Abstract

A suture needle container includes a receptacle having a proximal end with an opening and a closed distal end. A hollow mandrel is disposed inside the receptacle. The mandrel projects from the closed distal end toward the opening at the proximal end of the receptacle. The mandrel includes a tubular wall having a proximal end aligned with the proximal end of the receptacle and a distal end connected with the closed distal end of the receptacle. An elongated slot is formed in the tubular wall. A suture needle is disposed within the elongated slot. A suture is secured to the proximal end of the suture needle and wrapped around the hollow mandrel. A cover closes the opening at the proximal end of the receptacle for sealing the suture needle and the suture inside the receptacle for maintaining a sterile environment inside the receptacle.

First claim

What is claimed is:

1. A suture needle container comprising:
a receptacle having a proximal end with an opening and a distal end that is closed by an end wall;
a mandrel located inside said receptacle, said mandrel having a tubular wall that projects from said end wall of said receptacle toward the opening at the proximal end of said receptacle, wherein said tubular wall defines a needle driver guide channel having a height and a width, said needle driver guide channel extending from a proximal end of said tubular wall to a distal end of said tubular wall;
an elongated slot formed in said tubular wall that extends from the proximal end of said tubular wall toward said end wall of said receptacle;
a suture needle disposed within said elongated slot, wherein said suture needle has a distal end disposed inside said tubular wall and a proximal end disposed outside said tubular wall;
a cover sealing the opening at the proximal end of said receptacle that maintains a sterile environment inside said receptacle.

2. The suture needle container as claimed in claim 1 , wherein said receptacle comprises a cylindrical outer wall that extends between the proximal and distal ends of said receptacle.

3. The suture needle container as claimed in claim 2 , wherein said cylindrical outer wall surrounds said mandrel and said tubular wall is centrally located inside said cylindrical outer wall.

4. The suture needle container as claimed in claim 1 , wherein the distal end of said tubular wall is connected with said end wall of said receptacle and the proximal end of said tubular wall is in substantial alignment with the proximal end of said receptacle.

5. The suture needle container as claimed in claim 1 , wherein said elongated slot is open at the proximal end of said tubular wall and said elongated slot has a closed end that is proximal to and spaced from said end wall of said receptacle.

6. The suture needle container as claimed in claim 5 , wherein said distal end of said suture needle comprises a tapered section that terminates at a tip that defines a distal-most end of said suture needle, and wherein said tip is located inside said tubular wall and said tapered section of said suture needle passes through said elongated slot.

7. The suture needle container as claimed in claim 6 , wherein a distal portion of said tapered section of said suture needle is disposed inside said tubular wall and a proximal portion of said suture needle is disposed outside said tubular wall and inside said receptacle.

8. The suture needle container as claimed in claim 1 , wherein said cover sealing the opening at the proximal end of said receptacle comprises a material selected from a group consisting of foil, polymers, plastics, high-density polyethylenes, and Tyvek.

9. A surgical system including the suture needle container as claimed in claim 1 , said surgical system comprising a needle driver including an elongated shaft having a distal end with a clamping assembly having lower and upper jaws moveable between an open position and a closed position, wherein said lower and upper jaws in the open position define an open jaw height that matches the height of said needle driver guide channel and said lower and upper jaws define a jaw width that matches the width of said needle driver guide channel.

10. The surgical system as claimed in claim 9 , wherein said needle driver guide channel has a floor located at a lower end of said needle driver guide channel, a ceiling located at an upper end of said needle driver guide channel, and opposing side walls that extend between said floor and said ceiling, wherein said elongated slot is formed in one of said opposing side walls, and wherein said floor has a surface that conforms to an underside of said elongated shaft of said needle driver.

11. The surgical system as claimed in claim 10 , wherein said elongated shaft has an outer diameter, and wherein said elongated slot is spaced away from said floor of said needle driver guide channel by a distance that is greater than ½ of the outer diameter of said elongated shaft of said needle driver.

12. The surgical system as claimed in claim 9 , wherein said lower jaw has a distal end and a top surface adapted to engage said distal portion of said tapered section of said suture needle disposed inside said tubular wall, wherein said top surface of said lower jaw has a length that is greater than a distance between said closed end of said elongated slot and said end wall of said receptacle for aligning said tip of said suture needle over said top surface of said lower jaw when the distal end of said lower jaw is abutted against said end wall of said receptacle.

13. A suture needle container comprising:
a receptacle having a proximal end with an opening and a closed distal end;
a hollow mandrel disposed inside said receptacle that projects from the closed distal end of said receptacle toward the opening at the proximal end of said receptacle, said hollow mandrel including a tubular wall having a proximal end aligned with the proximal end of said receptacle and a distal end connected with the closed distal end of said receptacle, wherein said tubular wall defines a needle driver guide channel having a height and a width, said needle driver guide channel extending from the proximal end of said tubular wall to the distal end of said tubular wall;
an elongated slot formed in said tubular wall that extends from the proximal end of said tubular wall to a location that is proximal to and spaced from the closed distal end of said receptacle;
a suture needle disposed within said elongated slot, wherein said suture needle has a distal end with a tip that is disposed inside said tubular wall and a proximal end disposed outside said tubular wall;
a suture secured to said proximal end of said suture needle and wrapped around said hollow mandrel;
a cover closing the opening at the proximal end of said receptacle for sealing said suture needle and said suture inside said receptacle and maintaining a sterile environment inside said receptacle.

14. The suture needle container as claimed in claim 13 , wherein said distal end of said suture needle comprises a tapered section that terminates at said tip that defines a distal-most end of said suture needle, and wherein said tip is located inside said tubular wall and said tapered section of said suture needle passes through said elongated slot.

15. A surgical system including the suture needle container as claimed in claim 13 , said surgical system comprising a needle driver including an elongated shaft having a distal end with a clamping assembly having lower and upper jaws moveable between an open position and a closed position, wherein said lower and upper jaws in the open position define an open jaw height that matches the height of said needle driver guide channel and said lower and upper jaws define a jaw width that matches the width of said needle driver guide channel.

16. The surgical system as claimed in claim 15 , wherein said needle driver guide channel has a floor located at a lower end of said needle driver guide channel, a ceiling located at an upper end of said needle driver guide channel, and opposing side walls that extend between said floor and said ceiling, wherein said elongated slot is formed in one of said opposing side walls and is closer to said floor than said ceiling of said needle driver guide channel.

17. The surgical system as claimed in claim 16 , wherein said elongated shaft of said needle driver has an outer diameter, and wherein said elongated slot is spaced away from said floor o
