ELECTRIC BURNING NEEDLE AND PRODUCTION THEREOF

Title:

ELECTRIC BURNING NEEDLE AND PRODUCTION THEREOF

Document Type and Number:

Japanese Patent JPS57211344

Kind Code:

A

Abstract:

A disposable electrocautery needle which may be used either in the bi-polar or mono-polar mode comprises an elongate inner electrode (12) located within a hollow outer elongate electrode (14) and held in place by means of a hollow insulating element located between them. The needle may be formed by locating the insulating element over the inner electrode, stretching it axially to reduce its diameter, positioning the inner electrode (12) and insulating element within the outer electrode (14) and causing the insulating element to recover to its unstretched configuration, for example by heat in the case of a heat-recoverable element, and position in the inner electrode (12) correctly within the outer electrode (14).
