CONNECTOR FOR SECURING ULTRASOUND CATHETER TO TRANSDUCER |
摘要 |
An ultrasound system has an ultrasound transducer having a transducer housing and a horn provided at the distal end of the transducer housing, an ultrasound transmission member, a sonic connector that is connected to the horn and the proximal end of the ultrasound transmission member, and a catheter knob having a proximal end that is coupled to the distal end of the transducer housing. The catheter knob has a proximal bore that houses the sonic connector. The system also includes a nesting piece that is retained inside the proximal bore of the catheter knob. The nesting piece can be moved from a first position where the sonic connector is received inside the nesting piece to a second position where the sonic connector is separated from the nesting piece when ultrasound energy is being propagated through the ultrasound transmission member. |

1. A system comprising:
an ultrasound transducer housing containing a transducer horn that is connected to a signal generator; a transducer mechanism comprising a slide collar assembly that comprises an outer ring that is disposed around an inner ring having a longitudinal through a wall of the inner ring; and a catheter having:
a flexible body;a proximal end;a distal end;at least one longitudinal lumen;an ultrasound transmission member having a proximal end and disposed in the lumen;a connector joining the proximal end of the ultrasound transmission member and the transducer horn;a knob having a proximal end that is coupled to the distal end of the transducer housing, the knob having a proximal bore that houses the connector;anda nesting piece that is retained inside proximal bore of the knob, the nesting piece movable from a first position where the connector is received inside the nesting piece to a second position where the connector is separated from the nesting piece. |
