ELECTRO-ADHESIVE TISSUE MANIPULATOR

摘要

An electro-adhesive tissue manipulator capable of manipulating tissue with a single conducting element is provided. The manipulator includes a conducting element, an electrical means and a control means capable of generating a fir st and a second pulse on demand. The first pulse generates an adhesive state between the conducting element and the tissue layer strong enough to manipulate the tissue layer. The second pulse, which has higher pulse energy than the first pulse, generates a non-adhesive state to detach the adhered tissue layer from the conducting element. The electro-adhesive device could be combined with a medical instrument to enhance the capabilities of the medica l instrument so that it can manipulate tissue. The advantage of the present invention, in contrast to mechanical tools, is that tissue can be manipulate d with a single tip of a conducting element, without folding and piercing of t he tissue, thus avoiding damage to the tissue.
