Abstract

The invention relates to a torque test device. A stimulator to be tested is fixedly arranged on a fixation base; a stimulation wire to be tested on the stimulator to be tested passes through a fixation member and is fixed by the fixation member; torque is applied to the other end of a rotation shaft, and the torque is transferred to the stimulation wire to be tested through the rotation shaft, a connection frame and the fixation member; and by visually observing whether the joint between the stimulator to be tested and the stimulation wire to be tested is deformed or broken, whether the jointbetween the stimulator to be tested and the stimulation wire to be tested can withstand the torque can be judged. The invention also provides a torque and tension test device. The torque and tension test device realizes torque and tension test of the joint between the stimulator and the stimulation wire through a structure similar to that of the torque test device and the tension of a heavy object.

Description

technical field [0001] The application belongs to the technical field of detection equipment, and in particular relates to a torque and a torque and tension detection device. Background technique [0002] Nowadays, with the continuous development of medical technology, however, clinically, there are still many neurological diseases that lack an effective cure. Patients need to take medicine for many years or even life, and a certain proportion of patients have serious side effects after taking medicine. Therefore, implantable medical devices have become an alternative therapy, safe and reversible, and are being used more and more clinically. An implantable neurostimulator is a type of active implantable medical device that regulates the conduction of the nervous system through electrical stimulation, thereby restoring or improving human body functions. [0003] Implantable neurostimulators generally include a pulse generator and electrode wires, and the pulse generator and ...
