Embodiment Construction

[0073] The embodiments of the technology described herein provide various improvements to existing electrosurgical devices that allow the physical size of the device to be reduced to a size that allows the electrosurgical device to be actually used under the constraints of the laparoscopic surgical environment. One of the constraints of laparoscopic procedures involves the 5mm inner diameter opening provided by a commercial standard trocar. Devices compatible with 5mm opening constraints must have an insertable configuration with the largest diameter that can be inserted into the opening. The general purpose of the technical improvement is to create a high degree of efficiency with respect to device performance per unit volume or per unit cross-sectional area. For example, although the jaw set of the disclosed device has a small physical size, it can transmit an appropriate level of force to the tissue clamped by the jaw, and the structure and material of the jaw have sufficien...

Abstract

Embodiments of the disclosed technology relate to a bipolar electrosurgical devices, as well as methods of manufacture and use of such devices. Embodiments of the device may include a set of opposing jaws comprising at least one bipolar electrode pair disposed thereon, the set of jaws configured to deliver radiofrequency energy to a target tissue. In some embodiments, a standoff member is provided to maintain a physical gap between the pair(s) of electrodes.

Description

[0001] All publications and patent applications mentioned in this specification are incorporated herein by reference, and the degree of citation is as if each of the publications or patent applications has been specifically and individually incorporated by reference. Enter the same. Technical field [0002] The disclosed technology relates to devices, systems, and methods for electrosurgery. More specifically, the present technology relates to jaw structures used in such devices. Background technique [0003] Bipolar electrosurgical tools apply radio frequency (RF) energy to the surgical site where tissue is to be divided, removed, or coagulated. A specific application of these electrosurgical effects is to seal blood vessels or tissue pieces. A typical tool takes the form of a set of pliers or a pair of jaws, with one or more electrodes on the end of each jaw. During electrosurgical procedures, the electrodes are placed close to each other because the jaws are closed on the ta...
