Handheld medical devices including microwave amplifier unit at device handle

Abstract

A method of manufacturing a medical device includes the initial steps of providing a handle assembly and providing a microwave-signal-amplifying module. The handle assembly includes a handle body defining a chamber therein. The handle body is configured to support an energy applicator at the distal end thereof. The microwave-signal-amplifying module includes a microwave amplifier unit adapted to amplify a high-frequency input signal to generate a high-frequency output signal. The microwave-signal-amplifying module includes one or more connector portions including one or more electrical connectors adapted to be removeably coupleable to one or more electrical conductors associated with the handle body. The method also includes the step of positioning the microwave-signal-amplifying module into the chamber to bring the one or more electrical connectors of the one or more connector portions into electrical engagement with one or more electrical connectors associated with the handle body. The method discloses handheld medical devices including microwave amplifier unit at device handle.

Description

technical field [0001] The present disclosure relates to hand-held medical devices suitable for tissue ablation applications. More specifically, the present disclosure relates to medical devices having a microwave amplifier unit positioned at a handle of the device, electrosurgical systems including the medical device, methods of directing energy to tissue using the medical device, and methods of manufacturing the medical device. Background technique [0002] Electrosurgical instruments have been widely used by surgeons. Electrosurgery involves the application of thermal and / or electrical energy during surgical procedures to cut, dissect, resect, coagulate, cauterize, seal, or otherwise manipulate biological tissue. Electrosurgery is typically performed using a handpiece that includes a surgical instrument (e.g., an end effector or ablation probe) adapted to deliver energy to a tissue site during electrosurgery, a remote electrical A surgical generator and a cable assembly...

AI Technical Summary

Problems solved by technology

Stray leakage of microwave energy from cable assemblies can interfere with deployed wireless networks, patient monitoring, and other medical devices used in hospital environments

Cable assemblies add to the cost of producing and maintaining microwave surgical instruments

In addition, cable assemblies prevent the surgeon from having full freedom of movement during surgical procedures using electromagnetic radiation to manipulate tissue using hand-held instruments
