Navigated malleable surgical instrument
First Claim
1. A surgical instrument, comprising:
- a body having a proximal end and a distal end, wherein the body is tubular-shaped and has a first internal flow channel extending between the proximal end and the distal end;
a sleeve distal to the body and having a proximal end and a distal end, wherein the proximal end of the sleeve is adjacent to and not in contact with the distal end of the body;
a tracking assembly adapted to cooperate with a navigation system to track a distal tip of the instrument, wherein the tracking assembly comprises a printed circuit board and a plurality of coils including a first coil, wherein each of the plurality of coils is wrapped around a respective one of a plurality of cores, and wherein the first coil is mounted on the sleeve;
a handle coupled to the proximal end of the body, wherein the handle comprises a second internal flow channel in fluid communication with the first internal flow channel;
a first pair of lead wires wound around the body from the tracking assembly to the handle;
a set of wires connecting the printed circuit board to the first coil, wherein the printed circuit board connects the first pair of lead wires to the set of wires; and
an insert received in the sleeve and the distal end of the body, wherein the insert is straight and tubular-shaped, wherein the insert is under at least a portion of the printed circuit board and prevents bending or flexing in a region of the printed circuit board, andwherein the insert provides rigid support for the sleeve and the distal end of the body, maintains alignment of the sleeve relative to the distal end of the body, and prevents bending of the sleeve and the distal end of the body.

Abstract
A surgical instrument can include a body, a tracking device, and a handle. The body can include proximal and distal ends, and a flow passage extending therebetween. The body can be formed from a malleable material such that it can be bent between the proximal and distal ends from a first configuration to a second bent configuration and maintain the bent configuration. The tracking device can be positioned adjacent the distal end for tracking a distal tip of the instrument. The handle can be coupled to the proximal end of the body and can include an internal flow passage in fluid communication with the body flow passage. The tracking device can include a pair of lead wires wound around the body to the handle, where the wound wires can conform to the bent configuration of the body such that they do not strain or break during bending of the body.
