Patent CA-2201659-A1 (CA)
Inventor: BLACK JAMES E
IPC: F16H25/20
Filed: 1997-04-03
Abstract: An improved ball screw drive mechanism and associated method and system for controlling linear and position motion of a movably mounted carriage carrying an operative machine tool working element along a line of action within said machine tool. A threaded ball screw is stationarily non-rotatably mounted in the machine tool to extend parallel to the line of action traversed by the carriage.  A pair of threaded ball nuts are laterally restrained in and mounted for free rotation thereof in a  drive  mechanism  of  the  carriage  and  threadably  and concentrically engage the ball screw in laterally spaced apart co-axial relationship therealong. A pair of digitally controlled electric  drive  motors are  mounted  in  the  carriage  and individually operably coupled by their rotors to the ball nuts for individually imparting rotational torque to the nuts.  A conventional programmably CNC controller having single axis and slave dual motor control capability, or two axis dual motor control capability, is programmed to synchronously control both motors for causing the ball nuts to conjointly produce computer controlled linear motion and positioning of the carriage along the stationary ball screw, and to develop anti-backlash preload forces between the ball nuts relative to the ball screw.  The system can also produce an electromotive and/or  frictional braking force for decelerating and/or holding the carriage in a selected stationarily fixed position along the line of action.     The two motor rotors can exert rotational torque on the ball nuts in opposite rotary directions with the carriage moving and/or stationary.  Preload forces exerted between the ball nut can be dynamically adjusted by monitoring the load and/or position of each of the motor rotors and adjusting the power input thereto individually while producing conjoint rotary motion of the motors to drive the carriage along the ball screw. The angular phase relationship between the motor rotors and hence between the ball nuts can be controlled to vary variably the spread distance between the nuts axially of the screw within the range of system screw-to-nut backlash clearance as a function of  carriage  travel  position  and/or mode  of machine  tool operation.

Filed: 1997-05-28
Abstract: A cutting member for a medical material removal instrument comprises a cutting head having an axis and an elongate drive rod eccentrically attached at a distal end to the cutting head at a location spaced from the axis. The drive rod extends substantially parallel to the axis. The cutting member is used with an introducer sheath or catheter which has a distal end portion inserted into a patient. The cutting head is provided with a cut-out on the proximal side in part for enabling a drawing of material in a proximal direction internally from a patient into a distal end of the sheath upon a partial ejection of the cutting head from the distal end of the sheath during a material removal operation. The material drawn into the sheath is severed in a scissors-type action of the cutting head against the distal end of the sheath upon a drawing of the cutting head via the drive rod into the distal end of the sheath. The cutting head has a maximal transverse cross-section conforming in a close fit to an inner surface of the sheath and is tapered from the maximal transverse cross-section in a proximal direction to facilitate a smooth and unobstructed drawing of the cutting head into the distal end of the sheath and also without damaging the sheath. The cutting head has an at least approximately semicylindrical outer surface located between the maximal transverse cross-section and a most proximal end of the cutting head. The semicylindrical outer surface serves to ensure a locating of the drive rod eccentrically relative to the sheath upon the drawing of the cutting head into the distal end of the sheath. Irrigation is optionally provided to aid in clot removal.
