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

Abstract

The invention relates to the technical field of medical instruments, and discloses a laparoscopic instrument with a sound-absorbing structure, including a Veress needle, a sound-absorbing element and a protective case, a sound-absorbing disc is arranged between the fixed blocks, and the sound-absorbing element Both ends are provided with a first internal thread, the exterior of the sound-absorbing member is provided with a fixing ring, the inside of the fixing ring is provided with a second internal thread, and the surface of the sound-absorbing member at the position of the fixing ring is provided with a second An external thread, a cross bar is installed inside the protective shell, a sphere is sleeved on the cross bar, and a return spring is sleeved on the cross bar on one side of the sphere. This kind of endoscopic instrument with sound-absorbing structure, by setting the fixed ring, the sphere and the return spring, makes the present invention have the function of convenient disassembly and assembly and the function of preventing the loss of gas, without the need of external flow-blocking equipment, and at the same time, it is convenient for users to disassemble and disassemble. The sound parts are cleaned, and the interior is cleaned to effectively keep the noise-absorbing parts clean, prevent patients from being infected, and improve the success rate of the operation.

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...
