Hand-held surgical devices
First Claim
1. A surgical system for performing a surgical procedure, the surgical system comprising:
- an intelligent surgical device includes;
a housing;
a power source supported in the housing;
at least one drive motor supported in the housing and being in electrical communication with the power source; and
control circuitry interfacing with the power source and the at least one drive motor, wherein the control circuitry includes a feedback system for monitoring at least one condition of the surgical device during a use thereof and for changing an operative parameter of the surgical device when a change in the at least one monitored condition occurs, wherein the feedback system includes a resistor of a known quantity associated with a voltage being delivered to the at least one drive motor, and wherein the feedback system calculates a current level across the resistor; and
at least one non-intelligent loading unit configured for selective connection to the housing of the surgical device and which is actuatable by the at least one drive motor, the loading unit having at least a first condition and a second condition,wherein, during operation of the surgical device, the at least one drive motor actuates the loading unit from the first condition to at least the second condition;
wherein, when the loading unit achieves the second condition, a change in the at least one monitored condition occurs and an operative parameter of the surgical device is changed; and
wherein the at least one condition monitored by the feedback system is a voltage being delivered to the at least one drive motor.

Abstract
A surgical system is provided and includes an intelligent surgical device having a drive motor supported in the housing and being in electrical communication with the power source; and control circuitry. The control circuitry includes a feedback system for monitoring a condition of the surgical device during a use thereof and for changing an operative parameter of the surgical device when a change in the monitored condition occurs. The surgical system includes a non-intelligent loading unit for selective connection to the housing of the surgical device and which is actuatable by the drive motor, the loading unit having a first and a second condition. During operation, the drive motor actuates the loading unit from the first condition to the second condition; and when the loading unit achieves the second condition, a change in the at least one monitored condition occurs and an operative parameter of the surgical device is changed.
