摘要：
Devices, systems, and methods for locking a drill guide into a polyaxial hole while maintaining the form and function of the polyaxial hole are provided herein. In some embodiments, the drill guide includes a hollow outer body extending from a proximal end to a distal end and having a slot disposed proximate the proximate end, wherein the distal end is configured as a reverse collet having a plurality of prongs； an inner body having a central channel extending therethrough； and a lever coupled to the inner body through the slot, wherein the slot is shaped such that rotation of the lever results in motion along a central axis of the drill guide, and wherein a distal end of the inner body is configured to prevent radially inward deflection of the plurality of prongs when the inner body is in a lowermost position.
