Description
技术领域technical field
本发明属于医疗技术领域，特别涉及一种辅助头部精准手术定位的系统。The invention belongs to the field of medical technology, in particular to a system for assisting precise surgical positioning of the head.
背景技术Background technique
在对脑部疾病患者进行脑部精准手术的时候，通常需要将患者的头部固定住，由此而产生了立体定向框架，该框架上设置有固定钉和环状或方形连接架，使用的时候，将固定钉连接在环状或方形连接架上，然后再将固定钉钉在患者头部，而后需要固定住环形或方形连接架的位置，避免该立体定向框架在使用的时候发生移位，并且在固定住患者头部后，需要用一个与主机连接的扫描图投影仪将该患者的头部扫描图片(核磁或CT图片)投影在患者头部的准确位置，以便主治医生根据该扫描图片找准患者头部病变部位，结合现有的X线/CT/核磁等图像融合技术进一步减少误差，提高立体定向手术靶点定位的精确性和手术疗效。When performing precise brain surgery on patients with brain diseases, it is usually necessary to fix the patient's head, thus resulting in a stereotaxic frame, which is provided with fixation nails and ring-shaped or square connecting frames. At the same time, the fixing nails are connected to the ring or square connecting frame, and then the fixing nails are nailed to the patient's head, and then the position of the ring or square connecting frame needs to be fixed to prevent the stereotaxic frame from shifting during use , and after fixing the patient's head, it is necessary to project the patient's head scan picture (MRI or CT picture) on the exact position of the patient's head with a scan chart projector connected to the host computer, so that the attending doctor can The picture identifies the lesion on the patient's head, combined with the existing X-ray/CT/MRI image fusion technology to further reduce errors, and improve the accuracy of stereotaxic surgery target positioning and surgical efficacy.
然而现有的立体定向框架在固定的时候通常是多名护士用手扶住来进行固定，该种方法存在以下弊端：1、人工手扶的过程中，由于人体不可能长时间保持一个姿势一动不动，因此难免会造成立体定向框架的微量偏移，从而影响手术的进展；2、由于立体定向框架具有一定重量，而且为了尽可能减小其在使用过程中的偏移，并且为了精确操作固定钉，通常需要几个护士同时手扶住立体定向框架，操作不方便，劳动成本投入大。并且现有技术中的扫描图投影仪通常安装在离手术台较远的位置，医生操作的时候不方便。Yet the existing stereotaxic frame usually is fixed by a plurality of nurses holding with hands when fixing, and there are following drawbacks in this kind of method: 1, in the process of artificial hand holding, because the human body can't keep a posture for a long time. It is not moving, so it will inevitably cause a slight deviation of the stereotaxic frame, which will affect the progress of the operation; 2. Since the stereotactic frame has a certain weight, in order to minimize its deviation during use, and to fix it for precise operation Nails usually require several nurses to hold the stereotactic frame at the same time, which is inconvenient to operate and requires a large labor cost. Moreover, the scanning image projector in the prior art is usually installed far away from the operating table, which is inconvenient for doctors to operate.
