Rotational needle

Abstract

An apparatus for rotating a needle comprising an inner sleeve securable to a syringe barrel, the inner sleeve having an inner sleeve passage extending therethrough, an outer sleeve rotatably supported by the inner sleeve, the outer sleeve having an outer sleeve passage extending therethrough in fluidic communication with the inner sleeve passage, the outer sleeve having a needle receptacle adapted to receive and operably couple a needle thereon, and a rotational energy-storing device, operably connected to the inner and outer sleeve so as to provide a rotational torque therebetween. A method for rotating a needle comprising rotating the outer sleeve relative to the inner sleeve so as to store rotational energy within the rotational energy-storing device extending between the inner and outer sleeves and releasing the outer sleeve such that the needle rotates relative to the syringe barrel.
