    摘要: A trocar sleeve includes a distal tubular section, a section which connects to the distal tubular section at a proximal side of the distal tubular section and which is widened proximally, and at least one spiral with a circular outer contour, arranged helically on a periphery of the distal tubular section. The distal tubular section includes a rounded polygonal cross section so that maximal degrees of freedom of the applied instruments result.

    摘要: A medical instrument has a handle arranged at the proximal end, a shank extending distally proceeding from the handle, and a movable jaw part arranged at the distal end of the shank. The shank is designed to be rigid and includes at least one proximal bend region and at least one distal bend region, in which the extension direction of the shank changes. A section of the shank in which the distal bend region is situated may be rotated about the longitudinal axis relative to a section of the shank in which the proximal bend region is situated. The jaw part is rotatable relative to the shank about its distal longitudinal axis at the distal end.

    摘要: A forceps serves in particular for excising myomas located intramurally in the uterus and including a forceps jaw having two branches which are pivotable about a common axis in a working plane for opening and closing the forceps jaw and which bear against one another with structured gripping surfaces with a closed, empty forceps jaw. The branches are each provided over a part of their length with a tooth-shaped back profile and a longitudinal cutting blade on their outer back sides lying opposite the gripping surfaces.

    摘要: A medical instrument having an inner part which is releasably fastened in the instrument on a proximal end and at the distal end carries a tool which can be actuated by way of an actuation element which is adjustable axially and relative to the inner part and the tool. The actuation element is releasably lockable in a proximal-side, axially adjustable receiver which drives the actuation element at the same time.

    摘要: A flexible or partially flexible endoscope comprising several passages and image guides passing through the shaft has the features that its distal omnilaterally steerable shaft is proximally constructed semirigidly or rigidly, is secured in a coupling element situated on the control housing and is traversed by several image guides which have allocated to them at the proximal control housing several monoculars and/or binoculars via rigid or flexible longitudinal elements. It is possible thereby to replace numerous separate endoscopes by a single endoscope.

    摘要: A trocar sleeve of the kind having a widened part forming a housing between the distal portion of the sleeve and its proximal portion, which latter extends from a plug for the widened housing part, and a ball valve in the widened housing part which ball valve is closable by resilient means and which is openable by a trocar passing through the sleeve.In this invention, the widened part forming the housing receives an insert of U-shaped cross-section which is securable to the plug to stress an inserted sealing gasket of deformation-resistant plastics material which is to be drilled through to form a valve seating. The space in the U formed by the insert forms a space for the ball of the ball valve to move in, the ball, before the insert is screwed to the plug, being connected to a shaft insertable in the insert and carrying a tangentially loaded helical spring and being placed under stress by connecting the insert to the plug.
