Abstract: A fine surgical instrument tip-cleaning device including a box-like cleaning unit that provides an outer abrasive cleaning surface and internal cleaning surfaces. The internal structure of the device consists of a transverse abrasive cleaning strut, which can be straddled by instruments such as forceps or bipolar cautery tips. The sidewalls of the cleaning box also contain abrasive cleaning lateral surfaces, which approximate the central cleaning strut. The lateral surfaces have a springiness, which permits the entrance of instrument tips into the box while maintaining constant contact of the abrasive cleaning surfaces against the instrument. In this fashion, effective removal of debris, coagulate and other substances are possible from surgical instruments even from the internal surfaces of forceps-type instruments. Easy introduction into the cleaning unit and back and forth motion of an instrument provides effective cleaning of the latter.
