Arthrocentesis Model

Practice diagnosing and managing the presence of an effusion with this anatomically correct arthrocentesis model. The trainer represents an extended left leg with ultrasound compatible areas, including: the patella, patella ligament, tibia, fibula, femur, synovial sac, and synovial fluid. Synovial fluid can be aspirated from a joint cavity using the medial or lateral approach. And insertion sites include suprapatellar and parapatellar.

Description

Skill Development

Learn to ballot or milk the suprapatellar pouch
Needle aspiration and injection techniques
Palpating anatomic landmarks significant to the procedure
Realistic tactile feedback throughout procedure

Features

Ultrasound compatible
Highly durable replaceable tissue for multiple uses
Realistic tactile feedback includes:
- Sensation of bony contact if needle hits the patella
- Sensation of bony contact if needle hits the femur
- Inability to aspirate the syringe while the needle tip is in the soft tissue superficial to the join capsule
- Easy aspiration of joint fluid into the syringe once entry has been achieved
Fluid can be left clear or be colored if desired
Ability to increase or decrease size of effusion with up to 60 cc of fluid
