Description

Smashing device of raw material turntable structure for preparing biomedical materials

Technical Field

The invention relates to the field of preparation of biomedical materials, in particular to a crushing device with a raw material turntable structure for preparation of biomedical materials.

Background

Biomedical Materials (Biomedical Materials) are Materials used to diagnose, treat, repair, or replace damaged tissues, organs, or to enhance their function in living beings. It is the foundation of research artificial organs and medical instruments, has become an important branch of modern material discipline, and especially with the vigorous development and major breakthrough of biotechnology, biomedical materials have become hot spots for research and development by various scientists in competition.

The history of human use of biomedical materials is as long as the history of human beings. Since the existence of human beings, people are continuously struggling with various diseases, and biomedical materials are one of effective tools for people to fight against the diseases. Tracing the history of biomedical materials, ancient Egypt people used cotton fibers and horsehair as suture lines to suture wounds about 3500 A.C. These cotton fibers, horsehair, are referred to as raw biomedical materials. Indians in mexico (aztseckers) used wood chips to repair the skull on the hand. False teeth, false noses and false ears are found in the graves of China and Egypt 2500 m ago. Gold has long been used by humans to restore defective teeth. In 1588 years, the use of gold plates for the repair of jawbone was documented. In 1775, there was a record of bone fracture in the metal fixation body, and in 1800 years there were a lot of reports about the application of metal plates to fix bone fracture. In 1809, artificial planted teeth made of gold were used. In 1851, artificial denture and jawbone made of vulcanized natural rubber were used by some people. The development of new polymeric materials in the beginning of the 20 th century has prompted the start of systematic research in artificial organs, and clinical applications of artificial organs began in 1940. Due to the clinical application of the artificial organs, the life of thousands of patients is saved, the pain and the affliction of the patients and the family members caused by the disease evil are relieved, the wide attention of the medical field is aroused, and the research pace of the artificial organs is accelerated. It can be said that soybean has a substitute for artificial organs, from the tianlinggai to the toe bone, from the internal organs of the human body to the skin, from the blood to the five sense organs, except for the brain and most of the endocrine organs. According to the development history of biological materials and the characteristics of the materials, the existing materials can be divided into three generations, and pigeons of the materials have obvious characteristics and development periods thereof and represent different levels of development of biomedical materials. The medical materials used in world war before the first world in the beginning of the 20 th century can be classified as the first generation biomedical materials, the representative materials comprise gypsum, various metals, rubber, cotton and other articles, and the first generation materials are mostly eliminated by modern medicine. The development of the second generation biomedical materials is based on the hairpin of medical science, material science (especially polymer materials science), biochemistry, physics and large-scale physical testing technology. Researchers are also mostly born by material cigars or primarily by the cooperation of materials scientists and physicians. Representative materials are hydroxyapatite, tricalcium phosphate, glycolic acid, polyhydroxyethyl methacrylate, collagen, polypeptide, fibrin, etc. Like the first generation biomedical materials, the research idea of the materials is still to improve the mechanical and biochemical properties of the materials so that the materials can substitute for the biological tissues for a long time and simulate the functions of the biological tissues in the physiological environment. The third generation biomedical materials are biomedical composite materials with the functions of promoting human body self-repair and regeneration, and the concept of the biomedical materials is simplified based on the understanding of the structures and the performances of various cell tissues, growth factors, somatostatin, growth substrates and the like in organisms. They are generally composed of components with physiological 'activity' and 'inactive' components for controlling carrier, and have ideal repairing and regenerating effects. The basic idea is that the materials are endowed with specific targeted repair, treatment and promotion effects by means of compounding of the materials, fusion of the materials and living cells, hybridization of living materials and artificial materials and the like, so that pathological tissues are mainly or even completely replaced by healthy regenerated tissues. Bone Morphogenetic Protein (BMP) materials are representative materials in the third generation of biomedical materials.

Biomedical materials have been given different meanings during different historical periods. Its definition evolves with the continuous development of life science and material science. However, they all share some common features. That is, biomedical materials are artificial or natural materials that can be used alone or in combination with drugs to make parts and devices for tissue or organ treatment, augmentation or replacement without acute or chronic harm to the host during the period of effective trial use. However, since the life phenomenon is extremely complex and is a result of adapting to the needs of life in the course of millions of years of evolution, life has certain ability of precisely regulating growth, regeneration and repair, which is incomparable with all artificial organs and biomedical materials at present. Thus, current biomedical materials are far from true expectations and requirements.

The crushing device that current biomedical materials preparation was used carries out crushing separation's in-process, and the raw materials takes place the material easily after smashing and piles up on the filter, causes the jam of filter, influences the kibbling effect of raw materials and efficiency, and the practicality is not strong.
