1. An apparatus, comprising:

  • a housing defining an interior cavity extending through an entire longitudinal length of the housing, the interior cavity configured to receive an elongated shaft of a laparoscopic tool;

    wherein the laparoscopic tool comprises;

    the elongated shaft, anda surgical tool positioned at a distal end of the elongated shaft, the surgical tool comprising a first distal member coupled to a second distal member at a first pivot point on the laparoscopic tool, wherein the first distal member comprises a first inner surface configured to contact a body part during a surgical procedure and a first outer surface opposite the first inner surface, and the second distal member comprises a second inner surface configured to contact the body part during the surgical procedure and a second outer surface opposite the second inner surface;

    the apparatus further comprising;

    a first pivotable member and a second pivotable member coupled to each other at a second pivot point, wherein the first pivotable member is configured to engage and move with the first outer surface of the first distal member of the laparoscopic tool, and the second pivotable member is configured to engage and move with the second outer surface of the second distal member of the laparoscopic tool;

    a first anchoring device coupled to the housing, the first anchoring device configured to secure the housing around the elongated shaft of the laparoscopic tool; and

    a sensor coupled to the first pivotable member and the second pivotable member, the sensor configured to detect a relative movement of the first pivotable member and the second pivotable member about the second pivot point and to generate a signal based at least in part on the relative movement.
