Abstract

An ultrasonic surgical device (10) for the coagulation of animal tissue havi ng an ultrasonic applicator (13) and a movable jaw (15) with a jaw surface (16) adjacent the distal portion of the ultrasonic applicator (13) for movement toward the applicator (13) to a closed position at a predefined clearance (2 2) of between about 0.075 to about 1.9 millimeters from the applicator (13). Th e device (10) may also include a mechanical cutting element (20) that can be extended into the clearance to cut the tissue and means to vary the predefin ed clearance (22) without removing the applicator (13) from the patient. Tissue coagulating and cutting can be maximized and performed separately and can be easily monitored by the surgeon.

Claims (26)

1. An ultrasonic surgical apparatus for the coagulation of animal tissue having a handle for manipulation by a surgeon, an ultrasonic transducer for generating ultrasonic vibration, and an ultrasonic applicator attached to the ultrasonic transducer and extending from the handle for delivery of ultrasonic vibrations to the tissues of the animal, wherein said apparatus further comprises:
a distal portion on the ultrasonic applicator having a generally round cross-section with a diameter between approximately 2 and 6 millimeters to provide a broad surface for coagulation and to avoid cutting of the animal tissue;
an elongated support member releasably attached to the surgical handle and extending to the distal portion of the ultrasonic applicator; and a movable jaw with a jaw surface attached to the elongated support member adjacent the distal portion of the ultrasonic applicator for movement toward said distal portion to a closed position at a predefined clearance of between about 0.075 to about 1.9 millimeters, from said distal portion of the ultrasonic applicator.
2. The ultrasonic surgical apparatus of Claim 1 wherein the predefined clearance is between about 0.075 and about 0.75 millimeters.
3. The ultrasonic surgical apparatus of Claim 2 wherein the jaw surface in the closed position is generally parallel with the surface of the elongated support member.
4. The ultrasonic surgical device of Claim 2 wherein the jaw surface is concave.
5. The ultrasonic surgical device of Claim 2 wherein the jaw surface is convex.
6. The ultrasonic surgical device of Claim 2 wherein the jaw surface is flat.
7. The ultrasonic surgical device of Claim 2 wherein the predetermined clearance is determined by a stop located on the elongated support member.
8. The ultrasonic surgical device of Claim 2 wherein the predetermined clearance is determined by a stop located on the handle of the ultrasonic surgical device.
9. The ultrasonic surgical device of Claim 2 wherein the predetermined clearance may be varied without requiring removal of the ultrasonic surgical device from the patient during a medical procedure.
10. An ultrasonic surgical apparatus for the treating of animal tissue having a handle for manipulation by a surgeon, an ultrasonic transducer for generating ultrasonic vibration, and an ultrasonic applicator attached to the ultrasonic transducer and extending from the handle for delivery of ultrasonic vibrations to the tissues of the animal, wherein said apparatus further comprises:
a distal portion on the ultrasonic applicator having a generally round cross-section with a diameter between approximately 2 and 6 millimeters to provide a broad surface for coagulation and to avoid cutting of the animal tissue;
an elongated support member releasably attached to the surgical handle and extending to the distal portion of the ultrasonic applicator;
a movable jaw with a jaw surface attached to the elongated support member adjacent the distal portion of the ultrasonic applicator for movement toward said distal portion to a closed position at a predefined clearance of between about 0.075 to about 1.9 millimeters from said distal portion of the ultrasonic applicator to provide a zone for tissue flow and coagulation as the tissue is heated by vibration of the ultrasonic applicator; and a mechanical cutting device for movement parallel to the ultrasonic applicator to cut the tissue located between the ultrasonic applicator and the clamp.
11. The ultrasonic surgical apparatus of Claim 10 wherein the predefined clearance is between about 0.075 and about 0.75 millimeters.
12. The ultrasonic surgical apparatus of Claim 11 wherein the jaw surface in the closed position is generally parallel with the surface of the elongated support member.
13. The ultrasonic surgical device of Claim 11 wherein the jaw surface is concave.
14. The ultrasonic surgical device of Claim 11 wherein the jaw surface is convex.
15. The ultrasonic surgical device of Claim 11 wherein the jaw surface is flat.
16. The ultrasonic surgical device of Claim 11 wherein the predetermined clearance is determined by a stop located on the elongated support member.
17. The ultrasonic surgical device of Claim 11 wherein the predetermined clearance is determined by a stop located on the handle of the ultrasonic surgical device.
18. The ultrasonic surgical device of Claim 11 wherein the predetermined clearance may be varied without requiring removal of the ultrasonic surgical device from the patient during a medical procedure.
19. The ultrasonic surgical device of Claim 11 wherein the mechanical cutting device is a blade.
20. A method for the surgical coagulation of animal tissue comprising:
locating a portion of the animal tissue between an ultrasonic applicator having a generally round cross-section with a diameter between approximately 2 and 6 millimeters to provide a broad surface for coagulation and to avoid cutting of the animal tissue and a clamp located adjacent the ultrasonic tissue;
moving the clamp toward the ultrasonic applicator to a predefined clearance of between about 0.075 to about 1.9 millimeters from the ultrasonic applicator to provide a zone for tissue flow and coagulation; and applying ultrasonic vibrations to the portion of the tissue via the ultrasonic applicator sufficient to cause coagulation of the tissue.
21. The method of Claim 20 wherein the predefined clearance is between about 0.075 and about 0.75 millimeters.
22. The method of Claim 21 wherein the predetermined clearance may be varied without requiring removal of the ultrasonic surgical device from the patient during a medical procedure.
23. A method for the surgically animal tissue with minimal bleeding comprising:
locating the animal tissue between an ultrasonic applicator having a generally round cross-section with a diameter between approximately 2 and 6 millimeters to provide a broad surface for coagulation and to avoid cutting of the animal tissue and a clamp located adjacent the ultrasonic tissue;
moving the clamp toward the ultrasonic applicator to a predefined clearance of between about 0.075 to about 1.9 millimeters from the ultrasonic applicator to provide a zone for tissue flow and coagulation as the tissue is heated by vibration of the ultrasonic applicator;
applying ultrasonic vibrations to the portion of the tissue via the ultrasonic applicator sufficient to cause coagulation of the tissue, and cutting said tissue after it has been coagulated using a mechanical cutting device.
24. The method of Claim 23 wherein the predefined clearance is between about 0.075 and about 0.75 millimeters.
25. The method of Claim 24 wherein the predetermined clearance may be varied without requiring removal of the ultrasonic surgical device from the patient during a medical procedure.
26. The method of Claim 24 wherein the mechanical cutting device is a blade.
