Only one person can complete the treatment of the entire plaster bracket orthopedic fixation, and the orthopedic bed has the advantages of small size, accurate positioning, simple operation, convenient disassembly and installation, easy to carry, low production cost, and has great clinical value. Promote.

In order to maintain the stability of the femoral head, two U-shaped pads 6 that can support the thigh roots that are separated to both sides are provided on the supporting plate in front of the external expansion and supporting mechanism of the legs, which can raise the buttocks, thereby Together with the support mechanism 2 which expands outwards of the legs, the stability of the whole device is improved. The U-shaped cushions 6 are detachably connected to the supporting plate 1 through the cushion base, and can be flexibly selected and installed according to the needs of use.

Wherein, the top of the lifting bracket 3 is provided with a detachable mounting base 31, and the strut 4 includes a left strut 41 protruding from the mounting base 31 to the left and a right strut 42 protruding to the right. , the mounting seat 31 is provided with an adjusting mechanism that can adjust the length of the left and right struts 41 and 42 extending to the left and right sides, and the struts 4 can be adjusted to the required length by the adjusting mechanism. Referring to Fig. 3, the mounting base 31 is provided with a left and right long guide groove 32, and the adjustment mechanism includes a drive shaft 43 disposed on the mounting base 31 and a hand wheel 44 disposed at the outer end of the drive shaft 43, so that One end of the drive shaft 43 stretches into the guide groove 32, and is keyed to the gear 45 in the guide groove 32. There is a left rack gap between the gear 45 and one side of the guide groove 32, and the gear 45 and the guide groove There is a right rack gap between the groove walls on the other side of 32, and the left strut 41 is inserted in the guide groove 32, and one end of the left strut 41 in the guide groove 32 is provided with a rack embedded in the left rack gap. And the left side rack 46 that meshes with gear 45, one end of right strut 42 in guide groove 32 is provided with the right side rack 47 that is embedded in the right rack gap and meshes with gear 45. When adjusting, turn the hand wheel 44, the torsional force is transmitted to the gear 45 through the drive shaft 43, and the upper and lower sides of the gear 45 are respectively meshed with the left rack 46 and the right rack 47, thereby connecting the left strut 41 and the right strut 42 are retracted or protruded synchronously along the guide groove 32. The above-mentioned structure is driven by the gear 45, which can accurately control the protruding length of the strut 4 and ensure the symmetry of the left and right sides.

In addition, the pallet 1 is provided with a groove 11, and the lifting bracket 3 includes a bracket 34 hinged in the groove 11 through a pin shaft 33 and a limiting mechanism that can control the rotation angle of the bracket 34 around the pin shaft, The bracket 34 can be rotated around the pin shaft 33 to prop up the pallet 1 or receive it into the groove 11, so as to be convenient to carry. Referring to FIG. 2 , the limiting mechanism includes a hinge seat 35 arranged at one end of the groove 11 , a caliper 36 hinged on the bracket 34 , and a limiting column arranged on the bracket 34 to limit the maximum swing angle of the caliper 36 37 , the hinged seat 35 has an arc-shaped edge, and the edge of the hinged seat 35 is provided with a ratchet 38 that can cooperate with the caliper 36 . The caliper 36 includes a tip that can cooperate with the ratchet 38 and a tail that extends to one side of the bracket 34 . A reset member 39 is stretched between the caliper 36 and the bracket 34 to make the caliper 36 abut against the limiting post 37 . The working principle of the lifting bracket 3 is to control the lifting of the bracket 34 by adjusting the rotation angle of the bracket 34 around the pin shaft 33, that is, when the bracket 34 rotates upward around the pin shaft 33 (0°-90°), the higher the bracket, the higher the bracket. When the bracket 34 is lifted upwards, the tip of the caliper 36 passes through the ratchet 38. After the bracket 34 is released, the caliper 36 blocks the position of the specific ratchet 38, and the locking is completed under the action of gravity.
