Safe fascia stapler and method of use

Abstract

The invention provides a safe fascia stapler and a method of use, which solve the technical problems of the prior art such as large hidden danger of safety and the like. The fascia stapler comprises ahousing; the housing is provided with a folding transformation structure; the folding transformation structure is connected with the folding control structure; the housing is provided with a guide channel for the suture guide needle to penetrate; an axial direction of the guide channel is offset from the axial direction of the housing; a soft cushion for insertion of a suture guide needle is arranged on the folding transformation structure. The soft cushion is arranged corresponding to the guide channel when the folding transformation structure is in the unfolded state; the folding transformation structure comprises a plurality of spanner wings hinged on the lower end of the housing, the soft cushion is arranged on the spanner wings, and one end of each spanner wings away from the lower end of the housing is hinged with a limiting protector. Suture-guided needle penetrating abdominal wall tissue into the abdominal cavity, and then through the soft cushion, and finally the needle tip against the limiting protector, so that the needle tip will not be inserted into the patient's organs or tissues, increasing the safety of fascia tissue suture surgery, which can better protect patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a safety type fascial stapler and a usage method. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgical method. Compared with traditional surgery, it has the advantages of small incision, quick recovery and less pain. During laparoscopic surgery, 3 to 5 puncture channels with a diameter of 5 to 12 mm need to be set up to penetrate the abdominal wall tissue, so that the laparoscope and surgical instruments can enter the abdominal cavity or thoracic cavity through these puncture channels to perform surgery. At the end of the operation, after removing the surgical instruments, these puncture channels need to be sutured so that the wound can heal smoothly. [0003] In recent years, with the widespread use of laparoscopic surgery, postoperative suturing has become a major issue. At present, fascial staplers are genera...

AI Technical Summary

Problems solved by technology

Existing fascial staplers are basically composed of a cylindrical housing, pull rod, cylindrical driving handle, and reversible wings connected to the lower end of the housing and the lower end of the pull rod. However, the needle tip is exposed when passing through the wings, which is easy to insert. To the patient's organs, a greater safety hazard
