A few days ago, the Beijing Institute of Neurosurgery, Capital Medical University, and the Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, and other research groups invented a new type of auxiliary drill for craniotomy, which can effectively solve the problem of craniotomy drilling fixtures. Problems such as skin damage and infection. The invention has been granted the “utility model patent†by the State Intellectual Property Office.
In craniotomy, the anchoring ring and the electrode cap covering it are placed on the skull to fix the electrodes, wires and catheters connected from the intracranial to the extracranial. In the past, whether it was a hand drill or an electric drill, the thread of the anchoring ring was embedded in the bone hole, but the ring part protruded outside the skull, which easily caused the patient's skin to be damaged and infected.
In view of the problems existing in the operation of the instrument, Professor Meng Fangang and other research groups continue to explore and summarize, and combined with clinical practice to invent a new type of craniotomy auxiliary drill. After the craniotomy drill penetrates the skull, the doctor uses the auxiliary drill to drill a circular groove around the bone hole for placing anchors such as anchoring rings. The auxiliary drill consists of a drill bit, a core, a drill body and a drill body joint. The drill core has a drill bit on the periphery of the core, and the drill core protrudes from the drill bit. Different parts of the auxiliary drill can be made according to the specific requirements. The parameters can be adjusted according to the actual situation, which can meet the needs of safe and convenient placement of the fixation device for craniotomy, reduce the chance of skin damage, and receive clinical Physician's respect.
