Driving devices and methods for determining material strength in real-time

A system comprising:

• an instrument having a working tool configured to penetrate a tissue;
• a sensor configured to generate in real-time one or more torque signals related to torque of the working tool;
• an axial drive motor;
• one or more motors housed in a body of the instrument, wherein the body further comprises one or more guides operatively coupled to the axial drive motor, wherein the one or more guides comprises a guide harp having a distal guide element configured to receive the working tool therethrough, wherein the guide harp comprises one or more rods providing support to bear a load of the instrument, wherein the one or more rods exit through a back end of the body;
• a controller in operative communication with the sensor and configured to receive the one or more torque signals, wherein the controller processes the torque signals into one or more processed signals representative of torque, energy, power or a combination thereof;
• and
• a display providing to the user in real-time the one or more processed signals.
