Abstract
A surgical device capable of interconnecting to an external motorized hand pieces, bending a distal end segment, rotating a window element positioned distal to the distal end segment and rotating independently of it, and actuating a cutting element positioned within the outer window element and rotating independently of it.
Claims20
A surgical instrument comprising:
- a flexible hollow drive shaft having a distal end and a proximal end;
- a handle disposed at the proximal end of the flexible hollow drive shaft;
- a cutting member affixed to the distal end of the flexible hollow drive shaft;
- a hollow bendable spine bearing comprising a continuous hollow tube concentrically disposed about the flexible hollow drive shaft, the continuous hollow tube extending from a proximal end at the handle to a distal end beyond the distal end of the flexible hollow drive shaft, wherein the hollow bendable spine bearing forms a bending segment adjacent to the distal end of the hollow bendable spine bearing;
- a tensioning member disposed about the hollow bendable spine bearing and extending between the distal end of the hollow bendable spine bearing and the handle for manipulating the bending segment of the hollow bendable spine bearing relative to the handle to provide curvilinear bending of the bending segment relative to the handle;
- a flexible outer tube concentrically disposed about the hollow bendable spine bearing and the tensioning member, the flexible outer tube having a proximal end and a distal end, wherein the flexible outer tube forms a cutting window at the distal end, and wherein the flexible outer tube is selectively rotatable about the hollow bendable spine bearing to position the cutting window adjacent to target tissue;
- and
- a high-speed drive operably coupled with the proximal end of the flexible hollow drive shaft for rotating the cutting member relative to the cutting window of the flexible outer tube.

A tissue resection device comprising:
- a housing containing a bending handle and a rotational knob;
- a concentric tubing assembly extending outward proximally-to-distally from the housing, the concentric tubing assembly comprising:
- a flexible outer tube having a proximal end operatively coupled with the rotational knob and a distal end forming a cutting window;
- a hollow bendable spine bearing disposed within the flexible outer tube, the hollow bendable spine bearing comprising a continuous hollow tube having a proximal end disposed adjacent to the bending handle, a distal end disposed adjacent to the cutting window, and a plurality of bendable bearing sections formed adjacent to the distal end of the hollow bendable spine bearing;
- a tensioning member disposed about the hollow bendable spine bearing within the flexible outer tube and extending from the distal end of the hollow bendable spine bearing to the bending handle, the tensioning member for manipulating the plurality of the bendable bearing sections relative to the bending handle to provide curvilinear bending of the plurality of the bendable bearing sections relative to the bending handle;
- and
- a flexible hollow drive shaft disposed within the hollow bendable spine bearing, the flexible hollow drive shaft having a proximal end operatively coupled with a high-speed drive and a distal end affixed to a cutting member, wherein:
- the tissue resection device provides the following independent degrees of freedom:
- rotation of the flexible outer tube via the rotational knob to position the cutting window relative to target tissue for resection, curvilinear bending of the plurality of the bendable bearing sections of the hollow bendable spine bearing via the bending handle, and rotation of the cutting member relative to the cutting window via the flexible hollow drive shaft and the high-speed drive.
