  • Patent number: 8683896
    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: 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.

  • Patent number: 5934160
    Abstract: A device for removing a cork from a stoppered bottle utilizes a lever and a cam to drive a helical corkscrew into a cork, to withdraw the cork, and then to strip the cork from the corkscrew. The device comprises a housing having a bell-shaped opening to be placed over the mouth of the bottle. A lever has a semi-circular gear at one end which is pivotally joined to the housing. The gear engages a reciprocating, and preferably a rotatable gear rack whereby pivotal movement of the lever causes the gear rack to move linearly up and down through the housing. The lower end of the gear rack is joined to the corkscrew the free end of which extends through a cam collar and engages a cam follower therein. The cam collar is movable vertically within the housing from a lower position to a raised position, but is restricted against rotation relative to the housing. Two or more flexible fingers have notches therein which engage and disengage corresponding projections on the cam collar.

  • Patent number: 5924338
    Abstract: Apparatus comprising a worm (14) that engages with a control nut (9), such that the worm spirals through the nut into the cork (4) on insertion while the nut remains stationary, then the cork is extracted by an upward force on the nut. Mechanical advantage may feature on the insertion and/or extraction processes. Both the upward force and the torque on the worm from the nut are balanced by non-frictional forces from the cork, arising from frictional forces between the bottle (2) and the cork. Having independent insertion and extraction mechanisms enables these mechanisms to be controlled independently and enables the worm to be inserted to and extracted from different depths, depending on the length of the cork. This is not possible in previous nut corkscrews, which rely either on latches at the end of the insertion stroke or on friction between the cork and the worm.

  • Patent number: 5020395
    Abstract: Stopper removal apparatus of the type in which gas under pressure is directed into a container thereby to eject a cork or like stopper. The apparatus directs gas from a gas cylinder into a gas reservoir sealed by a piston valve. Each gas cylinder has its own seal to prevent gas escaping during storage. As a new cylinder is installed and the cylinder seal is broken, the resulting gas from the cylinder forces the piston valve to its sealing position, so no gas escapes. The gas pressure provides the sealing force. When an actuator moves the piston valve to an open position, gas passes through passages and a hollow needle that penetrates the stopper to exit within the container to eject the stopper.A cover assembly completely encloses the needle. A disk at one end of the cover retracts as the needle is inserted into the stopper. After the stopper is ejected it remains on the needle within the cover.

A first handle piece has one or more arc-like slots which criss-cross with one or more slots in a second handle piece. A third piece called a jaw piece has a vertical slot that is coextensive with the other two slots. A locking pin is movably positioned in and through the three slots. When pressure is exerted upon the two handle pieces, this locking pin is tilted against the walls of the slots to lock the jaws of the tool in position. When pressure is exerted on the handles, the slots can leverage the pin both rotationally and radially. Resistance to the pin movement either radial or rotational causes the pin to be tilted against the walls of the slot in such positions as to preclude natural reversed movement of the pin as in a one-way valve.

  • Patent number: 4947711
    Abstract: A device for the controlled removal and re-insertion of the cork used with the conventional champagne bottle. The device has a first member having a cavity which is sized and shaped to straddle the neck of the bottle, with a plastic insert to specifically fit the circumferential rib which the conventional champagne bottle has near the spout. A second member contains annular ridges to slide onto and grip the head of the cork. A single handle utilizes a rack gear mechanism to move the two members apart, linearly and under leverage, so that the cork can be removed and re-inserted with ease.

  • Patent number: 4765206
    Abstract: A cork extractor for a cork in a bottle has a frame adapted to engage the bottle end around the axis of the cork and has a rod slidable and rotatable in the frame in line with the cork. A lever pivoted on the frame has a yielding pawl adapted individually to engage and successively to ride over each one of a series of stops on the rod, in this way incrementally extracting the cork with each actuation of the lever.

  • Patent number: 4750391
    Abstract: An opener (10) for removing a cork (36) from a champagne-type bottle (12)in a generally straight line comprises a frame (20, 22) contactable with the bottle by a pivotable annulus (60) so that the opener can be maintained generally immobile with respect to the bottle during removal of the cork. A pair of tongs (32) are slidable in channels within arms (30) so that the tongs may be moved towards and from the mouth of the bottle. The tongs are pivotable with respect to one another so that, when they are moved upwardly from the mouth of the bottle by a rack (46) engaging gear segments (50) on handles (54), the tongs can pivot towards one another to secure better engagement with the cork to effect movement of the tongs and the cork engaged thereby in a direction away from the bottle. The tongs are also pivotable to accommodate corks of different sizes, and the wires binding the cork to the bottle.

  • Patent number: 4703673
    Abstract: Apparatus for extracting a cork from a bottle comprises a movable portion, a handle, and a holder. The movable portion includes a helical corkscrew. The handle includes at least one elongate arm and is associated with the movable portion such that the arm may extend radially outwardly with respect to the corkscrew in an operating position of the handle. The arm has a restraining formation disposed distal the corkscrew in the operating position and adapted to engage a human finger and restrain it against movement radially outwardly. The holder is engageable with a bottle and defines an opening for receipt of a cork as it emerges from the bottle. The holder has a guide which allows rotational and longitudinal movement of the movable portion relative to the holder whereby the corkscrew can be driven downwardly into the cork and to a lowered position with respect to the holder upon rotation of the movable portion in a first direction.
