Langenbeck-Ryder curved surgical needle holder with suture groove, 18 cm - Helmut Zepf (41.369.18) - Delynov

What is the Helmut Zepf Langenbeck-Ryder needle holder?

The Langenbeck-Ryder needle holder, referenced under code 41.369.18 by the manufacturer Helmut Zepf Medizintechnik GmbH, is a manual surgical instrument designed for handling sutures. This model is distinguished by a curved configuration and a total length of 18cm, offering leverage and visibility adapted to oral surgery procedures. Its structure includes a specific groove for the thread, allowing it to be stabilized during traction and transmucosal passage phases. This instrument is a classic component of precision instrumentation for practitioners requiring a firm hold of the needle without risk of accidental slippage during the operative gesture.

What are the clinical indications for this langenbeck needle holder?

This langenbeck needle holder is primarily indicated for suture procedures in oral, periodontal, and implant surgery. Its curved shape makes it particularly useful for suturing soft tissues in areas with reduced visibility or restricted access, such as tuberosity or retro-molar regions. It is used by dental surgeons to hold needles of different curvatures when performing simple points, U-stitches, or continuous sutures. The presence of the thread groove helps prevent tangling or shearing of the suture material, which is crucial when handling fine threads in micro-surgery or periodontal plastic surgery.

What are the technical characteristics of instrument 41.369.18?

The Helmut Zepf 41.369.18 needle holder features precise technical characteristics: a length of 18cm and a curved working end. The major distinctive element is the integration of a thread groove at the jaws, designed to secure the positioning of the suture strand. This technical specificity reduces mechanical stress on the thread while ensuring a robust grip on the needle. The instrument is designed by Helmut Zepf Medizintechnik GmbH, guaranteeing manufacturing that meets high-quality surgical instrumentation standards. Its 18cm dimension offers a balance between hand maneuverability and clinical reach to achieve deep operative sites.

What are the contraindications for the use of this device?

Contraindications for the use of this surgical needle holder are mainly related to inappropriate use of the instrument. It must not be used to handle needles of calibres disproportionate to the size of its jaws, at the risk of damaging the closing mechanism or deforming the thread groove. Furthermore, as with any metallic instrument, its use is contraindicated in patients with a known hypersensitivity to the metals composing the alloy, although this is rare for transient contact instruments. It is imperative not to use the instrument if it shows signs of corrosion, deformation, or locking dysfunction to guarantee patient safety.

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

As a reusable steel surgical instrument, this Helmut Zepf needle holder requires a rigorous sterilization and decontamination protocol after each intervention. Although the instrument itself is not a resorbable device, it is used to place sutures that may be. Precautions include manual or ultrasonic cleaning followed by autoclave sterilization according to the parameters recommended by the manufacturer Helmut Zepf Medizintechnik GmbH. The condition of the thread groove and the fit of the jaws should be checked regularly to ensure that no biological residue remains. Proper maintenance prevents oxidation and maintains the precision of the clamping mechanism necessary for suture safety.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized company in the dental and surgical instrumentation sector. Although specific data on the regulatory class or CE marking are not detailed in the current technical sheet, this product is manufactured according to the German industrial quality standards associated with the Helmut Zepf brand. Practitioners are invited to refer to the instructions for use and the manufacturer's catalog for precise details on compliance certifications and ISO standards applicable to this 18cm surgical instrument. Traceability is ensured by the technical reference 41.369.18 affixed to the device.
