  • Publication number: 20130305889
    Abstract: A torque-limiting driver is disclosed, having a handle, a body, a torque-limiting assembly and a work-piece engaging tip. The torque-limiting assembly includes an upper and lower shank that have a plurality of teeth circumferentially spaced. The teeth have a vertical face, an inclined face, and a flat peak. There is a spring for applying pressure across the upper and lower shank with multiple washers interposed between the lower shaft and spring. In some instances, there is a round-square drive with arched catches having preselected radii to assure operation over certain cycles at selected torque and to reduce nose cone damage and breakage at a predetermined measurement of inch-pounds of torque.

  • Publication number: 20130276597
    Abstract: A torque limiting driver with a belt driven use indicator, having a body with a shaft and tool at one end and a counter or indicator at the other end, is disclosed. The indicator is driven by a drive shaft and belt corresponding to movement of the tool. The indicator provides at least one visual cue which corresponds to a predetermined amount of use, or end of life. Alignment of the at least one visual cue with a sight or mark may be used to estimate or determine usage.

  • Publication number: 20130276598
    Abstract: A torque limiting driver with a toothed belt driven use indicator, having a body with a shaft and tool at one end and a counter or indicator at the other end, is disclosed. The indicator is driven by a drive shaft gear and a toothed belt corresponding to movement of the tool. The indicator provides at least one visual cue which corresponds to a predetermined amount of use. Alignment of the at least one visual cue with a sight or mark may be used to estimate or determine usage.

  • Publication number: 20130272786
    Abstract: According to aspects of one or more exemplary implementations, disclosed is a plastic tool mount and system with a tool connector head with a back side, nose and distal end of said nose; a shaft guide having a channel is formed within said head open at the distal end of said nose; said channel further having a raised bump section of plastic extending from a wall of said shaft guide into the shaft guide channel; and, wherein the diameter of the shaft guide channel at the location of the raised bump is diminished.

  • Publication number: 20130226182
    Abstract: A device and method of delivering a medical tool which may be a memory resector, cutter, probe, or the like, generally flat surface including a memory blade 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.

  • Publication number: 20130205569
    Abstract: A torque-limiting device may include a shaft extending axially through upper and lower shanks and a spring to connect to a nut. 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 include a lumen extending there through, and through which a variety of devices and materials may be delivered to a workpiece.

  • Publication number: 20120198972
    Abstract: A torque-limiting driver has a handle, a body, a torque-limiting assembly and a work-piece engaging tip. The torque-limiting assembly includes an upper and lower shank that have a plurality of teeth circumferentially spaced. The teeth have a vertical face, an inclined face, and a flat peak. There is a spring for applying pressure across the upper and lower shank with multiple washers interposed between the lower shaft and spring. In some instances, there is a round square drive with arched catches having preselected radii to assure operation over certain cycles at selected torque and to reduced nose cone damage and breakage at a predetermined inch pounds of torque.

  • Patent number: 7938046
    Abstract: A torque-limiting driver has a handle, a body, a torque-limiting assembly and a work-piece engaging tip. The torque-limiting assembly includes an upper and lower shank that have a plurality of teeth circumferentially spaced. The teeth have a vertical face, an inclined face and a flat peak. The inclined face is defined by a radius of curvature that transitions to the flat peak. There is a spring for applying pressure across the upper and lower shank. The teeth engage for relative rotation when the handle is turned and disengage when a predetermined value of torque is exceeded.
