Treatment of breast disease with vibrating device
View Patent ↗An elongate probe, with a suction channel extending longitudinally along the probe, is inserted into a patient so that a distal tip of the probe is in contact with a fibroid mass inside the patient. Thereafter the probe is ultrasonically vibrated so that the distal tip has an excursion amplitude or distance greater than 275 microns. During probe vibration, suction is applied to the channel at a vacuum level greater than 24″ Hg to thereby maintain the target tissue mass in engagement with the distal tip during the vibrating of the probe and enable ablation of at least a selectable portion of the target tissue mass.
1. A surgical method comprising:
providing an elongate probe and a suction channel extending longitudinally along said probe;
inserting a distal end portion of said probe into a breast of a patient so that a distal tip of said probe is in contact with a target fibroid tissue mass inside the patient's breast;
after contact of said distal tip with the target fibroid tissue mass inside the patient's breast, ultrasonically vibrating said probe so that said distal tip has an excursion amplitude or distance greater than 275 microns;
during the vibrating of said probe, applying suction to said channel at a vacuum level greater than 24″ Hg;
maintaining the target fibroid tissue mass in engagement with said distal tip during the vibrating'of said probe by virtue of the application of suction to said channel at a vacuum level greater than 24″ Hg; and
ultrasonically ablating at least a selectable portion of the target fibroid tissue mass in response to the vibrating of said probe.
2. The method defined in claim 1 , further comprising extracting a biopsy sample of said target fibroid tissue mass while said distal end portion of said probe is disposed in the patient's breast.
3. The method defined in claim 2 wherein the extracting of said biopsy sample includes:
inserting a biopsy cannula into said channel;
advancing said cannula through said channel;
inserting a distal end of said cannula into said target fibroid tissue mass inside the patient's breast;
subsequently withdrawing said cannula from said channel and from the patient; and
connecting a suction source to said probe.
4. The method defined in claim 2 wherein the extracting of said biopsy sample includes providing a biopsy trap in a suction line communicating with said channel, thereby trapping tissue during the ultrasonic vibrating of said probe tip.
5. The method defined in claim 1 , further comprising conducting electrical current to said distal tip and from said distal tip into tissues of the patient to effect a cauterization of bleeding blood vessels.
6. The method defined in claim 5 wherein the conducting of said electrical current is undertaken simultaneously with the vibrating of said probe.
7. The method defined in claim 1 , further comprising feeding an irrigation fluid to said probe tip to enhance cavitation forces, irrigate and cool the operative site and provide a carrier for ablated tissue.
8. The method defined in claim 7 wherein said irrigation fluid includes a dissolved additive taken from the group consisting of an anesthetic and an antibiotic.
9. The method defined in claim 1 , further comprising scanning the patient in a region about the target fibroid tissue mass and generating an image of the target fibroid tissue mass on a display, the inserting of said probe into the patient being done under visualization.
10. The method defined in claim 1 wherein said channel is formed as a bore passing longitudinally through said probe, the applying of suction to said channel including providing a suction source connected to said probe.
11. The method defined in claim 1 wherein said channel is formed by a sheath or cannula, the inserting of said distal end portion of said probe into the patient including deploying said probe so that it extends longitudinally through said channel.
