[0128] Other embodiments may include multiple end effectors 50 distally attached to a common ultrasound transmission waveguide 104 . The end effector 50 can provide various tissue effects similar to those described above with respect to the ultrasonic blades 120 , 150 , 180 , 210 , 230 . As noted above, the ultrasonic blades 120, 150, 180, 210, 230 may be detached (and have different components) from the waveguide 104 and joined, eg, by bolts, welding, glue, quick connects, or other known methods. Quick connect couplers can provide lower cost and convenience of using multiple ultrasonic blades 120, 150, 180, 210, 230 in one procedure.

[0129] As noted above, an end effector or blade of an ultrasonic surgical instrument, for example, may vibrate along a longitudinal axis to treat tissue. In each case, such instruments may eg preferably be configured such that they do not vibrate in any other direction, eg an axis transverse to the longitudinal axis. Such lateral vibrations, ...

Abstract

An ultrasonic surgical instrument including an ultrasonically actuated blade or end effector having a treatment portion. The blade can define a central axis and at least one axis which is transverse to the central axis, wherein the transverse axis can lie within a plane which is perpendicular, or normal, to the longitudinal axis and can define a cross-section of the treatment portion. Such a cross-section can include a central portion and a step extending from the central portion, wherein the central portion can comprise a width, and wherein the step can comprise a cutting edge. In at least one embodiment, the cutting edge can be defined by first and second surfaces which define an angle therebetween. In various embodiments, the position of the cutting edge and / or the angle between the cutting edge surfaces can be selected in order to balance the blade with respect to the transverse axis.

Description

Background technique [0001] Ultrasonic instruments, including both hollow-core and solid-core instruments, are used for the safe and effective treatment of many medical conditions. Ultrasonic instruments, particularly solid core ultrasonic instruments, are advantageous because they can be used to cut and / or coagulate organ tissue using energy in the form of mechanical vibrations transmitted at ultrasonic frequencies to a surgical end effector. Ultrasonic vibrations can be used to cut, resect, lift or cauterize tissue or separate muscle tissue from bone when delivered to organ tissue at a suitable energy level and using a suitable end effector. Ultrasonic instruments utilizing solid core technology are particularly advantageous due to the amount of ultrasonic energy that can be transmitted from the ultrasonic transducer through the waveguide to the surgical end effector. Such instruments may be used in open surgery or minimally invasive procedures, such as endoscopic or laparo...
