Fluorescent handpiece

摘要

A handpiece can treat biological tissue using electromagnetic radiation, which can be substantially fluorescent light. The handpiece includes a source of electromagnetic radiation and a waveguide. The waveguide is adjacent the source, receives electromagnetic radiation from the source, and delivers the electromagnetic radiation to the biological tissue. The handpiece also includes a system for circulating a fluorescent substance through the waveguide. The fluorescent substance is capable of modulating at least one property of the electromagnetic radiation.

主权项

1. An apparatus for treating biological tissue, comprising:
a source of electromagnetic radiation, the source of electromagnetic radiation configured to generate electromagnetic radiation; a handpiece comprising a waveguide, wherein the waveguide is configured to receive the electromagnetic radiation from the source of electromagnetic radiation, the waveguide comprising:
first and second ends, and a wall extending at least partially therebetween, the wall configured to transmit the electromagnetic radiation therethrough;a passage extending along a direction between said first and second ends and configured to carry a flowable fluorescent substance; andan inlet and an outlet in fluid communication with the passage; an optical output element optically coupled to one of the first and second ends of the waveguide; and a fluid conduit in fluid communication with the waveguide's passage and configured to carry the fluorescent substance between the waveguide's passage and a fluid moving system; wherein the source of electromagnetic radiation is configured to direct the electromagnetic radiation through the wall and towards the fluorescent substance to cause the fluorescent substance to emit fluorescent light in response to the electromagnetic radiation, wherein the waveguide is configured to guide the fluorescent light emitted by the fluorescent substance towards the optical output element.
