  • Publication number: 20160354581
    Abstract: A torque-limiting device may include a shaft extending axially through upper and lower shanks, a spring, and a nut to an end opening of a handle. The upper and lower shanks may be under a force from the spring and further configured to selectively engage within a predetermined torque limit and disengage at above the predetermined torque limit. Accordingly, the shaft may receive torque up to the predetermined limit as provided by a user operating a handle of the torque-limiting device. The torque-limiting device may be disposable, reusable, economical, and have high torque capabilities. The shaft may be of a plastic material and include a lumen extending there through, and through which a variety of devices and materials may be delivered to a workpiece.

  • Patent number: 9504479
    Abstract: A device and method of delivering a medical tool which may be a resector, cutter, probe, or the like, including a memory arm compacted in a small diameter state which expands in a relaxed memory state, is disclosed. Said delivery may include using a hollow sheath to pre-compact or preload a memory blade into a compact position, transferring said compacted memory blade into a cannula, and deploying said memory blade from the distal end of said cannula whereby the memory blade returns to its normal expanded memory state and a deployment nut can be used to control the extension or the withdrawal of the memory arm and blade.

  • Publication number: 20160214242
    Abstract: A latch and catch arrangement is disclosed, whereby a sleeve supporting a flexible hinge with an extended finger is oriented over a fluid connection to a socket guide. An alignment via a latch and catch between the sleeve and tool collar orients a flexible hinge, which may be of reduced thickness, over a bearing in a guide. The finger moves upward when a tool is inserted into a tool socket, and the flexible hinge, properly oriented by the alignment catch/latch, keeps the finger in the tool socket while allowing necessary movement to insert and remove a tool.
