Abstract

A surgical instrument is provided including a handle portion and a body portion extending distally from the handle portion and defining a longitudinal axis. The surgical instrument also includes a grasper disposed at a distal end of the body portion, the grasper including an ultraviolet (UV) light mechanism for performing UV tacking of an implant. The implant is positioned between the first and second jaw members of the grasper: (i) to be placed at a surgical site and (ii) to be exposed by a UV light emitted from the UV light mechanism such that the UV tacking of the implant to the surgical site is performed.

First claim

The invention claimed is:

1. A method of tacking a mesh to a surgical site, the method comprising:
introducing a surgical instrument to the surgical site, the surgical instrument having an end effector disposed at a distal end thereof;
introducing the mesh to the surgical site, the mesh having a polymeric coating activatable by UV light;
positioning the mesh at a desired location at the surgical site;
manipulating the mesh using grasping portions of the end effector; and
selectively applying UV light with a first amount of energy to the mesh in a known location by a plurality of UV mechanisms positioned on surfaces of the grasping portions of the end effector to tack the mesh to tissue,
wherein each UV mechanism of the plurality of UV mechanisms is a discrete component and capable of emitting UV light.

2. The method according to claim 1 , wherein selectively applying the UV light to the mesh includes the surfaces of the grasping portions of the end effector adapted to contact one of tissue or mesh.

3. The method according to claim 2 , wherein manipulating the mesh includes positioning the mesh between the surfaces of the grasping portions of the end effector.

4. The method according to claim 1 , further including selectively applying UV light to the mesh by a second plurality of UV mechanisms positioned on second surfaces of the grasping portions of the end effector to tack the mesh to tissue, wherein the second surfaces are separate from the first surfaces and wherein each UV mechanism of the second plurality of UV mechanisms is a discrete component and capable of emitting UV light.

5. The method according to claim 4 , further including loosening the known location of the mesh from the first tissue location and repositioning the known location of the mesh to a tissue location other than the first tissue location.

6. The method according to claim 5 , further including selectively applying UV light to the mesh with a second amount of energy in a location other than the known location to tack the mesh to a second tissue location subsequent to repositioning the mesh.

7. The method according to claim 6 , wherein selectively applying UV light to the mesh with a second amount of energy includes applying an amount of energy that is greater than the amount of energy applied with the first amount of energy.

8. The method according to claim 1 , wherein selectively applying UV light to the mesh includes applying UV light emitted directly on one or more intra-pore films disposed on a portion of the mesh, the one or more intra-port films being positioned between the grasping portions of the end effector.

9. The method according to claim 1 , wherein selectively applying UV light to the mesh includes applying UV light emitted directly on one or more tack regions having visual location designations, the one or more tack regions being disposed on a portion of the mesh and positioned between the grasping portions of the end effector.

10. The method according to claim 1 , wherein selectively applying UV light to the mesh includes applying UV light emitted directly on one or more tack regions that are visually altered by the UV light, the one or more tack regions being disposed on a portion of the mesh and positioned between the grasping portions of the end effector.

11. The method according to claim 1 , further including monitoring the UV light emitted from the first and second pluralities of UV mechanisms using at least one sensor operably coupled to the surgical instrument.

12. The method according to claim 1 , wherein selectively applying UV light to the mesh includes selectively actuating a trigger mechanism positioned on a handle portion of the surgical instrument.

13. The method according to claim 1 , wherein selectively applying UV light to the mesh includes selectively applying UV light directly on the mesh using a control mechanism operably coupled to the first and second pluralities of UV mechanisms.

14. A method of tacking a mesh to a surgical site, the method comprising:
introducing a surgical instrument to the surgical site, the surgical instrument having an end effector disposed at a distal end thereof;
introducing the mesh to the surgical site, the mesh having a polymeric coating activatable by UV light;
positioning the mesh at a desired location at the surgical site;
manipulating the mesh using grasping portions of the end effector;
selectively applying UV light to a first area of the mesh by a first plurality of UV mechanisms positioned on first surfaces of the grasping portions of the end effector, wherein the first area of the mesh is in contact with the first surfaces; and
selectively applying UV light to a second area of the mesh by a second plurality of UV mechanisms positioned on second surfaces of the grasping portions of the end effector, wherein the second area of the mesh is separate from the first area,
wherein each UV mechanism of the first and second pluralities of UV mechanisms is a discrete component and capable of emitting UV light.

15. A method of tacking a mesh to a surgical site, the method comprising:
introducing a surgical instrument to the surgical site, the surgical instrument having an end effector disposed at a distal end thereof;
introducing the mesh to the surgical site, the mesh having a polymeric coating activatable by UV light;
positioning the mesh at a desired location at the surgical site;
manipulating the mesh using grasping portions of the end effector; and
selectively applying UV light to the mesh directly on one or more tack regions having visual location designations by a plurality of UV mechanisms positioned on surfaces of the grasping portions of the end effector to tack the mesh to tissue, the one or more tack regions being disposed on a portion of the mesh and positioned between the grasping portions of the end effector,
wherein each UV mechanism of the plurality of UV mechanisms is a discrete component and capable of emitting UV light.
