2D/4D/7D/12D/22D Hifu Cartridge

HIFU cartridges serve as the treatment heads for HIFU machines, allowing practitioners to perform targeted treatments on patients. They are designed to penetrate different layers of the skin, including the dermis and the superficial muscular aponeurotic system (SMAS), without damaging surrounding tissues. The main applications include:

• Facial rejuvenation: Reducing wrinkles and fine lines.
• Body sculpting: Tightening and lifting skin on various body parts.
• Vaginal rejuvenation: Enhancing vaginal tightness and elasticity.

Specifications

Types and Depths

HIFU cartridges come in various types, each with specific penetration depths and shot capacities. Here is a summary of common cartridge types:

Technical Specifications

• Frequency: Ranges from 2 MHz to 10 MHz depending on the cartridge type.
• Energy Output: Typically between 0.1J to 3Joules.
• Material Composition: Cartridges are generally made from glass and metal.
• Lifespan: Each cartridge can deliver between 10,000 to 20,000 shots before needing replacement

Usage Guidelines

Before using HIFU cartridges:

• Ensure that the cartridge is filled with water; this is crucial as water acts as a conductor for the ultrasound energy.
• Follow specific treatment protocols for different areas of the face and body to minimize risks and maximize effectiveness.

For example:

• The 1.5 mm cartridge is ideal for facial rejuvenation and treating superficial skin issues.
• The 4.5 mm cartridge targets deeper layers for more significant lifting effects

Replacement Frequency: Based on usage, practitioners may find that they need to replace the cartridges after completing the total number of shots. For instance:

• A cartridge with 10,000 shots would last for about 20 sessions at 500 shots per session.
• A cartridge with 20,000 shots would last for about 40 sessions under the same conditions.

What are the typical treatment depths for HIFU in different areas?

Facial Areas

• Forehead: Typically treated at a depth of 2 mm. This depth is effective for superficial lifting and rejuvenation.
• Cheeks and Jawline: Commonly targeted at 4.5 mm, which reaches the superficial musculoaponeurotic system (SMAS) layer, crucial for significant lifting effects.
• Periorbital Area (around the eyes): Often treated at 1.5 mm to 3 mm, focusing on fine lines and skin tightening without affecting deeper structures.
• Zygomatic Arches: Generally targeted at 4.5 mm to enhance contour and lift.

Body Areas

• Abdomen: Treatments usually occur at depths of 1.1 cm to 1.8 cm to effectively reduce subcutaneous fat and tighten skin.
• Thighs (Inner and Outer): Depths of approximately 1.3 cm to 1.6 cm are used, allowing for fat reduction and skin tightening in these areas.
• Flanks: Similar to the abdomen, treatments are typically performed at depths around 1.1 cm to 1.3 cm.

Summary of Treatment Depths

These depths allow HIFU to effectively target various tissue layers, including the dermis, SMAS, and subcutaneous fat, leading to desired outcomes such as skin tightening, lifting, and body contouring across different treatment areas

Maintenance Considerations: It’s essential to ensure that the cartridges are filled with water before use to maintain their functionality and prevent damage. Regular checks and proper maintenance can extend the life of the cartridges.

How many shots for treatment?

1. Facial Treatments: For facial rejuvenation, studies have shown that between 400 to 500 shots may be delivered during a session, depending on the size of the area being treated. This typically includes various facial regions, such as the jawline, cheeks, and perioral areas, which are often prioritized for lifting and tightening effects.
2. Body Treatments: In body contouring applications, the number of shots can also vary significantly. Practitioners may deliver a similar range of shots (around 500) for larger areas like the abdomen or thighs, depending on the specific treatment plan and patient needs.
3. Session Duration: Each HIFU session can last anywhere from 30 minutes to several hours, depending on the complexity of the treatment and the number of areas being addressed.

In summary, while the number of HIFU treatment shots can vary widely based on the specific application and treatment area, typical sessions may involve delivering between 400 to 500 shots for facial treatments and similar numbers for body contouring procedures.
