Description
Technical field
The utility model relates to the field of medical instrument technology, specifically, being a kind of anterior cervical vertebrae centrum spur compound
Quantitative drawing device.
Background technique
Spur, also known as osteoproliferation are cartilages by after broken ring, perichondrium hyperplasia and the new bone that generates, through ossify
After form spur, be one of Osteoarthritis pathologic process compensation response, the spur of hyperplasia is usually at the both ends of bone four
Week exists simultaneously.
The treatment of spur can be divided into drug therapy, recovery treating, operative treatment.
Drug therapy refers to, if spur symptom is not very serious, can be used simple anodyne, anti-inflammatory drug,
Sedative etc. mitigates pain, alleviates symptom.
Recovery treating refers to, can be treated using the methods of hot compress, ultrasonic, point stimulation, head traction number.
Operative treatment refers to, when drug therapy or recovery treating 3 months or more, when being still unable to improve symptom, it is necessary into
One step imposes operative treatment.Spur or posterior longitudinal ligament ossification object still hour can carry out spur excision decompression operation, by compressing mind
The spur of warp removes, these operations include intervertebral disc of cervical vertebra resection, cervical vertebral body subtotal ectomy etc..But when spur is excessive
When, spur can not be directly cut off, spur and centrum complex can be carried out to surrounding and dissociated and (the Anterior that moves forward
Controllable antedisplacement and fusion surgery, ACAF), to release the compressing of nerve.
However in ACAF operative treatment, need the fixed lifting of centrum spur compound using surgical instrument, but now
Some surgical instruments are in operation, it may appear that firmly unevenness can not be such that spur uniform stressed lifts upwards, and cannot be quantitatively upward
Lifting, also not can guarantee spur can sufficiently expose, it is difficult to realize quantitative controllable lifting operation in art.
Chinese utility model patent CN201120081088.6, publication date 2011.11.09 disclose a kind of minimally invasive bone
Superfluous to sting cutter, including knife handle, the knife handle includes the first knife ear and the second knife ear of cross-articulation, the hand-held part of the first knife ear
Positioned at the inside of the handgrip part of the second knife ear, the top of the first knife ear is on the top of the second knife ear top position, two knife ears
