Abstract: A flexible surgical screw driver comprises a rotatable handle member, a shaft member and a flexible member. The handle member is configured with a first coupling means and the shaft member with a second coupling means. These first and second coupling means are configured to cooperate such that the handle member and the shaft member are angularly displaceable relative to each other and such that said handle member and said shaft member are non-rotatably coupled to each other for driving a screw with rotation transmitted from the handle member. The flexible member is configured to connect the handle member and the shaft member to each other and hold said handle member and said shaft member together such that the longitudinal axes thereof are substantially aligned and such that angular displacement of the handle member and the shaft member relative to each other such that the longitudinal axes thereof are misaligned, can be performed against the action of said flexible member.

Abstract: A modified power tool which includes a housing, a motive source disposed at least partially within the housing, a rigid and curved extension extending from the housing, a flexible shaft extending through the extension, and a connector assembly which includes a shaft and a connector extending from the shaft.

Abstract: A ratchet box end wrench includes a shank, a ratchet, a ring gear, three wheel members, a belt and a crank. The shank includes a space defined therein, a first pivot hole defined therein and a second pivot hole in communication with the first pivot hole. The ratchet includes a ratchet portion disposed in the space and an axial portion extended from the ratchet portion. The ring gear is connected to the axial portion of the ratchet. The first wheel member includes a pivot disposed in the first pivot hole. The belt is engaged with both of the ratchet and the first wheel member. The second wheel member is connected to the first wheel member so that the first and second wheel members are rotational together. The crank is operatively connected to the second wheel member. The third wheel member is operatively connected to the first wheel member.

Abstract: A tool has a pair of elongate housings adapted to be joined together in a housing assembly for enclosing and supporting a flexible drive mechanism entrained about a pair of rotatable elements. Each of the rotatable elements is disposed on the housing assembly at opposite ends thereof. A flexible drive mechanism provides a transfer of power between the rotatable elements so that rotation of one rotatable element at one input end of the housing assembly will effect driven rotation of the other rotatable element at an output end of the housing assembly. The elongate housings include male and female configurations for aligning and joining the housings without independent fasteners.

Abstract: A powered wrench includes a chain that is driven by a fluid motor. The chain engages a workpiece and rotates that workpiece in response to operation of the fluid motor. The fluid motor can be located spaced from the handle of the wrench or in the handle of the wrench. An extension can also be included to extend the reach of the wrench.

Abstract: Manual bone anchor placement devices include a lever, a force translator and a rotary force mechanism. The devices are substantially gun- or pistol-shaped and are actuated when a user squeezes the lever to the gripping portion of a handle. Manual, linear force on the lever is mechanically translated through the force translator to the rotary force mechanism which transmits a rotary force to a securing element, or coupler, which mates with a bone anchor screw. The rotation of the securing element or coupler applies a torque on the bone anchor screw thereby placing the screw into bone. Kits comprising any of: a molded flexible sleeve for enclosing a suture, a retaining clip for preventing the suture from slipping out of the sleeve, a buttress-shaped bone anchor screw comprising a micropolished eyelet for receiving a suture, and a suture which may, or may not be pre-attached to the bone anchor screw, are disclosed. A collapsible, protective cover for a bone anchor screw is also disclosed.

Abstract: A torque transfer device allows torque to be input at one point of the device and transferred to another point of the device, at which the power or torque is taken from the device. The device incorporates a continuous direct drive comprised of a plurality of individual, and unconnected, pins which advance each other to provide the drive. The pins have enlarged ends and reduced centers. The centers of the pins ride on a centrally disposed shedder which acts as a guide rail. The direct drive communicates with the drive sprockets, traveling through the drive sprockets to rotate the drive sprockets to transfer torque.
