Embodiment 1

[0025] Such as figure 1 , 2 shown.

[0026] A retractor for distal radius fracture reduction, which includes two first retractor main rods 5 and second retractor main rods 9 connected by ball joints at one end, and a locking screw 1 is arranged at the ball joints. After the length is adjusted in place, the patient's arm length after reset can be fixed by the locking screw 1, so that the traction is reliable. The other end of the first tractor main rod 5 and the second tractor main rod 9 are all provided with threads, and are respectively connected with driving handwheels 3, 12, and only need to grasp the position elbow rest 7 or 12 with one hand during use. The finger rest struts 6 can keep them from rotating with the main rod of the retractor. Finger rest nuts 4 and elbow rest nuts 10 are respectively installed on the threads, and the finger rest struts 6 are connected to the finger rest nuts 4. 3, 12 The distance between the elbow rest 7 and the finger rest pole 6 can be ...

Embodiment 2

[0037] Such as image 3 shown.

[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 pole 6, fix the five fingers of the affected limb with the finger clamping tractor in sequence, and adjust the position of the finger clamping tractor on the ring-shaped fixing frame until the desired position is reached. Locking studs secure.

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

Abstract

A retractor for distal radius fracture reduction and shoulder joint dislocation, which includes two first retractor main rods (5) and second retractor main rods (9) connected at one end by ball joints, the first retractor main rod (5), the other end of the main rod of the second tractor (9) is provided with threads, and the finger nuts (4) and elbow nuts (10) are respectively installed on the threads, and the finger nuts (4) are connected There is a finger support pole (6), and a fixed frame (11) is installed on the upper end of the finger support pole (6), and a finger clamp tractor (2) is installed on the fixed frame (11); on the elbow support nut (10) An elbow rest (7) is installed, a wrist rest (8) is movably installed on the first retractor main rod (5) or the second retractor main rod (9), and locking screws ( 1). It has the advantages of simple use and operation, good patient compliance and tolerance, and can be independently completed by a single person for all fixation and traction work. At the same time, it also has the characteristics of simple production and maintenance, low cost, durable and easy to popularize.

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...
