Percutaneous closed reduction patella fracture internal fixing device

Abstract

The invention discloses a percutaneous closed reduction patella fracture internal fixation device comprising a reduction forceps main body, an upper clamping piece, a lower clamping piece, an upper locking structure, a lower locking structure and a positioning piece; the upper clamping piece and the lower clamping piece are both arranged on the reduction forceps main body in a penetrating manner and slide along the length direction of the reduction forceps main body, and the upper clamping piece and the lower clamping piece are symmetrically arranged,; the upper locking structure is arranged between the upper clamping piece and the reduction forceps main body to lock the relative positions of the upper clamping piece and the reduction forceps main body; the lower locking structure is arranged between the lower clamping piece and the reduction forceps main body to lock the relative positions of the lower clamping piece and the reduction forceps main body, a first positioning hole is formed in the a part, corresponding to a positioning piece, of the upper clamping piece, and the positioning piece can be sleeved on the upper clamping piece through the first positioning hole; and the positioning piece is provided with an upper positioning hole used for positioning a kirschner wire, and the lower clamping piece is provided with a lower positioning hole corresponding to the kirschner wire. The percutaneous closed reduction patella fracture internal fixation device has the advantages of effective reduction of incision wounds, small operative trauma and short postoperative rehabilitation time.

Description

technical field [0001] The invention relates to the field of medical surgical appliances, in particular to a percutaneous closed reduction and internal fixation device for patella fractures. Background technique [0002] Patellar fractures are one of the more common limb fractures and often require surgical treatment. The current common method is open reduction and internal fixation with Kirschner wire tension band. The effect is satisfactory, but open reduction is required, and the incision is relatively large. The surgical trauma is large and the postoperative recovery time is long. [0003] Therefore, there is an urgent need for a percutaneous closed reduction and internal fixation device for patellar fractures to overcome the above-mentioned defects. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a percutaneous closed reduction and internal fixation device for patella fractures, which can effectively reduce the incision, small sur...
