Description
Technical field
The present invention relates to medical instruments field, and laser assisted is inserted specifically for a kind of three-dimension virtual reality fitting pedicle nail
Position guiding device.
Background technology
Can pedicle screw internal fixation operation be a kind of operation critically important in current neurosurgery, exactly by screw
Pedicle is inserted without damaging the key that neural centrum is the operation success or failure.
And approach position, direction and the angle for how being accurately controlled pedicle nail in art determine whether it can be suitable
The problem of profit is entered in centrum, and this relates to position pedicle nail.
Two major classes are divided into the mode of pedicle nail positioning at present：
One kind is preoperative positioning, and it is to determine lesions position using the preoperative all kinds of scanning computed tomographies done to patient, MRI, and
Rely on the path of insertion of the professional knowledge plan pedicle nail of doctor afterwards and performed the operation, be aided with X-ray examination in operation again to vertebra
The path of insertion of nut nail is corrected and aided in；
This is current clinically most common way, but such method error is larger, it is necessary to repeatedly by x-ray in art
The image of perspective carries out actually putting nail route with reference to constantly amendment, this by the complexity for greatly increasing operation, add operation
Ray exposed amount, operating time is added, while very high requirement is proposed to patient.
If in addition, multiple X-ray examination is carried out in operation can also increase the amount of radiation of patient and medical worker, to human body
Damage.
Another kind of is Intraoperative position navigation, and this is one of current positioning method state-of-the-art in the world, it is known that probe
The constantly information of position, precisely operation is instructed, but its is expensive, it is difficult to popularize, it is common City Hospitals, big absolutely
Most County Hospitals could not power purchase.
Thus, invent a kind of actual demand for meeting current City Hospitals and most County Hospitals and purchase energy
Power, can either be accurately positioned while lower-cost pedicle screw positioning device turns into the task of top priority again.
The content of the invention
It is an object of the invention to：Offer one kind can either be accurately positioned while lower-cost three-dimension virtual reality is intended again
Close pedicle nail and insert laser assisted position guiding device.
The present invention is achieved through the following technical solutions：
