Abstract
Description
Technical Field
[0001] This invention relates to the field of plasma medical equipment technology, and more particularly to a multifunctional plasma medical device for variable temperature applications using adjustable argon-helium mixed gas. Background Technology
[0002] Plasma medicine, as a promising field, demonstrates advantages in various therapeutic and surgical applications due to the unique properties of plasma. Traditional plasma medical devices typically use a single inert gas (such as argon (Ar) or helium (He)) or a fixed mixture of both to generate plasma; for example, argon plasma coagulation (APC) devices, due to their ability to generate relatively high-temperature plasma, are suitable for vascular closure and tissue ablation, and are widely used for hemostasis and tissue cutting. Cold atmospheric plasma (CAP) devices, on the other hand, typically use helium or a specific ratio of helium-argon mixture, operating at lower temperatures, and as research reports indicate, can be used for disinfection, wound healing, skin disease treatment, and even some cancer treatments.
[0003] Existing plasma medical devices have a significant limitation: their operating parameters are often fixed, especially the gas composition and the resulting plasma temperature. These devices are typically designed for "high-temperature" applications (such as coagulation) or "low-temperature" applications (such as dermatological treatment). This specialization necessitates the use of multiple devices or compromises in surgical flexibility—surgeons or clinicians must switch between different systems to achieve different plasma effects. Based on this situation, we propose a multifunctional plasma medical device for variable-temperature applications using an adjustable argon-helium mixed gas. Summary of the Invention
[0004] The present invention proposes a multifunctional plasma medical device for variable temperature application of adjustable argon-helium mixed gas to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: Adjustable argon-helium mixed gas temperature-controlled multi-functional plasma medical devices, including: Argon source, which is an argon gas storage device; Helium source, which is a helium storage device; A gas delivery system is fluidly connected to the argon source and the helium source, and the gas delivery system is used to independently adjust the flow rate and pressure of the argon and helium; A gas mixing chamber, fluidly connected to the gas delivery system, is used to mix regulated argon and helium in a user-adjustable ratio to form a mixed gas. An RF energy generator is used to generate the energy required to excite the gas mixture and is connected to the gas mixing chamber. The main control computer is communicatively connected to the gas delivery system, the gas mixing chamber, and the RF energy generator. The main control computer is used to control the flow rate, pressure, and mixing ratio of argon and helium, as well as the energy output of the RF energy generator. A handheld device, fluidly connected to the gas mixing chamber and communicatively connected to the RF energy generator, is used to receive the mixed gas, and to use the energy from the RF energy generator to excite the mixed gas to generate a plasma jet and emit it.
[0006] Preferably, the handheld device is a cold ion device, which also integrates a plasma temperature control mechanism. The plasma temperature control mechanism on the handheld device supports real-time adjustment of the plasma jet temperature during medical operations. The plasma temperature control mechanism is used by the user to adjust the ratio of argon to helium in the mixed gas via the main control computer, thereby adjusting the temperature of the emitted plasma jet.
[0007] Preferably, the cold ion device is equipped with a grounding plate, which is connected to the RF energy generator.

The cold atmospheric plasma is suitable for at least one of the following applications: cancer treatment, plastic surgery, skin healing, skin improvement, and antibacterial treatment, while the high-temperature plasma is suitable for surgical hemostasis.
[0009] Preferably, the main control computer is used to receive input signals from the plasma temperature control mechanism, and then adjust the argon flow rate, helium flow rate, or both simultaneously to achieve the desired plasma temperature.

The helium pressure regulating valve is fluidly connected to the helium source and the helium flow controller. The helium flow controller is fluidly connected to the gas mixing chamber and is controlled by the main control computer.

[0012] Compared with existing technologies, this invention provides a novel multifunctional plasma medical device that generates plasma with a wide temperature regulation range by precisely controlling the ratio of argon and helium. This allows a single device to achieve both low-temperature and high-temperature plasma applications, thus filling a gap in existing technologies. Attached Figure Description

The gas mixing chamber, which is fluidly connected to the gas delivery system, is used to mix regulated argon and helium in a user-adjustable ratio to form a mixed gas. An RF energy generator is used to generate the energy required to excite the gas mixture and is connected to the gas mixing chamber. The main control computer is connected to the gas delivery system, gas mixing chamber and RF energy generator. The main control computer is used to control the flow rate, pressure and mixing ratio of argon and helium, as well as the energy output of the RF energy generator. The main control computer is used to receive input signals from the plasma temperature control mechanism, and then adjust the flow rate of argon and helium or both at the same time to achieve the expected plasma temperature. The handheld device is fluidly connected to the gas mixing chamber and communicatively connected to the RF energy generator. It receives the mixed gas and uses the energy from the RF energy generator to excite the mixed gas to produce and emit a plasma jet. The handheld device is a cold ionizer, equipped with a grounding plate connected to the RF energy generator. It also integrates a plasma temperature control mechanism, which allows for real-time adjustment of the plasma jet temperature during medical procedures. This mechanism allows the user to adjust the ratio of argon to helium in the mixed gas via a main control computer, thereby regulating the emitted plasma jet temperature. This embodiment achieves a wide temperature range by precisely controlling the ratio of argon to helium, enabling a single device to perform both low-temperature and high-temperature plasma applications, thus filling a gap in existing technology.
[0016] Specifically, adjusting the ratio of argon to helium allows the plasma jet to switch between cold atmospheric plasma for therapeutic applications and high-temperature plasma for surgical applications. Cold atmospheric plasma is suitable for at least one of the following applications: cancer treatment, plastic surgery, skin healing, skin improvement, and antibacterial treatment, while high-temperature plasma is suitable for surgical hemostasis.

The helium pressure regulating valve is used to regulate the pressure of the helium gas supplied by the helium source, and the helium flow controller is responsible for precisely regulating the volume flow rate of helium gas entering the gas delivery system. The precisely regulated argon and helium gas are then introduced into the gas mixing chamber. S3: In the gas mixing chamber, regulated argon and helium are mixed in a user-adjustable ratio to form a mixed gas; S4: The RF energy generator excites the energy required to stimulate the mixed gas and generates a plasma jet, which is then delivered via a handheld device. S5: The plasma temperature control mechanism on the handheld device allows the user to adjust the ratio of argon to helium in the mixed gas via the main control computer, thereby regulating the temperature of the emitted plasma jet. This enables the plasma medical device to achieve both low-temperature and high-temperature plasma applications, thus filling a gap in existing technology.
