背景技术Background technique
椎体在生长发育过程中，椎体上下面的骨骺板骨化停止后形成骨板，呈轻度凹陷，即为椎体终板。在进行椎体间植骨手术时，需要对椎体终板进行处理。传统的方法是使用骨刀或者刮匙对椎体终板进行处理，手术人员要保证处理后的椎体终板表面形成纹理，使植骨面有足够的生物力学强度，并增加植骨面接触面积。这种处理存在的隐患是：手术人员在使用刮匙时每刮取一下的力度不易掌握，手术范围以及刮除深度不易控制，容易过浅或过深，手术人员操作难度大，植骨效果不理想，容易导致手术失败。During the growth and development of the vertebral body, the ossification of the upper and lower epiphyseal plates of the vertebral body stops and forms a bone plate, which is slightly depressed, which is the end plate of the vertebral body. During intervertebral bone grafting, it is necessary to deal with the vertebral body endplate. The traditional method is to use a bone knife or a curette to treat the vertebral endplate. The operator should ensure that the surface of the treated vertebral endplate forms a texture, so that the bone graft surface has sufficient biomechanical strength and increases the contact with the bone graft surface. area. The hidden dangers of this kind of treatment are: it is difficult for the operator to grasp the strength of each scrape when using the curette, the operation range and the scraping depth are not easy to control, it is easy to be too shallow or too deep, the operation is difficult for the operator, and the bone grafting effect is not good. Ideal, it is easy to cause the operation to fail.
随着终板的处理，会积累越来越多的组织，导致术野被填满，无法查看手术的进程；为了使手术部位的视野清楚，通常需要另外采用吸引器对出血进行清理，切除刀和吸引器交替作用，操作很不方便，影响手术效率。With the treatment of the endplate, more and more tissues will accumulate, causing the surgical field to be filled, and the progress of the operation cannot be observed; in order to make the surgical site clear, it is usually necessary to use an additional suction device to clean up the bleeding, and the excision knife Alternately with the suction device, the operation is very inconvenient and affects the efficiency of the operation.
