正确安装定向框架是脑立体定向手术成功的重要一步。准确定位是立体定向手术及检查的关键。定向框架摆位不正、倾斜、扭曲、错位等 ,既影响 CT扫描 ,又影响靶点坐标的准确性 ,甚至妨碍手术入路。为此我们在框架固定前 ,用自制固定布带代替耳塞 ,做好摆位调整后 ,再于颅骨固定针 Proper installation of a directional framework is an important step in the success of brain stereotactic surgery. Accurate positioning is the key to stereotactic surgery and examination. Improper positioning, tilting, twisting, misalignment, etc. of the directional frame will not only affect the CT scan, but also affect the accuracy of the target coordinates, and even hinder the surgical approach. For this reason, before the frame is fixed, we replace the earplugs with self-made fixing tapes, make adjustments after the adjustment, and then fix the needles on the skull.
