Medical hinge type ring-shaped pressure steel plate with lock for department of orthopaedics

Abstract

The invention provides a medical orthopaedics hinge ring lock compression plate which comprises a hinge axes compression plate, a hinge axes compression plate lock screw rod, an edge hinge ring lock compression plate, an invisible hinge ring lock compression plate, a hinge lock compression screw rod, and a compression screw nail. The medical orthopaedics hinge ring lock compression plate is made of medical alloy or titanium alloy includes a child type and an adult type, and is made into the compression plate suitable for collarbone, rib, shoulder bone, ulna, spoke bone, thighbone, shinbone and splinter bone according to the human anatomy structure, and the single-hinge or multi-hinge medical orthopaedics hinge ring lock compression plate can be applied according to the fraction condition. The medical orthopaedics hinge ring lock compression plate has simple operation, better fixation with hard shedding and breaking, and better position and wire alignment, reduces the rejection reaction of the human body, can fully replace the fixation of the fracture by the prior fixing instrument (kjeldahl needle, steel plate, interlocking intramedullary needle, wire binding, and the like), and accords with the modern osteology principle.

Description

technical field [0001] The invention belongs to disposable medical consumables, in particular to a medical orthopaedic hinge-type annular locking compression plate for human body (clavicular, rib, humerus, radius, ulna, femur, tibia, fibula) fractures. Background technique [0002] In the classic treatment of fractures, in addition to traditional Chinese medicine bone setting, Western medicine orthopedic manipulation reduction, plaster or splint external fixation, and traction, surgical open reduction and internal fixation are often used. For long bones and flat bones, the fixation methods are steel plates, screws, Kirschner wires, interlocking intramedullary needles, wire bundles or compound fixation with multiple devices. These clinically commonly used internal fixation devices must be implanted into human bone. There are many short-term and long-term complications. Due to factors such as internal rejection, poor fixation, and osteoporosis, individual fracture ends may hav...

AI Technical Summary

Problems solved by technology

[0005] 2. Susceptibility to infection: Most of the Kirschner wire internal fixation has its distal end exposed outside the human body, which is prone to local skin infection and pain

[0006] 3. Easy to cause joint stiffness: Kirschner wires are generally inserted into human bone from the outside of the joint, often restricting the movement of one side or the other side of the joint, resulting in joint stiffness

[0007] 4. Poor alignment (functional position, anatomical position): Internal fixation of Kirschner wires, whether one or two cross-fixed, is prone to shift and dislocation, especially for oblique, spiral, comminuted For fractures, the fixation of Kirschner wires usually needs to be tied with steel wires

[0012] 1. Bad alignment

[0013] During open reduction, due to fractures, local changes in the body, tissue edema, congestion, infection, some patients are delayed in seeking medical attention, and even malunions occur. For fractures, comminuted fractures, and oblique fractures, additional steel wires or screws should be used for fixation. Straight-line plate fixation often occurs (forward, backward, inward, outward, upward, or downward). Bad position and alignment, failure to reach the functional position, malunion, and affecting motor function

[0014] 2. The steel plate is broken

[0019] For some particularly complex bone fractures, steel plates, Kirschner wires, interlocking intramedullary nails are often required, and steel wires or screws are used to fix them on the bone. The more complicated the fixation, the more unfavorable the growth of callus

[0020] In addition, the above four fixation methods are not stable for the fixation or repair of new bone grafts or fracture fragments after fractures, and are easy to fall off, resulting in bone defects in the backbone. sequestrum or osteomyelitis
