿32使之脱离处于紧固构件34第一组齿之间的位置、越过该组齿中的一个齿、并进入到处于第二组齿之间的位置所需的力的阈值。 It intends to lance 40 is pressed - for example, when generated in the tip 8a-c is inserted to the electrosurgical power source (not shown) - large enough to move beyond the teeth of pawl spring 32 disengaging it from engagement in fastening a position between the teeth 34 of the first group of components, over one tooth of the set of teeth, and into the desired position at the threshold between the teeth of the second set of forces. 此外,紧固构件34的齿的构造防止爪簧接合齿32朝近向移动,而允许爪簧接合齿32朝远向的移动。 Further, the configuration of the teeth of the fastening member 34 engages the teeth to prevent the pawl spring 32 moves toward the near, to allow movement of the teeth engaging pawl spring 32 toward the distal direction.

通过使得爪簧接合齿32在机械撞杆40两次压入之间行进限定的距离,爪簧30、爪簧接合齿32、以及紧固构件34还使指示器保持正确地减小。 By making the pawl spring 32 engages the teeth 40 between two mechanically pressed lance defined distance traveled, the pawl spring 30, the pawl spring 32 engages the teeth, and a fastening member 34 to maintain properly the indicator further reduced. 如本领域内的技术人员所理解的那样,可采用多种类型及构造的机构来使得指示器的非期望运动最小化而不会偏离本发明的范畴与精神。 As those skilled in the art appreciate, it may take a variety of mechanisms and structure types such undesired movement of the indicator to be minimized without departing from the scope and spirit of the invention.

转向图3D,其示出了在电外科器械1使用之后、但在随后的消毒循环之前当机械撞杆40部分地从壳体2伸出时致动器50的操作。 Turning to Figure 3D, which illustrate an electrosurgical instrument after use, but when the machine prior to the subsequent sterilization cycle operation of the actuator 40 protrudes from the housing portion 250 of lance. 图3D示出了:当指示器22的充分地移动以向使用者指示电外科器械已经被使用过一次时电外科器械1内部部件的位置。 FIG. 3D shows: when the indicator 22 is moved sufficiently to indicate to a user of the electrosurgical instrument has been used once the position of the inner member 1 electrosurgical instrument.

如图所示,弹簧80邻近致动器50以及机械撞杆40设置。 As shown, the spring 80 adjacent the actuator 50 and a mechanical striker 40 is provided. 弹簧80构造成保持计数器/闭锁机构10的部件正确地工作。 Spring member 80 is configured to hold counter / lockout mechanism 10 is operating correctly. 弹簧80的第一端82与致动器50的突起52接触。 The first end 82 of the spring 80 and the protrusion 52 contacts the actuator 50. 当机械撞杆40不再处于指示器接合齿60与指示器22的齿26之间时,弹簧80将致动器50的突起52朝指示器22的方向偏置。 When the lance 40 between the mechanical indicator is no longer in engagement with the teeth 60 of the indicator 22 teeth 26, the spring 80 of the actuator 50 in the direction 52 toward the projection 22 of the pointer offset. 在一个实施方式中,对致动器50的偏置能够促使指示器接合齿60与指示器22的齿26接合。 In one embodiment, the bias of the actuator causes the indicator 50 can engage teeth 60 and 22 engage the teeth 26 pointer. 在另一个实施方式中,需要致动温度致动元件70来使得指示器接合齿60与指示器22的齿26接合。 In another embodiment, the required temperature of the actuator the actuating member 70 to engage the teeth 60 so that the indicator 22 of the indicator 26 engages.

当指示器22不处于远端方向最大的移位时,指示器22在邻近远端44处接触机械撞杆40的至少一个部分的,并沿该部分一侧提供横向支撑,为弹簧80的第二端84提供一个反作用力。 When the indicator 22 is not in the distal direction of maximum displacement, the pointer 22 at the contact lance 44 adjacent the distal end 40 of the mechanical portion of at least one, and provide lateral support along one side of this portion, the spring 80 a second end 84 to provide a reaction force. 弹簧80的第二端84以及指示器22的反作用力控制机械撞杆40的横向移动。 The second end 84 of the indicator 22 and the reaction force spring 80 controlling the mechanical lateral movement of the lance 40. 在所示的实施方式中,机械撞杆40的远端44略微地厚于机械撞杆40的其它部分。 In the embodiment shown, the distal end 44 of mechanical lance 40 is slightly thicker than other portions of the machine 40. The ram. 远端44的截面厚度如此地选择:远端44比齿26与致动接合构件90之间的间隙要宽,使得致动接合构件90的内表面(即面对着撞杆40的那个表面)防止机械撞杆40的远端44越过致动接合构件90。 The distal end 44 of the cross-sectional thickness so selected: a gap between the distal end 44 of the member 90 than the tooth 26 engages with the actuator to be wider, such that the actuating member 90 engage the inner surface (i.e. facing surface 40 of the lance) preventing the distal end 40 of the lance 44 beyond the mechanical actuating member 90 engages.

转向图4A,其示出了电外科器械1在致动温度致动元件70之后、但在一系列消毒/使用循环后的内部俯视图。 Turning to Figure 4A, which shows an electrosurgical instrument after actuation temperature of the actuating element 70, but within the range of sterilization / use cycle plan view. 当被致动时,温度致动元件70将致动器50回复到这样的一个位置上:其中指示器接合齿60再次与指示器22的齿26接合。 When actuated, the temperature of the actuating member 70 to the actuator 50 return to such a position: wherein the indicator engaging teeth 60 engage the teeth 22 of the indicator 26 again. 对温度致动元件70的致动为指示器22的减小作好了准备。 The temperature of the actuating member 70 of the actuator ready for the indicator 22 decreases. 在所示的实施方式中,温度致动元件70与致动器50接合,使得在被致动后温度致动元件70保持非直线型构形。 In the illustrated embodiment, the temperature of the actuating member 70 engages the actuator 50, so that the temperature of the actuator is actuated member 70 holding the non-linear configuration. 通过保持非直线型构形,当需要压入机械撞杆40时,温度致动元件70阻止机械撞杆40的被压入的可能性减小。 By maintaining non-linear configuration, when pressed into the required mechanical striker 40, the temperature of the actuating member 70 to prevent the possibility of mechanical lance 40 is pressed into reduced.

