Abstract: An interface joint for interconnecting an electrosurgical generator and an electrosurgical instrument, the interface joint comprising: a housing having: an inlet for receiving electromagnetic energy from the electrosurgical generator, and an outlet; a slidable trigger on the housing, the slidable trigger being attached to a push rod that extends out of the housing through the outlet; and a single cable assembly for connecting the outlet to the electrosurgical instrument, the single cable assembly comprising a flexible sleeve that conveys the push rod and a coaxial cable that is connected to the inlet. The interface joint may include a reinforcement element coupled to a first portion of the push rod so as to reinforce the first portion. Additionally or alternatively, the interface joint may include a slide limiting mechanism coupled to the push rod and configured to limit a maximum slide distance of an internal tube over the push rod.

Abstract: In one aspect, the disclosure presents an electrosurgical instrument for performing haemostasis by radiating microwave energy from a distal tip, where conductive radiating electrodes are coated in an insulating non-stick material. In another aspect, the disclosure provides an electrosurgical instrument for performing haemostasis using radiofrequency or microwave electromagnetic energy, where a distal tip of the instrument comprises a conductive hollow needle for conveying fluid to or from a treatment site, wherein the hollow needle is electrically grounded.

Abstract: An electrosurgical apparatus for tightening ligaments using microwave energy. A detector is used to obtain information about a treatment zone. Based on this information, an energy delivery profile is determined. The energy delivery profile is selected to cause desired thermal effects in target tissue (e.g. ligaments, tendons or the like) without unwanted thermal side effects is determined and delivered. With this apparatus, energy can be delivered in a precise manner to the target tissue. The energy delivery profile may be based on a complex impedance, or attenuation and/or phase constants of the type of body tissue in the treatment zone.
