Description

一种手术用能量器械及超声手术刀 技术领域
本发明涉及医疗设备领域，尤其涉及一种手术用能量器械及超声手术刀。
背景技术
手术用能量器械，比如采用超声能量的超声手术刀被广泛用于各种腔镜手术和常规手术中，在手术前，医院设备科的医护人员需要为手术准备手术用的器材和耗材等，若涉及到能量器械，一般需要到对其使用寿命进行确认。
为了记录能量器械的剩余可用次数，现有技术中研发出了具有使用次数统计功能的能量器械，比如公告号为CN211187449U的中国实用新型专利，其公开了一种超声手术刀，其设置了信息记录装置来记录换能器的使用次数、剩余使用次数，还设置有显示设备来显示从信息记录装置处接收的各种信息，供手术操作者参考。并且其还公开了当信息记录装置记录的使用次数大于等于预设的使用次数阈值时，发出警告信息。
但是，现有技术中，要查看设备状态，比如使用次数，则需要接通外部电源来启动超声手术刀，接线操作比较麻烦；现有技术中还有一种手术用能量器械，比如公告号为CN207804334U的中国专利，公开了一种无线缆超声手术系统，即在驱动手柄内设置储能装置为超声波驱动器供电，使得超声手术刀不用外接电源也能使用，但是其原理也是，虽然免去了接电源线的繁琐操作，但是，在非手术的阶段接通内置电池来启动超声手术刀以查看设备状态，造成了电能的损耗。而且，无线缆超声手术系统价格比较昂贵，电池的续航时间和输出电能的稳定性均无法与外接交流电使用的有线超声手术系统相比，因此，目前有线超声手术系统还是主流器械产品。

附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请中记载的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本公开的一个示例性实施例提供的具有双模式供电电路的手术用能量器械的结构示意图；
其中，附图标记包括：1-操作键，2-内置电池，3-控制单元，41-第一功耗电路，42-第二功耗电路，51-第一功耗电路，52-第二功耗电路，6-电源接头。
具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、装置、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其他步骤或单元。
在手术前，医院设备科的医护人员需要为手术准备手术用的器材和耗材等，若涉及到能量器械，一般都涉及到对其使用寿命进行确认，以防止在手术开始后发现能量器械的剩余可用次数为零。对此，传统的解决办法为在每次术后整理器材时，采用人工的方式记录各个能量器械的剩余可用次数，更先进的办法可能是能量器械本身具有剩余次数的统计功能，可以供设备科实时查询。但是医院内各流程责任分明，操作手术的医生是没有在实施完手术停用前查询剩余可用次数并记录的义务，这就需要设备科在术前检查时对能量器械上电后进行剩余可用次数的查询操作。无论是对剩余可用次数人工记录还是上电查询，都 不是很方便，本发明的构思在于提供一种手术用能量器械在未接入外部电源的情况下对器械剩余可用次数进行便捷查询的解决方案。
在本发明的一个实施例中，提供了一种具有双模式供电电路的手术用能量器械，被配置为通过电源接头6与外部电源连接，参见图1，所述手术用能量器械包括操作键1、内置电池2、控制单元3、第一功耗电路41、第二功耗电路42，其中，所述第二功耗电路42为驱动电路或数字处理电路，其中，驱动电路可以被配置为驱动能量发生器，即换能器的能量发生器功放模块，也可以被配置为驱动开关管或电机；所述数字处理电路可以为CPU或DSP等数字电路。所述第一功耗电路41的功耗小于第二功耗电路42的功耗，其被配置为在控制单元3的控制下提示所述手术用能量器械的状态参数，所述状态参数以器械的剩余可用次数为例，对第一功耗电路41的几种表现形式作出如下说明：
第一种形式为第一功耗电路为显示单元，比如液晶显示屏，其被配置为在控制单元的控制下显示所述手术用能量器械的状态参数；
第二种形式为第一功耗电路为扬声器单元，其被配置为在控制单元的控制下播放语音消息，比如“当前剩余可用次数为7次”；
