Abstract
Various methods and devices are provided for cutting and sculpting body tissue, such as cartilage and the like, during a surgical procedure. In an exemplary embodiment, a surgical cutting device is provided which includes an elongate shaft and a rotatable tissue-affecting tip disposed at the distal end thereof. A lumen extends through both the shaft and the tip, and terminates in an opening formed in a distal end of the tissue-affecting tip.
Claims14
A surgical cutting device, comprising:
- an elongate shaft having a proximal end and a lumen extending therethrough along a longitudinal axis thereof;
- a rotatable, tissue-affecting tip disposed distally of the elongate shaft, the lumen extending through the tissue-affecting tip, along a longitudinal axis of the tissue-affecting tip, and terminating at an opening formed on a distal end of the tissue-affecting tip;
- and
- a plurality of cutting flutes formed in a solid, outer surface of the tissue-affecting tip,
- the lumen being adapted to evacuate particles of cut tissue from within a surgical environment surrounding the tissue-affecting tip.
2 more elements
A system for cutting tissue, comprising:
- a fluid-based drive system;
- and
- a surgical cutting device having an elongate shaft with a tissue-affecting tip having a plurality of cutting flutes formed in a solid outer surface thereof and disposed on a distal end of the elongate shaft, and with a lumen extending therethrough along a longitudinal axis and terminating at an opening formed on a distal end of the tissue-affecting tip, the lumen being adapted to evacuate particles of cut tissue from within a surgical environment surrounding the tissue-affecting tip, the tissue-affecting tip being rotatable in response to a force generated by the fluid-based drive system.
