    摘要: A medical device comprises an elongate sheath comprising a distal portion and a proximal portion and defining a first lumen. The medical device further comprises an elongate instrument slidably disposed at least partially within the first lumen. The elongate instrument comprises a rigid distal section defining a second lumen. The medical device further comprises a first extension member coupled to a proximal end of the elongate instrument and a second extension member coupled to a proximal end of the elongate sheath. The second extension member is configured to at least partially receive the elongate instrument. The medical device further comprises a holding mechanism coupled to the second extension member. The holding mechanism includes a protrusion configured to maintain the elongate instrument in a rotationally fixed position relative to the distal portion of the elongate sheath.
