Bougienage cap for medical purposes

A working channel device is mountable on the outer circumference of an endoscope, such as an endoscope of the flexible shaft design. The device has a tubular or hose-like working channel and a distal fixing element that can be fixed to the working channel. The distal fixing element can engage around the endoscope in a clamping manner at the endoscope head of the endoscope. A proximal fixing element can be fixed to the working channel, which can engage around the endoscope, preferably at the endoscope grip of the endoscope. A preferably sleeve-like adapter can be mounted at the proximal end of the working channel of the working channel device. The adapter has or forms the proximal fixing element and additionally forms a connection point/interface for the connection of medical devices.

Endoscope having an additional external working channel

A tissue clip application fitting set or retrofitting set includes a cap attachment for placement on the distal head of a medical endoscope, which has a placement section and a tissue clip holding section. The cap attachment is notched at least at two angular positions forming at least two notches/slots/grooves. A working channel leads into the hollow chamber and exits the hollow chamber radially in a region distal to the placement section and proximal to the radially supported tissue clip. A first guiding or leading element is arranged after the working channel belonging to the retrofitting set, as seen in the distal direction. A corresponding second guiding or leading element is arranged within the hollow chamber at an angular distance from the first guiding or leading element so as to be oriented in extension to a working channel belonging to the endoscope.

Tissue clip application fitting/retrofitting set

The present invention is directed to an endoscopic implant cutting and/or fragmenting apparatus of the bipolar type, operating on direct current, comprising an endoscope instrument having at least two opposing electrodes at its distal instrument head forming a cutting gap inbetween for receiving an electrically conductive implant or implant section to generate punctiform physical contact with the implant, and a DC-impulse generator connected to a control device adapted to generate a direct current in a pulsed way such that in a first phase of physical contact, the current pulse is adjusted to induce electric energy into the implant material being sufficient to melt the implant material exclusively in the area of the contact portion and in a second phase of physical noncontact, the current pulse is adjusted to generate an electric arc between at least one electrode and the melted implant material being sufficient to cut the melted implant material.

Medical DC current generator and bipolar medical implant fragmentation device equipped therewith

The disclosure relates to a spacer in the form of an attachment () to be mounted to an endoscope (), said attachment being formed like a cap, enclosing a spatial volume () and being made of an insulating material. The attachment () is further equipped with a mounting device/adapter () designed to be coupled to a distal end of the endoscope (). The attachment () comprises an area () designed to be in contact with a target tissue and further forms an aperture () enclosing a surface area (). Within the spatial volume, there is arranged an electrode () comprising a distal () and a proximal () end, the distal () end of the electrode () having a predetermined minimum distance to the closest point of the surface area ().

Plasma-surgical apparatus comprising a spacer

A minimally invasive surgical implant-cutting instrument of the bipolar type, operated with direct current, with an instrument head which is located at the distal end of an instrument shank, wherein at least two mutually opposing instrument branches, preferably of the linear type, are arranged on the instrument head and between them define a cutting gap for receiving an electrically conductive implant or implant section between them. The electrodes are formed on the mutually facing longitudinal sides of the branches or these are each equipped with at least one electrode, which electrodes are in turn shaped at their mutually facing longitudinal sides to form a cutting edge in order to effect a quasi-linear or punctiform physical contact engagement with the electrically conductive implant or implant section for an electrical short circuit of the mutually opposing electrodes.

Surgical cutter operated with direct current

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.

Endoscope cap

The invention is directed to an endoscopic retrieval instrument for receiving and retrieving one or more objects from the human body, the instrument comprising an insertion instrument, a retrieval container, and a coupling mechanism configured to selectively disconnect the retrieval container from the insertion instrument.

Medical instrument

The medical implant for treating pathological obesity is adapted to modify and, as an alternative, to bypass the natural food passage in the digestive tract. The implant permits an adjustable bypassing of food into the small intestine and/or into the stomach (natural digestive path). Since the ratio of this bypass is adjustable in the course of the treatment by the physician, e.g. with the aid of an endoscope, for the first time a balance between the therapeutic effect and the side-effects can be adapted individually to each patient by the use of the implant. The implant has a hollow body with first and a second tubular end portions and at least one third lateral opening having a hose-like extension. The individual at least partly closable hose-like extensions differ in their ability to allow the passage of food into the stomach. Closing individual hose-like extensions at least partially by means of an endoscope leads to an individually adjustable distribution of food between the stomach and the small-intestine loop.
