Abstract
Abstract An implant insertion apparatus for guiding surgical instrumentation and facilitating insertion of surgical implants into an intervertebral space, including a retractor having an internal opening for introduction of a surgical instrument and positionable with respect to adjacent vertebrae in the intervertebral space, and a guide bar mounted to the retractor. The guide bar includes a longitudinal guide shaft dimensioned to guide introduction of surgical instrumentation through the internal opening of the retractor. The apparatus further includes a guide member mounted to the surgical instrument for providing the guidance thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
157 words
A system for facilitating insertion of an implant into an intervertebral space, which comprises: a retractor including an insertion end portion and a trailing end portion, the insertion end portion configured to at least partially span the intervertebral space defined between adjacent vertebrae to maintain the adjacent vertebrae in a predetermined spaced relation, the retractor defining an internal passage to permit introduction of a surgical instrument therethrough; and a guide for guiding the surgical instrument through the internal passage of the retractor, the guide including a guide shaft connectable to the retractor and defining a longitudinal axis and a guide attachment mounted to the guide shaft, the guide attachment adapted for reciprocal longitudinal movement relative to the guide shaft and having mounting structure configured for releasably engaging the surgical instrument such that the surgical instrument is guided along the guide shaft upon longitudinal movement of the guide attachment for reception within the internal passage of the retractor.
Claim 2
Independent Claim
157 words
A system for facilitating insertion of an implant into an intervertebral space, which comprises: a retractor including an insertion end portion and a trailing end portion, the insertion end portion configured to at least partially span the intervertebral space defined between adjacent vertebrae to maintain the adjacent vertebrae in a predetermined spaced relation, the retractor defining an internal passage to permit introduction of a surgical instrument therethrough; and a guide for guiding the surgical instrument through the internal passage of the retractor, the guide including a guide shaft connectable to the retractor and defining a longitudinal axis and a guide attachment mounted to the guide shaft, the guide attachment adapted for reciprocal longitudinal movement relative to the guide shaft and having mounting structure configured for releasably engaging the surgical instrument such that the surgical instrument is guided along the guide shaft upon longitudinal movement of the guide attachment for reception within the internal passage of the retractor.
Claim 3
Dependent Claim
23 words
The system according to claim 1 wherein the guide attachment includes a base defining a longitudinal opening therethrough for receiving the surgical instrument.
Claim 4
Dependent Claim
27 words
The system according to claim 2 wherein the base of the guide attachment is configured and dimensioned to receive a surgical drill within the longitudinal opening thereof.
Claim 5
Dependent Claim
28 words
The system according to claim 2 wherein the base of the guide attachment is configured and dimensioned to receive an implant insertion instrument within the longitudinal opening thereof.
Claim 6
Dependent Claim
31 words
The system according to claim 2 wherein the guide shaft and the guide attachment include corresponding longitudinal guide structure to permit sliding movement along the longitudinal axis without rotational movement there-between.
Claim 7
Dependent Claim
16 words
The system according to claim 1 wherein the guide shaft is releasably connected to the retractor.
Claim 8
Dependent Claim
52 words
The system according to claim 1 wherein the retractor includes at least one distractor arm having first and second opposed supporting surfaces for engaging respective opposed vertebrae, the one distractor arm defining a dimension between the first and second supporting surfaces sufficient to maintain the adjacent vertebrae in the predetermined spaced relation.
Claim 9
Dependent Claim
26 words
The system according to claim 1 wherein the guide shaft includes a depth indicator for indicating insertion depth of the surgical instrument into the intervertebral space.
Claim 10
Independent Claim
129 words
A method for performing a surgical procedure comprising the steps of: introducing a retractor into an intervertebral space defined between adjacent vertebra to maintain the adjacent vertebrae in predetermined space relation, the retractor defining an internal lumen for passage of a surgical instrument and having a longitudinal guide bar releasably connected to the retractor; mounting a guide attachment to the guide bar, the guide attachment supporting a surgical instrument; advancing the surgical instrument along the guide bar whereby the guide bar guides the surgical instrument through the internal lumen of the retractor and adjacent the intevertebral space, wherein the step of advancing includes sliding the guide attachment along the guide bar whereby the surgical instrument moves with the guide attachment adjacent the intevertebral space; and performing a surgical procedure.
Claim 11
Independent Claim
129 words
A method for performing a surgical procedure comprising the steps of: introducing a retractor into an intervertebral space defined between adjacent vertebra to maintain the adjacent vertebrae in predetermined space relation, the retractor defining an internal lumen for passage of a surgical instrument and having a longitudinal guide bar releasably connected to the retractor; mounting a guide attachment to the guide bar, the guide attachment supporting a surgical instrument; advancing the surgical instrument along the guide bar whereby the guide bar guides the surgical instrument through the internal lumen of the retractor and adjacent the intevertebral space, wherein the step of advancing includes sliding the guide attachment along the guide bar whereby the surgical instrument moves with the guide attachment adjacent the intevertebral space; and performing a surgical procedure.
Claim 12
Dependent Claim
27 words
The method according to claim 9 wherein the surgical instrument is a surgical drill, and the step of performing includes drilling a bore within the intervertebral space.
Claim 13
Dependent Claim
22 words
The method according to claim 10 wherein the step of performing includes introducing an implant within the bore of the intervertebral space.
Claim 14
Dependent Claim
38 words
The method according to claim 11 wherein the surgical instrument is an implant insertion instrument to which the implant is releasably mounted and wherein the step of introducing the implant includes releasing the implant from the insertion instrument.
Claim 15
Dependent Claim
18 words
The method according to claim 9 further including the step of connecting the guide bar to the retractor.
