Abstract

A device and method for a trackable suction tool in surgical use. A trackable suction tool involves a tubular handle with a main tube and an entrance tube extending from the main tube, a flattened section of the main tube with a suction-regulating orifice, a tip coupled with the main tube distal end and a tracking mechanism coupled with a handle proximal end. A method of tracking position of a trackable suction device involves attaching a tip to a handle in one of a plurality of fixed positions, attaching a tracking mechanism to the handle in one of a plurality of fixed positions, calibrating the position of the tip with a positional tracking system using the tracking mechanism, positioning the tracking markers in view of the positional tracking system, and tracking a position of the distal end of the tip of the suction device.

Claims17

Dependent claims

A trackable suction device, the device comprising:

an elongated tubular handle having a central passage, the elongated tubular handle comprising:
a main tube having a first proximal end, a distal end, and a flattened section, the flattened section having a suction-regulating orifice configured to communicate with the central passage;
and an entrance tube extending from the main tube and having a second proximal end;
an elongated tip having a hollow tubular body, a tip distal end, and a tip proximal end, the tip proximal end configured to detachably couple the tip with the main tube distal end by a tip attachment mechanism, the tip attachment mechanism configured to provide a plurality of fixed positions of the tip relative to the handle, and the tip attachment mechanism comprising a threaded ring and splines;
and
a reference tree for tracking the tip of the distal end of the suction device, the reference tree configured to:
detachably couple with one of the handle first proximal end and the handle second proximal end and couple with the handle by a reference tree attachment mechanism, the reference tree attachment mechanism configured to provide a plurality of fixed positions of the reference tree relative to the handle, and the reference tree attachment mechanism comprising a threaded ring and splines for tracking the tip of the distal end of the suction device;
wherein the tip attachment mechanism further comprises a threaded semi-captive nut, the threaded semi-captive nut further comprises:
a first internal thread configured to engage the tip proximal end;
a nut seating position configured to provide free rotation of the nut when the nut is engaged with the tip proximal end through the first internal thread to prevent the semi-captive nut from slipping from the tip during assembly and disassembly of the tip;
and
a second internal thread with a larger diameter than the first internal thread configured to engage the handle.
