Description

一种具有击发锁死装置的外科缝合器械 Firing surgical stapling instrument having a locking device

技术领域 FIELD

[0001] 本发明涉及医疗器械领域,特别涉及一种具有击发锁死装置的外科缝合器械。 [0001] The present invention relates to the field of medical devices, and more particularly to firing surgical stapling instrument having a locking device.

背景技术 Background technique

[0002] 在医学科学的外科手术中,自从20世纪60年代的第一把缝钉类产品以来,医用缝合器已成为辅助于刀口缝合过程中的必不可少的一种医疗器械。 [0002] In medical science, surgery, since the first staple products in the 1960s, the medical stapler has become secondary to the edge stitching process is essential for a medical device. 各种外科用医用缝合器正在外科手术中被广泛地用于缝合人体消化道组织、呼吸道组织和血管组织,可以减少手术时间,提高手术质量。 Various surgical stapler with medical surgery is being widely used for stapling the human digestive tract tissue, respiratory tissue, and vascular tissue, can reduce the operation time and improve the quality of surgery. 它们通常被用于消化道中食管、胃、十二指肠、小肠、结肠和直肠等端端、端侧及侧侧缝合手术或痔切除和胃幽门造口等形成通道或闭合切口的手术,也被用于呼吸道中肺和气管等缝合手术和血管组织的缝合手术,特别适用于显露和操作困难的器官和组织的缝合手术。 They are usually used in the digestive tract esophagus, stomach, duodenum, small intestine, colon and rectum end to end, side to side and end stapling or surgical removal of hemorrhoids and the like pyloric passage or stoma surgery incision is closed, and It is used for surgical sutures and surgical suturing blood vessels in the respiratory tract tissues such as the lungs and trachea, especially for suturing surgical exposure and difficult operation organs and tissues.

[0003] 应用缝合器缝合组织时,首先,缝合器处于初始状态时,抵钉座和钉仓组件分离,将待缝合的组织置于钉仓组件和抵钉座之间;然后,握动击发手柄,使得钉仓组件向抵钉座方向靠拢,并通过推进装置的作用推出钉仓组件内的缝钉,从而完成缝合操作;最后,放开击发手柄并按压复位按钮,推进装置与钉仓一起退回到初始状态。 When [0003] the stapling tissue with suture, firstly, the stapler is in an initial state, the anvil and staple cartridge assembly separated, placed in tissue to be stapled between the staple cartridge assembly and the anvil abutment; then, firing the movable grip handle, such that the cartridge assembly closer to the anvil direction, and introduction of the staples by the action of the staple cartridge assembly propulsion device, thereby completing the stapling operation; Finally, release the firing handle and presses the reset button, the propulsion device together with the cartridge return to the initial state.

[0004] 通常在缝合器上安装击发锁死装置,使击发完成后扳机锁死,指示击发已经完成,起到保险作用。 [0004] The locking means is typically mounted on firing the stapler, so that after completion of the firing trigger lock, indicating firing has been completed, the insurance effect. 现有技术中的击发锁死装置通常采用的是具有双轨道的击发锁片,闭合时手柄滑入击发锁片中的第一轨道,完成闭合后松开手柄,手柄滑出该第一轨道,击发时手柄滑入击发锁片中的第二轨道,通常击发锁片的第二轨道会有个卡槽用于卡住滑入的手柄,表示击发已经完成,起到保险作用。 Firing the prior art locking device is usually used with a double locking tab firing track, the first track is closed when the handle slide lock firing sheet, after the completion of the closing release the handle, the handle slipping out of the first rail, the firing handle is slid into the second rail locking discs firing, firing the second rail locking tab generally have a jammed slide slot for a handle, showing the firing has been completed, insurance effect. 但存在的缺陷是通常手柄都能顺利的滑入第一轨道完成器械的闭合,但有的击发锁片为了在击发状态中将手柄导入第二轨道中,在击发锁片的第一轨道的出口设置一条凸起以免手柄在击发过程中滑入第一轨道而无法滑入第二轨道而起到锁死的功能,这样的缺陷就是增大了手柄在完成闭合状态后滑不出击发锁片的第一轨道的风险。 However, the defects are usually able to handle smoothly slide first instrument complete closed track, but some of the firing piece for locking the handle in the firing state into the second track, the first track in the outlet plate of the firing lockout a projection provided to prevent the first slide rail handle during firing and can not slide lock the second track and play functions, such defects is increased after the completion of the handle slide in the closed state of the lock plate does not attack the hair the risk of the first track. 现有技术中也有将上述凸起去掉,改进击发锁片的旋转角度以配合手柄的滑入滑出,但配合的零件相对较多,存在一定的复杂性的缺陷。 The prior art described above has the projections is removed, improving the firing angle of rotation with the lock plate to slide in and out of the handle, but with the relatively large parts, there is a certain complexity of the defects. 现有技术中通常利用弹簧拉动击发锁片绕一固定轴进行旋转运动,对扳机进行锁定,在复位时,由复位按钮的带动或中间有其它连接件带动使击发锁片旋转,使扳机脱离的动作过程。 The prior art typically utilize a spring pulls on the firing latch plate about a fixed axis rotational movement of the trigger lock, at reset, driven by a reset button or other intermediate connection member to drive the rotation of the firing locking disc, the trigger out of course of action.
