Referring to fig. 1 to 8, the bending system of the disposable electronic hysteroscope according to the preferred embodiment of the present invention includes a disposable electronic hysteroscope 10 and a bending device 20. The disposable electronic hysteroscope 10 includes a handle 11 and a sheath 12 mounted to the handle 11. The bending device 20 comprises a base 21, two support columns 22 arranged on the base 21 at intervals, and an extrusion column 23 arranged on the base 21, wherein the extrusion column 23 and the two support columns 22 are arranged in a triangle; in an initial state, a receiving space 24 is formed between the pressing post 23 and the two supporting posts 22, and the distal end of the sheath 12 is adapted to be placed in the receiving space 24. The distal end of the sheath 12 can be extruded to be bent to a predetermined shape during the movement of the extrusion column 23 toward the gap between the two support columns 22.
An operator can bend the distal end of the sheath tube 12 of the disposable electronic hysteroscope 10 to a preset shape based on the degree of bending of the uterine cavity of the patient by using the bending device 20, so that the disposable electronic hysteroscope 10 can better adapt to the shape of the uterine cavity of the patient, and the better uterine cavity examination or uterine cavity operation effect is achieved.
The two support columns 22 and the extrusion columns 23 are arranged in a substantially triangular shape, after the distal end of the sheath tube 12 is mounted in the accommodating space 24, the two support columns 22 and the extrusion columns 23 are respectively abutted against three different positions of the sheath tube 12, and the movement of the extrusion columns 23 in the direction of the gap between the two support columns 22 can be controlled to control the preset shape of the distal end bending value of the sheath tube 12 so as to be convenient for adapting patients with different Gong Qiangqu degrees.
Before bending the sheath 12 using the bending device 20, the operator can use "double-diagnosis" to initially determine whether the uterine cavity of the patient is anteflexion or retroflexion, and approximately, the degree of flexion, and then control the movement of the compression column 23 to control the bending of the distal end of the sheath 12 to a predetermined shape.
Referring to fig. 1, further, a first accommodating groove 220 is formed on a side of the support column 22 near the extrusion column 23, a second accommodating groove 230 is formed on a side of the extrusion column 23 near the two support columns 22, a portion of the distal end of the sheath 12 corresponding to the support column 22 is mounted in the first accommodating groove 220, and a portion of the distal end of the sheath 12 corresponding to the extrusion column 23 is mounted in the second accommodating groove 230, so as to improve stability of the distal end of the sheath 12 in the bending process.

Before the extrusion column 23 moves towards the gap between the two support columns 22, the extrusion column 23 corresponds to a first scale mark on the first set of scale marks 211, after the extrusion column 23 moves towards the gap between the two support columns 22 for a certain distance, the extrusion column 23 corresponds to a second scale mark on the first scale mark 211, and the distance of the extrusion column 23 moving towards the gap between the two support columns 22 can be determined through the difference between the first scale mark and the second scale mark.

The support columns 22 are provided with mounting positions, two ends of the molding strip 30 are mounted at two mounting positions of two support columns 22, and an operator can conveniently determine the bending degree of the sheath tube 12 in the process that the extrusion column 23 bends the sheath tube 12 towards the clearance movement between the two support columns 22. Placing the molding strips 30 corresponding to the degree of the uterine cavity of the patient on the two support columns 22 allows the operator to intuitively compare the bending degree of the sheath 12 with the bending degree of the molding strips 30, so as to facilitate rapid bending of the distal end of the sheath 12 in place.

Preferably, the first screw 251 and the second screw 252 are connected to the two support columns 22 by means of spherical hinges.
Further, the base 21 is provided with a second set of graduation marks 212 along a straight line where the two support columns 22 are located.

The tube body surrounds and forms accommodation space, the baffle install in accommodation space, and with accommodation space is divided into camera lens storehouse and apparatus storehouse. Preferably, the connection part of the partition plate and the inner wall of the pipe body is fixed in a manner of welding and dispensing, so that water leakage at the connection part of the partition plate and the pipe body in the bending process is prevented. It should also be noted that the connection between the diaphragm and the two support columns 22 needs to be arranged substantially parallel during bending, so that the diaphragm can better follow the bending of the pipe body.
