Description
Technical Field
The invention relates to the field of closed reduction or incision reduction operation and temporary fixation operation of calcaneus in calcaneus fracture operation, in particular to a closed reduction device of the calcaneus.
Background
In clinical operation, a plurality of assistants are usually required to complete plantar flexion of feet, hand-held traction of cloth forceps and pushing of a top rod are combined together, so that manpower is increased, the operation devices and the technology are assembled into a device, the calcaneus fracture reduction efficiency is improved, the reduction accuracy is improved, and particularly in closed fracture reduction, after the fracture reduction is completed, the assistants are required to be exposed under X rays for carrying out the closed reduction operation of the fracture; the prior reduction device has certain defects when in use, and the prior calcaneus fracture reduction device only comprises a part of reduction devices for calcaneus fracture and cannot comprehensively recover the height and the width of the calcaneus and correct the calcaneus eversion or varus deformity andthe angle can not meet the use requirement of people, brings certain influence to the use process of people,to this end, we propose a closed reduction device for the calcaneus.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a calcaneus fracture reduction device.
In order to solve the technical problems, the invention provides the following technical scheme:
the invention relates to a calcaneus fracture reduction device which comprises plantar flexion, wherein a support frame is fixedly arranged on the outer surface of the bottom end of the plantar flexion, a top rod is fixedly arranged on one side of the outer surface of the support frame, a Style needle is fixedly arranged on the other side of the outer surface of the support frame, and a towel clamp is fixedly arranged on the outer surface of the upper end of the support frame.
Preferably, finger rings are fixedly arranged on two sides of the outer surface of the towel forceps, the shape of each finger ring is elliptical, and the specifications and the sizes of the two groups of finger rings are the same.
Preferably, the inner surface of the towel forceps is provided with movable screws, nuts are fixedly arranged at two ends of the outer surface of each movable screw, the movable screws are located at the center of the nuts, and the number of the nuts is two.
Preferably, a thread wire is arranged at the tip part of the Style needle.
Preferably, the shape of the supporting frame is cylindrical.
The beneficial effects achieved by the invention are as follows: this closed resetting means of calcaneus is in the same place multiple calcaneus restorer is effectual to be combined together, not only effectually reduced the operation of assistant, reduces the assistant X line exposure degree in the closed operation of restoring to the throne of calcaneus moreover, has accomplished accurate reduction simultaneously, can temporarily fix the fracture after the calcaneus resets, and whole device simple structure, convenient operation, the effect of use is better for traditional mode.
Drawings
The accompanying drawings are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate the invention and together with the embodiments of the invention, serve to explain the invention. In the drawings:
