Endoscope instrument with silencing structure

Abstract

The invention relates to the technical field of medical instruments, and discloses an endoscope instrument with a silencing structure. The endoscope instrument comprises a pneumoperitoneum needle body, a silencing piece and a protective shell. A silencing disc is arranged between the fixing blocks; first internal threads are arranged in the two ends of the silencing piece, a fixing ring is arranged outside the silencing piece, a second internal thread is arranged on the inner side of the fixing ring, a first external thread is arranged on the surface of the silencing piece at the position of the fixing ring, a cross rod is installed inside the protective shell, a ball body is arranged on the cross rod in a sleeving mode, and a reset spring is arranged on the cross rod on one side of the ball body in a sleeving mode. The invention discloses an endoscope instrument with a noise elimination structure. By arranging the fixing ring, the ball body and a reset spring, the endoscope instrumenthas the functions of being convenient to disassemble and assemble and preventing gas loss, external flow blocking equipment is not needed, meanwhile, a user can disassemble and assemble the silencingpiece conveniently and clean the interior of the silencing piece, the silencing piece is effectively kept clean, the infection phenomenon of a patient is avoided, and the success rate of an operationis increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a laparoscopic device with a sound-absorbing structure. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. It has greatly increased the chances of surgical selection. Compared with traditional surgery, laparoscopic surgery is very popular among patients, especially because the postoperative scar is small and meets the aesthetic requirements. Young patients are more willing to accept it. Minimally invasive surgery is the general...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a laparoscopic instrument with a sound-absorbing structure, which has the advantages of convenient disassembly and assembly and the function of preventing gas loss, and solves the need for the existing pneumoperitoneum operation during the operation process. Inflate the patient's body, and harsh noises will be produced during the inflating process, which will affect the hearing of the medical staff and hinder the implementation of the operation. After inflating, it is necessary to prevent the loss of gas in the patient's body. Usually, the external cover is insufflated The end of the needle, but this operation increases the workload, and part of the gas in the patient's body will be lost, and at the same time, blood and water in the patient's body will be drawn into the Veress needle, which is inconvenient to clean
