Background
In clinical work of ankle surgery, calcaneus fracture is relatively common, and when incision reduction surgery is performed, anatomical reduction is required to be optimal, so that the postoperative function of a patient is close to that of a normal person as much as possible. Calcaneal fractures are less likely to be nonunion, but often have abnormal healing, i.e., high loss, joint surface mismatching, lateral bulging, and abnormal force lines, and therefore require more anatomical reduction. Methods for intraoperative reduction of bone mass currently typically employ tools such as distractors, k-wire periosteum dissectors, and tissue clamps. However, because the calcaneus bone structure is complex, sometimes the operation is difficult by using the above-mentioned apparatus, and the anatomical reduction of the displaced bone block is difficult in the operation. Especially when the heel bone fracture is two or more parts in front and back, the current apparatus is difficult to play a good reset effect and the operation difficulty is very big, the operation time is increased, and the repeated operation can also cause trauma to peripheral nerve blood vessels, resulting in postoperative complications. In addition, the kirschner wire, the vascular forceps and the tissue forceps are used as a resetting device, on one hand, the holding force is weak, and the bone block is easy to slip off during the operation in the operation, so that the repeated operation in the operation is caused; on the other hand, since they are not dedicated compression reduction devices, there is a high possibility that these instruments are damaged or cause a medically-derived fracture in surgery when they are improperly used. The existing calcaneus reduction device also has the defects of difficult axial reduction, insufficient holding force and the like.
