Description
Technical field
This utility model relates to reset in bone surgery and fixing medical instruments field, particularly relates to a kind of ankle and foot positioning foresight device.
Background technology
Inferior tibiofibular syndesmosis split, sustentaculum of talus fracture is the common disease of ankle surgery.Inferior tibiofibular joint plays very important effect to ankle cave integrity and elastic maintenance, and it refers to that the attachment to each other of tibiofibula lower end fluffs, and ankle cave broadens, multidirectional outer, the rear dislocation of astragalus.Research proves that astragalus is outwards shifted 1mm, can reduce the contact surface 42% in tibiofibular joint face, and the pressure that bears of local articular surface is doubled.In addition, correlational study finds that external malleolus bears astragalus pressure 1/5, the cripetura of external malleolus and lateral displacement, is that after ankle fracture, traumatic arthritis is modal reason.Sustentaculum of talus bears the gravity in astragalus direction, is also attachment place of calcaneonavicular ligament.Sustentaculum tali fracture belongs to extra-articular fracture, and the sustentaculum tali showing as calcaneus is fracture shape, how with displacement.Because the calcaneus mound portion sclerotin under sustentaculum tali and facies articularis calcanea posterior is strong, the screw of fixing posterior articular facet will provide maximum stability if fix sustentaculum tali simultaneously.
Due to operative approach, art formula and operation time patient body position cause, Inferior tibiofibular syndesmosis split and the sustentaculum of talus reduction of the fracture also carry out spiral shell when fixing, be not under direct-view, operator need carry out screw by means of the clinical experience of oneself to be fixed, even veteran orthopedist, can not ensure higher success rate of operation, after this makes the operation in patients of Inferior tibiofibular syndesmosis split and sustentaculum of talus fracture, ankle joint function is lost comparatively serious and functional rehabilitation is slower.
Utility model content
The ankle positioning foresight device that the purpose of this utility model provides a kind of structure simple, easy to use, can ensure to reset in Jower tibiofibular joint art and fixing accurate direction, avoid the error that traditional subjective judgment brings.
To achieve these goals, the technical solution of the utility model is:
A kind of ankle and foot positioning foresight device, overall in pliers shape, comprise first handle, second handle, the first straight-bar, the second straight-bar, the first pliers head and the second pliers head; Described first pliers head is provided with sleeve, and described second pliers head is provided with tip, and described tip is positioned on the extended line of the centrage of described sleeve; Described first straight-bar one end is slidably connected to described first pliers head, and the other end is rotating is connected to described second handle; Described second straight-bar one end is slidably connected to described second pliers head, and the other end is rotating is connected to described first handle; Described first straight-bar is connected by rotating shaft with the second straight-bar, and can around described axis of rotation.
Further, described first pliers head and the second pliers head being respectively equipped with the first chute and the second chute, slides in one end of described first straight-bar on described first chute, slides in one end of described second straight-bar on described second chute.
Further, also retaining mechanism is provided with between described first handle and second handle.
Further, described retaining mechanism is tooth bar.
Further, described first handle and second handle are also respectively equipped with the first shell fragment and the second shell fragment.
This utility model owing to being provided with tip on the first pliers head, second pliers head is provided with sleeve, and described tip is positioned on the extended line of the centrage of described sleeve, the direction of sleeve pipe is made accurately to point to opposite side tip, and be provided with the first straight-bar of being rotationally connected and second straight, first straight-bar one end is slidably connected to the first pliers head, the other end is rotating is connected to second handle, second straight-bar one end is slidably connected to the second pliers head, the other end is rotating is connected to first handle, drive the first pliers head and the opposing parallel movement of the second pliers head, tip is terminated on tibia bite, sleeve terminates on fibula bite, by sleeve, screw is squeezed in fibula, ensure to reset in Jower tibiofibular joint art and fixing accurate direction, avoid the error that traditional subjective judgment brings.
