    摘要: A cannula insertion tool having a needle movable between a retracted position and an extended position. In some embodiments, the needle can be retracted within the periphery of a handle of the insertion tool when not in use to protect the needle. When the needle is needed for surgical use, the needle can be extended at least partially beyond the outer periphery of the handle. The needle can be coupled to a slide movable relative to the handle between the retracted position and the extended position. The slide can be secured in each position to prevent unintentional movement of the slide. A cannula can be positioned on the needle when the needle is in the retracted position, and can be retained upon the needle by a member extending toward the cannula.

    摘要: An electrical component has a housing received in a receiving groove, which is confined by opposite lateral walls connected to a groove bottom, formed in a support. A retaining device includes a base extending from one end of the housing and disposed on the groove bottom of the receiving groove, an engaging block confined non-rotatably in the receiving groove and disposed between the base and opposite stop protrusions that are formed respectively on the lateral walls and that cooperate to form a restricted access into the receiving groove, and a fastener extending rotatably through a through hole in the engaging block and coupled rotatably to the base. Operation of the fastener can drive the engaging block to move to an engaging position, where the engaging block abuts against the stop protrusions and where the fastener urges the base toward the groove bottom.
