Abstract
The utility model relates to a vertebral column processus spinosus retainer for treating vertebral column disease. The vertebral column processus spinosus retainer comprises a main clamping plate, anauxiliary clamping plate and a sheath. The vertebral column processus spinosus retainer is characterized in that the working bearing surface of the retainer is H-shaped, the sheath is arranged betweenthe main clamping plate and the auxiliary clamping plate, the sheath can also be designed into a whole with the auxiliary clamping plate, and the main clamping plate and the auxiliary clamping platehave an embedded connection structure. When in use, a hole is drilled on the pathologic vertebral column, the auxiliary clamping plate cylinder provided with the sheath penetrates the vertebral columnhole, and the front part of the auxiliary clamping plate cylinder extending out is embedded into the main clamping plate, so that the main clamping plate and the auxiliary clamping plate can be connected into a whole; the working bearing surface of the retainer is H-shaped, so as to fix the upper part and the lower part of the vertebral column, so that the pathologic vertebral column can not be affected by the motion of the body.
Description
Technical field
This utility model is a kind of medical apparatus, particularly relates to a kind of spinous process keeper of the human spine's of treatment disease.
Background technology
In the field that spinal surgery is learned, the method of using internal fixation has had quite long history at home and abroad, method that is adopted and internal fixation apparatus are various, but since the form difference of various internal fixation utensils, the structure difference, all has very high specificity again, its certain limitation is all arranged in practical clinical, and the operation technique difficulty is complicated, and the operation wound mouth is more, steadiness deficiency, and the loosening slippage that has a postoperative apparatus common complication such as fracture.
Summary of the invention
The purpose of this utility model is to provide a kind of material property stable, does not produce loosening and slippage, the spinous process keeper of not soft tissue injury, and facilitating operation.
The purpose of this utility model is achieved in that a kind of spinous process keeper, comprise bottom plate, inferior clamping plate and sheath, it is characterized in that: the work supporting surface of spinous process keeper is " worker " font, between bottom plate and time clamping plate, be provided with sheath, sheath can be an one with inferior cleat design also, and bottom plate is embedded syndeton with time clamping plate.
The siamese part that described bottom plate is made up of torus separated, that hole wall is provided with pair of keys in an oval ring body of passive long narrow shape and one interconnect function, the centre bore on this siamese part is a springhole, during normality: the aperture is D

The material of described bottom plate, inferior clamping plate, sheath is: PEEK or titanium alloy or silica gel.
During use, on the pathological changes spinal column, punch, the inferior clamping plate cylinder of grip upper jacket penetrates in the spinal column hole, the cylindrical front portion of inferior clamping plate that to stretch out, embed in the bottom plate, bottom plate fuses with time clamping plate like this, and its work supporting surface is " worker " font, it makes this part pathological changes spinal column not be subjected to the influence of human motion the spinal fixation of upper and lower part.
The beneficial effect that this utility model produces is: following disease is had excellent curative: 1, the caused unstable spine of spinal trauma is fixed, as the slippage of the fracture and the vertebral body articular process of spinal column.2, scoliosis is orthopedic fixing.3, the unstable spine due to the spinal operation.4, the unstable spine due to the regression in lumbar vertebra and little joint, slippage is fixed etc.This utility model is not only simple in structure, and volume is little, and operation technique is convenient.
