In the present embodiment, the minimal invasive lumbar surgery guide plate is the medical instrument applied in the course of surgery, should
With enough physical arrangement property, to meet requirement when performing the operation.Specifically, the skin pasting board, guiding tube, guide sleeve
And positioning guide pin sleeve should use the material with some strength and toughness to be made, such as polyamide fiber material.
It is capable of providing the same of enough intensity and toughness using minimal invasive lumbar surgery guide plate made of polyamide fiber material
When, additionally it is possible to there is preferable bio-compatibility, be conducive to use during surgery.
In some embodiments, the aperture of the guiding tube specifically could be provided as 7.0mm, with the positioning guide pin sleeve
It matches.More specifically, the first aperture of the guide sleeve 30 is 9.0mm, and 40 second aperture of positioning guide pin sleeve is
1.5-4.0mm.By the way that the pore size parameter is arranged, the mutual cooperation between three can be realized very well, while meeting reinforcing
Structure ensures the requirement that positioning guide pin is smoothly placed in.
Manufacturing process schematic diagram below in conjunction with minimal invasive lumbar surgery guide plate shown in Fig. 4 and user shown in fig. 5
The method flow diagram of method, the complete application flow of detailed description minimal invasive lumbar surgery guide plate.
It is planned as shown in figure 4, manufacturing process includes mainly medical imaging（S100）, three-dimensional modeling design（S200）And 3D
Printing and making（S300）Three steps.
In step 100, first, the CT figures provided according to doctor and message of performing the operation, will with medical imaging software
Graphics is presented in CT, direction, position and the quantity that the vertebral arch for then cooking up back to skin from medical image software is followed closely, most
Extract skin afterwards, lumbar vertebrae data reach 3 d modeling software.
In step 200, first, by 3 d modeling software, by the lumbar vertebrae extracted, skin and into nail path, root
According to layout data, corresponding skin paste Slab is designed.Then, according to skin paste Slab, it is fixed that guiding tube, cross are cooked up
Position slot, guide sleeve, the positioning corresponding model parameter of guide pin sleeve.
In step 300, according to the 3 D stereo parameter or model of step 200 design, in a manner of 3D printing, with poly-
The minimal invasive lumbar surgery guide plate is made in nylon material.
As shown in figure 5, after the completion of prepared by the minimal invasive lumbar surgery guide plate, following operating procedure can be carried out：
501, it is sterilized in affected part, finds out body surface corresponding point, carry out percutaneous cervical arc root tack operation positioning.
502, by minimal invasive lumbar surgery guide plate place affected part, by metal bar be placed on cross locating slot correspondence find out it is opposite
Point exposes and shines X-ray, confirms position.
503, guide sleeve and positioning guide pin sleeve are sequentially first put into guiding tube by operation consent.
504, the positioning of percutaneous cervical arc root tack operation is come into effect, guide pin is first punctured into skin extremely along positioning guide pin sleeve
Pedicle of vertebral arch simultaneously enters centrum.
505, after positioning guide pin approach confirms, positioning guide pin sleeve is taken out, starts to apply pedicle nail operation.
In conclusion the minimal invasive lumbar surgery guide plate that the utility model embodiment provides need not assisted using calculator
In the case of navigation method, it also can be good at improving accuracy rate and the safety for setting nail.As the auxiliary in surgical procedure, guiding
Instrument can enable doctor easily carry out the positioning of vertebral arch tack operation, and nail accuracy and the operating time that effectively shortens are set in raising, are reduced
Doctor and corrective surgery risk.
The foregoing is merely the embodiments of the utility model, and it does not limit the scope of the patent of the present invention, all
It is equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly or indirectly uses
In other related technical areas, it is equally included in the patent within the scope of the utility model.
