The invention relates to a grafting method. The grafting method includes the following steps that a stock and a scion are selected, wherein the stock which strongly grows and is free of plant diseases and insect pests is selected, and a branch which is thick and strong in young stem, appropriate in seedling height and free of plant diseases and insect pests is selected to serve as the scion; disinfection is carried out, wherein the stock and the scion are disinfected; grafting, wherein a cut-grafting method is adopted for grafting, and the specific operation steps include that the stock is saw off to form a smooth section, notching is carried out vertically downwards along the side wall of the section, the scion is then inserted into a notch, and forming layers of the stock and the scion are aligned; wound treatment is carried out, wherein the side wall of the stock is tied with insulated rubber tape, and the section is covered with tinfoil; after-grafting management is carried out, wherein a grafted seedling obtained after wound treatment is wrapped with a plastic film, cultivation is carried out under the shading condition, and a nutrient solution is sprayed at regular intervals; and the formed seedling is removed out of a garden, wherein the grafted seedling obtained after after-grafting management is removed out of the garden for transplanting. By means of the grafting method, using of plastic strips in the traditional bundling process is avoided, and the survival rate of the grafted seedling is obviously improved while the grafting wound healing speed is increased.

The invention discloses a dental implant micro-electrical stimulation healing device. The device comprises an adjustable constant-voltage circuit which is used for transmitting constant voltage to an electrode, an adjustable constant current circuit which is used for transmitting constant current to the electrode, a singlechip which is used for controlling to selectively use the adjustable constant voltage circuit or the adjustable constant current circuit, adjusting the output voltage of the adjustable constant voltage circuit, adjusting the output current of the adjustable constant current circuit, and controlling the set working time of the healing device, a power supply which is used for supplying power to the singlechip, and an electrode which comprises a cathode and an anode and is used for leading out voltage or current output from the adjustable constant voltage circuit or the adjustable constant current circuit and respectively supplying voltage or current to a dental implant and human skin or soft tissue, wherein the cathode is fixed on the dental implant. According to the healing device, stem cell migration can be effectively improved, healing of bone and soft tissue on the periphery of the dental implant and combination of the bone and soft tissue with the dental implant can be promoted, quick healing of the dental implant can be effectively promoted, and the healing period can be remarkably shortened. The healing device is simple in structure, easy to operate and convenient to use.

The invention relates to a porous bacterial cellulose skin repair material with a density structure and a preparation method thereof. The porous bacterial cellulose skin repair material with the 'upper dense and lower loose' structure similar to human skin is prepared by controlling the culture condition of bacterial cellulose and adding sustained-release microspheres in the culture process. A loose layer is tightly combined with a dense layer, so that obvious physical layering is avoided, and the structural continuity is good; and gradient changes of the structures are produced in the loose layer and the dense layer, and multiple pores distributed uniformly are formed in the loose layer, so that the upper dense and lower loose gradient structure of the human skin is simulated to the utmost degree. Cells easily enter the material, the healing period of a wound is obviously shortened, and proliferation of healed scars is effectively reduced; and good air permeability and water holding property of the bacterial cellulose are kept, the wound surface can be kept in a wet environment, and healing of the wound surface is facilitated. The forming process is simple, the culture period is short, the preparation process is environment-friendly, simple, convenient and quick, and the preparation cost is low.

The present invention relates to medical equipment, and is especially one tubular intramedullary nail for fixing bone fracture. It consists of static nail, dynamic nail, elastic element and cylindrical pin, the elastic element and the cylindrical pin are mounted separately in the blind hole in the end of the static nail, and the cylindrical pin is mounted inside the hole in the dynamic nail in interference fit. The structure has the obvious advantages of constantly existing elastically axial pressurizing effect and stimulating effect on the fracture section produced during fixing the fracture and thus short fracture healing period and less pain of the patient.

The invention relates to the technical field of medicine and pharmacology, in particular to an antibacterial healing-promoting nanofiber scaffold and a nanofiber scaffold patch prepared from the same. The antibacterial healing-promoting nanofiber scaffold comprises polyvinyl alcohol, silk fibroin, carboxymethyl cellulose and an antibacterial traditional Chinese medicine composition; and a nanofiber membrane with the fiber diameter of 100nm-500nm is prepared from the raw materials by adopting an electrostatic spinning method, and the nanofiber membrane is subjected to physical crosslinking treatment to prepare the antibacterial healing-promoting nanofiber scaffold. The nanofiber scaffold patch prepared from the nanofiber scaffold can remarkably improve the wound seepage absorption performance, a slowly-formed gel layer is applied to the wound, the minimum change of the microenvironment in the wound healing process can be guaranteed, drug slow release is facilitated, the healing period is shortened, and especially during change, secondary damage to the wound is avoided.

The invention discloses an orthopedic implanted device provided with a copper-bearing coating. Copper-bearing microspheres, which are different in concentration, are immobilized / dispersed into a polymer carrier on the surface of the orthopedic implanted device in a certain mode by a gradient, so that bio-functionalization of the orthopedic implanted device is achieved, wherein the functional copper-bearing microspheres can be immobilized in such modes as chemical grafting, physical blending, electrostatic interaction and the like. The orthopedic implanted device provided with the bio-functional copper-bearing coating, as being implanted into a body, can promote bone tissue healing, promote angiogenesis and inhibit bacterial infection, so that a problem on infection caused by implantation of the orthopedic implanted device can be avoided and the healing of damaged bone tissues can be accelerated.

The present invention relates to a kind of bioactive glass, bioactive glass gel and its preparation method and application. The preparation method of the bioactive glass comprises the following steps: silica gel, sodium nitrate, triethyl phosphate, calcium nitrate tetrahydrate and The templating agent is sequentially added to the hydrochloric acid aqueous solution, placed in an environment of 55°C-65°C, and stirred to obtain a sol; the sol is aged in an environment of 55°C-65°C to obtain a wet gel; the wet gel is placed in 100 Dry at ℃-110℃ to obtain xerogel; roast the xerogel at 450-550℃ to obtain a semi-finished product; pulverize the semi-finished product by airflow to obtain nano-scale bioactive glass. The bioactive glass prepared by the preparation method of the bioactive glass has nanoscale size and high activity, and at the same time, the heat treatment temperature can be controlled below 600° C., thereby saving energy consumption.