第三种形式为第一功耗电路为指示灯装置，可以包括多种颜色，比如绿灯亮表示当前剩余可用次数大于或等于20次，黄灯亮表示当前剩余可用次数大于或等于3次且小于20次，红灯亮表示当前剩余可用次数小于3次；本发明不限定于颜色来反映所述手术用能量器械的状态参数，比如还可以以指示灯的不同亮度来反映当前剩余可用次数，越亮表示次数越多，越微弱表示次数越少；还可以比如在不同的指示灯处标记“＞20”、“[5-20]”、“＜5”，根据实际剩余可用次数来点亮相应区域的指示灯，等等。
剩余可用次数可以如背景技术中所提及的现有技术CN211187449U，设置信息记录装置来记录换能器的实际使用次数，通过计算得到剩余可用次数；当不接外部电源的情况下，触发控制单元和第一功耗电路时，控制单元向信息记录装置查询剩余可用次数，并将查询结果发送至第一功耗电路，实现提示功能。
为了实现在不接入外部电源的情况下驱动所述第一功耗电路41，所述手术用能量器械还包括开关电路，本实施例中，所述开关电路可为如下设计：
参见图1，所述开关电路包括初始状态均为关断状态的第一功率开关管51(即图1中的开关管Q1)、第二功率开关管(即图1中的Q2)、第三功率开关管(以下简称开关管开关管Q3)和第四功率开关管(以下简称开关管开关管Q4)，其中开关管Q1的控制端 通过所述操作键与所述内置电池连接，且被配置为若开关管Q1导通，则所述控制单元、第一功耗电路均接入所述内置电池的负极；
所述开关管Q2的控制端与开关管Q1的一端连接，且被配置为若开关管Q2导通，则所述控制单元3、第一功耗电路41均接入所述内置电池2的正极；
所述开关管Q3的控制端通过电源接头6与外部电源连接，且被配置为若开关管Q3导通，则所述第二功耗电路42接入所述外部电源的负极；
所述开关管Q4的控制端与开关管Q3的一端连接，且被配置为若开关管Q3导通，则所述第二功耗电路42、控制单元3均接入所述外部电源的正极；
由图1可以看出，所述第二功耗电路42不接入所述内置电池2的正极或负极。
以图1为例，开关管Q1和开关管Q3为Nmos管，其开关特性为当栅极电压高于一定的电压值，则开关管导通，否则处于截止状态；所述开关管Q2和开关管Q4为Pmos管，其开关特性为当栅极电压低于一定的电压值，则开关管导通，否则处于截止状态；
所述开关管Q2的控制端通过图1中的电阻R2与内置电池2的正极连接，开关管Q4的控制端通过图1中的电阻R1与内置电池2的正极连接，以使其栅极电压均高于导通电压阈值，此时开关管Q2与Q4初始的状态为截止状态(关断状态)；
初始状态下，开关管Q1的栅极通过电阻R7接地而处于低电平，其栅极电压被拉高有两种途径，分别作出如下说明：
第一种途径为在手术用能量器械与外部电源断开连接的情况下，按压操作键1可以使内置电源2的正极向开关管Q1的栅极提供高电压使其导通，操作键1可选用受外力按压则使电路导通的按键，若所述操作键被按压，则所述开关管Q1保持导通状态；若所述操作键被松开，则所述开关管Q1由导通状态转换为关断状态。这样，设备科医护人员在查询剩余可用次数时可以长按操作键1以有足够的时间来记下相应的查询结果；或者，在操作键被按压后延时一段时间，比如10秒后，控制单元向所述开关管Q1的控制端发送一个低电平，以使所述开关管Q1由导通状态转换为关断状态，这种情况下需要另外设置一个与所述控制单元电连接的定时器，但是不需要人手一直按压操作键1。
第二种途径为手术用能量器械与外部电源连接的情况下，首先开关管Q3的栅极电压受接入外部电源的影响而被拉高，开关管Q3导通后，开关管Q4的栅极通过导通的开关管Q3接地，即开关管Q4的栅极电压被拉低，则开关管Q4相继导通；进一步地，外接电源通过导通的开关管Q4和电阻(参见图1中的R8和R6)拉高开关管Q1的栅极电压，则 开关管Q1导通。
若所述开关管Q1导通，则所述开关管Q2的栅极电压被拉低而导通。
以上对开关电路的各个功率开关管之间的触发导通关系进行了详细的说明。
