Patent number: 7056304Abstract: The invention relates to a medical instrument with a hollow instrument canal that is configured inside a housing and can be closed by means of at least one valve body and rotated into open position by means of an instrument inserted into the instrument canal. The at least one valve body is configured as a flap consisting of an essentially non-bendable material mounted on the housing so that it can be rotated by means of an elastic, bendable connecting element configured as a wire spring in such a way that the valve body is pre-tensioned in the closed direction. A medical instrument with a valve body of simple construction, which insulates reliably, is distinguished according to the invention in that the connecting element on the one hand is secured on the housing and on the other hand carries the valve body, so that the connecting element can be secured in a ring groove configured in the housing.Type: GrantFiled: February 24, 2003Date of Patent: June 6, 2006Assignee: Karl Storz GmbH & Co. KGInventors: Uwe Bacher, Horst Dittrich, Martin Oberlaender

Patent number: 6991621Abstract: A medical instrument for irrigation and/or suction has an instrument body in which at least one flow channel is present for the passage of a fluid, at least one shut-off member for alternately shutting off the at least one flow channel, and an actuating member for actuating the shut-off member. The at least one shut-off member is a ball which, in a closure position, lies sealingly on a sealing edge of the flow channel so that it closes off the internal cross section of the flow channel, the ball being movable, between the closure position for closing the flow channel and a release position for freeing the flow channel, substantially in a direction transverse to the longitudinal direction of the flow channel, and the actuating member for moving the ball between the closure position and the release position being movable in a direction transverse to the flow channel.Type: GrantFiled: January 21, 2003Date of Patent: January 31, 2006Assignee: Karl Storz GmbH & Co.

Patent number: 6945983Abstract: A trocar sleeve comprises at its proximal side a housing, from the distal side of which a shaft projects. Further, a sealing of elastic material is provided in order to seal an instrument inserted into the trocar sleeve gas-tight into the proximal direction. The sealing comprises a central opening, the diameter of which is variable. A spreading device is provided which is insertable into the sealing, extending same in doing so, whereby the diameter of the central opening is enlargeable. It is suggested to configure the spreading device as an axially movable sleeve, the ring-shaped front area of which is insertable into the sealing, spreading same in doing so.Type: GrantFiled: October 26, 2001Date of Patent: September 20, 2005Assignee: Karl Storz GmbH & Co. KGInventors: Horst Dittrich, Michael Sauer, Martin Oberlaender

Patent number: 6699185Abstract: An endoscopic instrument is provided comprising a shaft having an endoscope optical system arranged therein, which has a distal front face. The instrument also comprises a working element arranged in the shaft. The shaft provides for the supply of an irrigation fluid. Flow-influencing means are provided, such that the irrigation fluid reaches in front of the front face of the endoscope optical system and can eliminate contaminations, which obstruct the view through the endoscope optics.Type: GrantFiled: September 10, 2001Date of Patent: March 2, 2004Assignee: Karl Storz GmbH & Co.
