摘要

PROBLEM TO BE SOLVED: To provide a percutaneous intervertebral foramen extension treatment method according to intervertebral foramen ligament resection, and to provide a treatment tool used for the method.;SOLUTION: A percutaneous intervertebral foramen extension treatment method according to intervertebral foramen ligament resection comprises the steps of: examining a ligament on the periphery of an intervertebral foramen; determining a position through which a trocar is inserted according to the ligament structure; inserting the trocar toward a target point in an incision part through the skin of the intervertebral foramen adjacent part; inserting the trocar into a cannula, and then leaving the trocar to secure a space for inserting a subsequent tool; inserting an end mill into the cannula and making cuts in the ligament adhered to a vertebra intervertebral joint by rotating the end mill, and peeling off the ligament in the intervertebral foramen; leaving the end mill, then inserting a curette, peeling off ligament, with cuts, adhered to the vertebra intervertebral joint, scraping off the residues to extend the size of the intervertebral foramen; inserting a catheter into the intervertebral foramen, allowing a chemical agent to be transmitted to periphery nerve branches inducing pain, and discharging the chemical agent and the inflammatory substances inherent in the spinal canal and the intervertebral foramen.;COPYRIGHT: (C)2014,JPO&INPIT
