ABSTRACT
Wound healing is the process by which skin or other body tissue repairs itself after trauma. Lasers have been shown to have significant potential experimentally and clinically for welding and soldering of different types of tissues using various materials. Thermal damage without to tissue is a major hurdle to overcome in laser soldering. Laser soldering has been carried out using various types of solders. Since the thermal damage to the irradiated tissue is strongly dependent on the evaluated temperature achieved during the laser soldering process, hence the resultant surgical outcome is highly variable. In the dynamic mode, however, the laser probe was located perpendicularly to the incision and scanned the surface with a predefined speed until the soldering was finished set by upper temperature limit. Feedback control involves a set of sensors to measure some physical characteristic in tissue that is related to the degree of completion of the soldering process.
