Abstract
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.
