Patent number: 11207121Abstract: A device (10) for tissue coagulation, in particular for fusion, encompasses an electric source (18), which is connected or which can be connected to electrodes (12, 13) for influencing biological tissue (11) with current. A control unit (22) controls the source (18) during phases I and II of the tissue fusion. These phases I and II correspond to operating phases I, II and III of the device (10). During operating phase I, a monitoring unit (23) determines the energy E1, which is applied into the tissue (11). In the subsequent operating phases II and III, the control unit (22) controls the source (18) by means of the determined energy E1. Such a device turns out to be particularly reliable and to be robust in use.Type: GrantFiled: May 4, 2018Date of Patent: December 28, 2021Assignee: Erbe Elektromedizin GmbHInventors: Heiko Schall, Daniel Schaeller

Patent number: 11197711Abstract: A tissue fusion instrument having electrodes that are only connected in a punctiform manner to their electrode carrier such that they are electrically conducting and thus, heat-conducting. As a result, heat transfer from the electrode to the respective electrode carrier is restricted. This, on one hand, benefits the desired surgical outcome and, on the other hand, prevents parasitic heating of the surgical instrument and concomitant damage to surrounding tissue.Type: GrantFiled: April 9, 2019Date of Patent: December 14, 2021Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Klaus Fischer, Achim Brodbeck, Daniel Schaeller

Patent number: 10314643Abstract: A surgical instrument 10 suitable for sealing tissue includes a tool 15 with at least one branch 16 comprising an electrode unit 35, which consists of a sheet metal part 35. The part 35 is anchored in a positive manner in a plastic body 34. Strip sections 40, 41 of the metal part 35 extend into the plastic body 34, encompassing openings 42, 42 or slits 43, 43a, through which the plastic body 34 extends. A positive anchoring of the sheet metal part 35 in the plastic body 34 and minimizing of the heat introduction into the plastic body 34 is thus attained. The thermal capacity of the sheet metal part 35 and the thermal conductivity of the plastic body 34 are low, so that consistently positive coagulation results are reached even after repeated use in short succession, regardless of the initial temperature of the tissue contact surfaces 36.Type: GrantFiled: September 10, 2014Date of Patent: June 11, 2019Assignee: Erbe Elektromedizin GmbHInventors: Marcus Amann, Daniel Schaeller, Volker Mayer, Martina Düppuis

Patent number: 9510889Abstract: An apparatus for coagulating tissue, including a gas-delivering device for delivering a plasma comprised of an ionized inert gas from the outlet of the gas-delivering device, an electrode adapted to supply a high-frequency current that projects out of the gas-delivering device and a guiding device disposed at a distal end of the electrode. The relative configuration of the outlet of the gas-delivering device and the guiding device are such that the plasma (and an electric arc) can be directed in any direction 360° with respect to the outlet of the gas-delivering device. The plasma is directed along a path of least electric resistance, thus causing the plasma to be directed to a tissue to be treated, regardless of a position of the tissue relative to a rotational position of the outlet of the gas-delivering device.Type: GrantFiled: June 13, 2014Date of Patent: December 6, 2016Assignee: Erbe Elektromedizin GmbHInventors: Uwe Schnitzler, Daniel Schaeller

Patent number: 8979845Abstract: Electrosurgical forceps for efficiently severing of hollow organs, in particular vessels. The electrosurgical forceps have a first branch and a second branch for gripping the hollow organ. The forceps have at least one neutral electrode on the second branch, at least one first coagulation electrode and a second coagulation electrode that is disposed on the first branch for applying a first HF current by means of the coagulation electrode, and at least one cutting device, which is arranged between the coagulation electrodes in order to sever the hollow organ in a cutting region. The cutting device has a cutting electrode for applying a second HF current between the cutting and neutral electrodes.

Patent number: 8308718Abstract: A cryosurgical instrument and a method for separating a tissue sample from surrounding tissue of a biological tissue that is to be treated. The cryosurgical instrument includes a probe for guiding a probe head on to a biological tissue to be treated, and gas conduits for delivering coolant gas. The probe head is designed so that, in order to collect a tissue sample, a limited region of the tissue is cooled by means of the gas delivered and is separated from the surrounding tissue in a state in which it is frozen on the probe head. The instrument includes a support tube or hose in which the probe is guided and which can be moved relative to the probe in such a way that the surrounding tissue can be counter-supported during separation of the tissue sample.Type: GrantFiled: December 11, 2007Date of Patent: November 13, 2012Assignee: Erbe Elektrommedizin GmbHInventors: Klaus Fischer, Matthias Voigtländer, Daniel Schäller, Mara Szyrach, Irina Sigle
