分体式手术缝合器Split surgical stapler

技术领域technical field

本发明属于医疗器械技术领域，涉及一种手术用缝合器，具体涉及一种分 体式手术缝合器。The invention belongs to the technical field of medical instruments, and relates to a surgical stapler, in particular to a split-type surgical stapler.

背景技术Background technique

目前，手术过程中术者在进行缝合固定时所用的缝合器大多为一次性的， 不能实现重复利用的目的，从而使得制作缝合器的成本高；并且对于腔隙深部 韧带组织需要缝合固定时，用传统的持针器夹持缝针缝合固定时，由于操作部 位深而空间狭小，必须大量分离周围组织，在操作部位形成一个较大的空间， 在术者直视下才能缝合；这样对周围组织损伤大，易损伤邻近器官，且即使这 样，因操作空间小而深、空间照明不足的因素，缝合仍有一定难度，一次性缝 合成功率不高，延长了手术时间。At present, most of the staplers used by the operator for suture and fixation during the operation are disposable and cannot be reused, so the cost of making the staplers is high; When the traditional needle holder is used to hold the needle for suture and fixation, due to the deep operation site and the narrow space, a large number of surrounding tissues must be separated to form a larger space at the operation site, and the suture can only be performed under the direct vision of the operator; Tissue damage is large and adjacent organs are easily damaged. Even so, due to the small and deep operating space and insufficient lighting, suture is still difficult, and the success rate of one-time suture is not high, which prolongs the operation time.
