A Novel Rotational Insertion Method for Deflection-free Delivery of a Microelectrode Into Deep Brain
Measuring deep brain neural activities with a microelectrode is of greatest importance in uncovering the mechanism of various brain disorders.In this operation, a microelectrode needs to be accurately inserted into deep the brain.However, a microelectrode of high flexibility would bend at encountering a layer of tough tissue during insertion, which would lead to deflection and impaired targeting accuracy.To deal with this problem, a rotational insertion method has been developed in this paper for deflection-free insertion.Rotation helps generate a dynamic anti-bending force to prevent buckling, and this force becomes larger with the increase of rotational speed.Thus, by controlling the rotational speed at which insertion is carded out, deflection-free insertion of a microelectrode deep into brain can be realized.The effectiveness of this method has been experimentally confirmed.
