Abstract
A method and laser surgical devices for surgical incising and ablating living tissues using laser beam and effecting enhanced surgical haemostasis concurrently with incising and ablating are disclosed. The method requires a surgical laser beam that is pulsed and is highly absorbed in living tissues and enhanced haemostatic action is achieved using along with the surgical laser beam energy, delivered in pulses, another separately controlled energy effecting haemostasis, by applying the second energy in any and every given spot of incising and ablating in a preemptive and focused manner, which minimizes haemostasis-related damage to surrounding tissues. In one embodiment a heated gas jet from a hollow core optical fiber transmitting the surgical laser beam is used. In other embodiments an ancillary laser radiation at a wavelength chosen specifically to minimize haemostasis-related damage to tissue is utilized for preemptive and controlled haemostatic effect.
