Puncture sleeve device for laparoscope puncture set

Abstract

The invention relates to a puncture sleeve device for a laparoscope puncture set. The puncture sleeve device comprises a puncture sleeve body and a two-stage sealing device, the puncture sleeve body comprises a puncture sleeve seat and a sleeve, the two-stage sealing device is mounted above the puncture sleeve seat, the sleeve is mounted below the puncture sleeve seat, an air injection valve is mounted on the side wall of the puncture sleeve seat, and the air injection valve and the puncture sleeve are integrated. The two-stage sealing device comprises a first sealing component and a second sealing component, and the first sealing component is positioned above the second sealing component. The specification of the puncture sleeve of the puncture sleeve device is 10mm, the puncture sleeve is matched with the puncture set and can directly take out tissues cut in an operation, an extra puncture channel can be decreased, injury to patients is reduced, and the puncture sleeve device is convenient to use, safe and reliable.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a puncture sleeve device for a laparoscopic trocar. Background technique [0002] In minimally invasive human medical surgery, once a disease is found in the human body, surgery or resection is required. During the operation, the puncture device is first used. The puncture device is a kind of operation that pierces the abdominal wall and enters the body cavity for other surgical instruments. An instrument belongs to a minimally invasive surgical instrument. A trocar usually includes a sleeve assembly serving as an access channel for other surgical instruments and a puncture rod penetrating through the sleeve assembly. First, in order to penetrate the skin, cut the epidermis of the skin with a scalpel, then use the puncture rod to penetrate the skin and enter the body cavity together with the sleeve assembly, and then pull out the puncture rod, the sleeve assembly can be used t...

AI Technical Summary

Problems solved by technology

[0003] In the process of establishing pneumoperitoneum, air leakage between the outer sheath and the incision site of human tissue often occurs, resulting in the failure of pneumoperitoneum establishment; During the whole operation, the doctor will constantly adjust the insertion angle of the puncture device according to the needs of the operation and take out or insert the surgical instruments reciprocally, which will also cause the puncture device to slip off and leak air; The puncture needle is also equipped with an exposed blade. Since the blade with the puncture head is always exposed, it is easy to accidentally injure the internal organs of the human body after entering the incision of human tissue.

[0004] In addition, in a typical gynecological operation, the puncture channel needs to be established to facilitate the removal of the cut uterine tissue. In the prior art, an additional puncture channel of 15mm needs to be established, which will cause greater harm to the patient.
