Abstract
An annular spinal rongeur applied to a subtotal laminectomy preserving a posterior ligamentous complex of a lumbar vertebra comprises two symmetrical work arms hinged via a rotary shaft, each work arm includes a work end and a handle connected fixedly and integrally, both the two work ends are provided with ribbing rings integrated with the work arms structurally, and each ribbing ring is in an integral annular structure while the ribbing rings are in symmetrical arrangement. The annular spinal rongeur has the advantages that in application of the subtotal laminectomy preserving the posterior ligamentous complex of the lumbar vertebra, the ribbing rings are placed at a root position with corresponding spinous processes to be cut, after the handles are pressed by force, opposite edges of a spinous process, part of interspinal ligament and part of vertebral plates are cut off, and then partial cutting and spinal canal decompression of bilateral vertebral plates are carried out. Therefore, the annular spinal rongeur is simple in operation and standard and accurate in position, and saves time and labor for the subtotal laminectomy preserving the posterior ligamentous complex of the lumbar vertebra.
Description
Technical field
This utility model relates to the rongeur of using in a kind of vertebral plate subtotal ectomy, particularly a kind of ring-type spinal rongeur that uses in the vertebral plate subtotal ectomy that keeps lumbar vertebra rear ligament complex.
Background technology
At present, when lumbar spinal stenosis patient row was kept the vertebral plate subtotal ectomy of rear ligament complex, the excision of relative edge of spinous process root and part interspinal ligaments mainly was that the little osteotome of utilization cuts to sting with laminectomy rongeur and removes, time-consuming, effort, and position and the difficult grasp of scope.
Summary of the invention
This utility model is at the deficiencies in the prior art, provides a kind of operating position accurate, time saving and energy saving ring-type spinal rongeur.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of ring-type spinal rongeur, comprise two with the hinged symmetric working arm of rotating shaft, each working arm includes working end and the handle that fixes as one, described two working ends are provided with the bone biting ring that is structure as a whole with it, described bone biting ring entire body is structure in the form of a ring, and is oppositely arranged.
Compare with current methods, the beneficial effects of the utility model are: when time full resection operation of the vertebral plate that implement to keep rear ligament complex, bone biting ring is placed on the root position of intending the relative spinous process of excision, handle firmly, the relative edge of spinous process and part interspinal ligaments and part vertebral plate stung remove, and then carry out the part excision and the spinal canal decompression of both sides vertebral plate.Therefore, this utility model is simple to operate, time saving and energy saving when time full resection operation of the vertebral plate that implement to keep rear ligament complex, location specification is accurate.
Description of drawings
Fig. 1 is this utility model overall structure sketch map.
Fig. 2 is the cutaway view of bone biting ring.
Among the figure: bone biting ring 1, rotating shaft 2, handle 3, working end 4, through hole 5.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, in the present embodiment, this ring-type spinal rongeur, comprise two with the hinged symmetric working arm of rotating shaft 2, each working arm includes working end 4 and the handle 3 that fixes as one, two working ends 4 are provided with the bone biting ring 1 that is structure as a whole with it, and the entire body of bone biting ring 1 is structure in the form of a ring, and is oppositely arranged.Through hole 5 equal diameters in bone biting ring 1 centre.
Using method of the present utility model is:, the vertebral plate subtotal ectomy that keeps rear ligament complex with lumbar spinal stenosis patient row is an example, operating process is summarized as follows:
The patient ventricumbent position, median incision behind the back successively cuts skin, subcutaneous, fascia, and spinous process is other peels off sacrum ridge flesh, appears spinous process, vertebral plate, the articular process of intending the decompression sections.At first excise ligamenta flava between the vertebral plate of relief space, appear clear and the separately adhesion between dura mater and vertebral plate.The bone biting ring 1 of ring-type spinal rongeur front end is placed the relative edge of spinous process of intending excision, firmly clutch handle 3, two bone biting rings, 1 relative motion, sting and remove part spinous process root, interspinal ligaments, part vertebral plate, keep supraspinal ligament, part interspinal ligaments, spinous process root, sting remove in, sting the broken bone removed and drop out by the through hole 5 at bone biting ring 1 center.Carry out the excision of the relative edge of vertebral plate with osteotome or laminectomy rongeur then and vertebral plate subtotal ectomy and/or side crypts decompression are finished in the excision of articular process inner edge.
Claims (1)
1. ring-type spinal rongeur, comprise two with the hinged symmetric working arm of rotating shaft, each working arm includes working end and the handle that fixes as one, it is characterized in that, described two working ends are provided with the bone biting ring that is structure as a whole with it, described bone biting ring entire body is structure in the form of a ring, and is oppositely arranged.
