This application claims priority to Taiwan Patent Application No. 105129810, filed Sep. 13, 2016, reference of which is hereby incorporated in its entirety.
The present invention relates to a molding apparatus, and more particularly, to an autologous cell multidimensional molding apparatus.
With the advancement of medical technology, the use of artificial implants such as artificial dressings and artificial organs is becoming more frequent. Artificial dressings are commonly used in a wide range of burns or postoperative patients to replace the damaged skin, protect the wound from contaminants or bacterial infection, absorb their body fluids to keep the body moisture from escaping and promote the growth of connective tissue. Artificial organs such as artificial electronic ears or artificial blood vessels can be used to simulate and replace the function of the original organ, or semi-support with the original organ to maintain the body function.
However, artificial implants may also cause adverse reactions to the human body resulting in exclusion of the human body due to heterogeneous substances and additional immune mutex problems. Therefore, autologous cells are used as the substrate of artificial implants later.
The multidimensional molding method of autologous tissue is carried out by filling a raw material or a cell material in a bucket, putting into a raw material section of multidimensional molding apparatus and extracting from the raw material holder to perform the formation of the cells and tissues of the artificial implants.
During the process, the raw materials are easy to be contaminated because of human movement and the replacement of vessels, which results in not high implant molding yield. Besides, as multidimensional molding apparatus is in an open space, such conventional process makes the manufacture of the artificial implants susceptible to be contaminated due to persons or the environment, which further results in not high implant molding products. Therefore, how to design a cell tissue multidimensional molding apparatus that the raw materials for molding and the forming process are not contaminated by the outside world is an urgent problem to be solved now.
The above-mentioned conventional technology still has a lot of missing, and it is not a good design; therefore, it needs to be improved. In view of the above, the present invention provides an autologous cell multidimensional molding apparatus to facilitate efficient production.
An object of the present invention is to provide an autologous cell multidimensional molding apparatus. According to an embodiment of the present invention, the autologous cell multidimensional molding apparatus is used for customizing an artificial implant by using an autologous cell, which comprises a barotropic room, an autologous cell culturing module, a supplying module, a multi-axis molding module and an implant saving module. The barotropic room is used for inputting a gas having a pressure greater than an ambient pressure. The autologous cell culturing module is configured in the barotropic room and comprises a culture vessel and a feed pipe, wherein the culture vessel is used for culturing the autologous cell into a cultured autologous cell, and the feed pipe is connected to the culture vessel for receiving the cultured autologous cell. The supplying module is configured in the barotropic room and comprises a peristaltic feeder and a discharge pipe, wherein the peristaltic feeder is connected to the feed pipe for receiving the cultured autologous cell and mixing the cultured autologous cell with a polymer material to be a combined autologous cell, and the discharge pipe is connected to the peristaltic feeder for receiving the combined autologous cell. The multi-axis molding module is configured in the barotropic room, and the multi-axis molding module is connected to the discharge pipe for receiving the combined autologous cell and customizing to print the combined autologous cell to the artificial implant. The implant saving module is configured in the barotropic room and is set under the multi-axis molding module for carrying and saving the artificial implant. Wherein, the feed pipe and the discharge pipe are enclosed pipelines respectively.
Furthermore, the connection between the feed pipe and the culture vessel, the connection between the peristaltic feeder and the feed pipe, the connection between the discharge pipe and the peristaltic feeder and the connection between the multi-axis molding module and the discharge pipe are enclosed pipelines respectively.
The multi-axis molding module comprises a printing material injection head, a pattern receiving element and a six-axis moving arm. The printing material injection head is connected to the discharge pipe for inputting the combined autologous cell and printing the artificial implant. The pattern receiving element is used for receiving a customized pattern, and the six-axis moving arm is electrically connected to the pattern receiving element for driving a customized printing itinerary of the printing material injection head.
Wherein, the six-axis moving arm moves in a three-dimensional space with an angular movement.
As compared to the prior art, the autologous cell multidimensional molding apparatus of the present invention uses the barotropic room to produce a production environment of pollution-free, and uses the closed connection to isolate the whole production process from the autologous cell material to the artificial implant product from the outside world, and uses the six-axis molding module to make a customized autologous cell multidimensional print to get the high yield of the customized artificial implant.
