  • Patent number: 11730530
    Abstract: The inventive device (10) can be used for tissue coagulation and/or tissue ablation. It comprises at least one electrode (16) that serves for generating a spark or plasma jet and is connectable to an electric source (20) for this purpose. The probe (11) is assigned to a measuring device (24) that emits and/or receives light in the proximity of the electrode (16) and determines the distance of the probe (11) from the tissue (36) and/or the tissue temperature and/or the composition of the influenced tissue (36). Preferably the measuring device (24) is operated synchronized with pulses or pauses of the pulse-pause-modulated radio frequency voltage (UHF) of the electrode (16) in order to simultaneously carry out the desired measurements during the operation of the instrument (11) and to feedback control the operation of the instrument (11) based on the gained measurement results.

  • Publication number: 20230172651
    Abstract: A theragnostic system includes a surgical station and a storage and processing device that contains data in a suitable storage in which patient data and treatment data, e.g. in form of electrical and optical features, are combined. The electrical features are derived from electrical parameters of the voltage and the current with which an instrument is supplied. The optical features are derived from light of the spark that is produced upon influencing the tissue. By combining electrical and optical features in a data collection, that even contains additional features, such as tissue features and patient characteristics, it can be determined whether the instrument influences benign or malign tissue. The prediction accuracy can be increased by machine learning by adding histological data to the data sets. These data can be collected in a cloud computing system that is connected with many surgical stations.

  • Patent number: 11357406
    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.

    Abstract: A device for creation of a plasma-activated liquid with defined characteristics. The device includes a plasma application device having a plasma applicator. A liquid is brought into contact with a gas plasma in the plasma application device. A sensor device serves for analysis of the composition of the plasma-treated liquid at least in terms of a species created by the plasma treatment. Based on a concentration of one or more species detected by the sensor device, treatment parameters of the liquid in the plasma application device can be adjusted or modified. Thereby a plasma-treated liquid with defined characteristics for treatment of a patient is provided.

  • 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.
