Abstract
The utility model provides a round tube shaped stapling instrument and a guiding device thereof. The round tube shaped stapling instrument comprises a stapling barrel assembly and the guiding device detachably mounted on the stapling barrel assembly. The guiding device is integrally a spiral structure formed by surrounding of spiral lines and comprises a guiding portion arranged outside the stapling barrel assembly. An outer profile of the guiding portion shrinks from the near end to the far end. The guiding device further comprises recesses and protrusions which are arranged on opposite sides of two adjacent spiral lines and used for mutually positioning and matching. The recesses and the protrusions are used for mutually matching and positioning when the round tube shaped stapling instrument extends into a human body and are mutually separated to gradually disintegrate the guiding portion spirally when the guiding portion is pulled by external force.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of tubular type binding instrument and guiding device thereof.
