US 12,727,936 B2 · Electrode unit, treatment system and method for operating electrode unit

Abstract

An electrode unit of the invention includes: an electrode including one end and another end, the other end including a free end; and an electrode supporting portion that supports the one end of the electrode. The electrode is disposed in a second plane that is different from a first plane in which the electrode supporting portion is moved to advance or withdraw when the electrode supporting portion is moved to advance or withdraw in a direction along a longitudinal axis of the electrode supporting portion, and the electrode is supported by the electrode supporting portion via a flexed portion projecting from the first plane to the second plane.

Dependent claims

An electrode unit comprising:

a cantilevered electrode including a first end and an unsupported second end;
an electrode support that supports the first end of the electrode, the electrode support extending along a longitudinal axis direction;
and
an arm disposed at a position at which the arm faces the electrode support, such that the electrode is interposed between the arm and the electrode support, the arm being configured to retain a surface of a tissue;
wherein an entirety of the electrode extends in a direction offset from the longitudinal axis direction;
the electrode directly extends from a side surface of the electrode support;
and
the electrode extends from the electrode support towards the arm.
