Area of Science:

  • Gastroenterology
  • Medical Devices
  • Surgical Technology

Background:

  • Current endoscopic biopsy forceps can be limited in sample size and may cause tissue trauma.
  • There is a need for improved biopsy tools that enhance diagnostic yield and patient comfort.

Purpose of the Study:

  • To describe a novel system of flexible endoscopic biopsy forceps.
  • To highlight the design, function, and advantages of these disposable forceps.

Main Methods:

  • A new biopsy forceps design featuring a central wire with a barbed spike and sprung steel jaws.
  • An outer plastic sleeve activates the jaws, allowing for tissue capture and retrieval.
  • The device facilitates sequential biopsy collection within a single endoscopic pass.

Main Results:

  • The described forceps produce larger and less traumatized biopsies compared to existing single biopsy forceps.
  • The unique barb mechanism securely grips tissue, enabling cleaner and bigger biopsies.
  • Up to six biopsies can be collected sequentially in an ordered manner.

Conclusions:

  • This disposable endoscopic biopsy forceps system is simple and inexpensive to produce.
  • The forceps offer improved performance in terms of biopsy size and tissue integrity.
  • The design has the potential to enhance diagnostic accuracy in endoscopic procedures.
