Mathieu-Kocher Needle Holder Number 5074 Tungsten Carbide 14cm - Hu-Friedy - Delynov

What is the Hu-Friedy Mathieu-Kocher #5074 needle holder?

The Mathieu-Kocher #5074 needle holder from the Hu-Friedy brand is a manual surgical instrument specifically designed for the manipulation of suture needles. This model is distinguished by its robust 14cm structure and the integration of reinforced jaws. As a mathieu tungsten needle holder, it utilizes tungsten carbide inserts on its gripping surfaces. This material, recognized for its extreme hardness, offers increased wear resistance and allows the needle to be held firmly without risk of slipping or axial rotation during trans-mucosal passage. Manufactured by Hu-Friedy Mfg. Co., LLC, this instrument meets Class I requirements for medical devices, guaranteeing a quality standard adapted to clinical environments of oral and implant surgery.

What are the clinical indications for this instrument?

This instrument is indicated for suturing soft tissues during various oral surgery interventions. It is particularly used by implantologists and periodontists for flap closure after implant placement, bone grafting, or periodontal plastic surgery. The Mathieu-Kocher design is ideal for practitioners seeking a spring mechanism allowing for rapid handling. This mathieu tungsten carbide needle holder ensures optimal needle stability, which is crucial for achieving precise sutures, whether simple points, mattress sutures, or continuous sutures. Its use is strictly reserved for qualified healthcare professionals, in accordance with the guidelines of the manufacturer Hu-Friedy located in Chicago.

What are the technical characteristics of this needle holder?

The Mathieu-Kocher #5074 needle holder features a total length of 14cm, a standard dimension that offers an optimal balance between leverage and maneuverability in the mouth. The major technical feature lies in its jaws equipped with tungsten carbide inserts. This hard metal is brazed onto the instrument's jaws to create a textured and durable contact surface. Unlike standard steel, tungsten limits the dulling of the gripping serrations, thereby extending the technical life of the instrument. The ratchet locking mechanism located at the handle allows for secure closure by palm pressure, freeing the practitioner from the need to insert fingers into rings, which can increase execution speed during complex suturing phases.

What are the contraindications for the use of this device?

According to information provided by the manufacturer Hu-Friedy Mfg. Co., LLC, specific contraindications are not exhaustively listed beyond standard surgical protocols. However, the use of this needle holder is contraindicated for any person who does not have the qualification of a healthcare professional. It is imperative not to use the instrument for tasks for which it is not intended, such as handling thick wires or other rigid materials that could damage the tungsten carbide inserts. Compliance with the indications and contraindications mentioned in the instructions is mandatory. Any use diverted from its primary function as a needle holder for soft tissue suturing can lead to device failure.

What are the maintenance precautions for a non-resorbable instrument?

Although the term resorption applies to sutures, the maintenance of this non-resorbable metal instrument requires rigorous precautions to preserve its properties. As a Class I device, the Hu-Friedy needle holder must be cleaned, disinfected, and sterilized before each use. It is essential to follow the manufacturer's cleaning instructions to avoid corrosion, particularly at the joint and the tungsten carbide inserts. Special attention must be paid to complete drying before autoclaving. Although tungsten is extremely resistant, inadequate maintenance or the use of non-recommended corrosive chemicals can alter the bond between the insert and the steel body of the instrument. Regular inspection of the spring mechanism and the ratchet is advised.
