Abstract

An energy-based surgical system includes a light beam source and a probe. The light beam source is configured to selectively provide a beam of light. The probe defines a channel about a longitudinal axis thereof and a side opening near a distal end thereof. The channel is operatively connected to the light beam source and is configured to transmit the beam of light from the side opening. The beam of light is configured to detect the presence of a nerve within targeted tissue. The probe may further be configured apply treatment energy to tissue to treat tissue.

Claims

1. An energy-based surgical system comprising:

a light beam source configured to selectively provide a beam of light;

a probe defining a side opening near a distal end thereof;

a feedline disposed within the probe, the feedline configured to deliver electrosurgical energy to the probe, the probe configured to supply the electrosurgical energy to tissue to treat tissue, the feedline defining a channel along a longitudinal axis thereof which extends through the probe and is communication with the side opening, the channel operatively connected to the light beam source and configured to transmit the beam of light from the side opening of the probe; and

a fiber optic cable disposed within the channel, the fiber optic cable operatively connected to the light beam source to transmit the beam of light from the light beam source through the side opening, the distal end of the fiber optic cable being angled to direct the beam of light through the side opening.

2. The system of claim 1, wherein the beam of light has a wavelength in a range of 10 nm to 1 mm.

3. The system of claim 1, further including an expandable member, a portion of the probe disposed within the expandable member.

4. The system of claim 3, wherein the expandable member is transparent to the beam of light.

5. The system of claim 1, further including a treatment energy source, the and a feedline operatively connected to the treatment energy source.

6. The system of claim 5, wherein the treatment energy is electrical energy having a frequency in a range of 500 MHz to 2500 MHz.

7. The system of claim 5, wherein the treatment energy is electrical energy having a frequency in a range of about 500 MHz to about 10 GHz.

8. The system of claim 1, wherein the light beam source is configured to provide a beam of light that stimulates a nerve disposed within tissue to generate a physiological response.

9. The system of claim 1, further comprising a source of electrosurgical energy, the feedline in electrical communication with the source of electrosurgical energy.

10. An energy-based surgical device comprising:

a feedline defining a proximal portion of a channel about a longitudinal axis thereof;

a probe defining a distal portion of a channel about a longitudinal axis thereof and a side opening near a distal end thereof, the channel configured to transmit a beam of light from a light beam source through the side opening, the probe configured to treat tissue with electrosurgical energy received from the feedline; and

a fiber optic cable disposed within the channel and operatively connected to the light beam source, the fiber optic cable having an angled distal end configured to redirect the beam of light at an angle relative to a longitudinal axis of the fiber optic cable such that the beam of light is transmitted through the side opening.

11. The device of claim 10, further including an expandable member, a portion of the probe disposed within the expandable member.

12. The device of claim 11, wherein the expandable member is transparent to the beam of light.

13. The device of claim 10, wherein the probe includes an antenna disposed therein, the antenna operably connected to an electrosurgical energy source by the feedline and configured to radiate treatment energy to tissue to treat tissue.
