Definitions
- the invention relates to a device for limiting a torque to be transmitted, according to the preamble of patent claim 1.
- bone screws are often self-drilling and self-tapping and are screwed into the bone with a drill or similar device.
- the maximum torque, which is effective on the bone screw and thus on the threaded connection between bone screw and bone, should be limited to a certain value.
- a device for limiting the maximum torque that can be applied to a screw during a surgical procedure is known from US 6,132,435 YOUNG.
- This known device comprises a driving shaft, which contains a disc-shaped segment with arranged on a concentric circle to the axis of rotation bores for receiving balls, an abortive shaft segment which includes a likewise disc-shaped segment with complementary to the bores, dome-shaped recesses, and a housing wherein the driving shaft and the driven shaft segment are supported.
- the balls are pressed by means of springs in the recesses in the disc-shaped segment of the abortive shaft segment, wherein the spring force is adjustable by loosening or tightening a threaded connection between the disc-shaped segment on the driving shaft and the housing.
- a disadvantage of this known device is that the same maximum torque is transmitted in both directions. This is unfavorable in the surgical technique, when the bone screw is slightly ingrown during explantation and thereby the release torque is increased.
- the invention aims to remedy this situation.
- the invention has for its object to provide a device which allows the transmission of a once set maximum torque only in a desired direction of rotation, while in the other direction of rotation, for example, for loosening bone screws, the transmittable torques may be larger or smaller.
- the device according to the invention essentially comprises two transmission parts arranged coaxially with respect to a longitudinal axis and a likewise coaxially arranged housing for supporting the transmission parts, wherein at least one of the transmission parts is rotatably mounted about the longitudinal axis in the housing. Furthermore, elastic means are inserted in the housing. Also in the housing clamping means are arranged, by means of which the elastic means can be prestressed to a desired biasing force.
- the transmission parts are provided with complementary teeth which can be brought into engagement with one another and which can be pressed against each other by the elastic means and the maximum transmissible torque can be limited by the biasing force of the elastic means.
- the housing may be formed as a handle, so that the transmission parts can be integrated directly into the handle.
- the flank angle of the teeth on the teeth are preferably unequal in size, so that the asymmetric configuration of the teeth allows a torque transmission whose maximum transmittable torque is not equal in both directions of rotation.
- the passive during the torque transmission in the desired direction of rotation tooth flanks of the two teeth close with the perpendicular to the longitudinal axis diameters of the transmission parts an angle ß, which is between 45 ° and 90 °.
- tooth flanks of the two teeth close with the standing perpendicular to the longitudinal axis
- the transmission parts an angle ⁇ , which may be between 1 ° and 45 °.
- the tooth flanks be designed such that the angle ⁇ A on the outer diameter of the teeth and the angle ⁇ on the inner diameter of the teeth are designed unequal size. This results in a line contact on the entire tooth width and no punctiform load, which has a negative effect in particular on the wear properties.
- the teeth of the two teeth open rounded in the respective end face.
- the radii of these roundings amount to between 0.1 mm and 1, 0 mm. By choosing this radius, the wear behavior can be optimized.
