Abstract
A post craniocerebral operation once shaping artificial bone flap belongs to manufacturing technical field of medical apparatus, adopting a bone flap body matching with the calvaria bone; the bone flap body is thick in the center and becomes thinner to the around edge gradually. The bone flap body is provided with at least a connecting hole. The bone flap body is formed by heat press shaping of hydroxy propyl cellulose, methyl silicone rubber, magnesium stearate, medical talc powder, acrylic resin, polyethylene 2000F, human bone powder glue fat, arabic gum, and curing agent. The utility model has high mechanical intensity, stable performance, flexible performance, and no corrosion and degeneration for long term use; the artificial bone flap can be floated with the bulged edema brain tissue to reduce the pressure sufficiently, when the edema of the brain tissue aggravates gradually after the operation; the artificial bone flap can return to normal to reduce the pressure automatically, when the edema disappears, thereby guaranteeing the patient living through the peak period of the hydrocephalus placidly.
Description
Technical field:
This utility model belongs to medical apparatus manufacturing technology field, is a kind of cranium brain artificial bone flap.
Background technology:
Behind the neurocranial surgery exenterate bone lobe, edema appears in patient's cranium brain, and present technological means is to carry out the secondary forming operation after edema is eliminated, replant the bone lobe of making into silica gel or bone cement, patient's operative treatment time of being in hospital is long, body and all very painful mentally, and medical expense is also bigger.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of once forming artificial bone flap used after craniocerebral operation.
Technical scheme of dealing with problems of the present utility model is to adopt the bone lobe main body that matches with cranium to make, and bone lobe main body thick middle to edge attenuation gradually, has a connecting hole at least on bone lobe main body.
For bone lobe main body is fixed on the skull more easily, have fixing hole at the edge of bone lobe main body.
Bone lobe main body is made by following component material: (consumption is a ratio of weight and number)
Acrylic resin 40-60 polyethylene 2000F 23-28
Hydroxypropyl cellulose 0.5-1.5 methyl silicone rubber 1-2
Skeleton resin 10-20 arabic gum 5-10
Firming agent 1-5 medical talc powder 0.3-0.8
Magnesium stearate 0.5-1.5
This utility model manufacture method is as follows:
To send into the comminutor pelletize after hydroxypropyl cellulose, methyl silicone rubber, magnesium stearate and the medical talc powder mixing; mix with acrylic resin, polyethylene 2000F, skeleton resin, arabic gum and firming agent then; send into extruder again; under 260-280 ℃ of temperature conditions, extrude synthetic former material; former material is sent in the hydro-forming machine mould, and hot forming is made the artificial bone lobe of the present invention under 60-80 ℃ of temperature conditions.
Artificial bone flap of the present utility model is used for clinical after zoopery, in 18 examples of clinical practice, acute subdural hematoma 7 examples, and cerebral hernia 2 examples, acute epidural hematoma 4 examples, large tracts of land sunken skull comminuted fracture 1 example, hypertensive cerebral hemorrhage 4 examples, no death, postoperative 10-15 days in the otch top and each row one 1.5CM of place otch of both sides, with staple bone fixation lobe, do not find rejection after the 16 example operations of this group, there is not hematocele hydrops under infection and the scalp, a small amount of hematocele under the 2 routine scalps, tracing observation three months to 2 years, patient's head good looking appearance, the fixation of bone lobe, there is not uncomfortable symptom, the pressure that is a cup too low, the check Cranial Computed Tomography is not all found hydrops under the bone lobe.
This utility model mechanical strength height, stable performance has certain flexibility, and life-time service does not corrode, invariance, when the postoperative cerebral edema increases the weight of gradually, can float with the bulging of edema cerebral tissue, decompression is fully, after cerebral edema disappears, artificial bone flap can automatically reset, and plays automatic decompressing effect, and it's the pinnacle of cerebral edema phase is past assurance patient smoothness.After treating that edema disappearance cranium positive pressure is normal, with incision of scalp, with staple artificial bone flap is fixed on the skull, sews up the incision, the postoperative intracranial tissue can link together by connecting hole and scalp tissue growth.
Description of drawings:
Fig. 1 is this utility model sketch map;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
Get hydroxypropyl cellulose 1 gram; methyl silicone rubber 1.5 grams; after mixing, magnesium stearate 1 gram and medical talc powder 0.6 send into the comminutor pelletize; then with acrylic resin 50 grams; polyethylene 2000F25 gram; skeleton resin 15 grams; arabic gum 7 grams and firming agent 3 grams mix; send into extruder again; under 270 ℃ of temperature conditions, extrude synthetic former material; former material is sent in the hydro-forming machine mould; hot forming is made bone lobe main body 1 under 70 ℃ of temperature conditions; bone lobe main body 1 thick middle; to edge attenuation gradually; have ten connecting holes 2 on bone lobe main body 1 at least, the edge of bone lobe main body 1 has fixing hole 3 equably.Through packing, the ethylene oxide sterilizing sterilization gets final product.
Claims (2)
1, a kind of once forming artificial bone flap used after craniocerebral operation is characterized in that: comprise bone lobe main body, bone lobe main body and cranium match, and bone lobe main body thick middle to edge attenuation gradually, has a connecting hole at least on bone lobe main body.
2, artificial bone flap according to claim 1 is characterized in that: the edge of bone lobe main body has fixing hole.
