Abstract: Instrument handles isolate the functions of supporting the instrument and actuating controls on the instrument. An instrument handle may be grasped and supported by the less dexterous digits and palm of a human hand, and controls mounted on the instrument handle may be actuated by the more dexterous digits. The instrument handle may couple to an end effector so that the hand, wrist, elbow, and shoulder remain in a comfortable position when the end effector is positioned to act effectively on a selected portion of a workpiece, such as a surgical site.

Abstract: Methods of and a system for providing a visual representation of force information in a robotic surgical system. A real position of a surgical end effector is determined. A projected position of the surgical end effector if no force were applied against the end effector is also determined. Images representing the real and projected positions are output superimposed on a display. The offset between the two images provides a visual indication of a force applied to the end effector or to the kinematic chain that supports the end effector. In addition, tissue deformation information is determined and displayed.
Abstract: The present invention relates to surgical clamps and clamp devices that provide a handle-free surgical field. The clamp jaws may be opened or closed by a rotationally or translationally moveable drive element that may be actuated from a position proximal or distal to the jaws. The surgical clamps may also be deployed using a clamp applier which slidably engages the clamp along a wire to releasably attach itself to the clamp.
Abstract: The tool reduces or stops the flow of liquid or gas through a conduit and includes a crimping section, comprised of a first and second crimping member pivotally engaged with each other, and a handle section, comprised of a first and second handle member pivotally connected to each other. Each crimping member has a blunt section extending partially along an edge thereof. The first and second handle members are connected to the first and second crimping members. The conduit is crimped by applying a force to the handle members causing the handle members and the crimping members to pivot in a direction opposite each other so that the blunt sections of crimping members crimp a conduit placed therebetween thereby reducing or stopping the flow of the liquid or gas flowing through the conduit. The tool may also hold objects and be locked via separate locking mechanisms.

Abstract: Locking and releasing apparatus for operating a medical device includes a handle and a lever member coupled to the handle for grasping engagement by an operator. The lever member is moveable in opposite directions relative to the handle. A locking and release mechanism operably connects the lever member to a force transmitting member for operating the medical device at a location distant from the handle. The locking and release mechanism locks movement of the force transmitting member in one direction after movement of the lever member in a locking direction. The locking and release mechanism releases movement of the force transmitting member in the one direction after opposite movement of the lever member in a releasing direction. The lever member operates the locking and release mechanism for releasing the movement of the force transmitting member in the one direction substantially upon changing movement of the lever member from the locking to the releasing direction.
Abstract: A wire stripper has a pair of elongated frames pivotably joined together by a pivot pin and defining handles and jaws. The handles are covered by sleeves which include thumb wells which cover the ends of the pivot pin. A mechanical interlock is provided between the handles and the sleeves. The sleeves have slots for receiving the handles. The slots are offset so the front and rear surfaces of opposite sleeves are coplanar. The sleeves have a core and cushion grip overmolded on the core. A molding projection on the core allows precise placement of the core in a mold during formation of the cushion grip. A spring biases the frames to an open position. A locking member can be set by a sliding motion toward the handle end to hold the handles in a closed position. A curved shoulder on the edge of a handle wipes across a screw hole opening in the opposite jaw to provide a screw cutting function with a slicing action.

Abstract: A bottle cap remover is activated by inserting a bottle into an orifice. A detector adjacent the orifice detects the presence of the bottle and causes a linear actuator to drive a gripping device away from the top of the bottle where the cap is located. As the gripping device is moving away from the bottle cap, cam members direct hooked members of the gripping device around the bottle cap so that it is pulled off of and away from the bottle as the linear actuator drives the gripping device away from the bottle top. Once the bottle cap is removed, the linear actuator recycles to ready the bottle cap remover for the next bottle cap.
Abstract: A surgical handheld instrument which is used in a minimally invasive surgical procedure such as a laparoscopic surgical procedure comprises a handle body and an elongated shaft connected to the handle body at a proximal end of the shaft. An end effector such as a pair of movable jaws are located at the distal end of the shaft. An actuation handle member is movably connected to the handle body and is operatively connected to the end effector for actuating movement of the end effector. Thus, upon movement of the handle actuation member, the end effector, such as movable jaw elements, can be opened or closed. The handle body also includes a locking tab, having a Z-shaped configuration wherein one end of the locking tab has a hole therethrough. An arcuate locking rod having a smooth, uniform surface is connected at one end to the handle actuation member and is insertable at its opposite end through the hole of the locking tab such that the arcuate locking rod is in movable contact with the locking tab.

Abstract: There is described a stopper remover for automatically removing a stopper in a container, the remover comprising first mechanism for gripping the container against rotation, second mechanism for gripping the stopper, and a drive for rotating the second mechanism about an axis while the second mechanism grips a stopper. The remover features an engaging assembly for frictionally engaging a stopper while the rotating drive rotates in only one direction, the engaging assembly comprising an annular ring and extending from the inside of the ring, a plurality of spikes terminating in points disposed generally in an annular surface inside of the ring and constructed to engage a stopper, the spikes being mounted on the ring so as to be non-radially aligned. The result is that the spikes positively grip the stopper only if the ring is rotated in the one direction, and slip off the stopper when the rotating drive rotates in a direction opposite to the one direction.
Abstract: An improved bottle opening machine for smoothly removing crown caps from bottle necks of empty bottles contained in bottle cases which are being conveyed on a conveyance system in a single file, in which the cap removing is carried out by the steps of engaging of cap removing sections on rotary discs with the crown caps on the bottle necks in an area where the circular movement path of the cap removing sections and the linear movement path of the bottle necks mutually converge in the tangential direction, removing of the crown caps from the bottle necks under the influence of a moment which is produced as the former is separated from the latter as the rotary discs are rotated, and releasing of the removed crown caps from the cap removing sections with the aid of cap releasing mechanisms. To ensure that the cap removing sections are positioned correctly with corresponding bottle necks, at least a synchronizing means is rotatably mounted on the frame structure.
Abstract: An ampoule cutter has a pair of shells into which the tip of an ampoule may be inserted. When inserted, the neck of the ampoule is received within the V-notch of a blade carried within the cutter. The ampoule may be rotated to score the neck of the ampoule and then snapped off.
Abstract: A stopper extractor includes a housing having an open end and a closed end and a side-facing cutout on one side of the housing wall with a grip disposed for axial movement within the housing. The grip has an inwardly disposed circular flange, a side-facing cutout and an axial extension which passes through the closed housing end. The side-facing cutouts are sized to allow the enlarged head of a stopper to be inserted laterally into the grip. A crescent shaped cam is pivotally mounted to the extension and bears against the outer surface of the closed end. A handle is used to pivot the cam which pulls the grip axially upwardly. A spring, between the grip and the housing, biases the grip axially toward the open housing end. The extractor is mounted over the stopper with the open end against the container and the grip lip under the lower edge of the cork head. Rocking the handle pivots the cam to raise the grip.
Abstract: A device for controllably removing a bottle stopper from a bottle containing a liquid and natural high pressure gas, such as a sparkling wine, in which the stopper is conventionally held in place, at least in part, by a wire hood. There is a clamp for gripping the bottle adjacent the pouring lip, but free of the wire hood. There is also a clamp for gripping the stopper, which clamp will permit a loosening of the wire hood. There is a handle for applying an axial turning movement to the gripping device to torsionally remove the stopper from the bottle opening, which removal is under control and at no time will permit an uncontrolled discharge of the stopper.
