Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Combination Figure 1 and Figure 2 As shown, a balloon-type uterine lifter with an anti-penetration structure includes a handle 1 and a lifting rod 2 fixedly connected to one end of the handle 1. A balloon 3 is provided at the end of the lifting rod 2 away from the handle 1. It also includes a lifting cup 4 and a cup holder assembly 5 abutting against the end of the lifting cup 4. The lifting cup 4 and the cup holder assembly 5 are slidably sleeved on the lifting rod 2. The cup holder assembly 5 is also provided with a fastening component 6. A pad 7 is provided between the fastening component 6 and the lifting rod 2. The fastening component 6 is indirectly pressed onto the lifting rod 2 through the pad 7.

[0021] In this invention, during use, the uterine lifter 2 is slowly inserted into the uterus, and then the cup holder assembly 5 is pushed so that the uterine cup 4 is pushed along the uterine lifter 2 to the desired position. The fastening assembly 6 is then indirectly pressed onto the uterine lifter 2 via the pad 7, thus fixing the cup holder assembly 5 to the uterine lifter 2. Therefore, this invention adds a pad 7 between the fastening assembly 6 and the uterine lifter 2. The fastening assembly 6 is indirectly pressed onto the uterine lifter 2 via the pad 7 to prevent oblique shearing force from being applied to the surface of the uterine lifter 2 during the fastening process, thus preventing damage to the heat shrink tubing on the surface of the uterine lifter 2.

[0022] like Figure 1As shown, the cup holder assembly 5 includes a housing 51, one end of which has an abutment surface 52. The uterine cup 4 can be pressed onto the abutment surface 52. A through hole 53 is provided on the abutment surface 52, through which the uterine support rod 2 passes. The sliding housing 51 supports and abuts the uterine cup 4 via the abutment surface 52, thereby fixing the position of the uterine cup 4.

[0023] Combination Figure 2 and Figure 3 As shown, the pad 7 includes a pad body 71. One side of the pad body 71 is pressed against the surface of the lifting rod 2, and the other side is pressed against the fastening assembly 6. The contact area between the pad body 71 and the lifting rod 2 is larger than the contact area between the pad body 71 and the fastening assembly 6. This increases the actual force-bearing area on the surface of the lifting rod 2 and reduces the pressure it receives.

[0024] like Figure 3 As shown, the pad 7 also includes a wing 72 fixedly connected to the side of the pad body 71, and the outer shell 51 is also provided with a straight groove 54. The end of the wing 72 away from the pad body 71 extends into the straight groove 54. The wing 72 and the straight groove 54 cooperate with each other and can guide the pad body 71 during its up and down movement.

[0025] Preferably, two wings 72 are provided and symmetrically located on both sides of the gasket body 71, and the straight grooves 54 are provided in a one-to-one correspondence with the wings 72. This ensures that the guiding force is evenly applied to the gasket body 71.

[0026] like Figure 3 As shown, the fastening assembly 6 includes a drive part 61 and an adapter part 62 that are fixedly connected. The adapter part 62 is rotatably connected to the outer shell 51 via a pin 63. The adapter part 62 is also provided with a pressing block 64 that protrudes radially along the adapter part 62. Rotating the adapter part 62 can press the pressing block 64 onto the surface of the pad 7.

[0027] In use, the user applies external force to the drive unit 61, causing the drive unit 61 and the adapter 62 to rotate around the pin 63. During rotation, the clamping block 64 acts on the pad body 71, and the pad body 71 moves downward under pressure to press against the surface of the lifting rod 2. Thus, the oblique shear force generated by the clamping block 64 during rotation only acts on the pad body 71, and the positive pressure transmitted to the surface of the lifting rod 2 through the pad body 71 is positive pressure.

[0028] Preferably, the fastening assembly 6 further includes a protruding flange 66 to facilitate the application of external force by the user. The protruding flange 66 is fixedly connected to the side of the drive unit 61 away from the adapter 62. The protruding flange 66 facilitates the user's application of force to the drive unit 61.

[0029] like Figure 3As shown, a locking block 55 is also fixedly installed on the outer shell 51. The end of the locking block 55 is arc-shaped, and the maximum diameter of the arc is greater than the width of the locking block 55. The bottom of the driving part 61 is provided with a locking groove 65 that matches the locking block 55. Rotating the adapter 62 allows the locking block 55 to be embedded in the locking groove 65. The locking block 55 and the locking groove 65 cooperate with each other to fix the driving part 61 after rotation, preventing the driving part 61 from loosening during use and causing the cup 4 and cup holder assembly 5 to be unsecured.

[0030] like Figure 2 As shown, the cup holder assembly 5 is also fitted with an annular sealing bladder 8, which is connected to the catheter 9. The end of the catheter 9 furthest from the annular sealing bladder 8 is also connected to an indicator bladder 10. This invention also provides an annular sealing bladder 8 on the uterine lift rod 2, which allows for better sealing of the pneumoperitoneum. During surgery, the external indicator bladder 10 can be used to indicate the inflation or deflation status of the annular sealing bladder 8 inside the patient's body, allowing the user to directly observe it.
