Patent number: 7063692Abstract: A plurality of handpieces used to perform an operation is connected to a main operation apparatus, which generates a driving signal, through connectors formed on the main apparatus. When an operator holds a handpiece he/she wants to use, an output line over which the driving signal is transmitted is routed to the held handpiece owing to an output of a sensor that detects a change in capacitance stemming from the hold. The operator therefore need not manually set a mode in which the driving signal is applied to the handpiece he/she wants to use. Moreover, a port number assigned to a port to which the output line is routed is indicated on a display device. The operator can readily identify the usable handpiece.Type: GrantFiled: July 28, 2003Date of Patent: June 20, 2006Assignee: Olympus CorporationInventors: Tomohisa Sakurai, Hiroyuki Takahashi, Masaru Sudo, Takeaki Nakamura, Keiji Shioda, Takashi Ozaki, Makoto Miyawaki

Patent number: 6716160Abstract: The endoscope has a frame member for satisfying at a time, mechanical strength chemical resistance, size reduction, weight reduction, and workability by using carbon fiber reinforced thermoplastic resin as a frame member disposed inside the endoscope. The frame member of an at-hand operating part is formed by using carbon fiber reinforced thermoplastic resin. In the carbon fiber reinforced thermoplastic resin, substantially 20% to substantially 30% of carbon fiber is contained in a mixed material prepared by mixing crystalline resin and amorphous resin in a ratio of substantially 7:3 to substantially 8:2.Type: GrantFiled: February 12, 2002Date of Patent: April 6, 2004Assignee: Fuji Photo Optical Co. Ltd.Inventor: Naotake Mitsumori

Patent number: 6714839Abstract: The invention provides an input device for robotic surgical techniques and other applications. The input device has a handle supported by a linkage having joints with a redundant degree of freedom, with the joints being movable with at least one more degree of freedom than the handle. At least one joint of the linkage is actively driven to prevent the linkage from approaching singularities of the joint system, motion limits of the joints, or the like, and also to drive the linkage toward a freely articulatable configuration. In one embodiment, a robotic master controller includes an arm assembly supporting a gimbal having such a redundant linkage, with the arm primarily positioning the gimbal in a three dimensional controller workspace and the gimbal coupling the arm to the handle with four rotational degrees of freedom. One or more additional degrees of freedom may also be provided for actuation of the handle.Type: GrantFiled: September 17, 1999Date of Patent: March 30, 2004Assignee: Intuitive Surgical, Inc.Inventors: J. Kenneth Salisbury, Jr., Akhil J. Madhani, Gary S. Guthart, Günter D. Niemeyer, Eugene F. Duval

Patent number: 6679838Abstract: A micro-endoscopic system employs a pulsed xenon light source and novel image collection optics with a fine diameter optical probe for an endoscope. Very bright pulses of light emitted by a xenon flash tube increase the intensity of light incident on the light transmitting optics, allowing a reduction in size of the optical components, resulting in a corresponding reduction in the size of the optical probe. A novel segmented glass image guide directs the reflected light to a sensor array. Segmentation of the image guide avoids the birefringence problems associated with fine diameter glass optical structures. Conventional optical fiber imaging and light delivery apparatus may also be used in conjunction with the pulsed xenon light source.Type: GrantFiled: January 5, 2001Date of Patent: January 20, 2004Assignee: Micro-Invasive Technology, Inc.Inventor: John L. Bala

Patent number: 6648815Abstract: A medical instrument for endoscopic removal of the saphenous vein has an elongated shaft which hat at the distal end a spatula tip and in whose proximal region is arranged a laterally projecting handle. The instrument further has an endoscopic optical system which has an eyepiece cup that is arranged at the proximal end of the instrument. The handle is joined to the shaft in such a way that an outer side of the instrument facing away from the handle continuously has a surface that, from the distal to the proximal end, is free of projections. The eyepiece cup is arranged in oblique orientation with respect to a longitudinal center axis of the shaft and encloses with the handle, with respect to the longitudinal center axis, an angle of less than 90°.Type: GrantFiled: March 28, 2002Date of Patent: November 18, 2003Assignee: Karl Storz GmbH & Co.
