[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a pelvic fracture suspension traction device, comprising: a mounting plate 7 and a suspension strap 24 (the pelvic fracture suspension strap 24 is prior art, disclosed in Chinese patent CN221845133 U). A square tube 8 is fixedly mounted on the upper end of the mounting plate 7, and a fixing component is mounted on the lower end of the mounting plate 7. The fixing component includes a fixing plate 1, which is U-shaped. A threaded rod 4 is threadedly connected to the lower end of the fixing plate 1. The upper end of the threaded rod 4 passes through the bottom side wall of the fixing plate 1 and is rotatably connected to a clamping plate 2. One end of the clamping plate 2 is slidably connected to the inner wall of one end of the fixing plate 1. An anti-slip pad 3 is fixedly mounted on the upper end of the clamping plate 2. By fitting the fixing plate 1 onto the bed frame on one side of the hospital bed, and then rotating the threaded rod 4 to drive the clamping plate 2 and the anti-slip pad 3 to move and make close contact with the bottom frame of the hospital bed, the device is fixed to the hospital bed. The device is easy to fix and the fixing position is easy to adjust.
[0023] A column 5 is fixedly installed on the upper side wall of the fixing plate 1. A sleeve 6 is sleeved on the outer end of the column 5 and fixedly connected by bolts. The upper end of the sleeve 6 is fixed to the lower end of the mounting plate 7, which facilitates the disassembly and assembly of the square tube 8 and the screw rod 10.
[0024] A sliding hole 9 is provided at one end of the square tube 8. A lead screw 10 is rotatably connected inside the square tube 8. A threaded sleeve 14 is threaded onto the outer end of the lead screw 10. A slider 15 is fixedly installed at one end of the threaded sleeve 14. The slider 15 is U-shaped. The outer end of the slider 15 slides out of the sliding hole 9 and is connected to a support rod 18 through a rotating component. A first steering gear 11 is fixedly installed at the lower end of the lead screw 10. A crank handle 12 is rotatably connected to the lower end of the square tube 8. One end of the crank handle 12 is inserted into the square tube 8 and a second steering gear 13 is fixedly installed. The outer wall of the second steering gear 13 meshes with the outer wall of the first steering gear 11. By turning the crank handle 12, the second steering gear 13 can be driven to rotate. When the second steering gear 13 rotates, it will drive the first steering gear 11 to rotate with the lead screw 10, thereby driving the threaded sleeve 14 and the slider 15 to move on the outer wall of the lead screw 10.
[0025] The rotating component includes a rotating plate 16 and two limiting holes 19. The rotating plate 16 is fixedly installed at one end of the support rod 18, and the other end of the rotating plate 16 is inserted into the slider 15 and rotatably connected by a round shaft 17. The limiting holes 19 are opened on the side walls of the slider 15 and the rotating plate 16. The two limiting holes 19 are 90 degrees apart with the round shaft 17 as the center. A limiting pin 20 is inserted into one of the limiting holes 19. The support rod 18 can be fixed to the upper middle part of the bed or to the top of the bed frame by the limiting pin 20. Then the fixing plate 1 can be moved to one side of the head of the bed, which does not take up space and is convenient to use.
[0026] Two sliding sleeves 21 are slidably connected to the support rod 18. Each sliding sleeve 21 has a hook 23 fixedly installed at its lower end. The two hooks 23 are hooked to both ends of the suspension strap 24. Each sliding sleeve 21 has a hand-tightening bolt 22 threadedly connected to its upper end. The lower end of the hand-tightening bolt 22 can contact the upper end of the support rod 18, which facilitates the adjustment and fixation of the position of the sliding sleeve 21. The suspension strap 24 wraps around the patient's pelvis.
[0027] When this device is in operation, the fixing plate 1 is sleeved onto the bed frame on one side of the hospital bed. Then, the threaded rod 4 is rotated to drive the clamping plate 2 and the anti-slip pad 3 to move and make tight contact with the bottom frame of the hospital bed, thus fixing them to the hospital bed. The support rod 18 can be fixed to the upper middle part of the hospital bed for use by the limiting pin 20. When not in use, the support rod 18 can also be fixed above the bed frame, and then the fixing plate 1 can be moved to the side of the headboard. It does not take up space, is simple to operate, and is convenient to use.
