Abstract
Abstract A surgical staple remover comprises first and second handle elements pivotally connected to each other. The front portion of the first handle element terminates in a pair of outwardly extending anvil sections having outside surfaces that diverge away from each other in the front to rear direction so that different size staples may be received thereon until the staples contact the diverging outside surfaces thereof. A blade section on the front portion of the second handle element is constructed and arranged for movement toward and away from the anvil sections, and the blade section has a lower concavely curved staple engaging edge. The curved edge engages a staple on the anvil sections with a downward and rearward force to produce a U-shaped bend in the crown of the staple to thereby facilitate its removal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
200 words
A surgical staple remover comprising a first handle element having a rear portion and a front portion terminating in a pair of outwardly extending anvil sections, portions of which are separated from one another by a slotted opening, the anvil sections having outside surfaces that diverge away from each other in a front to rear direction whereby different size staples may be received thereon until the staples contact the diverging outside surfaces thereof, a second handle element having a rear portion and a front portion provided with a blade section constructed and arranged for movement toward and away from the anvil sections and into and out of the slotted opening therebetween, the blade section having a lower concavely curved staple engaging edge, and means pivotally connecting together the first and second handle elements whereby the concavely curved edge of the blade section moves toward the anvil sections and through the slotted opening when the rear portions of the handle elements are moved toward each other to cause the curved edge to engage a staple on the anvil sections with a downward and rearward force and thereby crimp the staple without forward or rearward movement of the staple on the anvils.
Claim 2
Dependent Claim
200 words
A surgical staple remover comprising a first handle element having a rear portion and a front portion terminating in a pair of outwardly extending anvil sections, portions of which are separated from one another by a slotted opening, the anvil sections having outside surfaces that diverge away from each other in a front to rear direction whereby different size staples may be received thereon until the staples contact the diverging outside surfaces thereof, a second handle element having a rear portion and a front portion provided with a blade section constructed and arranged for movement toward and away from the anvil sections and into and out of the slotted opening therebetween, the blade section having a lower concavely curved staple engaging edge, and means pivotally connecting together the first and second handle elements whereby the concavely curved edge of the blade section moves toward the anvil sections and through the slotted opening when the rear portions of the handle elements are moved toward each other to cause the curved edge to engage a staple on the anvil sections with a downward and rearward force and thereby crimp the staple without forward or rearward movement of the staple on the anvils.
Claim 3
Dependent Claim
36 words
A surgical staple remover as in claim 1 wherein the outwardly extending anvil sections are disposed in a plane and the pivot means is rearward of the anvil sections but relatively close to the plane thereof.
Claim 4
Dependent Claim
27 words
A surgical staple remover as in claim 1 wherein the anvil sections contact each other forward of the slotted opening to thereby form a closed front tip.
Claim 5
Dependent Claim
42 words
A surgical staple remover as in claim 1 including upstanding wall means on the first handle element immediately rearward of the anvil sections and forward of the pivot means to thereby limit rearward movement of a staple positioned on the anvil sections.
Claim 6
Dependent Claim
27 words
A surgical staple remover as in claim 1 wherein the rear portion of each of the first and second handle elements is provided with a finger-receiving ring.
Claim 7
Dependent Claim
