INSERTABLE ENDOSCOPIC INSTRUMENT FOR TISSUE REMOVAL

摘要

PROBLEM TO BE SOLVED: To provide an improved endoscopic instrument that increases the precision and speed of polyp removal for biopsy.SOLUTION: An improved flexible endoscopic instrument precisely and efficiently obtains samples of flat polyps and multiple polyps from a patient by debriding one or more polyps and retrieving the debrided polyps without having to alternate between using a separate cutting tool and a separate sample retrieving tool and may be used with an endoscope. In one aspect, the cutting tool is coupled to a flexible torque coil 4080 that is configured to transfer rotational energy from a powered actuator through the whole length of the endoscope onto the cutting tool.SELECTED DRAWING: Figure 42
