Problems solved by technology

Additionally, aluminum is softer than titanium alloys and is more susceptible to damage by other surgical instruments during use, potentially causing a fracture initiation phase that can also reduce the fatigue resistance of the end effector
[0011] Clearly, the design of surgical ultrasonic end effectors is very complex, at least in part, because the available options for a single end effector material with a combination of acoustic and mechanical properties required for certain surgical applications are very limited

Embodiment Construction

[0035] Before elaborating the present invention in detail, it should be pointed out that the present invention in its application or use is not limited to the construction and arrangement of parts shown in detail in the drawings and detailed description. Exemplary embodiments can be implemented or incorporated into other embodiments, alterations and modifications, and can be implemented or carried out in various ways. Furthermore, the terms and formulas used herein were chosen for the purpose of describing the exemplary embodiments for the convenience of the reader and are not intended to limit the invention unless otherwise indicated.

[0036] see figure 1 , the exemplary ultrasonic surgical system 10 includes an ultrasonic signal generator 12 with an ultrasonic transducer 14 and a handpiece housing 16 . The ultrasonic transducer 14 converts the electrical signal from the ultrasonic signal generator 12 into mechanical energy that causes the ultrasonic transducer 14 and the u...

Abstract

An ultrasonic surgical system includes an ultrasonic transmission member having a proximal end and a distal end. An ultrasonically actuated end-effector is attached at the distal end of the transmission member. A pressurized fluid delivery system includes a fluid nozzle in communication with at least one fluid source. The fluid nozzle is arranged and configured to deliver pressurized fluid to soft tissue at a rate to move the soft tissue away from the end-effector during use.

Description

technical field [0001] The present invention relates generally to surgical systems, and more particularly to ultrasonic surgical systems. Background technique [0002] Ultrasound instruments are used by surgeons during surgery to cut and coagulate tissue. The piezoelectric element is electrically excited at the resonant frequency of the ultrasonic instrument to generate vibrations, which are transmitted through the resonator and amplified to generate mechanical standing wave vibrations at the same frequency. The ultrasound transmission assembly of the instrument has an elongated transmission waveguide that transmits the vibrations to an end effector (such as a cutting blade) at the distal end of the instrument. The end effector may vibrate primarily in the longitudinal direction to generate localized heat in adjacent tissue, but certain instruments have been specifically designed so that the end effector is primarily in the transverse (perpendicular to the longitudinal axis...
