Description
Technical field
The invention belongs to a kind of medical apparatus, the multi-functional percutaneous cervical arc root positioning that more particularly to a kind of bone surgery is used
Device.
Background technology
In clinic, orthopedist can run into various spine disorderses, for example, disc herniation, spinal canal stenosis, vertebra side
Curved, spine fracture, tuberculosis and tumour etc..These diseases are required for pedicle to punch or pedicle screw in operative treatment,
It is fixed or orthopedic, or expansion is strutted by pedicle of vertebral arch row compressed vertebral, injects bone cement to treat vertebral compression fracture.
And the foundation of pedicle channel, to perform the operation success it is critical that.When pedicle channel is set up, first have to determine to set up
The position and direction of pedicle channel.At present, the method for setting up pedicle channel position and direction mainly has two kinds, and one kind is to cut
Open, another kind is percutaneous positioning.Incision is exactly to cut skin, peels off paravertebral muscles, vertebral posterior structures is exposed, straight
Depending on the position and direction of lower determination pedicle channel.Although this method comparing is directly perceived, also it is easier to determine pedicle channel
Position and direction, it also requires the almost whole auxiliary of X-ray, especially continuous adjustment direction, beginner, start X-ray
Number of times is more, and this has very big harm to medical worker and patient.And, the injury that this method is caused to patient is very
Greatly, after musculature is peeled off from vertebra, its blood vessel, muscle and nerve fiber can be subject to serious destruction, although musculature
Can heal, but be difficult to return to original state, and, hand intraoperative hemorrhage is more, and the pain of patient is big, and convalescence is also very long.
Due to angle it is difficult to control, pedicle screw is difficult to keep straight line in art.Percutaneous positioning is percutaneous cervical arc root technique for fixing, this
The technology of kind is exactly, by one small otch of skin, to be not required to peel off muscle, and pedicle of vertebral arch position is determined in the body surface of patient by means of X-ray
Put.This accuracy requirement to pedicle of vertebral arch positioning is higher, and difficulty is also bigger, during positioning and operation, even more needs anti-
The position and direction for starting X-ray again to correct and determine pedicle channel, this just causes bigger to medical worker and patient
Harm, even if the pedicle channel being built such that, does not often reach preferable position and direction, and then influence the effect of operation yet
Really.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, there is provided it is a kind of to medical worker and patient harm it is small,
The multi-functional percutaneous cervical arc root locator that rapidly, accurately can be positioned to pedicle channel pilot pin.
The present invention has a sticker, there is two positioning terminals on sticker, and end slipway is provided with positioning terminal,
Transverse slipway is installed on end slipway, positioning seat is installed on transverse slipway, lateral rotation is installed on positioning seat and is determined
Potential head, is provided with lateral rotation positioning head and longitudinally rotates locating piece, there is installation pilot pin on locating piece is longitudinally rotated, and leads to
End slipway and transverse slipway are crossed by the entry point of the tip alignment pedicle channel of pilot pin, by lateral rotation positioning head and
The direction that locating piece determines pilot pin is longitudinally rotated, so as to accurately determine the position and direction of pedicle channel.
There is the scale for representing angle respectively on positioning seat and lateral rotation positioning head, there is one on locating piece is longitudinally rotated
0 degree of line of bar, in order to determine the direction of pilot pin.
The advantage of the invention is that：
The 1st, end slipway is set, and transverse slipway is set on end slipway, realize pilot pin needle point in longitudinal and transverse two directions
Adjustment, the needle point of pilot pin is accurately directed at the entry point of pedicle channel, lateral rotation positioning is set on positioning seat
Head, sets on lateral rotation positioning head and longitudinally rotates locating piece, realizes to pilot pin space angle in longitudinal and transverse two directions
Adjustment, be completely superposed the direction of pilot pin and the direction of pedicle channel of setting, realize noninvasive positioning, can meet not
Enter the requirement of needle passageway with angle, and positioning is rapid, accurate, it is easy to adjust.
2nd, position fixing process only needs 2 ~ 3 X-ray lines to have an X-rayed, and medical worker can avoid during perspective, reach medical worker and penetrated with X
Line zero is contacted, and the harm to medical worker and patient is small.
3rd, range of application is wide, can be used for the operation of lumbar vertebrae, thoracic vertebrae each sections, it can also be used to the articular process of foramen intervertebrale lens into
Shape Path Setup.
