Patent number: 11064867Abstract: A medical-endoscopic shank instrument includes a hollow shank (2), a distal side housing (8) in the hollow shank, an electronic picture sensor (14) and/or a light located in the housing. The housing is linearly movable to move the picture sensor and/or the light from within an inner lumen (22) of the hollow shank to outside the inner lumen. The housing is displaceable through an opening (20) formed on a peripheral wall of the hollow shank. An inner-lying outer side (26), opposite and away from the opening, is formed on a peripheral wall of the hollow shank and is supported on an elongate carrier (32) which is guided in the hollow shank. The elongate carrier (32) is configured elastically resiliently transverse to longitudinal extensions thereof and extends essentially over a whole length of the hollow shank and is fixed in a region of the proximal end/proximally of the hollow shank.Type: GrantFiled: August 29, 2016Date of Patent: July 20, 2021Assignee: RICHARD WOLF GMBHInventors: Sebastian Frey, Friedrich Hähnle, Eberhard Körner

Patent number: 10828063Abstract: A medical instrument includes a proximal handle (3), for controlling a distal tool, including two grip pieces (4, 5) pivotable relative to one another, subjected to spring force and coupled in movement via a path guide with a path component (7). The path component includes a guide path (11), and a guide body (14) on a guide component (8). The guide body engages into the guide path. The components (7, 8) are arranged on one of the grip pieces and are subjected to a spring force, transversely to a pivoting plane of the grip pieces. One of the components (8) is pivotably arranged on a grip piece. Functionally independent of the guide body (14) and guide path (11), a latching body (12) is received by a latching receiver (16) on the components (7, 8) for a latching function, blocking pivoting movement of the grip pieces.Type: GrantFiled: March 9, 2018Date of Patent: November 10, 2020Assignee: RICHARD WOLF GMBHInventors: Carina Amann, Friedrich Hähnle, Eberhard Körner

Publication number: 20180263656Abstract: The medical instrument comprises a proximal handle (3) for controlling a distal tool. The handle (3) comprises two grip pieces (4, 5) which are arranged in a pivotably movable manner relative to one another, are subjected to spring force and are coupled in movement to one another via a path guide (11, 14), wherein the path guide (11, 14) comprises a path component (7) which comprises a guide path (11), and a guide body (14) on a guide component (8), said guide body engaging into the guide path (11). The components (7, 8) are arranged on one of the grip pieces (4, 5) and are subjected to spring force to one another transversely to a pivoting plane of the grip pieces (4, 5). One of the components (8) is pivotably arranged on a grip piece (4, 5). At least one latching position, in which the pivoting movement of the grip pieces (4, 5) is blocked in one direction, is formed between the components (7, 8).Type: ApplicationFiled: March 9, 2018Publication date: September 20, 2018Inventors: Carina AMANN, Friedrich HÄHNLE, Eberhard KÖRNER

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. The instrument head (6), for controlling bending, is coupled in movement to at least one actuation rod (26). The actuation rod (26) is displaceably guided in the shank (2) in a shank longitudinal direction. For the control of the tool, the two jaw parts (12, 14) are coupled in movement to at least one pull cable which is led through the shank (2) to a proximal instrument end.Type: ApplicationFiled: February 4, 2014Publication date: December 24, 2015Inventors: Friedrich HÄHNLE, Elmar TEICHTMANN, Frank WEHRHEIM, Matthias LAMBERTZ, Eberhard KÖRNER, Manfred BOEBEL

Publication number: 20090292170Abstract: A stereo-endoscope is provided having a hollow shank with two axially parallel optical channels, which channels run through the hollow shank and respectively form at least a section of an image path to respective oculars of a binocular observation device arranged on the proximal end of the hollow shank. Moreover, the stereo-endoscope includes a camera connection, and one of the optical channels also forms at least one section of an image path to the camera connection.Type: ApplicationFiled: May 19, 2009Publication date: November 26, 2009Applicant: RICHARD WOLF GMBHInventors: Manfred BOEBEL, Alexander FRANK, Klaus-Peter HIPP, Rudolf HEIMBERGER, Felix BITROLF, Friedrich HAHNLE, Carl-Sebastian WAGNER, Stephan PRESTEL, Gerhard Fritz BUESS

Publication number: 20010021853Abstract: The instrument serves the application in particular of bone grafts in the space between two vertebrae and consists of a shank, of a handle and of a holder for the implant, which forms the distal instrument part. The holder is pivotably mounted relative to the shank and can be fixed in its position which in each case is reached by pivoting.Type: ApplicationFiled: March 9, 2001Publication date: September 13, 2001Applicant: RICHARD WOLF GmbHInventors: Helmut Heckele, Friedrich Hahnle, Eberhard Korner

Patent number: 5800398Abstract: An instrument for positioning operating tubes in endoscopic operations. A distally pointed cannula tube serves as a guiding probe for introduction into a patient's body so that the distal end is disposed closely proximate the operating site, and carries a handle that is removably attached to the cannula tube proximal end. The cannula tube is hollow for receiving therethrough a mandarin. The mandarin and tube handle are removed from the cannula tube once the tube is inserted into the patient's body, thus leaving only the cannula tube extending into the body of the patient to serve as a guiding probe for one or more operating tubes.Type: GrantFiled: April 25, 1996Date of Patent: September 1, 1998Assignee: Richard Wolf GmbHInventors: Friedrich Hahnle, Helmut Heckele, Uwe Schaumann
