May 6, 1997

Appl. No.:

8/851650

Inventors:

Thomas D. Guy - Hobe Sound FL

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

B23P 1300
B21G 100

US Classification:

29 565

Abstract:

There is disclosed an apparatus for forming curved and rectangular bodied needle blanks from a length of needle stock which includes a generally cylindrical inner mandrel having a plurality of longitudinal channels formed in an outer surface thereof, the mandrel being dimensioned and configured for insertion within the length of needle stock. The apparatus also includes a plurality of broaches insertable into the longitudinal channels such that an edge of each broach projects radially outwardly of the mandrel to form a plurality of inner grooves on an inner surface of the length of needle stock. There is also provided structure for forming outer grooves in an outer surface of the length of the needle stock to form a substantially grooved length of needle stock, cutters for cutting the grooved length of needle stock to form rings of curved rectangular bodied needle blanks interconnected by web portions and structure for dividing the rings at the web portions to form a plurality of curved rectangular bodied needle blanks. There is also disclosed a method of forming needle blanks from a length of needle stock having a longitudinal cavity therethrough and defining a longitudinal axis by forming at least two inner grooves in an inner surface of the length of needle stock and substantially parallel to the longitudinal axis, forming a number of outer grooves, equal to the number of inner grooves, in an outer surface of the length of needle stock and in substantial radial alignment with the at least two inner grooves to form a grooved length of needle stock and sectioning the grooved length of needle stock to form individual needle blanks.
