Abstract: A child enclosure apparatus is provided. The child enclosure is foldable between an expanded state and a compacted, collapsed state. The child enclosure may provide a plurality of scissor X-bracing interconnected by articulated corner joints that in the expanded state provides a base panel for supporting at least one child. One pair of scissor X-bracing has their two crossing members pivotally interconnected by a swing arm. The swing arm has a pivotal joint between the two crossing members, the pivotal joint and thus the swing arm is fixed when a swing locking mechanism is in a locked condition, wherein moving the swing locking mechanism to an unlocked condition allows the pivotal joint to pivot so that the swing arm and thus the scissor X-bracing may collapse into the compacted state.

Abstract: The present invention includes pin guides and methods for placing pins in adjacent vertebrae. The present invention also includes methods for placing pins in adjacent vertebrae using the pin guides described herein. The present invention also includes an intervertebral implant insertion and alignment instrument, a distraction instrument, an intervertebral implant insertion guide, and methods for inserting an implant into an intervertebral space. Despite existing tools and techniques, present positioning of implants in intervertebral spaces and pins in adjacent vertebrae often depend on a surgeon's skill, experience and technique. Practice of the present invention can aide in the placement of an implant into an intervertebral space and placement of pins in adjacent vertebrae, e.g., midline to the coronal plane spine and/or parallel to vertebral endplates that abut the intervertebral space.
