1. An instrument for surgical training comprising:
a handle assembly that comprises:
a shaft assembly removably connected to the handle assembly, and
a handle that is operably connected to a proximal end of a movement arm,
wherein the shaft assembly includes a tool element at a distal end of the shaft assembly, a shaft, and a rod having a proximal end and a distal end connected to the tool element, wherein the rod is disposed inside the shaft of the shaft assembly, the proximal end of the shaft assembly is removably connected the distal end of the movement arm via the rod, and wherein actuation at the handle moves the movement arm and the rod of the shaft assembly to operate the tool element;
at least one sensor attached directly to the handle assembly and configured to acquire and transmit at least one relational data of the instrument with respect to a training environment during a training procedure, wherein the at least one sensor is configured to track user movements of the instrument during the training procedure; and
a computer system connected to the at least one sensor configured to receive, store, and process the at least one relational data and to output at least one feedback to a user after the training procedure based on processing of the at least one relational data,
wherein to process the at least one relational data comprises evaluating an economy of motion of a user performing a surgical procedure, the economy of motion calculated by:
calculating an average path length of other users performing the same surgical procedure as the user,
measuring a path length undertaken by the user during the surgical procedure, and
comparing the measured path undertaken by the user against the calculated average path length of the other users performing the same surgical procedure as the user via an equation:
