Assignee:

Ethicon Endo-Surgery, Inc. - Cincinnati OH

International Classification:

A61B 17/32

US Classification:

606169

Abstract:

A surgical instrument. The surgical instrument may comprise a transducer and an end effector. The transducer may be configured to provide vibrations along a longitudinal axis at a predetermined frequency and may comprise a piezoelectric stack positioned along the longitudinal axis. The transducer also may comprise a first metallic end mass positioned along the longitudinal axis adjacent a first end of the piezoelectric stack and a second metallic end mass positioned along the longitudinal axis adjacent a second end of the piezoelectric stack. The length of the transducer may be greater than or equal to of one wavelength and less than of one wavelength. The end effector may be coupled to the transducer and may extend along the longitudinal axis. The length of the transducer and the end effector may be a multiple of of one wavelength.

International Classification:

A61B 8/14

US Classification:

600471000

Abstract:

An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The assembly includes a clamping mechanism, including a clamp arm cam-mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces. The balanced blade provides a functional asymmetry for improved visibility at the blade tip and a multitude of edges and surfaces, designed to provide a multitude of tissue effects: clamped coagulation, clamped cutting, grasping, back-cutting, dissection, spot coagulation, tip penetration and tip scoring. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural axial motion of the user's index or middle fingers, whether gripping the surgical instrument right-handed or left handed.

International Classification:

A61B 17/32
B32B 37/12

US Classification:

606169, 156293

Abstract:

A tissue pad for use with an ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The tissue pad defines a first end and a second end and has a first surface adapted for engaging tissue against an ultrasonic end effector. The tissue pad defines a width dimension from the first end to the second end, and the width at the first end is greater than a second width located halfway between the first end and the second end. The second end has a width smaller than the width halfway between both ends.

International Classification:

A61N 7/00
B23Q 7/00

US Classification:

601 2, 29559

Abstract:

An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation and clamping of tissue during surgical procedures. An elongated portion of the instrument can be configured for endoscopic applications and has an outside diameter of less than 6 mm. The construction includes a clamping mechanism, including a clamp arm pivotally mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces, exceeding 4 pounds when the trigger is fully closed. The clamping mechanism includes a two-piece pad design and pad material that enables the higher tissue clamping forces and a force-limiting mechanism that effectively smooths out abusive tissue forces. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural swing of the surgeon's thumb, whether gripping the surgical instrument right-handed or left handed.

International Classification:

A61B 18/18

US Classification:

606 45

Abstract:

Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.