在图4A中,温度致动元件70包括形状记忆合金——例如但不限于Nitinil。 Such as, but not limited to Nitinil - in Figure 4A, the temperature of the actuator element 70 comprises a shape memory alloy actuator. 当温度致动元件70受到足够的温度时,其回复到初始的形状并且是刚性的且不易于弯曲。 When the temperature of actuating member 70 by a sufficient temperature, it returns to its original shape and is rigid and not easily bent. 从而,当电外科器械1经历一次消毒循环,则温度致动元件70从一个弯曲的位置(图3C)转变成一个更为直线型的构形,如图4A所示。 Thus, when an electrosurgical instrument undergoes a sterilization cycle, the temperature of the actuating member 70 from a bent position (FIG. 3C) into a more rectilinear configuration shown in Figure 4A. 温度致动元件70更为直线型的构形由温度致动元件70的刚化而引起。 The temperature of the actuating member 70 is more rectilinear configuration by the temperature of the actuating member 70 has just caused. 温度致动元件70的刚化沿端头8a-c的方向推动致动器50,直至销58与凸轮槽56的远端接触。 Temperature-actuated in the direction of the rigid tip 8a-c element 70 pushes the actuator 50, until the pin 58 in contact with the distal end of the cam groove 56. 这导致致动器50相对于指示器22移位。 This causes the actuator 50 with respect to the displacement indicator 22.

参照图2和4A,温度致动元件70位于一个座76中,所述座76形成于电外科器械1的壳体2内。 Referring to FIGS. 4A and 2, the temperature of the actuating member 70 is located in a seat 76, within the seat 76 of the housing 1 is formed on the electrosurgical instrument 2. 温度致动元件70的远端74与座76接合而防止温度致动元件70的远端74沿电源线4的方向移动。 The temperature of the distal end 70 of the actuating member 74 engages the seat 76 and prevent the temperature of the distal end of the actuating member 70 is moved in the direction 74 of the power supply line 4. 温度致动元件70的近端72与致动器50在槽64处接合,该槽(可在图2中最好地看到)形成于致动器50的侧部内。 The temperature of the actuating member 70 proximal end 72 of the actuator 50 engages the groove 64 at the groove (best seen in FIG. 2) formed in the side portion 50 of the actuator.

当温度致动元件70被加热到一个预定的温度时(例如在消毒过程中),温度致动元件70的刚度增加、强度增加、而柔度减小。 When the temperature of actuating member 70 is heated to a predetermined temperature (e.g., during sterilization), the temperature of the actuating member 70 to increase the stiffness, increasing strength, and the flexibility decreases. 温度致动元件70的刚化减小了温度致动元件70的曲率。 The temperature of the actuating element 70 stiffening curvature reduces the temperature of the actuating member 70. 当温度致动元件70受到足够的加热时,其从大致弯曲的构形(图3C)转变成更为直线型和刚性的构形,导致近端72沿端头8a-c的方向推动致动器50,如图4A所示。 When the temperature of actuating member 70 by sufficient heating, which transition from a substantially curved configuration (FIG. 3C) into a more linear configuration and rigidity, resulting in the first direction along the end 72 of the proximal end 8a-c push the actuator 50, shown in Figure 4A.

在图4A中,温度致动元件70提供一个推动而移动致动器50。 In Figure 4A, the temperature of the actuating member 70 to provide a push actuator 50 is moved. 通过利用这个推动,温度致动元件70降低了计数器/闭锁机构10的制造成本及复杂程度,同时提高了系统的可靠度。 By using this pushing, the temperature of the actuating member 70 to reduce the manufacturing cost and complexity of the counter / lockout mechanism 10, while increasing the reliability of the system. 原因在于:温度致动元件70的刚化有效地移动了致动器50而不需要精确地制造温度致动元件70的尺寸、厚度、以及长度。 The reason is that: the temperature of the actuating member 70 is effective to move the rigidifying actuator 50 without requiring precise manufacture of the temperature of actuating member 70 the size, thickness, and length. 这降低了温度致动元件70的设计和制造成本。 This reduces design and manufacturing costs of the temperature of the actuating member 70. 此外,温度致动元件70不需要一体地耦合到计数器/闭锁机构10的其它部件以保持在拉型致动设备中所需要的公差。 In addition, the temperature of the actuating member 70 does not need to be integrally coupled to the other components of the counter / lockout mechanism 10 to maintain a tolerance pull-type actuator apparatus required. 相反地,在组装期间,温度致动元件70可容易地设置在座76和槽64内(视图2),极大地减小了计数器/闭锁机构10的组装复杂度、费用以及困难程度。 Conversely, during assembly, the temperature of the actuating member 70 can be easily disposed inside the seat 76 and 64 (Figure 2) groove, the assembly greatly reduces the complexity, cost and difficulty of counter / lockout mechanism 10. 如本领域内的技术人员所理解的那样,可采用多种类型和构造的致动元件而不会偏离本发明的范畴及精神。 As those skilled in the art appreciate, it may take a variety of types and configurations of actuating element without departing from the scope and spirit of the invention. 在一个实施方式中,温度致动元件构造成提供一个拉力,从而导致指示器的正确致动。 In one embodiment, the temperature of the actuating element is configured to provide a force, resulting in the correct actuation of the indicator.

继续参考图4A,由于指示器22的齿26以及致动器50的指示器接合齿60的构造,致动器朝端头8a-c方向的移动并不会导致指示器22的移动。 With continued reference to Figure 4A, the teeth 26 since the indicator 22 and the indicator actuator 50 is configured to engage the teeth 60, movement of the actuator toward the tip 8a-c and the direction of movement of the pointer 22 does not result. 此外,温度致动元件70的重复加热和冷却不会导致计数器的多次减小,因为指示器22的移动仅响应于机械撞杆40的压入而发生。 In addition, the temperature of the actuating member 70 was repeated heating and cooling times does not cause decrease of the counter, because the movement of the indicator 22 only in response to the mechanical press 40 of lance occurs. 由此,致动器50不会导致一个或多个标记24的改变,直至温度致动元件70经历了消毒循环且沿一个方向移动致动器50、而机械撞杆40经历了由撞杆的压入而指示的使用循环且沿相反的方向移动致动器50。 Thus, the actuator 50 does not result in one or more markers 24 are changed until the temperature of the actuating member 70 undergoes a sterilization cycle in one direction and movement of the actuator 50 and the mechanical striker 40 is experienced by the lance press fitting using a loop instruction and the movement of the actuator 50 in the opposite direction.

