  • Publication number: 20040116952
    Abstract: 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.

  • Patent number: 6666875
    Abstract: 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.

  • Patent number: 5702352
    Abstract: A tool for manipulating tissue includes a penetration needle adapted to be stuck into a body cavity of a patient. A pulling device is insertable into a hollow portion of the penetration needle so as to be positioned in the body cavity of the patient when the penetration needle is stuck therein. The pulling device is adapted to pull tissue in the body cavity and the penetration needle is adapted to be removed from the body cavity after the pulling device is positioned therein. A manipulating device having a hollow portion through which the pulling device can be passed is adapted to be guided over the pulling device to be inserted into the body cavity of the patient after the penetration needle is removed therefrom. The manipulating device is adapted to be positionally fixed relative to the pulling device and to be operable together with the pulling device to move the pulled tissue in a desired direction and to hold the pulled tissue at a desired position.
