  • Patent number: 9717521
    Abstract: A knife (10) has a handle (15) with a mount (16) for affixing a removable blade (11). A concave surface (17) of the mount supports an elongate protrusion (18) for engaging a complementary slot (12) in the blade and reaches a landing (20) rearward of the tip that is exposed when the blade is mounted on the handle with a surface of the blade being completely supported by the concave surface. A channel (25) in the landing is dimensioned such that a rearmost part (26) thereof remains exposed when the blade is mounted on the handle. The blade is removed by inserting a curved lever (30) into the channel underneath a rearmost part of the blade and swiveling the lever so as to disengage the blade from the elongate protrusion.

  • Patent number: 9504487
    Abstract: A scalpel blade remover comprises a housing, and a planar member mounted in the housing with a longitudinal slot therein. A slider is adapted to slide along the planar member, and has an opening for receiving a portion of a tang therein. The slider is movable along the planar member when pressed by the tang being inserted into the opening and moved along the slot, with the blade being located under the slider. Movement of the slider along the planar member causes the planar member to separate the rear end of the blade from the tang. A stop formation on the planar member engages the rear end of the blade after it has been separated from the tang and prevents the blade being withdrawn along the member. Upon withdrawal of the tang, the blade is stripped from the tang.

  • Patent number: 6605100
    Abstract: A modified scalpel and blade exchanging apparatus and method whereby insertion of the scalpel blade (106) end into the apparatus and turning of the scalpel handle (111) causes the dull or spent blade to be exchanged with a new blade (130) on the scalpel (101) in a few seconds. The quick exchange is accomplished by a cam system (183, 184) that opens and closes the jaws or fingers (104, 105) that retain the blade on the scalpel and a dispenser (119) that positions the new blade in the open jaws or fingers just prior to closure. The new invention solves the problem of detaching and attaching scalpel blades in a matter of seconds without danger to the user. With a mere twist of the wrist, the user detaches the dull blade and attaches the new blade, the dull blade dropping into a sharps container (107) upon detachment.

  • Patent number: 5938027
    Abstract: The handle has a blade mounting portion with a raised boss forming a slot. The blade has a boss receiving recess with a portion defined by an edge. The cartridge removeably retains the blade. It has an opening into which the blade mounting portion of the handle can be inserted. A normally arcuate spring is mounted in cantilever fashion within the enclosure. The tip of the blade abuts a stop surface proximate the unattached end of the spring. In its arcuate state, the spring retains the blade in a position where the edge of the blade can enter the slot in the handle. As the blade is moved by insertion of the handle, against the urging of the spring, the spring straightens allowing the blade to assume a position where the boss can be fully seated within the recess, mounting the blade on the handle. The blade is then removed from the cartridge by withdrawing the handle. After use, the blade is reinserted into the cartridge.

  • Patent number: 5875533
    Abstract: A scalpel blade remover removes a blade from the tang of a scalpel. The scalpel is inserted in, and withdrawn from, the blade remover along the same substantially straight-line path. The blade remover has a rocker block which pivots about an axis transverse to the insertion path. When the scalpel is inserted into the blade remover, its tang pushes against a contact surface of the rocker block, causing the rocker block to pivot. A pair of legs at the other end of the rocker block apply a transverse force to the heel of the blade on either side of the tang, thereby lifting the heel of the blade off the tang. When the scalpel has been inserted far enough, a pawl drops behind the heel of the blade. The pawl strips the blade from the tang when the scalpel handle is removed. The blade remover is typically mounted in the lid of a sharps container.

  • Patent number: 5449068
    Abstract: Apparatus for safely and conveniently removing a blade from a surgical scalpel, and for disposing of used blades. The preferred embodiment includes an aperture through which the blade may be inserted into a container. The aperture is defined by parallel guide walls. A first and second shoulder project from one guide wall, and a third shoulder projects from the other guide wall. An angled blade deflector is disposed in the interior of the container, behind the aperture. Insertion of the scalpel blade into the aperture and against the angled blade deflector pushes the blade against the first and second shoulders, which causes the blade to deform and separate slightly from the handle and to engage the third shoulder. This third shoulder holds the rear of the blade within the aperture, so that manual withdrawal of the handle from the aperture detaches the blade from the handle, leaving the detached blade within the container for easy disposal.

  • Patent number: 4730376
    Abstract: A blade removal apparatus for a changeable blade scalpel in which a blade is removably mounted on a scalpel handle by fitting a mounting hole formed in the blade over a blade mounting part having a narrow width provided on the tip end of the scalpel handle. The blade removal apparatus has a box part having an open top and a side wall and an acceptor part projecting laterally from the upper part of the side wall, and a cover part closing the open top and having a visored part extending over the acceptor part. A guide edge on the acceptor part defines a lower gap tapered so as to become narrower as it extends to the inside of the box part and into which blade mounting parts of changeable blade scalpels of various types can be inserted. The cover part has a stopping stepped part defining an upper gap between the lower surface of the visored part and the guide edge and into which upper gap a blade on a scalpel is insertable.

  • Patent number: 4395807
    Abstract: A surgical blade remover is disclosed wherein a surgical blade is easily and effectively removed from the tang of a handle. The device is provided with two members which are spaced to form a channel sized to permit the tang to be positioned between them while the blade rests on the upper surfaces of the members. The channel between the members at their lower portions widens to permit the handle to enter the channel sufficiently that the heel of the blade can abut a projection which extends upward from each surface of the members. The handle enters this widened lower portion of the channel while the blade rests against the upper surfaces of the members thereby releasing the heel of the blade from the tang. The blade can then be removed from the handle by pulling the handle out of the channel because the projections prevent the blade from moving with the handle.

  • Patent number: 4386457
    Abstract: A device for removing a surgical blade from a scalpel handle includes a housing having an aperture. A surgical blade attached to a boss of the handle is inserted into the aperture. The boss is pressed downward into a narrow notch in the wall surrounding the aperture so that the edges of the notch engage the shank of the blade, preventing it from being moved into the notch with the boss and separating the shank of the blade from the rear portion of the boss. Two spring loaded pinch members extend from within the aperture so that they can be pinched together by the fingers of a user and engage the opposed edges of the blade, preventing it from moving as the handle is pulled away from the blade, causing the boss to become disengaged from the blade and withdrawn from an elongated hole in the shank of the blade. When the pinch members are released, the blade falls to the bottom of the interior of the housing, which serves as a receptacle.

  • Patent number: 4344532
    Abstract: A surgical blade remover is disclosed having an essentially wedge-shaped support member which tapers from its front side to its back side. The support has one or more mutually parallel latitudinal slots open at one end and along their length extending from the front side of the support into its interior. The slots are sized to receive the tang of the blade holder while preventing the blade itself from passing therethrough. The surface of the support member bordering each slot is covered with an adhesive which holds the blade in place as the blade holder is pivoted downward in the slot away from the blade. When the hilt of the blade becomes detached from the holder, as a result of this pivoting action, the holder is withdrawn from the slot. The blade remains affixed to the adhesive on the support and is retained for its disposal.