图4B为电外科器械1的内部俯视图,其示出了在消毒循环之后的电外科器械1不同内部部件的位置,该电外科器械已经超出了所推荐的消毒次数。 FIG 4B is a plan view of the interior of the electrosurgical instrument of Figure 1, which shows the position of various internal components after sterilization cycles electrosurgical instrument 1, the electrosurgical instrument has exceeded the number of times the recommended disinfection. 如图所示,弹簧80以及指示器22配合地将机械撞杆40紧固在一个伸出的位置上。 As shown, the spring 80 and an indicator 22 fitted to the lance 40 mechanically secured in position on a projecting. 在所示的实施方式中,指示器22已经完成了其最后的减小,并且不再与机械撞杆40的远端44接触。 In the embodiment shown, the indicator 22 has completed its final reduced, and no longer in contact with the distal end 40 of the rod 44 with mechanical striker. 当指示器22不再与机械撞杆40的远端44接触时,其不再为弹簧80的第二端84提供横向支撑、并且不再提供一个反作用力来阻止弹簧80的第二端84。 When the indicator 22 is no longer in contact with the distal end 40 of the rod 44 with mechanical striker, which no longer provide lateral support to the second end 84 of the spring 80, and a second end 84 is no longer provided to prevent a reactive force of the spring 80. 由此,弹簧80的第二端84接触机械撞杆40的远端44并将之偏置入指示器22的闭锁部分28。 Thus, the second end 84 of the spring 80 contacts the striker 44 and the mechanical biasing of the distal end of the rod 40 into the closure portion 28 of the indicator 22. 这使得远端44越过致动接合构件90,并允许机械撞杆40移动到一个完全伸出的闭锁位置,如图4B所示。 This allows the distal end of the actuator 44 beyond the engaging member 90, and allows a fully extended position of the mechanical locking lance 40 to move, shown in Figure 4B.

机械撞杆40通过偏置弹簧48而被移动到完全伸出的位置。 40 is moved to a position fully extended by the biasing spring 48 is a mechanical striker. 在偏置弹簧48将机械撞杆40移动到完全伸出的位置之前,偏置弹簧48压缩于凸缘46和偏置弹簧接触构件96之间。 In a mechanical biasing spring 48 striker 40 before moving to the fully extended position, the biasing spring 48 is compressed between the flange 46 and the bias spring contact member 96. 凸缘46不能移动地耦合到机械撞杆40。 Flange 46 immovably coupled to mechanical striker 40. 偏置弹簧构件元件96一体地耦合到壳体2的下部。 Member biasing spring element 96 is integrally coupled to the lower housing 2.

当闭锁部分28位于致动接合构件90附近时,弹簧80的第二端84沿横向偏置机械撞杆40的远端44。 When the latch portion 28 is located near the engagement actuation member 90, the second end 84 of the spring 80 is laterally offset along the distal end 40 of mechanical lance 44. 这提供了致动接合构件90与指示器22之间的额外的距离,从而使得致动接合构件90与指示器22之间的距离大于机械撞杆40远端44的宽度。 This provides an additional 90 with the distance between the indicator member 22 engages the actuator, so that the distance 22 between the member 90 and the indicator actuator 40 engages the distal end 44 is greater than the width of the mechanical striker. 由此,致动接合构件90不再以提供偏置弹簧48在凸缘46上的反作用力的方式与机械撞杆40的远端44接触。 Thereby, the actuating member 90 is no longer engaging the biasing spring 48 so as to provide a reaction force on the flange 46 and distal end 44 of mechanical contact lance 40. 当不存在因与致动接合构件90接触而提供的反作用力时,通过偏置弹簧48作用在凸缘46上的力导致机械撞杆40朝近向的移动。 When the reaction force due to the contact with the actuating member 90 does not exist to provide engagement by the force of biasing spring 48 acting on the flange 40 is moved toward the lead 46 near the mechanical striker. 在本发明的一个实施方式中,偏置弹簧接触构件以及致动接合构件与壳体的下部一体地形成。 In one embodiment of the present invention, the biasing spring engages the contact actuating member and the lower member is integrally formed with the housing. 在可选的实施方式中,偏置弹簧接触构件以及致动接合构件不能移动地固定到壳体2的一个或多个部分上。 In an alternative embodiment, the biasing spring and the contact actuating member engaging member immovably fixed to one or more portions of the housing 2.

在所示的实施方式中,当凸缘46与壳体2的内表面接触时,机械撞杆40的近向移动停止。 In the embodiment illustrated embodiment, when in contact with the inner surface of the flange 46 of the housing 2, the lance 40 near the mechanical stops moving. 当凸缘46与壳体2的内表面接触时,机械撞杆40从壳体2中完全地伸出。 When the flange 46 in contact with the inner surface of the housing 2, the lance 40 extends entirely mechanically from the housing 2. 弹簧80的第二端84与指示器22接触而将机械撞杆40紧固在伸出的位置中。 The second end 84 of the spring 80 is in contact with the indicator 22 and the mechanical fastening of the lance 40 in the extended position. 指示器22处于其最大的远向移位位置上,并与止挡25接触。 Indicator 22 is in its maximum displacement position on the far, and in contact with the stopper 25. 止挡25由壳体2的下部形成。 The stopper 25 is formed by the lower housing 2. 止挡25防止指示器22进一步地后向移位。 The stopper 25 prevents the indicator 22 further to the shift.

指示器22、第二端84、以及机械撞杆40的远端44防止机械撞杆40被压入。 Indicator 22, a second end 84, a distal end 40 and a mechanical striker 44 of lance 40 is prevented from mechanically pressed. 在所示的位置上,机械撞杆40从壳体最大地移位。 In the position shown, lance 40 mechanically displaced maximally from the housing. 通过防止机械撞杆40被压入,防止了端头8a-c与电源(未示)的接合。 By preventing mechanical striker 40 is press-fitted, prevents the tip 8a-c power supply (not shown) engaged. 由此,一旦完成了预定次数的消毒/使用循环之后,计数器/闭锁机构10阻止使用者使用电外科器械1。 Thus, once the completion of a predetermined number of sterilization / use cycle, counter / lockout mechanism 10 prevents the user from using the electrosurgical instrument 1. 在所示的实施方式中,爪簧接触齿32位于紧固构件34的最后一组齿之间。 In the embodiment illustrated embodiment, the contact between the teeth of pawl spring 32 is located in the fastening member 34 of the last set of teeth. 这是由于:电外科器械1已经经历了预定次数的消毒/使用循环,且指示器22位于其最远的移位位置上。 This is because: the electrosurgical instrument has been subjected to a predetermined number of sterilization / use cycle, and the indicator 22 is in its position displaced furthest.

如本领域内的技术人员所理解的那样,可采用多种类型及构造的闭锁机构而不会偏离本发明的范畴与精神。 As those skilled in the art appreciate, the locking mechanism can be a variety of types and configurations without departing from the scope and spirit of the invention. 例如,在一个实施方式中,闭锁机构采用包括片簧的横向偏置机构。 For example, in one embodiment, the locking mechanism comprises a biasing mechanism using a transverse leaf spring. 在另一个实施方式中,闭锁机构采用不包括片簧的横向偏置机构。 In another embodiment, the latching mechanism that does not include a transverse leaf spring biasing mechanism. 在另一个实施方式中,闭锁机构不采用横向偏置机构。 In another embodiment, the latching mechanism does not employ a lateral biasing mechanism. 在又一个实施方式中,闭锁机构不包括闭锁部分。 In yet another embodiment, the latching mechanism includes a latch portion is not.

