Specific embodiment
It please refers to shown in Fig. 1-2, one of technical solution of the present invention combines guide plate, mainly includes：Guide plate ontology 1 and solid
Determine portion, the lower end surface of the guide plate ontology 1 is agreed with binding face, and the upper surface of guide plate ontology 1 is equipped at least one guide channel
2, the lower end surface that the lower end of guide channel 2 extends to guide plate ontology 1 is stopped, and direction and the guiding point of guide channel 2 are agreed with, described
Fixed part contains at least one fixation kit, and fixation kit is made of site 4 and at least one fixation channel 3, fixed logical
The upper surface of site 4 is arranged in road 3, and the lower end surface that the lower end in fixed channel 3 extends to site 4 is stopped, site 4
Lower end surface agree with fixed point, site 4 is fixedly connected with guide plate ontology 1, and the upper surface of the guide plate ontology 1 is arranged
There is mark line 5.
The guide plate ontology 1 and fixation kit is integrally formed by 3D printing, can guarantee the lower end surface of guide plate ontology 1
With the compatible degree of binding face, the compatible degree in the direction of guide channel 2 and guiding point, the lower end surface of site 4 and fixed point
The compatible degree of position, after entire guide plate completes, the relative position in guide channel 2 and fixed channel 3 will not change.
In a wherein embodiment, the fixed part contains a fixation kit, and fixation kit is containing there are two fixed
Channel 3, two fixed, and channel 3 is non-parallel is staggered, and the fixed pin 8 of intersection is squeezed by two fixed channels 3, guarantees guide plate
The fixed intensity of ontology 1.
In a wherein embodiment, the fixed part contains there are two fixation kit, and fixation kit contains a fixation
Channel 3 is matched by two sites 4 with skeleton, and many places positioning is conducive to clinic and quickly judges compactness, can
Utmostly guarantee the accuracy of positioning.
The diameter in the fixed channel 3 is not less than the diameter of fixed pin 8, when the diameter in fixed channel 3 is greater than fixed pin 8
Diameter when, after squeezing into a fixed pin 8, the position of guide plate ontology 1 can be finely tuned, be conducive to positioning.
The mark line 5 is cross hairs, rectangular, triangle or circle, it is preferred that the mark line 5 is cross hairs, works as mark
When the height of note lamp changes, the relative position of light will not change.
The upper surface of the site 4 connect with guide plate ontology 1 or is connect by fixed channel 3 with guide plate ontology 1,
I.e. site 4 is connected directly between on guide plate ontology 1 or site 4 is connected on fixed channel 3, is fixed channel 3 and is led
Plate ontology 1 is connected and fixed.
The guide plate ontology 1 is equipped with several openings 6, and opening 6 has the function of the exposed visual field, can pass through opening 6
It is auxiliarily fixed and other operations.
It please refers to shown in Fig. 3-4, one of technical solution of the present invention combines the precise positioning method of guide plate, including following
Step：
1. determining patient focal area, position line is drawn in focal area, it is preferred that position line is cross hairs, in position line
Fixed several MARKER points, make all MARKER points be able to confirm that the shape of position line, i.e. MARKER point is located at cross hairs
Center and four endpoints, MARKER point are the iron plate that can develop under CT scan, and MARKER point is fixed by medical adhesive tape；
2. opening mark lamp, adjustment height is overlapped its light with position line, and fixation mark lamp position sets constant, closing mark lamp,
Preferably, mark lamp is laser lamp, and mark lamp is rack-mount, and mark lamp can move on bracket and adjust height；
3. carrying out CT scan to patient, forming virtual tag point and obtaining the data of human skin and bone, pass through virtual tag
Point confirm virtual tag area 5a, so that it is determined that on guide plate ontology 1 mark line 5 position；
4. the data of step human skin 3. and bone are imported into MIMICS software, by software to human skin and bone into
Row simulation, the selected and matched binding face of human skin, design and the matched guiding point of skeleton and fixed point, then
It is added by 3D printing production guide plate corresponding with binding face, guiding point and fixed point and in 1 upper surface of guide plate ontology
Mark line 5 corresponding with position line；
5. perform the operation, mark lamp is opened, after patient lies in operating table, patient location is adjusted, makes the light and position line of mark lamp
It is completely coincident；
6. cutting the epidermal tissue near fixed point, site 4 is placed in, the slight position for adjusting site 4 makes it
It is overlapped with the fixation point of design；
7. squeezing into fixed pin 8, the position of resting guide ontology 1 to fixed point out of fixed channel 3；
8. squeezing into pilot pin 7 to guiding point out of one of guide channel 2, pilot pin 7 and bone are observed by developing apparatus
Matching degree at folding is completed multiple if matching, removes entire guide plate, squeeze into hollow screw along pilot pin 7 and take out pilot pin 7
Position is fixed, if one guide channel 2 is not available, can use another guide channel 2 instead.
The step 6. in, if the light of mark lamp is not overlapped with mark line 5, adjusting 1 position of guide plate ontology makes to mark
The light of lamp is overlapped with mark line 5, is reverse-located by mark lamp, can carry out essence to the installation site of guide plate ontology 1
Really adjustment.
The step 8. in, before squeezing into pilot pin 7, need first to be placed in sleeve, sleeve has guiding role, being capable of anti-fastening
When puncturing in tissue bending and deflection occur for position needle 7, are further ensured that the accurate merging of pilot pin 7.
Preferably, fixed point is located at human body bone mark and more obviously locates, and the tissue that when operation removes is few, reduction
Operating time and operation risk；Preferably, fixed point is the raised or sunken place of bone, obtains site 4 with skeleton
It is bonded more secured.
Combination guide plate and its precise positioning method in above-mentioned technical proposal, positioned by guide plate ontology 1 and human skin,
Site 4 and skeleton position and mark line 5 and mark lamp positioning make guide plate actual installation position and be pre-designed
Point is consistent, and improves the validity and safety of operation.
Certainly, the above is only better embodiments of the present invention, and use scope of the invention is not limited with this, therefore, it is all
Equivalent change is made in the principle of the invention should be included within the scope of the present invention.
