摘要:
A keel punch impactor comprises a main body having an interior bore. A locking shaft is positioned in the interior bore of the main body, the locking shaft defining a shaft axis. An actuator is in contact with the locking shaft. The actuator is moveable between a first position and a second position. The position of the locking shaft is moved within the interior bore of the main body upon movement of the actuator. In particular, the locking shaft is moved such that the shaft axis is offset when the actuator is moved from the first position to the second position. When the shaft is moved, a head on the shaft is moved into or out of alignment with a boss extending from the main body of the keel punch impactor.

A self-centering coupling device is provided for coupling a sensor array to a surgical instrument for use in computer guided surgery. The self-centering coupling device includes a sensor support having a stem and sensor support arms coupled to the stem to support the sensors of the sensor array. The self-centering coupling device is received within a recess formed in the surgical instrument.

A finely-adjustable resection guide has two bodies pivotally connected to each other. One of the bodies has a plurality of threaded through-bores extending in perpendicular directions through the body. Two thumbscrews extend through the threaded through-bores. The thumbscrews can translate linearly with respect to the body as they are turned. A cutting block is pivotally connected to the body that has the thumbscrews. Linear translation of one of the thumbscrews causes the cutting guide surface of the cutting block to pivot about one axis and linear translation of the other thumbscrew causes the cutting guide surface to pivot about another axis that is perpendicular to the first axis. A third threaded member is provided to adjust the proximal-distal position of the cutting guide surface.

An acetabular reamer is provided. The acetabular reamer includes a body having a peripheral surface. The peripheral surface is defined by a radius extending from an origin. The body defines an axis of rotation of the body. The body defines an end surface operably connected to peripheral surface of the body. The body further defines a relief surface spaced from the axis of rotation and operably connected to peripheral surface. The acetabular reamer also includes a cutter operably associated with the body for reaming a portion of the acetabulum and a support structure secured to the relief surface.

摘要:
A system and method for controlling a centrifuge which receives a mixture of liquid and solid particles and separates the liquid from the solid particles. A bowl, along with a conveyor extending inside the bowl, are rotated and the speed of, and the torque applied to, the bowl and the conveyor are detected and corresponding output signals are generated. A variable speed drive pump is provided for pumping the flow of the mixture to the centrifuge. A computer responds to the output signals and controls the speed of the bowl and the conveyor as well as the operation of the pump to attain predetermined optimum operating conditions of the centrifuge.

A system, method and computer program for controlling a centrifuge which receives a mixture of liquid and solid particles and separates the liquid from the solid particles. A bowl, along with a conveyor extending inside the bowl, are rotated at different speeds and the speed of, and the torque applied to, the bowl and the conveyor are detected and corresponding output signals are generated. A meter is provided for metering the flow of the mixture to the centrifuge and generating corresponding output signals. A computer responds to instructions from computer programs and controls the speed of the bowl and the conveyor as well as the flow of the mixture and a diluting agent to the centrifuge in response to the output signals in a manner to attain predetermined predetermined optimum operating conditions of the centrifuge.
