It please refers to shown in Fig. 1-2, a kind of combination guide plate, specifically includes that guide plate ontology 1 and fixed part, the guide plate ontology 1
Lower end surface agree with binding face, the upper surface of guide plate ontology 1 is equipped at least one guide channel 2, and the lower end of guide channel 2 is prolonged
The lower end surface for extending to guide plate ontology 1 is stopped, and direction and the guiding point of guide channel 2 are agreed with, and the fixed part contains at least one
Fixation kit, fixation kit are made of site 4 and at least one fixation channel 3, and fixed channel 3 is arranged in site 4
Upper surface, the lower end surface that the lower end in fixed channel 3 extends to site 4 stops, the lower end surface of site 4 and fixed point
Agree with, site 4 is fixedly connected with guide plate ontology 1, and the upper surface of the guide plate ontology 1 is provided with 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 referring to shown in Fig. 3-4, one of technical solutions of the utility model combine the precise positioning method of guide plate, including
Following steps:
1. determining patient focal area, position line is drawn in focal area, it is preferred that position line is cross hairs, is being positioned
Several MARKER points are fixed on line, all MARKER points is made to be able to confirm that the shape of position line, i.e. MARKER point is located at cross
The center of line and four endpoints, MARKER point are the iron plate that can develop under CT scan, and MARKER point is solid by medical adhesive tape
It is fixed；
2. opening mark lamp, adjustment height is overlapped its light with position line, and fixation mark lamp position sets constant, closing mark
Remember lamp, it is preferred that mark lamp is laser lamp, and mark lamp is rack-mount, and mark lamp can move on bracket and adjust height
Degree；
3. carrying out CT scan to patient, forming virtual tag point and obtaining the data of human skin and bone, by virtual
Mark point confirms 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 MIMICS software, by software to human skin and bone
Bone is simulated, the selected and matched binding face of human skin, design and the matched guiding point of skeleton and fixed point,
Then by 3D printing production guide plate corresponding with binding face, guiding point and fixed point and in 1 upper surface of guide plate ontology
Add mark line 5 corresponding with position line；
5. perform the operation, mark lamp is opened, after patient lies in operating table, adjusts patient location, make the light of mark lamp and is determined
Bit line is completely coincident；
6. cutting the epidermal tissue near fixed point, site 4 is placed in, the slight position for adjusting site 4,
It is overlapped it 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 is observed by developing apparatus
It is complete if matching, removes entire guide plate, squeeze into hollow screw along pilot pin 7 and take out pilot pin 7 with the matching degree of fracture
At replacement and fixation, if one guide channel 2 is not available, another guide channel 2 can be used 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 in above-mentioned technical proposal passes through guide plate ontology 1 and human skin positioning, site 4 and human body
Bone positioning and mark line 5 are positioned with mark lamp is consistent guide plate actual installation position with the point being pre-designed, and mentions
The validity and safety of height operation.
Certainly, the above is only the preferred embodiment of the utility model, and the use scope of the utility model is not limited with this,
Therefore it is all made in the utility model principle it is equivalent change should be included in the protection scope of the utility model.
