Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fascia stapler. Background Art

[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. With the development of the medical beauty industry, laparoscopic surgery has gradually been used in the medical beauty industry. During laparoscopic surgery, 3 to 5 puncture channels with a diameter of 5 to 12 mm that penetrate the abdominal wall tissue need to be set up first, so that the laparoscope and surgical instruments can enter the abdominal cavity or thoracic cavity through these puncture channels to perform surgery. After the operation is completed and the surgical instruments are removed, these puncture channels need to be sutured to allow the wound to heal smoothly.

[0003] In recent years, with the widespread application of laparoscopic surgery, postoperative suturing has become a major problem. At present, fascia staplers are generally used for postoperative suturing. The existing fascia staplers are basically composed of a cylindrical shell, a pull rod, a cylindrical driving handle, and flip-up wings connected to the lower end of the shell and the lower end of the pull rod. However, the needle tip is exposed when passing through the wing, which can easily be inserted into the patient's organs, posing a great safety hazard.

[0004] After searching, a safe fascia stapler disclosed in patent publication number CN209153812U can solve the technical problems existing in the prior art fascia stapler, but there are still certain disadvantages in use. The device needs to be inserted into the abdominal cavity when in use. After being inserted into the abdominal cavity, the surgeon needs to control the expansion and contraction of the wings through a control rod. However, the control rod slides in the shell in a push-pull manner. In this push-pull manner, it is not easy for the surgeon to control the push-pull speed of the control rod, and it is easy to push and pull the control rod too fast, thereby causing the wings to expand or contract too quickly, causing pain to the patient. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a fascia stapler that enables surgical personnel to control the speed of a control rod more easily, makes the control rod slide more slowly, avoids the control rod sliding too fast, effectively avoids the wings from expanding or contracting too quickly, and prevents pain to the patient.
