Publication number: 20190167075Abstract: The device comprises an endoscope shaft through which extends a working channel ending at an outlet side of the shaft. A guiding element extends through the working channel, said guiding element being preferably guided in longitudinal direction in and along the working channel. The device is set up in such a manner that the distal end section of an instrument extending in longitudinal direction next to the shaft can be moved alongside the shaft beyond the outlet side in order to move the working section of the instrument away from the outlet side so as to lengthen the distal end section of the device. The instrument is coupled to the guiding element in order to guide the working section of the instrument in a transverse direction away from the outlet side in a region opposite the outlet side in order to work in the region with the instrument.Type: ApplicationFiled: December 5, 2018Publication date: June 6, 2019Inventors: Klaus Fischer, Thomas Staebler, Charlotte Herrberg, Achim Brodbeck

Publication number: 20190038333Abstract: A cryosurgical instrument includes a feed line for conveying fluid into an expansion chamber. The feed line has a capillary line section that terminates in the expansion chamber and forms an aperture for the fluid to undergo the Joule-Thomson effect. The flow cross-section of the feed line decreases in at least one transition section of the feed line in the form of a funnel. Following each transition section there preferably follows a step section, in which latter section the flow cross-section is preferably largely constant. The last step section is preferably formed by the capillary line section. Due to the acceleration of the fluid in the transition sections and the abating of pressure fluctuations in the capillary tube section and, optionally in the additional step sections, the expansion range in the expansion chamber is increased, without impeding the backflow of the expanded gas out of the expansion chamber.Type: ApplicationFiled: August 1, 2018Publication date: February 7, 2019Inventors: Achim Brodbeck, Joerg Kronenthaler, Marcus Adler, Hanna Andel, Klaus Fischer

Publication number: 20180353233Abstract: An instrument for electrosurgical treatment including an instrument head which forms a conveying body with a gas-fillable lumen. The lumen is connected to at least one first opening and at least one second opening in the instrument head. A primary stream of gas leaves through the first opening. The second opening is arranged such that a secondary stream exits the second opening next to the primary stream and/or with additional secondary streams out of additional second openings—away from the instrument head, at least partially peripherally surrounding the primary stream. An electrode is located in the flow of gas exiting out of the first opening for igniting a plasma between the first opening and the tissue to be treated. Due to the secondary stream accompanying the primary stream, an ignition of the plasma is successful even if the instrument is at a relatively large distance from the tissue.Type: ApplicationFiled: June 6, 2018Publication date: December 13, 2018Inventors: Achim Brodbeck, Charlotte Herrberg, Thomas Staebler

Patent number: 10130414Abstract: A sealing instrument (10) including two branches (15, 16) with sealing jaws (19, 20, 36, 37) acted on by a sealing voltage preferably between 80 and 120 volts. Tissue receptacles (53, 54) are separated from one another by a wall-like extension (24), which at its lower edge carries a cutting electrode (31), are defined between the branches (15, 16). A cutting voltage from 300 to 500 volts is applied between a branch (16) and the cutting electrode. When the branches are closed the grasped tissue is sealed simultaneously between the sealing jaws (19, 36 and 20, 37) and is severed by the cutting electrode (31). Even though the tissue is severed completely; for example after 0.3 to 0.5 seconds and the sealing requires more time, the rolls of tissue grasped in the tissue receptacles (53, 54) act as form-fitting protection of the vessel edges in the tool (12).Type: GrantFiled: June 24, 2015Date of Patent: November 20, 2018Assignee: Erbe Elektromedizin GmbHInventors: Rolf Weiler, Volker Mayer, Heiko Schall, Achim Brodbeck, Tobias Amann

Publication number: 20180140342Abstract: The inventive method of manufacturing a cryoprobe uses an assembly pin (25) for receiving a sleeve (20) that is to form a part of the head (13) of the cryoprobe and comprises three abutment surfaces (27, 29, 30) that are axially offset relative to each other, said abutment surfaces ensuring, following the attachment of the sleeve (20) and the nozzle (24) to the tube end (19), the correct axial positioning of the nozzle (24) and the sleeve (20), in particular, relative to the distal end surface (18) of the tube end (19). Consequently, the position of the nozzle (24) in the expansion chamber (23) that formed after the sleeve (20) was closed and thus the function of the cryoprobe are ensured.Type: ApplicationFiled: November 17, 2017Publication date: May 24, 2018Inventors: Klaus Fischer, Jörg Kronenthaler, Achim Brodbeck, Marcus Adler

Publication number: 20160066980Abstract: An instrument (10) provided for simultaneous coagulation and dissection of tissue has tissue receptacles between the cutting electrode and the sealing electrode for the formation of tissue bulges to secure the tissue in the tool during the sealing process. In order to make it possible to form voluminous tissue bulges and to prevent their atrophy, the cutting electrode is supplied by a current limiting component, preferably in the form of a coupling capacitor. Thereby, in particular, in tissue that can be cut through easily, but which requires a long time for sealing, a high degree of process safety is achieved.Type: ApplicationFiled: September 3, 2015Publication date: March 10, 2016Inventors: Heiko Schall, Achim Brodbeck, Rolf Weiler, Volker Mayer, Tobias Amann

Patent number: 8968303Abstract: In a method suitable for tissue fusion or coagulation, after the start of treatment of the tissue, i.e., after completion of a first phase, a second phase is commenced, during which the biological tissue is treated for a certain specified process time with moderate energy input. The specification of a negative internal resistance of a supplying source enables the process in the second phase to have a treatment time that remains constant and thus avoids premature drying-out of the tissue. A sufficient and reliable bonding of the participating proteins in the moist milieu is reached.Type: GrantFiled: April 30, 2012Date of Patent: March 3, 2015Assignee: Erbe Elektromedizin GmbHInventors: Heiko Schall, Achim Brodbeck, Martin Fritz
