Abstract
An embroidering tool has an adjustable needle penetration capability and is formed from two interfitting components that are relatively rotatable about a common axis to provide the adjusting movement. One part has a cannulation needle assembly in accord with certain aspects of the invention and which at the proximal end of the needle thereof is encased in a plastic member which is a molded plastic product provided with an exterior flat screw thread. The other component is a unitary unmodified molded plastic structure with an interior wall that has a protuberance which is engaged by the thread of the outer part in the assembled structure of the tool. The two components snap together when they are assembled although modifications are contemplated to facilitate separate use of the needle carrying component from the other component.
