Endoscopic Polyp Measurement Tool and Method for Using the Same

摘要

An endoscopy tool for measuring a size of a polyp observed on an internal wall of a body cavity being scanned by an endoscope is provided. The tool is inserted within the body cavity via a service/working channel of the endoscope. The tool has at least a scaled catheter portion having markings for determining a distance of the polyp from a tip of the endoscope; and an operating portion having an elongate member connected to a biopsy tool. The scaled catheter portion has a proximal and a distal end. The elongate member has a distal end and a proximal end coupled with the distal end of the scaled portion. The biopsy tool is connected to the distal end of the elongate member. The determined distance is used for measuring the size of the polyp by an image processing module coupled with the endoscope.

1. An endoscopy tool for measuring a size of a polyp observed on an internal wall of a body cavity being scanned by an endoscope, wherein the endoscopy tool is adapted to be inserted within the body cavity via a channel of the endoscope, the endoscopy tool comprising:
a scaled catheter portion having a plurality of markings for determining a unit of distance within the body cavity, wherein the scaled catheter portion has a proximal and a distal end; an operating portion comprising an elongate member coupled with a biopsy tool, wherein the elongate member has a distal end and a proximal end coupled with the distal end of the scaled portion and wherein the biopsy tool is coupled with the distal end of the elongate member; and a processing unit adapted to determine the unit of distance from said plurality of markings using a scale conversion and to transmit data to a display, wherein said data is indicative of the unit of distance.
