Abstract
An ultrasonic surgical tool (100), a mountable ultrasonic surgical tool assembly, and a surgical robot system (300, 1300). The ultrasonic surgical tool (100) comprises: a knife shank assembly (110), located at a distal end of the ultrasonic surgical tool (100), the knife shank assembly (110) comprising a knife shank (111); an ultrasonic transducer (120), coupled to a proximal end of the knife shank (111) so as to output vibration to the knife shank (111); and a mounting assembly component (130), connected to the knife shank assembly (110) and used to mount or demount the ultrasonic surgical tool (100). The mountable ultrasonic surgical tool assembly comprises an auxiliary surgical tool (200), and an assembly head (220) of the auxiliary surgical tool (200) is detachably connected to the mounting component (130) of the ultrasonic surgical tool (100). The surgical robot system (300, 1300) comprises at least one robotic arm (311, 1311) and the mountable ultrasonic surgical tool assembly. The surgical robot system (300, 1300) can increase the output power of the ultrasonic surgical tool (100).
