Abstract
An apparatus for forming at least one curved, rectangular bodied surgical needle which comprises frame means, flat press means associated with said frame means for imparting first flat surfaces to opposite sides of at least a portion of at least one needle blank, curving means associated with said frame means for imparting an arcuate profile to at least a portion of the at least one needle blank and side press means mounted on said frame portion for imparting second flat surfaces to opposite sides of the needle blank, wherein said second flat surfaces are imparted substantially perpendicular to said first flat surfaces. There is also disclosed a method of forming a curved rectangular bodied needle from a substantially round-elongated needle blank comprising the steps of flat pressing opposite sides of the needle blanks between a pair of flat press dies, drawing the needle blanks from at least one of said flat press dies onto a rotatable mandrel, curving the needle blanks between said rotatable mandrel and a reciprocable belt, rotating the needle blanks adjacent side press dies and depositing the needle blanks therebetween and side pressing opposite sides of the needle blanks between said side press dies, on sides of the needle blanks substantially perpendicular to the flat pressed sides. A surgical needle is also disclosed having a tapered distal portion, a rectangular central portion and a bored proximal portion formed according to the apparatus and method described above. The tapered distal portion of the needle has a generally circular cross-section, the rectangular central portion is generally square and the bored proximal portion also has a generally circular cross-section.
