  • Torque limiting dental tool holder
    Patent number: 10463449
    Abstract: A torque limiting device for use with a dental drive tool including a housing defining a rotation axis and having a bore concentric with the rotation axis and a torque limiting insert. The housing has a recess for housing at least part of the torque limiting insert. The torque limiting insert includes a fixing region held within the housing and a spring region extending from the fixing region and including a locking catch protruding into the bore. The locking catch is aligned with the recess so it can be moved radially outwards into the recess in to a disengaged position. The locking catch is arranged to engage with the dental drive tool when the tool is introduced in the bore to transmit a torque applied to the housing and to deflect into the disengaged position against the force of the spring region when a predefined torque limit is reached.
