Suction tool with integrated optical probe and use thereof

A suction device for use in a medical procedure comprising:

• an elongated tip, having a hollow tubular body with a tip inner wall, a tip outer wall, a tip proximal end and a tip distal end;
• one or more channels in the tip outer wall extending from the tip proximal end to near the tip distal end;
• optical fibers within the channels;
• optical ports through the tip inner wall and extending from the channels near the tip distal end, for optical signal passage;
• a concentric ring attached to the tip, having a first end and a second end, wherein the first end is attached to the tip distal end and the first end has an inner beveled reflective surface opposing the optical ports near the tip distal end;
• an elongated tubular handle, having a central longitudinal passage, a handle proximal end and a handle distal end, the handle proximal end reversibly attached to a vacuum source and the handle distal end reversibly attached to the tip proximal end;
• a plurality of handle optical fibers embedded in the handle, extending from the handle proximal end to the handle distal end and wherein the optical fibers at the tip proximal end align with the handle optical fibers at the handle distal end;
• a light source connected to one or more of the handle optical fibers;
• and
• a spectrometer or a detector connected to one or more of the handle optical fibers.

A method for optically measuring tissue in a medical procedure, comprising:

• suctioning a tissue using a suction device, the suction device comprising a tip with optical fibers in a tip outer wall and a concentric ring attached to the tip, the concentric ring having a first end and a second end, the first end having an inner beveled reflective surface opposing the optical fibers;
• sending a first optical signal along the optical fibers in the tip outer wall through the suction device;
• directing the first optical signal from the optical fibers onto a tissue using the inner beveled reflective surface;
• directing a collected optical signal from the tissue onto the optical fibers using the inner beveled reflective surface;
• measuring the collected optical signal in a spectrometer or a detector;
• and
• releasing or resecting the tissue through the suction device.

A method for optically measuring tissue prior to ablation in a medical procedure, comprising:

• sending a first optical signal along one or more optical fibers through a suction device, the suction device comprising a tip with optical fibers in a tip outer wall and a concentric ring attached to the tip, the concentric ring having a first end and a second end, the first end having an inner beveled reflective surface opposing the optical fibers;
• directing the first optical signal from the optical fibers in the tip outer wall onto a tissue using the inner beveled reflective surface;
• directing a collected optical signal from the tissue onto the optical fibers using the inner beveled reflective surface;
• measuring the collected optical signals in a spectrometer or a detector;
• and
• ablating the tissue using an ablation optical signal along the optical fibers.
