Abstract

A medical device including one or more components positioned to contact contaminants during use of the medical device. The one or more components including one or more limited-use portions transitionable upon use from an initial state, wherein the limited-use portion(s) exhibits a clean appearance, to a used state, wherein the limited-use portion(s) exhibits a contaminated appearance that visually indicates to a user that the at least one component is not further usable.

Claims (21)

1. A medical device, comprising:

at least one component configured to contact contaminants during use of the medical device; and

a first limited-use portion associated with the at least one component and configured to transition during use from a first state, wherein the first limited-use portion exhibits a clean appearance, to a second state, wherein the first limited-use portion exhibits a contaminated appearance that visually indicates to a user that the at least one component is not further usable, the first limited-use portion defining a cavity within the at least one component and including a transparent window covering a portion of the cavity to define an opening between the transparent window and an outer surface of the at least one component, the opening configured to allow passage of contaminants therethrough and into the cavity.

2. The medical device of claim 1 , wherein the at least one component is a jaw member of a forceps.

3. The medical device of claim 1 , wherein the at least one component is a disposable electrode assembly.

4. The medical device of claim 3 , wherein the disposable electrode assembly is configured to conduct electrosurgical energy to tissue.

5. The medical device of claim 1 , wherein the at least one component is a housing of an endoscopic medical device.

6. The medical device of claim 1 , further comprising a second limited-use portion associated with the at least one component.

7. The medical device of claim 6 , wherein the second limited-use portion includes a plurality of grooves configured to trap bodily fluids and tissue remnants.

8. The medical device of claim 1 , further comprising a second limited-use portion having a color change material associated with the at least one component and configured to transition during use from a first state, wherein the second limited-use portion exhibits a first appearance, to a second state, wherein the second limited-use portion exhibits a second appearance that visually indicates to a user that the at least one component is not further usable.

9. The medical device of claim 8 , wherein the color change material is configured to change color upon making contact with at least one of blood, tissue, or fluids.

10. The medical device of claim 8 , wherein the color change material is temperature-sensitive such that the color change material changes color in response to a change in temperature.

11. The medical device of claim 1 , wherein the transparent window is configured to prevent passage of fluids therethrough.

12. A method, comprising:

providing a medical device including at least one component;

using the medical device to perform a surgical task, wherein, during use of the medical device, a first limited-use portion associated with the at least one component comes into contact with contaminants such that the contaminants are captured within a cavity defined within the at least one component; and

viewing the contaminants captured within the cavity through a transparent window that partially covers the cavity thereby alerting a user that the at least one component is not further usable after use of the medical device,

wherein an opening is defined between the transparent window and an outer surface of the at least one component, and wherein the contaminants move into the cavity via the opening.

13. The method of claim 12 , further comprising capturing the contaminants within a plurality of grooves defined in the at least one component, wherein the plurality of grooves is configured to trap bodily fluids and tissue remnants.

14. The method of claim 12 , further comprising changing a color of a second limited-use portion associated with the at least one component by contacting the second limited-use portion with the contaminants.

15. The method of claim 12 , wherein the transparent window is configured to prevent passage of fluids therethrough.
