Patent number: 6202898Abstract: With this device the fluid is located in a container which can be set under pressure, into which two cannulas of differing lengths may be inserted. A short cannula, via a gas conduit and a release valve, is connectable to a pressurised gas source in order to impinge the container above the fluid level with pressurised gas, whilst the other longer cannula is connectable to a fluid conduit leading to the instrument and protrudes into the fluid located in the container. The fluid flow to the instrument is interruptable with a blocking element and the pressurised gas supply to the container is interruptable with the release valve. Such a device may be simply constructed and used when, according to the invention, the cannulas, the blocking element and a control valve are grouped together into a constructional unit on which there is located one connection for the gas conduit and a further connection for the fluid conduit.Type: GrantFiled: April 15, 1999Date of Patent: March 20, 2001Assignee: Richard Wolf GmbHInventor: Guido Koch

Patent number: 6152870Abstract: An endoscope comprises a hollow shank, optic viewing means positioned in the hollow shank for observing a body cavity, and a separate adjustable instrument channel which is axially, slidably arranged in an internal guiding region of the hollow shank. The instrument channel has a flexible curvature section and a laterally running end section with an end portion that is pivotably and articulably mounted in a radial passage in the distal circumferential wall region of the hollow shank. Sliding the instrument channel axially in the hollow shank results in flexing of the curvature section and pivoting of the end portion, such that an auxiliary instrument provided in the instrument channel is laterally deflected when guided through the hollow shank.Type: GrantFiled: June 26, 1998Date of Patent: November 28, 2000Assignee: Richard Wolf GmbHInventor: Jorg Diener

Patent number: 6061591Abstract: The invention relates to an arrangement and method for diagnosing malignant tissue by fluorescence observation with an endoscope. A stroboscope is used as a white light source in order to illuminate the interesting tissue region through the endosocope. A laser is simultaneously used in order to stimulate the fluorescence. At a time, the analyzer is activated in the dark phase between two light flashes of the stroboscope and deactivated during a visible light flash. The tissue, with a continuous fluorescence stimulation by exposure to light with a stimulating wavelength, may be observed under a pseudo-white light. The spectrogram may be represented on a screen which displays a normal white light endoscopic picture.Type: GrantFiled: March 24, 1997Date of Patent: May 9, 2000Assignee: Richard Wolf GmbHInventors: Lutz Freitag, Franz Dankwart-Eder

Patent number: 6044855Abstract: The invention is concerned with a device and a method for cleaning and disinfecting medical instruments, in particular instruments of minimal invasive surgery (MIS). Instead of the rigid connection of cleaning tubings to instrument connections and exits which has been used up to now and which have the disadvantage that certain contaminated regions remain inaccessible for a secure cleaning, there is suggested a docking of injector nozzles in defined chronological intervals, the injector nozzles being fixed in a centric position to the openings of the instrument connections. At the same time various types of injector nozzles are applied for adaptation to various instrument connections and openings. By measuring the rinsing fluid quantity flowing to the instrument connections and the total discharging rinsing fluid quantity, the quality of preparation may be evaluated and documented.Type: GrantFiled: November 12, 1997Date of Patent: April 4, 2000Assignee: Richard Wolf GmbHInventor: Harry Monch
