Pulmonary Nodules Localization Solution

With the widespread adoption of low-dose CT, the detection rate of pulmonary nodules has increased significantly. However, some nodules are small in size, deeply located, or non-superficial in growth, making them difficult to visualize directly or locate by tactile palpation during thoracoscopic surgery.

Traditional intraoperative localization methods lack sufficient accuracy, often resulting in deviation of lesion targeting. This leads to unnecessarily extended resection margins and increased damage to healthy lung tissue.

Inaccurate nodule localization prolongs intraoperative exploration time and increases surgical difficulty. In severe cases, inability to precisely locate the lesion may necessitate conversion from VATS to open thoracotomy, significantly elevating surgical risk and trauma.

The Pulmonary Nodules Localization Needle is specifically designed for preoperative localization prior to VATS. Under CT guidance, it enables precise percutaneous puncture, providing a dedicated preoperative localization solution for difficult-to-locate lesions such as deep or small nodules, effectively addressing the challenge of intraoperative identification.

Featuring a four-prong anchoring hook structure made of nitinol memory alloy, the hooks remain retracted during puncture and automatically expand into shape upon proper positioning, securely anchoring in the lung tissue adjacent to the nodule for stable, migration-resistant fixation.

After puncture, the needle body is withdrawn, leaving a color-coded localization thread at the lesion site. The visible thread marker enables rapid, precise identification of the nodule location during surgery, eliminating blind exploration and effectively reducing operative time and resection of healthy lung tissue.

The product provides clear, reliable localization with high stability, significantly reducing the risk of conversion to open thoracotomy due to localization failure. It enhances the precision and safety of VATS pulmonary nodule procedures and is compatible with a wide range of thoracoscopic minimally invasive resection techniques.

This product is intended for CT-guided localization of pulmonary nodules in patients prior to thoracoscopic surgery.

Anchor Hook Design for Secure Fixation– Features a four-prong rounded barbed configuration for reliable tissue engagement, with blunt tips that effectively reduce the risk of bleeding.

Flexible Thread Localization for Low Migration Risk– The flexible thread effectively buffers traction forces, minimizing anchor migration and ensuring more stable positioning.

Visual Depth Indication for Intuitive Identification– Color-coded depth markings allow for easy identification of nodule depth, facilitating accurate intraoperative judgment.

This product enables precise deployment of the four-prong anchoring hook to the periphery of the pulmonary nodule under CT guidance, achieving a high localization success rate and providing reliable, clear intraoperative guidance. The blunt four-hook design delivers sufficient anchoring force while minimizing damage to lung tissue, resulting in a low incidence of postoperative complications.

The color-coded segmented localization thread allows for intuitive assessment of lesion depth and orientation during surgery, significantly reducing intraoperative endoscopic exploration time and improving procedural efficiency. The stable, durable anchoring effect provides a sufficiently long effective time window between localization and surgery, facilitating flexible scheduling for surgical teams and allowing both physicians and patients to plan procedures with greater ease.

Ultimately, with its stable and reliable intraoperative guidance, this product effectively resolves the clinical challenge of "cannot locate, cannot palpate" during VATS procedures, significantly reducing the risk of conversion to open thoracotomy due to localization failure, and ensuring the success rate and safety of minimally invasive surgery.
