Powered surgical device
A surgical device incorporating a powered rotary cutting tool having a protective distal foot plate which protects against injuring non-target tissue enabling the rapid and safe removal of specifically-targeted bone, cartilage, and soft tissue.
1. A surgical instrument comprising:
an elongate receiver carriage support having a distal end;
a receiver carriage slidably coupled to said receiver carriage support, said receiver carriage including a rotary shaft having a cutting tool interface for removeably connecting a selected rotary cutting element having a periphery, said rotary shaft being aligned with said elongate receiver carriage support;
an actuator engaging said receiver carriage to impart linear displacement of said receiver carriage from a first position to a second position along said receiver carriage support and towards said distal end;
a foot plate coupled to the distal end of said elongate receiver carriage and positioned in alignment with said cutting tool interface, said foot plate defining a receiving channel which is sized and shaped to substantially conform to a size and shape of the selected rotary cutting element, said foot plate receiving said rotary cutting element and covering at least a portion of the periphery of said cutting element when said actuator is in said second position.
2. The surgical instrument of claim 1 wherein said foot plate further comprises an arcuate outer surface, said outer surface and said receiving channel defining a thickness of said footplate.
3. The surgical instrument of claim 1 further comprising an irrigation port proximate the distal end of the receiver carriage support, the irrigation port being coupled to a controllable source of irrigation fluid and being aligned to apply the irrigation fluid to the cutting element.
4. The surgical instrument of claim 1 further comprising a suction port proximate the distal end of the receiver carriage support.
5. The surgical instrument of claim 1 , further comprising an endoscope interface coupled to said receiver carriage for attaching an endoscope.
6. The surgical instrument of claim 1 , wherein the cutting element receiving channel of said foot plate defines a substantially hemispherically shaped channel corresponding to a contour of a substantially spherical cutting element.
7. The surgical instrument of claim 1 , wherein the actuator is a manually activated handle.
8. A surgical instrument comprising:
an elongate receiver carriage support having a distal end;
an irrigation port proximate the distal end of the receiver carriage support;
a suction port proximate the distal end of the receiver carriage support;
a receiver carriage slidably coupled to said receiver carriage support, said receiver carriage including a rotary shaft having a cutting tool interface for removeably connecting a selected rotary cutting element having a periphery, said rotary shaft being aligned with said elongate receiver carriage support;
an actuator engaging said receiver carriage to impart linear displacement of said receiver carriage from a first position to a second position along said receiver carriage support and towards said distal end;
a foot plate coupled to the distal end of said elongate receiver carriage and positioned in alignment with said cutting tool interface, said foot plate defining a substantially hemispherically shaped receiving channel which is sized and shaped to substantially conform to a size and shape of the selected substantially spherical rotary cutting element, said foot plate receiving said rotary cutting element and covering at least a portion of the periphery of said cutting element when said actuator is in said second position.
