Abstract
Official abstract text for this publication.
An electrosurgical instrument is provided for the treatment of tissue, the instrument comprising an instrument shaft ( 10 ) having a longitudinal axis, and an electrode assembly at one end of the shaft. The electrode assembly comprises a first tissue treatment electrode ( 11 ), a second tissue treatment electrode ( 14 ), and a third electrode ( 25 ) which is electrically insulated from the first and second tissue treatment electrodes by means of an insulation member ( 12 ). The first and second tissue treatment electrodes ( 11, 14 ) each have an exposed surface for treating tissue, the exposed surface of the first tissue treatment electrode ( 11 ) being such as to treat tissue disposed on the longitudinal axis, and the exposed surface of the second tissue treatment electrode ( 14 ) being such as to treat tissue disposed laterally of the longitudinal axis. The instrument has a first set of connections ( 62 A, 62 B) by which the first tissue treatment electrode ( 11 ) can be placed in circuit with the second electrode ( 14 ) such that, in use, a current path is established therebetween. The instrument has a second set of connections ( 62 B, 62 C) by which the second tissue treatment electrode ( 14 ) can be placed in circuit with the third electrode ( 25 ) such that, in use, a current path is established therebetween.
