【Abstract】Inorder toachieve the success rate of the first design of the two-end fixed TPAandaccurately predict itsinsertionandwithdrawal force，thispaperfirstcarredoutacomprehensiveandin-depth theoreticalresearchonthe two-endfixedTPAandrigorouslyderivedtheformula.Thenthecorectioncoeffcientisfittdbyscientific methodto completethe finaldeterminationof thecalculation formulaof insertionandwithdrawalforce.Finall，thetheoretical formulasareverifiedbyexperiments.Theverificationresultsshow thatthecalculatedresultsof insertingandpulling force are more than 85% consistent with the experimental results.The research results have important guiding significance for thedesignof typical TPA，andcaneffectively helpthe scientific developmentand eficient promotionofTPAdesign.
