While the procedure of amniocentesis is considered safe, there are still risks to both the fetus and the mother. The goal of the research was to determine the values and profiles of the forces that occur during the penetration of real tissues with a needle intended for use during amniocentesis. The data on force exerted during puncture was measured in relation to insertion into organic material from domestic pigs, a mammal similar in size and mechanical properties of tissues to humans. The results showed a local increase in the force value when piercing the skin and the uterine wall. The findings prove the usability of measurements done on porcine tissues for at least initial planning of the medical training devices.
