Claims

[Scope of utility model registration request]

(1) In an endoscope provided with an insertion channel for guiding a puncture needle having a hard seal at its tip, the insertion channel is formed at the tip of the insertion section, communicates with the insertion channel, and houses the seal. An endoscope characterized by having a storage opening for storing the contents.

(2) An abutting protrusion is provided at the end of the storage opening on the endoscope proximal side, which hits the puncture needle and prevents the seal of the puncture needle from entering the endoscope proximal side. An endoscope according to claim 1 of the utility model registration claim.

(3) The endoscope according to claim 1 or 2, which is characterized in that it is provided with a resistance means that prevents the forward and backward movement of the puncture needle.
