    摘要： An electrosurgical instrument is provided and includes a housing configured to connect to a source of bipolar electrosurgical energy and an electrode body coupled to the elongated housing. The electrode body includes an electrode face, first and second bipolar electrodes and a blade. The electrode face is formed on the distal end of the electrode body and includes a longitudinal axis and a transverse axis therethrough. The first and second electrodes have a leading edge and a trailing edge, are formed on opposite sides of the longitudinal axis and connect to opposed electrical potentials. The blade is positioned between the electrodes with at least a portion of the blade extending beyond the electrode face.

    摘要： A system for light based interrogation of a lung includes a memory, an electromagnetic (EM) board, an extended working channel (EWC), an EM sensor, a light source, a light receptor and a processor. The memory stores a 3D model and a pathway plan of a luminal network and the EM board generates an EM field. The EWC navigates a luminal network of a patient toward a target in accordance with the pathway plan and the EM sensor extends distally from a distal end of the EWC and is configured to sense the EM field. The light source is located at or around the EWC and emits light, and the light receptor is located at or around the EWC and is configured to sense reflected light from airway of the luminal network. The processor converts the reflected light into light based data and identifies a type or density of tissue.

    摘要： A system for use with a microwave antenna includes a microwave antenna configured to deliver microwave energy from a power source to tissue and a sensor module in operative communication with the power source and configured to detect a reflectance parameter. The system further includes a jacket adapted to at least partially surround the microwave antenna to define a fluid channel between the jacket and the microwave antenna. A plurality of fluid distribution ports are defined through the jacket and are in fluid communication with the fluid channel to permit the flow of fluid through the jacket. The system further includes a fluid pumping system operably coupled to the power source and configured to selectively provide cooling fluid to the fluid channel for distribution through the fluid distribution ports based on the reflectance parameter.

    摘要： A system for ultrasound interrogation of a lung including a memory, an electromagnetic (EM) board, an extended working channel (EWC), an EM sensor, a US transducer, and a processor. The memory stores a three dimensional (3D) model and pathway plan for navigating a luminal network. The EM board generates an EM field. The EWC is configured to navigate the luminal network toward a target following the pathway plan. The EM sensor extends distally from a distal end of the EWC and is configured to sense the EM field. The US transducer extends distally from a distal end of the EWC, generates US waves, and receives US waves reflected from the luminal network. The processor processes the sensed EM field to synchronize a location of the EM sensor in the 3D model, to process the reflected US waves to generate images, or to integrate the generated images with the 3D model.
