Abstract

The invention provides a fixation device for rehabilitation of fractures of the patella inferior pole. The fixation device for rehabilitation of the fractures of the patella inferior pole comprises afirst perforation, a fixing plate and a second perforation which are connected sequentially, wherein a strip-shaped structure passes through the first perforation and the second perforation, the strip-shaped structure is used for fixing the fixation device to the fracture positions of the patella inferior pole and connecting the patella inferior pole with the patella main body tightly and closely,and a closed ring can be formed by the strip-shaped structure; and the fixing plate can be used for connecting the fractured patella inferior pole with the patella main body fixedly so as to achievethe purpose of fracture healing. Through the fixation device, the fractured block of the patella main body and the fractured block of the patella inferior pole of a patient can be in close contact, pressurized fixation is achieved, subsequent fracture rehabilitation can be accelerated, frequent operation and damage to the patella inferior pole of the patient can be reduced greatly, risks of postoperative complications can be reduced effectively, and the speed of rehabilitation can be improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a rehabilitation and fixation device for fractures of the lower pole of the patella. Background technique [0002] Patella fractures are clinically common intra-articular fractures, including fractures of the main part of the patella and fractures of the lower pole of the patella. For patients with fractures of the lower pole of the patella, open reduction and internal fixation is used clinically for fracture treatment. [0003] After a massive search by the applicant, it was found that the treatment plan for the lower pole of the patella in the prior art, such as the internal fixation device for the lower pole of the patella disclosed by the publication number CN208784891U, includes a fixing titanium cable, a first fixing washer, a first fixing screw, The second fixed washer piece and the second fixed screw; the first fixed washer piece and the second fixed washer piece are cor...
