一种使用人体靶向微创定位导航床架在人体外定位的方法,主要使用所述的本发明定位导航床架及现有辅助设备:CT机、计算机、扫描仪、打印机等来完成,利用在人体上做的标记与定位导航床架相结合,通过CT机扫描人体与定位导航床架,图象输入到计算机,得到靶区区域定位或病灶实体与定位床架的空间位置数据;在手术床上再次利用人体上做的标记与定位导航床架重复定位,根据计算机输出的数据,操作定位导航床架上的导向弧转架达到靶向导航位置,进行靶向治疗或微创治疗与检查。 A method for minimally invasive targeted human bedstead navigation positioning outside the body using a navigation using the main bed frame of the present invention and the conventional auxiliary equipment: CT machines, computers, scanners, printers, etc. to complete, using in the human body and the positioning mark made navigation combined bed frame, the bed frame input body with navigation, image to the computer by a CT scanning machine to obtain the spatial position data of the lesion or target entity targeting and positioning of the bed frame; surgery bed re-use on a human body do bedstead repeated numerals navigation positioning, the data output from the computer, a pilot arc operation of the turret navigation navigation bedstead reach targeted location, or targeted therapy for inspection and minimally invasive treatment. 具体包括如下操作步骤:一、靶区区域定位1.将带有夹角为53°08'度,呈交叉状的两条z值定位线105的定位导航床架的定位底板101放置在CT扫描床上,通过CT机上的扫描仪激光定位线,调整定位底板101的位置,使扫描平面通过定位底板101上的双侧导向T型滑槽102相等的刻度线(如左+3、右+3);2.患者躺在定位底板101上达到尽量舒适稳定状态,并保证病灶位于底板101的有效刻度内;用体部固定支架107将双髋固定,记录体部固定支架107在T型滑槽102框尺的刻度;3.调整重复定位框尺201到达病灶周围层面,记录重复定位框尺201在定位底板101两侧T型滑槽102的刻度数据,再调整重复定位框尺201上三个框边上各设置的带刻度调节的定位针202深度,使针尖刚好与皮肤接触(体部侧面及上方),消毒情况下,用抽取美蓝的注射器在定位针尖与皮肤接触处注入少许美蓝作标记,然 Specifically includes the following steps: First, the target region is positioned with an angle of 1 53 ° 08 'degrees, the bed frame as a navigation two interdigitated z value of the positioning the positioning plate line 105 is placed in the CT scan 101 bed, by positioning the scanner laser line on the CT machine, the position of the base plate 101 to adjust the positioning of the scanning plane by bilateral guide plate 101 positioned on the T-type equivalent to the chute 102 ticks (+3 as left, right, +3) ; patient 2 lying on the bottom plate 101 is positioned to achieve a steady state as comfortable as possible, and to ensure that the lesion is located within the effective scale base 101;. with the body mounting bracket 107 fixed to both hips, the recording portion T type mounting bracket 107 in the chute 102 block foot scale; 3. repeating the adjustment foot 201 reaches the positioning frame 102 around the lesion scale level data, recording is repeated positioning frame 201 on both sides of the T-foot chute positioning plate 101, and then adjust the positioning frame is repeated three 201-foot frame with scale adjustable depth positioning pins 202 provided for each side of the needle tip is just in contact with the skin (body side surface and the upper portion), the disinfection, extracted with methylene blue to methylene blue as little injection syringe is positioned in contact with the skin tip mark, and then 记录此时各定位针202的刻度位置,完成体表做数个定位标记点;4.将患者送入CT扫描区,找出靶区区域;5.在邻近病灶周围进行CT连续扫描(根据病灶大小决定扫描层2-5毫米层距),待扫描图象出现后挑选所需要的扫描层面图象,中心层面图像要特别标明;6.靶区域各层CT图像以胶片或电子图形文件的方式保存,作为定位的客观依据;7.定位的相关参数记录在定位报告中。 Record the scale positions on the respective positioning pins 202, complete body made several positioning marker; 4 into the patient CT scan region, to identify target area;. 5 around the adjacent CT scanning in the lesion (according to lesion size is determined from the scanning layer of 2-5 mm layer), the selection of a desired image of the scanning slice after the scanned image appears to be particularly marked central slice images; 6 CT image in the target area of ​​each layer of film or electronic way graphics files save as positioning objective basis; 7. positioning of the relevant parameters recorded in the positioning of the report.

