Abdominocentesis stitching instrument

Abstract

The invention relates to an abdominocentesis stitching instrument. The abdominocentesis stitching instrument comprises a puncture sheath, a puncture core, a puncture seal assembly and a puncture thread take-off needle which can be assembled together sequentially. The seal assembly is embedded inside an inlet part of the puncture sheath, locating passages are formed in the sidewall of the inlet part of the puncture sheath, a gas inlet part is arranged below the inlet part of the puncture sheath, and a tube sheath part has an adhesive film, a circular hole, a helical structure and a concave structure; a rotary button, a spring, a small slope and a fixed column are arranged in a head part of the puncture core, a body part has a big slope connected with a link below, and the link is downwardlyconnected with a cutter blade; the seal assembly is composed of a sealing gasket A and a sealing gasket B, of which both comprise arc-shaped bottom walls, vertical side walls and lugs, the arc-shapedbottom walls are connected to bottoms of the vertical side walls, and the lugs are connected to tops of the vertical side walls; and the puncture thread take-off needle comprises a puncture needle, aneedle cylinder, a spanner, a needle core, a baffle, a pintle and a spring. The needle cylinder is connected with the puncture needle and then is connected with the spanner, a proximal end of the needle core penetrates through the spring and the baffle and then is connected with the pintle, and a distal end of the needle core has grabbing teeth. According to the abdominocentesis stitching instrument, one instrument has the functions of abdominocentesis and puncture hole stitching.

Description

technical field [0001] The invention relates to a deep tissue puncture and stapler of the body cavity wall, which belongs to a medical device, and is suitable for suturing and closing a laparoscopic puncture hole. Suture device. 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 present invention. In the process of laparoscopic minimally invasive surgery, it is first necessary to puncture the body cavity to e...

Problems solved by technology

[0003] An existing deep fascia puncture device (Patent No. 201420690583.0 and Patent No. 20161059430.4) is two different sets of instruments from the paracentesis and needs to be used separately. On the one hand, the cost of the instrument is increased, and on the other hand, the use process is more cumbersome

(Patent No. 201811504192.4) provides a suture pattern with a side hole on the puncture core and a clip at the distal end. On the one hand, it increases the difficulty of making the puncture core, and on the other hand, it is difficult to suture small puncture holes.
