Embodiment Construction

[0029] The embodiments will be described in detail hereinafter, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following examples do not represent all implementations consistent with this application. These are merely examples of systems and methods consistent with aspects of the present application as recited in the claims.

[0030] In the technical solution provided by the present application, the sealing member is used in conjunction with an endoscope. The endoscope is an optical instrument, generally composed of a cold light source lens, a fiber optic wire, an image transmission system, a screen display system, and the like. The endoscope can be used to directly observe the inside of the human body and the cavities inside the organs, and the insid...

Abstract

The invention provides a sealing element for a clamp path f an endoscope. The sealing element comprises a valve body, a first one-way valve and an elastic ring belt, wherein the first one-way valve isarranged in the valve body and connected with the inner wall of the valve body through the elastic ring belt. The elastic ring belt is thin and soft, so that the deformation degree of the elastic ring belt is larger than that of the first one-way valve, and the first one-way valve can swing in the valve body. When a treatment instrument moves, the first one-way valve can correspondingly swing along with the treatment instrument, so that the first one-way valve can tightly wrap the treatment instrument all the time, the sealing performance of the clamp path of the endoscope is improved, gaps are prevented, liquid backflow is stopped, and the problems that a traditional sealing element easily produce gaps in surgical operation to cause liquid backflow are solved.

Description

technical field [0001] The present application relates to the technical field of medical instruments, in particular to an endoscope channel seal. Background technique [0002] Endoscope is an optical instrument commonly used in minimally invasive surgery, including rigid endoscope and soft endoscope. Among them, in the flexible endoscopic equipment, there will be provided a pipeline through which instruments such as surgical forceps pass, and the pipeline is called the forceps channel of the endoscope. During endoscopic clinical operations, body fluids, medicinal liquids and other liquids in the body cavity will flow back along the clamp channel of the endoscope, enter the clamp channel, and even overflow from the upper opening of the endoscope, affecting the surgical operation . The returned liquid may also adhere to the endoscopic instrument and be carried out, which may easily induce the risk of infection. Therefore, in order to reduce the backflow of liquid, a sealing...
