Definitions

  • ABSTRACT The invention relates to a small pneumatic motor for a Foreign Application Priority Data rotating medical instrument, especially for drilling or milling instruments.
  • a shaft with a turbine is sup- Oct. 28, 1969 Germany ..P 19 54 130.1 p e in a housing with the g inlet end of the bine arran ed towards the out ut end of the motor. 52 U.
  • the two stages of the turbine are arranged on a turbine rotor common to both stages, said stator being constructed in two stages in the form of two annular halves.
  • the stator After having pushed the two annular halves of the stator into a corresponding annular groove of the turbine rotor, the stator is fixed on its outer periphery inside the housing by means of correspondingly designed bushings. This is a very simple manner of fixing the stator, however, other constructions are not excluded.
  • a pneumatic turbine powered surgical motor apparatus for rotating a medical instrument comprising, in combination, an elongated housing having a longitudinal axis, an input end and an output end, a shaft rotatably mounted in said housing concentric with said axis and projecting from said output end adapted to drive a cutting instrument, a pressurized gas connection and an exhaust gas connection defined on said housing at said input end, an axial flow turbine having a rotor rotatably mounted in said housing concentric thereto and drivingly connected to said shaft, said turbine having an inlet disposed toward said housing output end and an exit disposed toward said housing input end, first passage means longitudinally defined in said housing concentrically extending about the periphery of said turbine and communicating with said pressurized gas connection and said turbine inlet, and second passage means defined in said housing communicating with said exhaust gas connection and said turbine exit whereby pressurized gas entering said pressurized gas connection and first passage flows toward said housing output end to said turbine inlet, enters said turbine inlet and reverses its direction of flow to flow through
