technical field

The invention relates to the technical field of medical devices, in particular to a sacrospinous ligament suture device.

Background technique

At present, sacrospinous ligament fixation is one of the commonly used surgical methods for middle pelvic prolapse, and it is one of the important auxiliary surgical methods for anterior and posterior pelvic prolapse surgery. The recurrence rate is low, and polypropylene mesh does not need to be implanted. However, the current suturing methods are often ordinary needle-holding needle suture, Capio stapler, miyazaki forceps, sacrospinous ligament suture hook, etc. These all need to confirm the sacrospinous ligament first. The confirmation process is to hold the sacrospinous ligament with a tissue forceps, and then use the Capio suture device, miyazaki forceps, sacrospinous ligament suture hooks, etc. to suture without visual guidance. They are all operated under invisible circumstances, and it is not easy to grasp the depth of suture, and it is easy to suture too deep or in the wrong place, which may damage blood vessels or nerves, resulting in medical accidents.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a sacrospinous ligament suture device, which can be sutured after clamping the sacrospinous ligament with forceps, without using other equipment, and can ensure the accuracy of suture.
