AI Technical Summary

Benefits of technology

The locking mechanism effectively prevents screw backout and rotation, providing secure fixation while allowing easy positioning and implantation, reducing hardware failure and simplifying the fitting process, thereby enhancing the stability and reliability of the bone fixation system.

Problems solved by technology

The locking device physically impedes the top of the screw from rising, which prevents the screw from rotating (as this would cause the screw to rise).

Embodiment Construction

[0056]The technology relates to a device for locking a bone fastening or fixation mechanism in a receiving member of a medical implant. The bone fastening or fixation mechanism is used to mount the receiving member to a bone structure in the medical implant. The locking mechanism prevents the bone fastening mechanism for backing out of the receiving member. A retention mechanism is used to controllable move and retain the locking mechanism in the locked (closed) or unlocked (open) position.

[0057]Referring to the figures, FIG. 1A is a top view of an embodiment of the present invention showing a cervical plate 100 with the locking mechanism 101 in the unlocked position. The locking mechanism 101 has a rotating blocker cover 701 (shown in more detail in FIGS. 7A-7D discussed below) that can be rotated to partially cover holes (bone screw holes) 102 and 103. (The holes are also referred to as “fastener openings”) As shown in FIG. 1A, the locking mechanism 101 is in the unlocked (otherwi...

Abstract

A device for locking a bone fastening or fixation mechanism in a receiving member of a medical implant. The locking mechanism is kept in place (both in its locked and unlocked positions) using a retaining mechanism. The retaining mechanism also provides predetermined locked and unlocked positions that are readily moved to by the practitioner and maintained in position once placed there.

Description

RELATED APPLICATIONS[0001]This application is related to U.S. patent application Ser. No. ______, (Attorney Docket No. 156238.000201), filed concurrent herewith, entitled “Locking Device For Fixation Mechanism Of Medical Implant.” This application is commonly assigned to the Assignee of the present invention and is hereby incorporated herein by reference in their entirety for all purposes.FIELD OF INVENTION[0002]A device for locking a bone fastening or fixation mechanism in a receiving member of a medical implant.BACKGROUND OF INVENTION[0003]The spine is the axis of the skeleton on which all of the body parts hang. In humans, the normal spine has seven cervical, twelve thoracic and five lumbar segments. The lumbar spine sits upon the sacrum, which then attaches to the pelvis, and in turn is supported by the hip and leg bones. The bony vertebral bodies of the spine are separated by intervertebral discs, which act as joints but allow known degrees of flexion, extension, lateral bendin...
