Patent number: 7645245Abstract: An endoscopic lithotripsy probe apparatus includes a probe, ultrasonic-vibration source, mechanical shock generation source, and switch-mechanism. The ultrasonic-vibration source is detachably attached to the probe to transmit an ultrasonic-vibration to the probe in a state in which the proximal end of the probe is connected to the ultrasonic-vibration source. The mechanical shock generation source, which is disposed on the side of the proximal end of the probe, applies a force to the ultrasonic-vibration source in a state in which the ultrasonic-vibration source is detached from the proximal end of the probe, and allows the ultrasonic-vibration source to collide with the proximal end of the probe so that a mechanical shock is applied to the probe. The switch-mechanism switches a state in which the ultrasonic-vibration from the ultrasonic-vibration source is transmitted to the probe and a state in which the mechanical shock from the mechanical shock generation source is transmitted.Type: GrantFiled: December 4, 2003Date of Patent: January 12, 2010Assignee: Olympus CorporationInventors: Naomi Sekino, Tsuruo Hatori, Koji Shimomura, Hiroshi Okabe, Shinji Hatta, Hiroo Ono, Tomohisa Sakurai, Takeaki Nakamura

Patent number: 7270646Abstract: An ultrasonic driving apparatus consists mainly of a digital oscillatory circuit, an amplifier, a detection circuit, a phase difference detection circuit, a register, a data transfer circuit, and a switching circuit. The digital oscillatory circuit is used to drive an ultrasonic transducer at the resonance frequency of the ultrasonic transducer. The amplifier amplifies a driving signal output from the digital oscillatory circuit. The detection circuit detects the phase ?v of an applied voltage and the phase ?i of an induced current from the driving signal applied to the ultrasonic transducer via the amplifier. The phase difference detection circuit detects a difference between the phases ?v and ?i. The register holds digital frequency data with which a frequency at which the digital oscillatory circuit is oscillated is determined, and changes the digital frequency data. The data transfer circuit transfers the digital frequency data to the register.Type: GrantFiled: February 9, 2004Date of Patent: September 18, 2007Assignee: Olympus CorporationInventors: Tomohisa Sakurai, Yoshitaka Honda, Kazue Tanaka, Hiroo Ono, Hiroyuki Takahashi

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
