A scalpel blade remover in which the blade is clamped against a fixed block by manipulating a lever to cause a movable block to move toward the fixed block. The movable block is preferably made of resilient material and all other elements of the structure are made of metal such as stainless steel, all components being autoclavable. A tab is provided on the movable block to engage an end of the blade and move that end relative to the body of the blade and the scalpel handle to disengage the blade from the handle. The blocks are mounted upon a supporting surface, beneath which a sterile disposable box may be disposed. The supporting surface is slotted in a plane which includes the area of clamping of the scalpel blade between the fixed and movable blocks. The movable block may also be provided with a guide portion to ensure the clamping action, and the movable block may be provided with a relieved or cut-off end permitting a scalpel blade to be disengaged from the scalpel handle.
A device for removing a scalpel blade from a handle comprising a support base, a fixed block mounted on said base, a movable block also mounted on said base, at least one of said blocks being made of resilient material, means for moving said movable block toward and away from said fixed block, movement toward said fixed block being effective to clamp said blade between confronting surfaces of said fixed and movable blocks, and means formed adjacent one end of one of said blocks to contact an end of said blade and disengage said blade from said handle, movement of said movable block away from said fixed block permitting separation of said handle from said blade.
A device for removing a scalpel blade from a handle comprising a support base having a generally rectangular cross-section, an open inner volume, and a flat upper surface, a fixed block mounted on said surface, a movable block of resilient material slidably mounted on said surface, spring means normally urging said movable block away from said fixed block, a lever having a cam surface bearing upon said movable block and operative to move said movable block toward and away from said fixed block, manipulation of said lever in one direction causing said movable block to clamp said blade against said fixed block and permitting separation of said handle from said blade, a slot being formed in said upper surface in alignment with the plane of clamping of said blade, releasing of said lever in a direction opposite to said one direction permitting said spring means to cause movement of said movable block away from said fixed block and declamping of said blade, said blade then dropping through said slot.
