Description
The present invention relates to the form corrective therapy instrument of clubhand caused by clubhand particularly postburn hypertrophic scar contracture, category
In technical field of medical instruments, specially adjustable lopsided hand orthosis.
Background technology
Clawhand after burn orthodontic treatment is complicated, the course for the treatment of is long, and operative correction deformity does not recur thoroughly, easily.Operation is loosened scar
While trace, new scar generation is also easily caused；If have skin-grafting demand, the relaxation shrinkage of skin-grafting is up to 30-50%, and tendon, pass
Condyle, ligament, blood vessel, the contracture of nerve are difficult to effectively loosen by operation safety.There is scholar to quote warp for problem above
The Bone traction of allusion quotation is theoretical, and Bone traction technology is applied to the treatment of Repair of Claw Hand After Burn, obtains certain effect.
Existing market lacks ripe standardization traction appliance, during clinical treatment more use homemade Simple elastic brace,
Recover the elastic force of deformation after bending by medical Kirschner wire to provide continuous tractive effort, or the traction force that other elastomeric materials are provided
Correction deformity position.Although these traction appliances can obtain certain therapeutic effect, the personal experience of doctor is limited to, it is unsuitable
Popularity, treatment cycle is very long in addition, and selected elastomeric material is inevitably plastically deformed, and key parameter certainly will occur
Drift, influences therapeutic effect；And brace build process is random, be contrary to the spirit of accurate medical treatment.
The content of the invention
Present invention seek to address that at present clinical treatment when the problem of lack ripe, clubhand's traction appliance of specification there is provided
A kind of adjustable lopsided hand orthosis, treatment parameter can be adjusted at any time over the course for the treatment of（Size and direction such as tractive force）,
It is that clinical procedure treatment and scientific research provide basic data.
The present invention adopts the following technical scheme that realization：Adjustable lopsided hand orthosis, including one end are vertically embedded in
Some Kirschner wires of metacarpal bone, to be fixed on the arch or semicircle support chip of each Kirschner wire other end, one end perpendicular to the back of the hand state
Pass through and be fixed on support chip, the other end is extended above finger and parallel to the hollow support rails of the back of the hand, is fixed on support chip
The back side（Towards the one side of wrist）Check hinge line device；Also include bracing wire, one end of bracing wire through hollow support rails and fixation, twine
Be around in check hinge line device on, the other end concatenation pulling force sensor or spring scale after is connected with hook or fingertip, hook with it is embedding
In the connector in finger tip（Such as Kirschner wire）Hook connects, or is directly connected in finger tip by fingertip.In use, by rotating check
The tension force that line device can adjust bracing wire is cut with scissors, the regulation to finger tip tractive force is realized；Pulling force sensor（It is other well known by what is configured
The display device being connected with pulling force sensor）Or spring scale scale shows tractive force size, so as to reach tractive force precise quantification
Purpose.Wherein check hinge line device is using existing known various structures.
Described hollow support rails are by anterior hollow fix bar, hollow middle portion adjusting rod and hollow rear portion adjusting rod structure
Into one end of anterior hollow fix bar passes through and is fixed on support chip, and one end vertical direction of hollow middle portion adjusting rod can
Adjust ground to be hinged and fasten with the hollow fix bar other end, one end horizontal direction of hollow rear portion adjusting rod adjustably with hollow middle portion
The other end of adjusting rod is hinged and fastened；In this way, hollow middle portion adjusting rod realizes the regulation of pulling force vertical direction, hollow rear portion is adjusted
Pole realizes the regulation in tension level direction.Or, described hollow support rails are adjusted by anterior hollow fix bar, hollow middle portion
Pole and hollow rear portion adjusting rod are constituted, and one end of anterior hollow fix bar passes through and is fixed on support chip, hollow middle portion
One end horizontal direction of adjusting rod is adjustably hinged and fastened with the hollow fix bar other end, and one end of hollow rear portion adjusting rod is erected
Nogata is to being adjustably hinged and fasten with the other end of hollow middle portion adjusting rod；In this way, hollow middle portion adjusting rod realizes pulling force water
Square to regulation, hollow rear portion adjusting rod realizes the regulation of pulling force vertical direction.
The present invention is theoretical there is provided continuing and any adjustable traction force based on tissue retraction, promote distortion site by
Step is recovered or close to normal morphology, to reach therapeutic purposes.Traction force numerical value that the present invention is produced, direction stablize adjustable.With class
Being compared like existing like product, Stability Analysis of Structures is controllable, data reliable, can provide exact numerical for successive treatment and clinical research
Precise information is provided.
