Abstract

The utility model relates to an artificial limb for an amputated lower leg, comprising an AAS plastic board 1, a bolt 2 and a resin bandage 3. The advantage that the AAS plastic board becomes soft and can be molded when the temperature is less than 100 DEG C is used to avoid that the prior artificial limb shell can only be molded after melted with high temperature. The resin bandage has good molding and felting characteristics after dipped in hot water, which can be used to enwrap the artificial limb and solve the problems of conglutination and fixing, leaving out a plurality of equipments and procedures. Therefore, the manufacture of the artificial limb has the advantages of easy operation, simple equipment, accessible material and easily learned method.

Description

Simple and easy practical artifucial limb

(1) technical field: this utility model relates to a kind of below knee amputation postoperative, to the artifucial limb of deformed limb installation.It is the artifucial limb of making as shell with AAS plastic plate (1).

(2) background technology: at present, generally leg stump is installed artifucial limb, the plastics of its shell generally all need high temperature melting to become to be cast on the mould behind the liquid to form, and then machine through working procedures.Because equipment and complex procedures, thereby can only just can finish at artificial limb factory of certain scale.And must many times.

(3) summary of the invention: purpose of the present invention is exactly when making the cabinet artifucial limb, provide a kind of can not must high temperature melting, and need only low-temperature heat just can molding scheme.This utility model is realized by following mode:

Manufactured materials is by (1) common gypsum binder (2) resin binder ^[2](3) compositions such as AAS plastic plate (6) ankle socks liner of Luo silk (5) the 3mm thickness of the long 20cm--30cm φ of Gypsum Fibrosum powder (4) 16ccm.Wherein utilize the plasticity behind the plaster bandage water breakthrough, fast deformed limb is carried out modeling (die).Utilize behind the Gypsum Fibrosum powder water breakthrough fast the characteristics of hardening perfusion die to produce punch (just as deformed limb).Utilize easily moulding characteristics behind the AAS plastic plate cushioning again, produce artifucial limb around punch.Can become very soft after utilizing the resin binder in water temperature more than 70 ℃, to soak at last, but have tough and tensile characteristics after the cooling, hold the artifucial limb shell it is fixedly secured.

(4) description of drawings: this utility model is further described below in conjunction with accompanying drawing:

Fig. 1 is the AAS plastic plate sketch map that cuts.

Fig. 2 is the screw sketch map.

Fig. 3 is a resin binder sketch map.

Fig. 4 is for assembling the sketch map of the artifucial limb of finishing.

1 is the AAS plastic plate in the accompanying drawings, and 2 is the screw of φ 16mm, and 3 is the resin binder.

(5) specific embodiment: at first twine leg stump to the modeling of patella lower edge with plaster bandage, take advantage of Gypsum Fibrosum approximately after half an hour and mould is not taken off when dried, this is the deformed limb die.Stir into pasty state with Gypsum Fibrosum powder and water then, be poured in and produce punch replacement deformed limb on this mould, multiple ankle socks liner on this die sleeve.The AAS plastic plate that again will be in advance cuts by the punch shape is wrapped on the punch after the heating deliquescing, and outside reuse resin binder is fastened firmly.In its bottom hole, mix the Luo silk of choosing length φ 16mm after the cooling hardening, artificial limb is promptly accused and is finished.

AAS plastics full name is that propylene is fine--acrylate--styrene polymer. Be little yellow; Can Painted, have good environmental stress crack resistance, can bear for a long time in a lot of application scenarios Quiet or moving load, indeformable in 100 ℃, have good antistatic behaviour, that gathers is quiet The very fast release of charge energy. But organic solvent-resistant not. Sheet material can carry out the vacuum rapid shaping and not have and answer Force deformation. The sheet forming heating-up temperature can be at 80 ℃～90 ℃. Typing after the cooling. Be adapted to make Watchcase, safety helmet, casing, furniture etc., outdoor storing 2 years still flexible constantly, the gasproof marquis Performance is good. [2] the resin bandage is beautiful pearl board, is produced by the beautiful pearl in Zhuhai group. Be applied at present the wound bone more Section, it is mesh-shape, matter is hard, tough and tensile. Stiffness is good, becomes after soaking in water temperature more than 70 ℃ Must be very soft, and have good viscosity, namely bonding is firm after moulding winding, again not Can take apart.

Claims

1, a kind of artifucial limb of being made up of AAS plastic plate (1), screw (2) and resin binder (3) is characterized in that shell is the artifucial limb of being made by the AAS plastic plate.

2, according to the described artifucial limb of claim 1, it is characterized in that the artifucial limb shell formed by the AAS plastic plate, the fixedly usefulness of its outside be the resin binder.
