Suture type minimally invasive fascia stitching instrument having double anti-slip mechanism

Abstract

The invention relates to the technical field of medical instruments, and specifically relates to a suture type minimally invasive fascia stitching instrument having a double anti-slip mechanism. The stitching instrument includes a stitching instrument body, a self-locking mechanism arranged in the stitching instrument body, a clamping mechanism used for clamping suture needles, and a push rod mechanism used for pushing the suture needles; the top and bottom of the stitching instrument body are respectively provided with a stitching instrument body upper cover and a stitching instrument body end head; the stitching instrument body is provided with a channel chamber; the stitching instrument body upper cover is provided with a clamping groove; and a lower gear jacking seat is arranged in theclamping groove, and provided with multiple first ratchets having inclined surfaces. The stitching instrument body can penetrate into subcutaneous tissues; the self-locking mechanism can be opened tomake wing plates at the bottom of the stitching instrument body unfolded; the push rod mechanism can penetrate suture lines into the suture needles; the clamping mechanism can clamp silica gel pads,so that the suture needles can pass through the silica gel pads; and the stitching instrument body can be pulled out, and the knotting of the suture lines can be accomplished. The stitching instrumentis convenient and safe in operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a suture type minimally invasive fascial stapler with a double anti-slip mechanism. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgical method. Compared with traditional surgery, it has the advantages of small incision, fast recovery and less pain. It is an inevitable trend in the development of future surgical methods. At present, more and more patients accept it. Treatment for this surgery. [0003] At present, during laparoscopic surgery, it is necessary to set up 3 to 5 puncture channels with a size of 5 to 10 mm in diameter to penetrate the abdominal wall tissue, so that surgical instruments can enter the abdominal cavity or thoracic cavity through these puncture channels to perform surgery; , These puncture channels need to be sutured so that the wound can heal smoothly. However, generally during use, due to the trac...

Problems solved by technology

However, generally during use, due to the traction of muscle tissue or sutures, the sutures clamped by the silicone pad of the traditional fascia suturing device are easy to fall off, resulting in poor suture surgery, affecting the suture effect and the later healing effect; and The traditional fascia suturing device needs to be controlled by hand at all times to maintain the opening and closing state of the flaps during the opening and closing process of the flaps, which takes up excess manpower, and it is impossible to achieve consistent opening and closing of the flaps by directly pulling and controlling the flaps, and it is easy to use force If it is too large or too small, it will cause damage to the flap or the failure of the suture needle to penetrate the flap, etc.
