Description

Technical Field

[0001] The utility model relates to the technical field of suturing devices, in particular to a minimally invasive fascia suturing device with the functions of positioning, grasping and preventing slipping. Background Art

[0002] In current clinical laparoscopic surgery, if the peritoneum and fascia layers are not sutured, it is easy to form intra-abdominal omentum or intestinal hernia or local adhesion, leading to the possibility of incomplete intestinal obstruction, often causing problems such as puncture hole bleeding and puncture hole hernia. Complications increase the patient's pain; therefore, it is necessary to use a suturer to suture it.

[0003] Due to the different weights and thicknesses of the patients' abdominal walls, in order to achieve the best subcutaneous suture effect, the insertion depth of the stapler has a safe and appropriate range, and the stapler needs to be properly positioned and fixed during operation. The existing staplers do not have the function of positioning and grasping the thread during use, and the suture thread is easy to slip off, which will affect the suturing effect and bring safety hazards. For this reason, we propose a minimally invasive fascia suturer with positioning, grasping and anti-slipping functions. Utility Model Content
