2. Individual Product Principle, Biological Mechanism, Application & Differentiation

2.1 ESWT‑003(Type II) Mechanical Ballistic Shock Wave Device (AC-Powered)

Principle: This device generates ballistic shock waves via mechanical projectile impact. Kinetic energy from the accelerated projectile is converted into transient acoustic pulse energy. The acoustic pulse is transmitted through the applicator head and penetrates subcutaneous soft tissue, producing brief pressure fluctuation and mechanical micro-stimulation inside target tissue.Biological mechanism:

• Local mechanical micro-stimulation activates connective tissue cells, modulates fibroblast proliferation and promotes remodelling of extracellular matrix, helping improve tissue elasticity.

• Stimulates angiogenesis within the treatment area, enhances local microcirculation and accelerates the clearance of accumulated metabolic waste products.

• Modulates the excitability of nociceptive nerve endings, down-regulates abnormal pain signal transmission and relieves local tissue sensitization.Application scenarios: Auxiliary conditioning for chronic myofascial tightness, tendon strain discomfort, soft tissue stiffness induced by overuse, trigger point release of limbs and trunk. Widely adopted for post-sports recovery and chronic musculoskeletal maintenance at home.Target users: Fitness enthusiasts, amateur athletes, office workers with long-term myofascial tension, users with chronic tendon discomfort.Selection rationale & differentiation:

• Stable AC power supply guarantees consistent energy output during long sessions. Rated service life reaches up to 120,000 shock counts with wide adjustable energy range.

• Precision energy control: Multi-level amplitude adjustment, suitable for superficial fascia and deep tendon treatment, supports gradual energy escalation to accommodate different pain thresholds.

• Optimized ballistic projectile structure: Low friction design reduces wear, lowers failure rate and ensures long-term stable shock energy output.

• Ergonomic handheld applicator: Light weight, anti-slip grip, reduces operator fatigue during long-time operation.
