Description

Cuboid locking plate

Technical Field

The utility model relates to the field of medical equipment, specifically a cuboid lockplate.

Background

The cuboid is located on the outer side of the foot and between the calcaneus and the fifth metatarsus, cuboid fractures are rare, but once fractured, no steel plate is clinically applicable, the cuboid fractures are often accompanied by compression, proper supporting and fixing are needed, and the Kirschner wire cannot achieve corresponding effects.

While the flat foot may appear as a shortening of the lateral column and a lengthening of the medial column. The cuboid is an important component of the lateral column, and the cuboid osteotomy is increasingly appreciated by ankle surgeons. The cuboid opening osteotomy is an effective means for treating the flat-foot deformity and extending the lateral column, but a steel plate for fixing after the cuboid osteotomy is also lacking clinically, the cuboid osteotomy is usually fixed by screws, but the strength of the screw fixation is insufficient, particularly for osteoporosis patients, the postoperative fixed position is easy to lose, the postoperative function exercise cannot be carried out, the operation recovery time is long, and finally the operation fails.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cuboid lockplate for solve cuboid fracture or cuboid osteotomy postoperative screw fixation poor stability problem. The lockplate is designed to be plate-type and is trapezoid, and the lockplate is fixed on the cuboid through screws, so that the strength and stability of internal fixation after osteotomy and internal fracture fixation are improved.

The purpose of the utility model can be realized by the following technical scheme:

a cuboid locking plate comprises a trapezoidal locking plate body, wherein the locking plate body comprises a locking plate outer side end, a locking plate distal end, a locking plate inner side end and a locking plate proximal end which are integrally formed, a plurality of fixing holes used for fixing the locking plate on a cuboid are formed in the locking plate body, and the directions of the locking plate proximal end and the locking plate distal end are consistent with the direction of a first metatarsus.

Furthermore, the outer side end of the locking plate is shorter than the inner side end, and the whole steel plate is of a trapezoidal structure.

Furthermore, each section of the outer side end of the locking plate, the distal end of the locking plate, the inner side end of the locking plate and the proximal end of the locking plate is provided with 3 universal locking holes, and two holes on the edge are overlapped with holes on the edge of an adjacent section, so that the total number of the holes is 8.

Furthermore, the middle of the locking plate is designed to be hollow, and operations such as bone grafting, reduction and the like can be performed through the hole.

Furthermore, the first fixing hole, the second fixing hole, the third fixing hole and the fourth fixing hole are distributed in a straight line shape along the steel plate.

Furthermore, internal threads are arranged in the first fixing hole, the second fixing hole, the third fixing hole and the fourth fixing hole.

Further, it is characterized in that: the locking plate is made of titanium alloy material.

The utility model has the advantages that:

1. the utility model makes the fixation after osteotomy more stable and reliable, adopts the steel plate design, has large intensity, is beneficial to the early functional exercise, and shortens the postoperative recovery time;

2. the utility model has better fixation effect on osteoporosis and cuboid fracture, adopts the design of hidden edge, reduces the stimulation to soft tissue, adopts the anatomical design of the locking plate, is convenient for osteotomy and anatomical reduction after fracture, and does not need to pre-bend the steel plate in the operation;

3. the utility model has a plurality of screws to fix the bone block, so that the fixation is more stable and firm, the current situations of fixing the cuboid fracture and the cuboid osteotomy without steel plates are changed, the adaptation disease range of the cuboid osteotomy is expanded, and the theoretical system of the flat-foot operation is simplified;

4. the utility model relates to an application scope is wide, can be used to the operation treatment of cuboid fracture and flat foot outer column extension, and the operation procedure that will cut the bone is moreover standardized, the actual operation of being convenient for.
