Abstract
A clavicle external fixator comprises clavicle grippers, fixation bolts of the clavicle grippers, fixation nuts of the clavicle grippers, a fixation link, a gimbal, bolts, an adjustment link and adjustment nuts. When the utility model is used, the clavicle grippers are arranged in pairs and respectively on both ends of the clavicle external fixator. The body of the adjustment link, i.e. each of the two ends of the clavicle gripper is provided with an adjustment nut, wherein a gimbal is arranged between the fixation link and the adjustment link, each of the connecting points of the gimbal is provided with a bolt used for fixation. With the technique of clavicle external fixator provided by the utility model, positioning and fixation of the fractured site of the bone can be carried out in favor of the healing of the bone without influence on the activity of the patient, and the utility model has minor surgical trauma, easy operation, lower cost, contribution to the exercises in the early phase, and especially the simple mechanism with reliable efficacy, low cost and good clinical application.
Description
Technical field: this utility model relates to bone surgery equipment, relates in particular to the fixedly clavicle external fixator of usefulness of a kind of clavicular fracture.
Background technology: in the clavicular fracture fixing operation, normally used external fixation mainly is that figure of eight external plaster fixation method reaches two circle fixations now, but all there is the fixing unstable problem that also influences activity and exercise in these two kinds of fixed forms.Chinese patent ZL90202729.4 discloses a kind of double-jaw single-arm type clavicle external fixator, though can fix relatively more firmly, because single armed is regulated inconvenience, brings many troubles to operation technique.
The utility model content: the purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of clavicle external fixator is provided, and can make operation easy, processing ease, and wound is little, and is safe and reliable.Clavicle external fixator described in the utility model includes that clavicle grasps pawl, grasps the pawl fastening bolt, grasps the pawl clamp nut, stationary links, universal joint, screw, adjusting connecting rod and adjusting nut form.It is the three-pawl type structure that said clavicle grasps pawl, and a side is that two parallel pawls are fixedly connected, and corresponding with it opposite side is provided with a motor-driven pawl.Said motor-driven pawl and two fixed claws flexibly connect, and are provided with between motor-driven pawl and fixed claw and grasp the pawl fastening bolt, grasp the pawl fastening bolt and are provided with and grasp the pawl clamp nut.During concrete the use, said clavicle grasps pawl and should be provided with in pairs, is separately positioned on the two ends of clavicle external fixator described in the utility model.The two ends of said clavicle external fixator, an end is a stiff end, is connected and fixed connecting rod; The other end is the adjustable side, connects to regulate connecting rod.Said stationary links, to compare length shorter with regulating connecting rod, and an end of stationary links connects clavicle and grasps pawl, and the other end of stationary links becomes U-shaped, is provided with screw hole.Said adjusting gonnecting rod body is provided with screw thread, and is identical with stationary links, also is at one end to become U-shaped, is provided with screw hole.On the body of rod of regulating connecting rod, also be the both sides that grasp pawl at clavicle, respectively be provided with an adjusting nut, said stationary links is provided with universal joint with the adjusting connecting rod is middle, and each junction point of universal joint is provided with the screw of fixedly connected usefulness.
Use clavicle external fixator technology described in the utility model, clavicular fracture is implemented positioning and fixing, helping union of fracture does not influence the activity of trouble limb.Especially use technology described in the utility model, operation wound is little, processing ease, and relative cost is lower, helps early exercise, and simple in structure, reliable, cheap, clinical practice is better
Description of drawings: accompanying drawing is the structural representation of clavicle external fixator described in the utility model.
The 1-clavicle grasps pawl 2-and grasps pawl fastening bolt 3-and grasp pawl clamp nut 4-stationary links 5-universal joint 6-screw 7-and regulate connecting rod 8-adjusting nut
The specific embodiment: referring now to accompanying drawing, specify as follows in conjunction with the embodiments: clavicle external fixator described in the utility model includes that clavicle grasps pawl 1, grasps pawl fastening bolt 2, grasps pawl clamp nut 3, stationary links 4, universal joint 5, screw 6, regulates connecting rod 7 and adjusting nut 8 is formed.Said clavicle grasps pawl 1 and is the three-pawl type structure, and a side is that two parallel pawls are fixedly connected, and corresponding with it opposite side is provided with a motor-driven pawl.Said motor-driven pawl and two fixed claws flexibly connect, and are provided with between motor-driven pawl and fixed claw and grasp pawl fastening bolt 2, grasp pawl fastening bolt 2 and are provided with and grasp pawl clamp nut 3.During concrete the use, said clavicle grasps pawl 1 and should be provided with in pairs, is separately positioned on the two ends of clavicle external fixator described in the utility model.The two ends of said clavicle external fixator, an end is a stiff end, is connected and fixed connecting rod 4; The other end is the adjustable side, connects to regulate connecting rod 7.Said stationary links 4, to compare length shorter with regulating connecting rod 7, and an end of stationary links 4 connects clavicle and grasps pawl 1, and the other end of stationary links 4 takes the shape of the letter U, and is provided with screw hole.Said adjusting connecting rod 7 bodies of rod are provided with screw thread, and are identical with stationary links 4, are at one end to take the shape of the letter U also, are provided with screw hole.On the body of rod of regulating connecting rod 7, also be the both sides that grasp pawl 1 at clavicle, respectively be provided with an adjusting nut 8, be provided with universal joint 5 in the middle of said stationary links 4 and the adjusting connecting rod 7, each junction point of universal joint 5 is provided with the screw 6 of fixedly connected usefulness.Use clavicle external fixator technology described in the utility model, clavicular fracture is implemented positioning and fixing, helping union of fracture does not influence patient's activity.Especially use technology described in the utility model, operation wound is little, processing ease, and relative cost is lower, helps early exercise, and simple in structure, reliable, cheap, clinical practice is better.
