The specific embodiment
The utility model discloses a kind of dynamic property traction external fixer, with can keep joint and the reduction of the fracture stable in, carry out the joint active movement.
Below in conjunction with the accompanying drawing among this utility model embodiment, the technical scheme among this utility model embodiment is clearly and completely described, obviously, described embodiment only is this utility model part embodiment, rather than whole embodiment.Based on the embodiment in this utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of this utility model protection.
See also Fig. 1, the dynamic property that Fig. 1 provides for this utility model embodiment is drawn the structural representation of external fixer.
The disclosed dynamic property of this utility model embodiment traction external fixer is mainly used in fracture or fracture companion dislocation in the finger proximal phalangeal joints, can keep joint and the reduction of the fracture stable in, carry out the joint active movement.This dynamic property traction external fixer comprises outer fixed traction bow 1, countertraction pin 5, the pin 4 that resets, rubber band 2 and pull needle 3.
Wherein, countertraction pin 5 and outer fixed traction bow 1 are connected with the hinge form, be that side para-ligament starting point (the anteroposterior position X-ray shows the bone projection small in ends of proximal phalanx neck) is parallel to proximal phalangeal joints and penetrates the proximal phalanx head, effect: 1, countertraction in center, proximal phalanx head side.When 2, proximal phalangeal joints is movable centered by this pin.
The pin 4 that resets is arranged on the outer fixed traction bow 1, be parallel to countertraction pin 5 in center, middle phalanx near-end side and penetrate middle phalanx, two arms of outer fixed traction bow 1 can will reset pin 4 to palmar or dorsal part persistent pressure according to the fracture dislocation direction during application, keep that the joint centration resets and the pressurization of sclerite stable.
Two rubber bands 2 are arranged on the outer fixed traction bow 1, and pull needle 3 is parallel to countertraction pin 5 in center, middle phalanx far-end side and penetrates middle phalanx, and its two ends link to each other with rubber band 2, play draw.This utility model is converted into the tension force of rubber band 2 the longitudinal traction power in joint and keeps the joint and the compressive stress of the reduction of the fracture.
