Description
Technical Field
The utility model relates to an orthopedic lockplate, specifically an orthopedic lockplate of shin bone distal end inboard osteotomy.
Background
Ankle arthritis is a common ankle disease, and the major cause of the ankle arthritis is varus in Asians. In the early stage of the disease, the ankle joint is usually inverted over time due to habitual sprain of feet. The patients mainly show the varus deformity of the ankle joint, accompanied by swelling and pain, limited movement and difficult walking, which seriously affects the daily life of the patients. Deformities may be corrected by surgery at this time.
At present, only one ankle joint replacement prosthesis is clinically used in China, the price is high, in addition, part of patients are younger, and the replacement of joints in early stage is not good for the ankle joint replacement prosthesis. Therefore, a significant proportion of patients choose to treat ankle arthritis by osteotomy. However, the existing clinical steel plate specially used for the ankle osteotomy is lacked, the common medial malleolus steel plate used for fixing the fracture is used, the inner side curvature of the tibia is changed after the osteotomy is opened due to the anatomical design of the steel plate according to normal people, and the opening distance can be retracted when the steel plate is opened, so that the expected effect of the operation cannot be achieved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an orthopedic lockplate of shin bone distal end inboard osteotomy for solve the problem that no ankle goes up the osteotomy board, the osteotomy board is board-like, is the arc, fixes the osteotomy board on the shin bone through the screw, improves the intensity and the stability of internal fixation after the osteotomy.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides an orthopedic lockplate of shin bone distal end inboard osteotomy, orthopedic lockplate includes the osteotomy board main part, be equipped with the osteotomy board near-end in the osteotomy board main part, be equipped with first fixed orifices on the osteotomy board near-end, be equipped with the cab apron in the osteotomy board main part, be equipped with the sliding connection hole on the cab apron, be equipped with the osteotomy board distal end in the osteotomy board main part, be equipped with the second fixed orifices on the osteotomy board distal end, the proximal end of osteotomy board and the distal end direction of osteotomy board are unanimous with the shin bone direction for fix the osteotomy.
Furthermore, the space geometry of the contact surface of the osteotomy plate and the tibia is matched with the surface form of the tibia, so that the fixation is more stable, the osteotomy plate does not need to be bent by a screw in an operation, and pre-bending is not needed before the operation, further damage to bone in the screw fixation process due to non-conformity of the osteotomy plate is avoided, even tibia fracture occurs, particularly for patients with osteoporosis, the operation is facilitated, and the operation time is shortened.
Furthermore, the proximal end of the osteotomy plate is provided with at least 3 first fixing holes, the distal end of the osteotomy plate is provided with at least 7 second fixing holes, and the osteotomy plate is fixed at two ends, so that the stress of the osteotomy plate is minimum.
Furthermore, the first fixing holes are distributed in a straight line, the second fixing holes are distributed in a scattered mode, the sliding connecting holes are convenient to fix after osteotomy, and the distance stretched after osteotomy is prevented from being lost.
Furthermore, threads are arranged in the first fixing hole, the sliding connecting hole and the second fixing hole, counter bores are arranged in the first fixing hole, the sliding connecting hole and the second fixing hole, and the head of the fixing screw is sunk into the counter bores.
Further, the main body of the osteotomy plate is made of titanium alloy material.
The utility model has the advantages that:
1. the utility model has simple structure, adopts hidden edges, reduces stimulation to soft tissues, adopts anatomical design for the osteotomy plate, is arc-shaped, is convenient for anatomical reduction after osteotomy, does not need to pre-bend the steel plate in the operation, reduces operation difficulty, fixes the far-end bone block by transversely different extension lengths, solves the hallux valgus deformity with different degrees, fixes the far-end bone block by screws, ensures that the osteotomy is fixed stably and firmly, is favorable for early functional exercise, shortens postoperative recovery time, and is suitable for practicality;
2. the utility model discloses orthopedic lockplate has solved and has not had the problem that is exclusively used in the osteotomy board on the ankle clinically, has enlarged the adaptation disease scope of osteotomy operation on the ankle, has simplified the theoretical system of osteotomy operation on the ankle. The application range is wide, the ankle joint treatment device can be used for the surgical treatment of the ankle arthritis in the early, middle and late stages, and the ankle osteotomy operation is programmed, standardized and convenient for actual operation.
