Patent number: 10413375Abstract: An instrument, particularly a medical endoscopic instrument or technoscope, includes a shank (2) and an instrument head (6). The instrument head includes at least one joint part (12) articulated on the distal shank end in an angularly bendable manner and a tool carrier (14) which at the distal side is articulated on the joint part (12) in an angularly bendable manner in the angular bending plane of the joint part (12). A toothing is meshed with a toothed body (26) rotatably mounted in the shank (2) and is coupled in movement to a pull cable pair for the movement control of the instrument head (6).

Patent number: 9763559Abstract: An endoscope with an instrument housing and with a shaft that is mounted on the distal end of the instrument housing and consists of an outer tube and an inner tube that is mounted at least partly in the outer tube, so that the outer tube and the inner tube are mounted on the instrument housing so that they can move with respect to one another in the axial direction of the shaft. To provide an endoscope that ensures a constantly fluid-tight relative motion of the two shaft tubes with respect to one another, it is proposed with the invention that the outer tube and inner tube should be mounted on the instrument housing so that they are mobile with respect to one another in the axial direction of the shaft by means of at least one flexible membrane.Type: GrantFiled: August 13, 2010Date of Patent: September 19, 2017Assignee: Karl Storz GmbH & Co.

Publication number: 20150366573Abstract: An instrument, particularly a medical endoscopic instrument or technoscope, includes a shank (2) and an instrument head (6) which is arranged at a distal shank end. The instrument head (6) is bendable relative to the shank and includes a tool with two jaw parts (12, 14) which can be pivoted relative to one another.

Publication number: 20150265355Abstract: An endoscopic instrument for the connection to an operation robot. The endoscopic instrument includes an instrument housing, to which a shank with at least one instrument part arranged at the distal side of the shank connects distally. The instrument part and/or the shank are movable relative to the instrument housing and for this are each actively connected to control. The control can be coupled, via a translatorily movable coupling element coupled thereto and projecting out of the instrument housing, to a linear drive unit which can be connected to the instrument housing at the outer side.Type: ApplicationFiled: March 17, 2015Publication date: September 24, 2015Inventors: Stephan PRESTEL, Sören Münnig, Elmar TEICHTMANN, Frank WEHRHEIM

Publication number: 20150202013Abstract: A medical instrument includes a shaft that includes at least two adjacent shaft sections which are movable relative to one another. The at least two movable shaft sections are engaged with each other so as to roll off one another in a frictionally locking manner or so as mesh with each other via teeth.Type: ApplicationFiled: July 24, 2013Publication date: July 23, 2015Inventors: Elmar Teichtmann, Frank Wehrheim

Patent number: 8668711Abstract: A medical instrument has a cannula and a seal disposed in the cannula. An expansion device serves for expanding an opening in the seal for guiding shafts of other instruments of greater diameter in a sealed manner through the expanded opening. The expansion device has an expansion cone with a plurality of slats mounted pivotably on an annular body at a first end thereof, a second end of the slats being connected to the seal in an area of the opening. The slats are connected at its first ends to the annular body via spherical heads engaged into corresponding openings in the annular body.Type: GrantFiled: June 3, 2013Date of Patent: March 11, 2014Assignee: Karl Storz GmbH & Co. KGInventors: Elmar Teichtmann, Michael Sauer

Patent number: 8603133Abstract: The invention relates to a medical instrument having a hollow shaft, a tool positioned on the distal end of the shaft consisting of a rigid jaw member and a jaw member that can rotate with respect to the rigid jaw member, as well as a handle positioned on the proximal end of the shaft. The tool and the handle are in active connection with one another by a push-pull rod mounted in the shaft, and the jaw members of the tool are mounted on one another by pins. It is proposed with the invention that the push-pull rod should be configured as a hollow slide tube mounted in the shaft so that it can slide axially and is in active connection with the rotatable jaw member by an actuation element that is essentially rod-shaped.Type: GrantFiled: November 29, 2007Date of Patent: December 10, 2013Assignee: Karl Storz GmbH & Co.
