Abstract: A suture cutter having a handle and a barrel with a movable cutting head on the barrel, and the barrel supporting a stationary cutting edge and a movable cutting edge. A movable support carries the movable cutting edge and includes a surface spaced from the stationary cutting edge a selected distance. An abutment wall spaced from the stationary cutting edge at the selected distance provides for snugly restricting movement of the moving cutting edge away from cutting contact with the stationary cutting edge while cutting the suture. Recesses are defined on a guiding support surface along which the movable cutting edge slides when the handle is actuated, allowing for sharpening of the moveable cutting edge when said edge is retracted proximally.

Abstract: A ratchet screwdriver having a base assembly including a handle and an insert, and having a cap rotatable on the base assembly, and there is pawl mechanism which is controlled by the cap. There is an intervening member in the form of a detent to serve as a stop for restricting the axial movement of the cap relative to the base assembly, so the cap cannot be removed from the base assembly until the detent is released. The detent, or other parts of the screwdriver, can serve as a rotation stop for the cap which has selective positions for setting the ratcheting position of the screwdriver.

Abstract: A ratcheting driver for rotationally driving a piece and having a handle and pivotal pawls engageable with a driven gear and being capable of ratcheting and driving in both rotational directions. A cap is rotatable relative to said handle and it has a web for pivoting the pawls out of engagement with the gear. Through the selective rotation of the cap, the setting of the pawls is established. A spring positions the pawls in driving positions, and the cap has surfaces which disengage the pawls from the gear upon rotation of the cap. A method of arranging the driver is included.

Abstract: A ratchet screwdriver having a base assembly including a handle and an insert, and having a can rotatable on the base assembly, and there is pawl mechanism which is controlled by the cap. There is an intervening member in the form of a detent to serve as a stop for restricting the axial movement of the cap relative to the base assembly, so the cap cannot be removed from the base assembly until the detent is released.

Abstract: A torque tool handle for releasably holding a driven shank, such as a screwdriver bit. The handle is elongated and has an opening with a sleeve therein carrying a detent and an actuator which is slidable on the sleeve for alternate locking and release of the detent relative to the shank disposed in the sleeve. There can be two handle openings at right angles to each other and with each having a sleeve and an actuator and a detent, so the handle is both an axial and a T-handle driver.

Abstract: An instrument for applying a tie (12) to two items (10, 11), and a method of making same. The instrument is arranged for pulling separated bones or other items together and securing them together by twisting a tie onto them. The instrument can be made of plastic and it need not include any threaded parts. It can have two handles (21, 22) with a tie gripper (24) and a tie guide (26) on respective ones of the handles which can be squeezed together for pulling on a tie to draw separated items together. The handles rotate together, and there can be a crank (27) for effecting the rotation and thereby twist the tie onto the items.

Abstract: A kit of medical tools for removing screws from a patient in surgical procedures, including both the kit and the method of arranging the kit and its bits and tools. There are two removable trays in a container, one for the bits and one for the tools, and the trays stack upon the other in the container. Corresponding indicia are on both the bits and the supporting trays so the bits can be organized and readily selected by the surgeon, and an abutment aligns the bits in resilient grippers on the bit tray.

Abstract: A ratchet wrench with a releasable socket which is rotatable in a handle circular pocket and the socket extends on the wrench for only the thickness of the handle and does not protrude beyond the handle. The socket is symmetrical in its configuration and is therefore reversible in its position in the pocket and it still produces the same rotational drive. A pawl and spring are on the handle, and the pawl is snug with the socket to hold the socket in an axially fixed position on the handle. The pawl protrudes from the handle and indicates the rotational drive direction required of the handle. Fluid clean-out holes extend into the pocket.

Abstract: An instrument and method for applying a suture of stiff but bendable material, such as wire, to broken bone for closing and holding the break. Also, the instrument and method are for pulling and holding two items together with a tie. The instrument has two parts movable relative to each other for pulling the items or bone together and for twisting the suture onto the bone to hold it together. The suture is strung onto the instrument on the exterior thereof without having the suture extend through the instrument interior, so the surgeon can guide the suture and accurately string it. A crank is applied to twist the suture after the suture has been initially secured to the bone to hold the bone together.

Abstract: A pliers with two handles and two jaw portions, all pivoted together. Two readable combinations, each having a scale and a pointer, are on the handles to respectively reveal the amount of pivot and the force applied to a workpiece. A parallel linkage assembly can be attached to the jaw portions for contacting the workpiece, and, because of the parallelism, the location of the contact with the workpiece is not critical to the readings.

Abstract: A screwdriver of the type having a variable torque-limiting in-line drive with a handle having a cavity and a drive bit disposed in the cavity. Over-ride drive members are disposed in the cavity and a spring exerts a force on the drive members for transmitting only a maximum force to a bit in the screwdriver. Two adjustable controls are at a back end of the tool and they are used to apply a varying force to the spring and thus limit the amount of maximum torque to be transmitted.

Abstract: A beam-type torquing and measuring tool having two telescoping members rotationally attached together at a first end of each, and they are relatively rotatable at the other end. One member transmits torque to the workpiece and has a pointer thereon, and the other member has a scale readable relative to the pointer to measure the torque being applied. The members have a central opening extending axially therethrough for canalization, and there may be adapters threadedly attached to the tool ends, and the scale and pointer can be read in their two diametrically opposite locations.

Abstract: A hand manipulated torque tool, such as a screwdriver, having two handle portions pivotal between two modes of a straight relationship and a right angle relationship which forms a T-handled tool. A lock mechanism is operative between the handle portions to releasably hold the portions in the selected modes. The mechanism is accessible from the exterior of the tool, and it is operated by user finger pressure and it automatically re-locks upon release of the pressure and the subsequent pivoting of one handle portion to either of the two positions.
