[0021] This utility model provides a limb fixation device, including a sub-hook and loop fastener 101, a female hook and loop fastener 102, and an arc-shaped plate 103. The sub-hook and loop fastener 101 is fixedly connected to the arc-shaped plate 103 and is located below the arc-shaped plate 103. The female hook and loop fastener 102 is fixedly connected to the arc-shaped plate 103 and is located below the arc-shaped plate 103.
[0022] It also includes a movable component, which includes a base plate 104, casters 105, a fixed housing 106, a moving component, and a height component. The base plate 104 is disposed below the arc-shaped plate 103. The casters 105 are detachably connected to the base plate 104 and are located below the base plate 104. The fixed housing 106 is fixedly connected to the base plate 104 and is located above the base plate 104. The moving component is disposed inside the fixed housing 106, and the height component is disposed inside the base plate 104.
[0023] In this embodiment, the casters 105 provided below the base plate 104 facilitate the overall movement of the limb fixation device. The fixed housing 106 fixes the moving part and the height part above the base plate 104. By controlling the height part, the moving part and the arc plate 103 can be moved up and down, thereby adjusting the height of the patient's leg. By controlling the moving part, the arc plate 103 can be moved laterally and longitudinally, thereby adjusting the lateral and longitudinal positions of the patient's leg.
[0024] Furthermore, the moving component includes a connecting rod 107, a sliding block 108, a sliding shell 109, and a cylinder 110. The connecting rod 107 is fixedly connected to the arc-shaped plate 103 and is located above the arc-shaped plate 103. The sliding block 108 is fixedly connected to the connecting rod 107 and is located at the end of the connecting rod 107 away from the arc-shaped plate 103. The sliding shell 109 is slidably connected to the sliding block 108 and encloses the sliding block 108. The cylinder 110 is detachably connected to the sliding shell 109 and is located outside the sliding shell 109. The output end of the cylinder 110 is fixedly connected to the sliding block 108.
[0025] In this embodiment, by controlling the cylinder 110, the sliding block 108 can be driven to slide within the sliding shell 109, thereby driving the arc plate 103 to move longitudinally via the connecting rod 107, thus adjusting the longitudinal position of the patient's leg.
[0026] Furthermore, the moving component also includes a moving block 111, a moving screw 112, a fixing plate 113, and a moving motor 114. The moving block 111 is fixedly connected to the sliding shell 109 and is located above the sliding shell 109. The moving screw 112 is threadedly connected to the moving block 111 and passes through the moving block 111. The fixing plate 113 is rotatably connected to the moving screw 112 and is located at one end of the moving screw 112. The output end of the moving motor 114 is fixedly connected to the moving screw 112 and is located at the end of the moving screw 112 away from the fixing plate 113.
[0027] In this embodiment, the fixed motor can drive the moving screw 112 to rotate. The rotation of the moving screw 112 can drive the moving block 111 to move laterally, thereby driving the arc plate 103 below the sliding shell 109 to move laterally, thereby adjusting the lateral position of the patient's leg.
[0028] Furthermore, the height component includes a drive motor 115, a drive screw 116, a guide rod 117, a height plate 118, and a stabilizing unit. The drive motor 115 is detachably connected to the fixed housing 106 and is located above the fixed housing 106. The output end of the drive motor 115 penetrates the top surface of the fixed housing 106. The drive screw 116 is fixedly connected to the output end of the drive motor 115 and is located inside the fixed housing 106. The guide rod 117 is fixedly connected to the fixed housing 106 and is located inside the fixed housing 106. The height plate 118 is threadedly connected to the drive screw 116 and wraps around the drive screw 116 and the guide rod 117. The height plate 118 is fixedly connected to the fixed plate 113. The stabilizing unit is disposed on the outside of the base plate 104.
[0029] In this embodiment, the drive motor 115 drives the drive screw 116 to rotate, which, with the assistance of the guide rod 117, drives the height plate 118 to move up and down, thereby driving the arc plate 103 to move up and down, thus adjusting the height of the patient's legs.
[0030] Furthermore, the stabilizing unit includes a placement plate 119, a threaded rod 120, and a pressure block 121. The placement plate 119 is fixedly connected to the base plate 104 and is located outside the base plate 104. The threaded rod 120 is threadedly connected to the placement plate 119 and passes through the placement plate 119. The pressure block 121 is fixedly connected to the threaded rod 120 and is located below the threaded rod 120.
[0031] In this embodiment, rotating the threaded rod 120, with the assistance of the placement plate 119, will cause the pressure block 121 to move up and down. When the threaded rod 120 presses down on the pressure block 121, the pressure block 121 contacts the ground, increasing the friction of the limb fixation device as a whole, thereby increasing the overall stability of the device.
[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
