A system used during endoscopic orthopedic procedures to expand the joint, improving visibility and enlarging the surgical field. The irrigation/distention system pumps solution into the joint, keeping it filled with pressurized distention solution. The solution may be held in place by a manual stopcock, or an automated pinch valve.
1. When choosing an arthroscopic pump, the main selection factor should be the ability of the device to adequately keep pressures at appropriate levels.
2. The surgeon should be the one to choose the arthroscopic pump type. Surgeons need to decide between the greater control provided by volumetric pumps, which provide greater control, and gravity-assisted units, which provide effective air-infusion protection.
3. Facilities should also consider the cost and the efficiency issues involved. They should avoid arthroscopic irrigation distention systems that offer more sophistication than is required by the types of procedures being performed.
4. An arthroscopic pump that can cause or allow a joint to become over-pressured, can put patients at a higher risk for extravasations, which are the most common significant complications linked to use of these devices.
5. The arthroscopic pump should monitor actual joint pressures and maintain these within 10 mm Hg or within 20% of the set pressure (whichever is greater). 6. The arthroscopic pump will not be able to generate sustained pressures that are greater than 180 mm Hg and relieve pressures greater than 250 mm Hg.
7. For safety purposes, arthroscopic pumps should include gauges that clearly and accurately display joint pressure, as well as a means of preventing the infusion of air.
8. Clear audible and visual alarms should inform the user of an over pressurization.
9. There are some benefits to arthroscopic irrigation systems that can control solution outflow from the joint.They allow the surgeon to adjust pressure and they flow more precisely than those that control only inflow.
10. Some arthroscopic irrigation distention systems allow continuous flow through the joint. This usually consumes more distention solution during the procedure and requires changing solution bags more frequently. Also the added tubing can complicate the setup, use, and maintenance of such a system.
11. Some arthroscopic irrigation systems can pump the air trapped in irrigation solution bags into the joint, causing bubbles large enough to interfere with visibility.
12. Peristaltic-driven systems are better at pressure maintenance and are preferable to impellers.
