ABSTRACT:
An improved suture threading apparatus is provided which includes an elongated rod having a handle at one of its ends and a needle holder adapted to receive the gripping end of a needle pivotally attached to its other end. The attachment is such that the needle holder may be moved by an actuator between a first position wherein a needle received by the needle holder is held substantially in alignment with the longitudinal axis of the elongated rod, and a second position wherein a needle received by the needle holder is held substantially transverse to the longitudinal axis of the rod. The actuator connects the needle holder to a finger grip substantially adjacent to the handle and includes biasing means which tend to hold the needle holder in its first position in the absence of a force applied to the finger grip overcoming the biasing force to move the needle holder to its second position. A method for using this apparatus to thread suture through tissue also is provided.
