It is a fiber-light endoscope used for examination and treatment within the uterine cavity, including a hysteroscope, an energy system, a light source system, a perfusion system and an imaging system. It uses the front part of the scope to enter the uterine cavity, which has a magnifying effect on the observed area, making it the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions with its intuitive and accurate nature.

[0003] For example, the Chinese utility model (publication number CN216495232U) discloses a leak-proof hysteroscope for gynecological and obstetric examinations, including a hand-held tube, a sleeve, a tube head, a leak-proof component, an inspection component and other structures. This technical solution can prevent the uterine fluid from flowing out along the outer wall of the sleeve, has an excellent sealing effect, prevents the uterine fluid from flowing out from the inside of the sleeve, prevents internal leakage and external leakage, avoids the uterine fluid from affecting hygiene, and improves the inspection efficiency and effect. The device has a simple structure, is easy to use, and is highly practical.

[0004] However, the above technical solution still has the following technical problems in actual use: the leaked uterine fluid is collected by a leak-proof cover, but the leak-proof cover is buckled on the outside of the patient, and the sealing effect is effective. Excessive leakage of uterine fluid will accumulate in the leak-proof cover. As the uterine fluid accumulates, the excessive uterine fluid is very likely to leak out of the leak-proof cover. A large amount of uterine fluid accumulated in the leak-proof cover is also inconvenient for medical staff to operate the hysteroscope, which is inconvenient to use. Utility Model Content
