Contact stage: the needle contacts the simulation object and the force value begins to rise; puncture stage: the needle penetrates the simulation object, the puncture force value reaches a peak and then drops rapidly; stable stage: the needle completely enters the simulation object, and the needle holding force value tends to be stable. The system automatically records the puncture force peak value, average force value, puncture depth, puncture time and other parameters, and generates force- The displacement curve is formed to complete the detection task, clean the simulant debris on the fixture and the platform, and disinfect the contact part of the puncture device. By setting the structure of the protection unit 200, the safety of the staff can be effectively protected during the puncture force detection process of the detection tooling, thereby preventing the staff from accidentally touching the detection structure and causing themselves to be injured. After being injured, the protection unit 200 structure can be quickly activated to safely operate the puncture device.
