Description
Technical field
The utility model belongs to a kind of medical apparatus, the multi-functional percutaneous cervical arc root that more particularly to a kind of bone surgery uses
Locator.
Background technology
In clinic, orthopedist can run into a variety of spine disorderses, for example, disc herniation, spinal canal stenosis, vertebra side
Curved, spine fracture, tuberculosis and tumour etc..These diseases are required for pedicle punching or pedicle screw in operative treatment,
It is fixed or orthopedic, or expansion is strutted by pedicle of vertebral arch row compressed vertebral, bone cement is injected, to treat vertebral compression fracture.
And the foundation of pedicle channel, the success to operation are vital.When establishing pedicle channel, first have to determine to establish
The position and direction of pedicle channel.At present, the method for establishing pedicle channel position and direction mainly has two kinds, and one kind is to cut
Open, another kind is percutaneously to position.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 comparison is directly perceived, also it is easier to determine pedicle channel
Position and direction, it also requires the auxiliary that X-ray is almost whole, continuous adjustment direction, especially beginner, starts X-ray
Number is more, and this has very big harm to medical worker and patient.Moreover, this method injures very to caused by patient
Greatly, after musculature is peeled off from vertebra, its blood vessel, muscle and nerve fiber can be by serious destructions, although musculature
It can heal, but be difficult to return to original state, moreover, hand intraoperative hemorrhage is more, 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
Kind technology is exactly by one small otch of skin, is not required to peel off muscle, pedicle of vertebral arch position is determined in the body surface of patient by means of X-ray
Put.The accuracy requirement that this is positioned to pedicle of vertebral arch is higher, and difficulty is also bigger, during positioning and operation, even more needs anti-
X-ray is started again to correct and determine the position of pedicle channel and direction, and this just causes bigger to medical worker and patient
Harm, even if the pedicle channel being built such that, preferable position and direction are not often reached, and then influence the effect of operation yet
Fruit.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of that medical worker and patient are endangered
Multi-functional percutaneous cervical arc root locator that is small, rapidly, accurately being positioned to pedicle channel pilot pin.
The utility model has a sticker, has two positioning terminals on sticker, longitudinal cunning is provided with positioning terminal
Road, transverse slipway is installed on end slipway, positioning seat is installed on transverse slipway, be provided with positioning seat and laterally turn
Dynamic positioning head, is provided with lateral rotation positioning head and longitudinally rotates locating piece, has installation to position on locating piece is longitudinally rotated
Pin, by end slipway and transverse slipway by the entry point of the tip alignment pedicle channel of pilot pin, determined by lateral rotation
Potential 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 utility model has the advantage of：
The 1st, end slipway is set, and transverse slipway is set on end slipway, realizes pilot pin needle point in longitudinal and transverse two sides
Upward adjustment, the needle point of pilot pin is accurately directed at the entry point of pedicle channel, lateral rotation is set on positioning seat
Positioning head, set on lateral rotation positioning head and longitudinally rotate locating piece, realized to pilot pin space in longitudinal and transverse two directions
The adjustment of angle, the direction of pedicle channel of the direction of pilot pin with setting is completely superposed, noninvasive positioning is realized, can expire
Sufficient different angle enters the requirement of needle passageway, and positions rapidly, accurately, easy to adjust.
2nd, position fixing process only needs 2 ~ 3 X-ray lines perspective, and medical worker can avoid during perspective, reach medical worker and penetrated with X
Line zero contacts, and the harm to medical worker and patient is small.
3rd, application is wide, available for lumbar vertebrae, the operation of each section of thoracic vertebrae, it can also be used to the articular process of foramen intervertebrale lens into
Shape Path Setup.
