TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a visual endplate scraper with supporting and fixing functions. BACKGROUND
[0002] In spinal surgery, the processing of the intervertebral disc cartilage endplate is one of the key steps for the success of intervertebral fusion surgery. Moderate and sufficient processing of the intervertebral disc cartilage endplate is the key to ensure postoperative intervertebral fusion. At present, due to the deep anatomical position of the intervertebral space and the limited operation field of view, domestic and foreign orthopedic surgeons generally rely on "feel" and "experience" to process the intervertebral disc cartilage endplate using an endplate scraper. The operation cannot be performed under direct vision. High-quality endplate processing can provide a better bone contact surface for bone graft material or intervertebral fusion cages, promoting bone healing and fusion.
[0003] However, in actual surgical operation, the traditional endplate scraper is usually used for endplate cleaning. These tools have the following limitations: first, the scraping direction of the scraper is fixed, and the operation is not flexible; second, the current clinicians mainly rely on "feel" and "experience", and the operation cannot be performed under direct vision; and finally, in a narrow surgical field or minimally invasive surgery, the accuracy and efficiency of cleaning may be affected. Therefore, based on the above problems, the present application provides a visual endplate scraper with supporting and fixing functions to meet the needs. SUMMARY

[0021] By setting the bending part, the flanging part and the limiting groove cooperate, the bending part and the flanging part exist two states: when the steel sheet is straight, the bending part is unfolded, at this time the flanging part is stored in the limiting groove for fixation, the doctor inserts the scraper into the intervertebral space, the steel sheet is pressed into arc shape corresponding to the support groove, the flanging part and the bending part restore to the curved state, the structure of the bending part not only facilitates the doctor to pinch the steel sheet for adjustment, but also the outer contour of the bending part is larger than the inner wall size of the circular groove, which ensures that the steel sheet will not slip into the inside of the knife body, and further ensures the smooth operation.
