Powered surgical handpiece with removable control switch
First Claim
1. A powered surgical tool system, said system including:
- a powered handpiece for application to a body, said handpiece having a power consuming unit to which a select energization signals having a defined set of characteristics are applied and a non-volatile memory in which data regarding the characteristics of the energization signals that are applied to said handpiece are stored;
a control console configured to be connected to said handpiece for applying energization signals thereto and for reading data from said memory in said handpiece, said control console having;
a drive unit for generating the energization signals required by the handpiece, said drive unit being configured to generate the energization signals based on at least one drive unit command signal received thereby; and
a main controller connected to said memory in said handpiece and to said drive unit, said main controller being configured to retrieve the data stored in the memory in the handpiece and to generate said at least one drive unit command signal to said drive unit so as to control the generation of the energization signals by the drive unit in response to the data retrieved from the memory in the handpiece and an on/off signal; and
a manually actuatable switch connected to said main control console for generating said on/off signal and applying said on/off signal to said main controller of said control console.

Abstract
A surgical tool system (30) with a powered surgical handpiece (32). A removable handswitch (39) is attached to the handpiece. The handswitch includes a slip ring (192) that removably holds the handswitch to the handpiece. A lever arm (212) is pivotally attached to the slip ring. A magnet (190) is fitted in the lever arm. The angle of the lever arm is set by the surgeon to indicate the on/off state and operating speed of the handpiece. Internal to the handpiece is a sensor (94) that generates a signal based on the relative proximity of the magnet. The sensor signal is thus employed as the control signal for regulating the operation of the handpiece. Thus a surgeon can selectively use the handpiece with or without the mounted control switch.
