摘要:
A kind of improved Invasive lumbar fusion device and implantation instrument, Invasive lumbar fusion device can allow the operation of implantation instrument, it is implanted between two adjacent vertebras to rebuild intervertebral height, the length of Invasive lumbar fusion device main body is wide to size to the big what of size, main body length to the front end of central axis tool streamline target seeker, and tool one founds the jack-post to setting in what main body, and what jack-post outer peripheral edge is equipped with a plurality of unidirectional teeth. Implantation instrument includes a clamping bar, has in its lower end and is equipped with a plurality of unidirectional teeth in a nip part; One sliding sleeve can go here and there and cover on aforementioned clamping bar; By moving axially the sliding sleeve with respect to the what clamping bar, the closure or unlatching of the controllable nip part. The nip part of implantation instrument can clamp the jack-post of Invasive lumbar fusion device, and be intermeshed using the unidirectional tooth of the unidirectional tooth of nip part and Invasive lumbar fusion device jack-post, convertible claming angle.一種改進的椎間融合器及植入器械,椎間融合器可搭配植入器械的操作,植入相鄰的二椎骨之間以重建椎間高度,椎間融合器主體的長向尺寸大於寬向尺寸,在主體的長向中心軸線之前端具一流線型的導引頭,以及於主體內具一立向設置的軸柱,且於軸柱外周緣設有複數個單向齒。植入器械包括一夾桿,在其下端部位具一鉗口部中設有複數個單向齒;一滑套,可串套在前述夾桿上;藉由使該滑套相對於該夾桿作軸向移動,可操控該鉗口部的閉合或開啟。植入器械的鉗口部可夾持椎間融合器的軸柱,並利用鉗口部的單向齒與椎間融合器軸柱的單向齒相互嚙合,可變換夾持角度。
