[0034] Embodiment 1

[0035] Reference Figure 1-Figure 4 , a uterine manipulator, comprising a first positioning plate 1, wherein a rotating column 5 is rotatably connected inside the first positioning plate 1, and a second positioning plate 2 is fixed outside the rotating column 5 and located on the top of the first positioning plate 1, so that the first positioning plate 1 and the second positioning plate 2 are rotatably connected through the rotating column 5, and when the rotating column 5 is positioned inside the first positioning plate 1, the angle between the first positioning plate 1 and the second positioning plate 2 is positioned, and an expansion rod 4 is fixed at one end of the first positioning plate 1 and the second positioning plate 2, and a hand-held rod 3 is fixed at the other end of the first positioning plate 1 and the second positioning plate 2, so that the two hand-held rods 3 are moved away from each other to drive the corresponding expansion rod 4 to move through the first positioning plate 1 or the second positioning plate 2, and the uterus is observed by the movement of the two expansion rods 4 away from each other;

[0036] A positioning mechanism for limiting the rotation of the rotating column 5 is installed inside the first positioning plate 1, and the positioning mechanism includes a translation plate 8, a positioning column 9, a limit motor 10, a limit disk 11 and a connecting rod 12. The first positioning plate 1 is internally and slidably connected to one end of the rotating column 5 with the translation plate 8, and the positioning column 9 is fixed to one end of the translation plate 8 close to the rotating column 5, so that the translation plate 8 slides inside the first positioning plate 1, allowing the positioning column 9 to enter the inside of the rotating column 5. When the positioning column 9 is located inside the rotating column 5, the rotating column 5 cannot rotate. A limit motor 10 is fixed inside the first positioning plate 1, and the output end of the limit motor 10 is connected to the limit disk 11. The top of the limit disk 11 is rotatably connected to one end of the translation plate 8 close to the translation plate 8 with the connecting rod 12, and the connecting rod 12 is rotatably connected to the translation plate 8, so that the rotation of the limit disk 11 drives the translation plate 8 to move through the connecting rod 12;

[0037] In this embodiment, there are three positioning columns 9 , which are arranged vertically. In other embodiments, a plurality of vertical positioning columns 9 may be provided according to the stability of limiting the rotation column 5 .

A charging port is opened inside one side of the first positioning plate 1 and at a position corresponding to the battery 6. A sealing gasket 7 is slidably connected to one side of the first positioning plate 1 and at a position corresponding to the charging port, and the charging port is protected by the sealing gasket 7.

[0039] The use process of the uterine lifter provided by the utility model is as follows: when the uterus needs to be lifted and opened for observation, firstly, two closely attached expansion rods 4 are extended into the interior of the uterus, and then the two hand-held rods 3 are moved apart, so that the hand-held rods 3 drive the corresponding expansion rods 4 to move through the first positioning plate 1 or the hand-held rods 3, so that the two expansion rods 4 are moved apart, and then the uterus is opened, and at the same time, the uterus is lifted by the height of the expansion rods 4. When the uterus is opened to a certain angle by the two expansion rods 4 being moved apart, the limit motor 10 is energized to drive the limit plate 11 to rotate, and the rotation of the limit plate 11 drives the connecting rod 12 to rotate and move, and the rotation of the connecting rod 12 drives the rotatably connected translation plate 8 to slide inside the first positioning plate 1, and the translation plate 8 drives the positioning column 9 to move, so that the positioning column 9 enters the interior of the slidingly connected rotating column 5, and the rotation of the rotating column 5 is limited.

[0042] The limiting mechanism includes a height support plate 15, an arc-shaped rotating rod 17, an extrusion block 18, an arc-shaped positioning block 19, an anti-slide plate 21, a guide slider 22 and a compression spring 23. The interior of the height support plate 15 is slidably connected to the sliding column 14, so that the height support plate 15 can be lifted and slid by sliding on the outside of the sliding column 14. At the same time, the height support plate 15 can be separated from the sliding column 14 through the sliding connection. The interior of one side of the height support plate 15 is rotatably connected with the arc-shaped rotating rod 17, and an extrusion surface 20 is provided on one side of one end of the arc-shaped rotating rod 17, so that the arc-shaped rotating rod 17 located on the inner side of the height support plate 15 can be opened through the extrusion surface 20. The top and bottom of one end of the arc-shaped rotating rod 17 are fixed with an arc-shaped positioning block 19, and a positioning groove 24 is provided inside the height support plate 15 and at a position corresponding to the arc-shaped positioning block 19, so that the arc-shaped rotating rod 17 is positioned by the overlap of the arc-shaped positioning block 19 and the positioning groove 24 when the inner side of the height support plate 15 rotates;

[0044] The use process of the uterine manipulator provided by the utility model is as follows: when the height of the first positioning plate 1 needs to be positioned, the first positioning plate 1 is allowed to allow the sliding column 14 to enter the interior of the rotating column 5 through the sliding connection with the rotating column 5 before use, and then when the first positioning plate 1 and the second positioning plate 2 are opened, the top of the height support plate 15 in the limiting mechanism at the bottom of the first positioning plate 1 is brought into contact with the first positioning plate 1, and at the same time, the bottom of the height support plate 15 in the limiting mechanism at the top is brought into contact with the second positioning plate 2, and then the arc-shaped rotating rod 17 in the height support plate 15 is rotated toward the inner side of the height support plate 15 through the rotating connection, so that The rotation of the arc-shaped rotating rod 17 squeezes the anti-slip plate 21 through the squeezing block 18, so that the anti-slip plate 21 is guided by the sliding of the guide slider 22 to allow the anti-slip plate 21 to enter the inner side of the sliding column 14 of the sliding connection, and limit the height of the height support plate 15. At the same time, the movement of the anti-slip plate 21 squeezes the compression spring 23, and allows the arc-shaped rotating rod 17 to enter the interior of the positioning groove 24 through the arc-shaped positioning block 19 for positioning. When the height of the height support plate 15 needs to be adjusted, the arc-shaped rotating rod 17 is squeezed by the squeezing surface 20 to make the arc-shaped rotating rod 17 rotate in the opposite direction, and then the anti-slip plate 21 is reset by the rebound after being compressed by the compression spring 23.
