Surgical Spreader No. 9 folded towards the handle 70x11mm - Hu-Friedy - Delynov

What is the Hu-Friedy #9 surgical retractor?

The #9 surgical retractor is a manual instrument developed by Hu-Friedy Mfg. Co., LLC, specifically intended for tissue manipulation during operative acts in dental offices or hospital settings. This model is distinguished by a working part measuring 70x11mm, featuring a particular inclination as it is bent toward the handle. This structural design aims to improve grip comfort for the practitioner while ensuring an effective soft tissue maintenance function. As an instrument in the INSTRU category, it meets the needs for direct visibility of the surgical site by pushing aside obstructing anatomical structures. Hu-Friedy brand manufacturing quality guarantees a tool adapted to the requirements of modern oral surgery.

What are the clinical indications for this tissue retractor?

This tissue retractor is primarily indicated in all oral surgery procedures requiring clear exposure of the alveolar bone or underlying structures. In implantology, it is used to hold the gingival flap at a distance during drilling or implant placement. In periodontal surgery or during complex extractions (impacted wisdom teeth), this dental surgical retractor helps secure soft tissues, thus avoiding accidental trauma related to the use of rotary instruments. Its 70x11mm dimension makes it particularly useful for posterior sectors where space is restricted, while providing a sufficient bearing surface for stable and atraumatic tissue retraction throughout the duration of the procedure.

What are the technical characteristics of the #9 retractor?

Technically, this Hu-Friedy instrument features a 70x11mm working end. The major specificity of this #9 model lies in its orientation: the blade is bent toward the handle, an ergonomic feature that modifies the approach angle compared to standard straight retractors. This geometry allows the surgeon or assistant to exert effective traction without masking the field of vision, thus facilitating precision work. The instrument belongs to Class I of medical devices, which frameworks its professional use. The one-piece design ensures direct transmission of the applied force, allowing rigorous control of the tension exerted on the mucous membranes during the retraction phase.

What are the contraindications for the use of this device?

According to information provided by the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this instrument is strictly reserved for qualified healthcare professionals. General contraindications include using the device in clinical situations for which it was not designed, or by personnel not trained in oral surgery techniques. Although the raw MDR text does not list specific physiological contraindications such as skin allergies, it is imperative to systematically refer to the instructions for use attached to the product before any intervention. Compliance with sterilization and asepsis protocols is also a sine qua non condition for its use in a surgical environment to avoid any risk of cross-contamination.

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

As a reusable and non-resorbable surgical instrument, this retractor requires a rigorous maintenance protocol between each patient. Precautions include thorough cleaning followed by sterilization in accordance with Hu-Friedy manufacturer guidelines. It is essential to visually inspect the condition of the 70x11mm working part before each use to ensure the absence of corrosion or deformation that could compromise patient safety or retraction efficiency. During clinical use, the practitioner must take care not to exert excessive pressure on soft tissues to prevent pressure necrosis or tissue tears. Careful reading of the instructions is essential to guarantee the longevity of the instrument and operative safety.

Who is the manufacturer and what standards are met?

The #9 surgical retractor is manufactured by Hu-Friedy Mfg. Co., LLC, headquartered at 3232 N. Rockwell St. Chicago, Il 60618 USA. This medical device is classified as Class I according to current regulations.
