Description
This utility model relates to a kind of surgical medical equipment, the especially a kind of fixed double-jaw single-arm type clavicle of clavicular fracture external fixator that is exclusively used in.
The existing external fixation of clavicular fracture has " ∞ " shape plaster bandage fixation and Shuan Quan (being surrounded by the binder circle of Cotton Gossypii) fixation.These two kinds of methods all exist fixing not firm, influence the active deficiency of shoulder joint.
The purpose of this utility model provides a kind of simple in structure, fixed, does not influence the active double-jaw single-arm type clavicle of upper extremity function external fixator again.
This utility model is fixed two holding claws by movable belled single-arm shift bracket two ends and is formed, holding claw comprise one fixing, one active in the circular arc pawl.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is this utility model structural representation.
This utility model is made up of holding claw (1), bolt (6), single-arm shift bracket (5), nut (2), rubber cap (3), screw (4).Movable socket is a hollow circular with the fastening single-arm shift bracket of screw (4) (5) two ends also, and also fastening with nut (2) by the axle head on two holding claws (1) top respectively, pawl axle top and bolt protrude part and all put rubber cap (3); Holding claw (2) is made of two interior circular arc pawls, and fixed claw and upper axial are connected as a single entity, and a movable claw can be made 180 ° of circular arcs by fixed axis and rotate, and fixes with bolt (6), and each pawl has two cat's paws.
During use, earlier two holding claws are unclamped, fixing far away, the near fracture end of clavicle respectively, active pair of pawl makes it to fix with fracture end (the steady fracture end of firm grip) by bolt, puts single-arm shift bracket after the reduction of the fracture, regulates the length (screw in or screw out) of support, tighten the nut that is inserted in the holding claw axial region, holding claw and single-arm shift bracket are fixed, and the screw of tightening then on the support is fixed the length of arm, and the two ends of arm do not rotate.Screw rod end and holding claw axle top all put rubber cap, to avoid skin injury.
This clavicle external fixator is simple in structure, and is fixed, easy to operate, and do not influence the upper extremity function activity, very practical.
