Abstract
A device for internal ultrasound procedures includes a motor which rotates a drive shaft and an ultrasound transducer. A gearing assembly provides reciprocating rotational motion from a unidirectional motor. A cam assembly provides reciprocating pivotal motion to the transducer. Conductors can attach to the transducer and extend through the drive shaft.
Claims28
A medical device, comprising:
- a unidirectional rotary motor;
- a bidirectional ultrasound transducer;
- and
- a unidirectional-to-bidirectional gearing assembly operatively disposed between the motor and the transducer.
1 more element
A medical device, comprising:
- a first motor operatively coupled with a first drive shaft, wherein the first drive shaft extends substantially along a rotation axis, wherein operation of the first motor rotates the first drive shaft about the rotation axis;
- a transducer configured for transmitting and/or receiving ultrasound signals, wherein the transducer is disposed to move about a pivot axis which is substantially perpendicular to the rotation axis;
- and
- wherein the first drive shaft includes a cam surface disposed to impart pivotal motion to the transducer when the first drive shaft rotates.
1 more element
A medical device comprising:
- a transducer configured for transmitting and/or receiving ultrasound signals;
- a first motor operatively disposed to impart movement to the transducer about a pivot axis which is substantially perpendicular to a rotation axis;
- a second motor operatively disposed to impart rotational motion to the transducer about the rotation axis;
- and
- wherein the speed of movement of the transducer about the pivot axis is determined by a difference between the rotational speed of the first motor and the rotational speed of the second motor.
