Description
Technical field
This utility model relates to a kind of novel cervical vertebra forming board, belongs to medical instruments field, is applicable in bone surgery.
Background technology
Cervical vertebra plate forming art is developed as a kind of alternative of laminectomy in 20 century 70s, be used for preventing laminectomy posterior spinal unstability and kyphosis deformity, existing this technology is by common cervical spondylotic myelopathy and the ossified posterior longitudinal ligament being used for the treatment of with developmental character or degenerated spinal canal stenosis, and particularly treatment relates to 3 or the cervical spinal disease of multi-segmental more.There is recently scholar also by the cervical spinal disease that causes of Adjacent segment disease after its treatment anterior cervical spine fusion, and obtain good result, this art formula can directly reduce pressure to spinal cord by increasing canalis spinalis volume, by allowing spinal cord to leave intervertebral disc and vertebral body completes indirect decompression to dorsal part migration.
The key component of cervical vertebra plate forming art is to expand canalis spinalis and maintains canalis spinalis and expands, and how to maintain vertebral plate and seem particularly important at opening position after vertebral plate opens the door, and the methods that adopt have that suture is fixed, liner is inserted with hardware and reinforced more.
Our company has researched and developed a kind of novel lamina of cervical vertebra that is applicable to laminoplasty in conjunction with domestic market.
Summary of the invention
The purpose of this utility model is: a kind of have good biocompatibility, futuramic, practical cervical vertebra forming board are provided.
The technical solution of the utility model is as follows:
This utility model is made up of flat board, bridge plate and connecting axle, it is characterized in that: this is practical two kinds of patterns, dull and stereotyped left end has a ball-and-socket hole, placement plate nail when operation, right-hand member has through hole, difference is: the first pattern is made up of two adjustable plates (1), bridge plate (2) and connecting axle (3), the low incisura of adjustable plate (1), plate body thickness is 1.6mm, right-hand member has a step with joint limit function, limited step becomes 20 ° with adjustable plate (1) plane, and two inclined-planes of limited step are in 90 ° mutually; The second pattern is made up of dull and stereotyped (4), connecting axle (3) and bridge plate (5), it is characterized in that flat board (4) and bridge plate (5) plate body thickness are 1.5mm, bridge plate (5) left end is a square connector and has a through hole, it is arch-shaped that middle part becomes, and there is a through hole its upper surface, right-hand member is three ball-and-socket holes, when operation, can optionally plate nail be implanted, facilitate operation technique.
The outer arch (bridge) type profile that forms of bridge plate (2), there are two through holes at two ends, while overlooking, bridge plate (2) across.
Connecting axle (3) is connected adjustable plate (1) with bridge plate (2), make the cervical vertebra forming board of this pattern can realize minimum 40 ° of angles, and two ends adjustable plate (1) can free adjustment;
Bridge plate (5) is made up of development axle (6) and bridge plate (7), the material that the axle (6) that it is characterized in that developing adopts is tantalum, use the development axle (6) that this kind of material made to be seated on bridge plate (5), in the time of operation, there is good development effect, can carry out nuclear magnetic resonance, NMR, facilitate postoperative inspection, connecting axle (3) has adopted tantalum material equally.
The second cervical vertebra forming board pattern of the present utility model is connected flat board (4) by connecting axle (3) with bridge plate (5), make the forming board of this kind of pattern can free adjustment, facilitates surgical selection use.
The utlity model has following advantage:
This utility model is except development axle (6) and connecting axle (3), be all to adopt polyether-ether-ketone (PEEK) material, have that temperature classification is high, radiation hardness, chemical-resistant resistance, impact strength are high, wearability and fatigue durability is good, fire-retardant, electrical property is excellent and the feature of good biocompatibility.
The design can resist the displacement of steel plate or vertebral plate, boring and screw are inserted to be all more prone to, in handled easily, can allow patient to carry out strong reconditioning, thereby reduce the incidence rate that postoperative axle symptom and motion segment are lost, realize the effect that spinal cord and bilateral nerve root fully reduce pressure.
This utility model can maintain the canalis spinalis of expansion, ensures the stable of spinal column, protects spinal column after laminoplasty; in configuration design; lever up and pre-bending to dorsal part according to vertebral plate after operation, can realize list curved and two curved, its low incisura can will drop to minimum to the stimulation of surrounding soft tissue.
This utility model adopts the adjustable project organization in joint, facilitates operation technique, and the operation scope of application is large.
This utility model structural design novelty, low incisura, operation technique is simple, has practicality, novelty and inventive features, is applicable to the use in bone surgery.
