In order to solve the technical problems, the technical scheme provided by the invention is as follows: a disposable electronic hysteroscope comprises a handle and an insertion tube arranged on the handle, wherein the handle comprises a knob, the inserting tube comprises a PVDF soft wrapping, a supporting outer tube and a rotating inner tube, the PVDF soft wrapping is wrapped outside the supporting outer tube, the supporting outer pipe is sleeved outside the rotating inner pipe, the rotating inner pipe is connected with the knob, one end of the inserting pipe, far away from the handle, is rotatably connected with a wire outlet pipe, the wire outlet pipe is connected with the rotary inner pipe, the wire outlet pipe is of an arc-shaped bent structure, the insertion pipe and the wire outlet pipe are both of oval structures, a lens is arranged in the end part of the wire outlet pipe far away from the insertion pipe, flushing water inlet holes are respectively arranged at two sides of the lens, a camera lens is arranged between the two flushing water inlet holes, the LED lamp is arranged on one side of the flushing water inlet and on two sides of the camera lens respectively, and the camera lens is provided with a working channel on one side far away from the flushing water inlet.

As an improvement, the bottom of the handle is also respectively provided with a water inlet pipe and a water outlet pipe, the water inlet pipe is connected with the two flushing water inlet holes, and the water outlet pipe is connected with the working channel.

As an improvement, the long axis of the outlet pipe is 4.8mm, and the short axis of the outlet pipe is 4.2 mm.

As an improvement, the bottom of the handle is also provided with a signal wire connector.

As an improvement, the bending angle of the outlet pipe is 22 degrees.

As an improvement, the supporting outer pipe and the rotating inner pipe are both made of stainless steel.

After adopting the structure, the invention has the following advantages: the visual field can be increased by rotating the head, and the soft foreskin and the supporting outer tube do not rotate while rotating inside, so that the soft foreskin and the supporting outer tube cannot rub against the internal cavity of the patient, and the pain of the patient is reduced; two wash the inlet opening water spray and come out through the camera, and the delivery water is siphoned away to working channel department, can wash the adnexed mucus on the camera totally, can effectively keep the definition on the camera. The working channel can enter surgical instruments while water is discharged, and the surgical instruments are not influenced mutually; the manufacturing cost of the optical fiber is reduced, the LED assembly process is simple, and the optical fiber is directly embedded into the corresponding hole; under the condition of keeping the size of the head of the prototype unchanged, the long end of the ellipse is increased, and the inner diameter of the working channel of the hysteroscope is increased.
