Description
Technical field
The utility model is related to a kind of spinal surgery auxiliary instruments, and in particular to one kind is for instructing spinal surgery to set
The two-dimentional reference column guided mode sleeve-board part of nail.
Background technology
Protrusion of lumber intervertebral disc caused by cervical spondylosis caused by cervical vertebra degeneration, spinal canal stenosis and lumbar retrogression
The diseases such as disease, lumbar spinal stenosis, Lumbar segmental instability, lumbar spondyloiisthesis are clinically very common.These diseases can cause
Neck and shoulder ache, pain in the back and lower limb pain are numb, the clinical symptoms of intermittent claudication or even stool and urine and sex dysfunction, seriously
Influence the life and health and quality of life of patient.With the gradual quickening of people's rhythm of life, and aging society by
Step arrives, cervical spondylosis, lumber ertebral disc degenerative disease incidence in growth trend year by year, how to treat lumber ertebral disc degeneration
Disease is a big clinical important topic.Spinal column pressure reduction fusion internal fixation is current treatment cervical spondylosis, stenosis, lumbar vertebrae
The main means of the diseases such as disc herniation, lumbar spinal stenosis, Lumbar segmental instability, lumbar spondyloiisthesis, spinal column pressure reduction of being expert at melt
Need to carry out backbone when closing internal fixation to set nail, but due to pushing to from waist on, thoracic vertebrae, cervical vertebra the diameter of root of pulling the bow gradually subtract
Small, anatomy of spine is complicated, carries out the fixed difficulty of pedicle screw and danger is high, accidentally set, may cause once screw occurs
Blood vessel, neurotrosis bring very big damage, and it is difficult universal in clinic to lead to the pedicle of vertebral arch technology of thoracic vertebrae and cervical vertebra, therefore how

The development of art, using the rise of reverse technology and rapid prototyping technology, for medical domain, accurately operation provides technical support.Instead
The combination for asking engineering and Quick-forming brings a kind of completely new product design, manufacture and three-dimensional dimension measurement pattern.In medicine
Field, people attempt reverse engineering is combined with Rapid Prototyping Manufacturing, utilize CT and nuclear magnetic resonance (MRI)) etc. equipment acquire
The shape data at the positions such as human organ, bone, joint is rebuild three-dimensional digitalization model, is then manufactured with rapid prototyping technology
Referential model of imparting knowledge to students and perform the operation is usually used in helping to manufacture artificial limb or carries out surgical repair.But at present there has been no by this
One technology is applied to the fixed report of pedicle of vertebral arch, in addition in pedicle of vertebral arch ligamentopexis, even if preoperative produced using above-mentioned technology
The root model of pulling the bow of patient, and carried out screw into nail direction and depth simulation test, due to patient body position in operation
Variation, to accurately find simulated originally squeeze into pedicle screw into nail direction, it is difficult huge, once there is error, after
Fruit is hardly imaginable.
Currently, scientific and technical personnel's research and development both at home and abroad have relevant navigation equipment, such as Lu Sheng applications, notification number CN
101953713 B's《A kind of navigation template can be used for pedicle of vertebral arch positioning》, which can improve to a certain extent
, still, in operation there is musculature sometimes and do not clean out, lead to such channel-style guide plate in the accuracy of screw merging
It is bonded with vertebral plate not close, shifts into nail direction, however can not make adjustment, cannot be accurately set as the case may be again
Enter.
