The invention discloses a medical torque screwdriver. The medical torque screwdriver comprises a screwdriver rod, a screwdriver handle, a compression spring, an intra-handle movable piece, a first tooth-shaped part, a second tooth-shaped part and a nut. A screwdriver bit is arranged at one end of the screwdriver rod, and the other end of the screwdriver rod is arranged in the center of the screwdriver handle and extends into the screwdriver handle. The compression spring, the intra-handle movable piece, the first tooth-shaped part, the second tooth-shaped part and the nut are arranged in the screwdriver handle from the position close to the screwdriver bit. One end of the compression spring makes contact with the inner wall of the screwdriver handle, and the other end of the compression spring is fixed in the intra-handle movable piece. The first tooth-shaped part is arranged on the intra-handle movable piece. The second tooth-shaped part is arranged at one end of the nut, tightly meshed with the first tooth-shaped part and matched with the first tooth-shaped part in shape. The structural design of all the components of the medical torque screwdriver is ingenious, miniaturization design and usage are achieved, structure realization is easy, the number of components and parts is small, machining is easy, and the cost is low.
Description
technical field [0001] The invention belongs to the field of medical instruments, in particular to a medical torque screwdriver. Background technique [0002] Torque screwdrivers are used to lock screws or fasteners when they encounter large torques that may cause damage to the fastened parts. The screwdriver will automatically slip or dislocate, or at the same time make a very obvious sound to remind the user to achieve safety. A screwdriver with a special function for locking. At the same time, when loosening screws or fasteners, the screws can be easily loosened without slipping or dislocation. [0003] In the medical field, especially in the operation process, the torque screwdriver is used for screw locking key medical components without damaging the medical components, and at the same time can easily loosen the screw fasteners to achieve the purpose of surgery. [0004] The existing medical torque screwdrivers are divided into two types: one is electric type, which r...
