Abstract: Methods and instruments for placement of orthopedic implants in bones of a patient. The placement may include selective placement of the implant relative to structure of the bone using a measurement system that may detect interfaces between layers of the bone. The orthopedic implants may be engaged by various embodiments of chucks. The chucks may include structure for engaging indexing features of a corresponding orthopedic implant to restrict movement of the implant relative to the chuck along a working axis. The chucks may allow for use of an instrument having a measurement system for accurate and repeatable placement of the implants using the instrument.

Abstract: Systems for variable angle insertion of surgical fasteners relative to an orthopedic plate with locking of the surgical fastener relative to the plate upon insertion. The systems may include a pivot member secured relative to either the orthopedic plate or the fastener. In either regard, the pivot member may provide locking engagement with the plate to lockingly engage the fastener relative to the plate.

Abstract: An implant driver for engaging an orthopedic implant for selective advancement and retraction of the implant. The implant driver includes a first jaw assembly comprising a helical cam surface corresponding with a first direction of rotation. The first jaw assembly is operative to engage, in response to rotation in the first direction, the implant using spherical jaw members disposed in constrictive helical channels. The implant driver includes a second jaw assembly comprising a helical cam surface corresponding with a second direction of rotation. The second jaw assembly is operative to engage, in response to rotation in the second direction, the implant using spherical jaw members disposed in constrictive helical channels. Absent rotation of the first and second jaw assemblies, the spherical jaws may not restrict relative axial movement between the implant and the implant driver to allow for advancement and/or retraction of the instrument relative to the implant.

Abstract: Drill bit guide assemblies related to surgical operations for guiding and stabilizing a drill bit. A guide member houses a fixed bore through which a drill bit may pass. The guide member may also house a bore selection member which houses a plurality of selectable bores. The selectable bores may have a variety of diameters such that a user may choose the selectable bore corresponding to the drill bit diameter being used and align that selectable bore with the fixed bore such that the drill bit may pass through the length of the assembly along the reference axis. The similar diameters of the selectable bore and the drill bit may cause the assembly to stabilize and guide the drill bit.

Abstract: A resin insertion device includes a barrel, a piston within the barrel, and a triggering mechanism. The triggering mechanism includes an air outlet, an air inlet, a venturi tube and at least one trigger piston. A resin insertion device includes a barrel having a collar disposed at a first end and a piston disposed slidably within the barrel. A triggering mechanism is disposed at a second end. A first position of the trigger prevents airflow through an air inlet, a second position allows air through the inlet and an outlet, and a third position prevents airflow through the outlet. A method of inserting resin into a bore hole includes providing an insertion device including a barrel, and a triggering mechanism. The method includes depressing a trigger from a first to a second position, placing at least one resin cartridge within the barrel, and further depressing the trigger.
