Description

Technical Field

[0001] The utility model relates to the technical field of pressurized steel plates, in particular to a novel pressurized steel plate based on a three-dimensional triangular structure of the distal end of the humerus. Background Art

[0002] The distal humerus has a complex structure, forming a three-dimensional triangular structure based on the lateral column, medial column, and pulley.

[0003] With the continuous development of social economy, the incidence of distal humeral fractures has continued to rise. In C-type distal humeral fractures (AO / ASIF) caused by high-energy violence, the three-dimensional triangular structure of the distal humerus is destroyed, seriously affecting the function of the elbow joint. The surgery is difficult, and postoperative functional recovery is difficult. The fixation of distal humeral fractures is difficult. Existing compression plates have the following disadvantages:

[0004] (1) Parallel plates are often used for fixation of distal humeral fractures. However, the stability of parallel plates is relatively poor and their effect on complex fractures is not as good as that of vertical plates. In terms of functional recovery, they may not be able to fully restore the normal function of the distal humerus, such as limited range of motion.

[0005] (2) Existing pressurized steel plates lack good structural strength, have poor bending and torsional resistance, and are easily deformed when subjected to large forces. Utility Model Content

[0006] The purpose of the utility model is to provide a new type of compression steel plate based on the three-dimensional triangular structure of the distal end of the humerus, so as to solve the existing problems raised in the above background technology.

[0007] The utility model discloses a novel pressurized steel plate based on the three-dimensional triangular structure of the distal end of the humerus, comprising the distal end of the humerus, characterized in that: an outer plate is installed on the outer side of the distal end of the humerus, an inner plate is installed on the inner side of the distal end of the humerus, a Y-shaped portion is provided at the bottom of the outer plate, a plurality of screw locking holes are opened on the Y-shaped portion, a plurality of pressurized locking holes are opened on the surface of the outer plate, slots are opened at both ends of both sides of the outer plate and both ends of both sides of the inner plate, vertical reinforcing strips are fixedly connected on both sides of the outer plate and both sides of the inner plate, a plurality of transverse reinforcing strips are evenly fixedly connected on the surface of the outer plate and the surface of the inner plate, a convex portion is provided in the middle of the vertical reinforcing strip, and a plurality of circular holes are opened on the surface of the outer plate and the surface of the inner plate.

[0015] The utility model is a new type of compression steel plate based on the three-dimensional triangular structure of the distal humerus. The difference from the existing technology is that:

[0016] 1. The lateral and medial plates are respectively attached to the inner and outer columns of the distal humerus and placed in parallel. The Y-shaped portion of the distal lateral plate is fixed to the front and back of the pulley with screws, forming a triangular structure that conforms to the distal morphology and facilitates intraoperative shaping. This new steel plate not only fixes the inner and outer sides of the distal humerus, but also forms a new arch bridge structure based on the distal articular surface, providing stronger fixation and fracture end compression, allowing for earlier functional exercise after reduction.

[0017] 2. By setting notches and circular holes on the outer and inner plates, the weight of the material is reduced while its surface area is increased, the rigidity is improved, and vertical and horizontal reinforcement strips are set to improve the bending and torsional resistance of the pressurized steel plate, making it less likely to deform when subjected to greater force.
