Surgical needle with recessed features
View Patent ↗A surgical needle is adapted for use with a circular needle applier having a needle driver. The surgical needle comprises an elongate body curved along a circular arc in a plane. The elongate body has a leading end, a trailing end, a longitudinal axis between the leading and trailing ends, a cross-sectional circumference, an upper face, a lower face, a medial face, and a lateral face. A pair of recessed features on the body are adapted to be engaged by a needle driver. A pair of protuberances are adjacent each recessed feature. The protuberances are longitudinally coincident with the respective recessed feature and circumferentially offset from the respective recessed feature. The protuberances project outwardly from the body.
1. A surgical needle adapted for use with a circular needle applier having a needle driver, the surgical needle comprising:
an elongate body curved along a circular arc in a plane, the elongate body having a leading end, a trailing end, a longitudinal axis between the leading and trailing ends, a cross-sectional circumference, an upper face, a lower face, a medial face, and a lateral face;
a first recessed feature on the medial face of the body adapted to be engaged by a needle driver;
a first pair of protuberances projecting outwardly from the upper and lower faces of the body, the first pair of protuberances being longitudinally coincident with the first recessed feature;
a second recessed feature on the medial face of the body adapted to be engaged by a needle driver, the second recessed feature being located at the antipodal point of the circular arc relative the first recessed feature; and
a second pair of protuberances projecting outwardly from the upper and lower faces of the body, the second pair of protuberances being longitudinally coincident with the second recessed feature.
