Abstract
A medical instrument includes a housing, a stylet having a portion in the housing, a cannula coaxially receiving the stylet and having a portion in the housing, and a member slidably coupled to the housing. The stylet and the cannula are movable between an extended position and a retracted position. The member is configured with primary and secondary bars to move the stylet and the cannula from their extended positions to their retracted positions.
Claims19
A medical instrument, comprising:
- a housing;
- a stylet having a portion in the housing, the stylet being movable between an extended position and a retracted position;
- a cannula coaxially receiving the stylet and having a portion in the housing, the cannula being movable between an extended position and a retracted position;
- and
- a single member slidably coupled to a surface of the housing that actuates both the cannula and the stylet, the member configured to move sequentially the cannula from the extended position to the retracted position, and the stylet from the extended position to the retracted position.
