Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a bone implanter for clinical treatment of bone injuries. Background Art

[0002] The bone graft used in the clinical treatment of bone injuries is a medical device used to repair and restore the function of bone structure. It is usually made of metal, bioresorbable materials or artificial bone materials. It has the functions of bone repair and reconstruction, bone support and reinforcement, promoting bone tissue regeneration and growth, and repairing bone defects. These functions help accelerate the patient's bone healing process and can accelerate the restoration of the patient's normal bone function and quality of life.

[0003] However, the insertion end of traditional bone grafting devices is mostly of fixed size. Therefore, when encountering bones of different sizes, the larger insertion end may aggravate the patient's bone injury, while the smaller insertion end may increase the difficulty of bone grafting for the user due to its smaller caliber. In addition, traditional bone grafting devices are mostly in one piece during actual use, so it is not convenient for users to disassemble and repair the bone grafting device after use, thereby reducing the flexibility of the bone grafting device when used.

[0004] Therefore, those skilled in the art provide a bone implant for clinical treatment of bone injuries to solve the problems raised in the above-mentioned background technology. Utility Model Content
