Embodiment

[0021] Embodiment: The surgical fixation device for the front side of the skull includes a tooth fixing groove, a fixing frame, a connecting clamping bolt base-A, a base-B, positioning pins, and positioning pin holes. Firstly, the device is 3D printed according to the shape of the patient's head. Before preparing for the craniotomy, the patient's head is placed on the base-A and base-B, and the positioning holes and positioning pins on the two connecting surfaces are used to perform 3D printing. Position and close to ensure that there is no misalignment between the two modules of the base, then use the connecting clamping bolts to connect and clamp the base-A and the base-B, and then install the fixing frame to ensure that the patient's teeth are correctly positioned in the tooth positioning groove , and then connect and clamp the fixing frame with the bottom plate by connecting the clamping bolts. Through the above correct operations, it can be ensured that there is no relati...

Abstract

The invention discloses a fixing device for craniotomy in neurosurgery, and belongs to the technical field of clinical medicine and forensic medicine inspection tools. The fixing device comprises a base-A and a base-B, wherein the two bases are combined, connected and clamped through a positioning pin and a connecting and clamping bolt; and then a fixing plate is connected with the bases, before the fixing plate is connected, teeth of a patient are well meshed with tooth fixing grooves in the fixing plate, and relative movement is avoided after fixation. After the whole fixing device is installed, six degrees of freedom of the skull of the patient in space can be achieved, namely the skull is fully restrained, and effective support is provided for the next operation. The fixing device is simple in structure, good in fixing effect and low in cost, and the time cost of a doctor can be effectively reduced; and meanwhile, the fixing device solves the problem that the risk of a traditionalhead band and screw fixing mode to a patient suffering from osteoporosis is avoided, and therefore the patient does not need to worry about the safety risk caused by osteoporosis due to the fact thatthe fixing device is mainly used for fixing the head shape and the teeth of the patient.

Description

technical field [0001] The invention relates to the field of craniocerebral surgery. It is a fixation device designed for cranial anterior face surgery, which can quickly and accurately fix the patient's skull, and ensure that craniotomy operators can accurately open the cranium, thereby ensuring smooth and efficient operation. Background technique [0002] Before neurosurgery, it is usually necessary to perform CT scan and MRI on the patient's head to determine the location of the patient's lesion, and then open it at the corresponding position of the skull to fully expose the lesion, and then the attending physician performs related operations Work. Usually, craniotomy is a difficult problem in neurosurgery, mainly because it is difficult to fix. Because of the special structure of the human brain, the choice of fixation methods is very limited, and it is difficult to ensure that the craniotomy is performed properly. When, there is a relative displacement between the cran...
