Abstract
An electrosurgical device can have a housing and an electrode defining an energizable surface at least partially positioned externally of the housing. The electrode can move longitudinally relative to the housing. A shank of the electrode can be positioned within the housing and configured to urge against an energizable element in the housing. The energizable element can have a longitudinally movable electrical coupler configured to electrically couple with the shank portion when the shank portion urges against the energizable element. Related methods are also disclosed.
Claims20
An electrosurgical device comprising:
- a housing and an electrode defining an energizable surface at least partially positioned externally of the housing and a portion positioned at least partially within the housing;
- a shank portion positioned internally of the housing in a sliding engagement with the electrode, wherein the energizable surface and the shank portion are electrically coupled with each other;
- an energizable element positioned in the housing, wherein the electrode and the shank are longitudinally movable relative to the housing and the energizable element in correspondence with each other until the shank urges against the energizable element, wherein the electrode is movable relative to the housing, the energizable element and the shank when the shank urges against the energizable element.
An electrosurgical device comprising:
- a housing;
- a power element immovable relative to the housing;
- an electrode and a shank slidably engaged with each other and defining an electrode and shank assembly, wherein the electrode and shank assembly is movable within and relative to the housing from an at-rest position spaced apart from the power element to an in-use arrangement in which the shank urges against the immovable power element.
An electrosurgical device comprising:
- a housing and an electrode defining an energizable surface at least partially positioned externally of the housing and a shank portion positioned internally of the housing, wherein the energizable surface and the shank portion are electrically coupled with each other;
- an energizable element positioned in the housing and having a first electrical coupler being immovable relative to the housing and a second electrical coupler being movable relative to the housing, wherein the first electrical coupler and the second electrical coupler are electrically coupled to each other, wherein the electrode is movable relative to the housing such that the shank portion is configured to urge against and electrically couple to the second electrical coupler in correspondence with a force applied to the energizable surface of the electrode.
An electrosurgical device, comprising:
- a housing and an electrode defining an energizable surface at least partially positioned externally of the housing and a shank portion positioned internally of the housing, wherein the energizable surface and the shank portion are electrically coupled with each other;
- an energizable element positioned in the housing and having a first electrical coupler being immovable relative to the housing and a second electrical coupler being movable relative to the housing, wherein the first electrical coupler and the second electrical coupler are electrically coupled to each other, wherein the electrode is movable relative to the housing such that the shank portion is configured to urge against and electrically couple to the second electrical coupler in correspondence with a force applied to the energizable surface of the electrode;
- a first resiliently compressible spring element configured to urge the first electrical coupler and the second electrical coupler apart, and to electrically couple the first electrical coupler to the second electrical coupler;
- a stop member configured to limit an extent of distal movement of the second electrical coupler;
- and
- a second resiliently compressible spring element configured to urge the electrode distally of the energizable element so as to define a gap between the shank portion of the electrode and the second electrical coupler sufficient to decouple the shank portion of the electrode from the second electrical coupler.
