Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] combine figure 1 , the present invention is mainly composed of an experimental auxiliary platform 1 and an experimental measurement platform 2. The experimental auxiliary platform 1 is used to realize the transmission of the mechanism, and the experimental measurement platform 2 is used to obtain the force-position data of the soft tissue samples during the experiment in real time.

[0016] combine figure 2 , the experimental auxiliary platform 1 is composed of bracket A1-1, tension wheel 1-2, hexagon socket screw 1-3, scale 1-4, column 1-5, bracket B1-6, tension spring bracket A1-7, steel wire rope 1- 8. It consists of three rollers 1-9, mounting bracket 1-10, preload wheel 1-11, base 1-12, and glass dish 1-13. Extension spring support A1-7 is made up of shaft end retaining ring 1-7-1, support 1-7-2, bearing pin 1-7-3. Th...

Abstract

The invention provides a multifunctional biological in-vitro soft tissue parameter measurement platform. The multifunctional biological in-vitro soft tissue parameter measurement platform mainly comprises an experiment auxiliary platform and an experiment measurement platform. The multifunctional biological in-vitro soft tissue parameter measurement platform can perform four different experiments on a soft tissue, namely, a uniaxial compression experiment (a pressing head slowly presses down to a certain position), a stress relaxation experiment (the pressing head quickly presses down to a certain position and is kept for a period of time), a creep experiment (a steel wire rope suspends weights), and a soft tissue puncture experiment. Micro strain of a soft tissue sample is realized in the mode of driving the steel wire rope to drive by adopting a screw thread pair. According to the multifunctional biological in-vitro soft tissue parameter measurement platform, the problems that a material experiment machine can only be relied in soft tissue measurement and a measurement parameter is single are effectively solved, and the multifunctional biological in-vitro soft tissue parameter measurement platform has a certain popularization value.

Description

technical field [0001] The invention relates to a measuring platform, in particular to a multifunctional biological isolated soft tissue parameter measuring platform. Background technique [0002] Virtual surgery is a very important research content in the field of minimally invasive surgery, and it is difficult to establish an accurate physical model including biological soft tissue parameters. At present, the measurement of soft tissue parameters relies on professional material testing machines, and is limited to the measurement of physical characteristic parameters of some tissues. Compared with the traditional method of using a professional material testing machine to measure parameters, the patent of the present invention provides a simple and effective multi-parameter measurement platform of biological soft tissue, which has a measurement platform and an auxiliary platform. The overall structure of the mechanism is simple, and the transmission is realized by the pulle...
