[0048] Embodiment 1: Figures 1 to 6 As shown, an embodiment of the present invention provides a sterile uterine manipulator capable of achieving multi-angle support, comprising a rod body 1, wherein the rod body 1 is provided with a uterine cavity support, a uterine lifting cup 3 and a vaginal seal 4 in sequence from top to bottom, the rod body 1 comprises a movable rod 11 and a fixed rod 12, a bending mechanism 7 is provided between the movable rod 11 and the fixed rod 12, the bending mechanism 7 is located between the uterine lifting cup 3 and the vaginal seal 4, and the bending mechanism 7 can make the movable rod 11 rotate around the end of the fixed rod 12;

[0049] The bending mechanism 7 includes a connecting sleeve 71, a rotating plate 72, an annular groove 73, and a connecting rod 74. The connecting sleeve 71 is flexible, and the two ends of the connecting sleeve 71 are respectively fixedly sleeved on the outer surfaces of the ends of the movable rod 11 and the fixed rod 12. The annular groove 73 is opened around the inner surface of the movable rod 11. A rotating plate 72 adapted to it is installed inside the annular groove 73, and the rotating plate 72 is arranged along the diameter of the annular groove 73. The connecting rod 74 is arranged at the center of the movable rod 11, and a sliding groove 75 is opened inside the movable rod 11. The rotating plate 72 is installed in the sliding groove 7 through a connecting shaft 76. 5, a pull rod 77 is provided at a position where the rotating plate 72 deviates from the connecting shaft 76, a groove is provided on the surface of the rotating plate 72, the top of the pull rod 77 is horizontally inserted into the groove, and the top of the pull rod 77 can move in the groove, and the top of the pull rod 77 can rotate with the rotating plate 72, one end of the pull rod 77 and the connecting rod 74 are extended to one end of the fixed rod 12 and are provided with a control mechanism 8, the control mechanism 8 is located at one end of the surface of the fixed rod 12 away from the movable rod 11, and the control mechanism 8 controls the rotation direction and angle of the movable rod 11 by controlling the movement of the rotating plate 72.

[0050] The control mechanism 8 includes a rotating seat 81, a rotating groove 82 and a handle 83. The rotating seat 81 has a rotating groove 82 on its surface that matches the fixed rod 12. The fixed rod 12 is installed in the rotating groove 82 at one end away from the movable rod 11. One end of the pull rod 77 passes through the rotating seat 81 and is fixedly connected to the handle 83. The pull rod 77 has limiting holes 85 distributed in a linear array on its surface along its moving direction. The fixed rod 12 is provided with a surrounding insertion hole 87 on its surface at the rotating groove 82. The rotating seat 81 has a limiting rod 86 inserted along its axial direction on its surface. The limiting rod 86 can be moved in or out from the limiting hole 85 and the insertion hole 87.

[0051] A return spring 84 is sleeved on the surface of the pull rod 77 located outside the rotating seat 81. One end of the return spring 84 is fixedly connected to the rotating seat 81, and the other end of the return spring 84 is fixedly connected to the handle 83. When the return spring 84 is in a natural state, the rotating plate 72 and the connecting rod 74 remain vertical.

[0052] The two sides of the lower outer surface of the fixing rod 12 are fixedly connected with handles 5 , and the handles 5 are arranged along the radial direction of the fixing rod 12 .

[0053] Specifically, the user holds the handle 5 with one hand and the rotating seat 81 with the other hand, and drives the connecting rod 74, the rotating plate 72 and the pull rod 77 to rotate axially around the fixed rod 12 by rotating the rotating seat 81, thereby adjusting the position of the rotating plate 72 and controlling the rotation direction of the rotating plate 72. In addition, the user can use one finger to pull the handle 83 at the same time to drive the pull rod 77 to move, so that the rotating plate 72 is tilted, thereby driving the movable rod 11 to bend, wherein the bending angle of the movable rod 11 is controlled by the moving distance of the pull rod 77. Finally, by setting a limit rod 86 to be inserted into the limit hole 85 and the socket 87, the pull rod 77, the rotating seat 81 and the connecting rod 74 are fixed, so that the movable rod 11 and the fixed rod 12 remain vertical or bent.

[0054] It should be noted that the inner diameter of the movable rod 11 is much larger than the outer diameter of the connecting rod 74 , and the gap between the connecting rods 74 can provide a certain movable space for the movable rod 11 . In addition, the material of the connecting sleeve 71 can be rubber, which can be deformed to ensure that the movable rod 11 can be bent relative to the fixed rod 12 .

