ABSTRACT:
An improved surgical needle of the type having a simple main cutting edge extending across the needle and formed by the intersection of two planar surfaces for use in cutting through hard body tissue material. The forward end of the needle includes a relatively small third substantially planar surface having an acute angle of convergence with the axis of the needle and intersecting at substantially equal acute angles with the other two planar surfaces. The surgical needle is preferably curved in the reference plane defined by the main cutting edge and the axis of the needle. Such an improved surgical needle results in an extremely sharp needle with a high resistance to burring.
