Description

一种显微血管电凝吸引刮匙 技术领域
本发明涉及一种显微血管电凝吸引刮匙。
背景技术
目前，外科手术中涉及到显微操作的精细手术刮匙种类繁多，但大多数仅实现刮匙的单一功能，对于腔内出血或积液，血管夹闭及吸引往往需要其他器械或手术助手配合完成，导致手术效率低下、操作繁琐。
虽然市场上已出现带有吸引功能的显微刮匙，可以取代助手配合，由主刀医生独立操作完成刮匙和吸引的操作，但对于微血管夹闭仍然借助专用的血管电凝器械(双极电凝镊)，电凝功能仍然受限。
对于传统的双极电凝镊，从临床角度使用情况来看，其提供的咬合力不够，切精细程度不能满足使用需求，用力过猛会导致镊头端错位，严重影响手术效果，接触面积小，电凝效果也不尽如人意。由于手术过程中需要主刀医生长时间单手握持，现有的刮匙或显微镊在使用舒适度及人体工程学设计考量较少，在长时间手术过程中容易出现器械滑脱的问题，严重干扰手术进程。
因此，针对以上问题，本发明创造提供一种集成多种功能的显微血管电凝吸引刮匙。

工作原理：
如图16-19所示，在使用过程中，医务人员通过控制器8上的触控显示屏8A设定设定医用吸引泵和医用高脉冲电凝机的工作参数，然后手持握柄5将吸引管2探入患者的病灶手术部位；正常状态下环形刮匙1处于张开状态，且张开角度为60°，医务人员可利用位于吸引管2前端的环形刮匙1进行手术操作；
医用吸引泵启动后会产生负压，通过吸引连接胶管6和握柄5将负压传动至吸引管2的前端；但位于握柄5中部的吸引管控制阀3的一端与中空的握柄5相连通，另一端与外界大气相连通，因此会造成泄压，使得吸引管2的前端的负压降低、吸力减小，无法将环形刮匙 1从病灶部位挂取下来的组织及淤血吸入吸引管2内，医务人员可用手指适当堵住吸引管控制阀3，适当提高吸引管2前端的吸力，进而满足使用需求，当吸引管控制阀3被完全堵住时吸引管2前端的吸力最大；
高脉冲电凝机可对人体组织进行电击凝血，从而抑制刮匙部位出血；位于握柄5内的固定触接块4F上设有触点，该触点通过线缆与线缆插头5C相连接，电缆7的一端连接在线缆插头5C上，另一端连接在电缆接口8B上，电缆接口8B与控制器8内的高脉冲电凝机相连接；
当医务人员需要电凝止血时，按下电凝控制开关4上的开关按键4B，开关按键4B在压缩按键弹簧4J的同时带动直动齿条4K向下运行，直动齿条4K与直动齿轮4M相啮合，直动齿条4K会带动直动齿轮4M转动；
直动齿轮4M通过齿轮轴4I带动滑动齿轮4H转动，滑动齿轮4H与滑移齿条4D相啮合，滑移齿条4D又固定安装在平动滑移板4C上，而平动滑移板4C安装在握柄5内的滑动槽中，所以当滑动齿轮4H转动时会通过滑移齿条4D平动滑移板4C带动触点连接板4E向前运动，一方面使得2个触点连接板4E的触点分别与2个固定触接块4F上的触点相接触，另一方面也带动电凝导杆4G向前运行；
电凝导杆4G向前运行后会推动转推杆4N绕摆动轴4P转动，转推杆4N的下端与刮匙杆4Q的后端相铰接，进而向后拉动刮匙杆4Q；刮匙杆4Q的前端又与拉杆孔1C相铰接，环形刮匙1的刮匙转轴1B间隙配合安装在刮匙孔2A内，刮匙杆4Q的向后运动会使得环形刮匙1绕刮匙转轴1B转动，进而拉动环形刮匙1由张开状态变为收回状态。
高脉冲电凝机与固定触接块4F上的触点相连，并且触点连接板4E、电凝导杆4G、转推杆4N、刮匙杆4Q、环形刮匙1均采用金属导体材料制成，因此可以构成回路将高脉冲电凝机产生的电流传导至环形刮匙1，从而产生与双极电凝镊相同的电击凝血效果，满足止血需求；
反之，当需要停止电击凝血时，操作人员解除对开关按键4B的按压，按键弹簧4J弹性势能释放，进而使得环形刮匙1恢复张开状态，触点连接板4E上的触点也与固定触接块4F上的触点脱离，电击凝血结束。
