Abstract
A handheld controller for laser surgical applications includes a variable time delay control to allow a surgeon to delay interruption of laser firing in response to feedback from an overheating detector, and a detector sensitivity control for changing a sensitivity of the detector.
Claims9
A handheld controller for laser surgical applications, comprising:
- a handheld main unit including a laser;
- a fitting on said handheld main unit for connecting a fiber to said laser;
- a display;
- a feedback system for detecting overheating at a treatment site based on a parameter related to overheating and interrupting firing of said laser after a preset time interval following detection of said parameter;
- a trigger on said handheld main unit for triggering the laser to cause said firing of the laser;
- and
- a variable time delay control input on said handheld main unit to allow a surgeon to manually set said preset time interval, and thereby delay firing of said laser following detection of said parameter to provide time for a user of the controller to pull back a tip of the fiber to prevent damage to the fiber from fiber fusing or free election absorption without interrupting the firing of the laser.
