Intended Use

The enSpire™ Discectomy System is intended for use in cutting, grinding and aspirating intervertebral disc material during discectorny procedures in the cervical, thoracic and lumbar spine.

Device Story

The enSpire™ Discectomy System is a single-use, battery-powered, handheld surgical device used by physicians in operating rooms or medical suites. It features a working shaft with a distal serrated cutting window and an internal auger mechanism. During operation, the motor-driven auger rotates against entrapped tissue and the fixed cutting window to cut and grind intervertebral disc material. The excised debris is then aspirated through the working shaft into an integrated collection chamber. The device is used percutaneously, endoscopically, or in open surgery, with visualization provided by direct view, fluoroscopy, or other imaging modalities. By enabling controlled tissue removal, the device assists in discectomy procedures, potentially benefiting patients by facilitating spinal decompression.

Clinical Evidence

Bench testing only. No clinical data provided. In-vitro studies evaluated cannula compatibility, switch durability, deployment/retraction, shaft length, device durability, travel limiter function, tensile strength, articulation, visualization, peak operating temperature, electromagnetic compatibility, electrical safety, packaging, shipping, sterility, shelf life, and biocompatibility (cytotoxicity, sensitization, irritation, systemic toxicity). Testing confirmed tissue volume/material removal without breach of annulus or endplates.

Technological Characteristics

Single-use, battery-powered (9V or 18V) mechanical discectomy device. Features a straight or articulating working shaft with a non-expandable serrated cutting window. Materials: Stainless steel. Sterilization: Gamma. Connectivity: None. Operates via mechanical auger rotation for tissue excision and aspiration. Complies with IEC 60601-1 for electrical safety.

Indications for Use

Indicated for patients undergoing discectomy procedures in the cervical, thoracic, and lumbar spine requiring cutting, grinding, and aspiration of intervertebral disc material.

Regulatory Classification

Identification

An arthroscope is an electrically powered endoscope intended to make visible the interior of a joint. The arthroscope and accessories also is intended to perform surgery within a joint.
