  • Publication number: 20190167075
    Abstract: 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.

  • 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: 20190038333
    Abstract: 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.

  • Publication number: 20180338791
    Abstract: The instrument comprises a jaw arrangement with two jaws that have, on their side facing the counter-electrode arrangement, rounded or flat electrode surfaces. The counter-electrode arrangement comprises at least one counter-electrode surface that may be rounded or flat. One of the electrode surfaces has a band edge preferably bordered by an insulator on one side, said band edge being adjacent to the adjacent electrode surface of the jaw arrangement. The counter-electrode surface has a band edge adjacent to the insulator facing the band edge of the one electrode surface. The band edges of the electrode surfaces acting as the coagulation surfaces are close enough such that they form cutting edges that develop a cutting effect with low voltages that are otherwise suitable only for coagulation. Accordingly, it is possible to provide fusion instruments that are extremely delicate, display lower thermal inertia and an excellent fusion and cutting effect.

  • 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.

  • Patent number: 9980767
    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 tunneling, endoscopic mucosa resection, etc).

  • Publication number: 20180140342
    Abstract: 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.
