The right end of the airbag 12 is fixedly connected to the air tube 13. The right end of the air tube 13 is connected to the inflation device, which can be an electric air pump. The air tube 13 is a flexible hose. A pre-support limiting mechanism 2 for pre-positioning is provided on the right side of the airbag 12. The side wall of the tooling tube 11 is connected to the pre-support limiting mechanism 2. A scratch-resistant protection mechanism 3 to prevent scratching is connected to the side wall of the tooling tube 11.

[0035] The pre-support limiting mechanism 2 includes a driving component and a supporting component. The driving component for driving the supporting component to move is connected to the right end of the side wall of the tooling tube 11; the supporting component for pre-positioning is connected to the left end of the driving component, and the driving component is connected to the side wall of the tooling tube 11.

[0036] In this invention, the support component is driven to move by the drive component, so that the support component is pre-positioned. At this time, the air tube 13 inflates the inside of the balloon 12, so that the balloon 12 expands outward and fits against the cervical sidewall to achieve a seal, thereby preventing leakage of distension fluid from affecting the use of the hysteroscope. At this time, the hysteroscope passes through the inside of the tool tube 11 to perform surgical operations. The pre-positioning of the support component prevents the balloon 12 from causing the device to shift when it expands, thus affecting the sealing effect. The anti-scratching protection mechanism 3 protects the cervical sidewall and prevents the device from scratching the cervical sidewall when it moves.

[0037] Example 2: In some embodiments, please refer to the accompanying drawings. Figures 1-6 The drive assembly includes a sleeve 211, a fixed ring block 212, and a movable ring block 213. The sleeve 211 is threadedly connected to the side wall of the tooling tube 11; the fixed ring block 212 is fixedly connected to the side wall of the tooling tube 11; and the movable ring block 213 is rotatably connected to the sleeve 211.

[0038] The support assembly includes a telescopic rod 221, a telescopic rod 222, a scissor bar 223, a scissor bar 224, and a support rod 225. Multiple telescopic rods 221 arranged in a uniform circular array are fixedly connected to the right end of the fixed ring block 212; multiple telescopic rods 222 are fixedly connected to the left end of the movable ring block 213, with each telescopic rod 221 corresponding to a different telescopic rod 222; the right end of each telescopic rod 221 is slidably connected to the left end of each telescopic rod 222; and the side wall of the fixed ring block 212 is rotatably connected to... Multiple scissor lift rods 223 arranged in a uniform circular array; multiple scissor lift rods 224 are rotatably connected to the side wall of the movable ring block 213, with each scissor lift rod 223 corresponding to a scissor lift rod 224; the middle part of each scissor lift rod 223 is hinged to the middle part of the corresponding scissor lift rod 224; the end of each scissor lift rod 223 away from the tooling tube 11 is hinged to the right inner end of the support rod 225, and the end of each scissor lift rod 224 away from the tooling tube 11 is hinged to the left inner end of the support rod 225; the side wall of the support rod 225 is provided with an arc surface.

[0039] In this invention, rotating sleeve 211 drives movable ring block 213 to move closer to fixed ring block 212, telescopic rod 222 slides inside telescopic rod 221, and at the same time, scissor rod 223 and the end of scissor rod 224 move closer together and drive support rod 225 to move outward. The arc surface of the side wall of support rod 225 fits against the cervical side wall. By supporting the cervical side wall with multiple support rods 225, the device is pre-limited, thereby ensuring that the device will not deviate when the airbag 12 is inflated through the trachea 13, and improving the sealing effect of airbag 12.

[0040] Example 3: In some embodiments, please refer to the accompanying drawings. Figures 1-6 The anti-scratch protection mechanism 3 includes a first protective block 31, a second protective block 32, and a protective cloth 33. The first protective block 31 is fixedly connected to the side wall of the tooling tube 11 and is located at the left end of the fixed ring block 212. The second protective block 32 is fixedly connected to the right end of the movable ring block 213 and is rotatably connected to the sleeve 211. The left end of the first protective block 31 and the right end of the second protective block 32 are provided with an inclined surface. The protective cloth 33 is sleeved on the side wall of multiple support rods 225. The left end of the protective cloth 33 is sleeved on the left inclined surface of the first protective block 31, and the right end of the protective cloth 33 is sleeved on the right inclined surface of the second protective block 32.
