Abstract
In a scalpel having a disposable blade and a handle for retaining the blade, the disposable blade is provided on its rear end portion with at least one tongue piece which can be held with a tool such as a needle holder or forceps. The replacement of the blade with another can be easily and promptly carried out while holding the tongue piece with the tool even in the midst of the surgical operation, so that the blades of various types different in shape can be properly used for each purpose.
