Surgical instrument with pivotable implant holder

A surgical instrument for inserting an implant, the surgical instrument comprising:

• a housing having a longitudinal axis, a proximal end and a distal end, said housing having a through slot extending through said distal end of said housing;
• a rotatable member rotatably positioned in said housing, said rotatable member having an elongated member extending between said proximal end and said distal end of said housing and comprising a grip generally located at said proximal end of said housing;
• an implant holder connected to said elongated member of said rotatable member, said implant holder having a spherical or rounded head having a spherical or rounded external surface that mates with or engages a spherical or rounded internal wall surface of said housing at said distal end and a securing member comprising a threaded projection monolithic with said spherical or rounded head, said threaded projection extends through said through slot in said distal end of said housing and is configured to engage with and hold said implant;
• a universal joint coupling said implant holder to said elongated member;
• said universal joint situated in said housing between said grip and said threaded projection, said universal joint allowing said implant holder to be rotatably driven about a longitudinal axis of said implant holder when said threaded projection is in a pivoted position at which said axis of said implant holder is not coaxial with said longitudinal axis of said housing;
• wherein said universal joint comprises a ball and socket joint that is rotatable within said distal end of said housing, said ball and socket joint comprising:
• a spherical or rounded socket defined within said spherical or rounded head of said implant holder;
• a distal end of said elongated member having a ball that is received in said spherical or rounded socket, said ball having at least one through aperture extending therethrough;
• at least one pivot pin having a pivot in axis extending through said at least one through aperture of said ball;
• said at least one pivot pin pivotally coupling said ball in said spherical or rounded socket of said implant holder, such that said pivot in axis of said at least one pivot in is not coaxial with said longitudinal axis of said housing when the ball is coupled in said socket and said threaded projection is in said pivoted position;
• said pivot pin rotatably driving said spherical or rounded socket about said longitudinal axis of said implant holder in response to rotation of said rotatable member about an axis of said elongated member being coaxial with said longitudinal axis of said housing and permitting said implant holder to pivot relative to said ball about said pivot pin axis of said at least one pivot pin, so that said securing member pivots to said pivoted position at which said axis of said implant holder is not coaxial with said longitudinal axis of said housing;
• and
• an abutment member pivotally and adjustably coupled to said housing, said abutment member being external to said distal end of said housing, said abutment member comprising:
• an abutment member first surface matingly connected or engaged to an external surface of said distal end of said housing when said implant is in a clamped, fixed or locked position with said housing,
• an abutment member second surface against which said implant configured to be driven in order to clamp, fix or lock said implant into a clamped, fixed or locked position relative to said housing,
• an abutment member through aperture extending through said abutment member first and second surfaces through which said threaded projection extends,
• said abutment member being pivotally adjustable relative to said distal end of said housing and being adapted to be clamped, fixed or locked to said distal end of said housing while in said pivoted position in response to said threaded projection being rotatably and threadably received in a threaded opening in said implant which causes said implant to be driven against said abutment surface and causes said abutment member first surface to engage said distal end of said housing;
• wherein said abutment member first surface and said distal end of said housing have a plurality of teeth or serrations that matingly engage or matingly connect with one another to prevent further pivotal movement of said abutment member and said implant relative to the housing when said abutment member is coupled, fixed or locked to said distal end of the housing;
• wherein said abutment member further comprises a plurality of flanges for pivotally coupling said abutment member to said housing so that said abutment member can pivot relative to said distal end of said housing,
• a connection for coupling said plurality of flanges and said distal end of said housing together, said connection comprising at least one pin or projection having an axis and at least one opening configured to receive said at least one pin or projection so as to couple a first end of said plurality of flanges of said abutment member to said distal end of said housing;
• wherein at least one of said distal end of said housing or said first end of at least one of said plurality of flanges includes the at least one pin or projection and the other includes the at least one opening,
• said connection permitting said abutment member to move longitudinally relative to said axis of said implant holder towards said distal end of said housing when said threaded projection is secured into said implant and permitting said abutment member to pivot about the axis of the at least one pin or projection of said connection, thereby enabling said abutment member to be releasably and adjustably secured to said distal end of said housing.
