ABSTRACT:
A device for performing an anesthesia procedure on a patient comprising, a needle assembly having an elongated hollow needle with a distal tip, and a connecting member attached to a proximal end of the needle, with the connecting member having an elongated distally directed control member generally aligned with and spaced from the needle. The device has a sleeve assembly having an elongated hollow sleeve to slidably receive the needle, and an abutment member attached to a proximal end of the sleeve. The abutment member has a first proximal stop member to abut against a distal portion of the control member in a configuration of the needle assembly at a first rotational position with the needle tip retracted within the sleeve assembly, and a guide device to releasably retain the needle assembly at the first rotational position. The abutment member has a second intermediate stop member to abut against the distal portion of the control member in a configuration of the needle assembly at a second rotational position with the needle tip extending an intermediate distance from the sleeve assembly, and a guide device to releasably retain the needle assembly at the second rotational position. The abutment member has a third distal stop member to abut against the distal portion of the control member in a configuration of the needle assembly at a third rotational position with the needle tip extending a maximum distance from the sleeve assembly, and a guide device to releasably retain the needle assembly at the third rotational position.
