Abstract
The invention relates to an eye surgical lighting unit for lighting internal ocular tissue. The lighting unit comprises a fiber having a proximal end and a distal end, for guiding a light beam to the distal end. The lighting unit also comprises a manual unit, provided with a cannula and a handle having an internal passage positioned in line with the cannula. The fiber is adjustable between an intraocular operational position in which the fiber extends through the internal passage of the handle and through the cannula, and a chandelier operational position in which the fiber is uncoupled from the manual unit.
Claims8
An eye surgical lighting unit for lighting internal ocular tissue comprising:
- a fiber having a proximal end and a distal end for guiding a light beam to the distal end, a manual unit provided with a cannula and a handle having an internal passage positioned in line with the cannula, wherein the fiber is adjustable between an intraocular operational position in which the fiber extends through the internal passage of the handle and through the cannula so that a desired position and/or orientation of the distal fiber end can be accurately taken up through operation of the handle, wherein, when the fiber is in the intraocular position, the lighting unit provides intraocular lighting for ophthalmic surgery, and a chandelier operational position in which the fiber is disassembled from the manual unit so that the distal end of the fiber can be introduced via a cannula of a trocar, arranged in the ocular wall, wherein, when the fiber is in the chandelier operational position, the lighting unit provides chandelier lighting for bimanual ophthalmic surgery.
A kit of parts comprising:
- a manual unit provided with a cannula and a handle having an internal passage positioned in line with the cannula;
- and
- an eye surgical lighting unit for lighting internal ocular tissue comprising:
- a fiber having a proximal end and a distal end for guiding a light beam to the distal end;
- wherein the fiber of the eye surgical unit can be inserted through the internal passage of the handle of the manual unit and though the cannula of the manual unit, such that
- if the fiber is disassembled from the manual unit, the fiber is in a chandelier operational position, the lighting unit provides chandelier lighting for bimanual ophthalmic surgery;
- and
- if the fiber extends through the internal passage of the handle of the manual unit and through the cannula of the manual unit, the fiber is in an intraocular position, the lighting unit provides intraocular lighting for ophthalmic surgery.
