During an arthroscopic procedure, the damaged joint must be distended to allow for close inspection, increased surgical space and decreased bleeding during the operation. To achieve distension, fluid under continuous pressure is introduced into the joint through a cannula system. Joint distention is maintained by a fluid management system that can either be gravity or pump controlled.
Gravity is the simplest form of fluid management and consists of a liquid that is administered through a bag reservoir that is raised above the patient.
The full report suite on the U.S. market for arthroscopic devices includes arthroscopes, disposable cannulas, hand instruments, fluid management disposables, shaver blades, radiofrequency (RF) probes, drill guide systems and disposables and suture passers. Power instruments are covered in an appendix.
