Abstract: An endoscopic surgery apparatus is provided, including a tubular member, a handle located on a proximal end of the tubular member, and one or more pivotable arms detachably connected to a distal end of the tubular member. The tubular member has channels along its longitudinal axis, wherein at least one of the channels is an optical channel and at least one other channel is an illumination channel. The arms have guiding channels adapted to receive surgical tools, which direct the surgical tools. The arms are interchangeable with other arms of different configurations. Also, said arms have an open and a closed position, such that when the arms are in the closed position an opening is defined allowing viewing of a surgical site via the optical channel.

Abstract: A system for orientation assistance and display of an instrument that is inserted or present in the natural or artificially produced hollow cavity (human, animal, object), and that is equipped with one or more sensor units. Multiple measurements of the 3D position of the instrument equipped with one or more sensor units are performed by positioning a measuring system, so that a precise orientation and positioning of the instrument in the body can be computed. The 3D position data are used to compute a virtual image of the instrument synchronously. The virtual images are then either projected directly in exact position onto the body surface of a person or combined in a body surface image (real video camera image of the patient) onto a monitor or superimposed (virtual or augmented reality). The system is especially appropriate for displaying for a user a medical instrument, such as a catheter or a rigid or flexible endoscope, in the body of a person in real time, extracorporeally and in correct position.

Abstract: A method of transluminal surgery is provided, which utilizes an endoscopic surgery apparatus having pivotable arms attached by hinges on its distal end. The arms are interchangeable with arms of various configurations. The method includes the steps of inserting an endoscopic surgery apparatus into a body cavity of a patient, making an incision in the body cavity wall to allow access to the patient's abdominal cavity, and further inserting the apparatus through the incision. Surgery is performed at the desired surgical site and the apparatus is withdrawn into the body cavity where the incision is closed. Finally, the apparatus is withdrawn from the patient's body.

Abstract: An endoscopic surgical instrument is provided that includes a handle portion, an elongated middle portion, an articulating portion and a tool portion. The tool portion is steerable by control mechanisms disposed on the handle portion which are accessible to a single hand of a user of the endoscopic surgical instrument. The endoscopic surgical instrument is advantageously employed in a variety of endoscopic surgical techniques, including transgastric or transluminal surgery.

Abstract: A rectoscope has a tube and a handle protruding therefrom. A number of light-emitting elements are arranged circumferentially distributed at the distal end of the tube. The tube includes an inner pipe, an outer pipe and an annular body at the distal ends of the inner and outer pipe. The annular body includes an end ring provided with bores for receiving the light-emitting elements. The annular body also includes an annular flange extending away proximally and having an outside diameter corresponding to a clear inside diameter of the outer pipe. The end ring has an outside diameter corresponding approximately to an outside diameter of the outer pipe.

Abstract: The invention relates to an endosurgical extraction bag for collecting body tissue or body fluid, with a bag main part formed from a flexible envelope, and with a first admission opening for introducing tissue or fluid into the bag main part of the bag. Arranged in the bag main part, there is an inner envelope which is connected to the main part (bag) and opens toward the first admission opening, but adjoins the bag main part sealingly in respect of the first admission opening, and which has a second admission opening at its second end remote from the first admission opening and spaced apart from an end of the bag main part remote from the first admission opening, through which second admission opening the tissue or fluid can be introduced into the bag main part.
