  • Patent number: 10402006
    Abstract: An information processing apparatus includes a touch sensor configured to detect a touch position on an input surface touched with a pointer. The information processing apparatus is configured to receive, depending on whether or not a linear locus of the touch position on the input surface starts from inside an operation start region set on the input surface, the linear locus of the touch position as any one of a first operation and a second operation different from the first operation on an image that is displayed on a predetermined display. The operation start region is determined based on at least one of an operation status of the pointer and a display state of the image.

  • Patent number: 10245011
    Abstract: Disclosed is a hemostatic agent applicator capable of effectively placing a fluid hemostatic agent on an incision surface. The present invention is a hemostatic agent applicator for use in disposing a fluid hemostatic agent, including a tool body in which a hollow part surrounded by a wall part is formed and which includes an open end part on a downstream side of the wall part, and an inlet provided to a portion of the wall part of the tool body to communicate with the hollow part. This hemostatic agent applicator is useful in medical settings relating to surgical procedures, particularly for surface bleeding of a liver and internal organ surgery such as a spleen and fibroid enucleation. An applicator further reduced in size can be applied not only in abdominal surgery, but in endoscopic surgery as well.
