【摘要】：目的:基于陀螺儀、三維手術(shù)設(shè)計(jì)軟件建立自然頭位(nature head position,NHP)記錄及轉(zhuǎn)移系統(tǒng),在手術(shù)設(shè)計(jì)軟件中將"數(shù)字頭顱"重置于自然頭位,評(píng)估該系統(tǒng)的可行性和精確度。方法:基于陀螺儀和三維編輯軟件建立自然頭位記錄及轉(zhuǎn)移系統(tǒng)。(1)通過牙合叉、面弓等裝置將陀螺儀與患者頭部固聯(lián)。患者佩戴陀螺儀裝置,通過鏡像調(diào)整頭顱位姿到自然頭位后,用陀螺儀記錄即刻頭顱的俯仰角(Pitch)、橫滾角(Roll)和側(cè)偏角(Yaw),這是實(shí)際NHP。(2)當(dāng)陀螺儀位姿為零位時(shí)(Pitch=0°,Roll=0°,Yaw=0°),進(jìn)行錐體束CT掃描,三維重建后得到標(biāo)準(zhǔn)陀螺儀模型。(3)將患者數(shù)字頭顱與標(biāo)準(zhǔn)陀螺儀模型配準(zhǔn)融合,兩物體共同旋轉(zhuǎn)至記錄的NHP位姿(Pitch、Roll,Yaw),數(shù)字頭顱在虛擬環(huán)境下重置于NHP,是為虛擬NHP。(4)采用標(biāo)準(zhǔn)立方體作為試件,將其擺放于任意位姿,分別記錄其實(shí)際位姿和虛擬位姿,進(jìn)行30次實(shí)驗(yàn),計(jì)算實(shí)際位姿與虛擬位姿的差異(ΔPitch,ΔRoll,ΔYaw),如符合正態(tài)分布,對(duì)實(shí)際位姿與虛擬位姿的3個(gè)角度分別進(jìn)行配對(duì)t檢驗(yàn),對(duì)它們的相關(guān)性進(jìn)行Pearson檢驗(yàn)。結(jié)果:陀螺儀裝置能夠記錄患者頭顱位姿,并可通過軟件將該位姿轉(zhuǎn)移至手術(shù)設(shè)計(jì)系統(tǒng)。ΔPitch=0.03°±0.28°,ΔRoll=0.03°±0.23°,ΔYaw=0.07°±0.49°,立方體實(shí)際位姿與轉(zhuǎn)換后虛擬位姿相應(yīng)角度差異均無統(tǒng)計(jì)學(xué)意義(P0.05);Pearson檢驗(yàn)得到兩者在α=0.01水平(雙向)顯著相關(guān)(r=1.00)。結(jié)論:基于陀螺儀裝置和三維手術(shù)設(shè)計(jì)軟件的自然頭位記錄、轉(zhuǎn)移系統(tǒng)精度滿足正頜外科手術(shù)設(shè)計(jì)需求,操作流程具備可行性。
[Abstract]:Aim: to establish a natural cephalic position (nature head position,NHP (natural cephalic position) recording and transferring system based on gyroscope and 3D surgical design software, and to reposition the "digital skull" into the natural cephalic position in the surgical design software, and to evaluate the feasibility and accuracy of the system. Methods: a natural head position recording and transferring system was established based on gyroscope and three-dimensional editing software. (1) the gyro was connected with the head of the patient by occlusal fork and face arch. After the patient wore a gyroscope device and adjusted the head position to the natural head position by mirror image, the pitching angle (Roll) and the lateral deviation angle (Yaw), of the immediate head were recorded by the gyroscope. The (Pitch), angle and the lateral angle (Yaw), of the immediate head were recorded by the gyroscope. This is the actual NHP. (2) when the position of the gyroscope is zero (Pitch=0 擄, Roll=0 擄, Yaw=0 擄), the cone beam CT scan is performed and the standard gyroscope model is obtained after three-dimensional reconstruction. (3) the patient's digital head is fused with the standard gyroscope model. The two objects rotate together to the recorded NHP posture (Pitch,Roll,Yaw), and the digital head is repositioned in NHP, in the virtual environment by using a standard cube as the specimen for the virtual NHP. (4) and placing it in any position. The actual and virtual positions were recorded, and 30 experiments were carried out to calculate the difference between the actual and virtual positions (螖 Pitch, 螖 Roll, 螖 Yaw), and then paired t-test was carried out on the three angles of the actual position and the virtual posture, if it was in accordance with the normal distribution. Their correlation was tested by Pearson. Results: the gyroscope can record the patient's head position and transfer it to the surgical design system by software. 螖 Pitch=0.03 擄鹵0.28 擄, 螖 Roll=0.03 擄鹵0.23 擄, 螖 Yaw=0.07 擄鹵0.49 擄. There was no significant difference between the actual posture of cube and the corresponding angle of virtual posture after transformation (P0.05). Pearson test showed a significant correlation between the two levels (r = 0. 01) (r = 1. 00). Conclusion: based on the natural head position recording of gyroscope and 3D surgical design software, the accuracy of the transfer system can meet the requirements of orthognathic surgery design, and the operation procedure is feasible.
