Description
Technical field
The invention belongs to correct class medical instruments field, stablize especially for after neck injuries or after cervical operation
A kind of correction class medical instruments field, and in particular to for a kind of 3D printing individuation neck brace and preparation method thereof.
Background technique
A kind of Medical treatment device that neck brace uses when being neck injuries, the postoperative fixation of cervical vertebra or auxiliary treatment of cervical spondylosis
Tool can play braking and protection neck, reduce the abrasion of nerve, mitigate articuli intervertebrales traumatic reaction, and be conducive to tissue water
Swollen recession and the effect consolidated curative effect, prevent recurrence.Neck brace can be applied to each myelopathy and neck injury, to acute attack
Phase patient is especially more suitable for the patient of herniation of cervical disc, adrenergic type and vertebral artery type of cervical spondylosis.
Existing neck brace does not have a design of individuation, (such as large, medium and small) self by patient of only seldom model
The needs to realize different patients are adjusted, but it is often improper to the short and thick patient of some necks, do not have fixed, maintenance life
Manage the curative effect of lordosis and post surgery stabilization.Furthermore the design of neck brace is mostly closed at present, and material is mostly plastics, latex etc.,
Often because airtight comfort level when patient being caused to use is low.
As 3D printing technique is in the development of medical domain, start to occur simultaneously for the individualized treatment instrument of patient itself
Start to be widely applied, the therapeutic device of individuation is because being directed to sufferers themselves, and when use installs easy to operate, and property of coincideing is very high, suffers from
Comfort level is high when person uses.3D printing technique is applied to the individuation preparation of neck brace, is bound to play good technology
Effect.
The purpose of the present invention is not strong for existing neck brace individuation, stability is poor, the technical problems such as comfort difference, benefit
A kind of individuation neck brace for patient oneself is prepared with 3D printing technique and preparation method is provided.
Summary of the invention
In order to overcome the neck brace individuation of the prior art not strong, stability is poor, the technical problems such as comfort difference, of the invention
Purpose is to provide a kind of 3D printing individuation neck brace and preparation method thereof that can solve the above problem.
The purpose of the present invention is achieved through the following technical solutions:
A kind of preparation method of 3D printing individuation neck brace, specifically includes the following steps:
1) the individuation data of patient's skin of neck are obtained in such a way that 3D is scanned；
2) neck brace is reversely fitted and designed to scan data, by whole neck brace segmentation of structures at several piece piecemeal knot
Structure, and each partitioned organization is numbered, and fixinig plate combined hole is designed on each partitioned organization, and corresponding design fixinig plate,
Setting fixinig plate is followed closely thereon, is used in conjunction with fixinig plate combined hole；In addition buckle is designed between two partitioned organizations wherein；
3) design data is imported in 3D printer and prints each partitioned organization and fixinig plate；
4) each partitioned organization printed is combined assembly using sticker and elastic ribbon, and is set in more flat place
Buckle structure (4) are set, for being combined to each partitioned organization (1).
Further, the scanning mode can be the scanning mode of any available somatic data, wherein it is preferred that the doctor used
Learning image capture device is that Creaform HandySCAN 700 holds three-dimensional laser scanner or the Portable laser of other models
Scanner etc..
Further, the scanned position of neck brace individuation scan data is that upper forepart is scanned to lower jaw, can hold lower jaw,
Lower front scanning is extended at breastbone at clavicle, and upper rear portion is scanned to occiput, and lower rear portion, which is scanned to neck chest, to have a common boundary
At acromioclavicular joint.
Further, when scanning, under surgical state, patient, which is in, to be gone directly to be scanned when pillow supine position, and scanning obtains
State when cervical vertebrae physiological lordosis.Under No operation state, it is desirable that state when patients with cervical is in physiology lordosis (i.e. head face upward to
The line of the corners of the mouth and ear-lobe is perpendicular to the ground, and nose is in a straight line with navel) it is scanned, to obtain optimal scanning effect,
The reversed fitting neck brace that such state obtains can preferably treat patient.
Further, neck image data scanning obtained import the included data acquisition software of scanner, establish human body
The threedimensional model of neck；Neck threedimensional model is input in 3D printing system with STL format, generates motion profile code；
