Surgical cutting tool
View Patent ↗The present invention pertains generally to a surgical tool for cutting and shaping bone, cartilage and other anatomical structures. In particular, described herein are surgical tools having at least two cutting surfaces.
1. A method of using a surgical device for cutting and removing target tissue of an articular joint such as cartilage and bone within a body, said method comprising:
cutting tissue of the joint in a first direction with a cutting element having a first cutting surface,
cutting tissue of the joint in a second direction with a second cutting surface of the cutting element, wherein the second direction is generally opposite the first direction and the second cutting surface is generally opposed to the first cutting surface such that the cutting surfaces cut tissue when the device is pushed or pulled along the target tissue; and
wherein the cutting of the joint tissue with the first and second cutting surfaces results in a smoothing of an articular surface that is substantially devoid of ridges and protuberances.
2. The method of claim 1 , wherein said cutting tissue of the joint in a first direction further comprises pushing said cutting element wherein said first cutting surface is a blade.
3. The method of claim 1 , wherein said cutting tissue of the joint in a second direction further comprises pulling said cutting element wherein said second cutting surface is a blade.
4. The method of claim 1 , wherein said cutting tissue of the joint in a first direction further comprises pushing said first cutting surface in a first direction along the target tissue and said cutting tissue of the joint in the second direction further comprises pulling said second cutting surface in a second direction along the target tissue wherein said first cutting surface and said second cutting surface are blades.
5. The method of claim 1 , wherein said cutting tissue of the joint in a first direction further comprises pushing said cutting element wherein said first cutting surface is an abrasion surface.
6. The method of claim 1 , wherein said cutting tissue of the joint in a second direction further comprises pulling said cutting element wherein said second cutting surface is an abrasion surface.
7. The method of claim 1 , wherein said cutting tissue of the joint in a first direction further comprises pushing said first cutting element having an abrasion surface in a first direction along the target tissue and said cutting tissue of the joint in the second direction further comprises pulling said second cutting surface in a second direction along the target tissue wherein said first cutting surface and said second cutting surface are abrasion surfaces.
