Seriously damaged leg due to a product called, Orbitrim Weed eater. Do I have a Defective Product Case?

Attached product to my Troy Bilt Weed Eater. During the 3rd usage, the product broke lose from the weed eater at a high rate of speed, went through my jeans and socks into my left lower leg. 5" wide cut into my leg and to the bone. Treated at Franklin Woods Emergency Room, later by Dr. Jeremy Elliott. That was on August 30th. Today, October 2, 2017, my leg is far from healing up. I now have appt. with Wound Care Center, Johnson City. I've had 5 doctor visits and my leg is still an open wound. I want medical costs covered plus damages. Also, to get product off the market before it hurts someone else.
