Lockhart Mummery Fistula Director No.3 90

Clinical Application

Designed for anorectal procedures, this fistula director is used to identify, probe and delineate fistula-in-ano and sinus tracts. It provides controlled guidance when passing sutures or setons through established tracts and helps the surgeon avoid creating false passages during exploration. The instrument is suited to colorectal and proctologic procedures performed in operating rooms, ambulatory surgery centers and clinic settings.

Design & Configuration

The 90° angulation of the shaft facilitates access to lateral and posterior tracts that are difficult to reach with straight probes, allowing alignment of the tool with tract direction while maintaining a comfortable hand position. The tapered shaft eases atraumatic entry into narrow tracks, and the blunt, rounded tip protects against inadvertent tissue perforation while providing clear tactile feedback to the operator. The No.3 pattern represents a commonly used, mid-range configuration appropriate for most adult anorectal tracts.
