摘要：
A puncture sleeve includes a trocar filler and a trocar sleeve. The trocar sleeve includes a trocar cannula and a trocar housing, the trocar cannula including a first open end and a second open end coupled to the trocar housing, The trocar housing includes a first portion and a second portion, the first portion includes a first annular surface, a first locking structure and a positioning block, and the second portion includes a second annular surface and a second portion a locking structure and a blocking block, the second portion having a rotational trajectory relative to the first portion, the blocking block of the second portion being elastically from the blocking trajectory by the positioning block The one side of the positioning block spans to the other side to fix the first portion and the second portion to each other, thereby achieving a securely coupled structure.一種穿刺套筒，包括一套管針充填器及一套管針套筒。該套管針套筒包括一套管針套管及一套管針殼體，該套管針套管包括一和該套管針殼體連接的第一開放端及一第二開放端，該套管針殼體包括一第一部分及一第二部分，該第一部分包括一第一環面、一第一鎖固結構及一定位塊，該第二部分包括一第二環面、一第二鎖固結構以及一擋止塊，該第二部分相對該第一部分具有一轉動軌跡，該第二部分的該擋止塊於該轉動軌跡之中受該定位塊的擋止而受迫彈性地從該定位塊一側跨越至另側使該第一部分和該第二部分彼此固定，藉此達穩固結合的結構。