二.获取靶点坐标空间位置数据1.确定坐标原点:调出靶区中心层面的图片,将坐标原点定在定位底板101中心标线104处,再将水平轴线移至两条侧边定位线106上;2.获取靶点坐标:在有靶区的CT片中,从靶点出发做与坐标轴的垂直连线,靶点到X轴的直线的垂直距离为靶点相对定位底板101的Y坐标值,靶点到中心线的水平距离为靶点相对定位底板101的X坐标值;测量两条Z值定位线105间的距离为靶点相对定位底板101的Z坐标值,如图4所示(X=26.3,Y=158.2,Z=71.25);在每张有靶区的CT片中均可找到X、Y、Z的对应坐标,得到靶区相对定位底板101的空间位置。 Second location data acquisition target coordinate space 1. Determine coordinate origin: adjusting the level of the center target image, the coordinate origin is set at the center of the base plate positioning reticle 104 101, the horizontal axis and then moved to two sides of bit lines . 106; 2 acquires the target coordinates: the film has a target region in a CT, starting with the vertical axis to make the connection from the target, the target straight line perpendicular to the X-axis of the target distance is located opposite the base plate 101 Y coordinate value, the target relative to the horizontal center line of the target value of the positioning plate 101 of the X-coordinate distance; two measured value Z from the bit line 105 as a target value of the relative positioning of the Z-coordinate of the bottom plate 101, as shown in FIG 4 As shown in (X = 26.3, Y = 158.2, Z = 71.25); can be found X, Y, Z coordinates corresponding to each of the CT slice with a target to obtain target spatial position relative positioning base 101.

三.重复定位与靶向导航1.重复定位:当患者需移至手术室接受治疗时首先将定位底板101放到手术床上,按照定位报告中的各项参数,使患者再次位于定位床架的规定位置上,重复摆位误差应小于2mm;患者躺在定位底板101上后,将重复定位框尺201放到定位底板101上,使定位框尺201定位在患者做CT扫描时记录的T型滑槽102的刻度数据位置,固定好定位框尺201后,调节三个框边上的定位针202,此时患者也要慢移动体位,使针尖刚好与皮肤接触(体部两侧面及上方)到事先已用美蓝注射液器作标记处,经检查,使各定位针202的刻度位置达到CT扫描时的数据,针尖对准美蓝标记处,此时靶点的坐标值与CT扫描时所测量的坐标值一致。 Three repeat positioning navigation and targeting 1. Repeat positioning: to be moved to the operating room when the patient is first treated to position the base plate 101 into the surgical bed, according to the parameters of the positioning report, the patient again the positioning of the bed frame predetermined position, repeat setup error should be less than 2mm; after positioning the patient lying on the base 101, the scale 201 is repeated positioning frame is positioned onto the base plate 101, the positioning frame 201 is positioned a T-foot recorded when the patient CT scan done chute position calibration data 102, and fixed foot 201 is positioned after the frame, the edge of the three positioning pins adjustment block 202, then the patient needs to slow moving position, so that the needle just touches the skin (the upper and side surfaces of the body portion) to previously been marked with methylene blue at the injection device, after inspection, so that the positioning pin 202 reaches the position of the scale of the CT scan data, methylene blue tip the alignment mark, when the coordinate value CT scan target when the measured coordinate values ​​coincide.

2.靶向导航:根据靶点在中心定位线104的左或右侧,决定定位标尺安装面(如病灶在中心定位线的左侧,则将定位标尺安装在定位底板101的左侧),按所得X、Y、Z坐标数值分别调整X标尺303、Y标尺301,移动标尺连接器302,在T型滑槽102上找到Z值位置,随后通过导针引导器插入导针,到达规定的深度后则达到靶点位置,然后根据需要可进行病灶活检或粒子植入、超冷刀、射频消融等靶向治疗。 2. Targeting Navigation: The left or right side of the centrally located target line 104, determines the positioning ruler mounting surface (such as lesions on the left side of the center line of the positioning, the scale will be positioned on the left side of the positioning plate 101), obtained by X, the Y, Z coordinate values, respectively, to adjust the scale X 303, Y scales 301, connector 302 movement scale, find the value of the position Z in the T-chute 102, the guide pin is then inserted through the introducer needle guide, reaches a predetermined the depth of the target position is reached, and then need to be carried out biopsy or implantation, super cold knife, like radiofrequency ablation targeted therapy.
