GMD Meniscus Resector

The GMD Meniscus Resector is an electrosurgical minimally invasive arthroscopic instrument for radiofrequency meniscus resection. Designed to work inside the human knee, shoulder, and hip joints, it lets surgeons resect, ablate, and coagulate tissue with a single tool — without open surgery.

How it works

The instrument consists of a plastic handle with an inner and outer tube at the working end. The inner tube houses a bipolar loop-electrode; the outer tube shields the loop when the instrument is in its closed position and retracts to expose the electrode during use. Powered by a radiofrequency energy generator, the loop produces a thin layer of radiofrequency plasma capable of:

• Resecting (partially removing) joint tissues
• Ablating (vaporising) tissue
• Coagulating (cauterising) blood vessels

Key advantages

• Minimally invasive. Arthroscopic form factor sized for intra-articular use, dramatically reducing recovery time compared to open joint surgery.
• Three functions in one instrument. Cutting, ablation, and coagulation are all delivered by the same loop-electrode — no tool changes mid-procedure.
• Plasma-based, not mechanical. Radiofrequency plasma cuts cleanly without the mechanical trauma of blade-based resectors.
• Validated indications. Suitable for treating meniscus tears and other intra-articular injuries of the knee, shoulder, and hip.
