Embodiment
The reality of casting and preparation method thereof is substituted to the 3D printing of traditional orthopaedics gypsum of the present invention below with reference to accompanying drawing
Existing process is illustrated.
As illustrated in fig. 1 and 2, a kind of 3D printing of traditional orthopaedics gypsum substitutes casting, by upper piece casting (1) and bottom sheet casting
(2) constitute, wherein, upper piece casting (1) is respectively arranged on the left side and the right side several grooves (3)；The bottom sheet casting (2)
Several are respectively arranged on the left side and the right side to be adapted with the groove (3) raised (4)；Upper piece casting (1) and bottom sheet casting
Connection is inlayed in the left and right sides of part (2) by the groove (3) and raised (4) respectively, forms the 3D printing and substitutes casting
Part.The 3D printing is substituted casting and is molded using 3D printing, can be according to the different parts of different patients acquisition casting and suffering limb
It is identical, to strengthen the fixation of suffering limb, and accelerates the healing of suffering limb.
The groove (3) is that upper piece casting (1) left and right sides is recessed to be formed, and is by CAD when using 3D printing casting
Software systems set program formation；The projection (4) is that bottom sheet casting (2) left and right sides protrudes out to be formed, and is with 3D printing
Program formation is set by CAD software system during casting.
The groove (3) and raised (4) are at least provided with 2, and the groove (3) and raised (4) are arranged at intervals, so as to
It is fixedly secured the different fracture sites of different patients.
Preferably, the groove (3) is compression pin insertion hole, and the projection (4) is compression pin, by compressing pin insertion hole
With being adapted to for compression pin, a casting (1) and bottom sheet casting (4) is set to be removably connected to one, in order to mount and dismount, and
Fixation to suffering limb；The groove (3) can also be neck；Raised also (4) can be buckle, pass through neck and card
The adaptation of button, makes a casting (1) and bottom sheet casting (4) be removably connected to one.
As shown in figure 3, it is the assembling schematic diagram that the 3D printing substitutes casting.Wherein, upper piece casting (1) and bottom sheet casting
Part (2) surrounds cavity structure (6), for housing the suffering limb after patient's bonesetting reduction therapy.In the present invention, upper piece casting (1) and
Bottom sheet casting (2) respectively by 3D technology use certain material printing shaping, therefore two panels casting can according to different parts, no
Similar shape, fracture fixation of different nature need to be bent, folded.
As shown in figure 4, it substitutes casting use state figure for the 3D printing of the orthopaedics gypsum of the present invention.When in use, on
Piece casting (1) and bottom sheet casting (2) wrap up suffering limb from the both sides of the suffering limb after patient's bonesetting reduction therapy, i.e., be positioned over suffering limb
Upper piece casting (1) and bottom sheet casting (2) are surrounded in cavity structure (6), and two panels casting cooperates, and then keeps two panels casting
Connection is inlayed in the corresponding groove in both sides (3) and raised (4), so that the outer fixation to suffering limb is realized, and its wearing and convenient disassembly.
The connection of the two panels casting is not limited to inlay the mode of connection；The 3D printing substitutes casting and can also used first by two panels casting
Side be fixedly connected, opposite side is linked together again when using.
Several air-vents (5) are respectively arranged with upper piece casting (1) and bottom sheet casting (2), more specifically, to suffering from
After limb is scanned, program is set by CAD software system, set that several are randomly distributed on two panels cast(ing) surface is saturating
Stomata, in order to ensure the intensity of casting, the area of air-vent is not more than 2/3rds of two panels casting area.The air-vent can
Strengthen the gas permeability of casting, suffering limb skin is fully contacted with outside air, prevent the long-term closed compression of disease sites, infection hair
It is scorching；Ultrasonic therapy or electromagnetic curing can be carried out to fracture site by air-vent simultaneously, so as to stimulate circulation, accelerate to suffer from
The healing of limb.In addition, the setting of air-vent can reduce casting weight, and it is easy to the healing state of doctor observation understanding patient.
3D printing of the present invention is substituted casting and is molded using 3D printing, can be cast according to the different parts of different patients
Being identical for part and suffering limb, to strengthen the fixation of suffering limb, and accelerates the healing of suffering limb.
The preparation method that 3D printing described in the embodiment of the present invention substitutes casting comprises the following steps：
1st, the state of an illness information of patient is obtained, bonesetting reduction therapy is carried out to patient first, then using the bonesetting of 3D scanner scannings
Suffering limb after reduction therapy, and scan image data is imported in the computer being connected with 3D scanners used.3D scannings used
Instrument can be the 3D laser scanners or hand-held 3D scanners of specialty, and they can accurately suffer within a short period of time
Limb information is convenient and the degree of accuracy is high.
2nd, according to scan image, by the CAD software default in computer substantially in symmetry shape two panels casting and
The program of raised, groove and air-vent etc., builds 3D mathematical models.
3rd, according to 3D mathematical models, the two panels casting is gone out using 3D printer and waterproof resin file printing.
3D printing of the present invention substitutes casting by the whole suffering limb of 3D scanner scannings, can be according to different people, difference portion
Position, fracture printing casting of different shapes, i.e., the suffering limb accurate fit that made casting can be with patient.
3D printing of the present invention is substituted casting and made using waterproof resin material, can be also made of ABS plastic, can
The water proofing property that the 3D printing substitutes casting is improved, therefore patient can have a bath, or even swimming, without worrying casting strength
Weaken.
Thus, 3D printing of the present invention substitutes casting and is a kind of waterproof, breathes freely, is easy to doctor to observe the state of an illness, and again
Amount is light, comfortable wearing, attractive in appearance, can substitute casting with the 3D printing of traditional orthopaedics gypsum of fracture site accurate fit again, can add
The recovery of fast fracture patient.
The foregoing is merely illustrative of the preferred embodiments of the present invention, and the scope of the present invention should not be limited with this, i.e., it is any not
Disengaging technical solution of the present invention content, any simple modification made according to technical spirit of the invention to above example, etc.
With change and modification, belong in the range of technical solution of the present invention.
