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. The first rigid sheath can be completely removed from the main unit when the first connector portion is decoupled from the second connector portion. A different 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. A surgical tool kit includes a plurality of rigid sheaths having different shapes and having the ability to be removably attached to the main unit.

The surgical apparatus may find particular use with irrigation fluid, suction, and powering of a surgical tool. The passage may include a cutting blade retention assembly integrated in the passage.

Abstract: A surgical instrument includes a hollow cylindrical member having a flexible region along at least a part of the hollow cylindrical member and a malleable tubing disposed over at least an outer surface of the flexible region of the hollow cylindrical member. The flexible region and the malleable tubing disposed over the flexible region can bend multiple times. The malleable tubing can maintain a bent orientation until the malleable tubing is re-bent by a user. The surgical instrument also includes connections that prevent the malleable tubing from moving longitudinally relative to the hollow cylindrical member. The malleable tubing may be made of various materials, one example of which is anodized, annealed aluminum.
