Description

Technical Field

[0001] The utility model mainly relates to the technical field of gynecological medical instruments, in particular to a hysteroscope tube body structure with high replacement efficiency. Background Art

[0002] Hysteroscopy is a new minimally invasive gynecological diagnosis and treatment technology. It is a fiber-light endoscope used for intrauterine examination and treatment. It includes a hysteroscope, energy system, light system, perfusion system and imaging system. It uses the front part of the scope to enter the uterine cavity, which has a magnifying effect on the observed area. It has become the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions because of its intuitive and accurate nature. Hysteroscopy can not only determine the location, size, appearance and range of the lesions, but also make detailed observations of the tissue structure on the surface of the lesions.

[0003] During the use of the hysteroscope, the outlet pipe supplies water to the uterine cavity, and the return pipe draws out the sewage in the uterine cavity through the return hole, so that the inside of the uterine cavity remains clean, so that the camera can observe the situation inside the uterine cavity normally and medical personnel can perform surgery. However, many products on the market currently have low sewage replacement efficiency, only one return hole, and are easily blocked. The total reflux area is not larger than the outlet area, and the reflux speed is low. The used sewage cannot be discharged from the uterine cavity quickly, which contaminates the camera, affects the camera's observation effect, and is not conducive to surgical operations.
