Heel bone anatomical form plastic reset bone fracture plate for heel bone fractures

Abstract

The invention relates to a heel bone anatomical form plastic reset bone fracture plate for heel bone fractures, which comprises a hind limb plate for fixing a heel bone on one side of a heel and a forelimb plate for fixing the heel bone on one side of a dorsum pedis, wherein a steel plate is 1.5-2.2 mm in thickness, the hind limb plate is in a bending structure and is 24-30mm in length, and the upper part of the hind limb is a bending bent towards the left along the middle part in an angle of 5-15 degrees; the bone fracture plate further comprises an upper limb plate and a lower limb plate, the upper limb plate and the lower limb plate are respectively fixedly connected with the upper part and the lower part of the hind limb plate, the upper limb plate is 24-28mm in length, the lower limb plate is 48-52mm in length, the front end of the lower limb plate is further fixedly connected with the bottom end of the forelimb plate, an included angle of 90-110 degrees is formed between the front end of the lower limb plate and the bottom end of the forelimb plate, and the forelimb plate is 18-22mm in length; locating holes for locating the specified points of the heel bone are respectively formed at the upper end of the forelimb plate, the front end of the upper limb plate, the upper and the lower ends of the hind limb plate, screw holes are formed on the hind limb plate, the forelimb plate, the upper limb plate and the lower limb plate, and the locating holes and fixing nail pilot holes are round or elliptical holes. The bone fracture plate achieves the optimal effects of reset and internal fixation for various types of heel bone fractures, and has the advantages of being little in damage, convenient to operate and firm for fixation.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a calcaneal anatomical plastic reduction bone plate for calcaneal fractures. Background technique [0002] At present, there are many kinds of calcaneus bone plates clinically, and the most widely used ones are generally anatomically conformable calcaneous plate plates, including titanium and alloy plates, and the bone plate is uniformly provided with fixing nail assembly holes. At present, the most widely used is the "p"-shaped calcaneal plate with a structure similar to that rotated 90 degrees counterclockwise. Such as figure 1 As shown, the right side is a straight plate or "mouth" shaped plate with bifurcated ends, and the left side is an irregular ring-shaped structural plate, which is evenly opened with fixing nail assembly holes. A longitudinal reinforcement beam may also be arranged on the left irregular ring structure plate. The shape of the plate is similar ...

Problems solved by technology

In this way, in the process of using the calcaneus plate, it will cause great harm to the patient

[0004] At the same time, the existing calcaneus plates are all flat plates, which need to be shaped during the operation before they can be used, which will not only prolong the operation time and increase the pain of the patient; at the same time, small deviations in the shaping process will lead to specific fixation. The problem that the nail assembly hole cannot be matched with the specific point of the calcaneus, resulting in deviation of the calcaneus reduction, and in severe cases, the patient will be disabled
