Abstract

A medical device with an operating element for triggering the medical device is disclosed. The medical device includes a safety system for preventing an erroneous triggering of the device. The safety system further includes an identification device and a securing mechanism.

Claims

1. A safety system for use with a medical device comprising:

a medical device operating element; and

a safety mechanism operably coupled to said medical device operating element for preventing erroneous actuation of said medical device operating element by requiring user-specific authorization data;

wherein said safety mechanism comprises;

an identification device for receiving user-specific identification data;

wherein the identification device stores user-specific authorization data having associated user-specific identification data, correlates received user-specific identification data with said stored user-specific authorization data having user-specific identification data, and sends said user-specific authorization data to a securing mechanism upon selected correlation of said received and stored user-specific identification data; and

said securing mechanism providing a plurality of securing levels, wherein each of said plurality of securing levels is releasable in response to receiving user-specific authorization data associated with one or more of said plurality of securing levels, release of said one or more of said securing levels providing a secure level of operation of said medical device operating element.
