[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the lithotomy surgical tripod of this embodiment includes a base plate 1 and a support assembly. The base plate 1 is used to erect the entire device or to fix it to other fasteners (such as an examination table). Therefore, mounting holes 19 can be opened on the base plate 1, and fixing bolts 20 that can be threaded into the mounting holes 19 are matched therein. The fixing bolts 20 can fix it to other fasteners. Of course, other connection methods (such as clamping) are also applicable. The support assembly is used to support and raise the lower limbs of the human body, so that they are in the "lithotomy position". Since the human body normally has two lower limbs, two lithotomy surgical tripods of this embodiment should be set up in actual use, which can be set on the left and right sides of the examination table respectively.

[0024] The main components of the support assembly include a threaded column 2, a lifting plate 3, a rotating plate 4, and a limiting rod 11. The threaded column 2 is vertically and rotatably connected to the base plate 1. The lifting plate 3 is threadedly connected to the threaded column 2. The rotating plate 4 is rotatably connected above the lifting plate 3. The limiting rod 11 is vertically connected to the base plate 1 and passes through the lifting plate 3.

[0025] Combined Figure 2 and Figure 3 The threaded column 2 is a cylindrical column with external threads and a certain rigidity. Its connection with the base plate 1 is as follows: the end of the base plate 1 is provided with a bearing hole 9, and a bearing 7 is fixedly connected in the bearing hole 9 by an interference fit. When connected, the threaded column 2 passes through the bearing 7 and is fixedly connected to the inner circle of the bearing. This setting allows the threaded column 2 to rotate freely.

[0026] To better control the rotation of the threaded post 2, a rotating plate 17 is fixedly connected to the lower end of the threaded post 2, and a handle 18 is fixedly connected to the lower part of the rotating plate 17. To maximize rotational efficiency, the connection point of the threaded post 2 to the rotating plate 17 is located at one end of the upper plane of the rotating plate 17, and the connection point of the handle 18 to the rotating plate 17 is located at the other end of the lower plane of the rotating plate 17. In use, by holding the handle 18 and making a circular motion, the rotating plate 17 can be rotated, thereby driving the threaded post 2 to rotate.

[0027] The lifting plate 3 is a plate body with a certain thickness and length, which is threadedly connected with the threaded column 2. The lifting plate 3 is provided with a threaded hole 30 at the end, and the lifting plate 3 is threadedly connected with the threaded column 2 through the threaded hole 30, so that the rotating movement of the threaded column 2 can be converted into the lifting movement of the lifting plate 3 without synchronously rotating with the threaded column 2. Therefore, a limiting rod 11 is needed, which is vertically connected to the bottom plate 1 and passes through the lifting plate 3, and is used to limit the synchronous rotation of the lifting plate 3 with the threaded column 2.

[0028] Further combined Figure 2 And Figure 3 A limiting hole 12 is formed in the lifting plate 3, and an arc-shaped slot 13 is formed in the bottom plate 1 and surrounds the bearing hole 9, and the arc of the arc-shaped slot 13 is a semicircle. A connecting plate 10 is rotatably connected to the upper end of the threaded column 2 through a bearing. The limiting rod 11 passes through the limiting hole 12 in the lifting plate 3, and the lower end of the limiting rod 11 is inserted into the arc-shaped slot 13, and the upper end of the limiting rod 11 is connected with the connecting plate 10. In this way, the lifting plate 3 is limited to rotate and can only be lifted up and down along the limiting rod 11.

[0029] A sliding slot 14 is formed in the inner wall of the arc-shaped slot 13 along the length and width direction of the bottom plate 1, and a limiting ring 15 is fixedly sleeved at the lower end of the limiting rod 11, which is slidably inserted into the sliding slot 14, so that the limiting rod 11 can move along the track of the arc-shaped slot 13. While the lower end of the limiting rod 11 moves, the connecting plate 10 can synchronously rotate to drive the upper end of the limiting rod 11 to move, so that the limiting rod 11 always maintains a vertical state with the bottom plate 1. While the limiting rod 11 moves, the lifting plate 3 rotates, and the direction of the lifting plate 3 is adjusted.

[0030] A positioning screw pipe 16 is threadedly connected to the lower part of the limiting rod 11, and the lower end of the positioning screw pipe 16 abuts against the top surface of the bottom plate 1. The positioning screw pipe 16 can play a certain supporting role to reduce the weight of the limiting ring 15. At the same time, the positioning screw pipe 16 can also limit the lifting plate 3 to descend to the lowest end of the limiting rod 11, and play a certain limiting role on the stroke of the lifting plate 3.

[0031] Further combined Figure 4 The rotating plate 4 is rotatably connected above the lifting plate 3, and the rotating plate 4 is mainly used for placing the lower limbs, and has a rotating function to adjust the angle of the lower limbs of the patient, which effectively improves the comfort. A rotating hole 5 is formed in the middle position of the lifting plate 3, and a rotating bolt 6 is rotatably connected in the rotating hole 5. The top of the rotating bolt 6 is fixedly connected with the bottom surface of the rotating plate 4, and the bottom of the rotating bolt 6 is a disc head with a width greater than the rotating hole 5, and the rotating bolt 6 plays a role of a rotating shaft.

[0032] In order to prevent the lower limbs from falling out of the rotating plate 4, a limiting arc plate 8 is fixedly arranged on both sides (length direction) of the top surface of the rotating plate 4. The limiting arc plate 8 is made of soft material.

[0033] In use, the staff can first rotate the threaded column 2, and the rotating threaded column 2 drives the lifting plate 3 to move upward or downward on the threaded column 2 through the threaded connection with the lifting plate 3, so as to adjust the height of the lifting plate 3; then the lower limbs of the patient are placed on the rotating plate 4, and the positions of the lifting plate 3 or the rotating plate 4 are adjusted according to the length of the lower limbs of the patient and the surgical position, so that the application range of lithotomy surgery for different patients is increased.

[0034] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
