  • Patent number: 5833697
    Abstract: A surgical instrument for holding a suture needle is provided. The instrument is of a scissors configuration with elongated arms having finger loops at one end and jaws at the other end to grasp a suture needle. This improved instrument has specialized jaws containing a transverse channel that securely holds a suture needle at a right angle to the axis of the needle holder jaws. The width of the transverse channel adjusts to the size of the suture needle by means of a cam and spring loaded camming surface which move a sliding member against the side of a suture needle as the jaws of the needle holder are closed. This improved configuration significantly reduces the long standing problem of suture needle twisting or rotation in the needle holder jaws as the surgeon passes the needle through tissue.
