Problems solved by technology

[0002] Most hyoid fractures of the calcaneus require surgical reduction and internal fixation. At present, screws, wires and other fixation methods are commonly used, and then gypsum fixation is still assisted after surgery, because the above-mentioned fixation has problems such as screw loosening and wire cutting, which lead to failure. At the same time The steel wire needs to form buttons on the soles of the feet, which will put pressure on the skin of the soles and easily lead to pressure ulcers
Internal fixation with steel plates requires open reduction and placement, which causes large trauma and is not specially used for this type of fracture, and the fixation is unreliable

Embodiment 1

[0031] The fixed steel plate 1 is bent in an arc shape and fits the shape of the calcaneus, and a plurality of threaded holes 2 are arranged on the fixed steel plate 1, wherein a central screw 4 extending vertically downward is arranged in the threaded hole 2 at the center of the bending position. Side screws 5 are respectively provided on both sides of the central screw 4, and the lateral screws 5 and the central screw 4 are arranged in a dislocation and crosswise manner;

Embodiment 2

[0033] The fixed steel plate 1 is bent in an arc shape and fits the shape of the calcaneus, and a plurality of threaded holes 2 are arranged on the fixed steel plate 1, wherein a central screw 4 extending vertically downward is arranged in the threaded hole 2 at the center of the bend. A lateral screw 5 extending horizontally is provided on one side of the screw 4. The lateral screw 5 passes through the limit hole 10 and is cross-fitted with the central screw 4.

Embodiment 3

[0035] The fixed steel plate 1 is bent in an arc shape and fits the shape of the calcaneus, and a plurality of threaded holes 2 are arranged on the fixed steel plate 1, wherein a screw 3 extending vertically downward is arranged in the threaded hole 2 at the center of the bending position. The screw 3 A through hole 9 is set in the middle, an L-shaped connecting plate 6 is set at the top of the bend, the screw 3 is inserted into the calcaneus after passing through the connecting plate 6 and the threaded hole 2, a puncture hole 8 is set on the connecting plate 6, and the fixing needle 7 passes through the puncture. The hole 8 is then inserted into the calcaneus and then passes through the through hole 9 to be fixed with the screw 3;

[0036] In the present invention, the calcaneus is fixed by the fixing method of the miniature steel plate combined with the screw 3, which can not only be implanted by a minimally invasive operation, but also can realize strong fixation, which is b...

Abstract

The invention discloses an internal fixing device for calcaneal fracture, a fixing steel plate is bent smoothly in an arc shape and is attached to the surface of the calcaneal tuberosity, a plurality of threaded holes are formed in the fixing steel plate, one threaded hole is formed in the center of the arc-shaped bend, and a bone penetrating fixing assembly penetrates through the threaded holes and then penetrates into the calcaneus to be matched with the fixing steel plate to fix the calcaneus. Screws penetrate through the threaded holes and then penetrate through the calcaneus to be matched with the fixing steel plate to fix the calcaneus. The connecting plate is L-shaped, one end of the connecting plate is arranged at the top of the bent position of the fixing steel plate, the screw penetrates through threaded holes in the center of the connecting plate and the center of the bent position and then vertically extends downwards to pierce the calcaneus, the other end of the connecting plate extends downwards, a puncture hole is formed in the connecting plate, and the fixing needle penetrates through the puncture hole and then horizontally extends to pierce the calcaneus. The calcaneus is fixed in the fixing mode that the micro steel plate is combined with the screws, minimally invasive surgery imbedding can be achieved, firm fixing can be achieved, and early movement of a patient is facilitated.

Description

technical field [0001] The invention relates to the technical field of calcaneus internal fixation devices, in particular to an internal fixation device for calcaneal fractures. Background technique [0002] Most calcaneus hyoid fractures require surgical reduction and internal fixation. At present, the commonly used fixation methods are screws, wires, etc., and then post-operative plaster fixation is still used, because the above-mentioned fixation has problems such as screw loosening and wire cutting, which lead to failure. The steel wire needs to be fixed with buttons on the sole of the foot, which can put pressure on the skin of the sole of the foot and easily lead to pressure ulcers. Plate internal fixation requires open reduction and placement, which is traumatic and is not specially used for such fractures, and the fixation is unreliable. [0003] Therefore, a fracture internal fixation device specially used for the root hyoid bone has become an urgent problem to be ...
