The invention provides a medical micro-power torsion screwdriver which comprises a screwdriver
handle, a screwdriver rod, a coaxial mutually-clamped sleeve and a
micro motor; a front end cover and a rear end cover are arranged at the front end and the rear end of the screwdriver
handle respectively, a front end inserting opening is formed in the front end cover, the coaxial mutually-clamped sleeve and the
micro motor are both located in the screwdriver
handle, A spring is arranged between the coaxial mutually- clamped sleeve and the inner wall of the front end cover, the screwdriver rod penetrates through the front end inserting opening and an inner ring of the spring to be connected with one end of the coaxial mutual clamping sleeve, and the other end of the coaxial mutually-clamped sleeve is connected with the
micro motor. By adopting a micro motor and a torsion
control system, the problem of excessive physical labor caused by holding a handheld electric
drill for a long time by
medical staff is solved, and the
adverse conditions of screw
tail slipping and
cold welding are avoided; a bit sleeve or an electric
drill chuck is adopted, the medical micro-power torsion screwdriver is compatible with bits of different sizes, torsion is adjustable, the adaptability is high, bacterial
contamination is obviously reduced compared with a common electric
drill, andthe medical micro-power torsion screwdriver is very suitable for hospitals and
medical staff.
