The present invention provides systems and methods for selectively applying electrical energy to a target location within a patient's body, particularly including tissue in the spine. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals in the presence of electrically conductive fluid or saline-rich tissue to contract collagen fibers within the tissue structures. In one aspect of the invention, a system and method is provided for contracting a portion of the nucleus pulposus of a vertebral disc by applying a high frequency voltage between an active electrode and a return electrode within the portion of the nucleus pulposus, where contraction of the portion of nucleus pulposus inhibits migration of the portion nucleus pulposus through the fissure.

Methods for treating an annulus fibrosis having a defect include inserting a flexible device into the defect. The flexible device is advanced distally beyond an outer layer of the annulus fibrosus. The flexible device is then expanded such that a width of the flexible device is larger than the defect, where the flexible device prevents escape of nucleus pulposus through the defect. The flexible device may have at least two appendages made from a shape-memory metal. Alternatively, the flexible device may have a U-shaped structure that includes a central portion and two legs. The flexible device may also be anchored to the annulus fibrosis and/or the vertebrae.

A method for performing a selective discectomy is disclosed whereby a path for insertion of a tissue removal device is created by inserting a cannula with a flexible distal end position into an intervertebral disc by entering the nucleus at a point contralateral or anterolateral to a herniation site or entering anterior or anterolateral relative to the herniation site. The path is followed by a cutting device with a cutting window and either or both of the cannula or cutting device may be positioned at a site of herniation using all of any of control wires, a set of styli, viewable markings on a component and/or visualization devices.

Methods and devices are described for occluding openings in an annulus fibrosis to prevent conditions such as disc herniation and recurrent disc herniation. An occluding device having an intradiscal component, an extradiscal component, and a barrier element disposed between the intradiscal and extradiscal components is provided. The intradiscal component has first and second arms having a collapsed state with a horizontal dimension less than the width of the opening and an expanded state having a horizontal dimension greater than the width of the opening. The barrier element and the intradiscal component in the collapsed state are inserted through the annulus fibrosis opening, the extradiscal component being positioned adjacent an outer surface of the annulus fibrosis. The intradiscal component assumes the expanded state in the intradiscal space, the first and second arms urging the barrier element against the inner wall of the annulus fibrosis adjacent the opening, thereby occluding the opening.

Systems and methods for treating disc herniation or degeneration, disc degeneration, and vertebral body fracture include surgical and endoscopic access and removal of disc tissue. The tissue removal devices that may be used include rotatable blade devices having flow control surfaces that may be inserted into a vertebral disc and rotated to pulverize the disc material and facilitate its removal.

The invention discloses a medicament for treating disc herniation which is prepared mainly from astragalus root, Ligusticum wallichii, corydalis tuber, safflower, root of red rooted saliva, spatholobus stem, wood louse, Chinese angelica root, prepared Sichuan aconite root, prepared wild aconite root, pubescent angelica root, notopterygium root, Loranthus mulberry mistletoe, pawpaw, ledebouriella root, cassia twig, large-leaf gentian root, tetrandra root, coralbean bark, dipsacus root, morinda root, achyranthes and cyathula root, wolferry fruit, earthworm, gastrodia tuber, oyster shell, root of herbaceous peony, oriental water plantain rhizome, kudzu vine root, poria cocos, poria cocos and licorice root by a predetermined weight proportions.

Methods and apparatus for treating disc herniation provide a conformable device which assumes a first shape associated with insertion and a second shape or expanded shape to occlude the defect which typically follows partial discectomy. The device may take different forms according to the invention, including patches size to cover the defect or plugs adapted to fill the defect. In a preferred embodiment, however, the device is a gel or other liquid or semi-liquid which solidifies to occlude the defect from within the body of the disc itself. In another preferred embodiment, a mesh screen is collapsed into an elongated form for the purposes of insertion, thereby minimizing the size of the requisite incision while avoiding delicate surrounding nerves. Such a configuration also permits the use of instrumentation to install the device, including, for example, a hollow tube or sheath adapted to hold the collapsed screen, and a push rod to expel the collapsed device out of the sheath for use in occluding the disc defect. A device according to the invention may further include one or more anchors to assist in permanently affixing the device with respect to the defect.

Surgical staples and annulus closure tools, used in methods of repairing torn body tissue, implementing inter-vertebral disk surgery, sealing an inter-vertebral disk incision, preventing or inhibiting disk herniation, and/or stimulating or facilitating healing of an inter-vertebral disk; have two, three or four legs attached by connecting members. The legs optionally have projections protruding therefrom to restrict motion of the staple relative to the body tissue, and said projections may be angled to restrict motion in any desired direction.

The invention relates to a spinal surgery minimally invasive surgery navigation system. The spinal surgery minimally invasive surgery navigation system comprises an imaging portion, a treatment portion, and a navigation portion, wherein an imaging portion scanner performs scaning and imaging around a treatment object; the treatment portion includes a mechanical arm, a connecting rod, a power supply unit, a clipper, a puncture channel into a lesion of a spinal column, and an ablation electrode needle. The puncture channel is a minimally invasive surgical working cannula having a diameter of about 2 mm. The system has the advantages of simple structure, low cost and easy operation, and the CT and MRI images are combined to integrally reconstruct the intervertebral disc tissues of the patient's bone structure, nerves, blood vessels and compression nerves as well as the ligament before the surgery, according to the position of protrusion of intervertebral disc and the nerve compression, areasonable surgical approach is designed before the surgery, and the intraoperative scanning bone image is registered, a robot arm is remotely controlled to accurate ablate the compression nerve tissue through real-time navigation, and the safety and stability are good. The system avoids damage to normal tissues caused by doctor fatigue during surgery and effectively reduces the damage of radiation to patients and doctors.

The present invention relates to a probe and a device for detecting abnormality of an intervertebral disc. More particularly, the present invention relates to a probe and a device for detecting abnormality of an intervertebral disc that gives vibration stimulation to the inner part of the intervertebral disc and obtains an ultrasonic image in order to sense the abnormality of the intervertebral disc causing discogenic pains and inspects whether the intervertebral disc is abnormal by measuring impedance in the intervertebral disc.

The present invention provides a probe for detecting abnormality of an intervertebral disc including: a shaft connector; a vibration generator connected to the shaft connector; and an inspector connected to the vibration generator, wherein the vibration generator vibrates the inspector by using a piezoelectric element and a device for detecting abnormality of an intervertebral disc.
