The present invention relates to a blade remover that can safely and conveniently remove the blade from the handle of the scalpel used for medical and scientific experiments.

The scalpel is widely used in medical activities such as detaching or dissecting part of biological tissues or in various scientific experiments. However, the scalpel is shown in FIGS. 1 (a separate perspective view showing a conventional scalpel) and FIG. 2 (a diagram showing a handle and a blade joint band constituting the scalpel and a coupling structure of the blades in the order of attachment process between the blade and the blade joint band). As shown in the drawing, a disposable blade 20 and a handle 10 for detachably fixing the blade 20 are provided. In general, the blade 20 may be contaminated so that it may not be utilized in other biological tissues in the process of cutting or detaching a specific part of the biobulg tissue. Therefore, as shown, except for the handle 10, which is recyclable, the blade 20 may be detachably attached to the handle 10 so that the blade 20 may be immediately replaced with a new blade.

To this end, the handle 10 has a blade joint 30 for fixing the blade 20 is formed at one end. The blade joint 30 has a bar shape having a predetermined width and length, as shown, guide grooves 31 are formed on both sides of the front end, and the fitting protrusions 32 protruding to a predetermined height are provided on the upper surface. On the other hand, the blade 20 is formed so that the fitting hole 21 is engaged with the fitting projection 32 is formed so that it can be firmly engaged with the blade joint 30.
