Aspects of the present disclosure include an attachable power and control system to supply energy to electrodes of a wiping electrode coagulation system of a surgical device. A surgical device includes electrodes at an end of effector to aide in sealing during various surgical procedures. During the procedure, the surgeon may wipe the surgical site with the end effector, causing the electrodes to touch the fractured area. Electrosurgical energy may be applied to the electrodes during the wiping, causing coagulation of smaller vessels. The attachable power and control system may be configured to slide over the shaft of the surgical device. The power and control system also may be configured to supply power to the electrodes and to control when energy is applied to the electrodes, based in part, for example, on measuring a distance or angle of the opening of the jaws at the end effector.
