Abstract

A coated surgical fastener is provided for an easy visualization within tissue. The coated surgical fastener includes a core and a relatively non-reflective coating applied about the core. There is also disclosed an illuminated staple cartridge for use with a surgical stapling device having a light source. The illuminated staple cartridge includes a transparent insert and a relatively nontransparent U-shaped outer channel at least partially surrounding the transparent insert. Windows formed in sides of the U-shaped outer channel allow defined amounts of light to project from the sides of the illuminated staple cartridge.

Claims

1. A surgical fastener comprising:

a core material having at least one tissue penetrating tip; and

a non-reflective coating applied to at least a portion of the core material, the non-reflective coating emitting visible rays.

2. The surgical fastener as recited in claim 1, wherein the non-reflective coating has a molecular fluorescence.

3. The surgical fastener as recited in claim 1, wherein the non-reflective coating has a molecular phosphorescence.

4. The surgical fastener as recited in claim 1, wherein the non-reflective coating is chemiluminescent.

5. The surgical fastener as recited in claim 1, wherein the at least one tissue penetrating tip of the fastener is uncoated.

6. The surgical fastener as recited in claim 1, wherein the core material is formed into a backspan and a leg extending from each end of the backspan.

7. The surgical fastener as recited in claim 6, wherein each leg extending from the backspan terminates in the tissue penetrating tip.

8. The surgical fastener as recited in claim 1, wherein the core material is formed into a helical coil terminating in a tissue penetrating tip at one end and a compressed coil at an opposing end.

9. A surgical stapling device comprising;

a handle;

an elongate tubular member extending distally from the handle;

an illuminated staple containing cartridge mounted on a distal end of the elongate tubular member; and

a light source associated with the distal end of the elongate tubular member, such that light emitted from the light source is transmitted to the illuminated staple containing cartridge, wherein the transmitted light is emitted by the illuminated staple containing cartridge.

10. The surgical stapling device as recited in claim 9, wherein the illuminated staple containing cartridge includes a U-shaped outer channel and a transparent staple containing insert.

11. The surgical stapling device as recited in claim 10, wherein a portion of the transmitted light passes through the transparent staple containing insert.

12. The surgical stapling device as recited in claim 9, wherein the U-shaped outer channel includes a plurality of windows.

13. The surgical stapling device as recited in claim 12, wherein a portion of the transmitted light passes through the plurality of windows.
