Embodiment Construction

[0019] Attached below figure 1 to attach Figure 5 The present invention will be further described.

[0020] The calcaneus auxiliary reduction and fixation device for calcaneus fracture closure or minimally invasive reduction and internal fixation includes right outer splint 1 or left outer splint 2, right inner splint 3 or left inner splint 4, and is used to fix right outer splint 1 and left outer splint. The right inner splint 3 or the driving device that fixes the left outer splint 2 and the left inner splint 4, and the driving device drives the right outer splint 1 and the right inner splint 3 or fixes the left outer splint 2 and the left inner splint 4 to move relative to each other to form the right outer splint 1 The outer contours of the plate body I 11 and the plate body III 31 constituting the right medial splint 3 correspond to the shape of the lateral or medial wall of the right calcaneus; The outer contour of the plate body IV 41 corresponds to the shape of the ...

Abstract

The invention relates to an auxiliary calcaneus reduction fixing device for calcaneus fracture occlusion or minimal invasion reduction internal fixation. The auxiliary calcaneus reduction fixing device for calcaneus fracture occlusion or minimal invasion reduction internal fixation comprises a right outer side splint or a left outer side splint, a right inner side splint or a left inner side splint and a driving device used for fixing the right outer side splint and the right inner side splint or fixing the left outer side splint and the left inner side splint, wherein the driving device drives the right outer side splint and the right inner side splint or fixing the left outer side splint and the left inner side splint to move relatively. Compared with an existing operation method, the auxiliary calcaneus reduction fixing device does not need to carry out open reduction and internal fixation, thereby having the advantages of a small wound and accurate anatomical reduction. The right outer side splint 1 or the left outer side splint 2, and the right inner side splint 3 or the left inner side splint 4 correspond to the outer side wall or inner side wall of the right calcaneus in shape, and therefore the auxiliary calcaneus reduction fixing device has the advantages of being firm in fixation, few in complication, free of a second operation, small in pain of a patient and the like, and calcaneus fracture is made to be back to minimally invasive therapy.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary reduction and fixation device for treating calcaneal fractures under the guidance of CT. Background technique [0002] Calcaneal fracture is a common clinical disease. The existing treatment technique is open reduction and internal fixation. There are complications such as large trauma to the patient, incision non-union, and repeated trauma when the steel plate is removed in the second operation, which aggravates the pain and economic burden of the patient. At present, there is no CT-guided closed reduction and internal fixation of calcaneal fractures and auxiliary reduction and fixation devices. Contents of the invention [0003] In order to overcome the shortcomings of the above technologies, the present invention provides a calcaneal auxiliary reduction and fixation device with less trauma and firm fixation for calcaneal fracture closure or minimally inv...
