Retractable Cordless Sickle Scaler CSI1 Handle #6 - Hu-Friedy - Delynov

What is the Hu-Friedy #CSI1 retraction cord packer?

The #CSI1 retraction cord packer is a high-precision manual instrument manufactured by Hu-Friedy Mfg. Co., LLC. This device consists of a thin working end and a #6 serrated handle, designed to optimize clinical handling. As a retraction cord instrument, its structure is specifically adapted to meet the requirements of dental surgeons during gingival preparation phases. Its robust design by Hu-Friedy guarantees durability in accordance with dental prosthetic instrumentation standards. This model belongs to Class I of medical devices, ensuring a level of regulatory compliance suitable for non-invasive interventions in the dental office.

What are the clinical indications for this instrument?

This dental retraction cord instrument is primarily indicated for the management of soft tissues before a final impression or the cementation of fixed prostheses. The clinical objective is to temporarily displace the free gingiva to expose the cervical limits of the preparation. The gingival retraction packer allows the cord to be inserted atraumatically into the gingival sulcus, thus ensuring a clear reading of the margins by the impression material or the intra-oral scanner. Its use is common in restorative dentistry and fixed prosthodontics, where the precision of the subgingival margin is decisive for the long-term success of the treatment.

What are the technical characteristics of the #6 serrated handle?

The #CSI1 retraction cord packer is distinguished by its #6 serrated handle. Unlike thinner standard handles, the enlarged diameter of the Hu-Friedy #6 handle offers a larger contact surface, which can reduce muscle fatigue during prolonged procedures. The deep serrations on the body of the instrument ensure maximum stability, preventing any accidental slipping during the application of controlled pressure. This technical feature is essential for a retraction cord insertion instrument, as it allows the practitioner to guide the active tip with great finesse in restricted access areas, guaranteeing homogeneous packing of the cord.

What are the contraindications for the use of this instrument?

According to the information provided by the manufacturer Hu-Friedy Mfg. Co., LLC, there are no specific medical contraindications listed for this Class I instrument, other than those related to the patient's periodontal status. The use of the serrated gingival retraction packer should be avoided on tissues presenting severe acute inflammation or extreme tissue fragility that would not support mechanical retraction. It is imperative that use be reserved for qualified healthcare professionals. The practitioner must assess gingival health before cord insertion to prevent any irreversible damage to the epithelial attachment.

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

As a reusable metallic instrument and not an absorbable device, the #CSI1 retraction cord packer requires a rigorous sterilization protocol between each patient. Although cleaning details are not specified in the raw text, Hu-Friedy Class I devices must be maintained according to standard asepsis procedures in force in dental surgery. It is recommended to read the instructions carefully before use to respect the sterilization cycles recommended by the manufacturer. Particular attention must be paid to cleaning the serrations of the #6 handle to eliminate any biological residue before autoclaving.

Who is the manufacturer and what standards are met?

The official manufacturer of this device is Hu-Friedy Mfg. Co., LLC, located at 3232 N. Rockwell St. Chicago, Il 60618 USA. This product is classified as a Class I medical device, which corresponds to reusable surgical instruments presenting a low risk. Although specific CE marking is not mentioned in the source data, compliance with Hu-Friedy manufacturing standards ensures consistent quality for dental prosthetic instrumentation. The regulatory text specifies that the use of this instrument is strictly reserved for healthcare professionals and that a careful reading of the instructions is mandatory before any clinical intervention.