[0055] In this embodiment, by setting up a control mechanism 8 and using it in conjunction with the bending mechanism 7, the movable rod 11 can be bent in various directions, so that the angle and direction of the movable rod 11 can be adjusted according to actual operation needs, thereby expanding the surgical field of view, expanding the surgical operation space, reducing the difficulty of surgical operations, and meeting various surgical needs.

[0056] It should be noted that: when the pull rod 77 drives the rotating plate 72 to tilt and the movable rod 11 and the fixed rod 12 are bent, the reset spring 84 undergoes elastic deformation; when the bent movable rod 11 and the fixed rod 12 need to be transformed into vertical movable rods 11 and fixed rods 12, it is only necessary to move the limiting rod 85 out of the limiting hole 86 and the insertion hole 87, and the reset spring 84 can drive the pull rod 77 to reset, so that the rotating plate 72 rotates back to be perpendicular to the connecting rod 74, thereby transforming the bent movable rod 11 and the fixed rod 12 into vertical movable rods 11 and fixed rods 12.

[0057] The vaginal seal 4 includes a cavity 41, an air hole 42, a sealing bag body 43 and an air supply pipe 44. The cavity 41 is opened on the inner wall of the fixing rod 12, the sealing bag body 43 is sleeved on the outer surface of the fixing rod 12, and the cavity 41 is located inside the sealing bag body 43. The air hole 42 is opened on the surface of the cavity 41, and the air hole 42 connects the sealing bag body 43 and the cavity 41. One end of the air supply pipe 44 is connected to the cavity 41, and the other end of the air supply pipe 44 is located on the outer side of the lower part of the fixing rod 12.

[0058] After the vaginal seal 4 is delivered into the vagina by the rod body 1, gas is delivered by the gas pipeline 44. The gas enters the sealing bag 43 through the gas pipeline 44, the cavity 41 and the air hole 42, so that the sealing bag 43 expands and fits against the inner wall of the vagina, thereby blocking the vagina and preventing gas leakage when cutting the vaginal wall.

[0059] The uterine cavity support member includes a cystic support member 2, which includes a supporting cystic body 21, a through hole 22, an air intake pipe 23 and a hollow tube 24. The hollow tube 24 is fixedly installed on the upper end of the movable rod 11, and the through holes 22 are evenly distributed on the surface of the hollow tube 24. The supporting cystic body 21 is sleeved on the outer surface of the hollow tube 24. The through hole 22 connects the supporting cystic body 21 and the hollow tube 24. One end of the air intake pipe 23 is connected to the end of the hollow tube 24, and the other end of the air intake pipe 23 is located on the outer side of the lower part of the fixed rod 12.

[0060] In this embodiment, after the uterine cavity support member is delivered into the uterus by the rod body 1, the gas is delivered by the air inlet pipe 23. The gas enters the support bladder 21 through the air inlet pipe 23, the hollow tube 24 and the through hole 22, causing the support bladder 21 to expand, thereby supporting the uterus.

[0061] Embodiment 2: Based on Embodiment 1, Figures 7 to 10 As shown, a uterine cavity support member with better supporting force is proposed, which includes a rod-shaped support member 6, and the rod-shaped support member 6 includes an electric push rod 61, an electromagnet 62, a pressure plate 63, a sleeve 64 and a telescopic rod 65. The electric push rod 61 is fixedly installed inside the fixed rod 12, and the telescopic end of the electric push rod 61 is fixedly connected to the electromagnet 62. The electric push rod 61 can move the electromagnet 62 at the upper end of the fixed rod 12, and the pressure plate 63 is fixedly installed at one end of the electromagnet 62 outside the fixed rod 12. The sleeve 64 is provided with two groups, and the two groups of sleeves 64 are both magnetic, and the two groups of sleeves 64 are rotatably installed on the upper end of the movable rod 11 through the rotating shaft 68. The power on and off of the electromagnet 62 controls the deflection of the sleeve 64. When the electromagnet 62 is powered off, the sleeve 64 deflects to both sides, and the pressure plate 63 can form a moving interference with the sleeve 64 in the rotation direction.

[0062] A telescopic rod 65 is provided inside the sleeve 64, and the telescopic rod 65 can move at the end of the sleeve 64 away from the rotating shaft 68. The end of the telescopic rod 65 located inside the sleeve 64 is fixedly connected to a piston, and the piston and the sleeve 64 are slidingly sealed. A telescopic spring 66 is sleeved on the outer surface of the part of the telescopic rod 65 located inside the sleeve 64, one end of the telescopic spring 66 is fixedly connected to the inner surface of the sleeve 64, and the other end of the telescopic spring 66 is fixedly connected to the piston part of the telescopic rod 65. The end of the sleeve 64 away from the telescopic rod 65 is connected with a connecting pipe 67, and the other end of the connecting pipe 67 is located on the outer side of the lower part of the fixed rod 12.

