A polypectomy snare comprising two snare parts has a snare part that is completely electrically insulated and another snare part that is not electrically insulated in at least one distal portion thereof. The snare furthermore has at least one electrically insulated, HF surgically inactive skid at its distal end.

RF surgical resection snare for flexible endoscopy

Symmetrical and asymmetrical snares are used for endoscopically controlled methods by which tumors in hollow organs of the gastrointestinal tract can be ensnared and RF-surgically removed from the organ wall for diagnostic and/or therapeutic purposes. These snares are characterized in that one of the two snare portions, in the case of asymmetrical snares the longer of the two snare portions, is completely electrically insulated or is made from electrically non-conductive material and that the other of the two snare portions is made from electrically conductive material and its surface is not electrically insulated. In one embodiment, the asymmetrical snare is characterized in that the long snare portion is so much flexurally stiffer than the short snare portion that it tensions the short snare portion like the string of a bow.

Monopolar RF-surgical snares

An apparatus for argon-plasma coagulation (APC) is disclosed, in which after activation of the apparatus for APC a specified amount of noble gas flows out of the APC instrument before the high-frequency voltage for ionizing the noble gas is switched on, or can be switched on. As a result an increase in safety is achieved.

Method and apparatus for plasma surgery

Electrosurgical instrument for the coagulation of biological tissue, wherein from a gas source a noble gas is sent through a tubular probe to at least one outflow opening in a distal end region of the probe, with an electrode device disposed in the distal end region of the probe, which can be connected to an HF source in order to supply a coagulation current, and wherein the at least one outflow opening has a slit-like structure, such that at least two outflow openings are provided, disposed opposite one another with their long axes oriented perpendicular to or at an angle to, but not parallel to a long axis of the probe, and that the probe is flexibly constructed at least in the region of the outflow openings, in such a way that when the probe is bent in the region of the outflow openings, their cross sections are enlarged or reduced.
