Abstract

The surgical saw has a reciprocating mechanism driven by a motor and coupled on the outside detachably by a clamp to one end of an oblong saw blade. It has an oblong housing with the reciprocating mechanism (23-27) in one end and a compressed-air motor (16) in the other. The rotary output shaft (19) of the motor is in line with and directly coupled to the input shaft (20) of the mechanism. The clamp gripping the blade pivots on an eccentric output member (27) of the mechanism, and which drives it to the fro in the lengthwise direction of the housing. The reciprocating mechanism can also have a second rotary and transverse shaft (25) with a level gear (24) meshing with one n23) on the input shaft.
