The present invention relates to an endoscope cap with a holding and withdrawal device for a tissue clip () that can be placed onto a spreading sleeve () of the endoscope cap (). The endoscope cap comprises an end groove () that opens at the front edge of the spreading sleeve () and that slits open the cap wall on both sides, and a withdrawal thread or web () that radially traverses the end groove () in a forward axial cap section and that is introduced or can be introduced slideably into an endoscope channel for actuation thereof at a radial inside of the endoscope cap ().

Medical gripping device

What is disclosed is an endoscopic surgical instrument with a hose-shaped outside jacket, in which a likewise hose-shaped inside jacket is supported relatively displaceable, on whose distal end section a sleeve or shaft-shaped instrument head is formed or mounted. In the instrument head is fixed a needle-shaped RF electrode electrically-insulated, whose electrical supply line is routed through the inside jacket, and which projects freely beyond the distal end of the instrument head in the axial direction. In the instrument head is formed a flush channel, extending at least axially, opening at both instrument head ends.

Endoscopic surgical instrument

A resection device comprising a cup-shaped cap for a shaft-type inserting means is disclosed which is fixed at the distal end of the shaft-type inserting means or is formed at the same and includes an expanding sleeve portion to which a spring-biased tissue clip is attached which can be withdrawn by means of a releasing or withdrawing device over the distal front edge of the cap. In accordance with the invention, inside the expanding sleeve portion a cutting device is arranged which is held at the inner wall of the expanding sleeve portion at a predetermined axial distance from the distal front edge of the cap.

Resection device

A proctological instrument is disclosed comprising an instrument handle to which at its proximal end a bending-resistant tubular shaft is mounted at the distal end of which a cap is fixed or formed to which a tissue clip adapted to be withdrawn from the cap by means of a releasing or withdrawing device is attached in a preferably spring-elastic manner. In accordance with the invention, the tubular shaft is offset at its distal end portion in an area directly ahead of the cap and/or the cap itself is offset at a predetermined fixed angle so that the withdrawing direction for the clip defined by the cap is aligned at the angle with respect to the tubular shaft axis.

Medical instrument for setting tissue clips

The present application relates to a medical gripping device () with a flexible shaft () with a front end () and a rear end () and a web () comprising at least one web element, wherein the web () is attached to the front end () of the shaft (). The medical gripping device additionally has at least two branches () which are hinged on the web (), and at least two at least partly flexible control mechanisms () which are at least partly arranged in the shaft (), wherein each individual branch () can be moved individually with respect to the web () by means of its individual control mechanism (). Furthermore, the medical gripping device has a grip () at the rear end () of the flexible shaft (), by mans of which grip the medical gripping device () can be held and actuated.
