Description

Technical Field

[0001] The invention relates to the technical field of endoscopes, in particular to a portable hysteroscopic endoscope. Background Art

[0002] The portable hysteroscope is an innovative medical device designed to improve the convenience and efficiency of doctors in uterine cavity examination and treatment operations.

[0003] In the prior art, it is difficult for traditional hysteroscopes to flexibly change their overall length according to specific inspection needs. For hysteroscopes with longer structures, it is extremely inconvenient to carry and transport them. On the one hand, the excessive length makes it occupy a large space during storage and transportation, increasing logistics costs and storage difficulties. On the other hand, it is difficult to carry it to the scene conveniently during emergency medical rescue or primary medical services. At the same time, since its probe end is difficult to retract, it is easy to come into contact with other objects during transportation, which greatly increases the risk of bacterial infection. Once contaminated, the pathogens may be brought into the patient's body during uterine cavity examination, causing serious infection complications and posing a great threat to the patient's health. Secondly, the support mechanism of the traditional hysteroscope has a complex structure and is heavy, which is not convenient for doctors to carry between different places. During work, rapid installation or disassembly also becomes a problem, wasting precious medical time, reducing medical efficiency, and it is difficult to meet the needs of rapid diagnosis and treatment in emergency situations.
