AI Technical Summary
Technical Problem
The existing bone drill handle cannot be judged quickly and accurately in the judgment of faults, which affects the efficiency of surgery.
Method used
A chuck module is designed, including a connecting sleeve, a chuck assembly and a connecting bearing. The chuck assembly is locked and cooperated with the plug end of the drill bit assembly through the locking force and friction force to synchronize the rotation of the chuck assembly, so as to determine the handle failure when the drilling end is not rotated.
Benefits of technology
It realizes the rapid and accurate judgment of whether the drilling handle has failed when the drilling end is not rotated, and improves the surgical efficiency.

Abstract
The utility model relates to a chuck module, a bone drilling handle and a bone drilling device. An inserting end is inserted into an inserting channel and is in locking fit with a chuck assembly; therefore, when the drilling end of the drill bit assembly is in a load state, the whole drill bit assembly can be driven to rotate by starting the handle body so as to drill bone tissues such as skull and the like. Moreover, the inserting end is inserted into the inserting channel and matched with the chuck assembly in a locking mode, even if the drilling end is in a no-load state due to the fact that the drilling end does not abut against an external object, the handle body is started and drives the inserting end to rotate, and meanwhile under the action of locking force and friction force, the drilling end is locked and matched with the chuck assembly. When the bone drilling handle breaks down, the inserting end synchronously drives the chuck assembly to rotate around the central axis of the inserting end relative to the connecting sleeve, namely, the drilling end does not rotate at the moment, whether the bone drilling handle breaks down or not can be rapidly and accurately judged by observing the rotation condition of the part, located outside the mounting cavity, of the chuck assembly, and the operation efficiency is guaranteed.
