Description

Technical Field

[0001] The utility model relates to the field of medical surgery, in particular to a nail removal structure used in medical orthopedics. Background Art

[0002] The nail remover is a tool used in various fields. Its function is to nail steel nails into corresponding positions or remove steel nails from corresponding positions. It is conducive to positioning relatively fixed parts, and can effectively ensure that the parts that need to be fixed are fixed and stable to prevent movement. It is more suitable for trauma orthopedics, and can easily position and stabilize traumatized bones to ensure that the bones heal stably within the support range.

[0003] Orthopedics mainly studies the anatomy, physiology and pathology of the musculoskeletal system. In orthopedic trauma medical surgery, the most commonly used treatment method is internal fixation surgery, which uses metal-supported bone plates and bone screws to connect the reduced bones. When the fracture site recovers, another surgery is required to remove the bone screws. Bone screws are non-active surgical metal implants for bone joining and can be used in adults and pediatric patients.

[0004] The existing nail removers for orthopedic surgery are mainly used to remove complete bone nails from bones. When the bone nails fixed on the patient's bones are broken, when the existing nail removers are used to remove the broken bone nails on the bones, it is difficult for the nail remover and the bone nails to match normally, which is easy to cause accidents when removing the broken bone nails. At the same time, the process of removing the bone nails becomes more cumbersome. The patient will feel pain when removing the nails, which will affect the nail removal process and reduce the efficiency of the operation. Utility Model Content
