Technical Field

The invention relates to a medical magnetic rod, in particular to a magnetic rod for cleaning magnetic foreign matters after an operation part operation.

Background

The medical magnetic rod is a common instrument used in surgical operations and is used for the surgical operation of a patient, as the instruments used in the operations are mostly metal products, metal fragments on some instruments can be peeled off unavoidably after the operations are finished, even large metal accessories such as screws, nuts and the like are peeled off at the operation positions, and the substances are left in the body of the patient and easily cause secondary diseases.

The prior commonly used medical magnetic rod is generally a structure with a rod-shaped magnetic suction head, and because the human body has different sensitivities to a magnetic field, the original biological magnetic field in the human body can be destroyed after the action of an over-strong magnetic field for a certain time, the permeability of cell membranes can be changed by micro current generated by induction, the activity of certain enzymes can be seriously destroyed, and the phenomena of dizziness and vomiting can be generated by the human body; in addition, for some special people, such as fracture patients, metal fixing needles may be arranged at affected parts, the fixing needles can be easily loosened after the excessively strong magnetic field is left for a long time, and the bone recovery is not facilitated, and for patients with cardiac pacemakers implanted in vivo, the excessively strong magnetic field can interfere with the positioning of the pacemakers when the excessively strong magnetic field is left for a long time. Therefore, the magnetism of the conventional magnetic rod is not too strong, and when the magnetic rod is used, only some light metal fragments can be absorbed generally, but for large metal accessories such as screws and nuts, the conventional magnetic rod only can play a role of sensing and is difficult to directly suck out, and more, the conventional magnetic rod still needs auxiliary tools such as tweezers to clamp the metal fragments after being found in place; in addition, because the muscle tissue regularity of the operated part after the operation is poor, the muscle tissue regularity is accompanied with human tissues such as muscle and membrane, the difficulty of absorbing large metal accessories such as screws and nuts is increased, and the movement of the magnetic rod at the operated part is inconvenient.

Therefore, the existing medical magnetic rod has the problems that large metal accessories such as screws and nuts falling off at an operation position are not easy to take out at one time, the movement at the operation position is inconvenient, and the body damage to special people is easy to cause.
