Adjustable-length surgical access devices are disclosed herein, which can advantageously allow an overall length of the access device to be quickly and easily changed by the user. The access devices herein can reduce or eliminate the need to maintain an inventory of many different length access devices. In some embodiments, the length of the access device can be adjusted while the access device is inserted into the patient. This can reduce or eliminate the need to swap in and out several different access devices before arriving at an optimal length access device. This can also reduce or eliminate the need to change the access device that is inserted into a patient as the depth at which a surgical step is performed changes over the course of a procedure. Rather, the length of the access device can be adjusted in situ and on-the-fly as needed or desired to accommodate different surgical depths.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

A method for treating spinal nerve compression includes sequential dilation to position an instrument cannula along a patient's spine. Instruments can be delivered through the instrument cannula to remove targeted tissue for a decompression procedure. One of the instruments can be a reamer instrument configured to abrade, cut, or otherwise affect tissue along the patient's spine.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, ultra-MIS techniques.

The present disclosure relates to an openable/closable vertebral endoscopic device. The openable/closable vertebral endoscopic device includes an endoscope body including a working channel for providing an access route of a surgical instrument to a diseased area of a human body, the working channel having an open channel formed by opening a portion of the working channel such that a portion of the surgical instrument inserted into the working channel is exposed to the outside; and a cover member provided on the endoscope body to selectively open or close the open channel of the endoscope body.

The present disclosure includes devices and methods of treating a herniated disc comprising treating an opening in a vertebral disc by applying plasma to the vertebral disc, wherein the vertebral disc comprises a nucleus portion and an outer annulus fibrosus portion, and wherein the plasma seals the opening in the vertebral disc. The devices and method comprises a plasma delivery device configured to be handheld and used percutaneously or in minimally invasive surgery. The vertebral disc, which comprises a nucleus pulposus and an outer annulus fibrosus, can be herniated with a rupture caused by a tear or opening in the annulus fibrosus, that can be repaired when the annulus fibrosus is sealed by the use of the plasma.

An endoscopic pedicle probe for use during spinal surgery to form a hole in a pedicle for reception of a pedicle screw has an enlarged proximal end for cooperation with the hand of the surgeon and an elongate shaft terminating in a distal tip that may be pushed through the pedicle to form the hole. The tip may be detachable for replacement. An endoscope extends through the shaft and is connected with a monitor to enable the surgeon to visually observe the area being treated. In a preferred form a light means extends through the shaft to illuminate the area being treated, and in a further preferred form a conduit extends through the shaft to convey a fluid to flush the area being treated. In a further embodiment, two endoscopes are associated with the probe.

A method for treating or repairing a damaged spinal disc of a patient may include inserting, using medical imaging, a shaft with a lumen extending from an exterior of a patient to the damaged spinal disc, dispensing copper particles, using the lumen, to the damaged spinal disc, and removing the hollow shaft from the patient. A system may include a syringe and copper particles in the syringe. A kit may include copper particles, and at least one of a guidewire, one or more dilators, a tubular retractor, a disposable endoscope, a disposable laser fiber; an endoscopic ronjeurs, indigo carmine dye, or a fluid adaptor.

The present invention relates to a flexible surgical system for endoscopic spinal decompression and methods thereof. Various methods of accessing the epidural space with this instrument are described. The system design enables placement of the device through several approaches. It is then advanced under direct visualization or fluoroscopic (X-Ray), for example, into areas of the spine including lumbar (low back), thoracic (mid and upper back) and cervical (neck). The pathologies encroaching upon the spinal space can then be visualized wherein the epidural membrane can optionally be displaced to further aid in visualization. The membrane can be used to protect regions of tissue adjacent the site to tissue removal.
