Publication number: 20040116952Abstract: A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated using the secondary battery as a driving power source and used to perform surgery on a living tissue. Electromagnetic energy generated by an energy generation unit located outside the surgical instrument is received by a reception coil incorporated in the surgical instrument with the surgical instrument held in noncontact with the energy generation unit. The electromagnetic energy is then converted into charging power with which the secondary battery is recharged. Thus, the surgical instrument can be readily recharged while left clean.Type: ApplicationFiled: December 3, 2003Publication date: June 17, 2004Applicant: Olympus Optical Co., Ltd.Inventors: Tomohisa Sakurai, Shinji Hatta, Akira Shiga, Tsuyoshi Tsukagoshi, Koji Yasunaga, Masaru Karasawa, Hiroyuki Sangu, Takeaki Nakamura

Patent number: 6666875Abstract: A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated or otherwise activated using the secondary battery as a driving power source to perform surgery on a living tissue. Electromagnetic energy generated by an energy generation unit located outside the surgical instrument is received by a reception coil incorporated in the surgical instrument with the surgical instrument by induction from the energy generation unit. The electromagnetic energy is then converted into charging power with which the secondary battery is recharged. Thus, the surgical instrument can be readily recharged without compromising sterility.Type: GrantFiled: January 27, 2000Date of Patent: December 23, 2003Assignee: Olympus Optical Co., Ltd.Inventors: Tomohisa Sakurai, Shinji Hatta, Akira Shiga, Tsuyoshi Tsukagoshi, Koji Yasunaga, Masaru Karasawa, Hiroyuki Sangu, Takeaki Nakamura
