Abstract
Aspects of the present disclosure are presented for a surgical instrument for cutting and sealing tissue with a mode selection assembly. The mode selection assembly allows for a user to safely activate or disable a cutting functionality and a sealing functionality through use of electrosurgical energy. In some embodiments, the mode selection assembly allows for a more automated application of the electrosurgical energy and the cutting functionality when applied to a surgical site. The mode selection assembly may also include a knob configured to switch between the aforementioned settings. Various control mechanisms are also disclosed to lock and unlock the cutting element, such as a motorized locking mechanism, a solenoid locking mechanism, a mechanical mechanism and use of a nitinol wire. The inclusion of the mode selection assembly allows for a user to more safely utilize the surgical instrument by intentionally disabling functionality that may otherwise be inadvertently activated.
