Abstract
An electrosurgical electrode connector instrument for use in rapidly and easily connecting/disconnecting a disposable electrosurgical tip to and from a non-disposable mounting body. The non-disposable body includes a rod-like extension equipped with a pair of specially shaped projecting pins each having ramps and a curved surface. These pins are positioned on opposite sides of the rod-shaped extension. The disposable electrosurgical tip is provided at its proximal end with a tunnel-like recess having a pair of longitudinally disposed slots to define a pair of bifurcated cantilevered springy wall members each fitted with a small pin-locking aperture, thus adapting the disposable tip for telescopic engagement with the rod-like extension so that the recess of the disposable tip can be slid onto the rod-like extension with the specially shaped pins spreading the springy wall members slightly. After the tunnel-like recess has fully telescoped onto the aforementioned extension, the specially shaped pins snap into the pin-locking apertures to disengageably lock them in place. When it is desired to unlock the tip, the curved surfaces of the special geometrical characteristics of the pins m…