图5为电外科器械100的内部视图,其示出依据本发明另一实施方式的计数器/闭锁机构110。 5 is an interior view of the electrosurgical instrument 100, which is shown according to another embodiment of the invention the counter / lockout mechanism 110. 为了帮助解释电外科器械100和计数器/闭锁机构110的结构及功能,在图5-9中不曾示出从电源线104直到端头108a-c的电线或者其它的电气连接设备。 To help explain the structure and function of the electrosurgical instrument 100 and a counter / lockout mechanism 110, shown in FIG. 5-9 did not from the power supply line 104 until the tip 108a-c of the wire or other electrical connection devices.

在所示的实施方式中,计数器/闭锁机构110包括指示器122、致动器150、温度致动元件170、以及机械撞杆140。 In the illustrated embodiment, the counter / lockout mechanism 110 includes an indicator 122, actuator 150, the temperature of the actuating member 170, and a mechanical striker bar 140. 温度致动元件170和机械撞杆140配合地使致动器150沿第一和第二方向移动。 The temperature of the actuating member 170 fit mechanical ram 140 of the actuator 150 and moves along the first and second directions. 这使得致动器150可以移动指示器122并实现一个或多个标记的改变,从而示出消毒/使用循环已经结束。 This allows the actuator 150 may move the pointer 122 and effect a change in one or more markers, thereby showing sterilization / use cycle has ended.

在所示的实施方式中,温度致动元件170是形状记忆合金——例如、但是并不限于Nitinol。 In the illustrated embodiment, the temperature of the actuating member 170 is a shape memory alloy - for example, but not limited to Nitinol. 当温度致动元件170处于足够的温度下时,其回复到初始的形状并且是刚性的,不易于弯曲。 When the temperature of the actuating member 170 is at a sufficient temperature, it returns to its original shape and is rigid and difficult to bend. 从而,当电外科器械100经历一次消毒循环时,由于温度致动元件170变硬,温度致动元件170从一个所示的弯曲位置变化成更呈直线型的构形(如图8所示)。 Thus, when the electrosurgical instrument 100 undergoes a sterilization cycle, since the temperature of the actuating member 170 hardens, the temperature of the actuating member 170 is bent from the position shown in the form of a change to a more linear configuration (as shown in FIG. 8) . 温度致动元件170的变硬将致动器150推往端头108a-c的方向。 Hardening temperature of the actuator element 170 of the actuator 150 pushes the direction of the tip 108a-c to. 这导致致动器150相对于指示器122移位。 This causes actuator 150 with respect to the displacement indicator 122.

温度致动元件170为用来探测高于室温的温度的装置的一个示例。 The temperature of the actuating element 170 is used as an example of a temperature above room temperature detecting means. 可采用多种类型及构造的用来探测高于室温的温度的装置而不会偏离本发明的范畴和精神。 Can be a variety of types and configurations means for detecting a temperature above room temperature without departing from the scope and spirit of the invention. 例如,在一个实施方式中,可采用这样的一个温度致动元件:其磁性可随温度变化。 For example, in one embodiment, such a temperature may be employed actuating element: its magnetic properties can vary with temperature. 在另一个实施方式中,可采用这样的一种温度致动元件:其包括一个响应温度波动的液体部分或者填充有液体的部分。 In another embodiment, such a temperature may be employed actuating element: in response to temperature fluctuations which comprises a portion of the liquid or partially liquid filled.

在消毒循环之后,当使用者意图使用电外科器械100时——例如通过将端头108a-c插入到电外科出口(未示),机械撞杆140的近端将被接触并被推入到壳体102的内部。 After the sterilization cycle, when the user intends to use electrosurgical instrument 100-- example will be contacted by the tip 108a-c is inserted to the electrosurgical outlet (not shown), the proximal end 140 of the machine and pushed into the striker lever the interior of the housing 102. 致动器150环绕一部分的机械撞杆140。 Mechanical actuator 150 surrounds a portion of the ram 140. 机械撞杆140位于致动器150内部的部分与致动器150的内表面接合。 Mechanical striker lever 140 is located inside of the actuator 150 and the actuator portion 150 engages the inner surface. 由此,当机械撞杆140沿电源线104的方向移动时,致动器150沿电源线104的方向移动。 Thus, when the moving direction of the lance 140 along the mechanical power supply line 104, the moving direction of the actuator 150 along the power line 104. 换句话说,当机械撞杆140被迫入壳体102内时,致动器150被推向电源线104的方向。 In other words, when the mechanical forced into the lance 140 within the housing 102, the actuator 150 is pushed toward the direction of the power line 104. 当致动器150被推向电源线104的方向时,致动器150与指示器122的互补表面相接合的表面导致指示器122沿电源线104的方向移动。 When the actuator 150 is pushed toward the direction of the power line 104, the complementary surface of the actuator 150 and the indicator 122 engages a surface 122 results in the moving direction of the pointer 104 along the power line. 指示器122的移动使得标记的位置改变,从而指示消毒/使用循环已经结束。 Movement of the pointer 122 causes the change in position of the marker, indicating that the disinfection / use cycle has ended. 这还导致电外科器械100剩余的使用次数减小。 This also leads to the electrosurgical instrument 100 decreases the residual number of uses.

当外力不再作用在机械撞杆140的近端上时,偏置弹簧可以使得机械撞杆140从壳体2伸出。 When an external force does not act on the proximal end of a mechanical ram 140, biasing spring 140 may be such that the lance extends from the machine casing 2. 这导致机械撞杆140的近端从壳体2伸出。 This causes the proximal end 140 of the mechanical housing 2 protrudes from the lance. 然而,致动器150不朝端头108a-c方向移动,直至温度致动元件170响应于消毒循环而被致动。 However, the actuator 150 is not toward the tip 108a-c direction, until the temperature of the actuating member 170 in response to the sterilization cycle is actuated. 由此,机械撞杆140的进一步的压入不会导致致动器150以及指示器122移动,直至进行了随后的消毒循环。 Accordingly, a further mechanical press ram 140 does not cause the actuator 150 and an indicator 122 is moved, until the subsequent sterilization cycles carried out. 机械撞杆140为一个探测使用循环的装置的一个示例。 Mechanical striker lever 140 is one example of a detecting means for circulating used. 对于本领域内的技术人员而言,其它的探测装置是已知的。 For those skilled in the art, other detection means are known. 例如用于后续使用的钥匙的可移除的撞针、以及带有芯片的软件、电光源、条线图可用作探测使用循环的装置。 For example, a key for subsequent use striker removable, and software with chips, electric light, the bar graph may be used as means for detecting use cycles.

