Abstract

The present disclosure relates to an apparatus and method for preventing reuse of a surgical instrument. The single-use surgical instrument includes a housing, an electrical connector and a treatment component. Indicia may be printed on the housing, the electrical connector and/or the treatment component. A removable ink is applied to any portion of the surgical instrument in the form of indicia that is readable by a scanning device. The removable ink includes a protein-based composition that is reactivateable with a sterilization solution having an enzyme-based composition such that upon sterilization, the removable ink reacts with the sterilizing solution and becomes unreadable by the scanning device.

Claims (14)

1. A method for preventing reuse of a surgical instrument, comprising:

applying a removable ink to at least one portion of the surgical instrument in a readable fashion, the removable ink including a protein-based composition reactivateable with a sterilization solution having an enzyme-based composition;

electrically coupling a scanning device to an electrosurgical energy source; and

validating the surgical instrument for an initial use by reading the removable ink applied to the surgical instrument with the scanning device.

2. The method for preventing reuse of a surgical instrument according to claim 1 further comprising:

at least partially dissolving the removable ink when the surgical instrument is placed in contact with a sterilization solution to render the removable ink unreadable.

3. The method for preventing reuse of a surgical instrument according to claim 1 further comprising configuring the removable ink in the form of at least one of a one-dimensional code, a two-dimensional code, and a three-dimensional code.

4. The method for preventing reuse of a surgical instrument according to claim 1 wherein applying the removable ink to at least a portion of the surgical instrument includes applying the removable ink to at least one of a connector, a shaft, a housing, an end effector, a handle, an actuator, a rotation mechanism, an articulation mechanism, and a switch.

5. The method for preventing reuse of a surgical instrument according to claim 1 further comprising disposing the removable ink on a label and securing the label to the surgical instrument.

6. The method for preventing reuse of a surgical instrument according to claim 1 further comprising disposing a liner atop the removable ink to protect the removable ink.

7. The method of preventing reuse of a surgical instrument according to claim 1 further comprising:

using the surgical instrument;

sterilizing the surgical instrument; and

attempting to validate the surgical instrument for re-use by scanning the removable ink with the scanning device.
