Embodiment 1

[0034] Patella fracture is a common trauma in orthopedics. Due to the special shape of the patella, there are various ways of internal fixation. The existing fixation methods for patella inferior pole fractures are not ideal.

[0035] The purpose of this design is to design a new steel plate for the fracture of the lower pole of the patella to achieve firm fixation, allow early exercise, and reduce complications.

[0036] On the whole, the steel plate wraps around the lower pole of the patella and the lateral lower part of the patella in an arc shape. There is a transverse tunnel at the front and rear edges of the steel plate to allow the steel wire to pass through, and the body of the steel plate is porous to allow the steel wire to pass through vertically. During the operation, the transverse tunnel passes through 2 steel wires around the patella to the upper edge of the patella and is knotted and fixed. The small hole in the body of the steel plate and the patella tunnel pa...

Embodiment 2

[0042]This embodiment should be understood as at least including all the features of any one of the foregoing embodiments, and further expanded on the basis of it:

[0043] In this embodiment, the steel plate is arc-shaped to surround the lower pole of the patella and the lateral lower part of the patella. There is a transverse tunnel at the front and rear edges of the steel plate to allow the steel wire to pass through, and the body of the steel plate is porous to allow the steel wire to pass through vertically. During the operation, the transverse tunnel passes through 2 steel wires around the patella to the upper edge of the patella and is knotted and fixed. The small hole in the body of the steel plate and the patella tunnel pass through three steel wires longitudinally for axial fixation. The steel plate and steel wire form an organic whole to form a firm structure for the fracture of the patella. fixed.

Embodiment 3

[0067] This embodiment should be understood as at least including all the features of any one of the foregoing embodiments, and further expanded on the basis of it:

[0068] Patella fracture is a common trauma in orthopedics. Due to the special shape of the patella, there are various ways of internal fixation. The existing fixation methods for patella inferior pole fractures are not ideal.

[0069] The purpose of this design is to design a new steel plate for the fracture of the lower pole of the patella to achieve firm fixation, allow early exercise, and reduce complications.

[0070] The steel plate is arc-shaped and wraps around the lower pole of the patella and the lateral lower part of the patella. There is a transverse tunnel at the front and rear edges of the steel plate to allow the steel wire to pass through, and the body of the steel plate is porous to allow the steel wire to pass through vertically.

Abstract

The invention provides a steel plate device for inferior polar fracture of patella. By the steel plate device, the purposes of firm fixation, early exercise permission and few complications are achieved. A fixing steel plate made of materials such as a steel plate is used for wrapping the inferior pole of the patella and the lower portion of the side of the patella in an arc shape, two transversetunnels are connected to the fixing steel plate to allow wire structures such as steel wires to penetrate through, and the fixing steel plate is of a porous mechanism to allow the steel wires to vertically penetrate through. During an operation, the steel wires penetrate through the two transverse tunnels to surround the patella to the upper edge of the patella to be knotted and fixed, the multiple steel wires longitudinally penetrate through small holes in the fixing steel plate and the patella tunnels to be axially fixed, and the steel plate and the steel wires form an organic whole body tofirmly fix patella fracture. By means of the steel plate device, a patella body fracture block and a patella inferior pole fracture block of a patient can be in close contact and pressurized fixation,subsequent fracture repair can be accelerated, frequent operation and damage to the inferior pole of the patella of the patient can be greatly reduced, the risk of postoperative complications is effectively reduced, and the rehabilitation speed is increased.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a steel plate device for fracture 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] The team of the inventors has been researching the treatment and rehabilitation of this disease for a long time, and searched and found in the work that the treatment plan for the fracture of the lower pole of the patella in the prior art, such as the patella fracture reduction plate disclosed in the publication number WO2017066682A1, does not require wires to form tension across the fracture site or as the public number CN101912295B disclosed a kind of embracing fixer f...
