The Cones Self Retaining Retractor from NJ Medical Instruments is a specialized self-retaining surgical instrument featuring a 3 × 4 prong configuration and jointed arms. The instrument is available with either blunt or sharp prongs, with multiple length and corresponding depth options for professional surgical instrument requirements.

The jointed arm design is a defining feature of the Cones Self Retaining Retractor. Both the blunt and sharp prong variations maintain the 3 × 4 prong arrangement and are offered in four sizes. Available overall lengths are 13 cm (5″), 16 cm (6½”), 20 cm (8″), and 24 cm (9½”).

For both prong variations, the 13 cm (5″) and 16 cm (6½”) models have a 15 mm depth. The 20 cm (8″) model has a 20 mm depth, while the 24 cm (9½”) model has a 25 mm depth. This provides a clearly defined selection of instrument lengths and working-end depths in both sharp and blunt configurations.

With its self-retaining configuration, jointed arms, 3 × 4 prong arrangement, and choice of sharp or blunt prongs, the Cones Self Retaining Retractor provides multiple specified configurations for hospitals, surgical facilities, and professional medical instrument buyers.
