Abstract
The present disclosure generally relates to a surgical instrument. The surgical instrument includes a base unit and a probe. The probe is disposed through an opening in a distal end of the base unit. The probe includes a port formed proximate to a distal tip of the probe. The distal tip includes a window, a lumen formed through the probe, and one or more optical fibers disposed in the lumen. The one or more optical fibers project a first laser light for irradiating an area proximate to the port to cut collagen fibers of vitreous material aspirated through the port. The one or more optical fibers further project a second laser light for cauterizing bleeding in an intraocular space of a patient.
Claims19
A surgical instrument for performing vitrectomy, comprising:
- a base unit;
- a probe coupled to a distal end of the base unit, the probe comprising:
- a distal tip disposed at a distal end of the probe, the distal tip comprising a window;
- a port formed in a side wall of the probe and proximate to the distal tip;
- a lumen formed through the probe;
- and
- one or more optical fibers disposed in the lumen, the one or more optical fibers configured to project a first laser light for irradiating an area proximate to the port, wherein the first laser light is configured to cut collagen fibers of vitreous material aspirated through the port, the one or more optical fibers further configured to project a second laser light through the window, wherein the second laser light is configured to cauterize a bleeding site;
- wherein the window is configured to allow the second laser light to pass through the window and prevent the first laser light from passing through the window.
