Abstract
The utility model discloses a super-radius fracture adjustable fixer which comprises two cork bases which are fixed through a screw. An end handle convenient to screw in is arranged at the upper end of the screw, and a gasket is arranged at the lower end of the screw. One side of each cork base is provided with a titanium alloy wing plate, and the titanium alloy wings are arrayed in a splay shape. The end portion of each wing plate is in a taper shape. A fixer suitable in size is selected according to a fractured part; a far-end wing plate is pre-bent into a hook shape; the fractured part is restored; the two cork bases and the wing plates are respectively placed in, in an arc shape and attaching to the surface of sclerotin, from the front and the back or the inner side and the outer side of a fractured bone; locking components are embedded in and stringed; the screw is enabled to penetrate through self-screw holes of the two cork bases and is slightly screwed; the fixer is stringed; and then the fractured part is fixed. Another fracture fixer can be planted adjacent to the fractured part at necessary time. The super-radius fracture adjustable fixer is suitable for fixation of fracture around a joint, especially fixation of positions of joints such as a knee joint, a hip joint, an elbow joint, and the like.
Description
Technical field
This utility model belongs to medical instruments field, relates to specifically a kind of holder during for fracture around joint.
Background technology
In surgical operation, the tissues such as the bone that needs after the fracture to separate, ligament are connected and fixed.The fixing means that fracture around joint is commonly used at present is steel plate, steel wire, bundling belt, steel wire and binding band are pricked blood fortune influential, acquiring a certain degree of difficulty around wearing in the steel wire process in addition, and certain risk is arranged, because having joint capsule, tendon to adhere to, be punctured with certain difficulty at the epiphysis position.Abroad, without steel wire, directly with at least 2 bundling belts, the joint of fracturing is bundled.Deng the fracture joint part reset good after, remove bundling belt just can, this bundling belt is easy to use, but expensive, a bundling belt needs 7000-8000 unit, is unfavorable for promoting.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of super radius fracture adjustable fixator is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of super radius fracture adjustable fixator, comprise two collets, two collets are fixed by screw, be provided with the end handle that makes things convenient for precession in the upper end of screw, lower end at screw arranges pad, side at each collet is provided with the titanium alloy wing plate, and the shape of wing plate is " eight " font arranges, and the end of wing plate is taper.
Above-mentioned super radius fracture adjustable fixator is provided with the certainly nail hole of matching with screw on described two collets.
Above-mentioned super radius fracture adjustable fixator, the end of a collet is provided with fin therein.
Adopt technique scheme, this utility model has following advantage: according to fracture site, select suitable big or small holder, first the far-end wing plate is pre-bent to slightly hook-shaped, the reduction of the fracture, with two parts collet and wing plate respectively the curved note bony surface in or medial and lateral forward and backward from skeleton insert, embed snap lock feature, tighten up, the certainly nail hole that screw is penetrated two collets turns gently, tightens up holder, fixing fracture is implanted another fracture fixing apparatus again in the fracture adjacent regions in case of necessity.Far-end of the present utility model is taper, facilitates penetration of tendon and joint capsule, and is little to tissue injury.And this utility model is multiple spot, and other than ring type is fixed, and disturbs little to fracture site blood fortune.On the other hand, be to make the fracture with compressive appropriateness by lifting screw, be unlikely to excessive.Fixing of the joint parts such as fixing of the suitable fracture around joint of this utility model, particularly knee joint pass are old, hip joint, elbow joint.

The specific embodiment
A kind of super radius fracture adjustable fixator as depicted in figs. 1 and 2, comprise two collets, i.e. the first collet 1 and the second collet 2, two collets are fixing by screw 3, be provided with the end handle 4 that makes things convenient for precession in the upper end of screw 3, in the lower end of screw pad 5 be set, be provided with titanium alloy wing plate 6 in a side of each collet, the shape of wing plate 6 is " eight " font arranges, and the end of wing plate is taper.Be provided with the certainly nail hole 7 of matching with screw on described two collets.
Such as Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, this utility model is provided with protruding stupefiedly 8 on the basis of the structure of Fig. 1 in the end of 3 collets of the second collet, prevent two collets displacements and rotation the screw non-locking is forward and backward.
Two within the specific limits bendings of fin of each collet upper flange far-end of this utility model, the end is sharply tapered, can hook bony surface, 2 long 30mm of fin, wide 3 mm, thick 3 mm; Collet size: long 15 mm, wide 10 mm, high 3 mm; Certainly nail bore dia 4 mm on it, interior is screw thread design.Long 20 mm of screw, external diameter 4.5 mm.
The specification of collet of the present utility model and wing plate can also be made different sizes, to adapt to different joint parts.
