Method for providing disc nucleus replacement in a spine

The present invention is a safety syringe for use with a plurality of interchangeable needles. The plurality of needles may be inserted by the user into the safety syringe for use. In operations, the user selects the desired needle, e.g., a needle having a particular gauge or size or of a particular type. The user inserts the needle () into a safety syringe () comprising a barrel (), a needle assembly area () located within or attached to the barrel and a plunger (). The needle couples to the syringe by a number of means. For instance, a locking mechanism () may be used by which a needle hub located within the needle assembly has an area adapted to mate with a corresponding area on the needle. Or, the needle may be formed as part of a separate needle assembly, whereby the user will place the entire needle assembly onto the end of the syringe barrel. During use, the user operates the syringe like other safety syringe, using one hand to depress the plunger, which ultimately causes a spring to propel the needle into the barrel of the syringe.

A syringe apparatus and process is provided for retracting a needle from a hypodermic syringe following the completion of an injection. The hypodermic syringe has a plunger which, upon completion of the injection, is forced downwardly against a needle support deformable base, severing sacrificial supports. An end portion of the needle tears a base portion of the plunger and propels the needle into a hollow region of the plunger such that the needle is contained entirely within the plunger.

Safety syringe

A syringe apparatus and process for using the same is provided, the syringe apparatus having a barrel, a plunger movable within the barrel, a needle assembly attached to an end of the barrel and having a passageway therethrough, a deformable base positioned within the barrel, flexible supports included on the deformable base, a spring within the passageway of the needle assembly, a hollow needle passing through the passageway, an enlarged head on the needle, and a rupturable web on an end of the plunger, whereby when the plunger moves through the barrel toward the needle assembly, a fluid can be moved from the barrel through the hollow of the needle, and continued movement of the plunger flexes the supports and moves the deformable base downwardly until such time a sufficient force is imparted to the rupturable web by the enlarged head to tear the web, the deformable base then releasing the needle due to force applied by the spring to project the needle into the interior of the plunger. Seals are provided for making a liquid impervious seal on both ends of the syringe after the needle is retracted. The seal on the end left open by needle retraction is a closing member which can be used to seal off the opening without placing a user's hands in front of the opening. The syringe includes indicia that is revealed upon needle retraction to label the syringe as a biohazard. A syringe apparatus using a deformable base, enlarged needle head and needle assembly of an alternative embodiment is also provided wherein sacrificial supports in the needle assembly are utilized and severed by the deformable base.
