Abstract: An endoscope including: a handle; an insertion cord extending from the handle and including at least a distal tip; a working channel which during suction is configured to let a fluid and a mucus and a clot suctioned from the patient's body cavity flow therethrough; and a clot dissecting channel which is configured to eject a fluid stream for dissecting the clot before or while the clot enters the working channel, the clot dissecting channel being directed towards and opening up towards the working channel or a distal extension of the working channel in the distal tip.

Abstract: An endoscope including a handle including an aperture and a valve insert arranged in the aperture; the valve insert including: a first valve cylinder having a first cylinder wall, a second valve cylinder having a second cylinder wall, and a flange connecting and spacing apart the first valve cylinder and the second valve cylinder. The flange is arranged in the aperture of the handle. Portions of the first valve cylinder and of the second valve cylinder are arranged inside the handle and include a plurality of tube ports.

Abstract: The forceps instrument includes a central pull-push member formed by transmission and actuating elements. The central push-pull member opens and closes the branches, and also acts as a tissue abutment that is variable based on the degree of closure of the branches. The variable tissue abutment may be configured as a slider element and is adjustable proportionally to the opening angle of the branches. When grasped, the vessels are brought proximally. The tissue abutment acts as a spacer between the hinge region and the grasped material. While the branches are being closed, the vessel is held stationary and compressed. During compression, expansion of the vessel occurs axially in distal and proximal directions. Due to the receding of the variable tissue abutment during the closing operation, room is created for the grasped material to escape. Tissue accumulations can thus be restricted and overstressing of the tissue can be counteracted.
