Abstract
A multiple mode cutting head is described having a closed configuration in which no cutting edge is presented. The multiple mode cutting head also has an off central axis inner cutting head with two radially separated scalloped cutting edges. An opening in an outer head has two straight cutting edges positioned for interaction with the scalloped edges during rotation of the inner cutting head.
Claims17
A surgical cutting head, comprising:
- a proximal end having a handle,
- a distal end having a cutting head with an outer cutting head having an opening and two straight cutting edges and an inner cutting head positioned for eccentric rotation relative to the opening and in cutting relation to the two straight cutting edges.
A method of removing bone, ligament, muscle, soft tissue, calcified tissue, scarred tissue, tumor, or other targeted issue, comprising
- advancing a device comprising a cutting head with an outer cutting head having an opening and two straight cutting edges and an inner cutting head positioned for eccentric rotation relative to the opening and in cutting relation to the two straight cutting edges to a target tissue;
- selecting one or more cutting parameters based on properties of the target tissue;
- and
- rotating the inner cutting head relative to the outer cutting head, thereby removing tissue from the target tissue.
