Abstract
Abstract A method and apparatus for performing human and animal surgery in which the tissue field including all soft tissue fluid space interfaces can be visualized along with other soft tissue features by appropriate ultrasonic visualization means such as transmitting a scanning ultrasonic beam and receiving echoes from the desired areas and presenting a picture of said areas on a suitable display monitor such as a cathode ray tube for twodimensional presentation where the presentation may be compared with standard atlases of normal tissue. Means and apparatus for transmitting ultrasonic energy at substantially higher level than that used for visualizing the area are provided so as to selectively destroy tissue without requiring a surgical incision. The extent of the surgery may be observed with the visualizing apparatus and the surgery may be performed and monitored by the visualizing apparatus. The visualizing and the tissue destructing means are under the control of a computer which is suitably programmed for the particular operation being performed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
Apparatus for observing and diagnosing animal tissue and selectively destroying tissue comprising: a computer having first means for transmitting and scanning a focused ultrasonic beam having a relatively low energy level into said animal; said computer including means for receiving an echo of ultrasonic energy from said tissue and presenting said echo for observation or by holographic and transmission methods; said computer having means for calculating and indicating the aiming point of a focused ultrasonic beam, second means for transmitting into said animal said focused ultrasonic beam having an energy level high enough to selectively destroy cells of said animal, comprising means for scanning and focusing said first and second means on the same tissue, including alternately transmitting and scanning said tissue with said first and second means such that lesions formed by said second means are visually presented for observation.
Claim 2
Dependent Claim
141 words
Apparatus for observing and diagnosing animal tissue and selectively destroying tissue comprising: a computer having first means for transmitting and scanning a focused ultrasonic beam having a relatively low energy level into said animal; said computer including means for receiving an echo of ultrasonic energy from said tissue and presenting said echo for observation or by holographic and transmission methods; said computer having means for calculating and indicating the aiming point of a focused ultrasonic beam, second means for transmitting into said animal said focused ultrasonic beam having an energy level high enough to selectively destroy cells of said animal, comprising means for scanning and focusing said first and second means on the same tissue, including alternately transmitting and scanning said tissue with said first and second means such that lesions formed by said second means are visually presented for observation.
Claim 3
Dependent Claim
23 words
Apparatus according to claim 1 comprising means for superimposing anatomical atlases on said echoes for comparing said tissue under observation with standard tissue.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 1 including anatomical atlas information stored in said computer for presentation with the echoes of said first means.
Claim 5
Dependent Claim
44 words
Apparatus according to claim 1 wherein said first means includes a transducer for transmitting and receiving ultra sound energy from said tissue, a pulser attached to said transducer for transmitting ultra sound energy, and a receiver attached to said transducer for detecting said echoes.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 4 including a clamping circuit connected between said receiver and said transducer for preventing energy above a predetermined level from passing into said receiver.
Claim 7
Dependent Claim
15 words
Apparatus according to claim 1 comprising third means for calibrating said first and second means.
Claim 8
Dependent Claim
26 words
Apparatus according to claim 5 wherein said third means includes a thermocouple for detecting and calibrating energy in the beam of said first and second means.
Claim 9
Independent Claim
78 words
A method for performing human and animal surgery on the tissue field including focusing a low energy ultrasonic beam on a certain region of the Body, receiving with a computer producing and displaying the aiming point for a second ultrasonic beam, focusing the second ultrasonic beam for producing the surgical lesions in correct geometrical relationship with respect to the surgical field and appropriate tissues and receiving and displaying with said computer the surgical lesions as they are formed.
Claim 10
Independent Claim
78 words
A method for performing human and animal surgery on the tissue field including focusing a low energy ultrasonic beam on a certain region of the Body, receiving with a computer producing and displaying the aiming point for a second ultrasonic beam, focusing the second ultrasonic beam for producing the surgical lesions in correct geometrical relationship with respect to the surgical field and appropriate tissues and receiving and displaying with said computer the surgical lesions as they are formed.
