Abstract
The invention relates to a medical device, in particular to a fixing device for a 3D printing template for puncturing. The fixing device comprises a three-axis rectangular coordinate system navigation support and a middle connecting piece, wherein the upper end of the middle connecting piece is connected with the three-axis rectangular coordinate system navigation support, and the lower end of the middle connecting piece is connected with the 3D printing template. The 3D printing template is fixed by the three-axis rectangular coordinate system navigation support and the angle of the 3D printing template is spacially regulated, so that the 3D printing template can be stably and accurately reset on the body surface of a patient and thus the tumor target section is precisely reset; the 3D printing template is stably fixed on the body surface of the patient in the whole puncture surgery process and thus the problem that the tumor target section cannot be precisely reset by the result of human factors and surgical factors is effectively solved.
Description
Technical field
The present invention relates to medical apparatus and instruments, a kind of fixing device puncturing use 3D printing template.
Background technology
The rise of 3D printing technique the most therewith, for each position of whole body by 3D printing technique produce coplanar, non-co-planar, the puncture template of different needle angles is gradually applied to clinic, can only be hand steered by patient assistant or fixing with adhesive plaster local but current 3D prints puncture template, realize 3D and print the reset puncturing template, so 3D prints the reset precision of puncture template and is easy for being affected by anthropic factor and intraoperative factors, the target area reset precision causing 3D printing template is poor, and then cause therapeutic effect the best, in art, practical operation perfect cannot restore preoperative plan.
Summary of the invention
Present invention seek to address that the problems referred to above, thus provide a kind of and 3D printing template can be made can stable and accurate to carry out resetting, improve at patient body-surface the fixing device of puncture 3D printing template of tumor target reset precision.
The present invention solves described problem, the technical scheme is that
A kind of fixing device puncturing use 3D printing template, including three axle rectangular coordinate systems navigation support, intermediate connectors, intermediate connector upper end is connected with three axle rectangular coordinate systems navigation supports, and intermediate connector lower end is connected with 3D printing template.
Using the present invention of technique scheme, compared with prior art, its prominent feature is:
Fix union space by three axle rectangular coordinate system navigation supports and adjust 3D printing template angle, 3D printing template is made stable and accurate to reset at patient body-surface, and then realize tumor target reset accurately, and make the body surface being fixed on patient highly stable during whole puncturing operation of 3D printing template, effectively prevent because anthropic factor and intraoperative factors cause tumor target to reset problem the most accurately.
As preferably, the present invention further technical scheme is:
Intermediate connector is stepped construction, grip block, middle body surface including upper end promote riser, the connecting plate of lower end, the grip block using stepped construction that intermediate connector upper end can be made to be connected with three axle rectangular coordinate system navigation supports is raised, make the connecting portion of three axle rectangular coordinate system navigation supports away from patient skin, meet sterility requirements and facilitate the angle adjustment of 3D printing template.
Connecting plate and body surface promote and are provided with reinforcement gusset between riser.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation；
Fig. 2 is the structural front view of embodiment of the present invention stepped construction；
Fig. 3 is the top view of Fig. 2；
In figure: three axle rectangular coordinate system navigation supports 1；Grip block 2；Body surface promotes riser 3；Strengthen gusset 4；Connecting plate 5；3D printing template 6.
Detailed description of the invention:
Below in conjunction with embodiment, the invention will be further described, and purpose is only that and is more fully understood that present invention, and therefore, the cited case is not limiting as protection scope of the present invention.
See Fig. 1, Fig. 2, Fig. 3, intermediate connector is stepped construction, grip block 2 including upper end, middle body surface promotes riser 3, the connecting plate 5 of lower end, grip block 3 is clamped on three axle rectangular coordinate system navigation supports 1, connecting plate 5 is connected with 3D printing template 6, connecting plate 5 and body surface promote and are provided with reinforcement gusset 4 between riser 3, retaining part on grip block 2 relative to CT scan image in X-axis, Y-axis, on Z axis it is all 0 degree, use stepped construction that the retaining part on grip block 2 can be made to raise, make the connecting portion of three axle rectangular coordinate system navigation supports 1 away from patient skin, meet sterility requirements and facilitate the angle adjustment of 3D printing template 6.
Complete 3D printing template 6 of sterilizing is compareed skin-marker and carries out body surface reset, make patient body-surface labelling point and the labelling point one_to_one corresponding in 3D printing template 6, after body surface resets successfully, three axle rectangular coordinate system navigation supports 1 are used to fix 3D printing template 6, and skin-marker remain with template mark point corresponding in the case of, the angle adjusting 3D printing template 6 makes X-axis, Y-axis, the angle of Z axis be 0 degree (generally need not the adjustment of wide-angle), to accomplish the accurate reset of template.
This device is fixed union space by three axle rectangular coordinate system navigation supports 1 and is adjusted 3D printing template 6 angle, 3D printing template 6 is made stable and accurate to reset at patient body-surface, and then realize tumor target reset accurately, and make the body surface being fixed on patient highly stable during whole puncturing operation of 3D printing template 6, effectively prevent because anthropic factor and intraoperative factors cause tumor target to reset problem the most accurately.
The foregoing is only the embodiment that the present invention is the most feasible, not thereby limit to the interest field of the present invention, the equivalence change that all utilization description of the invention and accompanying drawing content thereof are made, within being both contained in the interest field of the present invention.
Claims (3)
1. one kind punctures by the fixing device of 3D printing template, it is characterised in that: including that three axle rectangular coordinate system navigation support, intermediate connectors, intermediate connector upper end are connected with three axle rectangular coordinate system navigation supports, intermediate connector lower end is connected with 3D printing template.
The fixing device of puncture 3D printing template the most according to claim 1, it is characterised in that: intermediate connector is stepped construction, and grip block, middle body surface including upper end promote riser, the connecting plate of lower end.
