Apparatus for Reinforcing Bone and Tools for Mounting the Same

摘要

An apparatus, for reinforcing bone and tools for mounting the same, has an implant including a barrel and a device. The implant can be expanded by an expanding apparatus including an outer tube, a base, a hollow body and a handle. The expanding apparatus can be bound to the implant to place the implant into a bone to be treated and adjust the expansion degree. The expanding apparatus can be replaced by an injector apparatus including a container for bone cement and an injecting handle. The injector apparatus can inject a mixture for reinforcing bone (e.g., bone cement) into the bone through an exit, the device, the aperture, the barrel and the window of the barrel, and into the to-be treated area.

主权项

1. An apparatus for reinforcing a damaged bone, comprising:
a cap having a through hole; a substantially rigid tube having the cap at one end thereof, with a lumen extending through the cap and the substantially rigid tube and being open at both ends, wherein the substantially rigid tube comprises:
a tapered end on an outer wall of the substantially rigid tube and distal to the cap, with the tapered end tapering to a smaller size away from the cap;an aperture extending from the outer wall and proximal to the cap and allowing materials to pass into and out of the substantially rigid tube; anda threaded inner wall in the lumen which allows the apparatus to be securely handled, wherein the inner threaded wall is proximal to the tapered end; and a barrel encasing the substantially rigid tube, wherein the barrel comprises an adjustable part and a securing part movable on the outer wall toward the cap in response to an external force and to be fixed at a desired position on the outer wall proximal to the tapered end of the substantially rigid tube, with the adjustable part sandwiched and having a length between the cap and the securing part, and wherein the securing part transfers the external force to the adjustable part in order to reduce the length and to expand the adjustable part from a first geometry to a second geometry.
