Abstract
Abstract A laparoscopic surgical instrument includes an actuation handle, a control member, a flexible tube, a rigid tube, and an end effector assembly. The control member extends through the flexible tube, and the actuation handle is coupled to the control member and the flexible tube. The end effector assembly is coupled to the control member and the flexible tube. The actuation handle is arranged to move the control member relative to the flexible tube, resulting in the operation of the end effector assembly. The rigid tube extends over the flexible tube and conforms the flexible tube to the shape and curve of the rigid tube. A set of rigid tubes, each curved to varying degrees, may be provided, wherein each tube may extend over the flexible tube and be removably coupled to the handle. The practitioner is able to choose from the variety of rigid tubes the tube which is most appropriate for a procedure. The practitioner is further able to change the instrument from one having a rigid tube of a first curvature to one having a rigid tube of a second curvature by uncoupling a first rigid tube and coupling a second rigid tube more appropriate for a given portion of a procedure.
