Product Description

Application:Bone screws are used for internal fixation of fractures during orthopedic surgery, and are quite helpful in fracture treatment and reconstructive surgery. Applicable to different thread types (deep thread, full thread, half thread), different nominal diameters (HA/HB1.5-8.0mm), and different uses (cortical bone screw, cancellous bone screw, cannulated screw).Bone joint implant metal bone screw screws in and out torque tester is a multi-functional composite test equipment tailored according to the performance requirements of metal bone screws, which can be used for screw rotation torque test, self-tapping force test, Axial pullout force test, torsional performance test and other related performance tests of bone screws.Design with reference to national standards and relevant international standards, comply withvarious standards, and achieve high concentration of functions.The screwing in torque is used to prevent the screw from breaking during screwing in, and ensure that produce important parameters for easily screwing in screws. The screw in torque should be far less than the torsional yield strength of the bone screw and the matchingscrewdriver. The screwing out torque is an important parameter used to avoid the fracture of the screw during screwing out and ensure that the doctor can easily screw out the screw. The screwing out torque should be far less than the torsional yield strength of the bone screw and the supporting screw.

Features:
1: High-precision symmetrical torque sensor, wide linearity, good stability, to ensure the test accuracy of torque load.
2: Wide range of torsional test speeds, 1r/min-30r/min3: Various control methods such as automatic torque load control, automatic hold, cycle control and self-programming control. Maximum torque and maximum fracture torsion angle test, screw-in torque test, bone screw fracture position test, bone screw torsional yield strength test.4: Torque and torsion angle are automatically tracked and measured, and the test curve, torque value, torsion angle, and torsion speed are displayed in real time.5: Simultaneous display of multiple curves (torque-time curve, torque-torsion angle curve, angle-time curve, etc.), self-setting of coordinates, self-adjustment of full scale.
