Abstract
A portal for use in a spinal implantation procedure is disclosed herein. The portal includes base and first and second paddles pivotally coupled to the base. The paddles can be pivoted between a distraction orientation and an insertion orientation. In the insertion orientation, the paddles are adapted for insertion between vertebrae that are in need of distraction. In the distraction orientation, the paddles are adapted to hold the vertebrae spaced apart at a distracted spacing. In the distraction orientation, the portal defines a portal window for accessing the disc space between the two distracted vertebrae.
Claims27
A portal for use in a spinal implantation procedure comprising:
- a base;
- a first paddle that is pivotally coupled to the base;
- and
- a second paddle that is pivotally coupled to the base, wherein the first paddle and the second paddle are dimensioned to fit in a disc space between two adjacent vertebrae of a spine of a patient.
A portal for use in distracting adjacent vertebrae, the portal comprising:
- first and second paddles, the paddles having heights sized to correspond to a desired distraction spacing between the adjacent vertebrae, and thicknesses sized to permit insertion of the paddles between the vertebrae prior to distraction of the adjacent vertebrae;
- and
- a bridge member that spans a distance between the first and second paddles, the first and second paddles being moveable relative to the bridge between a closed position and an open position, wherein the paddles are adapted for insertion between the adjacent vertebrae prior to distraction when in the closed position, and the paddles are adapted to maintain the desired distraction spacing between the adjacent vertebrae when in the open position.
A portal for use in a spinal implantation procedure comprising:
- a base having a length between a first end and an opposite second end;
- a first paddle sized to fit in a disc space between two vertebrae, the first paddles having a first edge, a second edge, and a third edge, and a fourth edge, wherein the first edge is approximately parallel to the second edge, the third edge is approximately parallel to the fourth edge, and the first edge is approximately perpendicular to the third edge, wherein the first paddle has a width between the third edge and the fourth edge, and a length between the first edge and the second edge, wherein the first paddle is pivotally coupled to the first end of the base and is pivotally movable between a first position and a second position, and wherein the first paddle is approximately parallel to the base when the first paddle is in the first position, and the first paddle is approximately perpendicular to the base when the first paddle is in the second position;
- a second paddle sized to fit in the disc space between two vertebrae, the second paddle having a first edge, a second edge, a third edge, and a fourth edge, wherein the first edge of the second paddle is approximately parallel to the second edge of the second paddle, the third edge of the second paddle is approximately parallel to the fourth edge of the second paddle, and the first edge of the second paddle is approximately perpendicular to the third edge of the second paddle, wherein the second paddle has a width between the third edge and the fourth edge, and a length between the first edge and the second edge, wherein the second paddle is pivotally coupled to the second end of the base, and the second paddle is pivotally movable between a first position and a second position, wherein the second paddle is approximately parallel to the base when the second paddle is in the first position, and the second paddle is approximately perpendicular to the base when the second paddle is in the second position.
A spinal distractor system comprising:
- a flip-up portal comprising a base, a first paddle, and a second paddle, the first paddle and the second paddle being movable between open and closed positions, the first and second paddles being approximately parallel to the base when in the closed position and the first and second paddles being approximately perpendicular to the base when in the open position;
- and
- an actuator for insertion of the flip-up portal into a disc region between two vertebrae, the actuator including at least one handle that is rotated to move the first and second paddles from the closed position to the open position.
A method of distraction of a disc space between adjacent vertebrae of a spine of a patient for a surgical procedure, comprising:
- inserting a flip-up portal into the disc space while the portal is in an insertion orientation;
- and
- expanding the portal to a distraction orientation in which the portal separates the vertebrae and provides a portal window for accessing the disc space.
