Abstract

Disclosed is a split type surgical suture device comprising a main body control part (1), a split part (2), a suture end part (3) and a suture fixing part (4), wherein the split part (2) has one end movably connected with the main body control part (1), and another end connected with the suture end part (3). The suture fixing part (4) is arranged outside the split part (2) and is connected with the split part (2). By arranging a removable split part (2) between the main body control part (1) and the suture end part (3), medical staff only need to replace the split part (2) to proceed a second operation when an operation is completed. That is, the main body control part (1) can be repeatedly used after disinfection, while the split part (2) is disposable, which effectively prolongs the service life of the suture device and reduces its manufacturing cost. This structure is used for the suture of deep ligament tissues, the operation is simple and convenient, has high success rate in one-time suture, and can provide repeated suture, which greatly shortens the operation time and makes the suture accurate.

Description

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 surgeon during the suture fixation during the operation are disposable, which cannot be reused, which makes the cost of making the stapler high; and when the deep ligament tissue of the cavity needs to be sutured and fixed, When using a traditional needle holder to hold the suture needle for suture fixation, due to the deep operation site and the narrow space, a large amount of surrounding tissues must be separated to form a large space at the operation site, which can be sutured under the direct view of the surgeon; The tissue damage is large and the adjacent organs are easily damaged. Even so, due to the small and deep operating space and insufficient space lighting, it is still difficult to suture. The power of one-time suture is not high, which prolongs the operation time.
技术问题technical problem
有鉴于此，本发明的主要目的在于提供一种分体式手术缝合器，解决了腔隙深部韧带组织缝合困难，易损伤邻近器官，且现有技术中缝合器不能重复利用，导致其制作成本高的问题。In view of this, the main purpose of the present invention is to provide a split surgical stapler, which solves the difficulty in suturing the deep ligament tissues of the lacuna and easily damages adjacent organs. In addition, the stapler in the prior art cannot be reused, resulting in high manufacturing costs. The problem.
