Spine Cannulated Pedicle Screw Instrument Set

The Spine Cannulated Pedicle Screw Instrument Set is designed for orthopedic and spinal procedures requiring controlled preparation and placement of cannulated pedicle screws. Cannulated instrumentation allows selected tools to work over a guidewire or guide pin, helping the surgeon maintain a defined trajectory during pedicle access and implant placement.

Pedicle screw fixation is commonly used as part of posterior spinal stabilization and fusion procedures. Depending on the surgical technique and implant system, pedicle screws may be used to provide segmental fixation and support spinal constructs involving rods or other compatible components. The exact indications, vertebral levels, and fixation strategy are determined by the surgeon based on patient anatomy, pathology, and the selected implant system.

A dedicated cannulated pedicle screw instrument set can support several stages of the procedure. Depending on the configuration, instruments may assist with pedicle localization, access preparation, tapping, trajectory control, screw insertion, and final positioning. Cannulated drivers and related instruments are designed to work with compatible guidewires or guide pins where applicable.

The cannulated design is particularly useful when a guidewire-based technique is selected. The guidewire can help establish and maintain the intended trajectory while compatible instruments are advanced over it. Proper control of the guidewire and continuous assessment of its position are essential during the procedure to reduce the risk of unintended advancement or displacement.

The instruments are designed for controlled handling in the demanding environment of spinal surgery. Ergonomic handles and appropriately designed working ends can help provide tactile control during pedicle preparation and implant insertion. Exact instrument geometry, shaft length, coupling style, and working-end dimensions vary between systems, so compatibility with the intended pedicle screw system should always be verified before clinical use.

The set may be suitable for procedures involving different spinal regions depending on its configuration and the surgeon’s technique. Common applications of pedicle screw instrumentation include selected thoracic, lumbar, and lumbosacral fixation procedures. However, not every instrument or screw size is appropriate for every vertebral level or patient anatomy.

For reusable instruments, proper reprocessing is essential. Instruments should be cleaned promptly after use, thoroughly rinsed and dried, inspected for damage or wear, and sterilized using validated procedures specified by the manufacturer and healthcare facility. Cannulated shafts and internal passages require particular attention because retained biological material can compromise effective cleaning.

This Spine Cannulated Pedicle Screw Instrument Set provides organized instrumentation for surgeons performing spinal fixation procedures involving compatible cannulated pedicle screw systems. Before use, the complete instrument configuration, dimensions, connection mechanism, and implant compatibility should be verified against the applicable surgical system and manufacturer’s instructions.

Product Specifications

FAQs

1. What is a cannulated pedicle screw instrument set?

A cannulated pedicle screw instrument set contains specialized spine surgery instruments designed to support preparation and placement of compatible cannulated pedicle screws, including procedures using guidewires or guide pins.

2. What are cannulated pedicle screws used for?

Cannulated pedicle screws are used in selected spinal fixation and stabilization procedures. They may form part of a construct used for spinal fusion or other stabilization techniques, depending on the patient’s condition and surgical plan.

3. What is the purpose of cannulation in pedicle screw instruments?

Cannulation allows compatible instruments to pass over a guidewire or guide pin. This can help maintain a planned trajectory during selected stages of pedicle preparation and screw insertion.

4. Can this set be used with any pedicle screw system?

Not necessarily. Pedicle screw instruments can differ in dimensions, driver interfaces, threading, coupling mechanisms, and other design characteristics. Compatibility should be confirmed with the specific implant system before use.

5. Which spinal levels can use pedicle screw instrumentation?

Pedicle screw fixation may be used at selected thoracic, lumbar, and lumbosacral levels. The appropriate screw and instrument dimensions depend on vertebral anatomy, patient factors, surgical technique, and the selected fixation system.

6. What instruments may be included in a cannulated pedicle screw set?

Depending on the configuration, the set may include instruments for pedicle access, probing, tapping, guidewire handling, screw insertion, and related preparation steps. Exact contents should be confirmed from the supplied instrument list.

7. Are these spine instruments reusable?

Instruments designed as reusable surgical devices can be reprocessed according to validated manufacturer instructions and facility protocols. Cannulated instruments require thorough cleaning of their internal passages.

8. How should cannulated spine instruments be sterilized?

Reusable instruments should be cleaned, rinsed, dried, inspected, and sterilized using validated procedures appropriate to the specific instruments. The manufacturer’s reprocessing instructions should always be followed.
