Embodiment 2

[0050] The difference between embodiment two and embodiment one is: as image 3 As shown, the slide plate 1 is provided with a quick fixing mechanism, and the quick fixing mechanism includes a collar 22 fixedly connected to the slide plate 1 by screws. The arch-shaped axes are arranged in parallel. The inner side wall of the collar 22 and the arched inner side wall of the movable plate 5 are bonded with an air bag 23 arranged along the axial direction of the collar 22. Air pump 24, in the present embodiment, the air pump 24 adopts the air pump 24 equipped with the anti-decubitus air mattress bed of Yuwell brand, and the air pump 24 can alternately inflate and discharge adjacent air bags 23 in the collar 22 Gas, also can control the inflation and exhaust of air bag 23 on movable plate 5 simultaneously.

[0051] The specific implementation is as follows:

[0052] In step 1 in the first embodiment, before using the first steel needle 3 to fix the posterior end of the humerus, ...

Abstract

The invention relates to the technical field of auxiliary devices for bone fracture treatment and particularly discloses a humerus stretching and compressing apparatus. The humerus stretching and compressing apparatus comprises a fixed support and a movable support connected to the fixed support in a sliding manner, wherein a fixed rod is detachably connected with the fixed support, a movable rodmovably connected with the fixed rod is connected with the movable support, a first fixing part for fixing a humerus is arranged on the fixed support, a second fixing part for fixing the humerus is arranged on the movable support, and a fracture position of the humerus is located between the first fixing part and the second fixing part; and a rotating mechanism for rotating the humerus is arrangedon the movable support. According to the humerus stretching and compressing apparatus, rapid restoration of the humerus in an axial direction is achieved by using the fixed support and the movable support which are in sliding connection, the rotating mechanism is used for carrying out rapid restoration on angular offset of the humerus, and thus, the problem in the prior art that the humerus cannot be rapidly and accurately restored to an anatomic relationship is solved.

Description

technical field [0001] The invention relates to the technical field of fracture treatment equipment, in particular to a humerus stretching and compressing device. Background technique [0002] Fracture refers to the complete or partial rupture of the continuity of bone structure, which is more common in children and the elderly, and sometimes occurs in young and middle-aged people. The typical manifestations of fracture patients are local deformation after injury, abnormal movement of limbs, and bone friction sound can be heard when moving limbs. In addition, severe wound pain, local swelling, congestion, and movement disorders after injury. Among all fractures, humerus fracture is a kind of shoulder fracture, which occurs frequently, accounting for about 4% to 5% of all fractures in the whole body. The ultimate goal of fracture treatment is to restore the function of the injured limb to the maximum extent. In fracture treatment, the three basic principles of reduction, fix...
