Problems solved by technology

[0006] In addition, the use of shielded wires creates the problem that the shielded wire is preferably grounded, and this connection to ground causes leakage currents at the point where the patient comes into contact with grounded conductive parts; in particular, these leakage currents can become become larger and larger, which in turn will have an adverse effect on the outcome of the operation and also represent a danger to the patient

Embodiment Construction

[0017] figure 1 Shown is a schematic circuit diagram of a high-frequency surgical device 1 according to the present invention. The high-frequency surgical device 1 has a high-frequency generator 3 and a surgical instrument 5, and the surgical instrument 5 may be, and here is only a suggestion, for example, a surgical instrument for coagulation of biological tissue plasma. The surgical instrument 5 has an active electrode AE, which is located close to the tissue 6 to be treated. In addition, a neutral electrode NE is provided on the tissue 6 to be treated, and the electrode NE is used to return the current flowing through the patient to the high-frequency generator 3, and for this reason, the patient is in contact with the electrode NE.

[0018] The active electrode AE ​​of the surgical instrument 5 is connected to the high-frequency generator 3 through the first wire 7 to provide high-frequency current. The neutral electrode NE is also connected to the high-frequency generator 3...

Abstract

The unit (1) has a surgical instrument (5) e.g. bipolar instrument, comprising active and neutral electrodes (AE, NE) and connectable with a high frequency (HF) generator (3) over a spacer (7). The neutral electrode is connected with the HF generator over another spacer (9), where the spacers are provided with shields (11, 13), respectively. Decoupling capacitors (Cae,Cne) are arranged at a distal end of each spacer, where the shields of the spacers are grounded over a common ground path (15). A current measurement device (17) measures leakage current (Ileck) flowing via the path.

Description

Technical field [0001] The present invention relates to a high frequency surgical device described in the preceding claim 1. Background technique [0002] The high frequency surgical equipment described in this application is well known. The high-frequency surgical device has a high-frequency generator and at least one surgical instrument, and the surgical instrument has an active electrode connected to the high-frequency generator through a wire for providing high-frequency current. In addition, a neutral electrode for return current is provided, and the neutral electrode is connected to the high-frequency generator through a corresponding second wire in a similar manner. [0003] The high-frequency generator described in this application generates high-frequency voltages or currents, and transmits them to connected surgical instruments through corresponding wires. The surgical instrument may be a monopolar, bipolar or quasi-bipolar instrument for cutting and / or coagulating biol...
