[0085] Such as Figure 7 As shown, the difference between the third embodiment of the present invention and the first embodiment and the second embodiment is that the water inlet 16 is located on the front end face of the insertion tube 11, and the water outlet 17 is located on the front end side of the insertion tube 11. Therefore, since the common configuration has already been described in the above description, redundant description will be omitted.

[0086] The water outlet 17 is positioned at the side of the front end of the insertion tube 11, so that there is a certain distance between the water inlet 16 positioned on the end face of the front end port, so that the water flow is injected into the human body from the water inlet 16 and is immediately discharged from the water outlet 17 next to it. Such setting is beneficial to increase the distance of water circulation, improve cleaning efficiency and save cleaning time.

[0087] In summary, the straight channel hystero...

Abstract

The invention discloses a straight channel hysteroscope, comprising an insertion part and an operation part, the insertion part includes an insertion tube and an imaging module seat fixed at the front end of the insertion tube; the operation part is connected to the end of the insertion part through a rigid connector, It includes a handle and a handle at a certain angle with the handle; the front end port of the insertion part is provided with a first instrument outlet, and the rear end of the handle is provided with a first instrument inlet. The instrument channel communicates with the first instrument outlet, and the acute angle between the axis of the first instrument inlet section and the axis of the first instrument channel is less than 15 degrees. The straight channel hysteroscope of the present invention can make the optical fiber hardly need to be bent during the process of extending from the entrance of the instrument channel. Since the optical fiber itself is brittle and easy to break, it can effectively prevent the optical fiber from passing through the instrument channel entrance and the instrument channel. The optical fiber is damaged due to bending in between, thereby improving the operation efficiency and having good practical value.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a straight channel hysteroscope. Background technique [0002] Hysteroscope is a kind of light source hysteroscope mainly used for examination and treatment of uterine cavity. It uses the front part of the mirror body to enter the uterine cavity. It has become the preferred inspection method for gynecological hemorrhagic diseases and intrauterine lesions with intuitiveness and accuracy. 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. [0003] The utility model patent with application number CN201520128034.9 discloses an endoscope with a high-frequency ultrasonic probe, including an insertion...
