Problems solved by technology

[0004] In view of this, the purpose of the present invention is to address the deficiencies of the prior art, and to provide a leg fracture reduction device for orthopedics, which adopts the circumferential pre-fixation above the fracture site, and pulls through the traction mechanism, and finally performs progressive Pushing the top to reset avoids the problem that the pulling force cannot be controlled in the prior art, effectively reduces the medical risk during the reset process, and improves the controllability during the treatment process. At the same time, it is equipped with a support mechanism to avoid partial support from causing damage to the patient's body. The phenomenon that the device fails due to shaking

Embodiment 1

[0037] Such as figure 1 , 6 As shown in -8, the present invention includes a columnar support mechanism, a traction mechanism that cooperates with the columnar support mechanism, and a leg support mechanism that cooperates with the columnar support mechanism and the traction mechanism,

[0038] The column support mechanism includes two arc-shaped frames, the right ends of the two arc-shaped frames are connected by hinges, and the left ends are fixed by bolts 1. The arc-shaped frames include two supporting plates 2 and four A first arc-shaped plate 3, the first arc-shaped plate 3 is provided with three first threaded through holes along the circumference, the first threaded through hole is internally threaded to connect the first screw 4, and one end of the first screw 4 is connected to the second arc. Plate 5, the second arc-shaped plate 5 is located in the columnar support mechanism, and the lower end of the columnar support mechanism is provided with two through holes, the ...

Embodiment 2

[0044] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as figure 2 As shown, the inner end surface of the second arc-shaped plate 5 is provided with a protective mechanism, and the protective mechanism successively includes a rubber layer 10, an airbag layer 11 and a non-woven fabric layer 12 bonded and fixed, and the rubber layer 10 is fixedly connected with the second arc-shaped plate 5 .

Embodiment 3

[0046] Such as image 3 Shown, the present invention comprises column support mechanism, traction mechanism and positioning mechanism:

[0047] The column support mechanism includes two arc-shaped frames, the right ends of the two arc-shaped frames are connected by hinges, and the left ends are fixed by bolts 1. The arc-shaped frames include two supporting plates 2 and four A first arc-shaped plate 3, the first arc-shaped plate 3 is provided with three first threaded through holes along the circumference, the first threaded through hole is internally threaded to connect the first screw 4, and one end of the first screw 4 is connected to the second arc. Plate 5, the second arc-shaped plate 5 is located in the columnar support mechanism, and the lower end of the columnar support mechanism is provided with two through holes, the first arc-shaped plate 2 and the second arc-shaped plate 5 are made of transparent resin materials;

[0048] The traction mechanism includes a pedal 6 a...

Abstract

The invention belongs to the technical field of orthopedic medical equipment, and particularly relates to a leg fracture reduction device for an orthopedics department. The leg fracture reduction device for the orthopedics department comprises a columnar supporting mechanism, a traction mechanism and a leg supporting mechanism, wherein the traction mechanism is matched with the columnar supportingmechanism; and the leg supporting mechanism is matched with the columnar supporting mechanism and the traction mechanism during supporting. The upper part of a fracture part is pre-fixed in the peripheral direction, dragging is carried out by the traction mechanism, finally, gradual pushing reduction is carried out, the problem that the traction force cannot be controlled in the prior art is avoided, medical risks in a reduction process are reduced effectively, and controllability in a treatment process is improved. Meanwhile, by the supporting mechanism, the circumstance that the body of a patient shakes due to local supporting to cause failing of the device is avoided.

Description

technical field [0001] The invention belongs to the technical field of orthopedic medical equipment, in particular to a leg fracture reduction device for orthopedics. Background technique [0002] In the treatment of fracture reduction in orthopedic surgery, the current reduction of the fracture site is first required. After the reduction is satisfactory, internal fixation or external fixation is used for fixation. The effect of reduction will directly affect the rehabilitation effect of the patient in the later stage. The commonly used reduction method in China Generally, there are two types: one is open reduction, the operation process of this method is relatively simple and easy to operate, but for patients, there are large trauma, heavy bleeding, easy infection, high requirements on the skin, and easy fracture nonunion after periosteum damage The second is closed reduction, relying on the clinical experience of doctors, and using X-ray fluoroscopy to assist in confirming...
