Torque wrench with freewheeling mechanism for medical technology
The patent US12070372B2 describes a specialized torque wrench designed for medical technology, particularly in the field of dentistry. The wrench features a head region with a receptacle opening, a neck region, and a bar-shaped activation lever that applies torque. The design includes a bezel that defines a rotation axis and is configured to receive a driver instrument. A notable aspect of the wrench is its latching cam, which interacts with the driver instrument to transmit torque through an entrainment mechanism. This cam can move to a releasing position, allowing for a freewheeling mechanism when the activation lever is rotated counter to the tightening direction. The spring bracket, integral to the design, plays a crucial role in this mechanism and is shaped to facilitate the interaction with the driver instrument.
Additional claims detail various features of the torque wrench, including the configuration of the latching cam, the design of the spring bracket, and the structure of the bezel. The activation lever is described as flexural, allowing for torque measurement based on its deflection when force is applied. The indicator region of the wrench includes measurement marks for reading the generated torque. The design emphasizes a compact and efficient mechanism suitable for medical applications, ensuring precise torque application in dental procedures. Overall, the patent outlines a comprehensive and innovative tool that enhances the functionality of torque wrenches in medical settings.
