Surgical system for powered instruments
First Claim
1. A surgical system adapted to operate a set of different surgical devices having different operational limits, comprising:
- a handpiece adapted to alternately receive a proximal portion of each of said surgical devices,said set of said surgical devices,each of said surgical devices having an indicator on its proximal portion that denotes its operational limit,said handpiece including automatic sensor means for sensing said indicator;
a motor for driving said handpiece; and
means responsive to said sensor to automatically establish the operational limit of said motor in accordance with the respective surgical device received by said handpiece.

Abstract
A single-motor surgical system for operating a set of different surgical devices having different operational limits, consisting of a handpiece containing the motor and adapted to alternately receive a proximal portion of each of the surgical devices, each device having an indicator on its proximal portion that denotes its operational limit, the handpiece including an automatic sensor for sensing the indicator, and controls responsive to the sensor to automatically establish the operational limit of the motor in accordance with the respective surgical device received by the handpiece. In preferred embodiments, the system includes an arthroscopic handpiece as above and has a plurality of surgical devices adapted to receive different removable rotary tips that have different operational limits of rotation, each of the plurality of devices having a vacuum passage connectible at one end to a vacuum passage of the respective rotary tip and adjacent the other end, to a vacuum passage associated with the handpiece, whereby tissue severed by the rotary tip can be removed from the surgical site, the surgical device indicating to the sensor the rotational limits of the tips which the devices are adapted to receive.

10. An arthroscopic handpiece for use in a surgical system comprising said handpiece, a set of surgical devices having different operational limits, each surgical device having on its proximal portion an indicator means for denoting its operational limit, and a motor for driving said handpiece;
-
said handpiece comprising automatic sensor means adapted for sensing one of said indicator means denoting the operational limit of a respective surgical device received by said handpiece, said arthroscopic handpiece having means adapted to alternatively receive a proximal portion of said surgical device of the set for operation of the surgical device at its indicated operational limit, and said handpiece also comprising rotation means for rotating a member within the handpiece wherein said member has means adapted to be associated with a respective surgical device, said rotation means adapted to be driven by said motor, said handpiece further comprising means responsive to said automatic sensor means for controlling said rotation means, thereby establishing the operational limit, and said handpiece adapted for operation of a surgical device comprising, at its distal portion, a rotary tip that has an operational limit of rotation indicated by that surgical device, each surgical device defining a vacuum passage connectible at one end to a vacuum passage of a respective rotary tip, said arthroscopic handpiece defining a vacuum passage having means adapted for connection to the vacuum passage of the surgical device and for connection proximally to a source of vacuum for removal of tissue severed by operation of the rotary tip from the surgical site through the vacuum passage of said handpiece.
