Abstract

The invention belongs to the technical field of orthopaedic surgical equipment, and discloses a pen-type hand-pressed fine bone drill for orthopaedic surgery, wherein the pen-type hand-pressed fine bone drill for orthopaedic surgery is provided with a shell. A transmission rod, a miniature gearbox, a motor and a storage battery are sequentially arranged from the front end to the rear end inside the shell; A drill bit is arranged in front of the shell; A transmission rod is arranged behind the drill bit, and the front end of the transmission rod is connected with the drill bit through a coupling; The transmission rod is connected with a micro transmission through a coupling; The micro-gearbox is connected with an electric motor through a coupling; A motor switch and a speed regulating button are arranged on the outside of the housing, and a fixing bracket is fixed on the front screw. The bone drill realizes the speed regulating function of the fine bone drill when in use. A switch of that motor is arranged at the position of the index finger, which is convenient to operate; meanwhile, the invention has the advantage of simple structure, strong structure and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of orthopedic surgery equipment, in particular to a pen-type hand-pressed fine bone drill for orthopedic surgery. Background technique [0002] At present, open fractures in children are mostly caused by high-energy external force, which will cause serious complications and developmental sequelae if not treated in time. In the traditional children's fracture surgery, adult surgical instruments are mostly used for surgery. However, adult surgical instruments have the disadvantages of large volume and heavy weight, which do not meet the needs of children's small fracture surgery, and will cause some inconvenience to medical staff in the operation. In addition, the traditional bone drill does not have the function of speed regulation, so it has great limitations in use. [0003] Brushless DC motor is a new type of speed-regulating motor developed with the development of power electronics technology and microel...
