Multifunctional electrosurgical device

A multi-purpose electrosurgical device for treating biological tissues, comprising a first member comprising at a front end thereof a first electrode to form a first electrical contact with the biological tissues and a second member consisting of a single second electrode connected to a gripping element, the single second electrode forming a front end of the second member, to form a second electrical contact with the biological tissues, the first and second members being connected by an articulation pivot making it possible to bring the members closer to and further away from one another;

• the first electrode having a concave cross-section defining a concavity having an internal surface able to partly house the second electrode, the first electrode having external flanks defining an external surface complementary to the internal surface of the concavity, and, when the two members are brought together, in a pressure mode such that no tissue is gripped between the first electrode and the second electrode, an end of the second electrode is longer than an end of the first electrode to make the second electrode project from the first electrode, a longitudinal axis of the first electrode and a longitudinal axis of the second electrode are not parallel to one another, and the external surface of the first electrode that faces away from the second electrode and a projecting part of the second electrode are configured to deliver energy to the biological tissues therebetween.
