Abstract: An instrument for plasma treatment of biological tissue comprises plasma exit windows in the form of openings having an edge extending obliquely relative to the longitudinal direction (L), which can be formed by flank of a web. The webs taper in radial direction (+R) and are preferably obliquely inclined relative to the longitudinal direction (L). The webs support a proximal section of the instrument head and connect the latter seamlessly monolithically with a proximal part of the head. Due to the outward tapering of the webs, their shading effect is minimized or eliminated.

Abstract: An instrument according to the invention for plasma treatment of biological tissue comprises plasma exit windows in form of openings, which widen or taper in longitudinal direction. In doing so, inclined positions of webs result, which are present between the individual openings and which seamlessly monolithically connect a proximal section of the instrument head with a distal section. Due to the inclined position of the webs, the shading effect is minimized or eliminated.

Abstract: An endoscopic instrument having an instrument body configured in a long, slim and flexible manner. The instrument may be completely or partly wound in one or more windings that allows the instrument to be packed in a space-saving and easy-to-handle manner. To keep the instrument body in this position, a holding device is provided that is arranged on the instrument body and is preferably undetachably held there. The holding device has a gripper rotatably supported around the instrument body. The instrument body has a latch to hold and fasten the windings.
