Specific embodiment
It please refers to shown in Fig. 1-3, a kind of half patch bone conduction plate specifically includes that guide plate 2 and fixed part, the guide plate 2
Upper surface is equipped at least one guide channel 1, and the lower end surface that 1 lower end of guide channel extends to guide plate 2 is stopped, guide channel 1
Agree with guiding point in direction.The fixed part contains at least one fixation kit, and fixation kit is by site 3 and at least one
A fixed channel 4 forms, and the upper surface of site 3 is arranged in fixed channel 4, and fixed 4 lower end of channel extends to site 3
Lower end surface stop, the lower end surface of site 3 and fixed point are agreed with, and site 3 is fixedly connected with guide plate 2.
In above-mentioned technical proposal, half, which pastes bone conduction plate, confirms that its positioning is pasted with being bonded for skeleton by site 3
Piece 3 is located at preset fixed point, to guarantee guide channel 1 and be oriented to the accurate matching of point, makes guide channel 1
Position error reduces, meanwhile, half, which pastes bone conduction plate, to install during surgery, pre-fix operation without carrying out before surgery, keep away
Exempt from the pain that repeated multiple times operation increases patient.
In a wherein embodiment, the fixed part contains there are two fixation kit, and fixation kit contains a fixation
Channel 4 is matched by two sites 3 with skeleton, and many places positioning is conducive to clinic and quickly judges compactness, can
Utmostly guarantee the accuracy of positioning.Reinforcing rod 5, reinforcing rod 5 and two fixations are connected between described two fixation kits
Channel 4 is all connected with, and reinforcing rod 5 can reduce the deformation in two fixed channels 4 in matching process, guarantees the position of site 3
It does not change, reinforcing rod 5 is not connect with site 3, is avoided the epidermal tissue between two sites 3 of excision, is reduced
Wound.
In a wherein embodiment, the fixed part contains a fixation kit, and fixation kit is containing there are two fixed
Channel 4, two fixed, and channel 4 is non-parallel is staggered, and the fixed pin 8 of intersection is squeezed by two fixed channels 4, guarantees guiding
The fixed intensity of plate 2.
The guide channel 1 includes the first guide channel 1a, the second guide channel 1b and third guide channel 1c, wherein the
One guide channel 1a fractures suitable for front pillar, and the second guide channel 1b and third guide channel 1c are suitable for sacral fracture or sacrum ilium
Abarticulation.Design multiple guide channels 1, it is only necessary to fixed at one to treat simultaneously to multiple fracture but also pre-
For guide channel 1, progress multi-reset is facilitated to fix.
The upper surface of the site 3 connect with guide plate 2 or is connect by fixed channel 4 with guide plate 2, i.e., fixed
Position patch 3 is connected directly between on guide plate 2 or site 3 is connected on fixed channel 4, fixed channel 4 and guide plate 2
It is connected and fixed.
The guide plate 2 and fixed part are integrally formed by 3D printing, are made entire guide plate based on 3D printing, can be guaranteed
The lower end surface of site 3 is agreed with fixed point and the direction of guide channel 1 is agreed with guiding point.
Specifically, carrying out replacement and fixation operation to fracture patient using half patch bone conduction plate, comprising the following steps:
One, guide plate makes
In replacement and fixation operation consent, CT scan is carried out to patient in advance, obtains skeleton data.Above-mentioned data are imported
MIMICS software simultaneously simulates skeleton, and attending physician designs fixed point and guiding point by software simulation and clinical experience
Then position passes through 3D printing production guide plate corresponding with subjects bones' size.
Two, guide plate is fixed
In replacement and fixation operation, the epidermal tissue near fixed point is cut, site 3 is placed in, it is slight to adjust
The position of site 3 is overlapped it with the fixation site of design.Fixed pin 8 is squeezed into fixed point out of fixed channel 4,
2 position of fixed guide plate, at this point, guide channel 1 is overlapped with the guiding point of design.
Three, replacement and fixation
Enter sleeve 7 to guiding point position out of guide channel 1, then squeeze into pilot pin 6 to guiding point out of sleeve 7,
The matching degree of pilot pin 6 and fracture is observed by developing apparatus, if matching, removes entire guide plate, squeeze into sky along pilot pin 6
Heart screw simultaneously takes out pilot pin 6, completes replacement and fixation.
In step 1, the fixed point is located at human body bone mark and more obviously locates, the tissue that when operation removes
It is few, reduce operating time and operation risk.Preferably, fixed point is the raised or sunken place of bone, makes site 3 and human body
Bone must be bonded more secured.
In step 3, the sleeve 7 has guiding role, when can prevent pilot pin 6 from puncturing in tissue
Bending and deflection, are further ensured that the accurate merging of pilot pin 6.
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.
