Abstract

A tube can include an elongated cannulated member that has an external wall. The tube can be navigated during a selected procedure. The tube can be shaped to selected configurations. The tube can include a liner bonded to an internal wall. The liner can be formed to inhibit debris from the cannulated member from exiting the cannulated member.

Claims

1. A surgical instrument system for use during a selected surgical procedure, comprising:

a handle manipulable by a user;

a suction or irrigation tube connected to the handle and extending from a first end to a second end and having a first solid external wall and a first solid internal wall, a proximal end of the tube formed of a bendable and malleable aluminum tube; and

wherein the biocompatible liner member extends from the first end to the second end of the tube and includes a first liner extension portion extending around the first end of the tube from an internal surface to an exterior surface of the tube and a second liner extension portion extending around the second end of the tube from the internal surface to the exterior surface of the tube;

wherein the proximal end of the tube formed of the malleable aluminum tube is configured to be bent and shaped into various configurations to retain the bent or formed configuration without kinking or collapsing the first internal wall of the tube or the second internal wall of the biocompatible liner member; and

wherein the biocompatible liner member when bonded and fixed to the tube is wear and tear resistant to inhibit debris from the tube from exiting and passing through the tube when in use with the biocompatible liner member during suction or irrigation using the surgical instrument.

2. The surgical instrument system of claim 1, wherein the liner member is the preformed tubular liner member having a thickness of between about 0.127 mm to about 0.254 mm that includes a heat and pressure bond between the first internal wall of the tube and the second external wall of the liner member, wherein the first internal wall is a first etched internal wall to increase bonding strength with the second external wall.

3. The surgical instrument system of claim 1, wherein the tube includes:

a first proximal malleable aluminum tube;

a second distal tube inserted at least partially into one end of the first proximal malleable aluminum tube;

wherein an internal diameter through the tube is defined by the first proximal malleable aluminum tube and the second distal tube;

wherein the liner member is fixed on both the first internal wall of the first proximal malleable aluminum tube and a third internal wall of the second distal tube.

4. The surgical instrument system of claim 3, further comprising:

a tracking device;

wherein the tracking device is mounted on the second distal tube;

wherein the second distal tube is stiffer than the first proximal malleable aluminum tube.

5. The surgical instrument system of claim 4, further comprising:

a tracking system;

wherein the tracking system is configured to determine a location of the tracking device.

6. The surgical instrument system of claim 5, further comprising:

a navigation system including the tracking system and a display device;

wherein the navigation system is configured to illustrate the determined location of the tracking device relative to a subject.

7. The surgical instrument system of claim 3, wherein the second distal tube is a distal steel tube and is stiffer than the first proximal malleable aluminum tube.

8. The surgical instrument system of claim 1, wherein the malleable aluminum tube is bendable, wherein the biocompatible liner member is bonded and fixed to resist coming loose from the tube during bending.

9. The surgical instrument system of claim 1, wherein the liner member is formed from a polymer material having a thickness between about 0.127 mm to about 0.254 mm.

10. The surgical instrument system of claim 1, wherein the first external wall of the tube is covered by an exterior member formed from the liner member or another member.

11. The surgical instrument system of claim 10, wherein the another member is a heat shrink wrap.

23. The surgical instrument system of claim 1, wherein the malleable aluminum tube is AL 3003-O aluminum.

12. A surgical instrument system for use during a selected surgical procedure, comprising:

a first proximal malleable aluminum tube extending from a first end to a second end and having a first internal wall of a first diameter;

a second distal tube positioned at the first end of the first proximal malleable aluminum tube and having a second internal wall of a second diameter; and

a biocompatible liner member preformed as a tube and configured to be positioned in the first and second tubes and having a third external wall bonded and fixed to at least the first internal wall of the first proximal malleable aluminum tube and the second internal wall of the second distal tube throughout use of the surgical instrument system;

wherein the second distal tube is inserted at least partially into the first end of the first proximal malleable aluminum tube;

wherein the second distal tube is stiffer than the first proximal malleable aluminum tube;

wherein the first proximal malleable aluminum tube is configured to be bendable and the biocompatible liner member is bonded and fixed to the first and second internal walls of the first and second tubes to resist coming loose during bending of the first proximal malleable aluminum tube and wear and tear resistant to inhibit debris from the first and second tubes from exiting and passing through the first and second tubes when in use with the biocompatible liner member; and

wherein the proximal malleable aluminum tube is configured to be bent and shaped into various configurations to retain the bent or formed configuration without kinking or collapsing the first internal wall of the first proximal malleable aluminum tube or the second internal wall of the second distal tube.

13. The surgical instrument system of claim 12, wherein the first diameter is the same as the second diameter.

14. The surgical instrument system of claim 12, wherein the second distal tube is formed from a steel.

15. The surgical instrument system of claim 14, wherein the liner member is preformed from a polymer material having a thickness of about 0.127 mm to about 0.254 mm, wherein the liner member inhibits debris from the first and second tubes from exiting the first and second tubes throughout use of the surgical instrument system.

16. The surgical instrument system of claim 12, further comprising a tracking device mounted on the second distal tube.

19.
