The 6½″ Lockhart Mummery Fistula Probe – Straight #1 is a specialized surgical instrument designed for the precise exploration and identification of fistulous tracts during anorectal and general surgical procedures. It is commonly used by colorectal surgeons and general surgeons to determine the direction, depth, and continuity of fistulas while preserving surrounding tissue integrity.
Measuring 6½ inches in length, this probe provides an excellent balance of reach and maneuverability. The Straight #1 configuration is ideal for examining superficial and relatively direct fistulous pathways, allowing surgeons to navigate tracts with precision and confidence. Its slender shaft and smooth contours facilitate atraumatic insertion, reducing the risk of creating false passages during examination.
The probe features a rounded, blunt tip specifically designed to follow the natural course of a fistula tract without unnecessarily damaging delicate tissues. This atraumatic design enhances procedural safety and assists in accurate diagnosis before definitive surgical treatment, such as fistulotomy or fistulectomy.
Manufactured from premium surgical-grade stainless steel, the 6½″ Lockhart Mummery Fistula Probe – Straight #1 provides outstanding durability, corrosion resistance, and long-lasting performance. The seamless one-piece construction ensures structural integrity while eliminating joints or seams where contaminants could accumulate. This robust design supports reliable performance throughout repeated clinical use.
Its ergonomic design offers excellent tactile feedback, enabling surgeons to detect changes in tract direction or resistance during exploration. The balanced construction improves handling precision and reduces hand fatigue during prolonged diagnostic or operative procedures.
The instrument features a mirror-polished finish that enhances corrosion resistance and creates a smooth, non-porous surface for efficient cleaning and sterilization. It is fully compatible with standard steam autoclave sterilization, making it a dependable reusable instrument for hospitals, surgical centers, and specialty colorectal practices.
The 6½″ Lockhart Mummery Fistula Probe – Straight #1 is widely used during fistula assessment, anorectal surgery, colorectal procedures, abscess evaluation, and other surgical interventions involving sinus or fistulous tracts. Its precision craftsmanship and atraumatic design make it an essential component of proctology and general surgery instrument sets.
Engineered to meet the rigorous demands of modern surgical practice, this instrument delivers the precision, reliability, and durability required for accurate fistula exploration and effective surgical planning.
