Technical Field
The utility model relates to the technical field of medical instruments, in particular to a visual vertebral body bony endplate polishing device.
Background
The intervertebral fusion for treating lumbar degenerative disease has become one of the main clinical surgical treatment methods, and in recent years, lumbar fusion is on the rise. Because the bony endplate below the cartilage endplate of the vertebra is cortical bone, the blood supply is difficult to provide for the bone implanted in the intervertebral space, so that the intervertebral bony fusion needs a long time to be achieved, and a certain non-fusion rate also exists. During the operation, the spinal surgeon needs to remove the intervertebral disc and the cartilaginous endplates on the opposite sides of the spine, fill the treated intervertebral space with bone and a fusion cage to cause bony fusion between the two adjacent vertebral bodies in order to restore the stability of the spine.
In the prior art, due to the limited operation visual field, a spinal surgeon can judge whether a bony endplate is ground to a proper state only by hand feeling when processing the endplate, and the experience of the surgeon is relied on. However, if the bony endplates are under-polished, the fusion rate is not high, and if the endplates are fractured due to over-polishing, the fusion cage may be depressed.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a visual centrum bony endplate polishing device, which can accurately control the polishing degree of a bony endplate so as to improve the fusion rate.
The utility model provides a visual centrum bony endplate grinding device, the device includes file portion, the portion of gripping and connecting portion, the both ends of connecting portion respectively with file portion and the portion of gripping fixed connection, file portion includes a file face and an installation face at least, install light source and camera on the installation face, the file face is greater than 90 with the contained angle alpha of installation face but is less than 180, connecting portion are rigid structure.
Further, in the above technical solution, the connection portion is linear.
Further, in the above technical solution, the connection portion is an L-shaped structure, and a bending portion of the connection portion is an arc.
Further, in the above technical solution, the camera is connected with a camera line, and the light source is connected with a light source line; the inside of file portion, the portion of gripping and connecting portion all is equipped with the cavity, camera line and light source line set up in the cavity.
The utility model has the beneficial effects that: dispose light source and camera, the light source can provide the illumination for the department of polishing, helps the doctor to look over the state of polishing in real time after camera and external connector are connected to a good fusion bone bed is provided. The shape of the connecting part is changed, so that the holding part and the rasping part are at different angles, and the bone end plate can be polished in all directions.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
In the following description, it is to be understood that the terms "longitudinal," "lateral," "upper," "lower," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present invention and simplicity in description, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular orientation, and thus are not to be construed as limiting the present invention. In the description of the present invention, it is to be noted that the terms "mounted" and "connected" are to be interpreted broadly unless explicitly defined or limited otherwise; the specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1
As shown in figures 1-2, a visual centrum bony endplate grinding device comprises a file grinding part 1, a holding part 2 and a connecting part 3, wherein two ends of the connecting part 3 are respectively fixedly connected with the file grinding part 1 and the holding part 2.
The rasping part 1 at least comprises a rasping surface 11 and an installation surface 12, the surface of the rasping surface 11 is in a frosted state so as to polish a bony endplate, a light source 4 and a camera 5 are installed on the installation surface 12, the rasping surface 11 is adjacent to the installation surface 12, the included angle alpha of two surfaces is larger than 90 degrees and smaller than 180 degrees, and the light source 4 and the camera 5 on the installation surface 12 do not influence polishing and can monitor the polishing condition in real time through the camera 5. In a specific embodiment, a light source wire 7 and a camera wire 6 are further arranged, one end of the light source wire 7 is connected with the light source 4, one end of the camera wire 6 is connected with the camera 5, the other end of the light source wire 7 and the other end of the camera wire 5 are both electrically connected with an external connector 8, and the external connector 8 is used for controlling the on and off of the light source 4 and the camera 5 and receiving images of the camera 6; of course, in some embodiments, the light source 4 and the camera 5 may be wireless, and connected to the external connector 8 through wireless signals. Preferably, the junction of each surface of the rasp part 1 is smoothed to avoid abrasion to other tissues at the grinding part.
