External fixation support for orthopedics department

Abstract

The invention discloses an external fixation support for orthopedics department, and relates to the technical field of medical instruments. The external fixation support comprises connecting rings, adjusting mechanisms and kirschner wires, wherein the two connecting rings are arranged between the two adjusting mechanisms; the adjusting mechanisms comprise extension rod mechanisms, side adjusting mechanisms and rotary rapid adjusting mechanisms; two side adjusting mechanisms are arranged at the two ends of each extension rod mechanism, and each two side adjusting mechanisms are connected through one kirschner wire; and one end of each extension rod mechanism is provided with one rotary rapid adjusting mechanism, the side adjusting mechanism located at one end of each extension rod mechanism is connected with the corresponding rotary rapid adjusting mechanism, and each rotary rapid adjusting mechanism is connected with one end of one corresponding connecting ring. According to the support, bones at the two ends of a fracture position can be restored and aligned, the bones can rotate, the angles of the bones can be adjusted, and therefore bone malformation can be corrected; and then the external fixation support for orthopedics department has relatively high stability, is convenient to operate, and can be rapidly operated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an external fixation bracket for orthopedics. Background technique [0002] In traditional external fixation, a splint or plaster is usually used to fix the fracture outside the skin. Since the splint or plaster is separated from the fracture by soft tissues such as muscles, blood vessels, and nerves, there is room for movement at the fracture end, so it is difficult to achieve anatomical alignment. The subsidence of swelling caused by trauma and the disuse of muscle atrophy caused by the inability of the affected limb to move effectively exacerbate the loosening of external fixation, thus easily causing serious consequences such as malunion, delayed union or nonunion of fractures. [0003] The traditional annular external fixator can fix, extend, and migrate bones well, and can easily correct angulation and malalignment deformities. However, the traditional annular exter...

[0002] In traditional external fixation, a splint or plaster is usually used to fix the fracture outside the skin. Since the splint or plaster is separated from the fracture by soft tissues such as muscles, blood vessels, and nerves, there is room for movement at the fracture end, so it is difficult to achieve anatomical alignment. The subsidence of swelling caused by trauma and the disuse of muscle atrophy caused by the inability of the affected limb to move effectively exacerbates the loosening of external fixation, which easily causes serious consequences of malunion, delayed union or nonunion of fractures

[0003] The traditional annular external fixator can fix, extend, and migrate bones well, and can easily correct angulation and malalignment deformities. However, the traditional annular external fixator is very cumbersome to correct rotational deformities. The operation steps More cumbersome, unable to achieve fast operation
