Patent number: 7306592Abstract: An bipolar electrosurgical tool (10) for cauterizing or ablating tissue. The tool has a nose cone (12) which serves as a handle. A conductive shaft (14) extends from the nose cone. A tip assembly (18) with an active electrode (20) is mounted to the shaft. A circuit board (78) is mounted in the nose cone. Conductive traces that forming contact pads (96, 102) are formed on the circuit board. A web (108) formed from a single piece of elastomeric material is seated over the opening in which the printed circuit board is mounted to seal the opening shut. Integrally formed with the web are buttons (116, 118) that are in registration over the contact pads. The buttons can be depressed downwardly towards the contact pads. When a button is so depressed, a conductive landing pad (120) integral with the button closes the connection between the traces that form the contact pad. Thus, the tool of this invention is provided with switches. The circuit board also has two conductive traces (92, 104a) that run in parallel.Type: GrantFiled: August 26, 2002Date of Patent: December 11, 2007Assignee: Stryker CorporationInventors: Roy Morgan, Heber Saravia, Jens Voges, Mani Prakash

Patent number: 6602221Abstract: A fluid management pump system (20) for applying an irrigation/distention solution to a surgical site. The system includes a pump (22) for forcing the solution through an inflow tube (28). A portable power pack (26) attached to the pup provides the energization current for actuating the pump. The solution is introduced into the surgical site from the inflow tube through a first cannula (30) across which there is a relatively small pressure drop. Fluid discharged from the surgical site is drained from the site through a second cannula (32) across which there is a low pressure drop. A hand controller (38) is attached to the inflow and outflow tubes. The hand controller contains a valve (46) for regulating fluid flow through the outflow tube. A pump control circuit (232) is also disposed in the hand controller.Type: GrantFiled: July 3, 2000Date of Patent: August 5, 2003Assignee: Stryker CorporationInventors: Heber Saravia, Jens Voges
