摘要： 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.

摘要： The distal end of the surgical instrument has an electrically conducting front cylinder (10), with a distal point (12) and cylindrical first electrode (2). A tubular external conductor (20) is attached to the proximal end of the front cylinder, and has a cylindrical second electrode (4). An insulator element (50) is between the front cylinder and the external conductor. the electrodes are connected to an alternating current source. DETAILED DESCRTIPTION - The external conductor contains a rod-shaped inner conductor (40) between which and the external conductor is an insulating tube (30). A radial partition (52) between the front cylinder and external conductor leads onto the cylindrical enclosure wall (54) on the outer edge of the partition.

摘要： The system is coaxially arranged and the electrode set is of axial type with the electrodes in tandem and of liner configuration. The two electrodes are preferably insulated from each other by a dielectric, forming at the distal end and dipolar configuration with the dielectric of ceramics, polyimide etc. Typically the axially arranged linear electrodes are mutually axially displaceable, thus influencing the electric filed perpagation by selecting an appropriate electrode spacing. The core and jacket electrodes can form a fillering pin, when retract while forming an axial dipole, when extended for operation.

摘要： The invention relates to a surgical, grooved director (10) for collecting tissue in a minimally invasive manner, comprising an elongated hollow body composed of at least two segments (12, 16). At least one of said segments includes a cavity (18) for receiving tissue. The two segments can be dissociated from and moved relative to each other in such a manner that an opening between the segments is optionally released or closed. The director also comprises an electrically conductive ring or loop-shaped cutting element (24) which can be displaced relative to at least one of the segments and which is adapted to electrosurgically excise tissue that has entered the opening between the two segments of the hollow body.

摘要： The invention concerns an electrode arrangement for a surgical instrument for the electrothermal coagulation of human or animal tissue, comprising an elongate carrier, at least two electrodes which extend in the longitudinal direction of the carrier and which are connectable to an external ac voltage, and a plurality of self-supporting metal bar profile members which extend in the longitudinal direction of the carrier and which are connected together by means of one or more insulating spacer elements and form the electrodes. It is achieved in that at least one bar profile member is in the form of a hollow profile member or a solid profile member.
