Multifunctional surgical instrument

A multifunctional surgical instrument, comprising a housing, a trigger provided on the housing, an ultrasonic transducer provided within the housing, and a blade shaft assembly that transmits ultrasonic energy from the ultrasonic transducer and electrical energy generated by a system, wherein the blade shaft assembly comprises:

• a waveguide, with a proximal end thereof being fixedly connected to the ultrasonic transducer, and a distal end thereof extending out of the housing and forming an ultrasonic blade;
• a clamping arm, opened and closed relative to the waveguide by a first driving force;
• and
• a monopolar sleeve, sleeved on an outer side of the waveguide and axially moving relative to the housing under action of a second driving force.

A multifunctional surgical instrument, comprising a housing, a trigger provided on the housing, and a blade shaft assembly, wherein the blade shaft assembly is configured to selectively receive and transmit ultrasonic energy provided by an ultrasonic transducer through a switching mechanism located within the housing for cutting and hemostasis, or selectively transmit high-frequency electrical energy to achieve a function of a monopole high-frequency electrotome,

• wherein the blade shaft assembly comprises:
• a waveguide configured to transmit ultrasonic energy generated by the transducer;
• and
• a monopolar sleeve movable relative to the waveguide;
• wherein when an ultrasonic blade of the waveguide is located at the most distal end, ultrasonic energy is generated to perform cutting and hemostasis;
• and when the monopolar sleeve is located at the most distal end, high-frequency electric energy is transmitted to achieve the function of the monopole high-frequency electrotome.
