Puncture sheath of abdominal puncture suture device

Abstract

The invention relates to a puncture sheath of an abdominal puncture suture device, belongs to medical instruments, and is suitable for abdominal wall puncture and puncture hole suture closing in laparoscopic surgery. The puncture sheath comprises an inlet part, an air inlet part and a tube sheath part; a clamping groove is formed above the inlet; positioning channels are formed in the side wall; the air inlet part is arranged below the side wall; a sealing assembly is embedded in the inlet part; the far end is connected with the tubular tube sheath part; the tube sheath part is provided with adhesive films, round holes, a spiral structure and a concave structure; the two positioning channels are symmetrically distributed on the outer side wall of the inlet part; downward and inward inclined lines are positioned on the same straight line corresponding to the round holes of the tube sheath part and the near end of the concave structure respectively; the air inlet part comprises an air inlet and a choke valve; the round holes are formed in the near end of the tube sheath part; the round holes are symmetrically distributed; and the surfaces of the round holes are covered with the adhesive films. By improving an original air inlet part, puncture of an abdominal wall can be completed; and an abdominal wall puncture hole also can be sutured through a puncture thread hooking needle.

Description

technical field [0001] The invention relates to a body cavity wall tissue puncture and stapler, which belongs to medical equipment, and is suitable for abdominal wall tissue puncture during laparoscopic surgery and suturing and closing of puncture holes after surgery. A device for completing body cavity puncture and postoperative puncture hole suturing. Background technique [0002] In the surgical process, laparoscopic minimally invasive technology has been widely used and widely used in various fields such as thoracic surgery, abdominal surgery, urology and gynecology. Laparoscopic minimally invasive technology not only has less trauma, but also avoids the traditional large incision at the surgical site , It also makes the operation part more beautiful, and the patient can leave the bed earlier without worrying about the incision dehiscence, which speeds up the recovery of the patient after the operation. Now take laparoscopic surgery as an example to illustrate the prese...

Problems solved by technology

Existing laparoscopic instruments usually pull out each puncture device after the laparoscopic operation is completed, and then suture each puncture hole. Because the abdominal wall is thicker, the puncture hole is narrow and deep, and if you want to manually suture the peritoneum or deep muscle tissue Difficult, often time-consuming surgical procedure and incomplete closure

[0003] An existing deep fascia stapler (application number 201610569430.4) is two different sets of instruments from the paracentesis and needs to be used separately. On the one hand, the cost of surgical instruments is increased, and on the other hand, the use process is relatively cumbersome
