Disclosed are reducer instrument locking mechanisms. They can be located near a center pivot joint of the reducer, thereby eliminating a ratchet at the reducer proximal end. The locking mechanisms can include a pawl or latch that travels with one handle from an open position to a closed position. The pawl can fall into a groove formed in an opposing handle such that handles of the reducer can be locked relative to one another, at least with regard to movement of the handles away from one another. When falling into the groove, the pawl can create an auditory and/or tactile indication that a sufficient amount of rod reduction has been achieved to allow for set screw insertion. After set screw insertion, the reducer locking mechanisms can be released to clear it of the groove and allow the reducer to return to its open position.

Reducer locking mechanisms and methods of use

An array stabilizer for a surgical system includes a pair of arms configured to extend alongside opposite sides of a portion of an array adapter, which is attachable to a rotational instrument in a manner such that the rotational instrument is rotatable about a central axis relative to the array adapter. The array adapter is configured to extend from another component of the surgical system, such that at least one of the arms of the array adapter is configured to resist rotation of the array adapter about the central axis relative to such component as the rotational instrument rotates. The array stabilizer is either rigidly integrated with such component or is coupled to such component via a coupling device.

Surgical array stabilizers, and related systems and methods

Systems, methods, and devices are disclosed for robotic surgical systems including a robotic arm, the systems comprising an end effector attached to the robotic arm and retaining an access guide, and an initial access tool detachably connected to the access guide, wherein the initial access tool comprises a housing, a shaft extending from the housing coaxially through the access guide, and a distal tip attached to the shaft and protruding from a portion of the access guide distal to the end effector, wherein the housing is adapted to prevent rotation with respect to the access guide. In some embodiments, the access guide is adapted to retain an initial access tool and one or more of a burring tool, a drilling tool, or a tapping tool. In some embodiments, the initial access tool further comprises a step spaced from a distal end of the shaft, a rigid sleeve for placing over the shaft below the step, a spring for placing over the shaft below the step, and at least one detachable tip for engaging the distal end of the shaft, wherein the housing is adapted to prevent rotation with respect to the access guide.
