Abstract
In a common housing are disposed an ultrasonic transmitter electrically coupled to a generator of electrical ultrasonic oscillations, and a cryodestructor communicating with a source of coolant medium. The working portion of the cryodestructor is disposed within the source of coolant medium.
Claims13
A surgical instrument for simultaneously cooling and ultrasonically irradiating tissue, comprising:
- a housing having a generally annular ultrasonic transmitter secured thereto, for generating acoustic ultrasonic vibrations in response to electrical signals of ultrasonic frequency, said ultrasonic transmitter having an end surface portion for emitting acoustic ultrasonic radiation, and a cavity within said transmitter and adjacent said end surface portion thereof;
- a cryodestructor having a working portion disposed in said cavity;
- conduit means within said housing for providing communication between a coolant medium source and said working portion of said cryodestructor;
- and
- means for coupling said ultrasonic transmitter to a generator of electrical signals of ultrasonic frequency.
