Description

Patella puncture guider

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a patella puncture guide.

Background

The fracture of the patella is one of the more common fractures in clinic, which accounts for about 1.65% of the fracture injury of the whole body, and the patella has important significance in the aspects of the physiological functions of the knee joint, such as stability, movement and the like. After the patella is fractured, the physiological function is lost, so that the functions of the patellofemoral joint and the knee extension of the affected knee are affected, and the life quality of the patient is obviously reduced. The incision reduction tension band fixation is the most accepted and widely applied treatment method by the majority of clinicians, although the tension band is required to be used for fixing simple fracture in AO idea, the tension band can also be suitably applied to comminuted fracture with stable bone cortex behind the patella, comminuted fracture and patellar lower-pole fracture which are assisted by other internal fixation materials to be fixed firstly, and particularly domestic doctors and scholars have more hearts on the application of the tension band.

When the kirschner wire is fixed after the reduction of the existing patella fracture, blind puncture usually needs repeated puncture to achieve an ideal fixed position, sometimes the kirschner wire can enter a joint if the position is not good, and the repeated puncture prolongs the operation time, so the utility model provides the patella puncture guider.
