Description

Parallel pressure device for orthopedics department

Technical Field

The utility model relates to a parallel pressure device for orthopedics department belongs to orthopedic surgery apparatus technical field.

Background

Fracture refers to a disease of partial or complete fracture of bone due to trauma or pathology, when treating fracture, the broken end of the displaced bone after fracture is usually restored to normal or close to the original normal position, after fracture reduction, the bone is easy to be displaced again because of its instability, so it should be fixed on the satisfied position by different methods to heal gradually, and the fixing method includes external fixation and internal fixation. The general process of internal fixation orthopedic surgery is as follows: medical radiography, observation of fracture conditions, selection of orthopedic screws and matching tools with appropriate specifications → positioning and pressure reduction of fracture sites → preparation of screw tunnels → repair of upper nails.

The Kirschner wire fixation is a common internal fixation method, usually adopts the Kirschner wire fixation for some unstable fractures, and has better clinical Kirschner wire fixation effect for short bones, irregular bones, adjacent joint fracture fixation and trans-joint fixation; when fixing the kirschner wire, at first need install the one end of kirschner wire on the electric drill, then open the electric drill, squeeze into the skeleton that needs to be fixed with the kirschner wire, the kirschner wire need be squeezed into according to predetermined angle and position accuracy, in operation process, the doctor holds the electric drill in case and takes place the shake, cause the angle and the position of squeezing into inaccurate, at this moment just need extract the kirschner wire, squeeze into again, often need squeeze into many times for an operation, invisibly aggravated vice damage, further destroyed the blood supply, the operation time has been prolonged, and then influenced treatment, angle and position at the process of squeezing into the kirschner wire are difficult to master, so the disposable success rate of kirschner wire fixation operation is lower.

The traditional compression reduction tool only can realize the function of holding and fixing the bone block at the fracture part, can not realize the positioning and the compression action in the parallel direction, can not control the moving direction of the bone block during the reduction, and is easy to cause the condition that the bone surface of the fracture part is not jointed after being locked. The existing parallel pressurizing positioner is complex in structure and complex in use steps, and the practicability of the existing parallel pressurizing positioner needs to be improved.
