Abstract
A malformation-preventing adjusting corrector for the part between the thumb and the index finger comprises nuts and screws. The technical key points are that the adjusting nuts with internal threads are respectively in threaded connection with the screws, the adjusting nuts are arranged on the two sides of the corrector, the outer end of one screw is fixedly connected with a fixed groove-shaped finger bracket, and the outer end of the other screw is movably connected with a rotary adjustable type groove-shaped finger bracket through a hinge structure. When the corrector is used, arc grooves of the two groove-shaped finger brackets are respectively clamped to the thumb and the index finger, the nuts are rotated to adjust the lengths of the screws to enable the two groove-shaped finger brackets to tightly support the thumb and the index finger, and an angle of the groove-shaped finger bracket on the index finger can be adjusted through the hinge structure. When the groove-shaped finger bracket on the index finger is tightly matched with the index finger, the screws are screwed up and fixed. The malformation-preventing adjusting corrector is suitable for a patient with the part between the thumb and the index finger damaged to wear in a post-operation fixing period, an early injured period and a recovery period and can effectively prevent and cure contracture malformation of the part between the thumb and the index finger.
Description
Technical field
This utility model belongs to technical field of medical instruments, and specifically a kind of preventing regulates orthosis because of the anti-deformity of tiger's jaw of tiger's jaw contracture deformity.
Background technology
At present, tiger's jaw contracture is one of common difficult problem of hands surgery.Tiger's jaw is caused the common cause of tiger's jaw contracture deformity because of wound, deep burn, often cause irreversible cicatrization, thumb and first finger cicatricial adhesion, tissue follows the string, make the angle between thumb and first finger be less than 90o, have a strong impact on the abduction of thumb and to palm function, cause hands dysfunction, larger on patient's live and work impact.Tiger's jaw contracture also sees hoku-bit injectable drug and causes adductor pollicis contracture and congenital adductor pollicis strap.The pathomechanism of traumatic tiger's jaw contracture has skin scar contracture, subcutaneous fascia contracture, adductor pollicis contracture, flexor pollicis brevis contracture, the first capsulae articulares carpometacarpeae contracture and the first carpometacarpal joints pathological changes.Traumatic tiger's jaw contracture still can be secondary to after median nerve injury, and thumb can not palmar abduction, or the distally broken ends of fractured bone after flexor pollicis longus tendon injury, and thumb is sticked to interior receipts position.Flexor pollicis brevis contracture and the first dorsal interossei contracture not only can form tiger's jaw contracture, and still merge thumb metacarpophalangeal joints flexing and first finger metacarpophalangeal joints flexing.The Therapeutic Method of routine is to coordinate patient initiatively and passive functional exercise after operation, but can not within 24 hours, persevere, and curative effect is general.
After tiger's jaw damage or contracture deformity surgical repair, tiger's jaw need be fixed on functional position.Traditional Kirschner wire support tiger's jaw method effect is poor, and fixed effect is imprecise, is also unfavorable for initiatively and passive traction exercise; Postoperative for tiger's jaw Vessel Skin Flap, be also unfavorable for that flap is observed and processing in time.
Summary of the invention
The purpose of this utility model is to propose the anti-deformity of a kind of tiger's jaw to regulate orthosis.This structure is specially adapted to after tiger's jaw damage operation in patients fixing, and the early stage and reconvalescent's prestowage of wound, can effectively prevent and treat tiger's jaw contracture deformity.
The purpose of this utility model realizes by following technical proposals: it includes nut, screw rod, it is characterized in that: a screw rod has been threaded respectively on the female adjusting nut of both sides band, wherein a screw rod outer end is connected with fixed groove shape finger bracket, and another screw rod outer end is connected with and is rotated adjustable type groove shape finger bracket by an articulated structure work.
This utility model also comprises: for making the comfort of finger, be also provided with one deck soft layer in the inner side of groove shape finger bracket.
The adjusting nut of said structure and both sides screw rod are precession simultaneously or screw out structure.Its object is according to right-and-left threaded principle, can realize two threaded rods centripetal or outwards move in the time rotating adjusting nut, thereby adjusting grooves shape finger bracket distance adapts to the demand of thumb abduction.
Structure of the present utility model in use, the arc groove of two groove shape finger brackets is stuck on thumb and first finger, by swivel nut adjusting screw(rod) length, make two groove shape finger bracket stretching thumbs and first finger, regulate again the groove shape finger bracket angle of first finger end by articulated structure, when after first finger end groove shape finger bracket and first finger tight connecting, screwing screw, fixing.Be applicable to after tiger's jaw damage operation in patients fixingly, the early stage and reconvalescent's prestowage of wound, can effectively prevent and treat tiger's jaw contracture deformity.
The features such as this utility model also has simple and reasonable, easy and simple to handle, uses fast, and cost is low.
Brief description of the drawings
Fig. 1 is structural representation sketch of the present utility model;
Fig. 2 is the three-dimensional using state structure diagram of this utility model.
Below in conjunction with accompanying drawing and by example, this utility model is described in further detail; but following example is only this utility model example wherein; do not represent the rights protection scope that this utility model limits, rights protection scope of the present utility model is as the criterion with claims.
Detailed description of the invention
example 1
As shown in Figure 1, in figure 3 is the female adjusting nut of both sides band, a screw rod 2 and screw rod 4 have been threaded respectively in the both sides of the female adjusting nut of both sides band, be connected with fixed groove shape finger bracket 1 in the outer end of screw rod 2, and screw rod 4 outer ends are connected with rotation adjustable type groove shape finger bracket 7 by an articulated structure work; Described articulated structure comprises adjustable nut 5 and axle bed 6.Also be provided with the soft spongy layer 8 of one deck in the inner side of groove shape finger bracket, prevent that finger from having sense of discomfort.
The notch direction of the fixed groove shape finger bracket 1 of this structure and rotation adjustable type groove shape finger bracket 7 is outside, to adapt to the demand of thumb and first finger abduction.
The operation principle of this structure is: band spongy layer 8 grooves of first thumb being put into fixed groove shape finger bracket 1, then by rotating adjusting nut 3, make left side screw rod 2 for left-handed, right side screw rod 4 is dextrorotation, in the time rotating adjusting nut, can realize two screw rods 2 and screw rod 4 precession simultaneously or back-outs, thereby regulate the distance of fixed groove shape finger bracket 1 and the rotation adjustable type groove shape finger bracket 7 of both sides.Screw rod 4 outer ends in right side are designed to be fixed on and rotate adjustable type groove shape finger bracket 7 after fixed axis is connected with axle bed 6 by adjustable nut 5, realize the upper and lower angular adjustability of right side support bracket.After position adjustment simultaneously, screw adjustable nut 5, implementation structure entirety, steadiness, make the groove shape finger bracket kiss of the left and right sides join ground stretching between thumb and first finger, and tiger's jaw is fixed on functional position, and realizes the purpose of this utility model.
