  However, in the conventional endoscope sterilization tray, the in-vivo insertion tube portion guide groove is simply configured to be loosely fitted into the in-vivo insertion tube portion, and the in-vivo insertion tube portion of the in-vivo insertion tube portion guide groove Since the surface comes into surface contact with the bottom surface, the insertion tube portion in the body is not sufficiently sterilized with the sterilization gas at that portion, and the endoscope taken out from the sterilization apparatus may not always be completely sterilized.

  Therefore, an object of the present invention is to provide an endoscope sterilization tray capable of placing an endoscope stored in a sterilization apparatus so that the sterilized state does not become partially insufficient.

  In order to achieve the above object, the endoscope sterilization tray of the present invention is placed when the endoscope having a configuration in which the operation unit is connected to the proximal end of the body insertion tube unit is stored in the sterilization apparatus. In the endoscope sterilization tray, the body insertion tube portion guide groove into which the body insertion tube portion is loosely fitted and the operation portion fitting groove into which the operation portion is loosely fitted are respectively formed in a state of being recessed from the surface portion. A linear or dotted projection for placing the in-vivo insertion tube portion fitted in the insertion tube portion guide groove is formed to project upward on the bottom surface of the in-vivo insertion tube portion guide groove.

  The linear protrusions may be formed near the center position of the bottom surface of the in-vivo insertion tube portion guide groove along the longitudinal direction of the in-vivo insertion tube portion guide groove, and the linear protrusions are spaced apart in the longitudinal direction. Between the plurality of linear protrusions formed on the bottom surface of the in-vivo insertion tube portion guide groove, a drain hole penetrating the back side of the bottom surface of the insertion tube guide groove is formed. May be.

  In addition, a linear or dot-like protrusion for placing the operation part fitted in the operation part fitting groove may protrude upward from the bottom surface of the operation part fitting groove. On the side surface, a linear or dot-like protrusion may be formed so as to protrude inward of the in-vivo insertion tube portion guide groove. The linear or dotted protrusions formed on the side surface of the in-vivo insertion tube portion guide groove may be disposed alternately on both side surfaces of the in-vivo insertion tube portion guide groove. The linear protrusion formed on the side surface of the guide groove may be formed along the circumferential direction of the in-vivo insertion tube portion guide groove.

In addition, when the protrusions of the linear or dot-like projections are formed in a rounded surface, the contact portion with the endoscope becomes an extremely fine linear shape, and a more complete sterilization process can be performed.
In addition, the in-vivo insertion tube portion guide groove may be formed to be branched into a plurality of parts in the middle, and the in-body insertion tube portion of any type of endoscope is fitted into the in-vivo insertion tube portion guide groove. It is good to be comprised so that the front-end | tip of a part may be located in the linear part of a body insertion tube part guide groove.

  According to the present invention, a linear or dotted projection for placing the in-vivo insertion tube portion fitted in the in-vivo insertion tube portion guide groove is formed to protrude upward on the bottom surface of the in-vivo insertion tube portion guide groove. Since the contact area of the in-vivo insertion tube portion with respect to the tray can be made extremely small, the endoscope can be placed so that the sterilized state is not partially insufficient.

  In-body insertion in which an insertion tube part is loosely fitted in an endoscope sterilization tray for placing an endoscope having a configuration in which an operation part is connected to the proximal end of the insertion tube part in a sterilization apparatus.
