[0067] In a preferred embodiment of the present application, in order to ensure that the device meets the safety requirements of medical devices, the material selection of each component fully considers biocompatibility and sterilizability. The components in the storage assembly 4, the bone powder metering assembly 3, the mixing assembly 2 and the conveying assembly 6 that are in direct contact with the bone powder and the mixture, including the isolation shell 41, the metering box 302, the mixing box 21, the rotating shaft 25, the auger 26, the crushing block 29, the conveying pipe 63, etc., are preferably made of medical-grade 316L stainless steel or medical-grade polyether ether ketone material, which can avoid material precipitation to contaminate the bone powder mixture, and at the same time resist high-temperature steam sterilization. The components subjected to mechanical stress, such as the rotating shaft 25, the auger 26 and the crushing block 29, can be made of medical-grade titanium alloy, which has high strength and excellent corrosion resistance. The elastic member 309 and the sealing gasket at each connection are preferably made of medical silicone rubber, which can withstand 134℃ high-temperature steam sterilization without deformation. The shell components such as the support seat 1 can be made of medical-grade ABS plastic or polycarbonate, which has good mechanical strength and surface cleanliness. In order to avoid the adhesion of bone powder affecting the accuracy of metering, the inner surface of the storage assembly 4, the mixing assembly 2 and the conveying assembly 6 can be sprayed with a polytetrafluoroethylene coating, and the coating thickness is controlled to be 20-50μm.

[0068] The device adopts a modular and detachable structure for easy cleaning and disinfection. The front end parts of the storage assembly 4, the bone powder metering assembly 3, the mixing assembly 2 and the conveying assembly 6 can be quickly detached through threaded connection or buckle connection, which is convenient for medical staff to clean and sterilize thoroughly. After use, the device should be rinsed with flowing water to remove residues, and if necessary, soaked in neutral enzyme cleaner for 5-10 minutes, and finally rinsed with purified water and dried. For metal components and silicone rubber sealing elements that come into contact with bone powder, high-temperature and high-pressure steam sterilization method can be used, and the sterilization parameters are temperature 134℃, pressure 210kPa, and time 5-10 minutes. For polyether ether ketone material components that are not resistant to high temperature or components with polytetrafluoroethylene coating, low-temperature hydrogen peroxide plasma sterilization method can be used, and the sterilization temperature is 45-55℃, and the time is 45-75 minutes. The shell components of the device can be wiped with ethanol or chlorine-containing disinfectant. In order to reduce the risk of cross infection, the conveying pipe 63 can be designed for one-time use, and the sealing element is recommended to be replaced regularly. The bone powder raw material should be selected from pre-packaged sterile products sterilized by γ-rays or ethylene oxide, and sterile normal saline or sterile processed autologous blood should be filled into the liquid storage tank 51.

[0069] The device is suitable for jaw bone augmentation, maxillary sinus lift, tooth extraction site preservation, implant surrounding bone defect repair and other surgical procedures. For small defects, 0.2-0.5 mL of bone powder can be taken at a time, and for large defects, multiple operations can be repeated to accumulate filling. By adjusting the knob 72, the bone powder quantity can be quickly adjusted without stopping the machine. The observation window one 44 and the observation window two 57 facilitate intraoperative inspection of the material remaining.

[0070] Those skilled in the art should understand that the above material selection, sterilization method and clinical parameters are only preferred embodiments, and can be appropriately adjusted according to actual needs without departing from the concept of the present application. For example, other medical grade materials can be selected, other sterilization methods can be selected according to the equipment conditions of medical institutions, and various parameters can be optimized according to the characteristics of different bone powder products. These changes are within the scope of protection of the present application.

[0071] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
