A manual and automatic fluid control system and method for use in open and laparoscopic laser surgery and electrosurgery is disclosed. The system includes a manual mode along with several automatic modes which can effectuate both suction and irrigation, either individually or simultaneously. In the various automatic modes, the suction and/or irrigation is automatically activated during activation of a medical apparatus for laser surgery or electrosurgery without requiring separate activation from the surgeon or operating room staff. Several safety features for monitoring the fluid control system are also incorporated within the system such as fluid sensors for detecting the absence of irrigation fluid, pressure sensors and vacuum systems for monitoring fluid pressure, fluid sensors for monitoring fluid volume, and warning signals for detecting empty containers. All of the safety features are designed to automatically deactivate suction and/or irrigation means contained within the fluid control system upon detection of unsafe levels. Finally, specially designed suction/irrigation hand pieces are disclosed for use in connection with the fluid control system.

1. A multifunctional handpiece for performing suction and irrigation comprising: an elongated hollow member comprising an outer annular channel and an inner central channel disposed axially within said outer annular channel; and a suction/irrigation adaptor connected to said elongated hollow member, said suction/irrigation adaptor having a suction port and an irrigation port wherein said outer annular channel of said elongated hollow member is in fluid communication with said suction port and said inner central channel of said elongated hollow member is in fluid communication with said irrigation port. 2. The multifunctional handpiece of claim 1, further comprising: a handpiece member connected to said suction/irrigation adaptor, said handpiece member having electrical contacts for activating a suction device and an irrigation device. 3. The multifunctional handpiece of claim 1, further comprising an electrosurgical connector connected to said suction/irrigation adaptor, said electrosurgical connector comprising an electrode which extends from said electrosurgical connector through said suction/irrigation adaptor and said elongated hollow member and extends beyond said elongated hollow member, said electrode being in electrical communication with an electrosurgical generator. 4. The multifunctional handpiece of claim 3, said electrosurgical connector further comprising a first member fixedly attached to said electrode and a second member disposed annularly around said first member, said first member being slidably received within said second member such that said first member may be moved from a first position relative to said second member to a second position relative to said second member, wherein said electrode can be retracted into said elongated hollow member by moving said first member from said first position to said second position. 5. A multifunctional handpiece for performing suction and irrigation in conjunction with electrosurgery and laparoscopy comprising: a suction/irrigation adaptor having a suction port and an irrigation port; an elongated hollow member comprising an outer annular channel and an inner central channel disposed within said outer annular channel, said outer annular channel being in fluid communication with said suction port and said inner central channel being in fluid communication with said irrigation port; and a handpiece member connected to said suction/irrigation adaptor, said handpiece member having electrical contacts for activating a suction device and an irrigation device. 6. The multifunctional handpiece of claim 5, further comprising an electrosurgical connector connected to said suction/irrigation adaptor, said electrosurgical connector comprising an electrode which extends from said electrosurgical connector through said suction/irrigation adaptor and said inner central channel of said elongated hollow member, and extending beyond said elongated hollow member.
