Patent number: 10537376Abstract: A high-frequency surgical device having a high-frequency generator, which produces a high-frequency output signal for treating, in particular for cutting or coagulating, biological tissue, the high-frequency generator being designed in such a way that the output signal of the high-frequency generator has a predetermined fundamental frequency and a modulation apparatus being provided, which is used to modulate the output signal with a modulation frequency, the modulation frequency being smaller than the fundamental frequency. The high-frequency surgical device is characterized in that the modulation frequency is at least 100 kHz, and in that the output signal can be modulated in such a way that a crest factor of the modulated output signal suitable for a specific application of the high-frequency surgical device arises.Type: GrantFiled: May 23, 2013Date of Patent: January 21, 2020Assignee: ERBE ELEKTROMEDIZIN GMBHInventor: Martin Hagg

Patent number: 10524860Abstract: In surgery using monopolar HF, there is a constant risk of patients suffering burns at the neutral electrode. Said problem stems from the fact that numerous methods have been devised by which relatively high HF currents are applied for extended periods of time. The present invention solves said problem by providing a neutral electrode, device that is to be used for applying an HF current to a biological tissue. Said improved neutral electrode device comprises at least one latent heat accumulator for absorbing heat. Thus heat peaks can be at least temporarily accumulated until the accumulated thermal energy can be safely released.Type: GrantFiled: June 20, 2014Date of Patent: January 7, 2020Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Martin Hagg, Peter Selig

Patent number: 9949782Abstract: The method disclosed herein permits the operator of an electrosurgical device to move a safety switch-off threshold for a contact resistance at a neutral electrode from a first value to a second and slightly higher value. This way, for patients with a relatively high resistance yielding a somewhat elevated contact resistance despite correct attachment of the neutral electrode, uninterrupted operation of the device is achievable.Type: GrantFiled: June 13, 2012Date of Patent: April 24, 2018Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Martin Hagg, Juergen Beller, Peter Selig

Patent number: 9044545Abstract: A fluid applicator is fed by a fluid delivery arrangement containing an energy storage such as a pressure vessel. The gas pressure acts on a container that has been prefilled with the ejection fluid. The fluid to be ejected is thus subject to constant pressure. With a valve, the user can initiate the ejection of the desired amount of fluid with constant intensity. The check valve may also be a regulating valve which can be used by the user to vary the intensity of the effect. The user need only release the system, e.g., by puncturing the pressure vessel, to then be able to directly inject the fluid in a defined or metered manner via the probe, i.e., the fluid applicator. It is also possible to configure the entire injection device as a single-use system and to prefill the fluid applicator up to its fluid exit opening.Type: GrantFiled: November 13, 2013Date of Patent: June 2, 2015Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Martin Hagg, Ralf Kühner

Patent number: 8747298Abstract: A probe manipulator which has a grip device that can be held by a user in order to facilitate manipulation of a probe when the latter has been inserted into a channel of an endoscope. Connection devices are provided for releasably connecting the grip device to the probe in such a way that the probe may be rotated or displaced by rotation or displacement of the grip device. The connection device is connectable such that the probe need not be fed through the grip device, but that the grip device may be placed at any point along the length of the probe.Type: GrantFiled: February 13, 2007Date of Patent: June 10, 2014Assignee: Erbe Elektromedizin GmbHInventors: Uwe Schnitzler, Martin Hagg

Patent number: 8679143Abstract: An appliance for water-jet surgery is provided that includes a plurality of supply cylinder and piston arrangements in each of which is stored a working fluid that can be expelled, by means of the piston, through an outlet into a pressure conduit. At least one actuation device is provided to actuate the piston of each supply cylinder. By means of a change-over device to change the actuation from the piston of one supply cylinder to the piston of another supply cylinder, it is ensured that the working fluid can be expelled into the pressure conduit from consecutively emptying supply cylinders.
