  • Publication number: 20070213745
    Abstract: The ligating apparatus has the thread receiving portion 50 movably disposed back and forth at the distal end of the inserting part body. Outer circumference of the thread receiving portion 50 forms the loop holding portion 52 around which the knot forming loop 51 formed from the ligature 40 is disposed. When the first end of the ligature 40 is pulled into the thread receiving portion 50, the knot forming loop 51 is pushed out of the loop holding portion 52 by the delivery portion 62 of the knot pusher 59. The knot forming loop 51 is further pushed by the delivery portion 62 along the ligature 40 toward the tissue W1 and ligated. The present invention provides a ligating apparatus capable of reducing the load on the tissue to be ligated during ligating operation.

  • Patent number: 6791604
    Abstract: An electronic camera of the present invention includes a paper exit opening for removal of printed paper provided on the upper surface of the case of the camera main body, a protection sheet having a base end fixed to the inside of the paper exit opening, with a free end revertible to a wound-up roll shape retracted inside the case, and capable of being extended by the front end of the printed paper when the printed paper is transported from the case to the outside so that the protection sheet covers the photosensitive surface of the paper, and an open-and-close lid having one end edge axially supported to be rotatable to the case so that the paper exit opening is closed from the outside of the case when the protection sheet is retracted within the case. Further, the protection sheet includes a linking mechanism for linking the protection sheet to the open-and-close lid so that the open-and-close lid is opened or closed interlocked with a movement of the protection sheet.
