具体实施方式 Detailed ways

[0049] 为了能够更清楚地描述本发明的技术内容,下面结合具体实施例来进行进一步的描述。 [0049] In order to more clearly describe the technical contents of the present invention, the following embodiments in conjunction with the specific embodiments to be further described.

[°°50] 传统内窥镜一般达到最大调弯角度时的拉力较大,最大可达5公斤力,如果在远端弯曲状态下再输送较大的器械,器械自身又会施加弯曲通道一定的背向张力,使牵引丝受到的拉力更大,从而对牵引系统的拉伸强度提出更高的要求。 [°° 50] Traditional endoscopy typically reaches a maximum when a large tension bending angle adjustment, the maximum up to 5 kgf, and then conveying the large instrument if the state in which the distal end is bent, the instrument will apply bending channel itself must facing away from the tension, so that by pulling the pull wire is larger, so that higher demands on the tensile strength of the traction system. 通常情况下,工作孔道要求内径越大越好,外径越小越好,外径小可以减少对人体血管的损伤,内径大可以输送更大的器械,因此传统内窥镜要求管体的管壁必须尽量的薄,即要求牵引系统在管壁内的部分的体积必须尽量小。 Typically, the inner diameter of the working channel requires bigger the better, the better the smaller the outer diameter, the outer diameter can reduce the damage to the small blood vessels of larger inner diameter larger instruments may be delivered, so in conventional endoscopic claim wall of the tubular body We must be as thin as possible, i.e. the volume required traction system portion in the tube wall must be as small as possible.

[0051] 而本发明则通过改变牵引丝通道的排列给予了一种新的解决方案,即在内道管6的外壁或插入部3的内壁上沿轴向方向设置有至少部分相互贴合的牵引丝通道U。 [0051] The present invention, by changing the arrangement of the traction wire channel given a new solution, i.e. the external wall 6 of the inner track or on an inner wall of the insertion portion 3 is provided at least partially bonded to each other in the axial direction U. pull wire channel 为了更好的说明本发明的优点,请参阅图2,该牵引丝聚拢组件I包括四个牵引丝通道11和固定环12,沿牵引丝通道11沿轴向方向设置于固定环12的内壁,相邻的牵引丝通道11的外缘至少部分相互贴合,所述的牵引丝通道11的横截面呈圆形,且两个相邻的所述牵引丝通道11的外缘相外切。 In order to better illustrate the advantages of the present invention, please refer to FIG. 2, the pull wire bunching assembly I comprises a four-channel pull wire 11 and the stationary ring 12, the channel 11 along the pull wire disposed in the axial direction to the inner wall 12 of the stationary ring, adjacent the outer edge of the pull wire channel 11 is at least partially bonded to each other, the dragline passage 11 circular in cross section, and two adjacent outer edges of the pull wire 11 relative to the outer channel cut.

[0052] 而图1则表示一种传统牵引丝通道11的分布方式,本发明的图2与图1相比较,在牵引丝通道11与内道管6的直径不变的情况下,牵引丝聚拢组件I的排列方式可以留出更大的空间,便于结合手术需要做出相应变动,例如可以减小内窥镜插入部3的外部尺寸,留出空间插入第二根工作孔道,实现双工作孔道手术,或者,根据手术要求需要改变牵引丝5的直径时,可以在相应的弯曲部2和插入部3的直径不变的情况下增加牵引丝通道11的直径,放置相对直径大的牵引丝5,保障牵引丝通道11内通过的牵引丝有足够的牵引力度,实现大角度的弯曲控制的同时达到弯曲轻松自如,从而达到符合临床的应用要求。 [0052] FIG. 1 shows the distribution and manner of a conventional pull wire channel 11, FIG. 2 of the present invention as compared to FIG. 1, in a case where the pull wire channel 11 and the inner diameter of the channel 6 of constant, dragline I bunching arrangement of components may be left out of more space, easy to corresponding changes need to be made in conjunction with surgery, for example, to reduce the outer dimension of the endoscope insertion portion 3, leaving a space to insert a second root working channel, dual work channel operation, or change request requires surgical traction wire diameter 5 can be increased diameter of the traction wire channel 11 in the case where the diameter of the respective curved portion 2 and the insertion portion 3 of the constant, relatively large diameter disposed dragline 5, to protect the pull wire through the pull wire channel 11 has sufficient traction efforts to achieve simultaneous control of the bending angle reaches a large bending ease, so as to achieve compliance with the requirements of clinical applications.

[0053] 此外,该牵引丝聚拢组件I的牵引丝通道11并列排列的设计使得牵引丝通道11受操作手柄4控制后沿同一方向产生纵向力,从而达到输送装置需要的回弹与韧性的作用功會K。 [0053] In addition, the pull wire bunching I dragline assembly passage 11 arranged in parallel channels designed such that the pull wire 11 by operating the control lever 4 to produce the longitudinal force in the same direction, so as to achieve the resilience and toughness required delivery device Gong will K.

