Laser surgery controller with variable time delay and feedback detector sensitivity control

摘要

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.

主权项

1. 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.
