Abstract

The invention discloses a large vent structure fixing support prepared from a shape memory material through injection molding. A mixed raw material comprises polycaprolactone, a filler and auxiliary materials. In the large vent structure, a ratio of a hollow area to the total area is 7-70%. The large vent structure fixing support is provided with a removable and locking tightness adjustable locking connection device. Preferably, the large vent structure fixing support contains a coupling agent. The fixing support injection molding can realize stretching and curved surface deformation. The large vent structure fixing support has no coating. Through the large vent structure, the change of the illness can be directly observed and the complication after wound is prevented. The large vent structure fixing support can adjust a clamping tightness degree in the whole course of disease, can keep the soft tissue compression, has good fixing effects, is conducive to wound care after an operation,prevents reproduction according to a patient bodily form in use and can be simply operated by a doctor. The material does not suck water, has no liner structure, can be fast dried after a bath, is good in comfort, greatly improves the skin health status, prevents pruritus and dermatitis and can be used for outer fixation of upper limbs, neck, chest, waist and lower limbs.

Description

Technical field [0001] The invention relates to an adjustable external fixation brace, in particular to a general mesh plate used for making shape memory, belonging to the technical category of fracture external fixation. Background technique [0002] In the prior art, polycaprolactone is often used as an external fixation material for fractures. Due to the low melting point of polycaprolactone, the crystals melt near the melting point, resulting in a sharp drop in melt strength. During the softening process, it is highly viscous, similar to a mass of cement, and difficult to mold and process. Due to the above-mentioned characteristics of polycaprolactone, it is more difficult to manufacture products with complex structures such as fixed braces. In particular, it is difficult to use the injection molding process. In the prior art, the process of molding or calendering thermoplastic panels is usually used. After cutting, perforating, irradiating, spraying anti-adhesive coating an...
