Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a kind of sheath tube abdominal wall anastomat. BACKGROUND

[0002] Minimally invasive laparoscopic surgery of human body has gradually replaced traditional surgery and is widely applied in general surgery, gynecology and cardiothoracic surgery because of its advantages of small trauma, small physiological disturbance to patients, light pain and fast recovery. In laparoscopic surgery, the doctor first uses a puncture device to penetrate the abdominal wall of the patient, then pulls out the puncture cone on the puncture device, and performs surgery through the puncture cannula left on the abdominal wall of the patient as a channel for surgical instruments to enter and exit the human body. After the surgery is completed, the doctor needs to suture the puncture holes and the epidermis after removing the puncture cannula. However, due to the small incision and deep inner wall of the puncture hole, the suturing operation is difficult. The current solutions include manual suturing and fascial suture device suturing. Manual suturing is suitable for thin patients, but for obese patients, the abdominal wall tissue is too thick to satisfy the accurate and effective suturing of the puncture incision, which easily leads to a series of complications such as bleeding, infection, puncture hole hernia and injury. Although the fascial suture device suturing can suture the fascia of obese patients, the puncture device needs to be pulled out first, and then the fascial suture device is operated, which is complicated and increases the risk of infection for patients.
