Assignee:
TYCO Healthcare Group LP - Boulder CO
International Classification:
A61B 17/32
US Classification:
606169
Abstract:
The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.

International Classification:
A61B 17/295
US Classification:
606169
Abstract:
An ultrasonic surgical instrument is provided. The ultrasonic surgical instrument includes a housing having an elongated shaft extending therefrom. The shaft has a jaw member disposed at a distal end thereof. The jaw member is movable between an open configuration and a clamping configuration and includes a tissue contacting surface thereon. A cutting blade extends from a distal end of the shaft and operably couples to the housing and adjacent the jaw member to treat tissue. A selectively removable laminate liner is positionable over the tissue contacting surface of the jaw member and configured to prevent contact between the tissue contacting surface and the cutting blade when the cutting blade is treating tissue.
Electrosurgical System Having A Sensor For Monitoring Smoke Or Aerosols
US Patent:
8235982, Aug 7, 2012
Filed:
Sep 19, 2008
Appl. No.:
12/233894
Inventors:
Arlen K. Ward - Thornton CO, US
Assignee:
TYCO Healthcare Group LP - Mansfield MA
International Classification:
A61B 18/04
US Classification:
606 34, 604 23
Abstract:
An electrosurgical system includes an evacuator apparatus and a sensor. The evacuator apparatus evacuates aerosol and smoke generated during application of electrosurgical energy. The sensor is operatively coupled to the evacuator apparatus and senses the aerosol and smoke generated during application of the electrosurgical energy. The sensor generates data in response to the sensed aerosol and smoke. The sensor operatively communicates the data to the evacuator apparatus and the evacuator apparatus evacuates the aerosol and smoke as a function of the data.
