Abstract
The invention relates to a bone fragment inlayer for fracture of thoracic and lumbar vertebras. The bone fragment inlayer comprises a bone fragment inlayer body and is characterized in that the front part of the body is semicircular; the semicircular front end is flat; and the rear part of the body is provided with a handle. In use, only a part of a vertebral plate needs to be clamped and pedicle of vertebral arch and facet joint need not to be clamped during application of the bone fragment inlayer, and a dural sac and a nerve root are slightly retracted by using a nerve root retractor or nerve dissector; the inlayer is arranged along outer walls of the dural sac and a vertebral canal; a front horizontal part of the inlayer is placed in front of the dural sac; and the handle tail end of the inlayer is knocked by a bone hammer to inlay a bone fragment which enters a facet vertebral canal to cause blockage into the vertebral canal so as to relieve nerve compression. The inlayer has the advantages of simple operation, simplicity, convenience, easiness, less bleeding, slight dragging of the dural sac and the nerve root and difficult damage to nerve.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of lumbar vertebra compression fracture bone piece embeds device.
Background technology
At present, well-known, have in patient's canalis spinalis of lumbar vertebra compression fracture and block, except that fixing, also need to remove and block, remove compressing when carrying out posterior approach nerve, recover function of nervous system.But it is neural to need protection simultaneously, avoids injured nerve.Traditional method need sting except that pedicle of vertebral arch, prominent between the joint, enter along the canalis spinalis outside, will charge into intraspinal bone piece and take out, remove compressing.This method is destroyed serious, sting except that pedicle of vertebral arch, prominent between the joint, destroyed the posterior stabilization structure of vertebral body, bigger to the stability influence of spinal column, simultaneously hemorrhage more, injured nerve easily.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome the deficiency on the existing treatment technology, to provide a kind of lumbar vertebra compression fracture bone piece simple in structure, easy to use to embed device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lumbar vertebra compression fracture bone piece embeds device, and it comprises body, it is characterized in that; Described body front portion is semicircle, and semicircle front end is flat, and described body rear portion is a handle.During use, using bone piece embedding device only needs to sting except that the part vertebral plate, need not sting except that pedicle of vertebral arch, prominent between the joint, use nerve root retractor or nerve to peel off son and retract dural sac and nerve root gently, to embed device and between dural sac and canalis spinalis outer wall, put into, will embed the device front side horizontal and partly put into the dural sac front side, and use bone hammer to knock and embed device handle tail end, cause the bone piece that blocks to embed in the vertebral body in the canalis spinalis with charging into, remove compressing nerve.
The invention has the beneficial effects as follows: use this apparatus only to need to sting except that the part vertebral plate, need not sting except that pedicle of vertebral arch, prominent between the joint, destroy lessly, do not destroy the posterior stabilization structure of vertebral body, less to the stability influence of spinal column, do not need the bone piece is taken out, only need that embedding is flat forward with blocking the bone piece, simple to operate, easy, easy, simultaneously hemorrhage less, tractive to dural sac and nerve root is lighter, is not easy injured nerve.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
1. bodies among the figure, 2. semicircle, 3. front end, 4. handle.
The specific embodiment
In the drawings, a kind of lumbar vertebra compression fracture bone piece embeds device, and it comprises body 1, it is characterized in that; Described body 1 front portion is a semicircle 2, and semicircle 2 front ends 3 are flat, and described body 1 rear portion is a handle 4.
