The instrument for removing exchangeable blades from surgical scalpes consists of two arms /1 and 2/ connected with each other and forming approximately the shape of the letter "U" or "V". The end of the arm /1/ is provided with two protrusions /3 and 4/ and with the catch disposed at a distance therefrom /5/, the end of the arm /2/ being provided with two similar protrusions /6 and 7/. The protrusions /3 and 4, and 6 and 7/ of both arms /1 and 2/ are displaced against each other by such a distance that under the influence of the arms /1 and 2/ by means of the protrusions /3, 4, 6, 7/ onto the blade /11/ mounted on the scalped /10/ it follows a bending of the dull-edged end of the blade /11/ above the upper plane of the lock /9/ of the scalpel /10/, and catching against the catch /5/. The blade /11/ bent in this way acts onto the instrument with a tangential force and gets put out from the lock /9/ of the scalpel /10/. |
