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 (12)

1. An end effector assembly for use with a medical instrument, comprising:

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

a 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 to perform at least one of cutting or sealing the tissue.

2. The end effector assembly according to claim 1 , wherein the light-emitting element is configured to emit light directly into the tissue without an intervening optical assembly.

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

4. The end effector assembly according to claim 3 , wherein the optical assembly includes at least one of an optical fiber, a refractive element, a reflective element, or a diffracting element.

5. The end effector assembly 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 end effector assembly 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 end effector assembly according to claim 3 , wherein the light-emitting element is selected from the group consisting of a light-emitting diode, a laser, and combinations thereof.

8. The end effector assembly according to claim 3 , wherein at least one of the tissue contacting surfaces includes an absorbent element configured to absorb light energy emitted from the light-emitting element thereby heating at least one of the tissue, the first jaw member, or the second jaw member.

9. The end effector assembly according to claim 3 , wherein at least one of the tissue contacting surfaces includes a reflective element configured to reflect light passing through the tissue.

10. The end effector assembly according to claim 3 , wherein the 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 defined by at least one of the first jaw member or the second jaw member.
