Embodiment 1

[0025] As shown in Figure 1 and 2.

[0026] A retractor for distal radius fracture reduction, which includes two retractor main rods 5 and 9 connected at one end by a ball joint, and a locking screw 1 is provided at the bead joint, which can be passed through after the length is adjusted in place. The locking screw 1 fixes the patient's arm length after reset, so that the traction is reliable. The other end of tractor main rod 5,9 is all provided with screw thread, and is connected with driving hand wheel 3,12 respectively, only needs to grasp position elbow rest 7 or finger rest pole 6 with one hand during use so that they do not follow The main rod of the tractor can be rotated, and the finger rest nut 4 and the elbow rest nut 10 are respectively installed on the thread, and the finger rest support rod 6 is connected to the finger rest nut 4, and the elbow rest 7 can be adjusted by shaking the handwheels 3 and 12 respectively. The distance between the finger rest pole 6 is ...

Embodiment 2

[0037] As shown in Figure 3.

[0038] A shoulder joint dislocation retractor, which is composed of a fixed frame 11, a finger clamping retractor 2 that is movably installed and positioned on the fixed frame 11, and a counterweight 15, the counterweight 15 or a cable passing through a pulley 13 14 links to each other with fixed frame 11, or directly links to each other with fixed frame 11 through drag cable 14.

[0039] Shoulder joint dislocation traction process of the present invention is:

[0040] The patient was placed supine with the affected limb slightly abducted. Remove the ring-shaped fixing frame 11 from the finger rest support rod 6, fix the five fingers of the affected limb with the finger clamping tractor in turn, adjust the position of the finger clamping tractor on the ring-shaped fixing frame, and then press Locking studs secure.

[0041] Use a rope to tie a suspension weight of appropriate weight to the ring-shaped fixed frame for continuous suspension tract...

Abstract

The invention discloses a tractor of far-end fracture radius and shoulder joint, which contains main tractor rods (5, 9) with one end hinging by two threads through ball, wherein the screw is set on the other end of main tractor rods (5, 9); the finger-tray nut (4) and elbow-tray nut (10) are assembled on the screw; the finger-tray rod (6) is connected on the finger-tray nut (4); the fixing rack (11) is set on the upper end of finger-tray rod (6), which contains finger clamping tractor (2); the elbow tray (7) is set on the elbow-tray nut (10); the wrist tray (8) is set on the main tractor rod (5) or main tractor rod (9) without fixing; the locking screw pin (1) is loaded on each mobile connecting position.

Description

technical field [0001] The invention relates to a medical device, especially a manual and adjustable retractor suitable for orthopedic clinical use for forearm distal radius fractures and shoulder joint dislocations, specifically a traction device for the reduction of distal radius fractures and shoulder joint dislocations device. Background technique [0002] At present, with the changes of the times and society, the spectrum of orthopedic injuries has undergone great changes. Bone and joint tuberculosis, suppurative infection, polio, etc. have been greatly reduced in the past, and trauma in traffic accidents has increased significantly. At the same time, with the aging of the global population, the fractures caused by senile osteoporosis also increase accordingly. [0003] Colles fractures, Smith fractures, and double fractures of the distal ulna and radius are among the most common fractures in the human body. They mostly occur in middle-aged and elderly people, and mor...
