Description

Hysteroscope operation auxiliary device

Technical Field

The application relates to the field of hysteroscopic surgery, in particular to a hysteroscopic surgery auxiliary device.

Background

The general flow of the hysteroscopic surgery is as follows: opening the well-regulated monitoring system and the uterus dilating device; turning on the power supply of the uterus expanding pump, connecting the uterus expanding device with the surgical instrument, and discharging gas in the connecting pipeline; under the set pressure, such as uterus swelling liquid, after the liquid flowing out of a drainage hole of the endoscope body is clear, the endoscope body is pushed into the uterus, and observation is carried out after the uterine cavity is fully expanded; the operation is performed by using a scalpel.

Hysteroscopic scissors are a device used to open intrauterine adhesions in order to recreate the normal uterine cavity morphology. Because the scissors need to penetrate through the endoscope body, the angle adjustment is limited; in the operation, the conglutination at the uterine corner needs to be completely cut, and the uterine corner and the uterine fundus are completely exposed so as to establish a relatively normal uterine cavity shape; therefore, the existing scissors have the defects of small angle adjusting range and difficult shearing of uterine horn adhesion.

In addition, the ideal uterine-expanding pump at present is driven by rollers, and can adjust the pressure and flow rate of the output uterine-expanding liquid; when the uterine cavity is started, air in the uterine cavity needs to be discharged completely so as to avoid air embolism of veins; however, it is still impossible to ensure that the gas is present in the uterus swelling liquid which is subsequently input.
