Abstract

761,031. Polishing surgical catgut. ETHICON, Inc. Nov. 16, 1954 [Nov. 16, 1953]. No. 33177/54. Class 60 Apparatus for polishing surgical catgut to uniform gauge and circular crosssection comprises a grinding wheel 12, a regulating wheel 14, and a work support 15; the catgut strand 26 is held firmly in contact with the support 15 as it passes through the grindirig throat by liquid delivered from an adjustable nozzle 24 positioned above the throat. The liquid may be water, lard oil or a kerosene fraction of hydrocarbon oil and serves also to cool the catgut and wash away debris. The regulating wheel 14 is set at an angle with respect to the grinding wheel 12 so as to feed the strand through the grinding throat; the strand may be propelled through the throat by means of an additional push and pull operation, e.g. a hydraulic injector and pneumatic ejector. Specifications 550,850 and 550,859 are referred to.
