ABSTRACT:
A handheld surgical instrument consists of a housing capable of being hand held and including a front end to which a surgical tool is mounted. The tool can be used for electrosurgery and includes a conduit for irrigating or evacuating an interior portion of the body of a patient. The instrument also includes a chamber for temporarily retaining irrigation fluid and from which the fluid can be supplied along the conduit to the body of the patient. Drive means mounted to the housing acts on the chamber to move fluid from the chamber along the conduit to the body of the patient. The instrument also includes a fluid supply for supplying irrigation fluid to the chamber. In operation, the drive means acts to alternately decrease and increase the volume of the chamber to alternately expel fluid from and draw fluid into it.