[0054] 请参阅图3,该微创手术器械输送装置包括弯曲部2、插入部3、操作手柄4、牵引丝 [0054] Referring to FIG. 3, the delivery device minimally invasive surgical instrument comprises a curved portion 2, the insertion portion 3, an operation handle 4, dragline

5、内道管6和一个牵引丝聚拢组件1,除牵引丝聚拢组件I外,其余部件均按照现有技术安装完成,牵引丝5需要穿过牵引丝通道11达到聚拢的效果,若该牵引丝聚拢组件I不包括固定环12,则仅在装置内部做出改动,牵引丝通道11可以直接设置于内道管6的外壁或插入部3的内壁上(图3中未标出),若该牵引丝聚拢组件I包括固定环12,则该牵引丝聚拢组件I需要安装于弯曲部2和插入部3之间(图3中未标出)。 5, the inner tube 6 and a channel pull wire bunching assembly 1, in addition to the pull wire bunching I component, the remaining components were carried out with the prior art installation, the pull wire through the pull wire 5 needs to gather channel 11 to achieve the effect, if the tow I bunching wire assembly includes a stationary ring 12 is not, then only make changes in the apparatus, the traction wire channel 11 may be directly provided in the channel between the outer wall or tube of the insertion portion 3 of 6 (not shown in FIG. 3), if the pull wire bunching assembly I includes a stationary ring 12 between the pull wire bunching assembly 3 is attached to the I need the insertion portion 2 and the bending portion (not shown in FIG. 3).

[0055] 在一种优选的实施方式中,内道管6分别与各个牵引丝通道11的外壁至少部分相互贴合。 [0055] In one preferred embodiment, the inner tube channel 6 are at least partially bonded to each other with the outer wall 11 of each channel pull wire. 经计算,除内道管6和插入部3的固定体积外的预留的空间可以使牵引丝5必定成聚拢状态直至操作手柄4。 Calculated, space reserved channel volume in addition to the fixed tube 6 and the insertion portion 3 of the traction wires 5 may be gathered into a bound state until the operating handle 4.

[0056] 此外,还可以在操作手柄4与聚拢组件I之间加入一个牵引丝分路过渡部件,由于牵引丝5在插入部3内部一直保持聚拢的状态,直至操作手柄4端才分散,而分散角度过大会导致牵引丝变形过渡,操作手柄4在控制牵引丝5的时候具有较大的阻力,因此在操作手柄4和牵引丝聚拢组件I之间加入一个缓冲部件(即牵引丝分路过渡部件)使牵引丝在分散状态和聚拢状态之间有一个相对分散的中间状态,增加操作安全性和可靠性。 [0056] In addition, a traction operation may also be added to the handle 4 between components I and bunching wire member branch transition, since the pull wire 5 in the insertion portion 3 remains inside the gathered state until the end of the operation lever 4 until the dispersion, and too dispersion angle of deformation results in a transition dragline operating handle 4 has a large resistance when pulling the control wire 5, thus join a gather buffer member between the operating handle 4 components I and traction wires (i.e., the pull wire transition branching member) so that the pull wire has a relatively dispersed state in an intermediate state between the dispersion and gathered state, increase operational safety and reliability.

[0057] 其中,牵引丝5为钢丝,牵引丝通道11为螺旋弹簧管,起到减振缓速的效果。 [0057] wherein the pull wire is a steel wire 5, pull wire passage tube 11 is a coil spring, the damping effect of the retarder of play.

[0058]同时,插入部3具有刚柔性以及便捷性,能够实现定位插入,且该微创手术器械输送装置前端的弯曲部2通过正确选择插入位置,有助于插入部3准确快速的插入至指定目标处。 [0058] Meanwhile, the insertion portion 3 has a rigid flexible and convenience, positioning insert can be achieved, and the front end of the delivery device minimally invasive surgical instrument by selecting the bent portion 2 in the correct position, quickly and accurately facilitate the insertion portion 3 is inserted into the designated target.

[0059] 在一种优选的实施方式中,微创手术器械输送装置还包括测漏阀7,测漏阀7与操作手柄4的第二端连接。 [0059] In one preferred embodiment, the minimally invasive surgical instrument further comprising a leak valve delivery device 7, the operating handle 7 and the leak valve 4 is connected to the second end.

[0060] 其中,密闭的测漏阀7可以隔离水分并允许气体通过,测漏阀7外部接有可开启的阀体连接器后,可以进行装置的事前密封性能检查,检测该装置是否可以进行液体消毒清洗 [0060] wherein the leak valve 7 may be closed and allow gas through the moisture separator, leak valve 7 is connected with the external connector can be opened after the valve body, the sealing performance can be pre-inspection apparatus, detecting whether the device can be liquid disinfecting cleaning
