Patent ID: 8690879

Claim:
A reducer system comprising: a polyaxial screw receiver having a rod-locking channel; and an elongated tubular member having a generally helical reducer channel, said elongated tubular member being adapted and configured to mount onto said polyaxial screw receiver; said generally helical reducer channel receiving a rod and causing said rod to move in said generally helical reducer channel along an axis of said elongated tubular member and toward said rod-locking channel of said polyaxial screw receiver in response to a rotation of said elongated tubular member, an inner diameter at an end of said elongated tubular member being larger than an outer diameter of said polyaxial screw receiver so that said end of elongated tubular member can be situated circumferentially around said polyaxial screw receiver; said rod-locking channel of said polyaxial screw receiver extending along a channel length from a top of said polyaxial screw receiver toward a bottom of said polyaxial screw receiver; at least a portion of said elongated tubular member being adapted to extend over and at least partially surround said polyaxial screw receiver so that said end of said elongated tubular member extends past said top of said polyaxial screw receiver towards said bottom of said polyaxial screw receiver along said channel length so that when said generally helical channel receives said rod, said rod is urged to move into said rod-locking channel in response to rotation of said elongated tubular member.
