Abstract
A cutting tool includes a cutting surface on a first side and an attachment member on a second side. The attachment member is configured to be coupled to a powered driving member. The cutting tool includes a limiting device configured to restrict the use of the cutting tool to a predetermined number of uses. The limiting device can be configured to restrict the number of uses of the cutting tool by restricting the number of times that the attachment member can be coupled to the powered driving member.

14. A cutting system comprising:
-
a cutting tool comprising a cutting surface on a first side of the cutting tool and an attachment member on a second side of the cutting tool; and a drive shaft having a receiving area and a coupling member, the receiving area being configured to receive the attachment member and the coupling member being configured to secure the cutting tool to the drive shaft, wherein the cutting tool comprises an integrated limiting device configured to restrict the number of uses of the cutting tool by restricting the number of times that the attachment member can be coupled to the powered driving member.

22. A method of restricting the number of uses of a cutting tool, the method comprising:
-
coupling an attachment member of a cutting tool to a receiving area of a powered driving member, the coupling of the attachment member to the receiving area comprising rotating the cutting tool relative to the powered driving member; causing, by the relative rotation of the cutting tool and powered driving member, an activation member on the cutting tool to contact a surface of the powered driving member, the contact of the activation member with the surface of the powered driving member causing the activation member to move from a first position to a second position; incrementing a counter on the cutting tool by the movement of the activation member from the first position to the second position; removing the cutting tool from the receiving area of the powered driving member; and restricting further coupling of the attachment member to the receiving area of the powered driving member once a predetermined number of incrementing steps have occurred. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. A method of determining an effective functional life of a medical cutting tool for cutting through bone, the method comprising:
-
(a) cutting through bone in a bone preparation area using the cutting tool; (b) measuring a temperature of the bone in the bone preparation area; (c) cutting through bone in a different bone preparation area; (d) measuring a temperature of the bone in the different bone preparation area; (e) repeating steps (a)-(d) until the temperature measured exceeds 50°
C.;(f) calculating the number of bone preparation areas that can be prepared using the cutting tool until the temperature in a respective bone preparation area exceeds 50°
C.; and(g) identifying the effective functional life of the cutting tool as the number calculated in step (f).
