AI Technical Summary
The anterior longitudinal ligament of the sacrum is located in the retroperitoneum. Due to the obstruction of the intestines, its position is relatively hidden and deep. When the mesh is sutured and fixed under laparoscopy, it is difficult to accurately control the direction of the suture needle and it is easy to injure other organs, nerves and blood vessels of the patient. The suturing is difficult and prolongs the operation time.
A suturing device comprising a shell, a connecting plate, a suture seat, a hook, and a reset assembly is designed. The hook hook catches the suture and the angle of the suture seat changes under the action of the reset spring, ensuring that the suture accurately passes through the mesh and the anterior longitudinal ligament, and quickly completes the fixation.
This method enables accurate and rapid suturing during sacral fixation, reducing the risk of injury to other organs, nerves, and blood vessels, and shortening the operation time.
