the amount of lever I is two, may first section 个操控钮4将与其连接的第一根量杆I推出腔管2以测定肿瘤的长度,再通过第二个操控钮4将与其连接的第二根量杆I推出腔管2直至拉杆9自腔管2伸出,便可同时对肿瘤的厚度及人体管腔的直径进行测量,上述二根量杆I的长度可等长或不等长;量杆I为三根时,使用的程式与前述的相同,即先推出最短的量杆I,若该量杆I的长度短于所测肿瘤的长度,再将较长的量杆I推出,若仍不适合,再将最长的量杆I推出,每根量杆I的长度不等,可扩展测量范围;量杆I为四根时,使用的程式亦与前述的相同,其使用的范围更大且更方便实用,特别适用不同粗细的人体管腔,尤其适用于因人体较粗的管腔贴壁生成的肿瘤较大而占据人体管腔内较大空间,使人体管腔的通径变为狭窄的恶劣状况,并且利用四根量杆I不同组合可同时对人体管腔的直径、肿瘤的长度、肿瘤的厚 An amount of a first control knob 4 to the root a rod connected thereto I Release 2 to determine the length of the lumen of the tumor, and then by a second amount of second control knob rod 4 connected thereto I Release lumen 2 until the lever 9 from 2 extending lumen, while the thickness of the can body lumen diameters and the tumor was measured the amount of the two rods may have a length I equal or unequal length; the amount of the rod I is three, and the program used is the same, i.e., start with I bar shortest amount, if the amount is less than the length of the rod I the measured length of the tumor, and then amount of the longer lever Release I, if we do not fit, then the longest I dipstick Release, I the length of each rod varies the amount, the measurement range can be extended; the amount of the rod I is four, the program also use the same range of a larger and more convenient and practical to use, particularly suitable for different thickness body lumen, particularly suitable for thicker because the body lumen adherent generated within the tumor is large and occupy a large space body lumen, the body lumen diameter stenosis becomes bad condition, and the amount of use of four I bar on different combinations simultaneously body lumen diameter, length, tumor thickness 度(或称高度)及人体管腔与肿瘤之间的间距进行测量;测量完毕后,操作操控钮4将量杆I完全收入腔管2内,随同内镜从人体管腔撤出,医生根据所测得的管腔直径,选用与管腔直径相配的支架置入该管腔内快速完成介入手术。 Level (or height) of the distance between the tumor and the body lumen with the measurement; After measurement, the amount of the operation control lever knob 4 I completely within the lumen revenue 2, withdrawn from the body lumen along endoscopy, according to the doctor the measured diameter of the lumen, the lumen diameter selected to match the rapid completion of the interventional procedure stent within the lumen. 用于测量支气管的直径时(图7所示),将腔管2随同气管镜导管11沿气管10送入至支气管口处,将量杆I推出腔管2,通过气管镜导管的摄像头12观察量杆I的长度标记8可测量出支气管的直径;用于测量的胆道15的直径时(图8所示),将腔管2随同肠镜13通过肠道乳头14送入至胆道15与肠道16交汇处,将量杆I推出腔管2,通过肠镜的摄像头12观察量杆I的长度标记8可测量出胆道15的直径;用于测量胃壁病变部位时(图9所示),将腔管2随同胃镜17送入胃18内发生的胃壁病变部位处,如溃疡或癌变处,将量杆I推出腔管2,通过胃镜17观察量杆I的长度标记8可测量出溃疡或癌变大小面积。 When used for measuring the diameter of the bronchus (FIG. 7), the lumen 11 of the catheter 2 together with the bronchoscope 10 into trachea along the mouth to the bronchi, the dipstick I Release 2 lumen, the catheter 12 is observed by a camera bronchoscope I mark length measuring rod 8 may measure the diameter of the bronchus; for measuring the diameter of the biliary tract 15 (FIG. 8), the lumen 13 through the intestinal colonoscopy 2 along the nipple 14 to the bile duct 15 into the gut Road junction 16 of the dipstick lumen Release I 2, I the length of the mark 15 a diameter of 8 bar biliary measurable by the camera 12 to observe the amount of enteroscopy; means for measuring gastric lesion (FIG. 9), 2 along with the endoscopic lumen 17 into the stomach wall occurs at the site of the lesion within the stomach 18, such as ulcers or cancer, the amount I bar lumen Release 2, I the length of the rod 17 through the gastroscope observations ulcer or measurable marker 8 the size of cancerous area. 根据人体病变的气道、食道、胆道、肠道、血管等人体管腔直径及肿瘤大小的不规则状态(如椭圆形、三角形、局部凹凸形等),只需通过操控手柄3将量杆I变换角度和位置便可所需测量的部位进行全方位精确测量,本发明既可与各种内镜配合使用也可单独使用,具有可控变直径的特点,操作方便、测量精度高及测量范围大。 The human disease of the airways, esophagus, biliary tract, the intestinal tract, blood vessels and other body lumen diameter and irregularity in tumor size (e.g., oval, triangular, local unevenness shape, etc.), simply by manipulating the handle lever 3 that the amount of I transformation angle and position of the desired measurement can accurately measure a full range of parts, the present invention can be used in conjunction with various endoscopic also be used alone, with a controllable variable diameter characteristics, easy operation, high measurement accuracy and measurement range Big.
