• Two specific examples are detailed: using 0.24 mm stainless steel capillary and 30 G injection needles.
• Scanning Electron Microscopy (SEM) was employed to analyze the manufacturing process and needle characteristics.

Main Results:

• The SEM analysis visually documented each stage of needle fabrication.
• The process confirmed the viability of using stainless steel capillaries and injection needles as precursors.
• The resulting needles are suitable for suturing applications, demonstrating successful adaptation of intermediate technology.

Conclusions:

• The described manufacturing process is a practical approach for producing essential surgical suturing needles.
• This method leverages intermediate technology, making it suitable for developing countries.
• The findings support the increased availability of affordable surgical instruments in resource-constrained environments.
