Composite Obstetrical Forceps Jason H Collins M.D.  Pregnancy Institute

The Evolution of Forceps Obstetrical forceps were originally made from wood Use on liveborns may have begun with the Chamberlains in the1600’s Innovation in forceps design have ended with current steel configurations. The measurement of forces required for delivery is now necessary in the 21st Century.

The Forceps Dilemma Not knowing the quantity of      force used for delivery is no longer acceptable. Whether one uses forceps or vacuum extractor ,the traction force needed has limits beyond which injury occurs to mother and infant. 21st Century Obstetrics will require an instrument that accurately measures traction force .Once documented, a training simulator will be next based on that data & cases.

Forceps Design Using a composite material which equals steel. Formulate a sensor which can be embedded. Transfer force to a pattern which can be recorded. Design a display which  is dynamic/real-time. Accumulate case histories to serve as examples. Transfer examples to a computerized “force arm”. Create 3-D animation for a simulator/trainer.

Forceps Design A NASA Technology problem statement was submitted requesting a specialized sensor for composite material.

Composite /Sensor Selection and Testing A Composite was selected from commercial sources and will be reinforced with fiber. Fiber Optic sensor technology from FBS will serve as the embedded mechanism.Tolerances to heat and molding are being tested. A prototype steel forceps with fiber optic sensing has been tested and  is successful. A prototype composite has been molded and will be tested for design conformity and integrity. Clinical testing of the final sensored composite prototype will take place . Commercialization will follow worldwide.

Composite Forceps and  21st Century Obstetrics Pregnancy Institute is dedicated to improving pregnancy outcome through innovation . NASA Technology Transfer facilitates problem statements to practical solutions. Through a Space Act Agreement  PI has gone from  problem definition to concept to prototype with the assistance of F&S and Prism Corp. With final commercialization ,the issue of injurious forceps delivery will be delegated to the 20th century . The development of a forceps delivery trainer/simulator will be the ultimate objective of this effort to ensure that any obstetrical provider will be skilled in instrumental delivery before assuming the responsibility of OB care.