图6A和6B为电外科器械100的局部剖视图,其示出电外科计数器/闭锁机构110的部件、以及温度致动元件170和机械致动元件(即机械撞杆140)与致动器170的一种联接方式(视图6B)。 6A 6B is an electrosurgical instrument partial sectional view and 100, which illustrates electrosurgical counter means / locking mechanism 110, and the temperature of the actuating member 170 and a mechanical actuator member (i.e., a mechanical ram 140) and the actuator 170 one kind of connection mode (view 6B). 在图6A所示的实施方式中,温度致动元件170位于座176中——该座形成于电外科器械100的壳体102中。 In the embodiment shown in FIG. 6A, the temperature of the actuating member 170 is located in the seat 176 - 102 formed on the seat housing 100 of the electrosurgical instrument. 温度致动元件170的远端174与座176接合而防止温度致动元件170沿电源线104的方向移动。 The temperature of the distal end 174 of the seat 176 of the actuating member 170 engages the actuator to prevent the temperature of the power supply line 104 along the direction 170 of the mobile element. 温度致动元件170的近端172与致动器150接合(未示)。 The temperature of the actuating member 150 engages the proximal end 170 of the actuator 172 (not shown).

当温度致动元件170的温度升高时(例如在消毒过程中),温度致动元件170刚度和强度增加,而温度致动元件170的柔度减小。 When the temperature of the actuating member 170 is elevated temperatures (e.g., during sterilization), the temperature of the actuating member 170 to increase stiffness and strength, flexibility and the temperature of the actuating member 170 is reduced. 温度致动元件170的刚化减小了温度致动元件170的曲率。 The temperature of the actuating member 170 is reduced stiffening curvature of the temperature of the actuating member 170. 当温度致动元件170被足够地加热时,其从大致弯曲的构形改变成更为直线型和刚性的构形,其中近端172朝端头108a-c的方向推动致动器150。 When the temperature of the actuating member 170 is sufficiently heated, it changed from a generally curved configuration to a more rigid and straight configuration, wherein the proximal end 172 in the direction 108a-c of the push actuator 150.

通过利用推运动,温度致动元件170降低了闭锁机构110的制造费用以及复杂程度,同时提高了系统的可靠性。 By using push motion, the temperature of the actuating member 170 reduces the manufacturing costs and the complexity of the latching mechanism 110, while increasing the reliability of the system. 这是由于:温度致动元件170的刚化有效地移动了致动器150而不需要精确地制造温度致动元件的尺寸、厚度、以及长度。 This is because: the temperature of the actuating member 170 is effective to move the rigidifying size actuator 150 without the need for precisely manufactured actuating element temperature, thickness, and length. 这降低了温度致动元件170的设计和制造成本。 This reduces design and manufacturing costs of the temperature of the actuating member 170. 此外,温度致动元件170不需要一体地耦合到计数器/闭锁机构110的其它部件来保持拉型致动设备中所需要的公差。 In addition, the temperature of the actuating member 170 does not need to be integrally coupled to other components of the counter / lockout mechanism 110 to maintain the pull-type actuator apparatus required tolerances. 相反地,温度致动元件170可设置在座176内,极大地降低了计数器/闭锁机构110的组装复杂度、费用以及困难程度。 Conversely, the temperature of the actuating member 170 may be disposed within the seat 176, greatly reducing assembly complexity, cost and difficulty of counter / lockout mechanism 110.

在所示的实施方式中,撞杆140的近端142位于电外科器械100的壳体102之外。 In the embodiment shown, the proximal end of the lance is located in an electrical housing 142 140 102 100 outside the instrument. 撞杆140的远端144适于位于致动器150的内部(视图6B)。 The distal end 144 of the lance 140 adapted to be located inside of the actuator 150 (the view 6B). 机械撞杆140的远端144与致动器150接合,从而在机械撞杆140被压入时导致致动器150移动。 Mechanical ram 144 and the distal end 150 of actuator 140 engages, so that the mechanical striker lever 140 is pressed inward movement of the actuator 150 results in actuation. 机械撞杆140的接合脊145(视图6B)与接合构件190接合,该接合构件190耦合到电外科100的壳体102。 Mechanical lance engaging ridges 145 (view 6B) engaged with the engaging member 190 is 140, the engaging member 190 is electrically coupled to the housing 102 Surgery 100. 接合构件190防止接合脊145在端头108a-c的方向上运动越过一个给定的位置。 The engagement member 190 engages the ridges 145 to prevent movement in the direction of the tip 108a-c across a given position. 由此,机械撞杆140的近端142沿端头108a-c方向的运动不能越过一个给定的位置。 Thereby, a mechanical ram 142 along the proximal end 140 of the tip 108a-c can not cross the direction of motion of a given position.

偏置弹簧148环绕撞杆140的一部分,从而位于撞杆140的凸缘146和接合构件190之间。 140 biasing spring 148 surrounds a portion of the lance is located so that the striker flange 146 between the lever 140 and the engaging member 190. 偏置弹簧148提供一个沿端头108a-c方向的偏置力,以在机械撞杆140没有通过与壁装电源插座、插座、或者其它障碍物的接触而被压入时将机械撞杆140的近端142推出壳体102外。 A biasing spring 148 provided along the tip 108a-c direction biasing force to the ram 140 is not mechanically through a wall outlet, socket, or other obstructions while the contact is pressed in the mechanical striker 140 the proximal end 142 of outer housing 102 Release. 当机械撞杆140被压入时,远端144朝电源线104的方向移动。 When the mechanical striker lever 140 is pushed, the distal end 144 moves in the direction of the power supply line 104. 远端144与致动器150的内表面相互作用(视图6B),从而朝电源线104的方向移动致动器150。 The distal end of the actuator 144 and the inner surface 150 of the interaction (the view 6B), so as to move toward the direction of the power line 104 of the actuator 150. 如本领域内的技术人员所理解的那样,可采用多种类型及构造的机械撞杆而不偏离本发明的范畴与精神。 As those skilled in the art appreciate, it can be a variety of types and configurations without departing from the mechanical striker scope and spirit of the invention. 例如,在一个实施方式中,机械撞杆可在没有外部压力作用时保持压入。 For example, in one embodiment, the lance may remain mechanically pressed in the absence of external pressure.

