Abstract
The utility model relates to a vertebral-plate forming steel plate, belongs to the field of medical instruments, and mainly applied to whole vertebral plate excision and decompression performed for stenosis of rear necks, chests and lumbar spinal canals. The vertebral-plate forming steel plate is composed of vertebral plate nails (1) and a vertebral plate (2). During operation, an operative incision is formed, a surgical spot is cleaned, size and number of the vertebral-plate forming steel plate needed in the operation are determined, operation is carried out, the vertebral plate (2) is implanted, a nail holding device holds the vertebral plate nails (2) which are then screwed into a spinal canal to be fixed at positions required by the operation, and the purpose of the operation is achieved.
Description
Technical field
This utility model relates to a kind of vertebral plate shaping steel plate, belongs to medical instruments field, is mainly used in way of escape neck, breast, lumbar spinal stenosis, needs the full laminectomy and decompression of row.
Background technology
General congenital (constitutional) and the posteriority (Secondary cases) of dividing of spinal canal stenosis, by the position divide that cervical spinal canal is narrow, lumbar spinal stenosis, thoracic spinal stenosis, by the region of anatomy can be divided into that central type is narrow, lateral recess stenosis, neural root hole be narrow.
Spinal stenosis refers to the narrow of various forms of canalis spinalis, nerve root canal and intervertebral foramina, comprises that vertebral canal volume that soft tissue causes changes and dural sac itself narrow.Because spinal canal stenosis causes spinal cord and nerve, thereby blood is restricted and suppress by means of administrative decrees, etc. and stimulate the generation that causes disease, this sick cardinal symptom is exactly lumbago and skelalgia.
Lumbar spinal stenosis is a kind of common disease, main pathological change at lumbar spinal stenosis, traditional Therapeutic Method is the posterior decompression operation of various ways, in order to guarantee the lasting curative effect of decompression operation, keep the spinal stability of decompression sections, the posterior decompression fusion auxiliary with internal fixation becomes the main stream approach for the treatment of lumbar spinal stenosis in recent years, though comparing with traditional method with technology, these new methods have many-sided advance, but because scale and the clinical observation limited time of its application, so academia is not reached common understanding as yet at this point.
Summary of the invention
The purpose of this utility model is: a kind of vertebral plate shaping steel plate easy to operate, novel structure that has is provided.The technical solution of the utility model is as follows:
Vertebral plate shaping steel plate is made up of vertebral plate nail (1), vertebral plate (2), it is characterized in that: vertebral plate nail (1) is for boring structural design certainly, the upper end head is made up of arcwall face and symmetrical channels, being convenient to apparatus holds and gets, nail body screw thread is pyramidal structure, and screw head has cutting edge, in the operative process, easily screws in vertebral body; Vertebral plate (2) becomes bridge-type structure, and there is sphere hole at the plate two ends, and mid portion has oblong slots.
By imaging examination before the art, determine patient's surgery location, type of surgery and implement operation: determine the degree of depth and the orientation of operation, the row surgical openings is held and is got screw, is screwed into the corresponding surgery location of vertebral body, is fixed to the requirements of operation position, realizes the operation purpose.
The glutinous company owing to canalis spinalis and attaching are not organized muscle to isolate, takes place in operation easily in the past, causes secondary to oppress, and postoperative patient produces iatrogenic antalgesic, need go second operation in case of necessity; Or adopt the imported product spinal meninges, isolate canalis spinalis and the attached tissue in back, but material compatibility is poor, and does not have the stable support effect.
The implantation of vertebral plate shaping steel plate of the present utility model is to utilize its intrinsic bridge-type profile, forms enough cavitys with the vertebral body of excision behind the vertebral plate, produces mechanicalness and stops, canalis spinalis and the attached tissue in back are effectively isolated, and avoids complication such as tissue adhesion; This steel plate adopts the manufacturing of titanium material in addition, and good biocompatibility does not reject, favourable post-operative recovery.
This utility model adopts novel project organization, and simple to operate, practical, processing cost is low, is suitable for the orthopaedics clinical application.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure chart of vertebral plate of the present utility model (2).
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Vertebral plate shaping steel plate is made up of vertebral plate nail (1), vertebral plate (2), in the operative process, the row operative incision is removed vertebral plate, the cleaning operative site, determine specification and the quantity of required vertebral plate shaping steel plate in the operation, implement operation, implant vertebral plate (2), the nail holding device tool is held and is got vertebral plate nail (1), be screwed into vertebral body, be fixed to the requirements of operation position, realize the operation purpose.
