Embodiment Construction

[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] combine Figure 1-3 As shown, an anti-bending waterway connection structure includes an outer casing 1 and an endoscopic tube 2 connected to the outer casing 1. The outer casing 1 is provided with a water inlet joint 3 and a water outlet joint 4. The endoscopic tube 2. One end away from the outer casing 1 has a water inlet 5 and a water return port 6, and a relatively independent first water inlet hose 7 and a second water inlet hose 8 are arranged between the water inlet joint 3 and the endoscopic tube 2, so The first water inlet hose 7 is communicated with the second water inlet hose 8, one end of the first water inlet hose 7 is communicated with the water inlet joint 3, and one end of the second water inlet hose 8 is connected to the endoscopic tube 2. and communicated with the water inlet 5, the water outlet joint 4 and the ...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an anti-bending waterway connecting structure. In order to solve the problems that in the prior art, a cavity dividing type waterway structure is complex in whole and not easy to set, large force needs to be applied during rotation due to the fact that a large number of sealing rings are used for sealing, and operation is not convenient, the invention provides an anti-bending waterway connecting structure which comprises an outer shell and an endoscopic tube connected to the outer shell. A water inlet connector and a water outlet connector are arranged on the outer shell, a water inlet and a water return port are formed in the end, away from the outer shell, of the endoscopic pipe, a first water inlet hose and a second water inlet hose which are relatively independently arranged are arranged between the water inlet connector and the endoscopic pipe, and the first water inlet hose and the second water inlet hose are communicated. One end of the first water inlet hose is communicated with the water inlet joint. The waterway is erected in a hose connection mode, so that a large number of sealing rings do not need to be arranged in the hysteroscope to guarantee sealing of an inner cavity, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an anti-bending waterway connection structure. Background technique [0002] Hysteroscopy is a new, minimally invasive gynecological diagnosis and treatment technology. It is an endoscope for the examination and treatment of the uterine cavity. It is easy to observe and diagnose the entire uterine cavity, and the examination process is fast, painless, and non-invasive Uterus. During hysteroscopic surgery, it is necessary to inject water into the uterus through the hysteroscope to enlarge the uterine cavity and facilitate the observation of the operation process. [0003] Most of the waterway systems in the prior art adopt a split-cavity structure, combined with Figure 5 As shown, its interior includes two first chamber a and second chamber b separated by sealing ring c, and the two waterway ports of endoscope d are communicated with the first chamber a and t...
