Özet (Çeviri)
Intra Cytoplasmic Sperm Injection is one of the conventional methods in infertility treatment. In this method, a single sperm is injected into an oocyte with a directinjection under a microscope. However; there are several reasons which reduce the effects of the method significantly such as low success rates, long training, low efficiency, and contamination. Basically, this technique suffers from low efficiency and success rate. In the proposed system, stepper, delryne and servo motor have been employed on a platform and a glass holding micropipette was connected to the system. The design of the servo and stepper motors and the design of the micropipette cause vibration in the proposed system. Therefore, Vibrational analysis is essential in designing micromanipulators. These analyses will be considered for precision recognition. To analyze the total frequency of the proposed system, the micromanipulation system was divided into two main parts based on different type of frequencies occurred on the system. This work focuses on the lateral vibration of micropipette. Natural and resonance frequency of micropipette were calculated and validated. The effects of stepper and servo motor on micropipette displacement are also investigated and discusses in this report. In this paper, maximum deflection was obtained 700 Nanometer at the end of the micropipette, which is totally negligible in compare to the size of the cell. Furthermore, displacement of the micropipette caused by servo and stepper was initially 2um and after 35 seconds reached to constant equilibrium. Index terms- micro-manipulation, Euler-Bernoulli, vibration analyses
