Abstract
635,391. Surgical knives. STEELE, W. E. Feb. 16, 1948, No. 4428. Convention date, June 4, 1946. [Class 81 (ii)] [Also in Group XXIII] The detachable blade of a scalpel has a centrally placed aperture which engages over a headed pin projecting laterally from the handle and the handle has restraining means engaging the butt end of the blade to prevent sideways or lengthwise movement thereof. In one form the blade 1, having a cutting edge 10, has a rectangular slot which, when set transversely to the handle, passes over the correspondingly shaped head of a pin 21 attached to an extension 20 of the handle 2. The blade is then turned about the pin until its end 12 rides up a chamfered surface 24 and snaps into a recess 22. The face of the handle extension against which the blade rests is slightly concave, so that the blade is maintained bent and so urged into the recess and, at the same time, positively pressed outwards against the head of the pin. The handle extension 20 is made narrower than the handle itself, over the greater part of its length, to enable the blade to be gripped when it is to be renewed. Other shapes of pin and slot may be employed, and attachment of the blade may be done by longitudinal instead of rotational movement.
