Non-stick bipolar forceps
View Patent ↗Disposable, bipolar electrosurgical forceps are designed to prevent the sticking of body tissue to the tips of the forceps and include a pair of electrode arms having lengths with opposite proximal and distal ends, with thin layers of biocompatible metal on the forceps arm distal ends and bipolar electrical conductors permanently secured to the forceps arm proximal ends.
1. Disposable, tissue sticking resistant forceps comprising:
first and second elongate pincers consisting of aluminum, each pincer having an intermediate body portion that is shaped and dimensioned to be held in a single hand, and each pincer having a proximal end portion and a distal end portion at opposite ends of the pincer body portion, the pincer proximal end portions being secured together, and the pincer distal end portions extending from the body portions to pointed end tips of the pincers;
an electrically conductive cord permanently connected to the proximal end portion of at least one pincer, the cord having a flexible length that extends from the at least one pincer to an electrical connector on an opposite end of the cord from the at least one pincer; and,
a layer of biocompatible metal on the aluminum of each pincer at only the pointed end tip, each layer of biocompatible metal consisting of a pure metal, each layer of biocompatible metal having a thickness that is less than 0.010 of an inch, thereby enabling the forceps to be disposable.
2. The forceps of claim 1 , further comprising:
the thickness of the layer of biocompatible metal on each pincer pointed end tip being in a range of 0.0005 of an inch to 0.005 of an inch.
3. The forceps of claim 2 , further comprising:
the biocompatible metal being pure silver.
4. The forceps of claim 2 , further comprising:
the biocompatible metal being pure gold.
5. The forceps of claim 1 , further comprising:
electrically insulating coatings over the intermediate body portions of the first and second pincers with the proximal end portions and the distal end portions of the first and second pincers being exposed from the coatings.
6. The forceps of claim 5 , further comprising:
the electrically conductive cord being one cord of a pair of first and second electrically conductive cords having elongate, flexible lengths with opposite proximal and distal ends, the distal ends of the first and second cords being permanently secured to the respective proximal end portions of the first and second pincers and the proximal ends of the first and second cords having electrical connectors thereon.
7. The forceps of claim 6 , further comprising:
a base of electrically insulating material encapsulating the proximal end portions of the first and second pincers and the distal ends of the first and second cords.
8. The forceps of claim 1 , further comprising:
the layer of biocompatible metal on each pincer pointed end tip being not more than 0.005 of an inch.
9. Disposable, tissue sticking resistant forceps comprising:
first and second elongate pincers consisting of aluminum, each pincer having an intermediate body portion that is shaped and dimensioned to be held in a single hand, and each pincer having a proximal end portion and a distal end portion at opposite ends of the pincer body portion, the pincer proximal end portions being secured together;
first and second electrically conductive cords permanently secured to the proximal end portions of the respective first and second pincers, the first and second cords each having flexible lengths that extend from the first and second pincers to first and second electrical connectors on the respective first and second cords; and,
first and second tips on the distal end portions of the respective first and second pincers, each of the first and second tips consisting of a layer of a biocompatible metal on the aluminum at only the first and second tips of the pincers, where the layer of biocompatible metal has a thickness that is not more than 0.010 inches.
10. The forceps of claim 9 , further comprising:
the thickness of the layer of biocompatible metal of each tip being in a range of 0.002 of an inch to 0.005 of an inch.
11. The forceps of claim 9 , further comprising:
the biocompatible metal being pure silver.
12. The forceps of claim 9 , further comprising:
the biocompatible metal being pure gold.
13. The forceps of claim 9 , further comprising:
electrically insulating coatings over the intermediate body portions of the first and second pincers with the proximal end portions and the distal end portions of the first and second pincers being exposed from the coatings.
14. The forceps of claim 9 , further comprising:
a base of electrically insulating material encapsulating the proximal end portions of the first and second pincers and the proximal ends of the first and second cords.
15. Disposable, tissue sticking resistant forceps comprising:
first and second elongate pincers consisting of aluminum, each pincer having an intermediate body portion that is shaped and dimensioned to be held in a single hand, and each pincer having a proximal end portion and a distal end portion at opposite ends of the pincer body portion;
coatings of electrically insulating material over the intermediate body portions of the first and second pincers;
a first electrically conductive cord connected to the proximal end portion of the first pincer;
a second electrically conductive cord connected to the proximal end of the second pincer;
a base of electrically insulating material encapsulating the proximal end portions of the first and second pincers and encapsulating portions of the first and second cords connected to the respective first and second pincers; and,
first and second layers consisting of biocompatible metal on the aluminum of only the distal end portions of the respective first and second pincers, the first and second layers of metal each having a thickness on the aluminum of the distal end portions of the respective first and second pincers of not more than 0.010 of an inch.
16. The forceps of claim 15 , further comprising:
the first and second electrically conductive cords being bipolar cords that are permanently connected to the respective first and second pincers, the bipolar cords having flexible elongate lengths that extend from the pincers to electrical connectors at opposite ends of the cords lengths from the pincers.
17. The forceps of claim 16 , further comprising:
the thickness of the layer of biocompatible material on each pincer tip being in a range of 0.002 of an inch to 0.005 of an inch.
