技术领域technical field
本发明涉及医疗器械技术领域，特别涉及一种钛夹钳。The invention relates to the technical field of medical instruments, in particular to a titanium clamp.
背景技术Background technique
在大多数腹腔镜手术程序中，外科医生经常会使用钛夹钳将钛夹施加到血管以终止血液的流动。市场现有的钛夹钳包括器身、扳机、手柄、旋转钮、钳杆，器身上设置有下盖组件，下盖组件上设置有施夹推杆、钳口固定板、闭合件和钳口，钳口包括第一夹抓和第二夹抓，通过施夹推杆带动闭合件的运动实现第一夹抓和第二夹抓闭合，而钳口与闭合件组成了一个矩形截面，要保证钳口闭合与张开的往复运动，闭合件与钳口间要有装配间隙，由于钳口远端与施夹推杆存在一定的距离，则钳口相当于一个悬臂梁，在钳口远端完全闭合时，上述装配间隙将会放大钳口远端的纵向错位量。由此，钛夹钳在实际操作过程中存在钳口闭合时错位而导致钛夹不良成形的情况，从而不能有效闭合血管。During most laparoscopic procedures, the surgeon will often use titanium clips to apply titanium clips to blood vessels to stop the flow of blood. The existing titanium clamps in the market include a body, a trigger, a handle, a rotary knob, and a pliers rod. , the jaws include the first gripper and the second gripper, and the closure of the first gripper and the second gripper is realized by driving the closure member through the clamping push rod, and the jaws and the closure member form a rectangular cross-section, which must be ensured For the reciprocating movement of the jaw closing and opening, there must be an assembly gap between the closing part and the jaw. Since there is a certain distance between the far end of the jaw and the clamping push rod, the jaw is equivalent to a cantilever beam. When fully closed, this assembly gap will magnify the amount of longitudinal misalignment at the distal end of the jaws. Therefore, in the actual operation process, the titanium clips may be dislocated when the jaws are closed, resulting in poor shape of the titanium clips, so that blood vessels cannot be effectively closed.
因此，怎样避免钛夹钳的钳口在闭合时产生纵向错位，是本领域技术人员需要解决的问题。Therefore, how to avoid the longitudinal dislocation of the jaws of the titanium clamp when closing is a problem to be solved by those skilled in the art.
