Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a highly safe orthopedic bone drilling device. Background technique [0002] In clinical medicine, fracture is a common bone trauma disease, and the most common way to treat fractures is to implement internal fixation surgery, that is, to connect the bones with bone plates and steel nails. After healing, the bone nails need to be removed. Bone drills are often needed. Bone drills are a commonly used medical device. The treatment process of patients is an extremely important process. The performance of various medical devices in the treatment also determines whether the patient's treatment effect is good or bad. The traditional bone drill has the defects of cumbersome use and poor flexibility, and cannot better meet the various necessity requirements of medical staff in the treatment process. Every time drilling or taking nails, it is necessary to move the patient's limbs,...

[0002] In clinical medicine, fracture is a common bone trauma disease, and the most common way to treat fractures is to implement internal fixation surgery, that is, to connect the bones with bone plates and steel nails. After healing, the bone nails need to be removed. Bone drills are often needed. Bone drills are a commonly used medical device. The treatment process of patients is an extremely important process. The performance of various medical devices in the treatment also determines whether the patient's treatment effect is good or bad. The traditional bone drill has the defects of cumbersome use and poor flexibility, and cannot better meet the various necessity requirements of medical staff in the treatment process. Every time drilling or taking nails, it is necessary to move the patient's limbs, which is very difficult to use. Inconvenient, this not only increases the difficulty of the doctor's work, but also increases the pain of the patient, because the bone drill generates vibration when drilling the bone, so the doctor is very unstable when holding the bone drill to drill the bone, which increases the pain of the patient and increases the pain of the patient.
