Abstract

The present disclosure is directed to a tissue clip for use in electrosurgical procedures. The tissue clip includes an arm having a first electrode formed thereon. The tissue clip also includes a body pivotally coupled to the arm. The body includes a power source and a second electrode. The arm is moveable from a first position relative to the body for approximating tissue and a second position closer to the body for grasping tissue therebetween.

Claims

1. A tissue clip, comprising:

an arm having a first electrode and a proximal end portion;

a body having a proximal end portion pivotally coupled at the proximal end portion of the arm such that the arm is moveable from a first position relative to the body for approximating tissue and a second position closer to the body for grasping tissue therebetween, the body including;

a housing;

a power source disposed within the housing of the body; and

a second electrode coupled to the power source; and

a biasing member configured to generate an appropriate sealing pressure to tissue grasped between the arm and the body by biasing the arm relative to the body.

2. The tissue clip according to claim 1, further comprising a control unit configured to transfer energy from the power source to the first and/or second electrode.

3. The tissue clip according to claim 1, wherein the body includes an antenna configured to communicate with an external control unit.

4. The tissue clip according to claim 1, further comprising a sensor array configured to determine parameters of tissue between the arm and the body.

5. The tissue clip according to claim 1, wherein the first electrode and/or second electrode includes:

a stainless steel layer; and

a copper layer.

6. The tissue clip according to claim 1, wherein the first electrode and/or second electrode includes piezo electric sensors.

7. The tissue clip according to claim 1, wherein the first electrode includes:

an outer layer composed of a non-stick material; and

a flex circuit having a coil formed thereon.

8. The tissue clip according to claim 2, wherein the first electrode and second electrode cooperate with the control unit and the power source to seal tissue.

9. The tissue clip according to claim 8 further comprising a cutting element having an electrode configured to electrically cut tissue.

10. The tissue clip according to claim 9, wherein the cutting element cooperates with the control unit to cut tissue after the seal is completed.

11. The tissue clip according to claim 10, further comprising at least one sensor configured to sense the completed seal.

12. The tissue clip according to claim 11, wherein the control unit automatically activates the cutting element when the at least one sensor senses the completed seal.

13. The tissue clip according to claim 8, wherein the first electrode includes a first pair of tissue contacting surfaces and an insulator disposed therebetween and the second electrode includes:

a second pair of tissue contacting surfaces;

a pair of insulators disposed between the second pair of tissue contacting surfaces; and

a cutting element disposed between the pair of insulators.

14. The tissue clip according to claim 13, wherein the cutting element includes an electrode that is configured to electrically cut tissue.

15. The tissue clip according to claim 9, wherein the cutting element is moveable to cut tissue after the formation of the tissue seal.

16. The tissue clip according to claim 1, wherein the first electrode of the arm is disposed distally of the proximal end portion of the arm.

17. The tissue clip according to claim 1, wherein the second electrode of the body is disposed distally of the proximal end portion of the body.

18. The tissue clip according to claim 2, wherein the control unit is disposed within the housing of the body.

19. The tissue clip according to claim 1, wherein the proximal end portion of the arm is connected to the proximal end portion of the body via a flexible joint.
