Abstract
Surgical instrumentation may be used to insert a spinal implant into an intradiscal space while in a non-deployed condition and then deploy the spinal implant within the intradiscal space.
Claims14
Surgical instrumentation for use with an associated intradiscal space comprising a first vertebral body having a first endplate and a second vertebral body adjacent the first vertebral body having a second endplate, the surgical instrumentation comprising:
- an implant comprising:
- 1) a first portion;
- 2) a second portion that is pivotal with respect to the first portion;
- 3) wherein the first and second portions define first and second contact surfaces adapted to contact the first and second endplates, respectively;
- and
- 4) wherein the implant is deployable by pivoting the second portion with respect to the first portion;
- an inserter adapted to insert the implant into the associated intradiscal space when not deployed and to deploy the implant within the associated intradiscal space, the inserter comprising:
- 1) a handle;
- 2) a sheath including:
- (a) a proximal end supported to the handle;
- (b) a distal end, opposite the proximal end;
- (c) a longitudinally extending channel that extends from the proximal end to the distal end and gives the sheath a tube shape;
- and
- (d) a groove formed at the distal end that communicates with the longitudinally extending channel;
- 3) a gripping device including:
- (a) a proximal end supported to the handle;
- (b) a distal end, opposite the proximal end, adapted to grip and release the first portion of the implant;
- (c) a longitudinally extending channel that extends from the proximal end to the distal end and gives the gripping device a tube shape;
- (d) a groove formed at the distal end that communicates with the longitudinally extending channel;
- and
- (e) wherein the gripping device is positioned within the longitudinally extending channel of the sheath;
- 4) a pusher including:
- (a) a proximal end supported to the handle;
- (b) a distal end, opposite the proximal end;
- (c) an implant engagement finger supported to the distal end;
- (d) wherein the pusher is positioned within the longitudinally extending channel of the gripping device;
- and
- (e) wherein the implant engagement finger includes:
- (i) a first portion that extends through the groove in the gripping device and into the groove in the sheath;
- and
- (ii) a second portion that extends along the groove in the sheath and is adapted to contact the implant;
- wherein:
- 1) the sheath is:
- (a) operable to be moved distally to cause the gripping device to grip the first portion of the implant;
- and
- (b) operable to be moved proximally to cause the gripping device to release the first portion of the implant;
- and
- 2) the pusher is:
- (a) operable to be moved proximally away from the implant;
- and
- (b) operable to be moved distally to cause the implant engagement finger to engage the second portion of the implant to deploy the implant when the gripping device grips the first portion of the implant.
