Abstract

Devices for electrosurgery by means of oxy-hydro combustion and methods for use of such devices in electrosurgical procedures. Provided are devices for combustion of oxygen and hydrogen, or other hydrocarbon fuels, wherein oxygen and hydrogen may be generated by electrolysis or oxygen and hydrogen, or other hydrocarbon fuels, may be supplied, such devices including an ignition source and an adjustable and translatable sheath for controlling such reactions. Also provided is a detachable and positionable sheath for controlling reactions and minimizing tissue damage with conventional electrosurgery devices.

Claims

1. A movable sheath adapted for use with a radiofrequency (RF) electrosurgical probe, comprising:

a generally cylindrical plenum with an open first end and an open second end and of a diameter such that the open second end may be co-axially placed over the electrode end of an RF electrical probe, whereby the open first end extends beyond the electrode end of the RF electrical probe; and

a flexible polymeric fixation sleeve for securing the position of the RF electrosurgical probe within the generally cylindrical plenum wherein the generally cylindrical plenum further comprises a plurality of perforations.

2. The sheath of claim 1 wherein the flexible polymeric fixation sleeve is fixed to the generally cylindrical plenum.

3. A movable sheath adapted for use with a radiofrequency (RF) electrosurgical probe, comprising:

a generally cylindrical plenum with an open first end and an open second end and of a diameter such that the open second end may be co-axially placed over the electrode end of an RF electrical probe, whereby the open first end extends beyond the electrode end of the RF electrical probe; and

a flexible polymeric fixation sleeve for securing the position of the generally cylindrical plenum to the RF electrosurgical probe wherein the movable sheath comprises a plurality of demarcations for determining the position of the movable sheath with respect to the electrode end of the RF electrical probe.
