Abstract
A laser probe including an optical fiber for guiding a laser beam, a holder fixed at an end portion of the optical fiber, and a reflection tip detachably attached to the holder and having a reflection surface for reflecting the laser beam emitted from the optical fiber.
Claims39
A laser probe comprising:
- an optical fiber for guiding a laser beam;
- a tube in which the optical fiber is inserted;
- a holder for fixing the optical fiber and an end portion of the tube where the laser beam is emitted;
- and
- a reflection tip detachably attached to the holder and having a reflection surface for reflecting the laser beam emitted from the optical fiber, the reflection surface reflecting the laser beam along a laser optical path;
- and
- a lens positioned in said reflection tip between said optical fiber and said reflection surface, and in a path of said laser beam as it is emitted from said optical fiber;
- wherein:
- said holder includes a slit portion,
- a cooling fluid passage is defined by a space between the optical fiber and the tube, and
- the cooling fluid passage extends through the slit portion of said holder, through said space, and opens at an emission end portion of the optical fiber in the vicinity of the reflection surface of the reflection tip, such that cooling fluid flows through said fluid passage to contact said reflection surface, and flows along the laser optical path after contacting the reflection surface, whereby said cooling fluid passage communicates a fluid to outside of the reflection tip.
