Abstract
A method includes actuating a lever to move a cannula of a medical instrument from a first extended position to second retracted position; and actuating the lever to move a stylet of the medical instrument from a third extended position to a fourth retracted position. Actuating the lever comprises moving the lever from a first lever position spaced apart from a housing of the medical instrument to a second lever position closer to the housing.
Claims11
A method comprising:
- moving a lever from a first lever position spaced apart from a housing of a medical instrument to a second lever position closer to the housing to move a cannula of the medical instrument from a cannula extended position to a cannula retracted position;
- and then
- moving the lever from the first lever position to the second lever position to move a stylet of the medical instrument from a stylet extended position to a stylet retracted position.
A method comprising:
- actuating a lever to move a cannula of a medical instrument from a cannula extended position to a cannula retracted position;
- moving a linkage attached to the lever from a first linkage position in which the linkage is capable of moving the cannula to the cannula retracted position without moving a stylet to a different second linkage position in which the linkage is capable of moving the stylet to a stylet retracted position;
- and
- actuating the lever to move a stylet of the medical instrument from a stylet extended position to the stylet retracted position, wherein actuating the lever comprises moving the lever from a first lever position spaced apart from a housing of the medical instrument to a second lever position closer to the housing.
