Methods and apparatuses for delivering a rod to a plurality of pedicle screws

摘要

Embodiments include a system that facilitates placement of a rod through receiving portions of screws placed along the spine. The system includes a rod and a cable detachably connectable to the rod to pull the rod through the receiving portions of the screws. Some embodiments include methods and devices for inserting a rod into a plurality of screws and for ex situ templating of a rod. These can include connecting a cable to a rod, inserting the cable through the plurality of screws, and using the cable to pull the rod into position. The methods of ex situ templating of the rod can include contacting a templating member to each of the screws so that a portion of the templating members replicate the relative positioning of the screws and shaping a rod to match the relative positioning of the portion of the templating members.

主权项

1. A system to facilitate placement of a rod through receiving portions of screws placed along the spine, comprising:
a rod; a pulling cable detachably connectable to the rod to pull the rod through the receiving portions of the screws, wherein the rod is connected to a first end of the cable; a penetrating member integral with or connectable with a second end of the pulling cable to direct the cable through the receiving portions of the screws, and one or more devices configured to control the advance and direction of advance of the penetrating member, the one or more devices comprising a first portion for penetration into a patient's body and a second portion comprising a handle with at least one operable control for at least one of selectively engaging the penetrating member and selectively advancing the penetrating member.
