Biopsy needle device |
摘要 |
A medical needle shield apparatus is provided that includes a first housing configured to actuate a needle cannula. A second housing is releasably engageable with the first housing. The needle cannula is disposed for slidable movement with the second housing such that the second housing is extensible from a retracted position to an extended position to enclose a distal end of the needle cannula. The second housing includes a binding member that defines binding surfaces that form an aperture configured for slidable receipt of the needle cannula. The binding member includes a drag inducing member that engages the needle cannula during slidable receipt of the needle cannula to create a drag force. The drag force and second housing facilitate rotation of the binding member relative to a longitudinal axis of the needle cannula such that the binding surfaces engage the needle cannula to prevent slidable movement of the needle cannula.
