[0020] like Figure 1 and Figure 2As shown, the distance adjustment mechanism includes a mounting frame 11, a ball bearing 13, a moving rod 15, a limit slide 151, a distance adjustment screw 16 and a distance adjustment knob 161; the mounting frame 11 is connected to the support seat 1; the mounting frame 11 is rotatably connected to the ball bearing 13; the distance adjustment screw 16 is screwed to the ball bearing 13 through an internal thread structure; the moving rod 15 is rotatably connected to the distance adjustment screw 16; two limit slides 151 are fixedly connected to the moving rod 15; the two limit slides 151 are slidably connected to the ball bearing 13 together; the distance adjustment knob 161 is fixedly connected to the distance adjustment screw 16; the moving rod 15 is fixedly connected to the center column 2; the moving rod 15 and the inside of the distance adjustment screw 16 are rotatably connected to the fine-tuning shaft 17 together.

[0021] like Figure 3 As shown, a folding sheath 42 is fixedly connected between the curved portion of the guide rod 41 and the sleeve 4, and the folding sheath 42 covers the connection area between the guide rod 41 and the sleeve 4; the diameter of the sleeve 4 is larger than the diameter of the guide rod 41, and after the guide rod 41 is successfully inserted into the uterus, the sleeve 4 with a larger diameter can be firmly inserted at the entrance of the uterus; the folding sheath 42 is configured as a conical structure that contracts toward the curved portion of the guide rod 41, so as to reduce the movement resistance encountered by the folding sheath 42 during the insertion of the curved portion of the guide rod 41 into the uterus.

[0022] In the use steps of a quick-adjustable multifunctional uterine manipulator of the present invention, the user first places the support seat 1 on the operating table, and allows the uterine lifting cup and the guide rod 41 to be between the patient's legs. The user then manually adjusts the distance adjusting screw 16 to drive the ball bearing 13 to rotate vertically in the up and down directions, and adjusts the up and down inclination angles of the uterine lifting cup and the guide rod 41 connected to the distance adjusting screw 16 until the up and down inclination angles of the uterine lifting cup and the guide rod 41 are aligned with the patient's vaginal inclination angle. The user then rotates the distance adjusting knob 161 forward to drive the distance adjusting screw 16 to rotate. During the rotation of the distance adjusting screw 16 along the internal thread of the ball bearing 13, the distance adjusting screw 16 pushes the moving rod 15 to drive the limiting slide rod 151 to slide along the ball bearing 13, so that the moving rod 15 drives the uterine lifting cup and the guide rod 41 to be smoothly inserted into the patient's vagina along their current inclination direction until the guide rod 41 is inserted into the patient's uterus, and the uterine lifting cup covers the uterus at the same time.

[0023] During this process, the user slowly rotates the fine-tuning knob 171 forward to drive the fine-tuning shaft 17 and the first fine-tuning screw 172 and the second fine-tuning screw 173 connected thereto to rotate synchronously, and the rotating first fine-tuning screw 172 pushes the movable plate 34 to drive the telescopic frame 35 to approach the fixed plate 3, and at the same time, the telescopic frame 35 pushes the fixed cup petals 32 outward along the inclined slide rail 31 on the fixed plate 3, and at the same time, the fixed cup petals 32 pull the telescopic frame 35 outward along the movable plate 34, so that all the fixed cup petals 32 are in an outwardly expanded state together, and all the fixed cup petals 32 push all the contracted cup petals 33 outward. The guide rod 41 is stretched to increase the overall diameter and length of the uterine lifting cup until it can completely cover the outside of the uterus to adapt to uteruses of different sizes. At the same time, the rotating second fine-tuning screw 173 pushes the guide rod 41 to move outward along the sleeve 4. At the same time, the guide rod 41 drives the folding sheath 42 to stretch in the moving direction, so that the length of the guide rod 41 that can be inserted into the uterus can also increase, so that the guide rod 41 can adapt to the corresponding lengths of uteruses of different sizes, so that the guide rod 41 and the uterine lifting cup can firmly fix the uterus together, making it convenient for the user to perform subsequent hysterectomy.

[0024] After the user finishes the hysterectomy, the user slowly reverses the fine-tuning knob 171 to drive the fine-tuning shaft 17 and the first fine-tuning screw 172 and the second fine-tuning screw 173 connected thereto to rotate synchronously, and the first fine-tuning screw 172 pulls the moving plate 34 to drive the telescopic frame 35 to move in the opposite direction, so that the telescopic frame 35 drives the overall diameter and length of the uterine lifting cup to shrink, so that the shrunken uterine lifting cup clamps the covered uterus, and at this time, the second fine-tuning screw 173 will also pull the guide rod 41 to move inward along the sleeve 4, so that the guide rod 41 inserted into the uterus also shrinks, but due to The shrinking change caused by the uterine lifting cup and the guide rod 41 is small, so there is no situation where the guide rod 41 cannot adapt to the length of the uterus, ensuring that the guide rod 41 and the uterine lifting cup can continue to firmly fix the uterus together, and at this time the uterus will be more firmly grasped in the uterine lifting cup, and then the user will reversely rotate the distance adjustment knob 161 to drive the distance adjustment screw 16 to rotate, and let the distance adjustment screw 16 pull the moving rod 15 to move the uterine lifting cup and the guide rod 41 in the opposite direction, so that in the subsequent step of removing the uterine lifting cup and the guide rod 41 from the vagina to remove the uterus, the uterus is not easy to fall off from the uterine lifting cup and the guide rod 41.

