  • Patent number: 10492665
    Abstract: Provided is a surgical apparatus for an endoscope that can appropriately and easily perform mounting work of an endoscope onto an outer tube. An outer tube, which passes through a body wall, is inserted into a body cavity, and guides an endoscope and a treatment tool into the body cavity, includes a slider that is an interlocking member that moves the endoscope and the treatment tool forward and backward in an interlocking manner. At the time of mounting of an endoscope in which an endoscope insertion part is coupled to a slider body of the slider, the endoscope insertion part is inserted to a position where a larger-diameter part provided in the endoscope insertion part abuts against a base end surface of an outer tube. Accordingly, the slider body can be coupled to a predetermined suitable position of the endoscope insertion part.

  • Patent number: 10485407
    Abstract: A surgical device, an outer tube, an endoscope, and a treatment tool that have a compact configuration and achieve high durability are provided. The outer tube includes a slider in an outer tube body. When the endoscope and the treatment tool are inserted into the outer tube, and are held by an endoscope holding part and a treatment tool holding part each being provided in the slider, and are combined into a single unit. Consequently, when the treatment tool is moved in the axial direction, the endoscope is moved in the axial direction in interlock with the movement. Because the outer tube is configured such that the endoscope exit port has an inner diameter that is smaller than the inner diameter of the elastic member provided to hold the endoscope at the endoscope holding part, the strength of the endoscope can be secured while preventing interference with the treatment tool.
