Abstract
Certain aspects of the present disclosure provide a thermally robust laser probe assembly comprising a cannula, wherein one or more optical fibers extend at least partially through the cannula for transmitting laser light from a laser source to a target location. The probe assembly further comprises a lens housed in the cannula and a protective component press-fitted to the distal end of the cannula, wherein the lens is positioned between the one or more optical fibers and the protective component.
Claims20
A probe assembly, comprising:
- a multi-core optical fiber;
- a cannula, wherein the multi-core optical fiber extends at least partially through the cannula for transmitting laser light from a laser source to a target location;
- a gradient index (GRIN) lens housed in the cannula, wherein the multi-core optical fiber touches a proximal end of the GRIN lens;
- and
- a cylindrical window press-fitted to a distal end of the cannula, wherein a distal end of the GRIN lens touches a proximal end of the cylindrical window inside the cannula, wherein a distal end of the cylindrical window extends outside the cannula, and wherein the GRIN lens is positioned between the multi-core optical fiber and the cylindrical window.
A surgical system, comprising:
- a laser source;
- a multi-core optical fiber;
- a probe assembly connected to the laser source through the multi-core optical fiber, the probe assembly comprising:
- a hand-piece connected to a cannula, the cannula comprising a distal end, wherein
- the multi-core optical fiber extends through the hand-piece and at least partially through the cannula for transmitting laser light from the laser source to a target location;
- a GRIN lens housed in the cannula, wherein the multi-core optical fiber touches a proximal end of the GRIN lens;
- and
- a cylindrical window press-fitted to the distal end of the cannula, wherein a distal end of the GRIN lens touches a proximal end of the cylindrical window inside the cannula, wherein a distal end of the cylindrical window extends outside the cannula,
- and wherein the GRIN lens is positioned between the multi-core optical fiber and the cylindrical window.
