Embodiment Construction

[0023] With reference to the embodiment shown in the drawings, the reference numeral 10 designates as a whole an electrosurgical device for resecting a mass of tissue from the body of a human or animal patient, inter alia by means of plasma generation.

[0024] Apparatus 10 includes a generator system 12 configured to generate radio frequency electrical signals. The device 20 further comprises a handpiece 14 to be held by the operator and comprising an end 16 mounted with an active electrode 18 electrically connected to said generator system 12 .

[0025] Said signal generated by the generator system 12 is capable of polarizing the active electrode 18 so that when the active electrode 18 is in the immediate vicinity of the tissue mass M to be subjected to resection, the active electrode 18 is activated without propagating current through the patient's body B. A glow plasma discharge 19 is generated in the atmosphere between the tissue block.

[0026] In other words, device 10...

Abstract

The electrosurgical apparatus (10) comprises: a generator system (12) configured to generate a radio-frequency electric signal, and a handpiece (14) to be gripped by an operator and comprising an end (16) fitted with an active electrode (18) electrically connected to the generator system (12). The signal is capable of polarizing the active electrode (18) so as to generate a glow plasma discharge (19) in the atmosphere when the active electrode (18) is in the proximity of the tissue mass (M), without propagation of electric current through the patient's body (B).

Description

technical field [0001] The present invention relates to an electrosurgical device especially for resecting a mass of tissue from the body of a human or animal patient. Background technique [0002] It is widely known in the art to use electrosurgical devices comprising a generator system configured to generate radio frequency electrical signals and held by the operator and comprising active electrodes mounted with electrical connections to said generator system end of the handpiece. [0003] However, devices of the kind mentioned above suffer from some drawbacks. [0004] US 2006 / 293649 discloses a device designed according to the preambles of the appended independent claims, which requires a high polarization power, for example up to 300 W, in order to perform an ablation of the patient's body. Moreover, in addition to the active electrode, the device also requires another electrode (also known as a return plate), which is laid on the patient's body in order to attack the...
