Abstract
A surgical instrument comprises a first member defining a cavity configured for disposal of a plurality of implants and including a distal portion that retains the implants with the first member. An element is configured to urge the implants in a first, release direction and the first member having at least one tab movable to prevent movement of at least one of the implants in a second direction. A second member is engageable with the at least one tab. Systems, spinal implants and methods are disclosed.
Claims20
A surgical instrument comprising:
- a first member extending along a longitudinal axis between a proximal end and an opposite distal end, the first member including a wall defining a cavity extending along the longitudinal axis and configured for disposal of a bone fastener receiver, the first member including a collet within the cavity, the collet retaining the receiver with the first member, the first member including a piston engageable with the receiver in a first, release, direction along the longitudinal axis, the wall defining a tab;
- a second member movable relative to the first member between a first position and a second position such that the second member engages the tab in the second position to prevent movement of the receiver in an opposite second direction along the longitudinal axis;
- and
- an actuator including a handle and a spring, an end of the second member being positioned within the handle such that the spring is positioned about the second member to bias the second member to the second position,
- wherein the second member includes an outer sleeve and the first member includes an inner sleeve disposed within the outer sleeve.
A surgical instrument comprising:
- a first member extending along a longitudinal axis between a proximal end and an opposite distal end, the first member including a wall defining a cavity extending along the longitudinal axis and configured for disposal of a plurality of bone fastener receivers, the first member including a an expandable collet positioned within the cavity that retains the receivers with the first member, the receivers being disposed in a stacked orientation within the cavity, the first member including a piston engageable with the receivers in a first, release, direction along the longitudinal axis, the wall defining a pair of spring biased tabs;
- a second member movable relative to the first member between a proximal position and a distal position such that the second member engages the tabs in the distal position to prevent movement of the receivers in an opposite second direction along the longitudinal axis;
- and
- an actuator including a handle and a spring, an end of the second member being positioned within the handle such that the spring is positioned about the second member to bias the second member toward the distal position.
A surgical instrument comprising:
- an inner tubular sleeve extending along a longitudinal axis between a proximal end and an opposite distal end, the inner sleeve including a wall defining a cavity extending along the longitudinal axis and configured for disposal of a plurality of bone fastener receivers, the inner sleeve including an expandable collet within the cavity, the inner sleeve further including a piston engageable with the receivers in a first, release, direction along the longitudinal axis, the wall defining at least one tab;
- an outer tubular sleeve movable relative to the inner sleeve between a proximal position and a distal position such that the outer sleeve engages the at least one tab in the distal position to prevent movement of at least one receiver in an opposite second direction along the longitudinal axis;
- and
- an actuator including a handle and a spring, an end of the outer sleeve being positioned within the handle such that the spring is positioned about the outer sleeve to bias the outer sleeve toward the distal position.
