Patent ID: 7335223

Claim:
An apparatus for the treatment of body tissue comprising a treatment instrument for the treatment of the body tissue to be treated, the treatment instrument being adapted to deliver treatment energy in pulse form; a measuring unit for measuring the actual value of a parameter of the body tissue at at least one measuring point of the body tissue; an identifier connected to the measuring unit for identifying the body tissue to be treated on the basis of the actual value and for outputting a co-ordinate signal containing the co-ordinates of the body tissue to be treated; a positioning device connected to the identifier for receiving the co-ordinate signal for moving to the body tissue to be treated with the treatment instrument on the basis of the co-ordinate signal; an activator for activating the treatment instrument; a matching device for matching the co-ordinate system of the body tissue to be treated and the co-ordinate system of the treatment instrument; and an updating device which is connected to the measuring unit, to the identifier and to the matching device, the updating device including at least one counter for counting the pulses delivered by the treatment instrument and being adapted to output an updating signal after a first given number of delivered pulses (N) to the measuring unit for triggering renewed measurement of the actual value and to the identifier for renewed identification of body tissue to be treated based on the renewed measurement, the identifier outputting a renewed coordinate signal to the positioning device for effecting treatment and the updating device further adapted for the repeated delivery of a matching signal after a second given number of delivered pulses (M) to the matching device for re-triggering co-ordinate system matching of co-ordinate system of the body tissue to the co-ordinate system of the treatment instrument to reduce displacement of the two co-ordinate systems to each other.
