Embodiment Construction

[0015] The present invention comprises splint 1, handle 2, rotating shaft 3, pressing ball 4, spring 5.

[0016] As shown in the figure, the two splints 1 are rectangular, and the two splints 1 are respectively connected with the two handles 2. The two handles 2 cross at the junction, and the intersections are connected by the rotating shaft 3 to form a clamp structure. One side of the rotating shaft 3 The board faces of the two splints 1 are parallel and opposite, and the two handles 2 on the other side of the rotating shaft 3 are opposite. Hold the two handles 2 tightly, and the two splints 1 move to the middle through the rotating shaft 3, which can put pressure on both sides of the calcaneus placed between the two splints 1, and perform the reduction operation of the calcaneus fracture, so as to correct the widening deformity of the calcaneus the goal of.

[0017] As shown in the figure, there are a plurality of round holes evenly distributed on the opposite board surface...

Abstract

The invention relates to a calcaneus bone fracture compression restoration device, which belongs to the technical field of orthopedic medical appliances and is used for compression restoration on the calcaneus bone fracture. The calcaneus bone fracture compression restoration device has the technical scheme that a clamp type structure is used; the splint surfaces of two splints are parallel and opposite; the splints are clamped at two sides of the calcaneus to be restored; two handles are tightly held; the two splints exert the pressure to the middle from the two sides of the calcaneus for performing; the calcaneus bone fracture restoration operation is performed; and the goal of correcting the calcaneus widening malformation is achieved. Press balls and springs arranged on the two splints can achieve high fitness on the bone fracture part; the integral uniform flexible compression is performed along with different heights of the bone fracture position; and a good compression restoration effect is achieved. The calcaneus bone fracture compression restoration device belongs to the initiate of the a calcaneus bone fracture restoration appliance, and has the advantages that the structure is simple; the use is convenient; the pressurization is uniform and reliable; and the restoration effect is good. The calcaneus bone fracture can be subjected to restoration operation in the soft closed state of skin, muscles and the like; the calcaneus widening malformation is corrected; the defects of a conventional operation method is are avoided; and adverse conditions are created for performing minimally invasive surgery.

Description

technical field [0001] The invention relates to a pressure reduction device for treating calcaneal fractures, belonging to the technical field of orthopedic medical devices. Background technique [0002] Calcaneal fractures are the most common tarsal fractures. Mostly due to falling from a height or a car accident, the heel is hit by an external force. Among them, intra-articular fractures account for about 60%-75% of calcaneal fractures, and improper treatment can lead to long-term pain and even loss of function of the foot. At present, the surgical options for calcaneal fractures are mainly divided into traditional open reduction and internal fixation and minimally invasive closed reduction and internal fixation. Regardless of the surgical procedure, it is necessary to restore the width and height of the calcaneus (Bohler’s angle), correct the varus and valgus deformities of the calcaneus, and reconstruct the anatomical shape of the posterior articular surface of the sub...
