In modern thyroid surgery, quality is measured not only by complete resection but also by in-situ parathyroid preservation—a key benchmark of surgical precision.
Parathyroid glands are pea-sized and extremely heat-sensitive, with delicate blood supply. Thermal injury or vascular damage can cause hypocalcemia and, in severe cases, permanent hypoparathyroidism requiring lifelong calcium supplementation.
During central compartment dissection and posterior capsular anatomy, conventional electrosurgery and ultrasonic devices each have limitations: electrosurgery spreads heat widely; ultrasonic devices have bulkier jaws and lateral thermal spread, often requiring wet gauze isolation and increasing preservation difficulty.
BBT Medical’s Twocan dual-energy scissors use proprietary low-temperature RF coagulation-cutting technology to address these gaps and support refined parathyroid-preserving thyroid procedures.
Low, controlled temperature protects parathyroid perfusion
Conventional ultrasonic devices rely on frictional heat that can spasm fine vessels—a major contributor to postoperative hypocalcemia. Twocan scissors operate at 40–70°C with lateral thermal spread ≤1 mm, allowing vessel handling near the thyroid capsule without saline isolation while protecting parathyroid perfusion.
Slim tips enable thin-layer capsular dissection
In-situ preservation depends on meticulous separation between true and false capsules. Conventional ultrasonic scissors are wide and awkward in tight posterior spaces. Twocan scissors use micro-refined tips for flexible opening and closing, enabling dissection, hemostasis, and transection with one instrument.
Simultaneous coagulation and cutting reduce cumulative thermal injury
Traditional workflows often coagulate then cut with separate tools, stacking energy in the same zone. Twocan completes grasping, coagulation, and cutting in one step with a single energy application.
No vibrating structure eliminates blade fracture risk
Ultrasonic devices can rarely fracture in dense tissue, creating retained metal fragment risk. Twocan has no vibrating components, uses an integrated alloy jaw, produces minimal char and smoke, and keeps the field clear for parathyroid identification.
Cost efficiency aligned with DRG payment reform
One Twocan scissors can replace bipolar forceps plus tissue scissors, reducing table setup, instrument changes, and operative time while improving parathyroid protection and shortening calcium supplementation—supporting better DRG margins.
For breast and thyroid surgery, Twocan combines ultrasonic-like cutting with fine bipolar coagulation: slimmer and more agile than ultrasonic devices, with less thermal spread than electrosurgery—limiting energy to target tissue while preserving parathyroid blood supply.
As BBT Medical’s new domestic solution for refined parathyroid-preserving surgery, Twocan helps hospitals balance clinical safety and operational efficiency under DRG reform.
