Abstract:
1. An instrument guide, comprising: a releasable lock assembly comprising a movable outer tubular member having a lumen, the outer tubular member being movable in the longitudinal direction between a distal configuration and a proximal configuration; a shaft having a proximal end and a distal end, wherein the shaft is partially in the lumen of the releasable lock assembly; a handle at the proximal end of the shaft; a device coupler comprising a coupling base with a through lumen and an elongate coupling member comprising a proximal end and a distal end, wherein the distal end is configured with a least one mechanical interfit structure, wherein at least a portion of the elongate coupling member is configured so as to move in the through lumen of the coupling base; and at least one drill guide member joined to the device coupler; wherein the releasable lock assembly is configured to releasably lock the proximal end of the elongate coupling member of the device coupler to the distal end of the shaft when the outer tubular member is in a distal configuration.
