  • Self-cleaning holster for electrocautery tip
    Patent number: 6367110
    Abstract: A self-cleaning holster for holding an electrosurgical instrument and for cleaning a blade secured to the electrosurgical instrument is provided. The holster has a portion for securely supporting the holder portion of the instrument, as well as a portion for securely supporting and cleaning the blade. A separate blade-cleaning portion is provided for cleaning the blade during surgery.

  • Gold-plated electrosurgical instrument
    Patent number: 5885281
    Abstract: An electrosurgical instrument and method for making and using the same are provided. The electrosurgical instrument includes a stainless steel blade having two major opposed surfaces connected by two edge surfaces, with each surface plated with an intermediate layer comprising a substantially non-toxic metal having a hardness of at least about 130 on a Knoop scale and an electrical resistivity not exceeding about 15 microhm-cm at 20.degree. C. A non-stick coating is coated on the intermediate layer on only the two major opposed surfaces, thereby exposing the intermediate layer on the two edge surfaces. The non-stick coating prevents tissue from sticking to the instrument during surgery while the intermediate metal layer enhances the electrical conductivity of the instrument for more efficient cutting and cauterization of tissue with less power consumption.

  • Gold-plated electrosurgical instrument
    Patent number: 5643256
    Abstract: An electrosurgical instrument and method for making and using the same is provided. The electrosurgical instrument includes a stainless steel blade whose surface is plated with an intermediate layer comprising a substantially non-toxic metal having a hardness of at least about 130 on a Knoop scale and an electrical resistivity not exceeding about 15 microhm-cm at 20.degree. C., with the intermediate layer having a non-stick coating. The non-stick coating prevents tissue from sticking to the instrument during surgery while the intermediate metal layer enhances the electrical conductivity of the instrument for more efficient cauterization of tissue with less power consumption. The combination of an intermediate metal layer with an outer non-stick coating eliminates the need to choose between quick and efficient cauterization during surgery and the prevention of tissue sticking to the instrument.
