Description
Technical field
The utility model is related to the field of medical instrument technology, specifically, the utility model is related to 3D printing guide plate skills
Art field.
Background technology
3D printing technique is directly successively or point by point to accumulate three-dimension object from computer model with material, as computer
Auxiliary manufacture（CAM）One kind in technology being successfully applied to all various aspects of medical domain in recent years.Medical Imaging Technology
It is combined with 3D printing technique, makes medical image not only from two dimensional surface Image Development to 3 D stereo, and develop to current device
The mock-up of official.Further with CAD（CAD）In conjunction with, place's human anatomic structure model can be not only manufactured,
And the individual operation guide plate exactly matched with human anatomic structure surface can be produced and come.
Minimally invasive spine surgical is carried out increasingly extensive at present, including percutaneous vertbroplasty（PVP）Or balloon kyphoplasty
（PKP）Or the advantages that percutaneous cervical arc root ligamentopexis, foramen intervertebrale lens, intervertebral disc mirror, tumor of spine lesion biopsy be operation wound it is small,
Restore fast, it is good to suffer from acceptance.And Minimally Invasive Surgery is percutaneous operation, by vertebra skin of back, is only capable of substantially determining centrum
Position, therefore be difficult merely the exact operation centrum position of identification by centrum dorsal skin, at this time in order to determine operation centrum,
Ensure to set accurate needle angle and depth when nail, accurately determine the entry point of pedicle and into nail direction, needs to carry out more
A large amount of x-ray bombardments are determined.This not only causes prodigious actual bodily harm and financial burden to patient, such as the ray of large dosage
Projection is often easy to cause postoperative nausea, the adverse reactions such as vomiting.Also unpredictable ray is caused to influence doctor simultaneously,
Even cause tumour.Though oneself is through there is in more advanced art CT add the lower pedicle screw merging technology of navigation at present, can reach compared with
High screw is placed in accuracy rate, but equipment is expensive, and the hospital that state's interior energy is equipped with such equipment is very rare.
3D printing vertebra Minimally Invasive Surgery is oriented to plate technique can provide a good solution thus.Patent CN
204863422 U patents disclose a kind of vertebra guide plate of 3D printing, but need that polylith locating plate, root is arranged when in use
That piece locating plate is selected to be used as final positioning according to CT scan data confirmation, and locating plate used needs to paste always
Until operation terminates on patient skin, this prevents the position below locating plate from sterilizing, and operation risk is increased, but also should
For technology during surgery using being restricted, 104287815 A of patent CN use metal sleeve, increase error, are finally determining
Any block centrum carry out operation and when guide plate placement location before two patented methods there is still a need for X-rays to be repeatedly scanned with,
The accurate placement to guide plate can be realized, to X in art when prior art guide plate being caused not to be avoided that percutaneous cervical arc root operation still
The dependence of ray scanning.
Invention content
For in the prior art it is preoperative lead to guide plate poor accuracy because of position factor, be not avoided that vertebra Minimally Invasive Surgery when
Dependence and guide plate position fixing process to CT scan in art are cumbersome and are unable to reach the state of the art of operation sterility requirements, this reality
With a kind of Digital location minimally invasive spine surgical 3D printing guide plate of novel offer, position is used when CT extracts data in the preoperative
Frame is recorded using the arbitrary edge of survey tool measurement and positioning block at a distance from the intersection point to operation centrum central point of backbone central axes
For a values；The vertical range for measuring operation centrum central point to skin surface again is recorded as b values；It can logistic by a values and b values
The exact position that middle guide plate is placed needs the distance that upper and lower translation is finely tuned to be recorded as c values on backbone center line.According to quilt
The mark line and a values of test object locating piece surrounding, b values and c values can utilize locating piece weight in tested object backbone skin region
The position that guide plate is placed in new mark art, this thoroughly solves the dependence to CT scan in operation, and broken away from it is preoperative extremely
The drawbacks of positioning device cannot be removed in art, the disinfection in surgery area is not influenced, it is extensive suitable through having in vertebra Minimally Invasive Surgery
The property used.
To achieve the goals above, this practicality provides a kind of technical solution：
The utility model provides a kind of Digital location minimally invasive spine surgical 3D printing guider, including guide plate and
The locating piece of mating setting is provided with locating piece cavity among the guide plate, and locating piece cavity both sides are provided with pilot hole, lead
Spinous process position line is provided among to back, locating piece is provided with locating piece in cavity.
In the utility model, locating piece one side central axes side is provided with T-shaped groove, and T-shaped groove runs through locating piece
Setting, guide plate bottom surface are provided with T-shaped fixed groove, and Position Scale is provided in T-shaped fixed groove, and Position Scale is in T
Font is adapted setting with the T-shaped fixed groove of guide plate and the T-shaped groove of locating piece, and Position Scale surface is provided with scale.
In the utility model, the length of zero graduation to end is consistent with T-shaped fixed groove length on Position Scale.
In the utility model, guide plate both sides setting cavity.
Following advantageous effect can be obtained by implementing technical solution provided by the utility model:
Digital location minimally invasive spine surgical 3D printing guide plate provided by the utility model, it is fixed to make in conjunction with digitized measurement
Position process optimization, it is easy, it is incorporated in the label that tested object epidermis is done according to a values, b values and c values is measured and can directly carry out two
Secondary positioning, without detent mechanism to be fixed on tested object for a long time, avoiding can not be to tester's art area in art
The inconvenience such as disinfection completely；Also make fast and accurately to determine point of puncture in doctor's art, and ensure to puncture direction in coronal-plane and sagittal
Face reaches accurate simultaneously, compared with traditional operation mode, can shorten operating time, reduce the exit dose of doctor and patient in art, improve hand
The safety of art and accuracy have wide applicability in vertebra Minimally Invasive Surgery field.
