Abstract
A surgical instrument includes a first member defining a passageway. The first member includes a first lock and a second lock. A second member is positioned in the passageway. A third member is coupled to the second member. The second member is movable relative to the first member to move the third member between a first position in which the first lock is spaced a first distance apart from the second lock, and a second position in which the first lock is spaced a reduced second distance apart from the second lock. Systems, spinal implants and methods are disclosed.
Claims20
A surgical instrument comprising:
- a first member defining a passageway, the first member comprising a first lock and a second lock;
- a second member positioned in the passageway, the second member comprising a lumen and a spring tab;
- a third member coupled to the second member;
- and
- a fourth member positioned in the lumen of the second member, the fourth member being movable relative to the second member between a first orientation in which the fourth member prevents the spring tab from deflecting inwardly and a second orientation in which the spring tab is allowed to deflect inwardly,
- wherein the second member is coupled to the third member and movable relative to the first member to move the third member between a first position in which the first lock is spaced a first distance apart from the second lock, and a second position in which the first lock is spaced a second distance apart from the second lock, the second distance being less than the first distance.
A surgical instrument comprising:
- an inserter body comprising a shaft defining a passageway, the shaft comprising a first spring tab and a second spring tab;
- a pusher positioned in the passageway;
- and
- a sleeve coupled to the pusher,
- wherein the pusher is movable relative to the inserter body to move the sleeve between a first position in which the first spring tab is spaced a first distance apart from the second spring tab, and a second position in which the first spring tab is spaced a reduced second distance apart from the second spring tab.
A surgical system comprising:
- a surgical instrument comprising:
- a first member defining a passageway, the first member comprising a first lock and a second lock,
- a second member positioned in the passageway, the second member comprising a lumen and a spring tab,
- a third member coupled to the second member, and
- a fourth member positioned in the lumen of the second member, the fourth member being movable relative to the second member between a first orientation in which the fourth member prevents the spring tab from deflecting inwardly and a second orientation in which the spring tab is allowed to deflect inwardly;
- and
- an implant comprising a head,
- wherein the second member is movable relative to the first member to move the third member between a first position in which the first lock is spaced a first distance apart from the second lock to allow the head to be inserted into the passageway, and a second position in which the lock is spaced a reduced second distance apart from the second lock such that the locks engage the head within the passageway to fix the head relative to the shaft.
