Probe for a Plasma Flame Generating Apparatus
The present invention relates to an ionised gas plasma flame generating apparatus. In particular, the present invention relates to a probe for the ionised gas plasma flame generating apparatus. The described probe finds use in medicine and is particularly suitable for use within cauterisation procedures.
Background to the Invention
There exists apparatus for generating an ionised gas plasma flame suitable for medical use such as cauterisation. An example of such a device is disclosed in WO 98/35618. This apparatus produces a corona-type flame issuing from the end of a probe or nozzle. The corona flame has a high electron temperature but a low molecular temperature, typically about 20°C. When the probe is brought close to (within 5 mm of) a surface that is connected to electrical earth, either directly or by stray capacitance, the corona-type flame changes to an arc-discharge flame (which has a high molecular temperature typically of the order of 800°C). The flame takes place in the plasma provided by the flowing gas which, being inert, minimises oxidation occurring at the earthed surface.
Accordingly, when the surface is part of a human or animal body the plasma can be used to stop flow of blood from damaged tissue by cauterisation. Alternatively, the heat from the arc-discharge flame can be used to remove diseased or effected layers of tissue.
A key feature of the apparatus disclosed in WO 98/35618 is, it has electrical circuitry with a reactive component suitable for controlling cauterising apparatus at low powers, less than 5 W, which is desirable when performing some surgical techniques.
The apparatus, as described above, consists of a rigid probe. At the tip of the probe is where the ionised plasma flame forms. In practice, such the tip of such probes comprise a rigid conduit typically 50 to 300 mm in length such that they can be easily and directly manipulated by an operator to cauterise a region of choice, and surface areas of the human body.
Figure 1 illustrates the prior art plasma flame apparatus 1, which comprises a probe 2.
The probe 2 comprises a rigid conduit 3 and a flexible conduit 4. The plasma flame apparatus 1 further comprises an electrical conductor 5, electrical circuitry 6, a power supply 7 and a gas supply 8.
When employed to cauterise an internal surface 9 of, for example, a human body 10, the rigid conduit 3 enters the human body 10 at a keyhole point of entry 11. More specifically, the internal surface 9 could be the surface of an organ 12 within the human body 10. The rigid conduit 3 has a distal 13 and proximal 14 end. To cauterise a specific region of the internal surface 9, a portion of the rigid conduit 3 is required to extend out of the human body 10 such that a user can still manoeuvre the internal, distal end 13 of the rigid conduit 3 by manipulating the external, proximal end 14 of the rigid conduit 3. In practice, this arrangement limits the internal surfaces 9 that can be cauterised by plasma flame apparatus 1.
When performing keyhole surgery, plasma flame apparatus 1 is suitable when there is a direct line of sight from a keyhole point of entry 11 into the human body 10, to the internal surface 9 of interest. When this is not the case, such that there is not a direct line of sight into the human body 10, the above described plasma flame apparatus 1 cannot adequately cauterise the internal surface 9 of interest without more invasive, non-keyhole surgery. Access may be provided by creating a larger incision into the human body 10.
However, such non-keyhole surgery is undesirable as may result in a longer recovery time and an increased risk of infection.

In the description which follows, like parts are marked throughout the specification and drawings with the same reference numerals. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of embodiments of the invention.
Detailed Description of the Preferred Embodiments
An explanation of the present invention will now be described with particular reference to Figure 2.
A plasma flame apparatus 15, as shown in Figure 2, comprises a probe 16. The probe comprises a rigid conduit 17 and a flexible conduit 4. The probe 16 is powered by a power supply 7. The probe 16 and power supply 7 are connected by an electrical conductor 5, and electrical circuitry 6, which controls the plasma flame apparatus 15 at low powers such that it is suitable for cauterisation procedures. The electrical conductor 5 extends through the probe 16 as is housed within the rigid conduit 3 and flexible conduit 4.
A gas supply 8 feeds the probe 16 with a gas. The gas passes through the flexible conduit 4 and rigid conduit 17. The gas is an inert gas with a low breakdown potential such as hydrogen (H2), argon (Ar), neon (Ne), nitrogen (N2), helium (He), carbon dioxide (CO2) or any combination of these. The gas may also include a small amount (less 25%) of oxygen (O2).
The rigid conduit 17 is shorter in length when compared with the rigid conduit 3 known in the art. The rigid conduit 17 is typically between 10 to 25 mm long. Preferably the rigid conduit 17 is 15 mm long.
The rigid conduit 17 has a distal 18 and proximal 19 end. This distal end 18 is where the plasma flame forms and the proximal end 19 is attached to the flexible conduit 4.
In use, the probe 16 enters a human body 10 at a keyhole point of entry 11. The probe 16 typically has a diameter in the range 2 to 6 mm, which is commensurate with the diameter of the keyhole point of entry 11. Preferably, the probe 16 has a diameter of 4 mm.
