Soft Tissue Injection Models

It is becoming essential that all learned procedural and technical, training should include those which are invasive, and be carried out on simulators.

L&T have developed systems using technology, with well researched designs and development to provide models and simulators which present an opportunity for staged learning. Injection is a common form of treatment; the technique and procedure is achieved with great proficiency using the L&T system.

Knee for Aspiration and Injection (70013)

This Knee Trainer presents the complex structure of the knee and is designed for practice of injection and aspiration in realistic conditions. The anatomy of the knee is complete and includes:

the femur and tibia,
collateral ligaments,
cruciates,
patella ligaments
fat pad
menisci
synovial sac charged with aspirant (70012).

These are contained within a joint capsule (70040). The appearance is extremely life-like with the surface of the skin allowing for repeated needle insertion. The muscle and skin are different layers to give a realistic feel and respond easily to the needle.

All materials are non-biological and each part is replaceable. The model can be taken apart to demonstrate the anatomy for educational purposes and to give easy access for the maintenance of the internal structure. It is designed for repeated use as a trainer. The outer skin (70050) and the synovial sac (70030) need replacing from time to time. The model is supplied with two AA1.5 batteries. Fully illustrated instructions are provided. All our products are non-biological, clean and easy to use.

Shoulder Trainer (30010)

The Shoulder Trainer is designed for soft tissue joint injection. The model simulates normal anatomy and is achieved without the use of biological material.

The trainer is suitable for doctors or clinicians and is intended for shoulder injection of the subacromial space, the acromioclavicular joint, the tendon sheath of the long head of the biceps and the glenoid fossa from the anterior and posterior aspect.

When the needle is correctly positioned into the joint, a green light is activated. There are five different sites marked in this way with four lights. The Shoulder Trainer is one of a series of models for practising injection techniques.

L&T have developed a realistic, supple and durable simulated skin made from latex rubber which can be punctured many times. The skin is replaceable. All our products are non-biological, can be stored at room temperature and are very easy to handle. The model is supplied with two AA1.5v batteries.

Fully illustrated instructions are provided for its use and maintenance of the rubber skin and the method by which the skin can be replaced or changed.

Wrist Trainer (30031)

This is designed for the practice of carpal tunnel and 'trigger finger' injections, injections into the first carpo-metacarpal joint and for De Quervain's teno-synovitis.

The trainer simulates the normal anatomical reference points for carpal tunnel, the palmaris longus tendon, the distal wrist crease and the tendon to the flexor carpi radialis. A light is activated when the correct point is reached with the needle and another light shows if the needle touches the medial nerve.

The De Quervain sheath containing the extensor pollicis brevis and the abductor pollicis longus if fused as it passes the radial styloid. A light is activated when the injection is made into the sheath. The correct site for the first metacarpal joint injection is identified by a second light. There is realistic movement and feel to the wrist.

The model is supplied with two AA1.5v batteries.

The Elbow for Joint Injection (30080)

The Elbow model for Joint Injection incorporates a simulated tennis elbow - lateral epicondylitis and golfer's elbow - medial epicondylitis.

A right elbow inflexion allows the practice of injecting either the lateral extensor insertion or the medial extensor insertion as if the patient were either sitting or lying whichever is the operator's preference. When the needle enters the tennis elbow or the golfer's elbow a green light will illuminate; the needle may then be moved in a fan or cone shaped area subcutaneously in order to simulate an actual infiltration of the tendinitis lesion.

The yellow light is activated when pressure is placed on both the lateral epicondar and the medial epicondar to simulate pressure pain.

A red light will illuminate if the needle enters the ulnar nerve which lies behind the medial epicondar. The model is supplied with two AA1.5 volt batteries.
