摘要：
Catheter and needle assemblies with spring-powered retractable needles are described. The assemblies can include a hollow handle, a grip portion, a catheter hub with a catheter, and a needle. The needle can have a first position in which the needle is slidably disposed within the catheter and a second position in which the needle is slidably removed from the catheter and retracted at least in part into the hollow handle. The grip portion can include a trigger portion that activates a spring to move the needle from the first position into the second position. In the second position, a sharp distal point of the needle is shielded by the grip portion to prevent accidental needle sticks.
