Description

The radius far-end fracture strap.

This utility model relates to a kind of special-purpose clamping plate for the treatment of radius far-end fracture, belongs to the medical devices field.

Human radius far-end fracture is the highest fracture of incidence rate in the miscellaneous fracture, the frequently-occurring disease of elderly population traumatic injury especially.Work as radius far-end fracture, the fracture far-end is called the Ke Leishi fracture when dorsal part oar side is shifted; During the displacement of fracture far-end thenad side, be called smith's fracture.This treatment of fractures is not still had a kind of ideal clamping plate at present to fix.Treat the method for this fracture at present, first forearm splint, the far-end of forearm fracture clamping plate are at the carpal joint nearside, and effect is to lean against under the clamping plate of fracture to realize with the pressure pad compression fractures to fixation of fractures.In the time of compression fractures, the position of original fracture blood and lymph fluid backflow obstacle is oppressed more, made the matter worse, must be caused the fixed far-end limbs of clamping plate serious swelling.Loosen the blood circulation that the fixed band of clamping plate improves limbs for preventing the invalidity of limbs, often forcing, however clamping plate can't keep the fixation of fractures effect, the displacement once again that often causes fracturing or the malunion of fracture make that to hinder acropathy useless.It two is the inclined to one side clamping plate of palmar flexion chi, and this clamping plate can only be used for the Ke Leishi treatment of fractures.It is characterized in that the dorsal plate far-end has the one section long thenad lateroflexion of 2cm bent portions, the oar side plate is crossed the about 3cm of wrist, and is a straight plate.Because the palmar flexion section of dorsal plate far-end is too short, can not prevent effectively that the carpal back of the body from stretching activity, and oar side plate far-end is straight plate, uncertain to keeping the inclined to one side effect of wrist chi, and cause local compression, the final result of the similar forearm splint of its result.

The purpose of this utility model is the patient for numerous radius far-end fractures, develops a kind of treatment tool of rational in infrastructure, determined curative effect, i.e. the strap of radius far-end fracture.

Implementation of the present utility model is to be agent structure by A, B, C, D four block-shaped different form-fitting splints, press close to the limbs face and adhere to cushion, pack with knitting cloth outward, binding fixedly band and twice prevents the locking position band composition that clamping plate move, the shape that it is characterized in that A, B, C, four clamping plate of D respectively has characteristics, and fixed plastotype is arranged.The A plate is the palmar clamping plate when treatment Ke Leishi fracture, and is dorsal fitting splint when treatment offside Smith's fracture.The B plate is a dorsal fitting splint when treatment Ke Leishi fracture, is the palmar clamping plate when treatment offside Smith's fracture.The far-end of A, B two clamping plates all has a unidirectional sweep; The B plate is about 5cm than A plate; Bent about 60 degree of A plate far-end thenad lateroflexion, far-end reaches the head of metacarpal bone nearside and is about 2cm; B plate far-end is bent about 40 degree of thenad lateroflexion also, and about 30 degree of ulnad deflection, and far-end also reaches the about 2cm of head of metacarpal bone nearside.The width of A, B two clamping plate is near the width of forearm.The C plate is oar side clamping plate, far-end have one about 30 the degree with A, the equidirectional sweep of B two clamping plate, reach the about 2cm of first metacarpal bone head nearside; The D plate is the ulnar side clamping plate, and far-end has the sweep of long ulnad 30 degree of an about 3cm, and far-end also reaches the about 2cm of corresponding head of metacarpal bone nearside.A, B, four clamping plate of C, D are about 2/3rds of forearm length in the length of forearm section.Far-end is narrower than near-end, and the width of C, D plate is close with the thickness of forearm.Because the B plate distad slides easily, A, C, the easy proximad of three clamping plate of D slide, can not effectively keep carpal palmar flexion chi inclined to one side (when the treatment Ke Leishi fractures) back of the body with traditional binding mode and stretch the chi posture of (when treating Smith's fracture) partially, influence the fixation of clamping plate.For preventing clamping plate, the position that one negative and positive button locking position band locks four clamping plate is set respectively at the two ends of clamping plate easily to the slip of far and near direction and the displacement of side.One side of negative and positive button is separately fixed at the distance end outside of four clamping plate, and after four clamping plate were fixed on the limbs, the negative and positive that opposite side negative and positive button is sticked on the clamping plate were buckled again.The both sides of negative and positive button just closely are pasted together like this, make the locking position of four clamping plate, no longer are shifted, and have guaranteed the due fixation of clamping plate.For preventing the local compression of clamping plate to the apophysis position, paste one deck cushion at the limbs face of clamping plate, pack with knitting cloth the clamping plate outside, and clamping plate binding band uses traditional cloth band.

The good effect of present embodiment is to design a kind of novel strap for treatment of distal radial fracture.After displacement fracture is corrected, utilize soft tissue hinges such as periosteum and joint capsule to be tension band, keep the carpal joint palmar flexion position (when treatment Ke Leishi fractures) or the back of the body to stretch position (when the treatment Smith's fracture), and the chi off normal is made clamping plate and is fixed, meet the tension band fixation principle, the fracture after guaranteeing to reset no longer is shifted.Traditional in addition clamping plate are that pressured urgent pad is realized the partial compressing of fracturing to this fixation of fractures.This local compression be except that can causing the partial cutaneous necrosis of compressing to form the decubital ulcer, and it all causes the blood circulation of the limbs of stationary remote and lymphatic return and seriously influences, and is the one of the main reasons that causes the fracture fixation failure.Action principle of the present utility model changes local compression just and alleviates local compression for the larger area contact surface, utilize the tension band fixation principle, keep the carpal joint palmar flexion position (when treatment Ke Leishi fractures) or the back of the body to stretch position (when the treatment Smith's fracture), and the chi off normal is fixed, prevent the displacement again of fracturing, having created necessary conditions for the good healing of this fracture, is the whole new development of bone aspect this kind treatment of fractures of motherland's medical science traditional Chinese medical science.