[0025] Example 2 On the basis of Example 1, Figure 1-Figure 7As shown, the curved portion of the guide rod 41 of this embodiment is set as a hollow structure, and four through-grooves 410 structures penetrating inside and outside are opened on the guide rod 41; an inflatable airbag 5 is inserted into the internal hollow structure of the curved portion of the guide rod 41, and the inflatable airbag 5 is set as a curved structure corresponding to the structure of the curved portion of the guide rod 41; the inflatable airbag 5 is provided with a convex structure corresponding to the number and position of the through-grooves 410 structure, and the convex structure of the inflatable airbag 5 is plugged into the corresponding through-grooves 410 structure. A telescopic pipe 51 is connected to the inflatable airbag 5, and the inflatable airbag 5 is set as a structure in which the convex structure on the upper side has a thick wall and the convex structure on the lower side has a thin wall; a fixing ring 1 is fixedly connected to the sleeve 4. 8; A compressed air bag 19 is fixedly connected to the fixing ring 18, and the compressed air bag 19 is sleeved on the outer surface of the guide rod 41; an air delivery pipe 191 is fixedly connected between the compressed air bag 19 and the telescopic pipe 51; pressurized gas is initially stored between the compressed air bag 19 and the expansion air bag 5; the outer surfaces of all protruding structures of the expansion air bag 5 are provided with anti-slip stripe structures; the outer surfaces of all protruding structures of the expansion air bag 5 are initially set to be arc structures aligned with the outer surface of the guide rod 41, so that the protruding structures of the expansion air bag 5 will not initially protrude from the outer surface of the guide rod 41, thereby reducing the friction resistance of the protruding structures of the expansion air bag 5 when moving with the guide rod 41 in the vagina.

[0026] When the user inserts the guide rod 41 into the uterus, when the user slowly turns the fine-tuning knob 171 forward to drive the guide rod 41 to move outward along the sleeve 4, the guide rod 41 pushes the compressed airbag 19 to be compressed in the direction of the fixed ring 18, so that the pressurized gas in the compressed airbag 19 successively passes through the gas delivery pipe 191 and the telescopic pipe 51 into the expansion airbag 5, so that all the protruding structures of the expansion airbag 5 are propped outward by the pressurized gas, so that the guide rod 41 can be firmly inserted by relying on the protruding structures propped outward on the expansion airbag 5. Inside the uterus, and because the wall of the protruding structure on the lower side of the inflation airbag 5 at one end away from the sleeve 4 is set to be thinner than the rest of the inflation airbag 5, after all the protruding structures of the inflation airbag 5 are propped up by the pressurized gas, the end of the protruding structure on the lower side of the inflation airbag 5 away from the sleeve 4 will present a bulge structure with a larger volume than the surrounding protruding structures, allowing the guide rod 41 to be stuck in the uterine cavity in the form of a barb through the bulge structure of the inflation airbag 5, further preventing the guide rod 41 from loosening or even falling off from the inside of the uterus to the outside.

[0027] Example 3 On the basis of Example 1, Figure 1-Figure 5As shown, the mounting frame 11 of the present embodiment is slidably connected to the support seat 1; the support seat 1 is rotatably connected to a height-adjusting screw rod 12; the height-adjusting screw rod 12 is screwed to the mounting frame 11 through a threaded structure; a height-adjusting knob 121 is fixedly connected to the height-adjusting screw rod 12; the user only needs to rotate the height-adjusting knob 121 to drive the height-adjusting screw rod 12 to rotate, and the rotating height-adjusting screw rod 12 can drive the mounting frame 11 to adjust the angle in the up and down directions along the support seat 1, so that the uterine lifting cup and the guide rod 41 connected to the mounting frame 11 are aligned with the height of the vagina, thereby completing the height adjustment process.

[0028] A vertical angle adjustment motor 14 is installed on the mounting frame 11, and a self-locking mechanism is provided inside the vertical angle adjustment motor 14; the ball bearing 13 is composed of a fixed part and a movable part, the fixed part of the ball bearing 13 is fixedly connected to the mounting frame 11, the movable part of the ball bearing 13 is screwed to the pitch adjustment screw 16 through a threaded structure, the movable part of the ball bearing 13 is slidably connected to the limit slide rod 151, and the movable part is rotatably connected to the fixed part through a rotating shaft, so that the movable part of the ball bearing 13 can only be adjusted in the vertical angle in the up and down directions; the output shaft of the vertical angle adjustment motor 14 is fixedly connected to the movable part of the ball bearing 13 ; The user only needs to operate the vertical angle adjustment motor 14 to control the movable parts of the ball head bearing 13 to perform vertical angle adjustment in the up and down directions, thereby driving the uterine lifting cup and the guide rod 41 connected to the ball head bearing 13 to rotate until the inclination angle of the vagina is relatively aligned, completing the vertical angle adjustment process. Then the user turns on the self-locking mechanism of the vertical angle adjustment motor 14 after the angle adjustment work is completed, so that the movable parts of the ball head bearing 13 can be locked and can no longer move in the up and down directions, so that the uterine lifting cup and the guide rod 41 connected to the ball head bearing 13 are locked in the current vertical angle placement state.

[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
