3.2 Using the Arthroscopy Indication
Intended use: ArthroscopyThe devices PG130/PG145 may be used for the distention and irrigation of knee,
shoulder, hip, elbow, ankle and wrist joint cavities during diagnostic and surgical
procedures such as:
• Ligament injuries
• Meniscus injuries
•Cartilage injuries
• Surgical plans and follow-up exams
The user can preset the desired joint pressure.
The pump attempts to reach and maintain the preset pressure in the joint by sup-
plying irrigation fluid. If the joint cannot be drained (e.g., because closed valve at
instrument), and if the preset pressure has been reached, the pump reduces the
influx of fluid and attempts to maintain the preset pressure. If the intra-articular
pressure falls below the selected value, fluid automatically continues to be sup-
plied.
ContraindicationsUse of these devices to inject fluid into a joint is prohibited whenever arthroscopy
is contraindicated.
Arthroscopy is contraindicated in the following cases:
• Ankylosis (anchylosis)
• Inflammation or bacterial contamination
The devices may not be used to inject medication.
The devices are not designed or suitable for use with gas.
Recommended pressureThe preset pressure should be based on the average blood pressure of the patient
to prevent bleeding in the joint. The manufacturer recommends the following
pressure settings for the following application areas:
Each surgery and each patient require different parameters. The values indicated
by the manufacturer are therefore only recommendations and are not intended
to substitute or replace the expertise of the surgeon.
Technical application scope: ArthroscopyThe following characteristics apply to the arthroscopy indication:
• The nominal pressure can be preset to a range of 15 to 200 mmHg.
• The nominal flow can be preset to a range of 0.1 to 2.5 l/min.
• The devices feature an instrument recognition function.
• To improve visibility within a joint, the devices are equipped with a "Wash"
function.
• The devices have an optional suction function with 2 settings for shavers.
• The pump reacts to pressures greater than the set nominal pressure by emit-
ting warnings. The devices have safety thresholds.
Clinical useWhen performing monopolar electrosurgery, only non-conductive irrigation flu-
ids may be used. Examples include glycine, sorbitol, mannitol, sorbitol plus man-
nitol, and dextran.
Knee joint 70 mmHg
Shoulder joint 60 mmHg
Hip joint 60 mmHg
Elbow joint 50 mmHg
Ankle joint 70 mmHg
Wrist joint 60 mmHg
