US 11,628,004 B2 · Surgical fastener manipulation tool

Abstract

A surgical fastener manipulation tool in accordance with embodiment of the present invention is useful by a surgeon to place fasteners such as threaded screws. The surgical fastener manipulation tool selectively engages a mating structure of fastener for securing the fastener thereto. Thus, advantageously, the surgical fastener manipulation tool can be used for placing such fasteners and/or can be used for extracting (i.e., removing) such fasteners. The ability to extract a fastener (e.g., a threaded bone screw) with the same tool used for placing it is highly beneficial due to time savings during a surgical procedure and is advantageous with respect to prior art fastener manipulation tool configurations that require placement and extraction tools to be differently configured.

Dependent claims

A tool for use with a fastener having one or more tool lock recesses within side walls of a tool interface structure that is within a head portion thereof, comprising:

a fastener engagement structure that is matingly engageable within the tool interface structure of the fastener;
and
a lock member adjacent to the fastener engagement structure, wherein the lock member includes an engagement portion thereof that is selectively engageable within at least one of the tool lock recesses of the tool interface structure through rotation of the lock member relative to the fastener engagement structure, wherein the lock member is rotatable between an unlock position in which a sidewall profile of the lock member is aligned with a respective portion of a sidewall profile of the fastener engagement structure and a lock position in which at least a portion of the sidewall profile of the lock member is misaligned with at least a portion of the sidewall profile of the fastener engagement structure thereby enabling selective alignment and misalignment of the sidewall profile of the lock member and the sidewall profile of the fastener engagement structure and wherein at least a portion of the lock member becomes engaged with one or more of the tool lock recesses when the lock member is rotated from the unlock position to the lock position.

A tool for use with a fastener having one or more tool lock recesses within side walls of a tool interface structure that is within a head portion thereof, comprising:

a fastener engagement structure that is matingly engageable within the tool interface structure of the fastener;
and
a lock member rotatably attached to the fastener engagement structure, wherein the lock member is located adjacent to the fastener engagement structure and wherein the lock member includes an engagement portion thereof that is selectively engageable within at least one of the tool lock recesses of the tool interface structure through rotation of the lock member relative to the fastener engagement structure for enabling the fastener to be releasably secured to the fastener engagement structure, wherein the lock member and the fastener engagement structure each have a common sidewall profile, wherein the lock member has a plurality of fastener engagement portions defining a sidewall profile thereof, wherein the sidewall profile of the lock member is aligned with a sidewall profile of the fastener engagement structure when the lock member is in an unlock position and wherein the sidewall of the lock member is misaligned with the sidewall profile of the fastener engagement structure when the lock member is in a lock position.

A tool for use with a fastener having a tool interface structure, comprising:

a housing having a fastener engagement structure, wherein the fastener engagement structure has an exterior surface that is matingly engageable within the tool interface structure of the fastener;
and
a lock member abutting an end face of the fastener engagement structure, wherein at least a portion of the lock member is movable relative to the fastener engagement structure for being engaged with a lock member receiving portion of the tool interface structure and is movable relative to the fastener engagement structure for being disengaged from the lock member receiving portion of the tool interface structure.
