Description
Technical field
The present invention relates to medical instruments field, specially a kind of low temperature thermoplastic rehabilitation brace and preparation method thereof.
Background technique
Skeleton is one of movable most, physical feeling that movement is most complicated in daily life, also most vulnerable
One of position, meanwhile, with advancing age, neck, waist will appear a series of retrogression pathological changes.Correspondingly, clinically locating
Manage various fracture, the support and fixation that orthopaedics is postoperative and retrogression pathological changes, inflammation, pain are orthopedic, material used at present is main
There are plaster bandage, polymer bandage, low temperature brace, high temperature orthoses, woodwork and metal or plastics system and not castable clamp, with
Reach stablize support, it is fixed with it is orthopedic and exempt from load, it is compensatory acted on protection and power-assisted, these materials all respectively have excellent, disadvantage.
Due to will appear inflammation, oedema, pain after limb injury, the prolonged fixed muscle adhesion that will cause causes limbs stiff
Firmly, plaster bandage, polymer bandage need electric saw skin easy to cut when wearing disassembly；It is airtight, hardness is high, liner and suitable
With compressibility ulcer can not caused at that time；High temperature orthoses fabrication cycle is long, and patient cannot wear influence treatment in time；And brace
Bandage cannot often coincide very well with limbs fastening, be easy to scratch skin, be easy to loosen.
Low-temp thermoplastic material is a kind of high molecular material, it is characterized in that can soften at a lower temperature and be moulded into arbitrary shape
Shape, thus medical domain can be applied to.Soften at low temperature since low-temp thermoplastic material has, plasticity is strong, has memory
Function, light weight, have certain intensity, be easy to be bonded, X-ray permeability is good, can multiple thermoplastics type, can reuse,
The advantages that doctor is easy to operate, can be biodegradable after discarding has been used for Orthopeadic Surgery at present and fixes, radiotherapy positioning, makes
Orthopedic brace and rehabilitation brace etc..However, the bone feature due to everyone is different, if to be accurately positioned, accurately prop up at present
Support, then have to make to measure.Although existing polycaprolactone product forming is convenient, the rigidity after forming is not strong, causes solid
Fixed fastness is inadequate, and shrinking percentage is larger, and product on the market is ventilative also general, uncomfortable so as to cause patient.Therefore, low
Warm moulding material still needs to constantly improve.

Further, brace ontology integral outer ring's contour structure is tangent-type shape.
Further, the bandage of the fastening structure is elastic force cotton stockinette.
Further, the fastening structure has small hook and tight lock.
Further, the fastening structure bracket is elastic material.
A kind of production method of low temperature thermoplastic rehabilitation brace, comprising the following steps:
(a), user's hand body surface data are scanned；
(b), according to user's hand body surface data, integral outer ring's contour structure of brace ontology is set；
(c), the ulna open circles hole site at thumb position and wrist two is set；
(d), the size of the hollow circular hole of ulna at the flexible gasket size structure in thumb position and wrist two is adjusted.
(e), fastening structure position distribution is arranged according to integral outer ring's contour structure of brace ontology；
(f), 80 parts of polycaprolactone of thermoplasticity memory-type material are taken, 20 parts of polylactic acid, is carried out using in double screw extruder
Extruding pelletization, then the injection molding in injection molding machine obtain designed brace ontology.
(g), product is impregnated five minutes in 80 DEG C or so hot water, after taking out, dries surface, by reverse side towards palm
The heart, thumb pass through hole site, wrist ulna position alignment, then with whole arm, the centre of the palm fitting, with clamp device 2 fasten, i.e., it is whole
A brace fixation finishes.Whole operation process succinctly facilitates, and is suitable for various environment.
The present invention and is cooperated by based on being engaged in such product design manufacture practical experience and professional knowledge abundant for many years
The utilization of scientific principle, is actively subject to research and innovation, to found a kind of light-weighted thermoplasticity memory-type three-dimensional porous structure and phase
The preparation process answered, make the low temperature thermoplastic rehabilitation brace is lighter, gas permeability more preferably, intensity it is higher.By constantly studying, setting
Meter, and after studying sample repeatedly and improving, the product having practical value is created finally.
