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 first 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 medical instrument so that it can manipulate tissue. The advantage of the present invention, in contrast to mechanical tools, is that tissue can be manipulated with a single tip of a conducting element, without folding and piercing of the tissue, thus avoiding damage to the tissue.

L'invention concerne un manipulateur de tissus électro-adhésif capable de manipuler des tissus au moyen d'un seul élément conducteur. Le manipulateur comprend un élément conducteur, des moyens électriques et des moyens de commande capables de produire une première et une seconde impulsion à la demande. La première impulsion produit un état adhésif entre l'élément conducteur et la couche de tissus assez résistant pour manipuler la couche de tissus. La seconde impulsion, qui présente une énergie d'impulsion plus élevée que la première impulsion, produit un second état non adhésif, permettant de détacher la couche de tissus adhérée de l'élément conducteur. Le dispositif électro-adhésif peut être combiné à un instrument médical pour améliorer les possibilités de l'instrument médical, de manière à ce qu'il puisse manipuler les tissus. De manière avantageuse, par rapport aux outils mécaniques, les tissus peuvent être manipulés par une seule pointe de l'élément conducteur, sans plier et couper le tissu, ce qui permet d'éviter les dommages provoqués sur les tissus.
