Abstract
A rod insertion device for inserting a rod into a bone anchor includes a shaft having a first end, a second end, and a shaft axis; a rod holding member connected to the first end of the shaft and configured to pivot relative to the shaft about a pivot axis and to receive a portion of a rod therein, the rod holding member comprising at least two recesses in an outer surface of the rod holding member and separated from each other along a circumferential direction about the pivot axis; a handle at the second end of the shaft; a locking member configured to lock an inserted rod in the rod holding member; and a detent member configured to selectively engage the rod holding member to latch a pivot position of the rod holding member relative to the shaft.

A rod insertion device for inserting a rod into a bone anchor, the rod insertion device comprising:
- a shaft having a first end and a second end and a shaft axis;
- a rod holding member connected to the first end of the shaft and configured to pivot relative to the shaft about a pivot axis and to receive a portion of a rod, the rod holding member comprising at least two recesses in an outer surface of the rod holding member;
- a handle at the second end of the shaft;
- and
- a detent member configured to selectively engage the at least two recesses of the rod holding member to latch the rod holding member in at least two different pivot positions relative to the shaft.
A rod insertion device for inserting a rod into a bone anchor, the rod insertion device comprising:
- a shaft having a first end and a second end and a shaft axis;
- a rod holding member connected to the first end of the shaft and configured to pivot relative to the shaft about a pivot axis and to receive a portion of a rod therein;
- a handle at the second end of the shaft;
- a locking member configured to lock an inserted rod in the rod holding member;
- and
- a detent member configured to selectively engage the rod holding member to latch a pivot position of the rod holding member relative to the shaft,
- wherein, in a first locked state, the locking member extends into the rod holding member, and
- wherein, in a second locked state in which the rod holding member is pivoted to be in a position different than in the first locked state, the locking member extends further into the rod holding member than in the first locked state.
A method for inserting a rod into a bone anchor using a rod insertion device, the rod insertion device comprising a shaft having a first end and a second end and a shaft axis;
- a rod holding member connected to the first end of the shaft and configured to pivot relative to the shaft about a pivot axis and to receive a portion of a rod, the rod holding member comprising at least one recess in an outer surface of the rod holding member, an axis of the at least one recess being parallel to the pivot axis;
- a handle at the second end of the shaft;
- a locking member configured to lock an inserted rod in the rod holding member;
- and a detent member configured to selectively engage the at least one recess of the rod holding member to latch a pivot position of the rod holding member relative to the shaft, the method comprising:
- inserting a rod into the rod holding member while the rod holding member is in a first latched position;
- locking the rod in the rod holding member;
- disengaging the detent member from the rod holding member;
- pivoting the rod holding member until it is latched in a second latching position by the detent member, the second latching position being different from the first latching position;
- and
- unlocking the rod from the rod holding member.
