Modification of a syringe for aspiration biopsy
1Department of Radiology, St Francis Medical Center, Monroe, La.
Abstract:
To reduce the risk of accidental needle-stick injury during fine-needle aspiration biopsy, a syringe to be used in such procedures was modified. In five cases, a small hole, punctured in the barrel of a syringe above the level to which the plunger is routinely retracted, allowed the syringe to fill with air. The specimen was expressed onto a slide without the necessity of removing and reattaching the needle. This modification reduces the need to handle contaminated needles.
Insights
This study modified a syringe to prevent needle-stick injuries during fine-needle aspiration biopsy. The new design allows air to enter the syringe, simplifying specimen expulsion and reducing handler contamination risk.
Area of Science:
- Medical Devices
- Surgical Safety
- Biopsy Techniques
Background:
- Accidental needle-stick injuries pose a significant risk during fine-needle aspiration (FNA) biopsy procedures.
- Handling contaminated needles increases the potential for pathogen transmission and sharps-related injuries.
Purpose of the Study:
- To develop and evaluate a modified syringe designed to minimize the risk of needle-stick injury in FNA biopsies.
- To improve procedural safety by reducing the need for direct handling of contaminated needles.
Main Methods:
- A novel modification was introduced to the syringe barrel, incorporating a small air-vent hole.
- This modification allows for air to enter the syringe barrel during plunger retraction.
- The modified syringe was tested in five clinical cases.
Main Results:
- The air hole enabled the syringe to fill with air, facilitating specimen expression onto a slide.
- The modification eliminated the need to detach and reattach the needle for specimen expulsion.
- This procedural change significantly reduced the handling of contaminated needles.
Conclusions:
- The modified syringe design offers a safer alternative for FNA biopsy procedures.
- This innovation effectively mitigates the risk of needle-stick injuries and reduces handler exposure to contaminated sharps.