以上开关管Q4-Q1可以实现当内置电池供电时，仅使小功耗电路可以由操作键1触发工作，而能量发生器功放电路不取电(不工作)，既可以短时间查看设备状态参数，又因为不接入大功耗电路而不会给电池带来过多的损耗，延长电池的使用寿命而不需要在器械的生命周期内频繁更换电池(不可充电电池的情况)，并且小容量的电池即可满足需求；当外部电源供电时，全部电路(包括大功耗电路和小功耗电路)均取电(进入工作状态)。
即在手术用能量器械与外部电源断开连接的情况下，按压操作键1，则所述内置电池触发所述开关管Q1导通，进而所述开关管Q1的导通触发开关管Q2导通，以使所述控制单元、第一功耗电路41处于工作状态，此时控制单元可以将预先设定的设备状态参数发送至第一功耗电路41，进而第一功耗电路41作出提示动作，参见上文所述的显示屏或扬声器或提示灯的相关方案的记载，在此不再赘述。
当所述手术用能量器械与外部电源连接时，则开关管Q3栅极电压被外部电源拉高而使开关管Q3导通，进而所述开关管Q3的导通触发开关管Q4导通，以使所述控制单元3、第二功耗电路42、第一功耗电路41的VCC端均接入外接电源的正极。如上所述，开关管Q4的导通会触发开关管Q1导通，则第一功耗电路41和控制单元3的VSS端接入外接电源的负极(接地)，此时控制单元3、第二功耗电路42、第一功耗电路41均进入工作状态。
参见图1，所述控制单元3还与所述开关管Q3的栅极连接，响应于接入内置电池或外部电源，所述控制单元检测所述开关管Q3的栅极电压，并通过所述开关管Q3的栅极电压来判断所述电源接头6是否与外部电源接通，具体为，如果开关管Q3的栅极管脚电平为高电平，则说明器械当前由外部电源供电，若为低电平，则说明器械当前由内置电池供电。本发明对内置电池具体的内置位置不作具体限定。
所述控制单元3还与开关管Q1的栅极连接，并通过所述开关管Q1的栅极电压变化来判断所述操作键1是否被按压，具体为通过上文判断出外部电源供电或内置电池供电的前提下，在内置电池供电的情况下，若开关管Q1的栅极管脚电平由低电平转为高电平，则说明当前操作键1被按压；在外部电源供电的情况下，若开关管Q1的栅极电平幅值进一步被提高，则说明当前操作键1被按压。
关于操作键，包括两种不同的实施方式：
第一种方式为所述操作键为专用于控制启动所述第一功耗电路的按键，即在现有的手术用能量器械的操作键基础上再增加新的按键；
第二种方式为不需要在现有的手术用能量器械的操作键基础上再增加新的按键，可以选用现有的其中一种或多种功能键作为触发第一功耗电路41启动的启动按键，这种方式下，所述操作键(选用的功能键)具有第一工作模式和第二工作模式，若所述手术用能量器械与外部电源断开连接，则所述控制单元控制所述功能键工作在第一工作模式，包括：若所述功能键被按压，则触发所述开关管Q1导通；若所述手术用能量器械与外部电源连接，则所述控制单元控制所述功能键工作在第二工作模式，包括：若所述功能键被按压，则开启除触发所述开关管Q1导通以外的功能。具体地，所述除触发所述开关管Q1导通以外的功能包括以下功能中的任一种：
所述功能键为激发按键，若所述激发按键被按压，则激发所述手术用能量器械的能量发生器发生能量；或者，
所述功能键为功率档位按键，若所述功率档位按键被按压，则调节所述手术用能量器械的能量发生器的输出功率；或者，
所述功能键为刀头控制按键，若所述刀头控制按键被按压，则控制所述手术用能量器械的刀具端部作夹合动作。本发明并不限定以上激发按键、功率档位按键、刀头控制按键作为选用的全部范围，现有的能量器械上的本有功能键均可以被选用而具有所述第一工作模式和第二工作模式。
在本发明的一个实施例中，所述内置电池为可充电电池，若所述手术用能量器械与外部电源连接，则所述可充电电池通过所述开关管Q4与所述外部电源连通，具体为，如上文所述，响应于手术用能量器械与外部电源连接，开关管Q3导通，再开关管Q4、Q1、Q2相继导通，此时，外部电源通过导通状态的开关管Q4和Q2为可充电电池充电。
本发明对手术用能量器械不作具体的限定，在本发明的一个实施例中，所述手术用能量器械为超声刀、电刀或者激光刀。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些 要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
