Artificial intervertebral disk insertion jig and jig set, and artificial intervertebral disk

摘要

PROBLEM TO BE SOLVED: To provide an artificial spinal disk insertion tool excellent in operability and handleability, which easily and reliably inserts a flexible artificial spinal disk with a fiber structure as a core material between upper and lower vertebral bodies, and to provide a tool set of this insertion tool and an insertion guide tool.;SOLUTION: The artificial spinal disk insertion tool 10 is constituted by fitting a pair of upper tool 1 and lower tool 2 so as not to be separated in the vertical direction and forming an upper holding part 1a and a lower holding part 2a for holding the artificial spinal disk 3 with the fiber structure as the core material at the front parts of the upper tool 1 and lower tool 2. The artificial spinal disk insertion tool 10 holding the artificial spinal disk 3 by the upper and lower holding parts 1a and 2a are inserted between vertebral bodies from behind. Then, the upper tool 1 is pulled off and the lower tool 2 is pulled out to insert and hold the artificial spinal disk 3 between the upper and lower vertebral bodies, thereby the artificial spinal disk 3 is inserted simply and reliably. The tool set is a set of the insertion tool 10 and the insertion guide tool provided with a guide hole through which the insertion tool 10 is put and guided.;COPYRIGHT: (C)2006,JPO&NCIPI