为了简便以及更清晰地示出计数器/闭锁机构部件的操作,图6B示出致动器150与计数器/闭锁机构的几个部件分开。 For simplicity and more clearly illustrate the operation of the counter / lockout mechanism part, FIG. 6B shows the actuator member 150 with several separate counter / lockout mechanism. 在所示的实施方式中,致动器150包括体部152、槽道154、以及齿156。 In the illustrated embodiment, the actuator 150 includes a body portion 152, channel 154, and teeth 156. 体部152保持致动器150的刚度及结构,并提供足够的强度来移动指示器122(当由温度致动元件170(参见视图6A)接合接合时)和机械撞杆140。 Body portion 152 and maintaining the rigidity of the structure of the actuator 150, and to provide sufficient strength to move the pointer 122 (when the temperature of the actuator element 170 (see view engagement. 6A)) 140 and a mechanical striker. 槽道154由体部152限定并适于容置机械撞杆140的远端144。 Channel 154 defined by body portion 152 and a distal end 140 adapted to receive a mechanical striker rod 144. 这保持住了致动器150的朝向、同时使得机械撞杆140远端144的横向移动最小化。 This hold toward the actuator 150 while allowing the mechanical movement of the lance 140 laterally distal end 144 is minimized. 齿156形成于致动器150的体部152内。 Teeth 156 formed in the body portion 152 of the actuator 150. 致动器150的齿156与指示器122的齿126接合。 The actuator 150 engages the teeth 156 with the teeth 126 of the indicator 122. 当致动器150朝后移动时,齿156以及齿126的构造使得指示器122朝后向移动。 When the actuator 150 is moved toward the teeth 156 and the teeth 126 is configured such that the pointer 122 toward the backward movement. 当致动器150朝前向移动时,齿156以及齿126的构造不会使得指示器移动。 When the actuator 150 to move forward, the teeth 156 and the teeth 126 is configured such that the pointer does not move.

回到图6A,指示器组件120包括有指示器122以及导引件129。 Back to Figure 6A, the indicator assembly 120 includes an indicator 122 and a guide member 129. 指示器122适于相对于电外科器械100的其它部件移动,用来指示已经完成了的消毒/使用循环的次数改变。 Indicator 122 is adapted relative to the other member of the electrosurgical instrument 100 is moved to indicate sterilization has been completed / to change the number of cycles used. 导引件129配合地接合指示器122,以使得指示器122的横向移动最小化、并且确保指示器122响应于致动器150的移动而平稳及有效地滑动。 Guide member 129 matingly engage the indicator 122, so that the lateral movement of the pointer 122 is minimized, and to ensure that the indicator 122 in response to movement of the actuator slide smoothly and effectively 150. 在所示的实施方式中,导引件129包括位于槽道内的高起的滑动件,该槽道形成于指示器122的底部内。 In the illustrated embodiment, the guide member 129 includes a sliding member in a raised channel, the channel formed in the bottom portion 122 of the indicator.

如本领域内的技术人员所理解的那样,可采用多种类型及构造的导引件而不会偏离本发明的范畴和精神。 As those skilled in the art appreciate, the guide member can be a variety of types and configurations without departing from the scope and spirit of the invention. 在一个实施方式中,导引件包括有多个防止指示器非期望地运动的齿(未示)。 In one embodiment, the guide member comprises a plurality of teeth to prevent (not shown) of the pointer movement undesirably. 在另一个实施方式中,有防滑的物质(未示)位于导引件的顶部和指示器的底面之间,以防止指示器的非期望移动。 In another embodiment, with a substance (not shown) positioned between the bottom surface of the top guide member and the indicator, the indicator is desired to prevent non-slip movement. 在另一个实施方式中,导引件包括有一个表面,该表面与指示器之间产生足够的摩擦接触,从而防止指示器的非期望移动,即任何不是由机械撞杆相对于致动器的移动而导致的移动。 In another embodiment, the guide member includes a surface, generating a sufficient frictional contact between the surface and the indicator, the indicator so as to prevent non-desired movement, i.e. not with respect to any of the mechanical actuator of the lance movement which led to the move.

齿126形成于指示器122中。 Teeth 126 formed on the indicator 122. 齿126与致动器150的齿156接合。 The teeth 126 of the actuator 150 engage the teeth 156. 在所示的实施方式中,齿126与齿156的构造使得:当致动器150朝端头108a-c方向移动时,致动器150相对于指示器122移位,而指示器122不移动。 In the embodiment shown, the teeth 126 of the teeth 156 is configured such that: when the mobile end of the actuator 150 towards the head 108a-c direction, the actuator 150 with respect to the displacement indicator 122, the indicator 122 does not move . 当致动器150朝电源线104方向移动时,响应于机械撞杆140的压入,致动器150的齿156与指示器组件120的齿126接合,并且朝电源线104的方向移动指示器122。 When the actuator 150 moves in the direction of the power supply line 104, in response to a mechanical press ram 140 into the actuator 150 the teeth 156 and the teeth 126 engage the indicator assembly 120 and moves the pointer toward the direction of the power line 104 122.

在一个实施方式中,朝端头方向移动致动器所需要的力远小于沿电源线方向移动致动器及指示器所需要的力。 In one embodiment, the direction toward the head end of the actuator force much smaller than the required actuation direction along the power line and the indicator actuator force required. 在另一个实施方式中,由温度致动元件所提供的用来移动致动器的力远小于机械致动元件所提供的用来移动致动器和指示器的力。 In another embodiment, the temperature of the actuating force of the actuator is provided for moving the element is much smaller than the mechanical actuator for moving the actuator member provided by a force actuator and indicator. 在所示的实施方式中,机械撞杆140在致动器150上施加一个力。 In the embodiment shown, the mechanical striker lever 140 exerts a force on the actuator 150. 然后,致动器150接合致动器122并传递移动致动器122所需要的力。 Then, the actuator 150 engages actuator 122 and the actuator moving force transmission required actuator 122. 将参照图7和8更详细地描述致动器150以及指示器122响应于消毒/使用循环的移动。 Movement of the actuator 150 and an indicator 122 in response to the disinfecting / use cycle will be described in more detail with reference to FIGS. 7 and 8.

指示器122进一步包括闭锁部分128。 Indicator 122 further includes a latch portion 128. 闭锁部分128包括一个空隙,该空隙适于在指示器122移动到靠近电源线104处时容置致动器150。 Latching portion 128 comprises a void, which void is adapted to move the pointer 122 is close to the power supply line 104 accommodating the actuator 150. 致动器150的移动使得机械撞杆140可相对于端头108a-c移向最近端,而闭锁部分128、致动器150、以及撞杆140的远端144的并接设置(juxtaposition)防止机械撞杆140的远端144移向电源线104。 Movement of the actuator rod 150 such that the mechanical striker 140 with respect to the tip 108a-c toward the nearest end, and the latching section 128, actuator 150, and a distal end 144 of the lance 140 and is then provided (juxtaposition) to prevent mechanical lance toward the distal end 144,140 of the power supply line 104.

