Orthopaedic implant locking elastic bone fracture plate

Abstract

The invention discloses an orthopaedic implant locking elastic bone fracture plate and belongs to medical apparatuses. The orthopaedic implant locking elastic bone fracture plate comprises a bone fracture plate, wherein a locking hole is formed in the bone fracture plate. The orthopaedic implant locking elastic bone fracture plate is characterized in that: the locking hole in the bone fracture plate is a taper thread hole; a screw matched with the taper thread hole is a taper screw; the taper thread hole and the taper screw are connected through taper screw threads; and slots are formed in the two sides of the taper thread hole. After the screw and the bone fracture plate are connected, an elastic effect is achieved between the screw and the bone fracture plate. Because the taper screw thread connection is adopted, the slots are formed in the two sides of the taper screw hole, and the elastic effect is achieved between the screw and the bone fracture plate, the elastic modulus of the traditional implant material can be compensated, the fatigue resistance of a system can be improved, the corrosion of a screw clearance can be reduced, and the bone fracture plate has a very good effect on the promotion of the healing and the rehabilitation of a bone fracture. The orthopaedic implant locking elastic bone fracture plate is reasonable in structure, simple in manufacture and ideal in effect.

Description

technical field [0001] The invention belongs to the category of medical devices, in particular to an orthopedic implant locking elastic bone plate. Background technique [0002] The existing orthopedic implant locking bone plates are generally made of titanium alloy and stainless steel with a high modulus of elasticity. There are locking holes on the locking bone plate, and the locking holes form a rigid connection with the bone screws. The elastic effect is not ideal, and there is a stress shielding effect in the later stage. During the fracture healing process, the fatigue resistance of the system is low; moreover, the gap between the threads after the locking hole and the screw is connected is prone to corrosion, which is not conducive to fracture healing and rehabilitation. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide a locking elastic bone plate for orthopedic implants with a more re...
