The tip components of the medical device, an endoscope cleaning sheath and an endoscope system using the endoscope cleaning sheath

摘要

The present invention aims at providing a front end component of a medical device capable of suppressing catching the like during removal of the medical device with a simple configuration, therefore, the convex formed on the outer periphery of substantially circular and the outer peripheral portion a shape consisting of a part 12b having a possible inner diameter to accept the member 12 to the outer diameter shape, and a proximal end 11x having an outer diameter formed on the outer diameter shape substantially similar shape, the maximum outer diameter of the proximal portion and it is essential to outright toward the tip portion from above or the front end portion 11y of the substantially cylindrical shape having an outer diameter of the maximum outer diameter substantially the same diameter of the proximal portion, is formed in a portion corresponding to the convex portion base end portion and it is formed with a notch and a portion 11b of the shape.
