Benefits of technology

The present invention provides a method for performing a percutaneous extraforaminotomy with foraminal ligament resection that can effectively treat pain by using chemical materials. The method includes using instrument tools that include a trocar, cannula, endmill, and curret to precisely resect the target ligament and remove blockages from the intervertebral foramen. The instrument tools help to smoothly discharge inflammatory materials existing in the spinal canal and reduce pain. The technical effects of this invention are improved pain treatment and the use of safe and effective instrument tools for the procedure.

Problems solved by technology

However, the study and analysis regarding the clinical significance of this is presently not sufficient.
That is, most of neurosurgeons have believed that mechanical problems such as disc herniation and spinal stenosis cause sciatica, much more back pain.

Abstract

Provided is an instrument tool for performing a percutaneous extraforaminotomy with foraminal ligament resection, which examines various ligaments around intervertebral foramen, artificially expands the intervertebral foramen blocked by adhesive fibrosis through repeated inflammatory reactions using epidural neurolysis or percutaneous extraforaminotomy, transmits chemical materials efficacious in pain treatment to the periphery of nervous branches causing pain through a catheter, and smoothly discharges an inflammatory material existing in spinal canal with the chemical materials through the intervertebral foramen.

Description

CROSS-REFERENCE(S) TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 13 / 768,848 filed on Feb. 15, 2013, which claims priority of Korean patent application number 10-2012-0143335 filed on Dec. 11, 2012. The disclosure of each of the foregoing applications is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to instrument tools for performing a percutaneous extraforaminotomy with foraminal ligament resection, which is capable of relieving pain by discharging an inflammatory material existing in spinal canal through intervertebral foramen to the outside, and instrument tools used for the same, and more particularly, to a percutaneous extraforaminotomy with foraminal ligament resection, which expands the size of intervertebral foramen by resecting minute ligaments entangled in the intervertebral foramen through instrument tools such that a chemical material supplied to spinal ...
