23 Jul Biological soft tissue cutting test device
Abstract
The invention belongs to the field of biomedical engineering and discloses a biological soft tissue cutting test device. The device comprises a base, a computer, a sliding rod, a vertical guide rail, a vertical stepping motor, a bracket, a force sensor, a cutting tool clamping device, a cutting tool, a soft tissue clamping device, a transverse guide rail and a transverse stepping motor. The biological soft tissue cutting test device is characterized by also comprising a linear guide rail controller and a linear motor. The force sensor, the computer and a data acquisition card form a force measurement system, and the data acquisition card acquires a force signal and stores the force signal in the computer through a PCI (Peripheral Component Interconnect) interface. The cutting force can be measured by the force sensor in real time, so that a quantitative research on the soft tissue cutting is realized. The high-speed cutting of soft tissues can be realized, the automatic measurement in the whole cutting process is realized under computer control, the testing speed is high, the precision is high, and a typical soft tissue cutting database can be rapidly established through a cutting test.