The rigid conduit 17 of the probe 16 may be fully inserted within the human body 10 such that the flexible conduit 4 of probe 16, also partially enters the human body 10.
To manipulate the rigid conduit 17 of the probe 16 within the human body 10, there is provided, via a second keyhole point of entry 20, a robotic arm 21. At the end of the robotic arm 21 there is a manipulation fixing 22 which facilities the control, position and orientation of the distal end 18 of the rigid conduit 17.
The manipulation fixing 22 provides a means of attachment to the rigid conduit 17. It may take the form of a grabber which can grip the rigid conduit 17, analogous to a human hand, see Figure 3. Alternatively, the manipulation fixing 22 may take the form of a magnet or a “slot and clip” fixing.
Figure 2 shows the robotic arm 21 operated remotely by a remote control system 23. The remote control system 23 may take the form of computer software which can be programmed by a user, such as a surgeon. Alternatively, the remote control system 23 could take the form of mechanical controls which translate a user’s movements to the robotic arm 21 and manipulation fixing 22. The mechanical controls could be engineered to amplify or reduce the user’s movement when translating this movement to the robotic arm.
In addition, the remote control system 23 may also control the operation of the probe 16 of the plasma flame apparatus 15. More specifically, a user, such as a surgeon, could power up the probe 16 for a specified duration using the remote control system 23.
The robotic arm 21 facilitates manoeuvring the rigid conduit 17 of the probe 16 such that it can cauterise an internal surface 24 where there is no direct line of sight from the keyhole point of entry 11 into the human body 10, to the internal surface of interest 24. More specifically, the internal surface 24 could be the surface of an organ 12 within the human body 10.
In addition, the robotic arm 21 facilitates cauterising an internal surface 25 where, although there may be a direct line of sight from the keyhole point of entry 11, the internal surface of interest 25 would be harder to reach in comparison to internal surface 9. For example, an internal surface 25 which is hard to reach could be considered where the direct line of sight is tangential, or approaching tangential, to the internal surface 25 of interest.
In an alternative embodiment, instead of the robotic arm 21 entering via a second keyhole point of entry 20, the robotic arm 21 could share the same keyhole point of entry 11 as the probe 16.
In addition, to reach all the internal surfaces of interest 9, 24 and 25, there may be other keyhole points of entry 26 into the human body 10 that can be used by the probe 16 and or the robotic arm 21.
In a further alternative embodiment, there may be multiple robotic arms 21,27 which could use any combination of keyhole points of entry 11,20 and 26 to the human body 10. As shown by Figure 4, a second robotic arm 27 could hold a viewing camera 28 to provide the user with real time feedback on the cauterisation of internal surface 24. The second robotic arm 27 would also be connected to the remote control system 23.
There are numerous advantages to a plasma flame apparatus 15 comprising a probe 16, in accordance with the present invention. A short rigid conduit 17 of the probe 16 can be more easily manoeuvred and or orientated within a human body 10 in comparison to a longer rigid conduit 3 of probe 2. Thus, a short rigid conduit 17 enables cauterisation of internal surfaces 24, 25, which are impossible or difficult to reach with longer rigid conduit
3. This avoids the need for invasive, non-keyhole surgery, minimising the patient recovery time and reducing the risk of infection. Manipulating the probe 16 with a robotic arm 21 is advantageous as facilitates greater control, precision and dexterity in comparison to direct manipulation of the prior art probe 2 by an operator. An advantage of using a different keyhole point of entry 20 for the robotic arm 21 is it maximises the number of internal surfaces accessible by the probe 16. Alternatively, an advantage of the probe 16 and robotic arm 21 sharing the same keyhole point of entry is it minimises and the number of keyhole points of entry 11,20 into the human body 10. Advantages of having a second robotic arm 27 (or even multiple robotic arms) is it facilitates the deployment of hardware for real time feedback for a remote operator, improved diagnosis of internal surfaces (9,
24, 25) and even multi probes 16.
A plasma flame apparatus probe is disclosed. The probe finds use in medicine and is particularly suitable for use within cauterisation procedures. The plasma flame apparatus probe comprises a rigid conduit having a length between 10 to 25 mm. This has the advantage that it can be more easily manoeuvred and or orientated within a human body in comparison to probes comprising a longer rigid conduit, as known in the art. Thus, a short rigid conduit enables cauterisation of internal surfaces which are impossible or difficult to reach with a longer rigid conduit. This reduces the need for invasive, nonkeyhole surgery, minimising the patient recovery time and minimises the risk of infection. Manipulating the probe with a robotic arm is advantageous as facilitates greater control, precision and dexterity in comparison to direct manipulation by an operator.
The foregoing description of the invention has been presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise form disclosed. The described embodiments were chosen and described in order to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best utilise the invention in various embodiments and with various modifications as are suited to the particular use contemplated. Therefore, further modifications or improvements may be incorporated without departing from the scope of the invention as defined by the appended claims.
