背景技术Background technique

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。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。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。 In the surgical operation of medical science, since the first staple product in the 1960s, the medical stapler has become an indispensable medical device in the process of suturing the knife edge. Various surgical medical staplers are widely used in surgical operations to suture human digestive tract tissues, respiratory tract tissues and vascular tissues, which can reduce operation time and improve operation quality. They are usually used for end-to-end, end-to-side, and side-to-side suture operations such as esophagus, stomach, duodenum, small intestine, colon, and rectum in the digestive tract, or operations for forming channels or closing incisions such as hemorrhoidectomy and gastric pylorostomy. It is used in the suture operation of the lung and trachea in the respiratory tract and the suture operation of blood vessel tissue, especially suitable for the suture operation of organs and tissues that are difficult to expose and operate. the

外科切割缝合器械中，直线切割缝合器具有缝合与切割两个功能，在进行伤口缝合的同时，将多余的组织切除，直线切割缝合器已被广泛用于外科手术的伤口缝合、内部组织缝合与切割中。现有的直线切割缝合器一般包括上、下两个钳夹，以及用于闭合上、下钳夹的闭合把手，相对设置在上、下钳夹前端的钉仓和抵钉座，设于钉仓内并可同时相对于钉仓移动的击发片和切刀，以及用于驱动击发片和切刀移动的推扭。钉仓内排列设有缝合钉，击发片依次推动推钉片并将缝合钉推向抵钉座，所述的切刀将位于钉仓和抵钉座之间的组织切断，在这些过程中，通过行程指示装置能 更好的了解器械的工作状态，在现有技术中，以直线切割缝合器为例，申请公布号为CN102813539A的专利申请公布了一种带有行程指示装置的直线切割缝合器，该申请公布的技术方案虽然解决了常见的直线切割缝合器不能明确显示切刀和击发片的行程而对手术操作带来不便的缺陷，但该技术方案仍存在不足，由于行程指示装置的部分滑槽设置在手柄外壳内，当用力按压手柄外壳时，可能会导致滑槽有一定程度的变形而导致其他零件难以配合，此外，限制传动齿轮单向旋转的零件比较复杂而导致对零件的配合度的要求较高。基于现有技术中的上述不足，有待提出新的行程指示的技术方案。 Among the surgical cutting and suturing instruments, the linear cutting and suturing device has two functions of suturing and cutting.
