[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] like Figure 1 , 7As shown, the tilting mechanism 4 includes a threaded seat 401, a tilting rack 402, a tilting motor 403, a threaded column 404, a tilting seat 405, a tilting gear 406, a tilting column 407, a leg support 408, a bottom plate 409, a lifting rod 410303, and a limiting sleeve 411; a slide groove is arranged at the front end of the lifting rod 410303, a rack is arranged on one side of the slide groove, a tilting seat 405 is symmetrically arranged at the front end of the lifting rod 410303, and a threaded seat 401 is arranged on the end face of the lifting rod 410303; the threaded seat 401 A tilting motor 403 is arranged at the front end; a threaded column 404 is arranged on the output shaft of the tilting motor 403 and is threadedly connected to a threaded seat 401; the front end of the threaded column 404 is movably connected to a tilting rack 402; the two tilting seats 405 are rotatably connected to a tilting column 407, and a limiting sleeve 411 is arranged on one end of the tilting seat 405 and is movably connected to the tilting rack 402; a tilting gear 406 is arranged on the tilting column 407 to mesh with the tilting rack 402, a leg support 408 is arranged above the tilting column 407, and a bottom plate 409 is arranged at the front end of the leg support 408;

[0034] In this embodiment, the working principle of the tilt mechanism 4 is as follows: the threaded column 404 is driven to rotate by the rotation of the tilt motor 403, and the threaded column 404 is threadedly connected with the threaded seat 401 to rotate and extend along the threaded seat 401, thereby pushing the tilt rack 402 to extend and retract along the tilt gear 406, and through the limitation of the threaded seat 401 and the limiting sleeve 411, the tilt rack 402 pushes the tilt gear 406 to rotate, thereby driving the tilt column 407 to rotate along the tilt seat 405, thereby driving the leg rest 408 to tilt, thereby achieving the purpose of adjusting the angle of the leg rest 408, solving the problem that the leg rest 408 part can only adjust the front and rear position in the existing device in the prior art, but cannot achieve the tilting effect;

[0035] In this embodiment, the leg support device in the prior art often only allows adjustment of the front and rear position, but cannot adjust the tilt angle. The tilt mechanism 4 of the present invention can adjust the tilt angle of the leg rest 408 through the coordinated work of components such as the threaded seat 401, the tilt rack 402, the tilt motor 403, the threaded column 404, the tilt seat 405, the tilt gear 406, and the tilt column 407, so as to better adapt to different surgical needs and patient positions.

[0036] Example 2

[0037] like Figure 2 , 3As shown in , 5 and 6, the telescopic device 2 includes a telescopic screw 201, a telescopic seat 202, a telescopic column 203, a telescopic shell column 204, a telescopic gear 205, a telescopic pull rod 206, a telescopic clamping column 207, a limiting column 208, and a limiting shell 209; the telescopic seat 202 is movably connected to the bed body 1, and cylindrical telescopic shell columns 204 are symmetrically arranged at both ends of the telescopic seat 202; a rectangular limiting shell 209 is arranged at the rear end of the telescopic shell column 204, and the telescopic column 203 is slidably connected inside the telescopic shell column 204; an L-shaped telescopic clamping column 207 is arranged at the front end of the telescopic column 203 to slide and connect The limit shell 209; the telescopic column 207 is provided with a hole in the center thereof for sliding connection with the telescopic pull rod 206; the front end section of the telescopic column 207 is provided with a square hole, and a telescopic gear 205 is provided in the middle of the square hole; the telescopic screws 201 are symmetrically provided at both ends of the telescopic gear 205; the front end of the telescopic screw 201 is threadedly connected to the telescopic column 207 and passes through the square hole; a rack is provided on the telescopic pull rod 206 to mesh with the telescopic gear 205; the limit shell 209 is provided with a plurality of penetrating square holes in the horizontal direction and a penetrating square hole in the vertical direction; the telescopic screws 201 at both ends have opposite rotation directions and the same pitch;

[0038] In this embodiment, the working principle of the telescopic device 2 is as follows: by pulling the telescopic pull rod 206 to slide along the hole in the telescopic seat 202, the telescopic gear 205 meshing therewith is driven to rotate, the rotation of the telescopic gear 205 drives the telescopic screw 201 to rotate, and the rotation of the telescopic screw 201 drives the telescopic clamping column 207 to slide along the telescopic seat 202 through a threaded connection, so that it disengages from or is stuck in the square hole in the horizontal direction of the limit shell 209, thereby limiting the device in the axial and circumferential directions;

[0039] In this embodiment, when the device needs to be stored, the telescopic rod is pulled to make the limiting clamping column disengage from the limiting square hole, and the device is pulled to make the limiting column 208 disengage from the fiber shell, and the device can be rotated 90 degrees, the telescopic column 203 is pushed to the bottom, and the telescopic pull rod 206 is pushed to make the telescopic clamping column 207 clamped into the square hole in the vertical direction of the limiting shell 209;

[0040] In this embodiment, the limiting shell 209 is provided with a plurality of penetrating square holes in the horizontal direction, and when the device is used, the gap between the left and right devices can be adjusted to a suitable position according to the needs of the patient and the operation;

[0044] In this embodiment, the working principle of the lifting mechanism 3 is as follows: by rotating the lifting rocker 301, the lifting gears 302 on the left and right sides are driven to rotate, and the lifting gears 302 are meshed with the racks at the bottom of the lifting rod 410303. Since the lifting gear 302 is limited by the lifting rocker 301 so that it can only rotate on its own, the rotation of the lifting gear 302 will push the lifting rod 410303 to slide up and down, thereby achieving the purpose of adjusting the height of the device;

[0045] In this embodiment, the lifting rocker 301 penetrates the lifting mechanism 3 connecting the left and right ends, and the two devices can be lifted and adjusted at one time when adjustment is needed, thereby improving work efficiency;

[0046] In this embodiment, the lifting mechanism 3 allows medical staff to accurately adjust the height of the leg support according to surgical needs and the patient's body position through the cooperation of the lifting rocker 301 and the lifting gear 302. The design of the lifting mechanism 3 makes the height adjustment quick and convenient, thereby improving surgical efficiency.

[0047] In summary, the present invention provides a telescopic column 203 and a limiting column 208 that can slide and rotate in the telescopic shell column 204 and the limiting shell 209, and pulls the telescopic pull rod 206 to slide, so that the telescopic gear 205 meshing therewith rotates, so that the telescopic gear 205 drives the telescopic screw rods 201 at both ends to rotate, so that the telescopic clamping columns 207 at both ends are retracted into the limiting column 208 through threaded connection, and the limiting column 208 is pulled to separate from the limiting shell 209 to rotate the device by 90°, so that the device can be stored in the storage table 101;

[0048] At the same time, a tilting mechanism 4 is provided under the leg rest 408, and the threaded column 404 is driven to rotate by the rotation of the tilting motor 403, and the threaded column 404 pushes the tilting rack 402 forward through the threaded connection; thereby, the tilting rack 402 is engaged through the tilting gear 406, so that the tilting rack 402 pushes the tilting gear 406 to rotate, thereby causing the tilting column 407 to rotate along the tilting seat 405, thereby achieving the purpose of adjusting the angle of the leg rest 408.
