International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

A locking device for locking an expandable support device, where the locking device includes a spring device integral with the expandable support device, and the spring device includes an end portion, a first flexible arm, and a second flexible arm. A first aperture of the spring device is adapted to position the fastener associated with the first rotational position and a second aperture of the spring device is adapted to position the fastener associated with the second rotational position. The first flexible arm and second flexible arm are adapted to flex outward and allow passage of the fastener head when an inward pressure is applied to the fastener positioned in the second aperture. The first flexible arm and the second flexible arms are adapted to collapse to their unflexed position after the fastener head has completed passage through the spring device, such that the first flexible arm and the second flexible arm are adapted to cover the fastener head and prevent the fastener from backing out.

International Classification:

A61B 17/70

US Classification:

606266

Abstract:

A spinal fixation system comprising at least one fastener having a fastener head at a proximal end and at least one body. The body comprises a rod receiving channel for receiving a fixation rod, a pressure cap for engaging the fastener head, and a fastener head receiving chamber for retaining the fastener head within the body. The fastener head receiving chamber allows for multi-axial movement of the body in relation to the fastener when the pressure cap is disengaged from the fastener head. The body is secured in a mono-axial position in relation to the fastener when the pressure cap is biased against the fastener head.

- Lewisville TX, US
Nelson Li - Hillsdale NJ, US

International Classification:

A61B 17/17

US Classification:

606 96

Abstract:

The embodiments described and claimed herein relate to a locking assembly including a locking member adapted to set a maximum drilling depth for a drill bit, wherein the drill bit is adapted to extend through a drill bit guide. In one embodiment, the locking member includes a housing and a first inner sleeve, wherein the first inner sleeve has a resting unbiased position with respect to the drill bit guide. The locking member includes a first biasing member having a first end adapted to connect to a portion of the housing, and a second end adapted to connect to a portion of the first inner sleeve, wherein the first inner sleeve is resiliently rotatable to a temporary biased position upon rotation of the housing such that the first inner sleeve is adapted to rotate a circumferential distance with respect to the drill bit guide.
