Claims15
An improved medical staple of the type for being held by a staple holder as it is driven into and/or removed from bone structure and including a first leg member having upper and lower ends, a second leg member having upper and lower ends, a bridge member for joining said first and second leg members to one another in a substantially parallel and spaced apart relationship, said bridge member having first and second ends for fixed attachment to said upper ends of said first and second leg members respectively, said bridge member having first and second sides, wherein said improvement comprises:
- groove means on said bridge member for receiving portions of said staple holder to allow said medical staple to be securely and positively held by said staple holder as said medical staple is driven into and/or removed from bone structure.
A medical staple means comprising, in combination:
- (a) a medical staple including a first leg member having upper and lower ends, a second leg member having upper and lower ends, and a bridge member for joining said first and second leg members to one another in a substantially parallel and spaced apart relationship, said bridge member having first and second ends for fixed attachment to said upper ends of said first and second leg members respectively, said bridge member having first and second sides, said first side of said bridge member having a groove therein, said second side of said bridge member having a groove therein;
- and
- (b) a medical staple holder for selectively engaging said bridge member of said medical staple to hold said medical staple, said medical staple holder including jaw means for selectively engaging said bridge member of said medical staple, said jaw means including ridge members for extending into said grooves in said bridge member of said medical staple when said jaw means is engaging said bridge member of said medical staple.
A medical staple means comprising, in combination:
- (a) a medical staple including a leg member having upper and lower ends, and a bridge member for fixed attachment to said upper end of said leg member, said bridge member having a groove therein;
- and
- (b) a medical staple holder selectively engaging said bridge member of said medical staple to hold said medical staple, said medical staple holder including a body means having a first end and a second end and having an aperture extending completely therethrough from said first end to said second end, said aperture being flared outwardly at said first end to form a cam surface, said medical staple holder including jaw means for selectively engaging said bridge member of said medical staple, said jaw means including two coacting jaw members, each of said jaw members including a mouth portion for gripping opposite sides of said bridge member of said medical staple and including a cam portion for coacting with said cam surface of said body means, at least one of said mouth portions of said jaw means including a ridge for extending into said groove in said bridge member of said medical staple when said mouth portions of said jaw members are in engagement with said bridge member of said medical staple, said medical staple holder including activating means for selectively causing said cam portion of said jaw means to engage said cam surface of said body means to cause said mouth portions of said jaw means to engage said bridge member of said medical staple.
A medical staple means comprising, in combination:
- (a) a medical staple including a leg member having upper and lower ends, and a bridge member for fixed attachment to said upper end of said leg member, said bridge member having grooves in the sides thereof;
- and
- (b) a medical staple holder for selectively engaging said bridge member of said medical staple to hold said medical staple, said medical staple holder including jaw means for selectively engaging said bridge member of said medical staple, said jaw means including ridge members for extending into said grooves in said bridge member of said medical staple when said jaw means is engaging said bridge member of said medical staple.
An improved medical staple holder of the type including a body means having a first end and a second end and having an aperture extending from said first end to said second end, said aperture being flared outwardly at said first end to form a cam surface;
- including jaw means for selectively engaging the bridge member of a medical staple, said jaw means including two coacting jaw members, each of said jaw members including a mouth portion for gripping opposite sides of the bridge member of the medical staple and including a cam portion for coacting with said cam surface of said body means;
- and including activating means for selectively causing said cam portions of said jaw means to engage said cam surface of said body means to cause said mouth portions of said jaw means to engage the bridge member of the medical staple, wherein the improvement comprises:
- ridge means on said mouth portion of each of said jaw members of said jaw means for extending into a groove in the sides of the bridge portion of the medical staple when said mouth portions of said jaw members are in engagement with the bridge member of the medical staple to allow the medical staple to be securely and positively held by said staple holder as the medical staple is driven into and/or removed from bone structure.
