Pilling Weck Heiss Retractor | Model 54640 | Self-Retaining Automatic Frame Assembly | Four-Prong Blunt Tip Configuration | 4.0 Inch Nominal Total Length (10.2 cm) | Low-Profile Soft Tissue Exposure Element | Pre-Owned Hospital Surgery Asset (1/EA)

The Pilling Weck 54640 is a professional-grade, hospital-level surgical instrument expertly engineered to provide hands-free, self-retaining soft tissue retraction during plastic, hand, podiatric, and minor orthopedic procedures. Part of the specialized Heiss-pattern instrumentation family within the Teleflex/Pilling portfolio, this automatic retractor eliminates the need for manual tracking by utilizing an inline mechanical ratchet or spring-lock mechanism to hold its arms rigid at any custom expansion window. The active working ends feature a 4 x 4 configuration, with four blunt prongs measuring 8 mm in length on each side. This blunt tip architecture distributes mechanical traction evenly across skin margins, sub-dermal tissues, and small fascial fields without causing localized trauma, skin tearing, or ischemic necrosis along the incision borders. Measuring a compact 4.0 inches in total length (10.2 cm structural footprint), this tool maximizes visual access within cramped surgical fields. Forged from high-tensile, passivated surgical stainless steel with a glare-reducing matte finish, this mechanical asset contains no moving electrical modules and is fully calibrated to withstand automated washer debridement and strict dynamic steam autoclave sterilization cycles inside central sterile supply departments (CSSD).