图7示出电外科器械100的内部视图,其示出了指示器122响应于机械撞杆140移动所进行的移动——当比较图5和图7中指示器122的位置时。 Figure 7 shows an interior view of the electrosurgical instrument 100, which shows a mechanical indicator 122 in response to movement of the striker lever 140 moves performed - when comparing the position of FIG. 5 and FIG. 7 of the indicator 122. 在图7中,机械撞杆140被压入,从而使得机械撞杆140的整个长度都位于壳体102的内部。 In Figure 7, mechanical rod 140 is pushed into the striker, so that the entire length of the mechanical striker 140 are located inside the housing 102. 如上文所述,机械撞杆140的远端144(视图6B)接合致动器150。 As described above, the distal end 140 of the machine ram 144 (view 6B) engages the actuator 150. 这导致致动器150沿电源线104的方向移动。 This results in the moving direction of the actuator 150 along the power line 104. 当致动器150沿电源线104的方向移动时,致动器150的齿156接合指示器122的齿126。 When the moving direction of the actuator 150 along the power line 104, the actuator 150 of the teeth 156 engage the teeth 126 of the indicator 122. 这导致指示器122沿电源线104的方向移动。 This results in the moving direction of the pointer 122 along the power line 104. 当指示器122沿电源线104的方向移动时,标记改变了,为使用者显示在完成一次消毒/使用循环之后所剩余的使用次数。 When the pointer 122 moves in the direction of the power line 104, the flag changes, the number of displays for a user to use after completion of a sterilization / use cycle remaining. 此外,当致动器150沿电源线104的方向移动时,温度致动元件170回复到这样的构造:在在由机械撞杆140施加到致动器150上的力或影响的作用下,温度致动元件具有较大程度的曲率。 Further, when the moving direction of the actuator 150 along the power line 104, the temperature of the actuating member 170 to return to such a configuration: In the mechanical ram 140 is applied to effect actuation force or influence on the 150 actuator, temperature the actuating element having a large degree of curvature. 当温度致动元件170不承受导致温度致动元件170的刚度增加的温度时,温度致动元件170能够具有的所述较大程度曲率。 When the temperature of the actuating member 170 is not subjected to the temperature of the actuating member 170 results in the increased stiffness of the temperature, the greater degree of temperature-actuated element 170 can have a curvature. 由此,温度致动元件170提供了极小的阻力,使得近端172可以更靠近接合在座176内的远端174。 Accordingly, the temperature of the actuating member 170 provides minimal resistance, so that the proximal end 172 may be closer to the distal end of the engagement seat of 176,174.

当机械撞杆140被压入时,凸缘146移近接合构件190,导致偏置弹簧148的进一步压缩。 When the mechanical striker lever 140 is pushed, the engagement member 190 moves closer to flange 146, resulting in further compression of the biasing spring 148. 偏置弹簧148的压缩在凸缘146上施加了一个力,使得一旦相互作用力不再施加在机械撞杆140的近端142上时,近端142将从电外科器械100的壳体102伸出。 Biasing spring 148 exerts a compressive force on the flange 146, such that once the force is no longer applied in the mechanical interaction striker 142 on the proximal end 140, a proximal end 142 of the housing 102 from electrosurgical instrument 100 extending out. 一旦致动器150处于现在的位置时,将端头108a-c拔出并随后插入插口中将不会导致致动器150的额外移动。 Once the actuator 150 is in the current position, the tip 108a-c will be removed and then inserted into the socket does not cause additional actuation of the actuator 150 is moved. 这是由于:撞杆140远端可滑动地接合于致动器150内。 This is because: the distal end of the striker lever 140 is slidably engaged within the actuator 150. 机械撞杆140沿端头108a-c的运动不会导致致动器150沿端头108a-c方向的移动。 Mechanical lance 140 along the tip 108a-c does not result in movement of the actuator 150 is moved along the end head 108a-c direction. 由此,使用者可以多次地插入和拔出端头108a-c而不会使得指示器122减小。 Accordingly, the user can repeatedly inserted and removed tip 108a-c so that the indicator 122 will not be reduced.

图8示出电外科器械110处于消毒循环中。 8 illustrates an electrosurgical instrument in a sterile 110 cycles. 在所示的实施方式中,温度致动元件170从图7所示的弯曲构形变化到更为直线型的构形。 In the illustrated embodiment, the temperature of the actuating member from the bent configuration shown in FIG 7170 is changed to a more linear configuration. 更为直线型的构形是刚度增加的结构,该刚度增加的原因是在消毒循环期间的温度变化。 More rectilinear configuration is the increased structural stiffness, the cause of the increased stiffness is the temperature change during sterilization cycle. 所增加的刚度提供了这样的一个拉伸强度:其超出了温度致动元件170不承受高温时的拉伸强度。 The increased stiffness provides such a tensile strength: the tensile strength thereof exceeds the temperature of the actuating member 170 does not withstand high temperatures. 当处于更为直线型的构形时,温度致动元件170的近端172沿端头108a-c方向推动致动器150。 When in a more rectilinear configuration, the temperature of the actuating member 170 a proximal end 172 of the tip 108a-c along the direction of push actuator 150.

由于指示器122的齿126以及致动器150的齿的构造,致动器150沿端头108a-c方向的移动并不导致指示器122的移动。 Since the configuration of teeth 126 of the indicator 122 and an actuator 150, moves the actuator 150 along the tip 108a-c does not result in the direction of movement of the pointer 122. 此外,由于指示器122仅响应于机械撞杆140的压入而移动,所以温度致动元件170的重复升温以及冷却不会导致计数器的多次增加和/或减小。 Further, since the indicator 122 only in response to a mechanical striker lever 140 is moved into the press, the temperature of the actuating member 170 is repeated heating and cooling does not lead to a multiple increase in the counter and / or reduced. 由此,致动器150不会导致标记的改变,直至温度致动元件170已经经历了一次消毒循环而沿一个方向移动致动器150、并且机械撞杆140已经经历了一个使用循环而沿相反的方向移动致动器150。 Thereby, the actuator 150 does not result in a change flag, until the temperature of the actuating element 170 has been subjected to a sterilization cycle and move the actuator 150 in one direction, and the mechanical ram 140 has been subjected to a cycle used along opposite direction of movement of the actuator 150.

随着进行了多次消毒/使用循环,指示器122将沿104的方向逐步移动。 As for a number of sterilization / use cycle, the pointer 122 will move progressively in the direction of 104. 当指示器122进一步沿104的方向移动时,显示出不同的标记,为使用者指示电外科器械100所剩余的使用次数的改变。 When the pointer 122 is further moved in the direction 104, showing different markers, indicating to the user of the electrosurgical instrument 100 changes the number of uses remaining. 如本领域内的技术人员所理解的那样,可采用多种类型及构造的计数器/闭锁机构110而不会偏离本发明的范畴和精神。 As those skilled in the art appreciate, it may take a variety of types and configurations of the counter / lockout mechanism 110 without departing from the scope and spirit of the invention. 例如在一个实施方式中,温度致动元件移动致动器以及指示器,而机械撞杆使得致动器相对于指示器移动。 In one example embodiment, the temperature of the actuating movement of the actuator member and an indicator, while the mechanical actuator such that the lance relative to the movement of the pointer. 在另一个实施方式中,温度致动元件以及撞杆两者或者之一不与致动器直接地相连,而是间接地移动致动器。 In another embodiment, the temperature of the actuating member and the ram, or both are not directly connected with one of the actuator, but indirectly move the actuator. 在另一个实施方式中,温度致动元件以及撞杆不使用致动器就使得标记改变。 In another embodiment, the temperature element and the actuating ram without using an actuator such that the tag will change. 在另一个实施方式中,致动器拉动指示器而使得指示器移动。 In another embodiment, the actuator pulls the pointer such that the pointer moves.

