23 Jul Biological soft tissue cutting test device
Abstract
The utility model belongs to the field of biomedical engineering and relates to a biological soft tissue cutting test device. The biological soft tissue cutting test device comprises a base, a computer, slide bars, a vertical guide rail, a vertical stepping motor, a force sensor, a cutting tool clamping device, a cutting tool, a soft tissue clamping device, a horizontal guide rail and a horizontal stepping motor and is characterized by further comprising a linear guide rail controller and a linear motor. The force sensor, the computer and a data acquisition card compose a force measuring system, wherein the data acquisition card acquires force signals and stores the force signals into the computer through a PCI (programmable communication interface), and the force sensor can measure cutting force in real time, so that quantitative study on soft tissue cutting can be achieved. The biological soft tissue cutting test device can achieve high-speed cutting of soft tissues and achieve automatic measurement of the whole cutting process under the control of the computer, is high in test speed and test precision and can help rapidly establish a typical soft tissue cutting database through cutting tests.
