Abstract

Ειδικό δοχείο τοπικής ψύξεως (8) της αιχμής του διεισδυτή, σε προκαθορισμένη θερμοκρασία, μικρότερη από την θερμοκρασία του προς εξέταση υλικού. Το δοχείο έχει δεξαμενή (9) όπου αποθηκεύεται υγρό ή στερεό ψυκτικό υλικό σε χαμηλότερη θερμοκρασία από το υπό εξέταση υλικό και μία μεταλλική μεμβράνη στην επιφάνεια (10) που μεσολαβεί μεταξύ της ακίδας του διεισδυτή (11) και του ψυκτικού υλικού. Τροποποιημένη ακίδα του διεισδυτή (11) που αποτελείται από ένα κώνο που φέρει ακτινικές προεσοχές (12) πουπροέχουν σε τομείς, συμμετρικά τοποθετημένους, με σκοπό την αύξηση της τριβής στην διεπιφάνεια ακίδας-υλικού. Τροποποιημένη ακίδα (11), που φέρει ακτινικές προεξοχές (13), με σκοπό την μείωση της τριβής στην διεπιφάνεια ακίδας-υλικού. Μέθοδος ερμηνείας της απόκρισης πειραμάτων δείσδυσης σε ιστούς, ώστε να προκύψουν οι μηχανικές ιδιότητες τους και κατά συνέπεια οι φυσιολογικές τους ιδιότητες.
