PLASMA SURGERY

 PLASMA SURGERY

Plasma surgery is a specific waveform of electricity through the dual-pole or multi-pole probe within the physical structure to stimulate blood, mucosal and soft tissue or nucleus pulposus within the binary compound (Nacl) molecules to get plasma state. Then the plasma high-speed charged particles directly interrupt tissue molecular bonds, and cause organization of protein to vaporize into H2, O2, CO2, N2, CH4 and other low mass gas.

Plasma Surgery techniques are achieved with the plasma energy released as the kinetic, thermal, and light energy.

• Kinetic energy allows for new uses of the device and an enhanced tissue effect.
• The thermal energy of the pure plasma energy allows for a high level of control over the tissue      effect with the minimal thermal diffusion
• Light energy provides enhanced visibility of surgical field.

Advantages of plasma surgery

• Low working temperature 40-70°C, to reduce the thermal injury to surrounding tissue
• Probe into the diseased area inside physique to create precise and efficient treatment
• Dual-polar or multi-polar design, no electrical current to travel through patient
• Almost no bleeding during surgery, short operation time
• Minimally invasive surgery, small trauma, quick recovery

THE PLASMA SURGICAL SYSTEM

The Plasma Surgery System utilizes mechanical energy and highly controlled thermal effects to treat tissue through three key surgical actions namely kinetic dissection, Microlayer Vaporization and surface sealing. It’s developed to leverage the unique properties of pure plasma energy and offer surgeons the flexibility to perform no-touch, atraumatic surgery. The Plasma surgical system may be a safe, effective, and easy-to-use device designed for a spread of surgical applications.

Thus plasma surgical system is employed for cutting, stripping, puncture, vaporization, haemostasis, ablation, shrinkage and surgical repair of soppy tissues in open and closed surgeries.

• Kinetic Dissection allows surgeons to form clean and dry tissue planes and open adhered areas on or near sensitive structures.
• Microlayer Vaporization enables surgeons to perform more complete disease removal from surface tissue, layer by layer.
• Surface Sealing allows surgeons to dry and seal areas with small vessels and oozing surfaces, reducing the danger of leakage and complications.

THE RADIOFREQUENCY PLASMA SURGICAL SYSTEM   

   The radiofrequency plasma surgical  system transfers radiofrequency energy to the lesion tissue for ablation, cutting, coagulation or haemostasis by using it.

Working principle of Radio frequency surgical system

The Surgical System adopts unique technology of controlling radio frequency emitting, whose power output can exactly produce plasma energy. Optimized power output can produce plasma energy effectively and speedily while minimize the thermal energy within the joints.

Ablate

The radio frequency energy flows through the active electrode and returns electrode, and by the conductive saline, it generates precisely focused plasma sheath round the electrodes. The plasma sheath consists of massive charged particles, which might generate sufficient energy of strong oxidizing when accelerated by the electrical field. The generated energy is powerful enough to interrupt the organic molecular bonds within the tissue, and make the tissue rapidly dissolved into molecular and atoms level at a comparatively vasoconstrictor of 40-70˚C. The device provides rapid and efficient ablation and resection capabilities of soppy tissues at relatively low temperatures.

Coagulate

When RF energy acts on tissue, including blood, round the electrode tip it generates Joule heat and electromagnetic radiation effect which providing an instantaneous coagulation of tissue protein and sealing of small blood vessels, thus coagulation and haemostasis capabilities of target tissues are realized.

The medical procedure by plasma ablation creates well-distributed coagulative necrosis for efficient haemostasis while preserving the mucosa and plant tissue. Compared thereto of conventional surgical methods, its post-operative recovery is improved.

Different from the past thermal coagulation by warm temperature, plasma technology can make the working temperature controlled at 40-70˚C, and coagulate helical structure of collagen molecules meanwhile preserving the cells vitality.

Temperature control

The surgery by plasma technology is performed at a controlled temperature of 40-70°. Because the frequency is conducted into the saline solution to make the plasma sheath instead of into the tissues themselves, there’s minimal heat damage with these systems. Using special temperature control technology, the system stays at the best temperature for a stable and effective output.

Systematic Working Mode

There are two working modes for Radio frequency plasma surgical system.

 ABLATE  for resection and ablation activated at Yellow panel and Yellow lever.

COAG  for coagulation and haemostasis activated at Blue control board and Blue pedal.

Enhanced Coagulation

Enhanced coagulation mode can improve haemostasis capability while providing clear surgical vision.

Intelligent system

Designed with automatic identification of electrode, foot switch and electric cord, displayed on the device instrument panel, and automatic default power output value for various electrode designs.

Automatic Protection

The circuit system can constantly monitor power output and automatically suspend power output when there’s instantaneous peak current. For instance, the generator will automatically suspend radio frequency output when electrode contacts or is near metal, and automatically resumes work after electrode has returned to a correct distance.

Bipolar and Multi-polar Technology

Various bipolar and multipolar electrode designs are available. Around the electrode tip, sufficient and stable plasma layer is generated for rapid resection, ablation, coagulation and haemostasis of soppy tissues.

Foot Switch

The waterproof, pressure-resistant and convenient foot control has two working modes of ABLATE and COAG, each identified in several colors and dealing sounds.

Integrated Function

In one versatile single-use electrode, it provides ABLATE for resection and ablation, COAG for coagulation and haemostasis, and suction capabilities. The integrated suction electrode enhances surgical vision, controlled resection for rapid removal of soppy tissue.

Temperature Control Technology

The medical procedure by plasma technology is performed at controlled 40-70˚C. It uses a controlled, non-heat driven process during which bipolar radiofrequency (RF) energy excites the electrolytes in a very conductive medium, usually normal isotonic solution, to make a precisely focused and charged plasma gas. The energized particles within the plasma have sufficient energy to interrupt the organic molecular bonds within tissue, causing tissue to dissolve at relatively low temperatures of 40-70˚C. Radiofrequency current doesn’t pass directly through tissues, causing minimal tissue thermal effect. By temperature control technology, the generator automatically optimizes output value in keeping with the plasma layer status round the electrode tip and also the target tissue feature, by which electrode can provide a stable and efficient capabilities while keeping rock bottom working temperature.

Timer

When the special electrode with time control is chosen, the generator automatically recognizes the electrode and starts to count the active time by 100ms.
