| Research Abstract |
For the development of a substitutional supporting system for low-level-laser treatment (LLLT), the practical performance of an experimentally fabricated robot was evaluated and improved when needed. Three types of unit patterns "whirl", "circle" and "petal" were programmed and the robot gave eccentric rotary motions by drawing the unit patter to form a painted circle. It was confirmed that the robot could well manipulate the laser handpiece to irradiate the specified area of 4cm in diameter of the object 10cm apart from the laser tip at a rate of 3.5rev/sec. However, the movement became a little irregular due to the deficient mechanical stability of the light weighed robot against the resistance of the laser arm. It could be improved by making the robot fixed more stably. The "whirl" showed a little unfavorable motion and it was removed from the program. When the LLLT was performed on the hand on its back with CO_2 laser 1W for 10min, thermograph showed an increase in temperature by 1.7℃ in average in 5min irradiation. It showed no significant increase in temperature in the latter 5min irradiation, indicating the same tendency with the reference in which the temperature change was examined by the hand-manipulated LLLT for the disorder of temporomandibular joint. The pattern "circle" yielded a slightly concentrated increase in surface temperature of the object, while the pattern "petal" showed fairy uniform temperature changes. It was suggested from these findings that the robot with the unit pattern "petal" would be useful for substitutional manipulation of LLLT.
