23 Jul Apparatus for implantation of tissue sticking patch
Abstract
The invention provides a device for planting a tissue patch to a lesion position or directly forming a tissue patch at the lesion position. The device of the invention comprises a tube body, tube cavities, injection holes, a head end and a plunger capable of sliding in the tube cavities. The device is characterized in that a plurality of mutually separate tube cavities are arranged in the tube body. The separated tube cavities can deliver different substances, and simultaneously can avoid the mixing of the different substances in the tube body. The injection holes which are arranged in the tube body of the device are respectively communicated with different tube cavities. The device can realize the following purposes: 1) the tissue patch made outside the human body is planted in the lesion position of the organism; 2) the planted tissue patch is caused to combine with the lesion position; 3) the organism lesion position can directly produce a tissue patch; 4) the problems of small tissue and cell output and difficult scale application in the tissue engineering are solved by micro delivery liquid.
