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

1. A single-use surgical instrument system, comprising:

a scanning device configured to read a removable ink; and

a surgical instrument, comprising;

a housing, an electrical connector, and a treatment component, wherein at least one of the housing, the electrical connector, and the treatment component is configured to accept indicia printed thereon, at least one portion of the surgical instrument supporting the removable ink in the form of indicia readable by the scanning device, the removable ink including a protein-based composition reactivateable with a sterilization solution having an enzyme-based composition such that upon a sterilization of the instrument with the solution, the removable ink reacts only with the sterilization solution and becomes unreadable by the scanning device, the removable ink disposed on a label secured to the surgical instrument, wherein the label is secured to the surgical instrument with an adhesive, the adhesive being dissolvable with the sterilization solution having the enzyme-based composition, facilitating detachment of the label from the surgical instrument.

2. The single-use surgical instrument system according to claim 1, wherein the removable ink, the label, and the adhesive are indissolvable when exposed to water, saline, blood, or other fluids commonly associated with a surgical environment.

3. A single-use surgical instrument system, comprising:

a scanning device configured to read a removable ink; and

a surgical instrument, comprising;

a housing, an electrical connector, and a treatment component, wherein at least one of the housing, the electrical connector, and the treatment component is configured to accept indicia printed thereon, at least one portion of the surgical instrument supporting the removable ink in the form of indicia readable by the scanning device, the removable ink including a protein-based composition reactivateable with a sterilization solution having an enzyme-based composition such that upon a sterilization of the instrument with the solution, the removable ink reacts only with the sterilization solution and becomes unreadable by the scanning device, the removable ink disposed on a label secured to the surgical instrument, the label secured to the surgical instrument with an adhesive, the adhesive being dissolvable with the sterilization solution having the enzyme-based composition to point “

x”

, the label detaching from the surgical instrument upon exposure to the protein-based enzyme to point “

x.”
