摘要： An ultrasonic surgical blade with improved cutting and coagulation features is disclosed. The blade includes a solid body, a longitudinal portion having a proximal end configured to couple to an ultrasonic transmission waveguide and a transverse portion extending crosswise from the distal end of the longitudinal portion. At least one dissection edge and at least one hemostasis surface is provided on the blade. The transverse portion defines a hook having a free end configured to pull and dissect tissue. Also disclosed is an ultrasonic surgical blade that also includes a sharp central ridge and an end mass for acoustic balance.

摘要： A method of forming a component of an ultrasonic surgical instrument includes accessing a file including a digital model representing the component. The component includes a proximal portion and a distal portion. The proximal portion includes a contact portion. The distal portion includes an ultrasonic blade. The contact portion is configured to transmit ultrasonic vibrations to the ultrasonic blade when the component is acoustically coupled to a complementary portion of an acoustic waveguide of the ultrasonic surgical instrument. The file is used to fabricate the component via an additive manufacturing process. Once the component has been fabricated, the distal portion is secured to a distal end of the complementary portion of the acoustic waveguide.

摘要： An apparatus includes a body, a shaft assembly, and an end effector. The shaft assembly includes an outer tube, a proximal inner tube member, a distal inner tube member, and an acoustic waveguide. The end effector includes an ultrasonic blade and a clamp arm. A first portion of the clamp arm is pivotably coupled with a distal end of the outer tube. A second portion of the clamp arm is pivotably coupled with a distal end of the distal inner tube member. The outer tube is configured to removably couple with the body and the distal inner tube member is configured to removably couple with the proximal inner tube member such that the outer tube, the distal inner tube member, and the clamp arm are configured to removably couple with the body and the remainder of the shaft assembly and end effector as a unit.

摘要： Aspects of the present disclosure are presented for a surgical instrument for cutting and sealing tissue. In some embodiments, the surgical instrument includes a handle assembly, a shaft, and an end effector. The end effector may include: a blade that vibrates at an ultrasonic frequency, a shielded portion enclosing a back edge of the blade, a high-friction surface coupled to the shielded portion and positioned between the shielded portion and the back edge of the blade. A space is defined between the high-friction surface and the back edge of the blade when the end effector is in a cutting configuration. In a sealing configuration, the high-friction surface contacts the back edge of the blade, which generates heat based on ultrasonic vibrations of the blade rubbing against the high-friction surface. The shielded portion can coagulate bleeding tissue based on heat transfer from the high-friction surface to the shielded portion.

摘要： An ultrasonic surgical blade with an improved heel portion is disclosed. The blade includes a solid body, a longitudinal portion having a proximal end configured to couple to an ultrasonic transmission waveguide and a transverse portion extending crosswise from the distal end of the longitudinal portion. At least one dissection edge and at least one hemostasis surface is provided on the blade. The transverse portion defines a hook having a free end configured to pull and dissect tissue. The blade further comprises a tissue plow comprising a plow edge and a distal-most vertex to increase the efficiency of heel dissection and tissue diversion.

摘要： An apparatus includes a body, a shaft assembly, an end effector portion, a data storage component, a reader, and a use control. The shaft assembly extends distally from the body and includes a support portion. The end effector portion is configured to selectively couple with the support portion of the shaft assembly. The data storage component is associated with the end effector portion and contains data uniquely associated with the end effector portion. The reader is adapted to read the data from the data storage component. The use control is adapted to enable operation of the end effector portion if the data meets at least one usage parameter.
