Abstract
An electrosurgical apparatus includes two assemblies, one of which is the primary assembly intended for a first surgical procedure, such as cutting tissue, and a secondary assembly intended for a second type of electrosurgical procedure, such as tissue coagulation. The secondary assembly fits over the electrode tip of the primary assembly and makes electrical contact with the electrode tip of the primary assembly. This allows for single instrument surgery whereby the secondary (coagulation) assembly provides bleeding control after the primary assembly has cut tissue. This combination significantly reduces operating time. The secondary assembly has a snap fit over the primary assembly so that it may be readily attached and detached several times during any surgical procedure, as the surgeon alternates between cutting tissue and coagulating the resulting incisions using the apparatus.
