发明名称 Minimally invasive tool to facilitate implanting a pedicle screw and housing
摘要 A minimally invasive tool to facilitate implanting a pedicle screw and housing is provided. The minimally invasive tool includes a first sleeve having flexible tabs that couple to a housing and a second sleeve slidably engaged in the first sleeve. The second sleeve provides reinforcing such that the first and second sleeve provide counter torque for driving the pedicle screw.

主权项 1. A method of attaching a tool to an implant to facilitate minimally invasive surgical procedures, the method comprising the steps of: providing a tool comprising an inner sleeve having first and second elongate portions, each of the first and second elongate portions having a distal end and a proximal end, the inner sleeve having first and second slots extending between the first and second elongate portions from the distal ends thereof, the first and second slots each having a slot length greater than one half of a length of the first and second elongate portions; an outer sleeve comprising third and fourth elongate portions, each of the third and fourth elongate portions having distal and proximal ends, the outer sleeve member further comprising third and fourth slots extending between the third and fourth elongate portions from the distal ends thereof, the third and fourth slots each having a length greater than one half the length of the third and fourth elongate portions, wherein the inner sleeve is sized to be received within the outer sleeve, a connector member adapted to couple the proximal ends of the first and second elongate portions with the proximal ends of the third and fourth elongate portions, respectively; an alignment feature adapted to align the first slot with the third slot, and to align the second slot with the fourth slot, when the inner sleeve is received within the outer sleeve, wherein the alignment feature comprises at least one alignment channel located at the distal end of one of the first and second elongate portions, and at least one alignment projection located on a radial inner surface proximate the distal end of one of the third and fourth elongate portions and configured to selectively lock with the at least one alignment channel; and an implant engagement feature disposed on a distal end of the third elongate member, the implant engagement feature adapted to releasably secure the second sleeve to the implant; inserting the distal ends of the third and fourth elongate portions through an incision until the distal ends are proximate the implant; coupling the distal ends of the third and fourth elongate portions to the implant using the implant engagement feature; sliding the inner sleeve inside the outer sleeve such that the first and second elongate portions move along the third and fourth elongate portions until a first alignment portion disposed on the distal end of at least one of the first and second elongate portions engages a second alignment portion disposed on an uppermost edge of the implant; and moving a part of the implant along the slot and between the first and second elongate portions until the part of the implant is implanted at a surgical site.
