Abstract


  • A feasibility study on using polymer fiber Bragg sensors (PFBG) for providing force feedback to minimally invasive

    surgical devices is carried out. For this purpose a 3 mm long PFBG is fabricated and characterized for strain and

    temperature sensitivities. The PFBG sensor is then integrated onto a commercial laparoscopic clip applicator which is

    used as a proof of concept device. The force characterization of the clip applicator is carried out, with a replica setup

    which simulates the clip forming process of the device. An original clip is then formed without and with synthetic tissue

    samples of different hardness. The replica device force profile and original clip forming force profile follows the same

    pattern and thus the calibration data can be used to calculate the original force exerting on the tissues which can help in

    optimizing the clip formation process or can be used for providing force feedback capability to the device.
