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.

Claims

1. A device for removing a blade having an opening therethrough from a tang of a blade handle, said tang extending upwardly through said opening to mount said blade on said tang comprising:

two members spaced to form a channel, said members having distal and proximal ends and upper and lower portions, each of said upper portions having a blade receiving surface mutually spaced a distance greater than the width of the tang and less than the width of the blade;

the proximal ends of each of said upper portions having an upwardly extending projection to form a shoulder for abutting the heel of the blade;

each of said members having a camming surface between its proximal upper portion and proximal lower portion, said camming surface directing the handle between said lower portions as the handle is pushed distally while the blade rests against said blade receiving surfaces to pry the heel of the blade over the tang;

the proximal ends of said lower portion being mutually spaced a distance sufficient to permit said handle to be pushed distally between said members until the heel of said blade abuts said shoulders, said shoulders preventing said blade from moving with the handle as its is removed from the blade by pulling it longitudinally relative to the blade.

2. A device for removing a surgical blade from a tang of a blade handle comprising:

two spaced members each having blade receiving surfaces, said members being complimentary contoured to form a channel having a narrow portion and a wide portion;

said members having means for holding said blade to prevent the blade from moving with the handle when the handle is removed from the device;

said narrow portion of the channel being wider than the tang but narrower than the blade to permit the blade to rest against said blade receiving surfaces and to permit the blade to be pried over the tang when the handle is moved away from said surfaces;

said wide portion of the channel sized to permit the handle to enter the channel between the members sufficiently that the heel of the blade can engage said holding means.

3. A device for removing a blade having an opening therethrough from a tang of a blade handle comprising:

two members having distal and proximal ends spaced to form a channel, said members having upper surfaces which are suitable for supporting a surgical blade, each of said surfaces having means for abutting a heel of said blade;

said channel having first and second portions, said first portion being located between the distal ends of said members and of a width greater than the width of the tang but less than the width of the blade, said second portion being located between the proximal ends of said members and of a width sufficient to permit the handle to be pushed distally between the members beyond said abutting means so that when the handle is removed from the device, the abutting means abuts the heel of the blade to prevent the blade from moving with the handle.

4. A device for removing a blade from a tang of a blade handle comprising:

two members each having proximal and distal ends spaced to form a channel;

said members having means for supporting the blade spaced less than the width of the blade and greater than the width of the tang;

said members having means for holding the blade;

each member having a camming surface located between an upper and lower proximal end which is traversed by the handle as it is pushed toward the distal ends of the members while the blade rests against the blade supporting means to release the heel of the blade from the tang;

said members being spaced between their lower proximal ends a distance sufficient to permit the handle to be pushed between the members until the blade engages said holding means.

5. A device for removing a blade from a tang of a blade handle comprising:

two spaced members each having blade receiving surfaces, said surfaces being spaced a distance greater than the tang but less than the width of the blade, to permit the blade to rest against the surfaces and be pried over the tang when the handle is moved away from the surfaces;

each member having means for holding the heel of the blade when the heel is pried over the tang;

a portion of the members being spaced a distance sufficient to permit the handle to be pushed far enough distally that the heel of the blade engages the holding means to prevent the blade from moving with the handle when the handle is removed from the device.
