The torque limiting screwdriver handle is designed to prevent over-tightening of locking screws in orthopedic implants. Once the pre-set torque limit (e.g., 1.5NM or 4.0NM) is reached, the mechanism slips or releases, ensuring the screw is securely tightened without damaging the bone, screw threads, or implant plate.
These handles are manufactured using high-grade medical stainless steel. This ensures excellent durability, corrosion resistance, and compatibility with standard clinical sterilization processes.
The AO type and Triangle type refer to the connection interface at the tip of the handle where the screwdriver shaft inserts. AO is a quick-coupling standard widely used in orthopedic instruments, while the Triangle type features a specific triangular drive configuration. Please choose the type that matches your existing screwdriver shafts.
Yes, being made of medical-grade stainless steel, these torque limiting handles are designed to withstand standard autoclave sterilization cycles and are fully reusable for surgical procedures.
The torque value should be chosen based on the specific orthopedic implant system and screw size you are using. Generally, smaller screws (such as 1.5mm or 2.0mm locking screws) require lower torque limits like 0.4NM or 0.8NM, while larger reconstruction screws may require 1.5NM or 4.0NM. Always refer to the implant manufacturer's technical specifications.
