Abstract
This utility model discloses a kind of hammer finger deformity corrector, it comprises the fixing holder of the last dactylus being respectively used to fixing last dactylus and middle finger joint and middle finger joint fixes holder and fixing band, the fixing holder of described last dactylus is connected by self-locking rotating shaft with the fixing holder of middle finger joint, described last dactylus is fixed holder and middle finger joint and is fixed angle α between holder and can regulate locking by self-locking rotating shaft, and described middle finger joint is fixed holder and last dactylus and fixed and ask the upper surface of base body to match with middle finger joint and last dactylus palm of the hand direction surface configuration successively respectively.The hammer finger deformity corrector structure of this utility model design is simple, and easy to use, treatment cost is low, and therapeutic effect is remarkable.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of hammer finger deformity corrector.
Background technology
Hammer finger is gained the name because of the shape of deformity of dactyl, and namely ungual phalanx of fingers can not initiatively stretch, and in apron deformity, nearside finger-joint slightly upwarps.When the tendon rupture of phalangette base portion, hammer finger can be caused.Suffer extraneous drag when digital tip and bends occurs, during as fallen, finger stretches and contacts to earth, or when Distal phalanx is injured by a crashing object and is stretched suddenly finger with hard object collision etc., all can cause point dorsiflexion tendon stop damage, tear or rupture completely.Severe patient can merge avulsion fracture, the symptom caused and deformity heavier.
The method of hammer finger is treated for be fixed by injured dactylus by planter cast or Absorbable rod holdfast in prior art, fixing means is appropriate negative drawing, namely last dactylus is fixing towards the opposite direction stretching of palm, over the course for the treatment of injured dactylus is stretched after fixing 4 ~ 6 weeks in the other direction, in order to stable therapeutic effect need injured finger to set level after fix about 4 weeks again.But it is very inconvenient that planter cast carries out needing when setting level fixing that original Gypsum Fibrosum is removed planter cast again after oppositely being fixed by injured finger again.Although adopt Absorbable rod holdfast to fix injured dactylus therapeutic effect pretty good to need to carry out to hole or the surgical operation such as otch, increase patient suffering, wound infection risk and treatment cost.Therefore need to relate to a kind of medical apparatus and instruments being used for the treatment of dorsiflexion tendon stop fracture merging lacerative fracture newly.
Utility model content
The purpose of this utility model is to provide a kind of hammer finger deformity corrector.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of hammer finger deformity corrector, it comprises the fixing holder of the last dactylus being respectively used to fixing last dactylus and middle finger joint and middle finger joint fixes holder and fixing band, the fixing holder of described last dactylus is connected by self-locking rotating shaft with the fixing holder of middle finger joint, described last dactylus is fixed holder and middle finger joint and is fixed angle α between holder and can regulate locking by self-locking rotating shaft, and described middle finger joint is fixed holder and last dactylus and fixed and ask the upper surface of base body to match with middle finger joint and last dactylus palm of the hand direction surface configuration successively respectively.
As a kind of optimal technical scheme, described last dactylus fixes holder and the middle finger joint angle α fixed between holder is 0 ~ 30 °.Further preferred described last dactylus fixes holder and the middle finger joint angle α fixed between holder is 0 ° or 30 °.
As a kind of optimal technical scheme, the other end that described middle finger joint fixes holder is connected with the fixing holder of nearly dactylus.Described nearly dactylus is fixed and is ask the upper surface of base body and nearly dactylus palm of the hand direction surface configuration to match.
As a kind of optimal technical scheme, described self-locking rotating shaft comprises rotating shaft and is sleeved on the axle sleeve outside rotating shaft, described rotating shaft connects the fixing holder of middle finger joint, described axle sleeve connects the fixing holder of last dactylus, described rotating shaft is provided with at least one locating slot, described axle sleeve is provided with guide, is provided with the alignment pin of end belt draw ring in described guide.The anglec of rotation with adjustment in use locking rotating shaft joined by described locating slot, guide and alignment pin, and then regulates the described last dactylus of locking to fix holder and middle finger joint fixes the angle of the angle α between holder.
During use, last dactylus is fixed holder, middle finger joint fixes holder and nearly dactylus is fixed care set and is located on injured finger and fixes with fixing band, the angle of angle α that holder and middle finger joint fix between holder locks to regulate last dactylus to fix, last dactylus is fixing towards the opposite direction stretching of palm, over the course for the treatment of injured dactylus is stretched after fixing 4 ~ 6 weeks in the other direction, in order to stable therapeutic effect, extract alignment pin, regulate last dactylus fix holder and the middle finger joint angle α fixed between holder be 0 °, fix about 4 weeks again after being set level by injured finger.
The beneficial effects of the utility model:
The hammer finger deformity corrector structure of this utility model design is simple, and easy to use, treatment cost is low, and therapeutic effect is remarkable.
