technical field

The utility model relates to the field of medical equipment, in particular to a hysteroscope with an electrode knife for treating patients under a visible state.

Background technique

Hysteroscopy is a light source endoscope mainly used for the inspection and treatment of the uterine cavity. It uses the front part of the mirror body to enter the uterine cavity. However, in the prior art, when examining the patient's uterus, it is usually necessary to extend the hysteroscope from the patient's body, enter the uterus, and observe the patient. treatment, or keep the hysteroscope in the patient's body, insert the treatment instrument into the patient's body at the same time, and treat the patient.

Chinese invention patent application CN103845032 discloses an electronic hysteroscope, which includes a hysteroscope body and a uterine cavity expansion component. The uterine cavity expansion component includes an expansion bag and a sleeve. The tail end of the casing is provided with a hook matching the fixing part on the handle, and the position of the expansion bag corresponding to the camera is set at the head end of the casing, and can cover the camera. The guide hole extending along its axial direction, the first end of the guide hole communicates with the expansion bag, and the tail end is bent outward to form an interface; the hysteroscope is equipped with a uterine cavity expansion component on the hysteroscope body. In the case of intrauterine conditions, the uterus can be expanded through the uterine cavity expansion component to obtain a larger observation range. However, this type of electronic hysteroscope still uses manual visual inspection to directly observe the patient’s intrauterine environment with the naked eye. During the examination, although the patient's uterine cavity is expanded, there are still some visual blind spots that cannot be directly observed, which is prone to misdiagnosis and missed diagnosis.

Similarly, Chinese invention patent application CN202497129 also discloses a hysteroscope, including a mirror tube, one end of the mirror tube is provided with an objective lens, and the other end of the mirror tube is connected with a main body, and the mirror tube includes a bent section and a straight line section, the bent section is provided with an objective lens and a prism, the straight line section is connected to the main body, and an imaging channel and a working channel parallel to each other are arranged in the mirror tube, and the imaging channel and the working channel run through the entire mirror tube, and the described The objective lens is located at the end of the imaging channel, a prism and an image transmission fiber are also arranged in the imaging channel, a light guide interface is arranged on the main body, a light guide is arranged in the light guide interface, and the light guide is located in the mirror tube. The hysteroscope uses mirrors arranged in the hysteroscope to reflect the light and the formed image, but can only perform a rough inspection of the patient's body by means of visual inspection.

To sum up, the hysteroscope in the prior art cannot treat the patient while carefully examining the patient, which is inconvenient.
