The Research on Constructure Principle of Micromaniputation System Used in Clone Technique
Abstract：This paper introduces the constructure principle of a kind of micromanipulation system,which can be used in the clone technique.Clone technique is the most promising technique in the modern biology field.The traditional microinjector have some shortcomings,such as rare capture method.Plane image is not enough for aiming at target effectively.This micromanipulation system in this paper uses.microclamp to capture the object,which senses the clamping force and the hardness of the object surface.It also uses the stereo image in aiming at target more directly and more precisively.This paper also tells the history of the concern technique in biological field and the relationship between the work pieces and units techniques of the micromanipulation system in detail.At the end,we point out the possibility of the realization of this micromanipulation system.Keywords：Clone;Micromanipulation system;Construction- 51
