Simulation of the effect of spot size on temperature field and weld forming in laser tissue welding
Cong Li,Kehong Wang,Jun Huang +2 more
TL;DR: In this article, a two-layer structure model of skin was developed and validated with the experimental results, which is based on the theory of bio-heat transfer, and the temperature response of the model, including the peak temperature, the temperature field distribution and the time behavior, were calculated according to the Gaussian distribution laser heat source.

Investigation on thermal damage model of skin tissue in vitro by infrared laser welding
TL;DR: In this paper, a model between laser processing parameters and thermal damage accumulation parameter of skin tissue in vitro was established based on full-factor experiments, where the laser power, spot moving speed, and pulse frequency were taken as independent variables, and the thermal damage parameter of the skin tissue was taken as dependent variables.

Effect of preloading force on capability of laser welding for skin tissue
TL;DR: In this paper , a Nd:YAG pulse laser was used to conduct welding experiments on the skin in vitro, and the results showed that the external preloading force has a significant effect on the strength of the tissue under laser welding.
