Abstract
The utility model discloses a shape memory alloy super-elastic limbs scar contracture deformity corrector which comprises a cladding layer and a shape memory alloy layer, wherein the shape memory alloy layer is fixedly installed inside the cladding layer. The shape memory alloy super-elastic limbs scar contracture deformity corrector can continuously and gently play a role in correcting damaged joints, and prevent and treat joint deformities. Moreover, the corrector has the advantages of high elasticity, comfortableness and convenience in wearing, good retentivity, less influence on independent activities, convenience in washing and the like.
Description
Technical field
This utility model relates to medical orthopedic instruments field, relates in particular to a kind of caused by scar that is used for causing behind extremities joint burn, the wound equivalent damage and prevents and apparatus for correcting.
Background technology
For major injuries such as burn, wounds, in tissue recovery process, can form cicatrix.Be positioned at the cicatrix at extremities joint (between for example shoulder, elbow, wrist, the palm refer to, refer to, knee joint, ankle, toe, sole of the foot toe etc.) position, tend to cause contracture deformity, give patient's extremity function and the grievous injury that brings attractive in appearance, greatly influence quality of life.Treatment to the extremity deformity of burned scar at present mainly comprises operation method and non-operative treatment; The operation method damage is big, need sacrifice other position normal structures sometimes and come correction deformity, nonetheless; The more slight deformity of correction section that also can only be limited, just powerless for deformity than severe.And miscellaneous non-operative treatment, its therapeutic effect is also undesirable.
Therefore, need provide a kind of super elastic shape memory alloy extremity caused by scar appliance to address the above problem.
The utility model content
In order to address this problem, the utility model discloses a kind of super elastic shape memory alloy extremity caused by scar appliance, said appliance comprises clad and shape memory alloy layer, it is inner that said shape memory alloy layer is fixedly installed on said clad.
Preferably, said shape memory alloy layer is set to the structure of grid.
Preferably, between the said appliance shoulder, elbow, wrist, the palm that are set to coat the patient refers to, refers to, knee joint, ankle, toe or metatarsophalangeal joints.
Preferably, also be provided with thread gluing on the said appliance.
The super elastic shape memory alloy extremity caused by scar appliance of this utility model can continue soft corrigent effect to be played in impaired joint, prevention and treatment joint deformity.And have high resiliency, wear comfortable convenience, retentivity is good, little to the autonomic activities influence, be convenient to characteristics such as washing.
In the utility model content part, introduced the notion of a series of reduced forms, this will further explain in specific embodiment part.This utility model content part does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection domain of attempting to confirm technical scheme required for protection.
Below in conjunction with accompanying drawing, specify the advantage and the characteristic of this utility model.

The specific embodiment
In the description hereinafter, provided a large amount of concrete details and this utility model has been understood more completely so that provide.Yet, it will be apparent to one skilled in the art that this utility model can need not one or more these details and be able to enforcement.In other example,, describe for technical characterictics more well known in the art for fear of obscuring with this utility model.
In order thoroughly to understand this utility model, detailed structure will be proposed in following description.Obviously, the execution of this utility model is not limited to the specific details that those skilled in the art has the knack of.The preferred embodiment of this utility model is described in detail as follows, yet except these were described in detail, this utility model can also have other embodiments.
Below with reference to accompanying drawing the embodiment of this utility model is made detailed description.
Referring to Fig. 1, be structural representation according to the super elastic shape memory alloy extremity caused by scar appliance 10 of an embodiment of this utility model.This appliance 10 comprises clad 11 and shape memory alloy layer 12, and shape memory alloy layer 12 is fixedly installed on the inside of clad 11.Can also be provided with thread gluing to regulate size on this appliance 10.
Above-mentioned shape memory alloy layer 12 is woven into grid or other shapes by the super elastic shape memory alloy silk material that the complex temperature is equal to or less than the body surface temperature.For marmem, after its shape is changed, in case when being heated to certain transition temperature, it can change back to original shape again.And super elastic shape memory alloy be meant rescuing of in the marmem deformation process, producing try hard to keep hold constant, forfeiture gradually with the recovery of shape.Marmem can provide in certain deformation range and continue the soft power of rescuing, and it is relevant to rescue the size of size and deformation of size and shape memorial alloy of power.Clad 11 is soft gas-pervious material.
This appliance 10 can be set to coat patient's extremity, comprise shoulder, elbow, wrist, the palm refer to, refer between, joint such as knee joint, ankle, toe, sole of the foot toe.With reference to figure 2-6, be the sketch map of correcting right elbow joint, right shoulder joint, right knee joint, right hand articulations digitorum manus and right crus of diaphragm toe joint according to the super elastic shape memory alloy extremity caused by scar appliance of an embodiment of this utility model respectively.
The super elastic shape memory alloy silk material that can select different qualities according to the stiff degree of the impaired joint injury degree of patient's extremity or cicatrix is to produce the corrective forces of different sizes.Cladding material needs properly parcel memorial alloy, and is soft ventilative, comfortable wearing, and contacting skin has no side effect.The cladding material shape can change with the change of memorial alloy shape.Can produce after the latticed marmem deformation and continue the soft power of rescuing; Can super elastic shape memory alloy extremity appliance be prefabricated into the shape of joint when unfolding during use; Hold with it and can keep the joint behind the impaired joint of extremity and be in extended position; The contracture power of opposing cicatrix, the prevention joint deformity.And to the patient of extremities joint contracture deformity is taken place, this appliance can produce and impel the joint to unfolding regressive soft restoring force, the correction deformity of continuing of posture.And the patient can initiatively overcome the deformation strength of latticed marmem easily and accomplish the activity in joint, can not influence autonomic movement during wearing.Simultaneously, patient's autonomic activities need overcome certain strength makes memorial alloy deformation, and this has played the effect of tempering the joint, helps the recovery as early as possible in impaired joint.
The super elastic shape memory alloy extremity caused by scar appliance of this utility model can continue soft corrigent effect to be played in impaired joint, prevention and treatment joint deformity.And have high resiliency, wear comfortable convenience, retentivity is good, little to the autonomic activities influence, be convenient to characteristics such as washing.
This utility model is illustrated through the foregoing description, but should be understood that, the foregoing description just is used for for example and illustrative purposes, but not is intended to this utility model is limited in the described scope of embodiments.It will be understood by those skilled in the art that in addition; This utility model is not limited to the foregoing description; Instruction according to this utility model can also be made more kinds of variants and modifications, and these variants and modifications all drop in this utility model scope required for protection.The protection domain of this utility model is defined by appended claims book and equivalent scope thereof.
