Abstract
An ultrasonic surgical device for the application of ultrasonic energy is disclosed. The surgical device has a housing and an acoustic assembly having a solid core waveguide. The waveguide extends from the housing and has a novel end effector at the distal end for the conduction of ultrasonic energy thereto. Two novel end effectors are described having an embedding surface at the distal end, and a coagulating surface extending from the embedding surface. The first novel end effector has a cylindrical shaft, an embedding surface, and an angled coagulating surface. The second novel end effector has a truncated cone having a circumferential coagulating surface and a distal embedding surface.
Claims22
An ultrasonic surgical device and patch combination for repairing a defect in tissue comprising:
- a) a patch for placement over a defect in tissue;
- b) a housing;
- c) an acoustic assembly for the generation of ultrasonic energy, said acoustic assembly including a waveguide extending from said housing, said waveguide having a solid core;
- d) an angled surface end effector at a distal end of said acoustic assembly for the conduction of ultrasonic energy thereto, said end effector having:
- i) a cylindrical shaft,
- ii) an embedding surface at the distal end of said shaft, said embedding surface emulsifying tissue and embedding said patch into tissue upon a first application of energy thereto, and
- iii) an angled coagulating surface extending proximally from said embedding surface, said angled embedding surface angled from a longitudinal axis of said cylindrical shaft and angled outwardly from said embedding surface, said coagulating surface coagulating tissue and welding said patch to tissue upon a second application of energy thereto.
