  • Patent number: 10675048
    Abstract: In the case of an electrosurgical instrument, provision is made for a tool (16), for the operation of which at least one, preferably two pull/thrust elements (39, 40) and a sliding element (56) are required. The sliding element (56) is held between a pull/thrust element (39) and a thrust bearing, wherein the thrust bearing can be formed by means of a further pull/thrust element (40). This arrangement utilizes the fact that the sliding element must only be activated, when the pull/thrust element is tensioned tightly. This concept of guiding the sliding element at the pull/thrust element provides for the simple design of instruments comprising long shafts, wherein separate measures for laterally reinforcing the sliding elements do not need to be taken.

  • Patent number: 10624689
    Abstract: The ablation device (11) according to the invention is distinguished by a head (20) having a noncircular cross-section and by electrodes (32, 33) being positioned at an acute angle relative to each other. Due to the angular arrangement of the electrodes and the appropriate configuration of the channels (28, 29), there results an approximately fan-shaped plasma beam with which—in particular with the alternating activation of the two electrodes—a wide strip-shaped ablation region can be achieved on hollow organs of living beings. Handling is reliable and simplified, and, compared to existing measures, the treatment time is reduced.

  • Patent number: 10617464
    Abstract: In the case of an instrument (10) for coagulation and fusion as well as for severing vessels, provision is made for two shanks (19, 20), between which a vessel is to be gripped and fused. A blade (21) for severing the coagulated and fused vessel is provided with an isolator (40), which isolates the blade (21) against at least one of the electrodes or shanks (19, 20), respectively. On the other hand, the blade (21) is preferably in mechanical contact with at least one of the electrodes or shanks (19, 20), respectively, so that a safe separation of the fused biological tissue or vessel, respectively, is attained. This concept can be used to increase the safety of surgery and to miniaturize the tool (18) towards smaller sizes.

  • Patent number: 10603095
    Abstract: A method for the selective elevation and separation of tissues comprised of multiple layers and a surgical instrument for performing the method. The method may be performed without the requirement of a solid mechanical device insertion or transection through the mucosal layer. In particular, the method and surgical instrument may be used for the selected separation and/or resection of selected portions of benign or malignant tissues (e.g. defining tissue planes, polyp elevation and removal, submucosal tissue tunnelling, endoscopic mucosa resection, etc).

  • Patent number: 10575891
    Abstract: The ablation system (10) according to the invention works with an ablation probe (12, 12a) that comprises two alternatingly working spark plasma electrodes (31, 32). They generate a plasma beam (47, 48) having a non-circular cross-section, which beam is to be guided—transversely with respect to the large longitudinal axis of its preferably oval cross-section—over the tissue to be ablated, in particular the mucosa (14). In doing so, it is possible to treat large-area tissue regions by means of a reliable and easily controllable procedure.

  • Patent number: 10524860
    Abstract: 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.

  • Patent number: 10512502
    Abstract: The invention relates to tissue scissors (10) with improved stability and improved handling that have two structurally and electrically different branches (11, 12). While the sliding surface (25) of the first branch (11) has a metal-ceramic hard material layer (30), such as, for example, titanium nitride, the second sliding surface (34) of the second branch (12) has an electrically non-conductive ceramic layer (33). The material mating produces great mechanical resistance to abrasion in the bearing (17) and on the cutting edges (28, 35). At least one of the branches, in particular branch (12), can have a cermet body (36) to improve the cooling of the cutting edge (35 (28)) and/or keep it sharp, to prevent heating of the branches (11, 12) during coagulation and sticking of the tissue.

  • Patent number: 10485602
    Abstract: A cryosurgical apparatus with a temperature regulator. For better therapeutic success, it is desirable to set the temperature applied to a cryosurgical instrument as exactly as possible. Conventional apparatuses have corresponding temperature sensors allowing the regulation of the cooling power in the cryosurgical instrument such that the cooling power corresponds to a predefined value. However, the dimensions of some temperature sensors prevent them from being provided within a cryoprobe. Furthermore, suitable temperature sensors are expensive and have low durability. This problem is solved by the disclosed temperature regulator for regulating the temperature of a cryoprobe, which supplies an at least partly liquid refrigerant at a first pressure to an evaporation region such that the coolant evaporates at least temporarily under the presence of a second pressure for cooling a cooling portion of the cryoprobe. A pressure setting means that sets at least the second pressure is also provided.

  • Patent number: 10413348
    Abstract: An arrangement having a device for providing high-frequency voltage UApp for contact coagulation of the biological tissue. The device is equipped to operate with a high voltage that is normally not suitable for contact coagulation, but otherwise used for spark coagulation, for example, more than 400V at the beginning of the contact coagulation. During the operation of the generator the tissue impedance Z is monitored. This can occur by means of continuously measuring the voltage UApp of the flowing current IApp and the phasing ? between the voltage and the flowing current. Using both, the measuring unit continuously determines the tissue impedance Z. A minimum detector is provided to determine if an impedance minimum Zmin has passed through and if such is found, to induce the generator control to reduce the voltage UApp delivered by the device to a value that avoids spark generation as well as desiccation of the tissue.

  • Patent number: 10314643
    Abstract: 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.

  • Patent number: 10240596
    Abstract: The pump unit (10) has a particularly simple design, which includes just two housing parts (14, 15) and also four valve closure members (37) and pump pistons (25, 29). The valve closure members (37) are preferably identical to one another and are trapped in a pocket between both housing parts (14, 15). The housing parts (14, 15) are preferably permanently interconnected by an ultrasonic weld seam. The valve closure members are formed by disc-like or plate-like plastic parts, which are resilient per se and which may optionally have a central pin (42) as an assembly and orientation aid. As desired, the valve closure members bear against their respective valve seat (43) with or without bias and form valves which open and close particularly reliably, are responsive to the slowest flow velocities and can be easily sterilized.
