FLEXIBLE SHAFT SYSTEM HAVING INTERCHANGEABLE END EFFECTORS

摘要

Flexible shaft systems having interchangeable end effectors are described herein. A shaft with a flexibility sufficient to allow advancement through a lumen of an endoscopic device has an interface at its distal end for engaging a removable end effector tool. The shaft and end effector tool are configured to enable endoluminal deployment through a patient, e.g., through the esophagus and into the stomach. The removable end effector tool may comprise any number of different tools, such as graspers, forceps, scissors, snares, needles, etc., each being interchangeable upon the flexible shaft distal end. Once a procedure is done within the patient, the flexible shaft may be withdrawn and another distal end effector tool may be interchanged. The new end effector tool and flexible shaft can then be reintroduced into the patient.
