Abstract

The present disclosure is directed towards a medical instrument. The medical instrument includes a housing and an end effector assembly operably connected to the housing. The end effector assembly includes first and second jaw members each having a tissue contacting surface, at least one of the first and second jaw members movable between a first, spaced-apart position and a second proximate position, wherein in the second position, the jaw members cooperate to define a cavity configured to receive tissue between the jaw members. The end effector also includes at least one light-emitting element coupled to at least one of the first and second jaw members, the at least one light-emitting element adapted to deliver light energy to tissue grasped between the first and second jaw members to treat the tissue.

Claims (28)

1. A medical instrument, comprising:

a housing; and

an end effector assembly operably connected to the housing, the end effector assembly including:

first and second jaw members each having a tissue contacting surface, at least one of the first and second jaw members movable between a first, spaced-apart position and a second position for approximating tissue, at least one of the first and second jaw members including a groove defined therein having a reflective surface; and

at least one light-emitting element disposed within the groove, the at least one light-emitting element adapted to deliver light energy to tissue grasped between the first and second jaw members.

2. The medical instrument according to claim 1 , wherein the at least one light-emitting element is configured to emit light directly into the tissue without an intervening optical assembly.

3. The medical instrument according to claim 1 , further comprising an optical assembly coupled to the at least one light-emitting element, the optical assembly configured to convey light emitted from the at least one light-emitting element to the tissue and to illuminate the tissue with a desired illumination pattern.

4. The medical instrument according to claim 3 , wherein the optical assembly includes at least one of an optical fiber, a refractive element, a reflective element, a diffracting element, and combinations thereof.

5. The medical instrument according to claim 4 , wherein the optical assembly is disposed within at least one of the first jaw member or the second jaw member.

6. The medical instrument according to claim 5 , wherein the optical assembly is configured to translate within at least one of the first jaw member or the second jaw member along a longitudinal axis defined by at least one of the first jaw member or the second jaw member.

7. The medical instrument according to claim 1 , wherein the at least one light-emitting element is selected from the group consisting of a light-emitting diode, a laser, and combinations thereof.

8. The medical instrument according to claim 1 , wherein at least one of the tissue contacting surfaces includes an absorbent element configured to absorb light energy emitted from the at least one light-emitting element thereby heating at least one of a portion of the tissue, the first jaw member, the second jaw member, and combinations thereof.

9. The medical instrument according to claim 1 , wherein at least one of the tissue contacting surfaces includes a reflective element configured to reflect light passing through the tissue.

10. The medical instrument according to claim 1 , wherein the at least one light-emitting element is disposed within the housing.

11. The medical instrument according to claim 1 , wherein the at least one light-emitting element is configured to translate within at least one of the first jaw member or the second jaw member along a longitudinal axis at least one of the first jaw member or the second jaw member.

12. The medical instrument according to claim 1 , further comprising at least one light-detecting element configured to measure at least one property of the light.

13. The medical instrument according to claim 11 , further comprising a controller configured to determine whether a desired tissue effect has been achieved based on the measured at least one property of the light.

14. A system for treating tissue, comprising:

a medical instrument comprising:

a housing; and

an end effector assembly operably connected to the housing, the end effector assembly including:

first and second jaw members each having a tissue contacting surface, at least one of the first and second jaw members movable between a first, spaced-apart position and a second position for approximating tissue, at least one of the first and second jaw members including a groove defined therein having a reflective surface;

at least one light-emitting element disposed within the groove, the at least one light-emitting element adapted to deliver light energy to tissue grasped between the first and second jaw members;

at least one light-detecting element configured to measure at least one property of the light energy passing through the tissue; and

a controller coupled to the at least one light-detecting element and the at least one light-emitting element, the controller configured to control the at least one light-emitting element based on the at least one measured property of the light energy passing through the tissue.

15. The system according to claim 14 , wherein at least one of the at least one light-emitting element and the controller are disposed within the housing.

16. The system according to claim 14 , wherein at least one of the tissue contacting surfaces includes an absorbent coating disposed thereon, the absorbent coating configured to absorb light energy emitted from the at least one light-emitting element to heat at least a portion of at least one of the first and second jaw members.

17. The medical instrument according to claim 14 , wherein at least one of the tissue contacting surfaces includes a reflective coating disposed thereon, the reflective coating configured to reflect light energy emitted from the at least one light-emitting element.
