Paragraph Number

145

In one embodiment, a user can rotate the guide 802 about the engagement axis 412 until a desired orientation of the guide 802 in relation to the fastener 804 is found. Once the desired orientation is found or obtained, the guide 802 can be secured to maintain the desired orientation. In one embodiment, to secure the guide 802 a user may engage a lock mechanism 824. Referring to FIG. 47, to engage the lock mechanism 824 a user may press the handle 826 toward the inserter 806. In the illustrated embodiment, the inserter 806 includes a threaded socket 880. A user may rotate the shaft 828 by turning the handle 826 about the engagement axis 412 in a direction that causes the shaft 828 to advance distally within the socket 880. For example, threads 834 of the shaft 828 may engage internal threads 886 of the socket 880. As the shaft 828 is rotated the shaft 828 may advance distally into the socket 880. As the shaft 828 advances, the shoulder 830 of the lock mechanism 824 pinches the guide body 814 against the inserter 806. In one embodiment, this contact provides sufficient friction to retain the guide 802 in the desired orientation. In certain embodiments, the user may tighten the lock mechanism 824 to increase the resistance to rotation by guide 802 about the engagement axis 412.
