Publication number: 20010047182Abstract: 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.Type: ApplicationFiled: November 5, 1997Publication date: November 29, 2001Inventor: WILLIAM BANKO

Patent number: 6299591Abstract: 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.Type: GrantFiled: June 19, 1998Date of Patent: October 9, 2001Assignee: Surgical Design CorporationInventor: William Banko

Patent number: 6165150Abstract: An ultrasonic instrument has a generator of ultrasonic energy and an elongated tip whose proximal end receives the ultrasonic energy from the generator which is conveyed to the tip distal end having a distal end section with an outer surface that is non-circular with a part, such as the corner junction between two walls of a polygon, having a shape to concentrate the ultrasonic energy at the tip distal end for radiation outwardly from the tip. One form of tip distal end section has a diamond shaped cross-section that can be either transverse or at an angle to the tip longitudinal axis.Type: GrantFiled: December 29, 1997Date of Patent: December 26, 2000Assignee: Surgical Design CorporationInventor: William Banko

Patent number: 5800448Abstract: 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.Type: GrantFiled: October 17, 1996Date of Patent: September 1, 1998Assignee: Surgical Design CorporationInventor: William Banko

Patent number: 5584085Abstract: 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.Type: GrantFiled: October 7, 1994Date of Patent: December 17, 1996Assignee: Surgical Design CorporationInventor: William Banko

Patent number: 4619146Abstract: A flow meter includes a piston having magnetic properties. The piston is located in a cylinder having an outlet slot. Fluid flow into the cylinder and out through the slot determines the position of the piston. The piston is preferably of a magnetic material which interacts with a Hall effect type transducer to produce an output voltage related to the position of the piston and, therefore, to the flow.Type: GrantFiled: May 22, 1981Date of Patent: October 28, 1986Assignees: William Banko, Henry E. Allen, Morris H. ShamosInventors: Tonel E. Teodorescu, William Banko
