Abstract
An adjustable trial spacer system used in spinal surgeries. This system addresses the inefficiencies of traditional trial sizers by introducing a trial base that can be combined with disposable trial caps of varying sizes. The trial base is designed to securely attach to a trial inserter, while the trial caps temporarily enclose the trial base to simulate the final implant. The system's modularity reduces the need for multiple spacer bodies, lowers costs, and improves logistical management in the operating room. Various attachment mechanisms ensure secure fitting during surgical procedures, enhancing precision in determining the appropriate implant size.
Claims16
An adjustable trial spacer system, comprising:
- a trial base having a predetermined thickness, wherein the trial base includes an attachment feature configured to engage a trial inserter;
- a plurality of trial caps, each trial cap including:
- a predetermined thickness that is greater than the predetermined thickness of the trial base and distinct from other trial caps;
- a first section and a second section, the first section and the second section configured to temporarily connect to each other and house at least a portion of the trial base, and the first section and the second section further configured to detach from each other;
- and
- one or more interlocking components to securely attach the first section to the second section, wherein the one or more interlocking components include an extension projecting inwardly from the first section, and a receipt extending inwardly from the second section, the receipt configured to engage the extension when the first section and the second section are attached, and the trial base including a retention aperture configured to enable passage of the extension therethrough.
An adjustable trial spacer system, comprising:
- a trial inserter having an elongated shaft;
- a trial base having a predetermined thickness, wherein the trial base includes an attachment feature configured to engage the trial inserter;
- a plurality of trial caps, each trial cap including:
- a first section and a second section, wherein the first section and the second section are configured to sandwich the trial base;
- a predetermined thickness when sandwiching the trial base that is greater than the predetermined thickness of the trial base and distinct from other trial caps;
- and
- one or more interlocking components to securely attach the first section to the second section, wherein the one or more interlocking components include an extension projecting inwardly from the first section, and a receipt extending inwardly from the second section, the receipt configured to engage the extension when the first section and the second section are attached, and the trial base including a retention aperture configured to enable passage of the extension therethrough.

- a plurality of trial caps, each trial cap including:
- a predetermined thickness that is greater than the predetermined thickness of the trial base and distinct from other trial caps;
- a first section and a second section, wherein the first section and the second section are configured to temporarily house at least a portion of the trial base;
- and
- one or more interlocking components to securely attach the first section to the second section and retain the trial base between the first section and the second section, wherein the one or more interlocking components include an extension projecting inwardly from the first section, and a receipt extending inwardly from the second section, the receipt configured to engage the extension when the first section and the second section are attached, and the trial base including a retention aperture configured to enable passage of the extension therethrough.
