Abstract:
An electrosurgical blade (900) configured to couple to an RF electrosurgical instrument (100). The electrosurgical blade (900) includes a proximal portion (900a) configured to couple to a blade receptacle (104) of an RF electrosurgical instrument (100), a coagulation section (920) extending distally from the proximal portion (900a), a blade edge (940) defined around a periphery of the electrosurgical blade (900), and a ramped surface (930) extending between the coagulation section (920) and the blade edge (940). The blade edge (940) includes a right-angled tip (944) and is defined by a first side (941) extending longitudinally, a second side (942) extending longitudinally and having a curved portion (942c), and a distal side (943) extending laterally.
