Embodiment Construction

[0056] Refer to the attached figure 1 , which illustrates a surgical assembly 100 for use in a surgical procedure, such as an electrosurgery, ultrasound or laser based surgical procedure, according to one embodiment of the present invention. Assembly 100 includes surgical tool 110, which may generally include a tool held by a surgeon for cutting and / or cauterizing tissue. In the illustrated embodiment, tool 110 includes a handle 111 and an elongated shaft 112 connected to handle 111 at its proximal end. Shaft 112 is formed of a dielectric material and includes an electrical conductor 113 extending through shaft 112 generally along its longitudinal axis. An electrical conductor 113 protrudes from the distal end of the shaft 112 and is thus electrically exposed, forming or being attached to a tool piece 114 responsible for transferring energy to tissue. The tool piece is shaped to facilitate surgical manipulation, and the tool piece may comprise, for example, wire formed as an...

Abstract

A surgical assembly and system are disclosed for use in performing a surgical procedure on a patient. The assembly comprises a surgical tool, the tool being arranged to receive a first signal for usein cutting or cauterizing tissue of the patient during the surgical procedure and an electrode disposed upon the tool. The assembly further comprises an electrical generator communicatively couplablewith the electrode, for generating a second signal for use in generating an electrical field from the electrode proximate a site of the surgical procedure, for removing particles suspended proximate the surgical site. The assembly further comprises a controller for controlling the application of the second signal to the electrode, a sensing arrangement for sensing an activation status of the firstsignal, the sensing arrangement being communicatively coupled with the controller and arranged to output a sensing signal to the controller in dependence of the activation status of the first signal.The controller is arranged to enable the application of the second signal to the electrode upon receiving a sensing signal representative of an activation of the first signal. An electrode assembly comprising a plurality of electrically conductive elements for use with a surgical tool is also disclosed.

Description

technical field [0001] The present invention relates to surgical assemblies, systems and electrode assemblies. Background technique [0002] Particulate matter in aerosol form is commonly encountered during surgical procedures. For example, the particulate matter may be used to deliver a therapeutic agent or may be generated as a result of performing a surgical procedure. Examples of particle-based therapeutics are agents delivered to effect rapid clotting of blood or to treat diseases such as cancer. A common example of particulate matter produced as a result of performing a surgical procedure is that produced when "energy type" surgical instruments are used. Energy-based surgical instruments are powered in some manner to achieve a therapeutic effect such as cutting or coagulating tissue. Although there are several modes of action such as radio frequency (RF), ultrasound, and laser, all of these energy-based devices generate particulate matter as a by-product of their mo...
