Description

A kind of bone injury external fixation Chinese medicine plastic material

The invention belongs to a kind of clinical medical material, exactly is a kind of bone injury external fixation Chinese medicine plastic material.

Bone healing must be fixed.Be fixed with two kinds of internal fixation and external fixation, the latter is clinical the most commonly used.External fixation generally adopts Gypsum Fibrosum and clamping plate at present both at home and abroad.Gypsum Fibrosum plasticity is good, but can only use once, and after the detumescence of bone injury position, it is fixing solid inadequately firm; The activity of clamping plate convenient fixing limbs, also solid firm, but effective inadequately to fracture near the juxtra-articular position, because clamping plate are difficult to be processed into the corresponding physiology shape in this joint.CN85100278 discloses a kind of thermoplasticity splint material, is mixed through hot pressing, plasticizing, cooling processing by a certain percentage by vinyl chloride-vinyl acetate resin, MBS or ABS resin and plasticizer, stabilizing agent, coloring agent, has plasticity; CN2079491U discloses a kind of medicine splint, is made up of restraint zone, inside and outside laminate, contains Chinese medicine ingredients in the inner plating; CN87101407 discloses a kind of moulding material clamping plate, is formed by polyisoprene or the mixing pressure of prolonging of natural rubber, additive Pulvis Talci or white carbon, calcium sulfate, silicon dioxide and stearic acid.Foreign literature is not seen as yet by retrieval and is contained Chinese medicine plasticity external fixation material.

The purpose of this invention is to provide a kind of new clinical external fixation material, this material has plasticity, can be according to the physiology shape of bone injury limbs correspondingly mouldingly make it to clad in appearance skin, the cooling after fixing forms one with limbs, fixedly consolidation is reliable, and Chinese medicine ingredients wherein helps channels and collaterals persuasion, blood circulation promoting and blood stasis dispelling, reducing swelling and alleviating pain, prevention dermatitis etc. to heighten the effect of a treatment.

The present invention is formed by impression compound, Chinese medicine powder, modifier and reinforcement uniform mixing.The percentage by weight of four kinds of components is:

Impression compound: 50～80%

Chinese medicine powder: 10～40%

Modifier: 2～8%

Reinforcement: 5～10%

Described impression compound plays the molding fixation, it is one of department of stomatology modeling material commonly used, softening when meeting heat (70 ℃), solidify under the room temperature, but repeatedly use back viscosity and plasticity to reduce repeatedly and (see " dental prevention " the 440th, odontopathy center, Shanghai dispensary compiles in June, 1987 and publishes), its transplanting is used for the bone injury external fixation need adds modifier.

Described modifier is vaseline or glycerol or other fatty acid esters, as dodecanoate, oleate, linoleate, stearate etc., can use separately, also can composite each other use, and compound proportion is any.In above-mentioned modifier with vaseline and glycerol for well.

Described Chinese medicine powder is to grind, smash into smalls after thirty Six-element Chinese medicine mixes at most with selected at least eight flavors, or grinds, smashes into mix homogeneously behind the smalls respectively, and it is stand-by to put shady and cool dry place.Since be outer application, thus not tight to the dosage collocation requirement of each flavor, respectively get basic equivalent and get final product.Fineness also do not required sieves that it is better to sieve certainly.Eight flavor Chinese medicines are that the Radix Aucklandiae, Cortex Cinnamomi, the Radix Angelicae Dahuricae, Rhizoma Chuanxiong, Rhizoma Curcumae Longae, Rhizoma Arisaematis, Borneolum Syntheticum, Indigo Naturalis are respectively got equivalent, grind, to smash into smalls stand-by.Thirty Six-element Chinese medicine is: Olibanum, Myrrha, Sanguis Draxonis, Rhizoma Et Radix Notopterygii, the Radix Aucklandiae, Cortex Magnoliae Officinalis, Radix Aconiti, Radix Aconiti Kusnezoffii, the Radix Angelicae Dahuricae, Rhizoma Cyperi, Fructus Foeniculi, Cortex cercis chinensis, Fructus Chaenomelis, Cortex Cinnamomi, Radix Angelicae Sinensis, Radix Angelicae Pubescentis, Radix Dipsaci, Rhizoma Chuanxiong, Cortex Phellodendri, Rhizoma Curcumae Longae, Radix Et Rhizoma Rhei, Rhizoma Atractylodis, Pericarpium Citri Reticulatae, Herba speranskiae tuberculatae, Radix Glycyrrhizae, Rhizoma Drynariae, Jing Jie, Radix Saposhnikoviae, Fructus Gleditsia, Ramulus Sambuci Williamsii, Flos Carthami, Radix Paeoniae Rubra, Herba Menthae, Borneolum Syntheticum, Indigo Naturalis, Rhizoma Arisaematis, get respectively that equivalent is ground, to smash into smalls stand-by.

