Patent number: 7828773Abstract: A safety reset key is used to release a locking mechanism holding a safety shield in place over a sharp tip of a needle. In one embodiment, the reset key has ribs that are received in peripheral slots on the safety shield to engage an unlocking mechanism that unlocks a connection of the safety shield to the needle to allow the safety shield to be moved along the needle to expose the sharp tip, such as may be necessary for a second use of the needle. In another embodiment, the reset key includes a shroud that receives the shield to prevent the shield from being inadvertently pulled off of the needle when removing the key. The reset key may be associated with an obturator used to remove biological material from a central axial passageway of the needle.Type: GrantFiled: July 11, 2005Date of Patent: November 9, 2010Assignee: Covidien AGInventors: David R.
