PROBLEM TO BE SOLVED: To provide a surgical tool with a sheath which allows one surgical cutting tool (or blade) to meet requirements for the curvature of a tool and for the orientation of the cutting window of the tool.SOLUTION: A surgical tool 8 can include a main unit and a first rigid sheath 11. The main unit includes an inner tube 9 that is received within an outer tube 10. 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 various shapes and having the ability to be removably attached to the main unit. |
