Reverse laparoscope incision stitching instrument

Abstract

The invention discloses a reverse laparoscope incision stitching instrument which comprises a forceps type needle holding handle and a stitching instrument front needle end structure. The needle end is of a U-shaped structure, and suturing is conducted from the abdominal wall inner layer peritoneum to the outer side muscle layer and subcutaneous tissue. And the problem of difficulty in suturing patients with obesity and abdominal wall thickness is effectively solved. The laparoscope stitching instrument is convenient to use, comfortable to operate and easier for an operator to master due to the forceps type operating handle. Meanwhile, an abdominal wall fixing device is not needed in the stitching process, positioning is accurate, stitching is quick, stitching is performed under laparoscope monitoring, and surgical safety is improved.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a laparoscopic incision suturing instrument. Background technique [0002] With the development of minimally invasive technology, laparoscopic surgery is widely used clinically. Data show that nearly 70-80% of abdominal operations in my country can be completed under laparoscopy. Laparoscopic manipulation must create a channel through the abdominal wall through a puncture cone. At present, the size of the puncture cone is 5mm-15mm, and the puncture hole in the abdominal wall is larger than 5mm. In order to avoid bleeding and incisional hernia, the peritoneum and fascia must be sutured. Traditional curved needle sutures cannot be completed for such small incisions, especially obese patients with thick abdominal walls. The existing abdominal incision stapler usually works by puncturing the device from outside to inside, that is, puncturing and suturing from the subcutaneous tissue and mu...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects of poor suturing precision, low operation safety and complicated operation in the prior art, the present invention provides a reverse suture method, which improves the suture precision and avoids the common suture position deviation problem in suture

At the same time, the hook-type reverse suture is easy to operate, fast in suture speed, and not easy to leak, which solves the disadvantages of the existing suturing device, makes the operation easier and improves the safety of the operation
