The Nakao Ejector™ Biopsy Forceps was invented after a nurse at our endoscopy unit was injured by a needle stick while trying to extricate a specimen from a biopsy forceps. The patient was both HIV and hepatitis B antigen positive. Later that month, an article entitled The Needle Stick was published in the SGNA Journal, describing the horrifying experience of Lindsay Sattler, past president of the Society for Gastroenterology Nurses: "It was an ordinary day in an ordinary endoscopy unit with a veteran nurse doing an ordinary procedure. The patient who underwent an upper endoscopy with biopsy was HIV positive with full blown AIDS. I used a 25 gauge needle to remove the biopsy specimen from the forceps and place the pieces in formalin. The tissue was sticking to the forceps. I suddenly stuck my right index finger with that 25-gauge needle… How could I have done something so stupid? This was really a bad dream. This could not be happening to someone who had been an endoscopy nurse for nearly 18 years.” Ms. Sattler was treated with AZT, developed gastrointestinal side effects, and lived in fear of AIDS for one full year. She concludes her article: “I hope that this account will save someone the agony of this experience. It just might save a life.”
Ms. Sattler had not done something stupid. Nor had the nurse who was injured in our endoscopy unit. The fault resides entirely with the design of the biopsy forceps, which necessitates the use of a sharp to free a specimen. Indeed, the forceps cup includes a hole specifically intended for just this purpose. OSHA regulations regarding the use of sharps are clear, calling for new designs of medical instruments in order avoid injury. Nevertheless, every time a biopsy is performed, an accident is waiting to occur.
The Nakao Ejector™ Forceps was invented in order to prevent injury from needle sticks. This new forceps is designed to release the specimen automatically without the assistant ever having to touch the forceps’ distal end. This is accomplished with a small prong co-joined to the cup hinge. When the cups are opened, the prongs extend into the holes dislodging the tissue. One shake of the forceps in preservative is required to free the specimen.
