Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figure 1-2 As shown, the medical insertion tube includes a spring inner tube 1, which has a helical structure and is made of coiled spring sheets. A metal mesh pipe 2 is sheathed on the spring inner pipe 1, and the metal mesh pipe 2 is a stainless steel metal mesh pipe. A sleeve 3 is sheathed on the metal mesh pipe 2, and the sleeve is a polyurethane tube.

[0019] A sheath 4 is sheathed on the sleeve 3, and the length of the sheath 4 is shorter than the length of the sleeve 3. An installation area 5 is formed at both ends of the sheath 4 and the two ends of the sleeve 3 respectively. In the two installation areas 5 One of the installation areas 5 is connected with a connection sleeve 6 with one end against the corresponding end of the sheath 4, the installation area 5 is provided with an annular groove and is arrang...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a medical intubation tube. The problem that the prior art is unreasonable in design is solved. The medical intubation tube comprises a spring inner tube, the spring inner tube is sleeved with a metal net tube, the metal net tube is sleeved with a sleeve, and the sleeve is sleeved with a sheath shorter than the sleeve; two installing regions are formed at the two ends of the sheath and the two ends of the sleeve respectively, one installing region is connected with a connecting sleeve with one end abutting against the corresponding end of the sheath and provided with an annular groove and a sealing sleeve which is arranged in the annular groove and located between the annular groove and the connecting sleeve, the other end of the connecting sleeve is suspended, and an inner thread is arranged on the inner wall of the suspended end of the connecting sleeve. The medical intubation tube has the advantages of being good in seal performance and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a medical insertion tube. Background technique [0002] Medical insertion tubes include gastroscope insertion tubes, colonoscopy insertion tubes, choledochoscope insertion tubes, and the like. These tubes are made by weaving metal wire. [0003] For example, gastroscopy is currently the best method for diagnosing gastrointestinal diseases. Ordinary gastroscopy is an intubation-type inspection method. It uses a thin, flexible tube to extend into the stomach, and doctors can directly observe gastrointestinal lesions. However, the design of the existing insertion tube is not reasonable enough, the connection structure between the insertion tube and the equipment has low strength, poor sealing performance and prone to air leakage, and secondly, it is not easy to install and connect. Contents of the invention [0004] The object of the present invention is to solve the...
