The apparatus includes a frame for positioning and maintaining the needle while the suture is being attached and a rotating die system which selectively impacts the needle to secure the suture thereto. ## Claims ### Claim 1 Apparatus for attaching a surgical suture to an eyeless needle comprising: support means; die means having a die cartridge with at least one jaw slidably secured thereto, said die means supported by said support means for selectively impacting the needle such that a portion of the needle is deformed to maintain the suture therein, said die cartridge being rotatable between at least two positions relative to said support means; first drive means associated with said support means for actuating said at least one jaw to impact the needle in at least one of said two positions; and second drive means associated with said support means for rotating said die cartridge at least to a second of said two positions relative to said needle. ### Claim 2 (depends on 1) The apparatus according to claim 1 further comprising needle gripping means associated with said support means for maintaining the needle in a predetermined position when said die means is actuated. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein said die means impacts the needle in said first and second positions. ### Claim 4 (depends on 3) The apparatus according to claim 3, wherein said second position is oriented at least a predetermined angular position from said first position. ### Claim 5 (depends on 4) The apparatus according to claim 4, wherein said second position is oriented at least about 90.degree. from said first position. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein said die cartridge comprises: gear means secured to said die cartridge and operatively connected to said second drive means for translating movement of said second drive means to rotational movement of said die cartridge. ### Claim 7 (depends on 6) The apparatus according to claim 6, wherein said second drive means comprises rack gear means secured to a second drive member and adapted for engagement with said gear means of said die cartridge such that linear movement of said rack gear means causes rotational movement of said die cartridge. ### Claim 8 (depends on 1) The apparatus according to claim 1, wherein said first drive means comprises: a first pair of arms pivotally connected to a first drive member and positioned adjacent said die cartridge on opposite sides thereof; and a second pair of arms pivotally connected to said first drive member and positioned adjacent said die cartridge on opposite sides thereof and out of phase with said first pair of arms. ### Claim 9 (depends on 1) The apparatus according to claim 1 further comprising guide means positioned adjacent said die means for guiding the suture into a bore in the end face of the needle. ### Claim 10 (depends on 9) The apparatus according to claim 9, wherein said guide means includes means for adjusting the position of said guide means in at least two directions. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein said at least two directions are respectively horizontal and vertical. ### Claim 12 (depends on 1) The apparatus according to claim 1 further comprising control means operatively connected to said first and second drive means for selectively activating said first and second drive means. ### Claim 13 (depends on 12) The apparatus according to claim 12, wherein said control means comprises pneumatic and electrical controls of said first and second drive means. ### Claim 14 (depends on 12) The apparatus according to claim 12, wherein said control means includes switch means for automatically terminating said impacting and said rotation of said die means during an emergency condition. ### Claim 15 Apparatus for attaching surgical suture components comprising: a frame; needle gripping means secured to said frame for gripping a drilled surgical needle and for maintaining the needle in a predetermined position; die means supported by said frame adjacent said needle gripping means, said die means having a die cartridge with at least one jaw slidably secured thereto for selectively impacting said needle so that a portion of said needle is deformed sufficient to maintain the suture therein, said die cartridge being rotatable relative to said frame; first drive means associated with said frame for actuating said die means to impact the needle; and second drive means associated with said frame for rotating said die means after the needle is impacted to facilitate impacting the needle from a direction which differs from said direction of said first impact. ### Claim 16 (depends on 15) The apparatus according to claim 15, wherein said die means impacts the needle in first and second positions. ### Claim 17 (depends on 16) The apparatus according to claim 16, wherein said second position is a predetermined rotated distance from said first position. ### Claim 18 (depends on 17) The apparatus according to claim 17, wherein said second position is 90.degree. from said first position. ### Claim 19 (depends on 16) The apparatus according to claim 16, wherein said second drive means rotates said die means between said first and second positions. ### Claim 20 (depends on 15) The apparatus according to claim 15, wherein said die cartridge comprises: gear means secured to said die cartridge and operatively connected to said second drive means for translating movement of said second drive means to rotational movement of said die cartridge. ### Claim 21 (depends on 20) The apparatus according to claim 20, wherein said second drive means comprises a rack gear attached to a second drive member and engaged with said gear means such that linear movement of said rack gear causes rotational movement of said die cartridge. ### Claim 22 (depends on 15) The apparatus according to claim 15, wherein said first drive means comprises: a first pair of arms pivotally connected to a first drive member and positioned adjacent said die cartridge on opposite sides thereof; a second pair of arms pivotally connected to said first drive member and positioned adjacent said die cartridge on opposite sides thereof and out of phase with said first pair of arms. ### Claim 23 A method for attaching surgical suture components which comprises: providing a die cartridge having a pair of dies supported by said die cartridge such that at least one of said pair of dies is slidable relative to the other; releasably securing a surgical needle having a bore in an end face, between said pair of dies; orienting said die cartridge and said needle to a first position; inserting a surgical suture into said needle bore; impacting said needle with said pair of dies so as to secure said suture to said needle; rotating said die cartridge a predetermined rotational amount until said dies are oriented at an angle relative to said first orientation; and impacting said needle with said pair of dies so as to further secure said suture to said needle. ### Claim 24 (depends on 23) The method according to claim 23, wherein said die cartridge is rotated 90.degree..
