Embodiment Construction
[0033] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0034] Figure 1 to Figure 4 It is the first embodiment of the present invention, which is a structure with three lumens and three nozzle holes.
[0035] It can be clearly seen from FIG. 1 that the device includes a tube body 10 , a lumen 20 , an injection hole 40 , a head end 30 and a plunger 50 that can slide in the lumen. The device in FIG. 1 has three lumens, which are lumen 21 , lumen 22 and lumen 23 . The plunger 51, the plunger 52 and the plunger 53 can slide in the lumen 21, the lumen 22 and the lumen 23, and the plunger and the lumen are sealed. Injection hole 40 is arranged on tube body 10, and quantity is three, (other two are not shown in Fig. 1), and its position is close to this device head end 30, respectively with lumen 21, lumen 22 and lumen 23 connected. The injection hole is closed by a rubber membrane, and the injection needle...

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.
Description
Background of the invention [0001] The present invention relates to the composition of a medical device, in particular to a device for implanting a tissue patch into a damaged part of a body or directly forming a tissue patch at a damaged part of a body. [0002] Tissue engineering is to plant high-concentration tissue cells isolated in vitro on a natural or synthetic cell scaffold that has good biocompatibility and can be gradually degraded and absorbed by the human body after being cultured and expanded in vitro. Cell biocomposites (tissue patches) are implanted into the damaged parts of the body. During the process of degradation and absorption of biomaterials, the planted cells continue to proliferate and multiply, forming new corresponding tissues and organs with their original special functions and forms. To achieve the purpose of repairing trauma and reconstructing functions, so as to solve the treatment problems of dysfunction or loss caused by tissue and organ defects...
