| Abstract: |
A surgical implement, such as a surgical electrode, and an ultrasound transducer, both extend through a single elongated insertion member, typically, a catheter. The ultrasound transducer extends from the proximal region of the surgical instrument containing the instrument controls toward the distal end of the catheter from which at least the operative tip of the surgical implement and the ultrasound transducer extend. In one embodiment, the catheter also contains a fiber-optic endoscope, thus allowing visual as well as ultrasound monitoring of the surgical site, before, during and after conduct of the surgical procedures. Means are provided for rotation of the ultrasound transducer to enable generation of a circular tissue reflectivity image transverse to the axis of the ultrasound transducer. Means are also provided for selective longitudinal movement of all elements contained within the catheter. Liquid crystal or other display means are provided to facilitate visual monitoring of the ultrasound and if present the endoscope outputs in real time. In embodiments including an endoscope, an optical eyepiece is provided to facilitate monitoring of its output. An ultrasound medium within the surgical site is provided by fluid inlet and removal means through the catheter.

I claim:
1. A surgical instrument having a proximal region and a distal end, comprising:
- an elongated housing extending from said proximal region to said distal end;
- a surgical implement within said elongated housing and extending from said elongated housing at said distal end, said surgical implement having an operating theater;
- an ultrasound transducer within said elongated housing and extending from said elongated housing at said distal end, said ultrasound transducer comprising:
- an ultrasound transmitter extending beyond said distal end for transmitting ultrasound waves into a region extending beyond said operating theater of said surgical implement, and
- an ultrasound microphone extending beyond said distal end for receiving ultrasound waves reflected from said region extending beyond said operating theater of said surgical implement, said ultrasound transducer generating a signal output responsive to said ultrasound microphone;
- a display to visually display said region extending beyond said operating theater of said surgical implement based on said signal output of said ultrasound microphone.
