LucentMed is a direct manufacturer of Duodenal Endoscopic Brushes, offering medical institutions a stable and reliable procurement option.
Our series of disposable endoscopic cleaning brushes features highly elastic and flexible bristles that provide superior cleaning power and are resistant to shedding, effectively removing debris and biofilms from internal lumens. Compliant with medical manufacturing standards, our products are meticulously crafted and safe for use.
As a factory with comprehensive manufacturing capabilities, we are able to supply cleaning brushes in bulk—ideal for departmental stocking and routine use—at a highly cost-effective price point.
Compared to standard cleaning tools, LucentMed's Duodenal Endoscopic Brush effectively removes the protective layers formed by bacterial accumulations on the inner walls of the instrument channels—a critical source of contamination that is notoriously difficult to eliminate using traditional cleaning methods.
Our product is specifically engineered to accommodate the complex architecture of duodenoscopes, with a particular focus on reaching "dead zones"—such as the recesses surrounding the elevator mechanism—that remain inaccessible to conventional cleaning brushes.
Designed for use in conjunction with a borescope, this product enables visual verification of the interior lumen, ensuring that the cleaning process continues until no visible contaminants remain.
In duodenoscope reprocessing, a critical challenge lies in cleaning the elevator mechanism. This task requires the use of a micro-brush or fine-bristled brush—a role for which the Duodenal Endoscopic Brush manufactured by LucentMed is ideally suited.
After removing the distal cap, use the cleaning brush in conjunction with the raising and lowering movements of the elevator to scrub both its sides and internal grooves—paying particular attention to tiny crevices.
Use a 20 mL syringe to draw up cleaning solution, then repeatedly raise and lower the elevator mechanism at least three times.
During the cleaning of the distal tip, scrub the grooves surrounding the forceps channel outlet to prevent the retention of residual debris.
In accordance with relevant medical regulations, there are specific monitoring requirements regarding the quality of endoscope drying. When used in conjunction with a borescope, the Duodenal Endoscopic Brush enables the rapid identification of residual water films on the inner walls of the channels. This prevents microbial proliferation caused by moisture, thereby eliminating—at the source—the risk of secondary contamination following disinfection.
For complex devices such as duodenoscopes and endoscopic ultrasound scopes, our product facilitates real-time visualization of the elevator hinge and internal grooves. This ensures the complete removal of biofilms, thereby mitigating the risk of healthcare-associated infection outbreaks.

Specifications |
Note |
|
Brush Head Diameter |
Φ2.2 mm or Φ2.8 mm |
Selection should be based on the inner diameter of the specific pipe type. |
|
The Φ2.2mm size offers broad compatibility; the Φ2.8mm size is suitable for larger-diameter pipes. |

|
Brush Body Length |
1200 mm or 2200 mm |
1200 mm: Commonly used for cholangioscopes or shorter duodenoscopes. |
|
2200 mm: Commonly used for standard-length duodenoscopes or enteroscopes. |

|
Bristle Material |
Nylon / PBT |
It features excellent wear resistance and flexibility, minimizing the risk of damage to the inner walls of the channel. |
|
Handle Material |
Stainless Steel (Reusable) |
Constructed with a stainless steel spring hose, it is capable of withstanding high-temperature and high-pressure sterilization. |
|
Brush Head Design |
Blunt Tip Design |
It features a rounded, blunt tip to prevent scratching or puncturing the endoscope's working channel during insertion and brushing. |
|
Scope of Application |
Duodenoscope, Cholangioscope |
Suitable for endoscopes with an instrument channel inner diameter greater than 2.2 mm or 2.8 mm. |
The instrument channel of a duodenoscope is typically narrower than that of a gastroscope, yet wider than that of an ultra-thin bronchoscope. For standard duodenoscopes (such as those used in ERCP procedures), the inner diameter of the instrument channel typically ranges from 3.2 mm to 3.7 mm.
Therefore, a Φ2.8 mm Duodenal Endoscopic Brush provides superior cleaning friction, whereas a Φ2.2 mm brush navigates more easily through narrow or tortuous channels.
Duodenoscopes are relatively long instruments, with an effective length typically exceeding 1300 mm. Consequently, it is recommended to select a cleaning brush with a length of 2200 mm or greater to ensure it can fully traverse the entire length of the instrument channel.
For shorter pediatric scopes or specialized endoscopes, the 1200 mm size may be considered; please contact LucentMed directly for personalized consultation and guidance on the optimal solution.
This product belongs to LucentMed's series of disposable endoscopic cleaning brushes. Featuring a plastic (POM) handle, it is designed for single-use disposal immediately after use, thereby eliminating the risk of cross- infection.
Upon request, a reusable version can be custom-manufactured; this variant features a stainless steel handle and requires thorough cleaning and high-level disinfection after each use.
A: They are primarily used for brushing complex, narrow lumens within a duodenoscope—specifically the elevator mechanism channel, instrument channel, and auxiliary water channel—to remove bile, mucus, biofilm, and residual debris, thereby meeting the infection control requirements for endoscope reprocessing.
A: Duodenoscope lumens are narrower, feature more curves, and possess a more complex structure. Standard colonoscope brushes typically have a larger diameter and are too rigid; using them can easily cause the brush to get stuck within the scope or damage the elevator mechanism.
Dedicated brushes are more flexible, have a smaller diameter, and offer superior compatibility.
A: We offer two types: a single-use version and a version suitable for high-temperature and high-pressure (autoclave) sterilization. You may select the option that best aligns with your department's infection control protocols and budget.
A: It is ideal for endoscopy centers that perform batch cleaning, centralized disinfection, and rotational use of instruments. This packaging facilitates easier inventory management and stocking, reduces the frequency of supply requisition requests, and enhances overall operational efficiency.
A: The brush head features a rounded, blunt protective design; the bristles are soft and densely packed, while the brush shaft is flexible and smooth. When used in accordance with standard operating procedures, the brush will not scratch the inner walls of the endoscope or damage the elevator mechanism components.
A: The primary factor to check is the inner diameter of the instrument channel. For common channel sizes (typically 2.0–3.2 mm), simply select the corresponding small-diameter brush head. We also recommend a brush length of ≥2400 mm to ensure that the entire length of the channel is thoroughly brushed.
A: Yes, it is. The cleaning brush performs only the physical removal of contaminants. After brushing, you must still proceed with the standard protocols for enzymatic cleaning, rinsing, and either high-level disinfection or sterilization, as required.
A: As a professional manufacturer, LucentMed employs a high-density bristle-implantation process, making bristle shedding unlikely under normal usage conditions.
If you do notice any abnormalities, please stop using the brush immediately and contact our after-sales support team for a replacement to prevent any foreign objects from remaining lodged within the endoscope's lumens.
