Patent number: 11696794Abstract: A device for controlling the energy supply to a medical instrument contains the medical instrument and an energy supply device. The energy supply device has at least a first and a second energy supply mode that can be preselected on the energy supply device and which supplies energy to the medical instrument according to a preselected energy supply mode. The energy supply device additionally has a third mode which differs from the at least two energy supply modes, can be preselected on the energy supply device, can detect an actuation of an energy supply operating element arranged on the medical instrument, and can carry out the supply of energy to the medical instrument in the first or second mode based on the detected actuation.Type: GrantFiled: July 31, 2017Date of Patent: July 11, 2023Assignee: Aesculap AGInventors: Erik Walberg, Stefan Eick, Anton Keller

Patent number: 11547461Abstract: A method and device for controlling a treatment procedure includes a treatment tool, an energy source, and a controller. The controller controls the energy source such that in a first treatment phase, power fed into the material to be treated is controlled with an increasing course. An impedance detector determines the impedance course and/or the present impedance of the material to be treated, and recognizes the achievement of an impedance minimum. A timer is started upon recognition of an impedance minimum, and upon recognition of a further impedance minimum within the specific time interval, the timer is reset. If no new impedance minimum is detected within the specific time interval and the time interval expires, the controller switches the power control to constant power or to a power course with an altered gradient. Upon fulfilling a specific criterion, there is a switchover from power control to voltage control.Type: GrantFiled: October 23, 2015Date of Patent: January 10, 2023Assignee: Aesculap AGInventors: Anton Keller, Stefan Eick, Thomas Maser

Patent number: 11246652Abstract: Surgical tissue fusion instrument and support structure having two gripping structures which are movable relative to each other and which are designed to bring together biological tissue sections that are to be connected to each other, with heat-generating means which are assigned to the gripping structures and, during tissue fusion, cause heat to be introduced in the area of a connection site of the biological tissue sections, and also with a support structure which is held between the gripping structures and, during tissue fusion, is operatively connected to the tissue sections. The support structure has at least one additional physical functional structure for aiding or promoting the tissue fusion.Type: GrantFiled: March 18, 2016Date of Patent: February 15, 2022Assignee: AESCULAP AGInventors: Rainer Bargon, Bernd Blender, Stefan Eick, Nikolaus Hafner, Patrick Heizmann, Eugen Herner, Christian Huber, Christof Merckle, Erich Odermatt, Christoph Rothweiler

Patent number: 10779844Abstract: Surgical tissue fusion instrument having two gripping structures which are movable relative to each other, are designed for gripping and bringing together biological tissue sections, and are assigned heat-generating means designed in such a way that tissue fusion takes place between the biological tissue sections by heat being supplied in the area of the gripping structures. At least one gripping structure is assigned a fluid-conducting system, which is designed to supply at least one liquid or flowable additive to the tissue sections during a tissue fusion process.Type: GrantFiled: March 18, 2016Date of Patent: September 22, 2020Assignee: AESCULAP AGInventors: Rainer Bargon, Bernd Blender, Stefan Eick, Nikolaus Hafner, Patrick Heizmann, Eugen Herner, Christian Huber, Christof Merckle, Erich Odermatt, Christoph Rothweiler

Patent number: 10687885Abstract: A method of controlling an electrosurgical HF apparatus, as well as an HF apparatus, includes an electrosurgical instrument and an HF generator for generating an HF current. The HF generator is in a locked state in which its activation is not possible. An application to be carried out is to be selected prior to a user-side activation of the HF generator, whereby the HF generator is unlocked.Type: GrantFiled: September 10, 2014Date of Patent: June 23, 2020Assignee: AESCULAP AGInventors: Thomas Maser, Heiko Reichle, Anton Keller, Stefan Eick

Patent number: 9603655Abstract: An electrosurgical instrument includes a proximal end and a distal end having a jaw member assembly at the distal end including a first jaw member and a second jaw member movable relative thereto. The jaw members can be transferred relative to each other from an opening position into a gripping position in which they are arranged to be closer to each other than in the opening position. Each jaw member has at least one electrode connectable to an electric power source and electrodes of both jaw members being adapted to interact for sealing body tissue held between the jaw members in the gripping position, actuating means for transferring the jaw members from the opening position into the gripping position and means for limiting the closing width of the jaw members, when they are transferred from the opening position into the gripping position.Type: GrantFiled: September 14, 2012Date of Patent: March 28, 2017Assignee: Aesculap AGInventors: Theodor Lutze, Anton Keller, Dieter Weisshaupt, Stefan Eick, Christoph Rothweiler, Eugen Herner
