Novel hysteroscope

Abstract

The invention discloses a novel hysteroscope. The novel hysteroscope comprises a hysteroscope body, a hysteroscope sheath, a liquid outlet, a liquid inlet and an operation channel device, wherein thehysteroscope body, the liquid outlet, the liquid inlet and the operation channel device are arranged on the hysteroscope sheath; the operation channel device comprises a channel body, an upper end cover, a waterproof cap and a waterproof flap, wherein one end of the channel body communicates with the hysteroscope sheath, the other end of the channel body is connected with the upper end cover witha middle through hole, the waterproof flap and the waterproof cap are arranged in the channel body and the upper end cover, the waterproof flap and the waterproof cap are both hollow, the lower end ofthe waterproof flap is composed of at least two flap films, the upper end of the waterproof flap is inserted into the lower end of the waterproof cap, and the outer diameter of the waterproof cap isequal to the inner diameter of the channel body in dimension. According to the novel hysteroscope, in hysteroscope surgery, when a surgical instrument extends into the uterine cavity or is taken out,a valve can be opened or closed without auxiliary of others, a uterine distending medium can also be prevented from squirting out from an operation hole during surgery, in this way, the operation steps in the surgery are simplified, constancy of the uterine distending pressure is further ensured, and the success rate of the hysteroscope surgery is increased.

Description

technical field [0001] The invention relates to a novel hysteroscope. Background technique [0002] The development of hysteroscopy has a history of more than 100 years. Since the era of hysteroscopic surgery in 1978, the development has advanced by leaps and bounds, and various hysteroscopes have emerged in an endless stream. Performing hysteroscopic surgery generally needs to simultaneously inject a certain pressure of uterine distention fluid into the uterus. In order to prevent the uterine distention fluid from ejecting from the operating hole of the surgical instrument, the current hysteroscope is provided with a manual valve near the operating hole of the surgical instrument. It is very inconvenient for the doctor to open and close the valve with the assistance of others when entering and exiting the instrument during the operation; due to the high pressure in the uterine cavity, the uterine distension fluid is easily ejected from the operation hole, which not only ea...

AI Technical Summary

Problems solved by technology

It is very inconvenient for the doctor to open and close the valve with the assistance of others when entering and exiting the instrument during the operation; due to the high pressure in the uterine cavity, the uterine distension fluid is easily ejected from the operation hole, which not only easily causes insufficient uterine distention pressure, but also affects the surgical field of view, thus Increase the difficulty of the operation, and even cause the operation to fail, bringing great pain to the patient
