Dingmann Mouth Gag, 150 mm

## Overview

The Dingmann Mouth Gag is a self-retaining mouth gag that holds the mouth open and maintains access to the oral cavity and oropharynx throughout the procedure without continuous manual support. Within the Aesculap catalog it is classified under Self-Retaining Retractors in the Mouth Gags group. The DINGMANN designation identifies the established pattern of this instrument, allowing procurement teams to specify a consistent, repeatable configuration across orders.

Self-retaining instruments of this kind are valued in the operating room because they hold their position once set, maintaining exposure of the surgical site and reducing the need for a dedicated assistant to provide continuous retraction. This supports a stable, reproducible working field during oral surgery, ENT procedures.

## Design Characteristics

The listed working length is 150 mm. The catalog lists the following dimensional data for this reference: 12 mm, ⅜“ / 25 mm, 1“ / 85 mm, 3 ¼“ / 150 mm, 6“ / 70 mm, 2 ¾“ / 145 mm, 5 ¾“. The item is configured as frame only.

The self-retaining mechanism allows the instrument to lock into an open position, so that once the surgeon has established the required exposure the instrument holds that position independently. This characteristic distinguishes self-retaining retractors from hand-held retractors, which require an assistant to maintain force throughout the procedure.

## Applications

Based on its instrument type and catalog classification, the Dingmann Mouth Gag is applicable to oral surgery, ENT procedures, dental and oropharyngeal access. These applications follow directly from the instrument’s design as a mouth gag; uses beyond those supported by the catalog classification are not claimed.

## Identification and Traceability

This product is identified by catalog reference OM105R and registry identifier REG-BV-000136. It is sourced from Aesculap Surgical Instrument Catalog, page 808, under the Mouth Gag section, preserving full traceability from the catalog to the product record.

## Self-Retaining Mechanism and Clinical Rationale

The defining feature of the Dingmann Mouth Gag is its self-retaining action. Once the surgeon establishes the required exposure, the instrument locks into an open position and holds that position on its own for the duration of the step. This has two practical consequences in the operating room. First, it removes the need for a dedicated assistant to apply and sustain retraction force, which can free a pair of hands for other tasks at the table. Second, it delivers a steady, reproducible degree of exposure rather than one that varies with an assistant’s fatigue or position. For mouth gags, where a consistent working field supports careful dissection and visualization, a self-retaining design is a common choice. The instrument is set, checked, and adjusted as the procedure requires, and released when exposure is no longer needed.

## Applications in Detail

The Dingmann Mouth Gag is applicable to the following, each of which follows directly from its classification as a mouth gag:
– Oral surgery: maintaining an open field within the oral cavity.
– Ent procedures: access to structures of the ear, nose, and throat.
– Dental and oropharyngeal access: holding the mouth open to expose the oropharynx.
These application areas describe where an instrument of this type is used; specific clinical outcomes are not claimed, and any use beyond the catalogued classification is a matter for the operating surgeon’s judgment.

## Handling and Reprocessing Considerations

Instruments in this catalog are reusable surgical instruments. Reusable instruments of this class are typically reprocessed between uses in line with the healthcare facility’s validated cleaning, inspection, and sterilization protocols, and are inspected for correct function of any moving or locking parts before use. Where an instrument incorporates a ratchet, rack, or other self-retaining mechanism, that mechanism is checked to confirm it engages and releases correctly. Specific reprocessing parameters, sterilization methods, and material details are confirmed against the manufacturer’s instructions for use and are not asserted here beyond what the catalog records.

## Ordering Information

The Dingmann Mouth Gag is offered on a request-a-quote basis. Pricing is not published; hospitals, surgical centers, distributors, and procurement teams are invited to send an inquiry for current availability and quotation. Quantities and any accompanying reprocessing or handling requirements can be confirmed at the time of inquiry.
