A tibial plateau fracture reducer

Abstract

The invention discloses a tibial plateau fracture reduction device. The device comprises a rod part composed of an upper part and a lower part, the upper part is of an arc-shaped cylindrical structure, the lower part is of a cylindrical structure, and the lower end of the upper part is connected with the upper end of the lower part; the rod part is of a hollow structure, and a first through hole, a plurality of second through holes and a third through hole which penetrate through the hollow structure are formed in the outer side face of the pointed end; a rod handle is installed at the lower end of the lower part, and a soft shaft is installed in the rod part and the handle; a toothed cam is installed at the end, close to the pointed end, of the soft shaft, the other end of the soft shaft is connected to a rotary device, and the rotary device is installed on the lower end face of the rod handle; an ejector is installed in each second through hole and matched with the toothed cam; a camera device is installed in the first through hole, and an illumination lamp is installed in the third through hole; the rod handle is disposed at the lower end of the lower part, and a first button is installed on the outer side face of the rod handle. The ejectors increase the contact area, and secondary harm caused to articular surface cartilage during improper strength exertion is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to the technical field of a tibial plateau fracture reducer. Background technique [0002] Tibial plateau fractures often have articular surface collapse, and one of the main purposes of surgery is to restore the articular surface to its original height. In the current clinical operation, most physicians use narrow osteotome, periosteum stripper, dissecting scissors or equivalent tools to pry up the collapsed articular surface after opening or splitting the proximal tibia, so as to achieve the smoothing of the articular surface and Implement internal fixation. However, we found that in the process of resetting the collapsed platform, the use of traditional narrow osteotome, periosteum stripper or dissection scissors and other reduction tools requires a large fenestration or splitting of the proximal tibia, which increases the secondary damage; The lack of accuracy of the t...

Problems solved by technology

However, we found that in the process of resetting the collapsed platform, the use of traditional narrow osteotome, periosteum stripper or dissection scissors and other reduction tools requires a large fenestration or splitting of the proximal tibia, which increases the secondary damage; The lack of accuracy of the tool in resetting the collapsed articular surface bone block can easily damage and loosen the uninvolved proximal tibial cancellous bone. In addition, the contact surface of the top of these traditional tools is small, and it is easy to puncture the joint when the force is improper. Facial cartilage, causing secondary damage
