Electronic hysteroscope

Abstract

The invention discloses an electronic hysteroscope. The electronic hysteroscope comprises a hysteroscope body and a uterine cavity expansion assembly; the uterine cavity expansion assembly comprises an expansion capsule and a cannula; the cannula is arranged on an extension rod in a sleeving mode; a hook portion which is matched with a fixing part arranged on a handle is arranged corresponding to the tail end of the cannula; the position of the expansion capsule, which is corresponding to a camera, is located at the head end of the cannula and can cover the camera; the cannula wall of the cannula is provided with a guide hole which extends along the axial direction of the cannula wall; the head end of the guide hole is communicated with the expansion capsule; the tail end of the guide hole bends towards the outer side to form a connection opening. According to the electronic hysteroscope, the design is skillful, the structure is reasonable, the hysteroscope body is provided with the uterine cavity expansion assembly and accordingly a uterus can be expanded through the uterine cavity expansion assembly in the case of observation of the uterus so as to obtain a large observation range, and accordingly changes of portions of the uterus can be accurately and rapidly understood, the accuracy of the diagnosis is greatly improved, and the safety and the efficiency of surgery are ensured.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an electronic hysteroscope. Background technique [0002] At present, hysteroscopy and hysteroscopy technology have been widely used clinically, and are important tools for gynecological diagnosis and treatment of diseases. With existing hysteroscopy, the perfusion system needs to be activated before the operation, and the perfusion system is directly injected into the uterus. The gas or liquid expands the uterus, and the gas or liquid directly contacts the inner wall of the uterus, and easily penetrates the inner wall of the uterus and enters the patient's circulatory system. This will cause many complications, such as: injury, bleeding, infection, complications of CO2 uterine distension, cardio-cerebral syndrome, uterine perforation, etc., resulting in surgical accidents. Contents of the invention [0003] The purpose of the present invention is to address the above shortc...
