Packing and fixing device for patella fracture

Abstract

The invention discloses a packing and fixing device for patella fracture. The packing and fixing device for patella fracture comprises fixing bands, locking buckles, and a guiding device. The fixing bands are flexible structures. The fixing bands are wrapped around the patella under the guidance of the guiding device, and at least one fixing band crosses the fracture crease. Both ends of the fixing band are connected and tightened by the locking buckles. In the invention, fixing bands are used to wrap and fix the patella, so that the fractured patella fragments can be firmly closed together. The stress of each fracture surface is balanced, and the fracture dislocation and crease opening can be avoided. Moreover, the fixing bands and the locking buckles have thin thickness, thereby avoidingtissue protrusion and producing discomfort, so that the healing time of fractures can be shortened. The use of absorbable materials solves the problem of the need for secondary surgery to remove theimplant. The minimally invasive surgery using guide needle traction significantly reduces the difficulty of surgery and saves half of the operation time compared to traditional surgeries.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a packing and fixing device for patella fractures. Background technique [0002] The patella is the largest sesamoid bone in the human body. It is located in front of the lower end of the femur and inside the quadriceps tendon. The function of friction on the cartilage surface of the femoral condyle. Patella fracture is a relatively common injury. Usually, there are many methods of internal fixation for patella fractures, such as Kirschner wire tension fixation, memory alloy patella fixation, etc. The fixation tension is concentrated on the front of the patella, and there is no traction on the back, which is easy As a result, the back crease opens, causing the patella to lose its shape during recovery, and the recovery is slow. At the same time, a large incision is required to place the fixation during the operation, and a second operation is required to remo...

Problems solved by technology

Patella fracture is a relatively common injury. Usually, there are many methods of internal fixation for patella fractures, such as Kirschner wire tension fixation, memory alloy patella fixation, etc. The fixation tension is concentrated on the front of the patella, and there is no traction on the back, which is easy As a result, the back crease opens, causing the patella to lose its shape during recovery, and the recovery is slow. At the same time, a large incision is required to place the fixation during the operation, and a second operation is required to remove the fixation; the contact position between the wire linear fixation belt and the patella Greater pressure per unit area will lead to soft tissue necrosis, liquefaction, absorption, and fibrosis, which will loosen the steel wire of the tension band, and the stimulation of the knotted part will cause discomfort to the patient
