  • Patent number: 10207045
    Abstract: A surgical handpiece has a connecting body with a distal end and a work tip with a hub at a proximal end. The hub is detachably connected to the connecting body by a threaded connector. The work tip has an open operating end at a distal end. This opening leads an axial channel extending through the work tip from the operating end to the hub. A radial channel extends from the axial channel in the hub to the external surface of the hub. A sleeve surrounds and is spaced from the hub. This sleeve extends to the vicinity of the operating end of the work tip, and has a first external connector in the region of the radial channel of the hub. The sleeve also has a second external connector. A seal is provided for establishing a fluid connection between the radial channel of the hub and the second external connector of the sleeve. The first external connector of the sleeve is in fluid connection with an irrigation channel between the inner surface of the sleeve and the external surface of the work tip.

  • Patent number: 10179068
    Abstract: A surgical hand piece has a connecting body having first and second passages detachably connected to first and second lumens which are used in the eye for phacoemulsification procedures and/or cleanup of the eye capsule after the procedure. The lumens receive or discharge fluid from first and second fluid sources. A work tip supporting the first and second tubes can be rotated so as to change the function of the first and second tubes from aspiration to irrigation and vice versa. As an alternative, a sleeve holding the fluid sources can be rotated so as to change the function of the first and second tubes from aspiration to irrigation and vice versa.

  • Patent number: 10166317
    Abstract: A surgical hand piece has a source of ultrasonic energy provided to a connecting body having a first passage with one end to receive fluid from a first source and the other end at the connecting body distal end. A work tip has first and second tubes each having at least one opening at its distal end and the proximal end of one or both of the tubes connected to the connecting body distal end to receive the ultrasonic energy and to selectively receive or discharge fluid from either the first or second source as controlled by a valve. A cannula is provided which is adapted to be placed in an opening in the cornea through which the work tip extends during the removal of cataracts from the eye by phacoemulsification. The cannula may be equipped with channels that permit additional infusion of fluid into the eye during the procedure, which infusion also cools the surrounding corneal tissue to protect against heat generated by the ultrasonic vibration of the work tip.

  • Patent number: 6358264
    Abstract: A surgical instrument includes a hollow shaft having an inner passage and a working piece at the distal end of the shaft. A movable member is pivotally mounted on the shaft in cooperative relationship to the working piece and a connecting element extends along the shaft inner passage and has one end exiting thorough an opening in said shaft and connected to the movable member. An actuating member is connected to the connecting element which upon actuation pushes and pulls on the connecting element to move the movable member toward and away from the working piece. An ultrasonic transducer can supply mechanical energy to the shaft to vibrate the working piece, the movable member is mounted to the shaft at a nodal point of the energy pattern along the shaft and the opening in the shaft for exit of the connecting element to the movable member is also at a nodal point.

  • Patent number: 6299591
    Abstract: A phacoemulsification instrument that significantly reduces infusion fluid leakage by providing a silicone sleeve with a built in reinforcing member. Also, the sleeve has only a single infusion hole in order to provide better infusion fluid flow without causing turbulence in the eye. In addition, the present invention provides either a valve or a variable aperture aspiration tube in order to regulate the aspiration rate. Also, the present invention includes a single aspiration hole at the tip in order to amplify flow coming to the tip. To assist in cataract removal, the tip may be provided with a variety of different barrier and baffle configuration. A handpiece includes a variable capacity reservoir in the infusion line to account for surges in the aspiration line. The needle includes steps, angles and barriers to focus ultrasonic energy to aid in emulsifying nuclear tissue and to aid in pushing emulsified material in the direction of aspiration flow.

  • Patent number: 5800448
    Abstract: A surgical cutting instrument is provided which includes a handpiece containing an ultrasonic transducer operative to convert electrical energy into ultrasonic longitudinal vibratory motion. A first elongate shaft has a first end operatively connected to the transducer and a second working end extending distally from the handpiece. A first cutting member is fixedly mounted to the working end of the first elongate shaft such that longitudinal vibratory motion generated by the transducer causes longitudinal vibratory motion of the first cutting member, via the first elongate shaft. A second cutting member is pivotally mounted to a nodal point on the working end of the first shaft and is pivotable between an open position and a closed position with respect to the first cutting member. A second shaft has a first end pivotally connected to the second cutting member for affecting pivotable movement of the second cutting member between the open and closed position.

  • Patent number: 5584085
    Abstract: A support arrangement is provided which has a simplified structure and is quite versatile in the support surface which is produced. The support structure includes a number of chambers or pillows which are coupled together in a sequential or serial relationship such that the air supplied to the support to inflate the chambers or pillows enters at one end and travels the length of the chamber or pillow to enter and inflate the next chamber or pillow. That is, the air supply follows a serpentine path. In this manner a simplified air supply arrangement is accomplished for the entire support structure.
