Abstract: A method of performing a surgical procedure with a surgical tool assembly includes inserting a surgical tool into a passage of a patient. The surgical tool can include a main unit and a first rigid sheath. The main unit includes an inner tube that is received within an outer tube. The first rigid sheath removably receives the main unit. The surgical tool can be removed from the passage of the patient, and the first rigid sheath can be completely removed from the main unit. A second rigid sheath having a different shape from the shape of the first rigid sheath can then be removably attached to the main unit instead of the first rigid sheath.

The first rigid sheath removably receives the main unit. The surgical tool can be removed from the passage of the patient, and the first rigid sheath can be completely removed from the main unit. A second rigid sheath having a different shape from the shape of the first rigid sheath can then be removably attached to the main unit instead of the first rigid sheath.

Abstract: A blade assembly comprising: a tip including two or more tubes, wherein the two or more tubes include at least: an outer tube and an inner tube; and a mechanical enclosure including: a locking spline having a longitudinal axis; and a slide lock; wherein the slide lock slides along the longitudinal axis of the locking spline and over the locking spline forming a locked state so that rotational movement of the locking spline, around the longitudinal axis of the locking spline, is prevented; and wherein the outer tube is coupled to the locking spline so that rotational movement of the outer tube, around the longitudinal axis of the locking spline, is prevented during the locked state.

Abstract: A surgical tool can include a main unit and a first rigid sheath. The main unit includes an inner tube that is received within an outer tube. The first rigid sheath removably receives the main unit and connects to the main unit via a coupling between a first connector portion of the main unit and a second connector portion of the rigid sheath.
