Description

The Barraquer Micro-Needle Holder is an essential tool in the realm of microsurgery, particularly valued in fields such as ophthalmology, neurosurgery, plastic surgery, and dental surgery. Its primary function is to provide precise handling and manipulation of small needles, enabling delicate suturing in sensitive or confined anatomical areas.

Design and Variants

This instrument features a slender, elongated spring handle with two hinged arms, available in both straight and curved jaw configurations. The handle design may include round, knurled, or F-LINE ROUND SOLID ergonomic options, allowing for easy rotation and control. The spring mechanism ensures that the jaws automatically open when handle pressure is released, with some models offering a ratchet locking mechanism for secure needle grasp.

Jaw Specifications

The jaws of the Barraquer Micro-Needle Holder are fine and delicate, available in smooth or serrated forms to provide a secure grip on micro needles. Jaw widths vary from 0.5 mm to 1.2 mm, with a typical jaw length of 9 mm. Some models include carbide or diamond-coated inserts to enhance grip and durability, while the 'pivot-curved' closure design in certain models helps prevent suture snagging or tearing.

Material Options

Constructed from high-quality stainless steel, the instrument is also available in titanium for lightweight, non-magnetic, and non-reflective properties. Select models offer black ceramic or diamond-like carbon coatings for a non-reflective, scratch-resistant, and glare-free operation. Tungsten carbide inserts are available in some models for increased durability.

Size and Compatibility

The Barraquer Micro-Needle Holder comes in various lengths, ranging from 10 cm to 18 cm, accommodating different surgical needs. It is compatible with very fine suture materials, typically sizes 5-0 to 11-0, with specific models recommended for certain suture sizes.

Common Applications

This instrument is commonly used in ophthalmic surgeries involving the cornea, lens, and other delicate eye structures, as well as in periodontal and dental surgeries requiring precise needle manipulation. It is also suitable for small animal surgeries where minimal invasive suturing is needed.

Sterilization and Maintenance

Reusable and autoclavable, the Barraquer Micro-Needle Holder must be sterilized before use. It is compatible with validated manual or automated cleaning procedures, avoiding chlorine solutions. Regular inspection and maintenance are recommended to ensure longevity and optimal performance, with storage in specialized trays to prevent damage.

Handling Guidelines

Intended for use by trained professionals, the instrument should be inspected for cleanliness, damage, and proper operation before each use. Adhering to validated cleaning and sterilization protocols is crucial to ensure patient safety.