[0063] The rod-shaped support member 6 in this embodiment has a higher supporting force than the cystic support member 2. The rod-shaped support member 6 has two working states: folded and opened. The rod-shaped support member 6 in the folded state is easy to enter the uterine cavity, and the opened rod-shaped support member 6 is set to a T-shaped structure similar to the uterine structure, which can provide good support for the uterus. Specifically, the electric push rod 61 is used to make the electromagnet 62 extend out of the movable rod 11, and the power of the electromagnet 62 is turned on to make the electromagnet 62 generate magnetism, so that the electromagnet 62 can absorb the sleeve 64 and make the sleeve 64 fit on the surface of the electromagnet 62. This is the folded state of the rod-shaped support member 6; when the rod-shaped support member 6 needs to be switched to the opened state, it is only necessary to cut off the power of the electromagnet 62 to make the electromagnet 62 lose its magnetism, and then drive the electric push rod 61 to contract, so that the electromagnet 62 partially moves back to the movable rod 11. When the pressing plate 64 moves, the sleeve 64 will be pushed to deflect to both sides, and when the pressing plate 64 moves to the bottom of the sleeve 64, the pressing plate 63 will press on the surfaces of the two groups of sleeves 64, forming a moving interference with the sleeve 64 to prevent the sleeve 64 from deflecting. At this time, the two groups of sleeves 64 and the movable rod 11 form a T-shaped structure to support the uterus; when it is necessary to restore the rod-shaped support member 6 to the retracted state, the electric push rod 61 is extended to drive the electromagnet 62 to extend out of the movable rod 11, and the pressing plate 63 moves back with the movable rod 11, no longer pressing the sleeve 64, and then the electromagnet 62 is turned on again, and the electromagnet 62 is energized to attract the sleeve 64, so that the sleeve 64 rotates to the surface of the electromagnet 62, thereby completing the retraction of the sleeve 64.

[0064] In addition, gas is transported to the inside of the sleeve 64 through the connecting tube 67, and the gas can push the telescopic rod 65 to move out of the sleeve 64, so that the overall length of the horizontal part of the rod-shaped support member 6 in the open state, that is, the overall length of the sleeve 64 and the telescopic rod 65, can be adjusted, so as to support uteruses of different sizes, wherein the overall length of the sleeve 64 and the telescopic rod 65 is controlled by the input gas volume. During the movement of the telescopic rod 65, the telescopic spring 66 is compressed. After the operation, the gas can be extracted using the connecting tube 67. At this time, the compressed telescopic spring 66 is reset, driving the telescopic rod 65 to reset.

[0065] It should be noted that a battery assembly can be set inside the movable rod 11 or the fixed rod 12 to provide power to the electric push rod 61 and the electromagnet 62. A corresponding button can be set on the lower outer surface of the fixed rod 12. Pressing the button can control the switch of the electric push rod 61 or the electromagnet 62. The circuits and related driver programs involved are all existing conventional technologies and will not be repeated here.

[0066] The air inlet pipe 23 , the air delivery pipe 44 and the connecting pipe 67 are all provided with joints at one end outside the fixing rod 12 , and the joints can be connected to the external air delivery components.

[0067] The inner walls of the movable rod 11 and the fixed rod 12 are pre-opened with installation grooves adapted to the air intake pipe 23, the air delivery pipe 44 and the connecting pipe 67, and the air intake pipe 23, the air delivery pipe 44 and the connecting pipe 67 are respectively installed in the corresponding installation grooves.

[0068] In this embodiment, the external gas delivery component can be an existing micro air pump or other manual or automatic gas delivery equipment that can realize the gas delivery or gas extraction function. Among them, the joint needs to use an existing sealed detachable joint, such as a sealed threaded joint, etc., which will not be repeated here.

[0069] The specific working process of the technical solution provided by the present invention is as follows:

[0070] In actual use, the rod body 1 is inserted into the uterine cavity, so that the cup mouth of the uterine lifting cup 3 is close to the vaginal fornix, the uterine cavity support is used to fix and support the uterus, and the vaginal seal 4 is used to block the vagina. When the vaginal wall is cut during the operation, the vaginal seal 4 can effectively prevent the leakage of carbon dioxide gas;

[0071] In addition, the rotation direction and angle of the bending mechanism 7 can be controlled by the control mechanism 8 to adjust the angle of the uterus according to surgical needs to fully expose the surgical field of view.

[0072] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0073] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
