An interior cooled ablation instrument includes a curved section adjoining its distal end in which the ablation instrument is bent relative to its axial direction. The amount of the angle is preferably defined to one-third up to two-thirds, and preferably half of the maximum angulation. The maximum angulation can significantly exceed an absolute value of 140°. Due to the pre-bend in the curved section, a kinking of the hose of the ablation instrument and thus an impairment of the electrode cooling as well as the occurrence of high dam pressure can be effectively avoided. In doing so, the ablation instrument allows a freer work, even more considerably oriented at medical aspects and considerations compared to completely stretched ablation instruments.

Preferably the closure device is controlled pneumatically by means of the liquid or gaseous fluid flowing inside channel. With this measure a contamination of the light passage window during operation of the instrument can be reliably avoided or at least reduced to a minor degree.

This remarkably increases treatment safety.

The RF voltage required for supply of a surgical instrument is thus composed of individual impulses. The same applies for the current flowing at the electrode of the instrument.

The electrode is either directly secured on the conductor or the conductor is provided with a plastic sheathing at least at its distal end by means of which the electrode is held. The electrode can be inserted between the conductor and the plastic sheathing and can be clamped in this manner. After first use the plastic sheathing can be fused to the electrode. The conductor is placed with clearance inside a channel or hollow space of electrode, however, whereby also in case of spot-like contact between the conductor and the electrode due to the gap provided between them apart therefrom the heat transmission from the electrode on the conductor is impeded and thereby the heat introduction in the plasma probe is limited.
A knife cartridge for use in a surgical instrument. The knife cartridge includes a blade that can be operated by a second operating element. The blade is held in a blade housing that can be transferred from a first locking position (passive position) into a second locking position (active position) by a first operating element. In the passive position the blade housing is completely located inside the cartridge housing and the blade is locked therein. In the active position the blade housing projects out of the cartridge housing. Only in the active position a locking between the blade housing and blade can be released, whereby also only then a driving connection is established between the second operating element and the blade.

The input transistors (33, 35) of cascode circuits (31, 32) are cross-coupled, whereas the control electrodes of the output transistors (34, 36) are connected with non-varying potential. The power oscillator (22) is self-controlled such that the transistors (33-36) comprise lowest switching losses.

An instrument (10) that is usable for tissue fusion and cutting includes a counter support (22) configured as a thin membrane that is assigned to a cutting electrode (17) arranged between two electrode pairs. The thin membrane is spanned in a frame (25) on which it is held with its circumferential surface in a substance bond manner. The circumferential surface thereby extends in an angle, preferably in a right angle, relative to the coagulation electrodes (28, 29) formed by the frame top side. The pressing force applied by the membrane with which biological tissue (32) is pressed against cutting electrode (17) is thus predominantly created by the tensile stress present in the membrane.
