Description
Technical field
It is specially a kind of to make materials for use in skull-fixing using 3D printing technique the present invention relates to increases material manufacturing technology field
Production method.
Background technique
When intracranial hypertension occur in craniocerebral trauma, cerebral hemorrhage, consistent both at home and abroad at present all to use decompressive craniectomy, purpose is just
It is that the brain tissue of swelling is allowed to have volume expansions to release stress, the skull of removal can also release certain space, to reach
It depressurizes purpose, but artificial causes " skull defeci ".
In the nearly traffic accident in 10 years in China, craniocerebral injury accounts for the 2nd in all kinds of wounds, incidence 22-
42%, about 600,000 person-times every year, it is more than dead 100,000 people；868.7 people of cranial vascular disease illness rate/100,000 populations, acute stage
The death rate has 50%, and skull defect repair material, which generallys use titanium net, at present (will do two-dimensional design, three-dimensional process, computer moulding
Deng), titanium poor biocompatibility, disadvantage is more, and now best materials for use in skull-fixing is PEEK material, but expensive.
After removing bone flap decompression operation, usually needs to carry out cranioplasty surgery again after 3-6 months, (need secondary cranium
Repairing bone operation), cranioplasty surgery traumatic larger and surgery cost is higher again again.
Summary of the invention
The purpose of the present invention is to provide the production methods using 3D printing technique production materials for use in skull-fixing, on solving
State the problem of proposing in background technique.
To achieve the above object, the invention provides the following technical scheme: a kind of make skull repairing using 3D printing technique
The production method of material, including cup body, elevating mechanism and resin storage tank, including following three steps；
Step 1: it is described before use, first obtain patient's skull CT images data, by professional software in computer carry out modeling and into
The processing such as row data modification, copies it in 3D printer to after processing, exposure module is according to set data to windowpane
Mouth emitting ultraviolet light, elevating mechanism is slowly slided upwards during irradiation, so that substrate is driven to be moved, substrate
The resin inside resin storage tank after being irradiated during movable by ultraviolet light is solidified in the bottom of substrate, without quilt
The resin that ultraviolet light is irradiated keeps the state of liquid, after printed, take out printing skull model and is manually cleaned, polished
Post-processing is cleaned printing skull model after processing, is sterilized, is packed；
Step 2: it is described patient's cranial bone flap is removed after, by simple process, be put into the inside of cup body, device connects power supply
The surface for pressing motor cabinet afterwards is provided with switch, motor shaft is fixedly installed at the top of motor cabinet, the surface of motor shaft is driven to fix
Blade is installed to be rotated, the cranial bone flap of patient is crushed to realize, and be ground into the particle of 1-2 square；
Step 3: the bone particle by crushing stirs evenly together with the blending of a certain proportion of biogum, after mixing evenly will
The bone particle that biogum mixes pours into printing skull model, after pouring into half, strikes off, at this point, placing supporting network ruling, puts
Remaining bone particle is poured into after good until arriving contour edge height, strikes off, molding bone particle bone flap is solidified after striking off,
Bone particle bone flap is taken out after solidification plants back patient's encephalic.
Further, the printing skull model is placed on sterilized space after the post-processings such as manually being cleaned, being polished
Inherence solidification 20-30 minutes.
Further, lid is fixedly installed at the top of the cup body, and the side of cup body is fixedly installed with handle.
Further, the operation consent printing skull model is carried out in normal room, and finished product will pass through strict sterilization, nothing
Bacterium bag dress, for use, whole process needs 60-90 minutes or so.
Further, step 2 with step 3 is carried out in operating room, and whole process all operates under aseptic conditions, operation
Time is about 15-20 minutes.
Compared with prior art, the beneficial effects of the present invention are: this utilizes 3D printing technique production materials for use in skull-fixing
Production method, when in use can be to the mistake that patient's cranial bone flap is crushed by being fixedly installed with lid at the top of cup body
Cheng Zhong avoids the broken body of patient's cranial bone flap from flying out from the inside of device, so that the practicability of device is improved, and by cup body
Side is fixedly installed with handle, can be more convenient user of service when in use and move to device, improve the practicability of device
With portability, and by with step 3 being carried out in operating room in step 2, whole process all operates under aseptic conditions, behaviour
It is about 15-20 minutes as the time, so as to avoid secondary cranioplasty surgery, reduces the wound of cranioplasty surgery again,
Surgery cost again has been saved, has driven the surface of motor shaft to be fixedly mounted by being fixedly installed with motor shaft at the top of motor cabinet
There is blade to be rotated, the cranial bone flap of patient is crushed to realize, by placing branch between printing skull model
Grid lines is supportted, can effectively increase the stability of printing skull model entirety, to keep device more secured.
