摘要：
A medical needle protector apparatus (100； 200) comprising: a first housing (52； 236) and a second housing (54； 268), the first housing having a needle cannula (4； 206) disposed therewith, the the needle cannula arranged for sliding movement with the second housing, so that the second housing is extensible from a retracted position to an extended position, to enclose a distal end of the needle cannula； a connecting member (40； 256), arranged within the second housing and comprising connecting surfaces (68) defining an opening (66) configured for sliding reception of the needle cannula between the retracted position and the extended position , a retention device (72) extending therefrom, such that the retention device can engage with the needle cannula to prevent tilting of the connecting member while the retention device is engaged with the needle cannula, and one or more resistance promoting members (62) that engage the needle cannula during sliding reception of the needle to create a resistance force with the needle, facilitating the resistance force and the second housing tilting the connection member with respect to a longitudinal axis of the needle cannula once the retention device extends beyond the distal end of the needle, so that the connection surfaces engage the needle cannula to prevent sliding displacement of the needle cannula in the extended position of the second housing, characterized in that the first housing is configured to drive the needle cannula, the cannula Needle includes an internal needle arranged for sliding movement with the needle cannula and the first housing includes a drive mechanism that drives the needle cannula； and in that the second housing can be releasably engaged with the first housing by means of a release device (30, 31, 32, 38, 114； 17, 33, 41, 43, 55； 274, 276, 278), such that activation of the operable release device selectively releasably blocks displacement between the needle cannula and the inner needle.Un aparato (10
