Abstract
A sleeve system for lining a hole of a surgical screw in a bone or tissue of a subject includes a woven sleeve having a first end, a second end, and an elongated body. The elongated body has an interior portion. The first end includes an aperture that accesses the interior portion. The sleeve system also includes a protective tip that may be inserted through the aperture of the first end of the sleeve. The protective tip at least partially protects tissue of the subject from a screw positioned within the sleeve.
Core Innovation
The invention provides a sleeve system for lining a hole of a surgical screw in a bone or tissue of a subject. The sleeve system includes a woven sleeve having a first end, a second end, and an elongated body with an interior portion, and the first end has an aperture accessing the interior portion.
The invention further provides a protective tip or protective cap configured to be positioned in the second end of the woven sleeve within the bone via insertion through the aperture of the first end. The protective tip may be conical or frusto-conical and is configured to at least partially protect tissue of the subject from a screw positioned within the sleeve.
The invention also includes at least one additional woven sleeve configured to be inserted into the woven sleeve, and in another embodiment a plurality of woven sleeves configured to nest within each other when disposed within the bone or tissue. A protective cap is positioned in the second end of at least one of the plurality of sleeves to at least partially protect tissue from a screw positioned within at least one of the plurality of sleeves.
Claims Coverage
The partial content identifies two independent claims. Each independent claim centers on a woven sleeve system with a first-end aperture and a second-end protective element, with claim-specific distinctions in how protective elements are used and how multiple sleeves are nested or inserted. Across the independent claims, three main inventive features appear.
Aperture-accessible first-end woven sleeve lining a surgical screw hole
A sleeve system for lining a hole of a surgical screw in a bone or tissue, including a woven sleeve having a first end, a second end, and an elongated body with an interior portion, where the first end has an aperture accessing the interior portion.
Protective tip positioned in the sleeve second end via aperture insertion
A protective tip configured to be positioned in the second end of the woven sleeve within the bone via insertion through the aperture of the first end of the woven sleeve or the at least one additional woven sleeve.
Additional woven sleeve inserted into the woven sleeve
At least one additional woven sleeve configured to be inserted into the woven sleeve when the woven sleeve is positioned within the bone or tissue of the subject.
Nested plurality of woven sleeves
A sleeve system for lining a hole of a surgical screw in a bone or tissue, comprising a plurality of woven sleeves, each having a first end, a second end, and an elongated body with an interior portion, where the first end has an aperture accessing the interior portion, and wherein the plurality of woven sleeves are configured to nest within each other when disposed within the bone or tissue.
Protective cap positioned in the nested woven sleeve second end for tissue protection
A protective cap configured for positioning in the second end of at least one of the plurality of woven sleeves, wherein the protective cap is configured to at least partially protect tissue of the subject from a screw positioned within at least one of the plurality of sleeves.
Overall, the independent claims cover sleeve systems that line a surgical screw hole using a woven sleeve with a first-end aperture, in combination with a protective element positioned in the second end to protect tissue from a screw. One independent claim emphasizes a protective tip inserted through the first-end aperture and allows insertion of at least one additional woven sleeve, while the other independent claim emphasizes a nested plurality of woven sleeves and a protective cap positioned in the second end of one or more of the nested sleeves.
Stated Advantages
Protects tissue of the subject from a screw positioned within the sleeve(s).
Protective tip is configured to protect tissue from a screw positioned within the sleeve.
Documented Applications
Lining a hole of a surgical screw in a bone or tissue of a subject, including use with pedicle screws in a surgical screw hole.
