Accompanying drawing explanation
Fig. 1 the present invention is based on the human vertebra structural representation in the spinal osteotomy assembling teaching mode of 3 D-printing;
Fig. 2 is the spinal osteotomy based on 3 D-printing of the present invention assembling teaching mode structural representation.
Embodiment
The technological means realized to make the present invention, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed the assembling of the spinal osteotomy based on 3 D-printing teaching mode of the present invention by reference to the accompanying drawings.
Embodiment 1
Fig. 1 is that the present embodiment is based on the human vertebra structural representation in the spinal osteotomy assembling teaching mode of 3 D-printing
In order to better understand the assembling of the spinal osteotomy based on the 3 D-printing teaching mode that the present embodiment provides, the vertebra of composition based on the spinal osteotomy assembling teaching mode of 3 D-printing is introduced.
As shown in Figure 1, A is the vertical view of a vertebra, B is its side view, vertebra comprises centrum 1 as main body and the pedicle of vertebral arch 2 that is connected on centrum 7, raised structures is distributed in respectively: processus articular superior 3 at the edge away from centrum of pedicle of vertebral arch 11, spinous process 4, also has transverse process 5 on spinous process 4 top simultaneously.Examine simultaneously and can find, at pedicle of vertebral arch about 2, also there is superior vertebral notch 6 and inferior vertebral notch 8.
Be connected to each other in structure at two vertebras of reality, rely on inferior articular process 9 and transverse process 5 and fasten mutually, the lower projection simultaneously going up a spinous process 4 is just coincide with the upper recess of next spinous process and is perfectly stitched together, as chain, fasten mutually the backbone forming human body.
Fig. 2 is the assembling of the spinal osteotomy based on the 3 D-printing teaching mode structural representation of the present embodiment
The assembling of the spinal osteotomy based on the 3 D-printing teaching mode that the present embodiment provides, vertebra is wherein set up stereoscopic model by human spine 3 Dimension Image Technique and is obtained by three-dimensional printing technology, and used herein is that spiral CT modeling obtains.
Based on the spinal osteotomy assembling teaching mode 100 of 3 D-printing, as shown in Figure 2, by the split of 9 vertebras 10 together, have osteotomy three osteotomy blocks: SPO osteotomy block 20, PSO osteotomy block 30, VCR osteotomy block 40 simultaneously, lay respectively in the 3rd, 5,7 vertebra, hinge 11 and 12 is separately positioned on corresponding 3, between 4,5 centres and 6, between 8, couple together mobilizable for the vertebra of correspondence.
As shown in filling part in Fig. 2, SPO osteotomy block 20 comprises inferior articular process, the transverse process structure of vertebra, uses red-label;
As shown in filling part in Fig. 2, PSO osteotomy block comprises the inferior articular process of vertebra, transverse process and pedicle of vertebral arch structure, uses Green Marker;
As shown in filling part in Fig. 2, VCR osteotomy block comprises the entire infrastructure of the centrums such as the inferior articular process of vertebra, transverse process and pedicle of vertebral arch, uses blue markings.
Hinge 11 and 12, hinge body is an elastic plate, and use the elastic caoutchouc that same bone color is identical in the present embodiment, there is through hole at two ends, and through hole is fixedly connected on the centrum outer rim of vertebra for screw passes.Wherein 11 is shorter, is screwed in the metal nuts being embedded in vertebra 10 inside by screw.And 12 owing to connecting two vertebras, comparatively 11 is long, and screw is with six simultaneously, and each 3 of two, is triangularly arranged, and 11 is similar together, is screwed into equally in the metal nuts being embedded in vertebra 10 inside by screw.
During use, each osteotomy block 20 in advance, 30,40 is clamped by the elastic plate applying elastic force of hinge 11 or 12 and inlay in a model, during use, explanation person makes elastic clamping power disappear by slightly being pulled toward the right in diagram 2 by the hinge of correspondence, corresponding osteotomy block can be made to get loose from two vertebras and take out, namely complete explanation presentation process.
The process be loaded into, similar with the process taken out, be break hinge into two with one's hands breach is opened equally, after then being put in by the osteotomy block of correspondence, unclamp hinge.
The effect of embodiment and beneficial effect
The assembling of the spinal osteotomy based on the 3 D-printing teaching mode that the present embodiment provides, has: dismountable osteotomy block, is arranged between vertebra inside or adjacent two vertebras; And hinge, be arranged between the vertebra both sides with osteotomy block of correspondence or the centrum of adjacent two vertebras, the connection for correspondence has the vertebra of osteotomy block or adjacent two vertebras, and such design, makes:
First, dismountable osteotomy block, can explain the osteotomy region of different bone-culting operation in spinal osteotomy technology intuitively;
Secondly, make to be hinged, can come conveniently different osteotomy block to be taken out and put into, repeated multiple times demonstration by the folding of hinge, student can oneself object operation simultaneously, has deepened cognition;
The more important thing is, hinge can be movable, the stressed situation of other vertebras in the spine model after taking out osteotomy block can be shown intuitively, deepened student to the postoperative understanding to patient effect of various bone-culting operation.
The assembling of the spinal osteotomy based on the 3 D-printing teaching mode that the present embodiment provides, the vertebra used is obtained by three-dimensional printing technology by setting up stereoscopic model by human spine 3 Dimension Image Technique, make spine model more true to nature, be more conducive to topic teaching.
The assembling of the spinal osteotomy based on the 3 D-printing teaching mode that the present embodiment provides, different osteotomy block: the different color mark that SPO osteotomy block, PSO osteotomy block, VCR osteotomy block use, show the osteotomy scope of different bone-culting operation intuitively, be easy to student's learning and memory.
The assembling of the spinal osteotomy based on the 3 D-printing teaching mode that the present embodiment provides, use elastic hinge, can provide elastic clamping power, make osteotomy block can by simply breaking action into two with one's hands to dismantle and assembling, elastic clamping power makes osteotomy block not easily to get loose loss simultaneously.