图9示出了电外科计数器/闭锁机构110,其中指示器122移动到最靠近电源线104处,而机械撞杆140处于闭锁位置。 9 illustrates electrosurgical counter / lockout mechanism 110, which is closest to the pointer 122 is moved to the power supply line 104, while the mechanical striker lever 140 is in the latched position. 一旦指示器122移动到最靠近电源线104处,闭锁部分128位于致动器150附近。 Once the indicator 122 is moved to the closest to the power supply line 104, the latching portion 128 of the actuator 150 is located. 片簧180在致动器150上施加一个沿指示器122方向的横向力。 Applying a lateral force of the leaf spring 180 in a direction indicator 122 on the actuator 150. 指示器122位于最靠近电源线104的位置,使得闭锁部分128可以容置致动器150。 Indicator 122 is located closest to the position of the power supply line 104, such that the latching portion 128 can accommodate the actuator 150. 这导致致动器150横向移位到指示器122的闭锁部分128内。 This causes actuator 150 to laterally displace the latching portion 128 of the indicator 122.

机械撞杆140的远端144位于致动器150的槽道154内(视图6B)。 The distal end of the lance mechanical 144,140 positioned within the actuator channel 154, 150 (view 6B). 致动器150横向移位到闭锁部分128内导致机械撞杆140的远端144沿指示器122的方向横向移位。 128 cause actuator 150 to laterally displace the distal end of the latching portion 140 of the mechanical ram 144 in the direction of lateral displacement of the indicator 122. 远端144的横向移位导致接合脊145脱离接合构件190(视图6B)。 Lateral displacement of the distal end 144 of the lead engaging member 190 disengage the ridge 145 (the view 6B). 由此,接合构件190不能再抵消由偏置弹簧148沿端头108a-c方向施加在凸缘146上、从而施加在机械撞杆140上的力。 Thereby, the engagement member 190 can not be applied by the offset 148 in the direction of the tip 108a-c biasing spring on the flange 146, 140 to apply a force on the mechanical striker. 在所示的实施方式中,偏置弹簧148在凸缘146施加一个沿端头108a-c方向的力,使得机械撞杆140的近端142从壳体伸出的长度与端头108a-c的长度大致相等。 In the illustrated embodiment, the biasing spring 148 applies a force in a direction of the tip 108a-c of the flange 146, the proximal end of the lance such that the mechanical 142,140 protrudes from the housing and the length of the tip 108a-c length substantially equal. 在另一个实施方式中,机械撞杆从壳体伸出的长度与端头的长度并不相等或相近。 In another embodiment, the mechanical length of the lance tip projecting from the housing is not the same length or similar.

当电外科器械100完成了其最后的消毒/使用循环之后,指示器122与止挡125接触。 After electrosurgical instrument 100 has completed its final sterilization / use cycle, the indicator 122 in contact with the stop 125. 止挡125由壳体102的下部形成。 The stopper 125 is formed by the lower housing 102. 指示器122沿电源线104方向的进一步的移动被止挡125阻止。 Further movement of the pointer 122 in the direction of the power line 104 is the stopper 125 to stop. 当致动器150被推入到与闭锁部分128接合时,致动器150沿电源线104方向的移动被闭锁部分128阻止。 When the actuator 150 is pushed into engagement with the latch portion 128, actuator 104 moves the actuator 150 along the direction of the power source line 128 is blocked portion blocking. 机械撞杆沿电源线104方向的移动由机械撞杆140的远端144与致动器150的前表面之间的接触所阻止。 Mechanical striker lever 104 moves in the direction of the power line by the mechanical contact between the front surface 150 of the ram 144 and the distal end of the actuator 140 to stop.

当致动器150被推入到与闭锁部分128接合时,致动器150横向地移位。 When the actuator 150 is pushed into engagement with the locking portion 128, the actuator 150 is laterally displaced. 致动器150的横向移位使得槽道154与机械撞杆140的远端144不对齐。 Lateral displacement of the actuator 150 such that the channel 154 and the distal end of the lance 144140 mechanical misalignment. 由此,机械撞杆140的远端144与致动器150的前表面接触而不是滑入槽道154中。 Thus, the front surface of the distal end of the lance mechanical 144,140 of the actuator 150 is not in contact with slide channel 154. 此外,片簧180与致动器150接合,防止致动器横向移动并确保机械撞杆140的远端144不滑回到致动器150的槽道154中。 Further, the leaf spring 180 engages the actuator 150, the actuator prevents lateral movement of the distal end of the lance and secure mechanical 144,140 does not slide back into the channel 154 of the actuator 150.

致动器150的前表面与机械撞杆140的远端144之间的接触阻止机械撞杆140朝电源线104方向的移动。 The contact between the distal end 144,140 of the front surface of the mechanical actuator 150 prevents the striker 140 moves in the mechanical direction of the power cord 104 of the lance. 换句话说,指示器122、致动器150、以及机械撞杆140的并接设置防止机械撞杆140被推入到壳体102内。 In other words, the indicator 122, actuator 150, and a mechanical striker lever 140 is provided to prevent mechanical bonding and the lance 140 is pushed into the housing 102. 由此,一旦完成了预定的消毒/使用循环次数,当使用者意图将端头108a-c插入到电外科的电源(未示)内时,机械撞杆140阻止电外科器械100被使用。 Thus, upon completion of a predetermined sterilization / use cycles, when the user intended to insert the tip 108a-c to an electrosurgical power supply (not shown), the ram 140 prevents the mechanical electrosurgical instrument 100 is used.

如本领域内的技术人员所理解的那样,可采用多种类型及构造的闭锁机构而不会偏离本发明的范畴和精神。 As those skilled in the art appreciate, the locking mechanism can be a variety of types and configurations without departing from the scope and spirit of the invention. 例如,在一个实施方式中,闭锁机构断开一个内部的电连接,阻止电流在电外科器械内的流动。 For example, in one embodiment, the latching mechanism is electrically connected to the interior of a disconnected, prevents current flow within the electrosurgical instrument. 在另一个实施方式中,闭锁机构阻止模块化电外科器械部分的耦合,从而有效地防止电外科器械被使用。 In another embodiment, the locking mechanism prevents the coupling portion of a modular electrosurgical instrument, thereby effectively preventing the electrosurgical instrument being used.
