Description

technical field [0001] The invention belongs to the technical field of bone taps, and in particular relates to a bone tap with anti-slip wires and a use method thereof. Background technique [0002] During the treatment of clinical patients in orthopedic surgery or neurosurgery, it is often necessary to use bone plates and bone screws to fix and repair bone trauma. Among them, some parts of the bone need to be pre-drilled and manually tapped before the screws can be smoothly screwed in. Especially in neurosurgery, due to the natural inhomogeneity of the density and thickness of the human skull, there is a slight difference in surgical tapping. If you are not careful, it is easy to damage the pre-drilled hole or even injure the meninges and nerve tissue, and there is a risk of causing great harm to the patient. Therefore, there are very high requirements for the depth and direction of the tapping. At the same time, the existing bone screw part is made of non-metallic materia...
