Abstract

A tissue clip for use in electrosurgical procedures 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 method of sealing tissue, comprising:

grasping and positioning a first tissue clip within a body of a patient using a surgical instrument or a hand;

grasping a first portion of tissue of the patient between an arm and a body of the first tissue clip;

releasing the first tissue clip from the surgical instrument or the hand; and

energizing an electrode of at least one of the arm or the body of the first tissue clip by a power source disposed within the body of the first tissue clip, thereby sealing the grasped first portion of the tissue, wherein the electrode is energized after the tissue clip is released.

2. The method according to claim 1, wherein the first tissue clip is grasped and positioned within the body of the patient using the surgical instrument.

3. The method according to claim 2, wherein releasing the first tissue clip includes ungrasping the first tissue clip with the surgical instrument.

4. The method according to claim 1, further comprising:

moving the arm away from the body to ungrasp the sealed first portion of the tissue; and

removing the tissue clip from the body of the patient.

5. The method according to claim 1, further comprising:

grasping and positioning a second tissue clip within the body of the patient with the surgical instrument or the hand;

grasping a second portion of the tissue of the patient between an arm and a body of the second tissue clip;

releasing the second tissue clip from the surgical instrument or the hand; and

energizing an electrode of at least one of the arm or the body of the second tissue clip from a power source disposed within the body of the second tissue clip, thereby sealing the grasped second portion of the tissue, wherein the electrode is energized after the second tissue clip is released.

6. The method according to claim 5, wherein the second tissue clip is grasped and positioned within the body of the patient using the surgical instrument.

7. The method according to claim 6, wherein releasing the second tissue clip includes ungrasping the second tissue clip with the surgical instrument.

8. The method according to claim 5, further comprising removing the first and second tissue clips from the body of the patient using the surgical instrument or the hand after the first and second portions of the tissue are sealed.

9. The method according to claim 1, wherein the arm has a proximal end portion movably coupled to a proximal end portion of the body, the method further comprising moving the arm relative to the body to grasp the first portion of the tissue.

10. The method according to claim 1, further comprising applying a sealing pressure on the first portion of the tissue via a biasing member that biases the arm relative to the body.

11. The method according to claim 1, further comprising transmitting instructions to the first tissue clip from an external control unit.

12. The method according to claim 1, wherein grasping the first portion of the tissue stops blood flow through the first portion of the tissue.

13. The method according to claim 1, further comprising transferring electrosurgical energy from the power source to the electrode to energize the electrode using a control unit disposed within the first tissue clip.

14. The method according to claim 1, further comprising determining parameters of the first portion of the tissue using a sensor of the first tissue clip.

15. The method according to claim 1, further comprising:

sensing that the first portion of the tissue is sealed using a sensor of the first tissue clip; and

automatically activating a cutting element of the first tissue clip after the sensor senses that the first portion of the tissue is sealed.

16. The method according to claim 1, further comprising applying a closure pressure between 3 kg/cm² to 16 kg/cm² on the first portion of the tissue by the arm and the body prior to energizing the electrode.

17. The method according to claim 1, further comprising setting a gap in the range of 0.001 inches to 0.006 inches between the arm and the body with a stop member disposed between the arm and the body.

18. A method of sealing tissue, comprising:

positioning a first tissue clip within a body of a patient using a surgical instrument having the first tissue clip coupled thereto;

grasping a first portion of tissue of the patient between an arm and a body of the first tissue clip;

releasing the first tissue clip from the surgical instrument; and

energizing an electrode of at least one of the arm or the body of the first tissue clip by a power source disposed within the body of the first tissue clip, thereby sealing the grasped first portion of the tissue, wherein the electrode is energized after the tissue clip is released.

19. A method of sealing tissue, comprising:

positioning a surgical instrument having a tissue clip coupled thereto within a body of a patient;

grasping a portion of tissue of the patient between an arm and a body of the tissue clip;

uncoupling the tissue clip from the surgical instrument thereby energizing an electrode of at least one of the arm or the body of the tissue clip by a power source disposed within the body of the tissue clip thereby sealing the grasped portion of the tissue.
