[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] See also Figure 1 , Figure 2 and Figure 3A postoperative rehabilitation nursing device comprises an I-shaped fixed beam 1 with a bolt hole 2 on the top, a convex slide rail 3 integrally arranged at the bottom of the I-shaped fixed beam 1, two limit slide bars 4 arranged along the length direction of the upper surface of the convex slide rail 3, and two slings 7 for placing the patient's limbs. According to the position of the bed and the position of the patient's injured limb, the I-shaped fixed beam 1 is fixed to the ceiling of the corresponding house by bolts.
[0026] In order to adjust the horizontal position and adjust the horizontal suspension position, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , it is necessary to set up two horizontal sliding adjustment mechanisms 5, which are provided with a rectangular slider body 51 placed on the periphery of the convex slide rail 3 and capable of axially moving along the convex slide rail 3, a limit contact rod 59 located in the middle of the rectangular slider body 51 and capable of abutting against the bottom surface of the convex slide rail 3, and a coil spring 511 that generates an upward elastic force on the limit contact rod 59, so that the rectangular slider body 51 is fixed to the bottom of the convex slide rail 3. When the lateral spacing of the sling 7 needs to be adjusted, the longitudinal push-pull rod 510 is pulled downward, so that the inner movable plate 58 drives the limit contact rod 59 moves downward. When the limit resistance rod 59 is separated from the bottom surface of the convex slide rail 3, a horizontal force can be applied to the rectangular slider body 51 to adjust the lateral spacing of the sling 7. After adjusting to the appropriate position, the downward pressure on the longitudinal push-pull rod 510 is released. Since the initial length of the coil spring 511 is greater than the height of the longitudinal component movable cavity 57, and the friction force formed by the coil spring 511 on the limit resistance rod 59 and the convex slide rail 3 on the resistance surface is sufficient to keep the rectangular slider body 51 stable, the rectangular slider body 51 will be fixed.
[0027] For the specific structure of the horizontal sliding adjustment mechanism 5, please refer to Figure 4 and Figure 5, including a rectangular slider body 51, the interior of the rectangular slider body 51 is provided with a convex slide groove 52 with an open top and sleeved on the periphery of the convex slide rail 3, and the rectangular slider body 51 is provided with a limiting slide groove 53 that is stuck on the surface of the limiting slide bar 4.

The longitudinal hollow outer shell 54 is provided with an inner movable plate 58 capable of axially moving along the longitudinal component active cavity 57 inside the longitudinal component active cavity 57. The upper end surface of the inner movable plate 58 is fixedly installed with a limit abutment rod 59 passing through the upper rod body through-hole 55. In order to have a sufficient movement stroke, it is necessary to make the length of the limit abutment rod 59 greater than the depth of the upper rod body through-hole 55.

When the longitudinal threaded sleeve 61 is rotated, the lower threaded structure 64 includes an internal threaded structure arranged on the circumferential surface of the lower threaded hole 62 and an internal threaded structure arranged on the circumferential surface of the lower threaded hole 62. The external thread structure on the rod body of the lower longitudinal threaded rod 66, the upper thread structure 65 includes an internal thread structure arranged on the circumferential surface of the upper threaded hole 63 and an external thread structure arranged on the rod body of the upper longitudinal threaded rod 67, and the spiral direction of the lower thread structure 64 is opposite to the spiral direction of the upper thread structure 65. When the longitudinal threaded sleeve 61 rotates, according to the characteristics of the thread force, the lower longitudinal threaded rod 66 and the upper longitudinal threaded rod 67 will be subjected to axial forces in different directions, which will cause the lower longitudinal threaded rod 66 and the upper longitudinal threaded rod 67 to move away from or approach each other, thereby changing the height of the sling 7.
[0029] For the specific structure of the threaded height adjustment mechanism 6, please refer to Figure 6 and Figure 7, including a longitudinal threaded sleeve 61, the lower half of the longitudinal threaded sleeve 61 is provided with a lower threaded hole 62 with an open bottom end, the upper half of the longitudinal threaded sleeve 61 is provided with an upper threaded hole 63 with an open top end, the longitudinal threaded sleeve 61 is provided with a lower longitudinal threaded rod 66 installed in the lower threaded hole 62 through a lower threaded structure 64, and the longitudinal threaded sleeve 61 is provided with an upper longitudinal threaded rod 67 in the upper threaded hole 63 through an upper threaded structure 65. Specifically, the lower threaded structure 64 includes an internal threaded structure arranged on the circumferential surface of the lower threaded hole 62 and an external threaded structure arranged on the rod body of the lower longitudinal threaded rod 66, the upper threaded structure 65 includes an internal threaded structure arranged on the circumferential surface of the upper threaded hole 63 and an external threaded structure arranged on the rod body of the upper longitudinal threaded rod 67, and the spiral direction of the lower threaded structure 64 is opposite to that of the upper threaded structure 65, and a polygonal A limiting rod 611, and the lower longitudinal threaded rod 66 and the upper longitudinal threaded rod 67 are both provided with polygonal limiting holes 610 for placing the polygonal limiting rod 611 on the opposite end faces. In order to prevent the components from rotating, it is necessary to make the structural shape of the cross-section of the polygonal limiting hole 610 consistent with the structural shape of the cross-section of the polygonal limiting rod 611, both of which are polygonal structures, and the structural dimensions of the cross-section of the polygonal limiting hole 610 match the structural dimensions of the cross-section of the polygonal limiting rod 611. A polygonal anti-slip protrusion structure 612 of an integrated structure is provided in the middle of the outer circumferential surface of the longitudinal threaded sleeve 61. A lower fixed connecting plate 68 is installed at the bottom end of the lower longitudinal threaded rod 66, and an upper fixed plate 69 is installed at the top end of the upper longitudinal threaded rod 67, and the upper fixed plate 69 is fixedly installed at the bottom of the lower fixed plate 513. The bottom of the lower fixed connecting plate 68 is provided with two belt body embedding grooves 613 for fixing the belt body structure of the port of the sling 7.
[0030] When in use, according to the position of the bed and the position of the patient's injured limb, the I-shaped fixed beam 1 is fixedly installed on the ceiling of the corresponding house by bolts, and the longitudinal push-pull rod 510 is pulled downward, so that the inner movable plate 58 drives the limit contact rod 59 to move downward. When the limit contact rod 59 is separated from the bottom surface of the convex slide rail 3, a transverse force can be applied to the rectangular slider body 51 to achieve the lateral spacing adjustment of the sling 7. After adjusting to the appropriate position, the downward pressure on the longitudinal push-pull rod 510 is released, so that the rectangular slider body 51 is fixed, and the longitudinal threaded sleeve 61 is rotated. According to the characteristics of the thread force, the lower longitudinal threaded rod 66 and the upper longitudinal threaded rod 67 will be subjected to axial forces in different directions, which will cause the lower longitudinal threaded rod 66 and the upper longitudinal threaded rod 67 to move away from or approach each other, thereby changing the height of the sling 7. After the position adjustment of the sling 7 is completed, the patient's limb can be raised and limited according to the limb lifting procedure.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
