Filed:

Oct 29, 2001

Appl. No.:

10/036021

Inventors:

Jerry A. Culp - Oshtemo Township, Kalamazoo County MI
Kevin J. Schemansky - Farmington Hills MI
David E. Monk - Portage MI

Assignee:

Stryker Corporation - Kalamazoo MI

International Classification:

A61B 1732

US Classification:

606170, 79180

Abstract:

A surgical tool system ( ) with a powered surgical handpiece ( ). A removable handswitch ( ) is attached to the handpiece. The handswitch includes a slip ring ( ) that removably holds the handswitch to the handpiece. A lever arm ( ) is pivotally attached to the slip ring. A magnet ( ) 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 ( ) 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.

Stryker Corporation - Kalamazoo MI

International Classification:

A61B 17/32

US Classification:

606170

Abstract:

A surgical tool system including a handpiece with a power generating unit and a control console for supplying energization signals to the power generating unit. Based on the data in a memory associated with the handpiece, the control console supplies energization signals to the handpiece power generating unit in either a motor drive mode or a direct drive mode. In the motor drive mode the signals are supplied to windings integral with the power generating unit based on the position of a rotor also part of the power generating unit. In the direct drive mode, energizaiton signals are supplied to the power generating unit independent of rotor position.

Jerry A. Culp - Oshtemo Township MI, US
Kevin J. Schemansky - Madison Heights MI, US
David E. Monk - Portage MI, US

International Classification:

H01H 3/04

US Classification:

200335

Abstract:

A hand switch for removable attachment to a powered surgical tool. The switch includes a ring formed with a slot that is snap fit over the tool with which the switch is used. A manually actuatable lever is pivotally mounted to the ring. Internal to the lever is a magnet. The position of the magnet is monitored by a sensor internal to the tool. A tab extends inwardly from the ring. The tab seats in a notch integral with the tool. The seating of the tab in the notch aligned the switch with the sensor internal to the tool.

International Classification:

H02P 700
A61B 1700

US Classification:

318434

Abstract:

An integrated surgical tool system (30) for energizing different powered surgical handpieces (32, 33). Internal to each handpiece is a non-volatile memory (72) which stores data regarding the operating parameters of the handpiece. This data, includes information about the speeds at which any motor internal to the handpiece should be driven, the maximum current that should be drawn by the handpiece and the maximum internal temperature of the handpiece. The handpiece is plugged into a complementary control console (36). The control console reads the data in the internal memory. Based on the retrieved data and manual control signals, the control console supplies energization signals to the handpiece so as to cause the appropriate actuation of the handpiece.
