Abstract

The invention provides an endoscopic video camera having a polymeric knob assembly, wherein the polymeric material used for manufacturing the knob assembly includes polyphenylsulfone resin, titanium dioxide, tin oxide, and colored metallic additives, is capable of withstanding sterilization, and has a metallic cosmetic appearance. The invention also provides methods of manufacturing the knob assembly by plastic injection molding processes, wherein undesirable molding characteristics are concentrated on portions of the knob assembly that are removed by secondary machining or post machining.

First claim

What is claimed is:

1 . A polymeric material comprising from 0.1% to less than 1% mica, from 0.01% to 0.1% titanium dioxide, up to 0.01% tin oxide, from 0.02% to 0.2% colored metallic additives, and at least 99% polyphenylsulfone resin.

2 . The polymeric material of claim 1 wherein the colored metallic additives comprise from 0.01% to 0.1% solvent blue 104 and from 0.01% to 0.1% solvent violet 13 .

3 . A medical device component including a polymeric material, the polymeric material comprising from 0.1% to less than 1% mica, from 0.01% to 0.1% titanium dioxide, up to 0.01% tin oxide, from 0.02% to 0.2% colored metallic additives, and at least 99% polyphenylsulfone resin.

4 . The medical device component of claim 3 wherein the colored metallic additives comprise from 0.01% to 0.1% solvent blue 104 and from 0.01% to 0.1% solvent violet 13 .

5 . The medical device component of claim 3 wherein the polymeric material is over-molded over a metal body.

6 . A camera including at least one component formed at least partially from a polymeric material, the polymeric material comprising from 0.1% to less than 1% mica, from 0.01% to 0.1% titanium dioxide, up to 0.01% tin oxide, from 0.02% to 0.2% colored metallic additives, and at least 99% polyphenylsulfone resin.

7 . The camera of claim 6 wherein the colored metallic additives comprise from 0.01% to 0.1% solvent blue 104 and from 0.01% to 0.1% solvent violet 13 .

8 . The camera of claim 6 wherein the polymeric material is over-molded over a metal body.
