Electronic Dental Torque Wrench With Sensor-Based Torque Control

The patent replaces mechanical torque indication systems with electronic force sensors (strain gauges) that convert mechanical force into electrical signals. This substitution enables precise torque measurement through electronic means while maintaining a relatively compact device structure, directly resolving the contradiction between measurement precision and device complexity.

The torque wrench is divided into distinct modular segments: a sterilizable mechanical body and a separate electronic monitoring module. The force sensors and evaluation unit can be integrated into a removable head portion that can be sterilized independently, while the electronic processing occurs in a separate compartment. This segmentation allows high-reliability electronic monitoring without compromising sterilization capabilities.

The electronic components including force sensors are extracted from the main shaft body and integrated into a separate head module. This extraction allows the shaft to remain as a simple, sterilizable mechanical component while the head contains all electronic sensing and processing elements. The modular design enables the shaft to be easily sterilized without electronic components interfering with the process.

An intermediary evaluation unit serves as a bridge between the force sensors and external data management systems. This intermediary processes torque data locally, stores it temporarily, and interfaces with external devices (computers, cloud systems) for comprehensive data management. This approach enables complete digital documentation without requiring complex integrated storage and processing systems within the torque wrench itself.
