Specifically, the rotary diverter 5 includes a horizontally arranged diverter body 56, the diverter body 56 is a hollow pipe structure, and the pipe wall of the diverter body 56 is provided with a first water inlet and outlet 52 and a second water inlet and outlet 53, wherein the first water inlet and outlet 52 is connected to the first water valve 32, and the second water inlet and outlet 53 is connected to the second water valve 33. Specifically, the third interface 324 of the first water valve 32 is connected to the first water inlet and outlet 52, and the sixth interface 334 of the second water valve 33 is connected to the second water inlet and outlet 53, thereby forming a passage between the external water inlet pipe or the drainage pipe and the inside of the hysteroscope.

[0048] Further, the rotary diverter 5 also includes a rotating shaft 54 ​​horizontally arranged inside the rotary diverter 5, and a rotating driving structure is provided at one end of the rotating shaft 54 ​​to drive the rotating shaft 54 ​​to perform axial rotational movement in the rotary diverter 5.

Further, one end of the rotating shaft 54 ​​is fixed to the rotating handwheel 51, and the other end is fixed to the rear end of the front tube 6. Thus, the rotating shaft 54 ​​divides the rotary diverter 5 into a first waterway channel 57 and a second waterway channel 58 that are isolated from each other. When working, the first water valve 32, the first water inlet and outlet 52 and the first waterway channel 57 form a waterway, and the second water valve 33, the second water inlet and outlet 53 and the second waterway channel 58 form another waterway. The front tube 6 can be controlled to rotate by operating the rotating handwheel 51.

[0049] Furthermore, a sealing plug 4 is provided between the diverter body 56 and the rotating hand wheel 51 to prevent the liquid from flowing into the rotating hand wheel 51. Specifically, one end of the rotating shaft 54 ​​is connected to the rotating hand wheel 51 and then passes through the sealing plug 4 and extends toward the front pipe 6.

[0053] A light source device 63 and a camera assembly 66 are led out from the data line channel 61 at the front end of the front tube 6. Furthermore, the rotating shaft 54 ​​extends and is fixed inside the camera channel 61 of the front tube 6. When the rotating hand wheel 51 is turned, the rotating shaft 54 ​​drives the front tube 6 to rotate, thereby driving the rotation of the camera assembly 66, providing medical personnel with image information at different angles during surgery or examination. During operation, the medical instrument is inserted through the rear end of the front tube 6 (not shown in the figure) and passed through the working channel 62 to perform corresponding surgical treatment on the patient.

[0054] Furthermore, a connector 7 is provided between the insertion tube 6 and the diverter body 56 to further tighten and prevent water leakage.

When the first water path is filled with water, the water flow direction enters the first interface 322 from the external water pipe and then flows into the first water path channel 57 through the third interface 324 and the first water inlet and outlet 52, and then enters the interior of the uterine cavity through the third water path channel 64 of the front tube 6. Conversely, the first water path The drainage direction is that the uterine cavity discharge fluid enters the third water channel 64 from the front end opening of the front tube 6, passes through the first water channel 57, the first water inlet and outlet 52 and the third interface 324, and then goes to the external drainage pipe from the second interface 323; when the second water channel is filled with water, the water flow direction is from the external water pipe into the fourth interface 332, then passes through the sixth interface 334 and the second water inlet and outlet 53 to enter the second water channel 58, passes through the fourth water channel 68 of the front tube 6 to enter the inside of the uterine cavity; conversely, the drainage direction of the second water channel is that the uterine cavity discharge fluid enters the fourth water channel 68 from the front end opening of the front tube 6, passes through the second water channel 58, the second water inlet and outlet 53 and the sixth interface 334, and is discharged from the fifth interface 333 to the external drainage pipe.
