LucentMed is a reliable manufacturer of disposable live sampling forceps. We offer small-batch samples for evaluation and support customization and volume production once the solution is confirmed. Our products are manufactured using medical-grade materials in compliance with ISO 13485 and ISO 9001 standards, and they hold CE certification and multiple patents.
Each pair of sampling forceps undergoes EO sterilization, and we provide tailored solutions suited to various endoscope types and clinical departments.
Biopsy forceps come into direct contact with a patient's blood and mucosal tissue. Even after cleaning and high-temperature sterilization, reusable forceps may still harbor residual biofilm in concealed areas, such as the jaw hinge or the interior of the spring tube.
By using a disposable type, it can reduce the risk associated with inadequate reprocessing of reusable devices.
Single-use products are brand new for every procedure; the sharpness of the jaws and the opening/closing force remain optimal, avoiding the performance degradation caused by metal fatigue associated with repeated use.
LucentMed maintains strict quality management to ensure high product consistency; every unit undergoes factory testing to guarantee safe use.
Many healthcare systems and professional practices increasingly adopt disposable biopsy forceps due to infection control requirements and workflow considerations.
As a manufacturer deeply committed to the industry, we strictly adhere to these standards and supply compliant products to international buyers and projects.
Disposable live sampling forceps typically consist of the following four parts:
|
Components |
Functional Description |
|
Jaw |
Located at the distal end and made of 304 medical-grade stainless steel, it is responsible for grasping tissue. Common jaw types include: flat cup, spiked, alligator-tooth, rat-tooth, and serrated. |
|
Sheath/Catheter |
A long, flexible tube connecting the jaw head to the handle; it utilizes a spring-coil or plastic-coated spring-coil structure to ensure smooth advancement through curved endoscope channels. |
|
Pull wire |
A pull-wire housed within the flexible tube; it transmits force from the handle to control the opening and closing of the jaw head. |
|
Handle |
Located at the proximal end for the physician to hold and operate; it features a sliding grip or finger rings to control the opening and closing of the jaws. |
1. Plain Cup: Features smooth, cup-shaped jaws; suitable for routine mucosal tissue sampling with minimal tissue trauma.
2. Serrated Cup: Features serrated edges on the cups for superior gripping power; prevents tissue slippage and is suitable for slippery or tough tissues.
3. With Needle: Features a central positioning needle that anchors the forceps upon insertion, ensuring precise sampling; particularly suitable for use in the highly motile gastrointestinal tract.
4. Alligator/Crocodile Jaw: Features jaws resembling alligator teeth with strong biting force; suitable for grasping larger or harder tissue samples and for foreign body retrieval.
5. Rat Tooth: Features sharp, tooth-like jaws that provide an exceptionally secure grip; suitable for fibrotic or scarred tissue.
The core principles for selecting disposable biopsy forceps are: use "smooth-cup" jaws for soft tissue, "serrated" jaws for slippery tissue, "needle" jaws for difficult-to-access locations, and "alligator" jaws for hard tissue.
Selection should be flexibly tailored to the specific anatomical site and clinical objective; you can consult LucentMed with your specific requirements.
|
Site/Endoscopy |
Recommended Jaw Types |
Rationale |
|
Esophagus |
Flat-cup / With needle |
Mucosa is thin; flat-cup type causes minimal trauma; needle-equipped type allows for precise positioning during esophageal peristalsis |
|
Flat-cup / With needle |
Gastric wall exhibits active peristalsis; needle-equipped type provides secure anchoring; flat-cup type suffices for routine examinations |
|
|
Duodenum |
With needle |
Intestinal lumen features sharp angles and strong peristalsis; needle-equipped type offers distinct positioning advantages |
|
Serrated / Flat-cup |
Colonic mucosa is slippery; serrated type prevents slippage; studies indicate superior sample quality with flat-cup or oval types during colonoscopy |
|
|
Flat-cup (Small diameter 1.8mm) |
Airway mucosa is extremely fragile; requires small-diameter, flat-cup type to minimize injury |
|
|
Bladder/Urethra |
Serrated / Alligator-tooth |
Mucosa is slippery and tumor tissue is tough; requires strong grasping force |
|
Clinical Purpose |
Recommended Gripper Heads |
Features |
|
Routine screening/physical examination |
Flat Cup Type |
Simple operation, minimal trauma, and meets standard pathological requirements |
|
Helicobacter pylori testing |
Flat Cup Type (Small Jaw) |
Requires small sample volumes; small jaw size minimizes bleeding |
|
Early cancer screening/staging |
Alligator Tooth Type / Large-Aperture Flat Cup Type |
Suitable for obtaining larger, deeper samples to assess depth of invasion |
|
Inflammatory Bowel Disease (IBD) |
Flat Cup Type / Serrated Type |
Ideal for multi-site/multi-sample collection; flat-cup design offers high efficiency |
|
Tumor characterization |
Alligator Tooth Type / Needle-Equipped Type |
Strong biting force for hard tissue; precise anchoring capability for difficult-to-reach locations |
|
Foreign body retrieval |
Alligator Tooth Type |
High biting force; suitable for grasping various foreign bodies |
|
Parameter |

|
Working length |

|
Sterilization method |
Ethylene oxide (EO) sterilization; individually sterile-packaged |
|
Material |

4. Compliance & Certification: Manufactured under the ISO 13485 medical device quality management system; complete factory inspection reports and sterilization certificates are available.
A: This is usually due to an inappropriate choice of forceps tip or incorrect handling technique.
For slippery mucosal surfaces (such as colon polyps), it is recommended to use serrated or needle-equipped biopsy forceps to enhance grip and effectively prevent slippage.
A: When retrieving the sample, the jaws must be closed to fully retract the positioning needle into the forceps cup before withdrawing the device from the endoscope.
Forcing a withdrawal while the needle tip is exposed can easily tear the retrieved tissue sample, damaging the pathological specimen.
A: The working length of the biopsy forceps must exceed the actual working length of the endoscope.
If the forceps are too short and the jaws are activated before the tip fully extends beyond the distal end of the endoscope, the jaws may scratch the endoscope's precision optical lens, causing irreversible damage.
