Abstract
A hollow surgical probe for the minimally invasive removal of tissue has an elongate hollow body and an electrical conductive ring-shaped or loop-shaped cutting element. The elongate hollow body includes two segments of which at least one encloses a cavity for receiving tissue and which can be separated from each other and which are movably relative to each other in such a way that an opening between the segments is to be selectively opened or closed. The electrically conductive ring-shaped or loop-shaped cutting element is movable relative to at least one of the segments and is adapted for electrosurgically cutting out tissue which has penetrated into the opening between the hollow body segments.
Claims36
A surgical probe for the minimally invasive removal of tissue, comprising:
- an elongate hollow body comprising a first segment and a second segment, at least the first segment includes an open cavity for receiving tissue and the second segment engages the open cavity of the first segment to enclose a hollow space, the first and second segments being movable relative to each other to selectively open or close access to the hollow space;
- and
- an electrically conductive ring-shaped or loop-shaped wire cutting element, separate from the first and second segment, which is movable relative to at least one of the segments and which is adapted for electrosurgically cutting out tissue which has penetrated into an opening between the hollow body segments when the segments are in an open configuration.
A surgical probe for the minimally invasive removal of tissue, comprising:
- an elongate hollow body comprising a first segment and a second segment, at least the first segment includes an open cavity for receiving tissue and the second segment engages the open cavity of the first segment to enclose a hollow space, the first and second segments being movable relative to each other to selectively open or close access to the hollow space;
- an electrically conductive ring-shaved or loop-shaped cutting element which is movable relative to at least one of the segments and which is adapted for electrosurgically cutting out tissue which has penetrated into an opening between the hollow body segments when the segments are in an open configuration;
- and
- an ejector for ejecting tissue from the hollow probe, wherein
- the ejector is arranged axially displaceably within the cavity.
A surgical probe for the minimally invasive removal of tissue, comprising:
- an elongate hollow body comprising a first segment and a second segment, at least the first segment includes an open cavity for receiving tissue and the second segment engages the open cavity of the first segment to enclose a hollow space, the first and second segments being movable relative to each other to selectively open or close access to the hollow space;
- a thrust rod guided in one of the two segments connects the two segments an electrically conductive cutting element comprising a ring-shaped or loop-shaped portion and a cutting arm portion connecting the loop portion to the thrust rod in an electrically conductive manner, wherein the cutting element is movable relative to at least one of the segments and which is adapted for electrosurgically cutting out tissue which has penetrated into an opening between the hollow body segments when the segments are in an open configuration.
