An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.

A microwave antenna having a curved configuration is described herein. The antenna portion is formed into various shapes whereby the antenna substantially encloses, by a partial or complete loop or enclosure, at least a majority of the tissue to be irradiated. When microwave energy is delivered through the antenna, the curved configuration forms an ablation field or region defined by the curved antenna and any tissue enclosed within the ablation region becomes irradiated by the microwave energy. The microwave antenna is deployed through one of several methods, and multiple curved antennas can be used in conjunction with one another. Moreover, RF energy can also be used at the distal tip of the antenna to provide a cutting tip for the antenna during deployment in tissue.

Endoscopic vessel harvester with gyrosensor on handle for rotating camera view

Номер: US20220022948A1
Автор: Randal J. Kadykowski, Tatsunori Fujii
Принадлежит: Terumo Cardiovascular Systems Corp

An endoscopic vessel harvesting tool uses an optics system to present of a video image to a user. As the tool is manipulated around all sides of the vessel to dissect and cut surrounding tissue and side branches, the orientation of the captured image rotates. A motion tracker (e.g., gyrosensor) in the tool detects the rotation. By detecting a rotational angular velocity of the harvester handle during the harvesting procedure, the camera view orientation is compensated before display to the user. When the handle is rotated, the detected rotation is used to provide an opposite (canceling) rotation of the camera view so that a steady orientation is presented on the display. Thus, a vertically upward direction (or any other desired reference direction) remains substantially fixed in the displayed video images.

Принадлежит: MegaDyne Medical Products Inc

A portable, battery powered electrosurgical wave generator is usable in performing electrically driven medical procedures. The wave generator can be small and lightweight to enable a user to carry and use the wave generator in non-operating room type settings. The wave generator can include a control unit that generates output signals in each of a cutting mode, coagulation mode, and a bipolar mode. The control unit can use a single circuit structure to generate the output signals for the cutting, coagulation, and bipolar modes. The output signals can be generated solely from a voltage produced by an incorporated battery within the generator.
