The invention provides a device for measuring intracranial puncture errors of a mechanical arm under magnetic navigation. The device comprises a bottom plate, the bottom plate is provided with a rectangular plane coordinate system, and a first base is detachably arranged on the bottom plate; a first cylindrical through hole is formed between the upper surface and the lower surface of the first base, and the diameter of the first cylindrical through hole is the same as the diameter of a spherical foam ball which is used for testing; when the first base is connected with the bottom plate, the center point of the first cylindrical through hole coincides with the original point of the plane rectangular coordinate system; a second base is detachably arranged on the first base in the Z-axis direction, and a second cylindrical through hole is formed between the upper surface and the lower surface of the second base; the diameter of the second cylindrical through hole is the same as the diameter of a puncture needle used for testing; when the second base is connected with the first base, the puncture needle penetrates through the second cylindrical through hole. The device is low in cost and easy to use, the measurement process of the puncture errors can be simplified, and the measurement precision is higher.
Description
technical field [0001] The invention relates to the field of measuring error devices, in particular to a device and method for measuring errors in intracranial puncture of a manipulator under magnetic navigation. Background technique [0002] Minimally invasive and precision medicine are gradually becoming the common goal pursued by the surgical community. Computer-assisted surgery (CAS), also known as computer navigation technology, is a manifestation of minimally invasive precision medicine. Electromagnetic navigation is an emerging navigation technology. It has been widely used in neurosurgery, cardiovascular intervention, bronchoscopy, joint surgery, spine surgery and other fields. As the direct implementer of navigation surgery, the robotic arm has high requirements for puncture accuracy. Therefore, the measurement of the puncture accuracy of the manipulator is of great significance. [0003] In the prior art, in the accuracy test of intracranial puncture with a mecha...
