Implantable universal connector
One or more connectors insertable into a surgical incision to couple rods together. The connector may include one or more bushings or joints to displace the one or more rods in one or more directions to a variety of orientations. One or more fasteners and/or bushings may be used to engage the one or more rods.
1. An implantable connector system comprising:
a connector having a first receptacle, a second receptacle, and a first bushing received in the first receptacle, and wherein the connector includes a first threaded opening intersecting the first receptacle and a second threaded opening intersecting the second receptacle;
wherein the first receptacle includes a front opening connected to a back opening, a first axis of the first receptacle extending from a front side to a back side of the connector, wherein the front opening includes a continuous closed periphery defined entirely by the front side of the connector and the back opening includes a continuous closed periphery defined entirely by the back side of the connector, wherein the front opening is a slot for a first distance along the first axis of the first receptacle towards the back opening and intersects with an annular groove of the first receptacle formed within the continuous closed periphery defined by the front side of the connector and extending at least partially between and partially spaced from the front opening and the back opening, wherein the first bushing is axially loaded along the first axis through the slot of the first receptacle in a first orientation and when the bushing is positioned proximate the annular groove of the first receptacle the bushing is pivoted to a second orientation different from the first orientation;
a first rod matingly received within the first bushing when the first bushing is orientated in the second orientation;
a second rod matingly received within the second receptacle;
a first fastener configured to threadably engage the first threaded opening; and
a second fastener configured to threadably engage the second threaded opening.
2. The implantable connector system of claim 1 wherein the connector further includes a second bushing received within the second receptacle, and the second rod is matingly received within the second bushing.
3. The implantable connector system of claim 1 wherein the second receptacle includes a slot extending through an outer periphery of the connector to receive the second rod.
4. The implantable connector system of claim 1 wherein the first fastener and the second fastener are both a set screw.
5. The implantable connector system of claim 1 wherein the first receptacle of the connector includes a through hole and the first bushing includes an indentation, wherein the through hole of the first receptacle and the indentation of the first bushing receives a portion of a pin.
6. The implantable connector system of claim 1 wherein the first bushing is spherical and includes a slot.
7. The implantable connector system of claim 1 further comprising one or more pedicle screws.
8. The implantable connector of claim 1 wherein the first receptacle is slot shaped from the front opening to the back opening.
9. A connector for an implantable connector system, comprising:
a fixed body defining a first receptacle and a second receptacle;
the first receptacle, the second receptacle, or both having a bushing therein, wherein the bushing includes a first dimension along a longitudinal axis of a through opening therein and a second dimension perpendicular to the longitudinal axis, and wherein the first dimension is less than the second dimension;
a first threaded opening intersecting the first receptacle;
a second threaded opening intersecting the second receptacle;
a first fastener threadingly engaging the first threaded opening and extending into said first receptacle of the body;
a second fastener threadingly engaging the second threaded opening and extending into the second receptacle of the body; and
the first receptacle includes a front opening connected to a back opening of an outer periphery of the fixed body, wherein an axis extends between the front opening and the back opening, wherein at least the front opening is a slot, wherein the slot includes a continuous closed periphery defined only by a front side of the connector and the slot intersects with an annular groove of the first receptacle formed within the continuous closed periphery defined by the front side of the connector and extending at least partially between and partially spaced from the front opening and the back opening, wherein the closed periphery of the slot includes a length dimension and a width dimension perpendicular to and smaller than the length dimension, and wherein the width dimension of the slot is larger than the first dimension of the bushing and smaller than the second dimension of the bushing, wherein the bushing passes through the slot when in a first orientation when inserted into the first receptacle, wherein in the first orientation the width dimension of the slot is aligned with the first dimension of the bushing, and the bushing is pivoted to a second orientation different from the first orientation when assembled with the first receptacle of the fixed body.
10. The connector of claim 9 wherein each one of the first receptacle and the second receptacle includes the bushing.
11. The connector of claim 9 wherein the second receptacle includes a slot extending through an outer periphery of the connector to receive a second rod.
12. The connector of claim 11 wherein the slot passes through the second threaded opening.
13. The connector of claim 9 wherein the first receptacle of the connector includes a through hole and the bushing, wherein the bushing includes an indentation, and wherein the through hole of the first receptacle and the indentation of the bushing receives a portion of a pin.
14. The connector of claim 9 wherein the bushing allows displacement of a rod up to about 8 degrees about an axis of the first receptacle and/or the second receptacle, respectively.
15. A method of implanting an implantable connector system comprising the steps of:
providing a connector having a first receptacle, a second receptacle, and a first bushing positionable in the first receptacle, the first receptacle includes a front opening in a front side of the connector connected to a back opening in a back side of the connector, wherein an axis extends between the front opening and the back opening, wherein at least the front opening is a slot, wherein the slot includes a continuous closed periphery defined only by the front side of the connector and the slot intersects with an annular groove of the first receptacle formed within the continuous closed periphery defined by the front side of the connector and extending at least partially between and partially spaced from the front opening and the back opening;
axially loading the first bushing into the first receptacle along the axis in a first orientation;
pivoting the first bushing to a second orientation different from the first orientation after the first bushing in the first orientation is positioned in the first receptacle, and wherein the first orientation is perpendicular to the second orientation;
axially loading a first rod into the first bushing along the axis when the first bushing is in the second orientation;
inserting a second rod into the second receptacle;
threading a first fastener into a first threaded opening to engage the first bushing; and
threading a second fastener into a second threaded opening to engage the second receptacle.
16. The method claim 15 wherein the connector includes a second bushing in the second receptacle, and inserting the second rod into the second bushing in the second receptacle.
17. The method of claim 15 further comprising the step of at least one of loading the second rod into the second receptacle by at least axially-loading, top-loading, or side-loading.
18. The method of claim 15 further comprising the step of displacing the first rod and the first bushing up to about 8 degrees from an axis of the first receptacle.
