BST -- C Series, 0.5N.m --200N.m Computer Bone Screw Torque Testing Machine(desktop)

1 Important function

1) Torsion test and research with metallic bone screw, absorbable bone screw used in orthopedic implant for torque, torsion angle of breaking and other property.

2) Test and research with orthopedic with different screw threat(deep, shallow, full, half, symmetrical, and asymetrical screw threat), different number of threat and nominal diameter(HA/HB/HC/HD1.5 -- 8.0mm) orthopedic implant.

3) Different usage of orthopedic implant(cortex, loose, hollow bolt), different rotating type of orthopedic implant(slotted point, cross point, inner hexagon, square, inner trangle, quincunx shape), different head of orthopedic implant(cone, ball, semicircle, square shape of head).

4) Torsion test and research with diferent material orthopedic implant(metal, stainless, stainless, absorbable bone bolt, polylactide, L - lactide resin, glycolide, L - lactic acid resin, rigidi polyurethane foam plastic, hydrolytic degradation polymer resin, copolymer).

5) Test and research with surgical implant, non-active surgical implant, synostosis surgical implant.
