Problems solved by technology

[0008] However, in the above-mentioned known techniques 1 and 2, the rotation element (known technique 1) and the head fixing member (known technique 2), which are components for preventing the screw from retreating, are essential factors, so the disadvantage is that not only the corresponding number of components, and its structure and work become complicated, even while increasing the manufacturing cost of the cervical spine fixation device, the possibility of device failure cannot be ruled out

Abstract

An apparatus for fixing a cervical spine having a self tension part used in orthopedic surgery or neurosurgery when executing an anterior fixation operation on cervical spines is disclosed, including: an extension groove formed through a plate between the insertion holes and the center of the plate; a channel groove formed with stepped surfaces at both sides at the boundary of the insertion holes and the extension groove; a guide that is connected to the channel groove, rotates left / rightward in the channel groove and locks the screw to be inserted into the insertion holes; and a tension part that gives a pushing force the guide to be pushed toward the center of the plate and allows the guide to be rotated in the channel groove.

Description

technical field [0001] The present invention relates to a cervical spine fixation device used in orthopedic surgery or neurosurgery to perform anterior cervical spine fixation, and specifically relates to a cervical spine fixation device having a self-tensioning portion, which is formed in more than one insertion hole on a plate member. Screws are inserted in the center, wherein the cervical spine fixation device includes: an expansion hole formed through the plate element between the insertion hole and the center of the plate element; a tension portion formed inside the expansion hole to provide The center direction pushes the force of the guide part; the channel groove is formed on the boundary between the insertion hole and the expansion hole, and has stepped surfaces on both sides; the guide part is combined with the channel groove, and the The channel groove rotates left and right, and rotates back and forth according to the thrust of the tension part, so as to lock the s...
