Product Description
The distractor features a finely calibrated gear mechanism that provides smooth, incremental distraction, allowing the surgeon to feel the tension of the soft tissues and avoid over-distraction.
The set includes a specialized twist drill with an integrated shoulder stop, ensuring that distraction pins are placed at a consistent, safe depth within the vertebral body every time.
Our pins are manufactured from hardened stainless steel with optimized thread profiles, providing superior grip in both osteoporotic and dense cortical bone to prevent pin "pull-out" under tension.
The distractor body is engineered with a slim profile to minimize interference with the surgical microscope and other instruments, maintaining a clear line of sight to the disc space.
Indicated for the distraction of the upper cervical spine where anatomical space is limited. The set’s precision allows for the safe opening of the disc space near the skull base.
The primary indication for standard ACDF procedures. The distractor provides the necessary force to overcome the tension of the longus colli muscles and anterior longitudinal ligament.
Applied in the treatment of traumatic cervical fractures or dislocations where significant distraction is required to reduce the deformity and realign the vertebral column.
Specifically indicated for multi-level cases where the distractor can be moved sequentially from one level to the next, maintaining consistent tension across the entire surgical construct.

The Cervical Distractor Instrument Set is a specialized orthopedic system used primarily in anterior cervical spine surgery. It consists of a rack-and-pinion distractor (often referred to as a Caspar distractor), distraction pins, and the drill/drivers required for pin placement. The system works by anchoring two pins into adjacent vertebral bodies; the distractor is then attached to these pins. By turning the adjustment knob, the surgeon can mechanically increase the distance between the pins, effectively opening the disc space. This is a critical step in ACDF, as it provides the access needed to remove disc material and restore height with a cage or bone graft.
This set is applied in Anterior Cervical Discectomy and Fusion (ACDF) and cervical corpectomy procedures. Its primary application is to create a stable, distended surgical corridor. Without this mechanical distraction, the disc space remains collapsed, making it difficult to fully decompress the nerve roots or insert a large enough interbody spacer. The set is used for treating cervical herniated discs, spondylotic myelopathy, and trauma-induced instability. It is an essential tool for any surgeon performing reconstructive surgery of the cervical anterior column.
The primary advantage of the TOOLMED set is its mechanical reliability and smooth operation. Many distractors suffer from "ratcheting" that can be jerky; our rack-and-pinion design ensures a fluid, continuous motion. Furthermore, the use of 17-4PH stainless steel ensures that the distractor body does not flex under the significant tension of the cervical ligaments. The set's inclusion of a dedicated drill guide and depth-stop drill ensures that pins are placed perfectly parallel and at a safe depth, reducing the risk of vertebral fracture or penetration into the spinal canal.
Biomechanically, the set is designed to work in harmony with the ligamentotaxis of the cervical spine. By providing parallel distraction, the instruments ensure that the force is evenly distributed across the vertebral endplates. This avoids the "wedging" effect that can occur with manual distraction. The pins are engineered to have a specific thread pitch that maximizes the "bone-to-metal" interface, ensuring that the distraction force is transmitted to the vertebral body without causing micro-fractures in the bone around the pin site.
The surgical technique begins with the exposure of the anterior cervical spine. The surgeon uses the drill guide and depth-stop drill to create two pilot holes in the midline of the vertebral bodies above and below the target disc. The distraction pins are then screwed into these holes. The distractor body is slid over the pins and secured. The surgeon turns the knob to open the disc space to the desired height, confirmed by fluoroscopy. After the disc is removed and the cage is placed, the distractor is closed, the pins are removed, and the small holes are filled with bone wax.
Postoperative care for the set involves a strict cleaning and inspection protocol. Because the distractor body contains a geared rack and multiple sliding surfaces, it must be thoroughly cleaned using enzymatic solutions to remove all biological debris. Ultrasonic cleaning is essential for the rack teeth. Following cleaning, the gears must be lubricated with medical-grade surgical lubricant to ensure continued smooth motion. The set is then steam-sterilized at 134°C. The distraction pins are typically single-use items to ensure maximum sharpness and structural integrity, but the main distractor is designed for long-term reusable service.
The TOOLMED Cervical Distractor Instrument Set is a cornerstone of anterior cervical surgery. By providing a stable, precise, and controlled method for vertebral distraction, it allows surgeons to perform complex decompressions and reconstructions with enhanced safety and predictable clinical outcomes.
Yes, the set can be configured with both orientations to accommodate the surgeon's preference or the side of the surgical approach (left vs. right-sided incision).
The pins are made from high-strength 17-4PH stainless steel, providing the necessary stiffness to avoid bending under the high loads of cervical distraction.
The set includes a drill guide that ensures the pins are inserted perfectly parallel. If pins are angled, the distraction force can cause them to toggle and loosen in the bone.
The distractor is designed for single-level distraction. For multi-level fusions, it is moved from level to level, or multiple distractors can be used if simultaneous distraction is required.
The standard rack allows for up to 40mm of distraction, which is more than sufficient for any standard cervical disc space or corpectomy gap.
