Description
Technical field
The present invention relates to medical instruments field, insert laser assisted position guiding device specifically for a kind of three-dimension virtual reality matching pedicle nail.
Background technology
Can pedicle screw internal fixation operation be a kind of operation critically important in current neurosurgery, be inserted by screw pedicle exactly and not damage the key that neural vertebral body is these operation success or failure.
And whether the approach position, direction and the angle that how to be accurately controlled pedicle nail in art determine it and can enter in vertebral body smoothly, this problem relating to pedicle nail is positioned.
At present the mode to pedicle nail location is divided into two big classes:
One class is preoperative location, its be utilize preoperative patient is done all kinds of scanning computed tomographies, MRI to be to determine lesions position, then rely on the path of insertion of the Professional knowledge plan pedicle nail of doctor and perform the operation, operation being aided with X-ray examination again and the path of insertion of pedicle nail is corrected and assists；
This is the most most common current way, but such method error is bigger, need repeatedly to carry out putting nail route with reference to constantly correction is actual by the image of X-ray examination in art, this by be greatly increased operation complexity, add operation ray exposed amount, add operating time, patient is proposed the highest requirement simultaneously.
If it addition, carry out repeatedly X-ray examination in operation also can increase the amount of radiation of patient and medical worker, human body being worked the mischief.
Another kind of is Intraoperative position navigation, this is one of the most state-of-the-art current location mode, it is known that the information constantly of probe location, guidance precisely operation, but it is expensive, being difficult to popularize, common City Hospitals, most County Hospital could not power be bought.
Thus, invent a kind of current City Hospitals and the actual demand of most County Hospital and purchasing power of meeting, can either be accurately positioned the most lower-cost pedicle screw positioning device simultaneously becomes the task of top priority.
Summary of the invention
It is an object of the invention to: provide one can either be accurately positioned the most lower-cost three-dimension virtual reality matching pedicle nail simultaneously and insert laser assisted position guiding device.
The present invention is achieved through the following technical solutions:
A kind of three-dimension virtual reality matching pedicle nail inserts laser assisted position guiding device, it is characterised in that: include positioning element, a pair for carrying out the positioning needle of pre-determined bit and a pair for drilling through the needle for trephination in duct on vertebra on vertebra；
