The description focuses on the physical and electrical properties of the device and its mechanism of action (helium gas plasma, arc discharge, cauterization). There is no mention of data processing, algorithms, or learning capabilities.
Yes
The device is designed to perform electrosurgical cutting and coagulation in soft tissue surgery, which are direct medical interventions aimed at treating conditions (e.g., stopping blood flow, cutting tissue).
No
The device is described as an electrosurgical cutting and coagulator used for therapeutic purposes (stopping blood flow, cutting tissue), not for identifying or characterizing health conditions.
No
The device description clearly outlines hardware components including a power generator control unit, a Helium gas supply, and an application probe, which generates a plasma flame for cutting and coagulation. This is not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "electrosurgical cutting and coagulator for use in all soft tissue surgery." This describes a device used during surgical procedures to interact directly with tissue for cutting and stopping bleeding.
- Device Description: The description details a device that generates a plasma flame to cut and cauterize tissue. This is a direct interaction with the patient's body during surgery.
- Lack of IVD Characteristics: An IVD device is used to examine specimens (like blood, urine, or tissue samples) outside of the body to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis of specimens.
The device described is a surgical instrument used for therapeutic purposes (cutting and coagulation) directly on the patient's tissue. This falls under the category of surgical devices, not in vitro diagnostics.

Device Description
The device is a helium gas electrosurgical coagulator for use in all soft tissue surgery-laparoscopic, endoscopic and open. It consists of two parts: a power generator control unit with a Helium gas supply and an application probe. An ionised gas plasma flame is generated in a controlled Helium gas flow at the end of a 4mm PTFE application tube (the probe). This produces a corona-type flame issuing from the open end of the probe with a high electron temperature but low molecular temperature of about 20C. When the probe is brought close (within 3 mm) to a surface connected to earth - such as human tissue - the corona-type flame changes to an arc discharge flame with a temperature of approx. 800C. The inert Helium gas flow in which the discharge takes place protects the area of discharge and minimises oxidation. This plasma flame can be used to stop blood flow from damaged tissue by cauterisation. The electrical generator provides an alternating current at a fixed frequency in the kilo hertz range with a power supply range of between 2 and 30W. The new probe is the LTC. This is a cutting probe where the 4mm PTFE tube retracts, exposing the point which is approximately 8-10mm long. This probe works by using the Corona flame passing between the point and the tissue at the nearest point which could be on the side of the probe. The point area which is hot then cuts through the tissue and cauterises small blood vessels as it passes through.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
In vitro comparison of the Helica thermal coagulator (HTC) and the argon beam coagulator (ABC); Dr. John Webb, Ph.D: The helium unit does have a much better control of the depth of necrosis than that of the ABC, but slightly less control over the width, perhaps due to the significantly greater power applied by the ABC to get the same effect. However, the judgement of effect of each of these unite while in use during surgery is visual and it will be easy to judge the spread of the effect and not easy to judge the depth. It can therefore be concluded that the use of the HTC should be easier than the AB, even given similar results, and the HTC should be considered "safer" with its much lower power at point of application.

It consists of two parts:
- A power generator control unit with a Helium gas supply. .
- . An application probe.
An ionised gas plasma flame is generated in a controlled Helium gas flow at the end of a 4mm PTFE application tube (the probe). This produces a corona-type flame issuing from the open end of the probe with a high electron temperature but low molecular temperature of about 20C. When the probe is brought close (within 3 mm) to a surface connected to earth - such as human tissue - the corona-type flame changes to an arc discharge flame with a temperature of approx. 800C. The inert Helium gas flow in which the discharge takes place protects the area of discharge and minimises oxidation.
This plasma flame can be used to stop blood flow from damaged tissue by cauterisation.
The electrical generator provides an alternating current at a fixed frequency in the kilo hertz range with a power supply range of between 2 and 30W.
Referring to the application probe, which the model is the LT, the L is for Laparoscopic and the T is the length.
The new probe is the LTC. This is a cutting probe where the 4mm PTFE tube retracts, exposing the point which is approximately 8-10mm long. This probe works by using the Corona flame passing between the point and the tissue at the nearest point which could be on the side of the probe. The point area which is hot then cuts through the tissue and cauterises small blood vessels as it passes through.
Statement of Intended Use:
"The device is a helium gas electrosurgical cutting and coagulator for use in all soft tissue surgery-laparoscopic ,endoscopic and open ".
Description of Modification:
The basic design of the Helica probe remains the same. However the handle of the LTC probe has been modified to allow the PTFE sheath to be retracted; this exposes the brass insert, which can then be used as a cutting instrument.
