A system for performing a single portal diagnostic needle arthroscopy and lavage comprised of a handpiece having valves for irrigation and suctioning and a diagnostic cannula attached to the handpiece. An arthroscope is passed through the handpiece and the diagnostic cannula and allows the procedure to be performed through a single port of entry into the joint compartment. The system includes a mobile cart with a camera and light system and a high-resolution monitor. An air compressor is the pressure source powering the individually controlled irrigation pumps which drive the irrigation fluid through an irrigation hose to the handpiece while a vacuum suction console provides suction for collection of fluid in canisters mounted on the mobile cart. The system includes a biopsy cannula that can be easily exchanged for the diagnostic cannula using an exchange rod. The biopsy cannula is comprised of a pair of piggyback channels, one for visualization, diagnosis, irrigation and suction, while the other is for insertion of a biopsy instrument or other surgical devices. The biopsy instrument is comprised of a thin, approximately 1 mm flexible shaft connected to a forceps configured jaw at the distal end for performing surgical procedures in the joint compartment. A ring handle configuration at the proximal instruments end controls the jaws. Both the diagnostic cannula and biopsy cannula have couplings that include an auxiliary valve for introducing medication and drugs into the joint compartment as well as for removal of sterile synovial fluid.

1. A multi-function diagnostic needle arthroscopic and lavage system for diagnostic examination and treatment of joint diseases permitting entry, visualization, irrigation, suction, and biopsies through a single portal comprising;a handpiece having a central passageway; irrigation and suction channels connected to said handpiece; irrigation and suction trumpet valves in said handpiece for intermittent control of irrigation fluid and suctioning; a diagnostic cannula; a coupling for attaching said diagnostic cannula to said handpiece; a sharp trocar and blunt obturator for inserting said diagnostic or biopsy cannula and attached handpiece into said joint; a fiberoptic arthroscope for insertion through said handpiece and said diagnostic cannula after removal of said sharp trocar and blunt obturator for visualization of the joint compartment, examination, and diagnosis; said handpiece constructed for manipulating said diagnostic cannula in a joint compartment while alternately irrigating and suctioning by operation of said irrigation and suction trumpet valves; whereby said joint may be efficiently and conveniently examined, diagnosed, and treated through a single entry port.
