23 Jul Dynamic compression device for tissue engineering
Abstract
The utility model discloses a dynamic compression device for tissue engineering, which comprises a loading platform and a compression mechanism. The loading platform is used for placing culture, and the compression mechanism is used for compressing the culture. The compression mechanism includes a fixing support, a first spindle, a second spindle, an eccentric shaft, an eccentric wheel and an ejector rod, the fixing support is mounted on a support, the first spindle and the second spindle are arranged on the fixing support at intervals and positioned on the same axis, the eccentric shaft is mounted between the first spindle and the second spindle, the eccentric wheel fixed onto the eccentric shaft is adjustable in angle, the ejector rod is arranged between the eccentric wheel and the culture, the eccentric shaft is eccentric to the first spindle and the second spindle, the upper portion of the ejector rod penetrates through a through hole formed on the support, a pressing head is fixedly arranged at the lower end of the ejector rod, an elastic piece for supporting the ejector rod and resetting the ejector rod is arranged between the pressing head and the support, and the ejector rod reciprocates in vertical movement under the action of the eccentric wheel to compress the culture dynamically. The dynamic compression device can change lift range by changing the positions of the eccentric wheel due to the fact that the spindles and the eccentric wheel are all eccentric relative to the eccentric shaft.