Described reinforcement is cellosilk or net, also tinsel or net.It can be synthetic fibres or net that cellosilk becomes net, as polrvinyl chloride, polyethylene, polyacrylonitrile, polypropylene, polyester, polyamide etc., also can be artificial cellosilk or net, as viscose rayon, acetate fiber etc.Tinsel such as stainless steel silk etc. can use, but price is more expensive.Each veriety of synthetic fibers and staple fibre can use separately, and use also can be mixed with each other.

Above-mentioned four kinds of blended courses of processing of component, its main points are to be uniformly dispersed.

Impression compound and modifier are put into container in baking oven (70～100 ℃) fusings (A) (if modifier then needn't melt with impression compound as glycerol etc. together for liquid) that heat up, drop into the cellosilk of Chinese medicine powder and 3～4 centimeter length behind the taking-up A, (C) stirs, C promptly is the plastic material that contains Chinese medicine, have solidified characteristics under the thermal softening of being subjected to, the room temperature, and can use repeatedly.Be convenient clinical use, C should be put on the flat board that is covered with wet cloth and prolong plate-like (D) that is pressed into 4～6 millimeters thick, according to the needs of external fixation different parts consumption with D be cut into the different length of different size-be and width-platelet, treat that platelet solidifies back parcel one deck looped fabric and puts into plastic bag and seal for clinical and take at any time.Because this material is promptly curable at ambient temperature, so the operation of taking out behind the A must be rapidly.

If cellosilk is long or netted, the effect of reinforcement is played in following operation equally.Drop into Chinese medicine powder after taking out A, stir (B) is put into B on the flat board that is covered with wet cloth and prolongs pressure, discharges fiber or net then in an orderly manner, prolongs and presses one deck B, prolongs plate-like (D) that be pressed into 4～6 millimeters thick at last, contains one deck reinforcement among the D at least.The later processing of D is the same.

Four kinds of components must mix homogeneously in a word, and wherein reinforcement can be unordered homodisperse, also can be orderly uniform distribution.

Be the ventilation of favourable fixed position, can on the platelet of molding, process several eyelets.

The present invention has moulding, the elasticity and the intensity of Gypsum Fibrosum and wooden splint concurrently, it meets the characteristics of thermal softening, cold curing, not only can use repeatedly, especially be fit near the fixation of fractures of elbow joint, bent degree because should fixing will regularly change stretching of elbow joint usually, use the present invention does not need to change new material, it is softening only to need to heat up, can change the situation in the wrong of stretching, solidify then, all very convenient to doctor and patient.The present invention simultaneously has the external application for curing effect, but dredging the meridian, blood circulation promoting and blood stasis dispelling, anti-inflammatory analgetic, prevention dermatitis, in order to the wound early recovery.Raw material of the present invention is easy to get, and each component is all nontoxic, and is safe in utilization, handling ease, and cost is also low, the new material that a kind of bone injury external fixation of can yet be regarded as is used.
