Abstract

A mechanical cavity-creation surgical device and methods and kits for using such devices is described. In one variation, the mechanical cavity-creation surgical device contains a side window at the distal end of a shaft that allows the articulation of a blade, pick, or tip from a position that is inside the shaft to a position that protrudes at least partially from the side window.

Claims

1. A method of creating a cavity in a body region comprising:

inserting a distal portion of a shaft into a patient'"'"'s body;

rotating a cutting element within a lumen of the shaft which results in a distal portion of the cutting element protruding from a side window on the shaft, wherein the side window is located on a circumferential surface at a distal portion of the shaft; and

rotating the shaft axially to score or scrape a body region within the patient'"'"'s body to create a cavity.

2. The method according to claim 1, further comprising:

displacing the cutting element distally within the lumen of the cannula.

3. The method according to claim 2, further comprising having the cutting element engage a ramp.

4. The method according to claim 1, wherein inserting the distal portion of the shaft comprises inserting the distal portion of the shaft into a vertebral body through a pedicle.

5. The method according to claim 1, wherein the cutting element is a blade, tip or pick and the blade, pick, or tip is articulatable.

6. The method according to claim 5, wherein the blade, pick, or tip is made of a nickel titanium alloy.

7. The method according to claim 5, further comprising passing the shaft through a cannula.

8. The method according to claim 5, wherein the cavity is created in bone.

9. The method according claim 8, wherein the bone is a vertebra.

10. The method according to claim 5, wherein the shaft is not passed through a cannula.

11. The method according to claim 10, wherein the shaft also serves as a cannula.

12. The method according to claim 11 further comprising checking a surgical site with an endoscope to see if sufficient scoring and/or scraping has occurred.
