  • Publication number: 20200188009
    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).

  • Publication number: 20200129700
    Abstract: The invention relates to an instrument head, comprising: an exit opening (23); a first feed line (11) for the feed of a first fluid; a second feed line (12) for the feed of a second fluid; a reservoir (24) for storing the fluid fed via the second feed line (12); wherein the reservoir (24) is in fluid communication with the first feed line (11) and/or is adapted to be brought in fluid communication with the first feed line (11) via at least a valve (25) arranged in the instrument head, to deliver fluid stored in the reservoir (24) via the exit opening (23).

  • 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.

  • Publication number: 20200093537
    Abstract: A preparation instrument comprising an HF-instrument with an electrode that is partially insulated by means of an insulating body, which is combined with a fluid applicator having a channel arranged in the insulating body for the application of a fluid to or into tissue. In some embodiments of the preparation instrument, the electrode is a spatula electrode which is inserted in the insulating body that does not cover sections of the surface of the electrode so that these sections may be in contact with the tissue. The insulating body preferably forms the channel wall that delimits the channel. The insulating body and the electrode may be flexible in order to adapt the form of the insulating body and the electrode, together, to the surgical task.

  • Publication number: 20200093999
    Abstract: A medical instrument with an aerosol outlet, which is fluidically connected—via an aerosol line—to a generation device. The generation device is adapted to generate aerosol for dispensing by means of the medical instrument. In addition, a generation device is stated, which, in embodiments of the generation device, for example can be used in a device with the instrument according to the invention. The generation device comprises a mixing unit for mixing a liquid and a gas together, which mixing unit is connected to a liquid container for supplying the mixing unit with a liquid, in which case the generation device is adapted to utilize the gas pressure of a gas under pressure subjecting the liquid to a pressure in order to press the liquid out of the liquid container to the mixing unit.

  • Patent number: 10589299
    Abstract: The invention relates to a method for mixing at least two fluids using an externally mixing nozzle for medical purposes, which has at least two outlet channels (10, 20) and at least two inlet openings (13, 23) with different or identical cross-sections, wherein two fluids with different volumetric flows and/or different viscosity are sprayed, and wherein the ratio of the cross-sections of the inlet channels (13, 23) and/or the outlet channels (10, 20) corresponds to the ratio of the volumetric flows so that the fluids flow with substantially identical flow speeds through the outlet channels (10, 20) and/or the inlet openings (13, 23). The invention furthermore relates to an externally mixing nozzle, a medical instrument and a medical device for spraying substances, in particular biological material.

  • 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: 10569022
    Abstract: The invention relates to a supply system having at least one outlet for connecting to an applicator instrument, and having a controller (51) that controls at least one valve (50, 50?, 50?, 50??) such that, within an application time interval of less than 4 s, in particular less than 2 s: a) a first fluid during at least a first delivery interval (T1) with a first pressure (ph) is conveyed in a first feed line (11); b) a second fluid during a second delivery interval (T2) following the first conveying interval (T1) is conveyed with a second pressure (pz) in a second feed line (23); and c) the first fluid, during at least a third delivery interval (T3), is conveyed with a third pressure (pl) in the first feed line (11).

  • Publication number: 20190090752
    Abstract: The instrument according to the invention for electrosurgically impacting biological tissue comprises an electrode (18) as well as a light guide (21), which is connected to a light inlet window (19), which is formed by means of a fluid body (27). The light guide is connected to a light analysis device (13), so as to absorb the light, which is generated at the electrode (18) in response to the HF surgery and so as to supply it to the light analysis device (13). The light inlet window (19) is arranged at the point of origin of the light, namely immediately at the electrode, that is, at the spark, which is generated. An adulteration of the absorbed light by means of smoke or particle deposition on the light inlet window (19) can virtually be avoided.

  • Publication number: 20180280071
    Abstract: The device and method according to the invention allow a particularly fast, gentle, and secure fusion of vessels between two coagulation electrodes. Resistance oscillations are generated in the biological tissue, said oscillations alternatingly moving above and below a tissue resistance value of, e.g., 50 Ohm. Subsequently, a phase of slowed tissue cooling is passed, during which phase a current is applied to the tissue with chronologically decreasing coagulation voltage to achieve a substantially slowed cooling process compared to the instant voltage disconnection. In doing so, a good fusion of the collagen of the pressed-together vessel walls and a mechanically stable solidification of the collagen is achieved. Due to the mentioned process control, the required fusion time is shortened compared to conventional methods, the unwanted damage to surrounding tissue is reduced, and the closure of the vessel is more secure.
