[0023] In order to make those skilled in the art more clearly understand the purpose, technical scheme and advantages of the utility model, the utility model will be further described below in conjunction with the drawings and embodiments.

[0024] In the description of the utility model, it is understood that the orientation or position relation indicated by the terms such as "up", "down", "left", "right", "inner", "outer", "horizontal", "vertical" is the orientation or position relation shown in the drawing, and is only for the convenience of describing the utility model, and does not indicate or imply that the indicated device or element must have a particular orientation, therefore it can not be understood as the limitation of the utility model.

[0025] The utility model will be described in detail below in conjunction with the drawings: as Figure 1 The utility model discloses a structure schematic view of the detection table.

[0026] As Figure 2 The utility model discloses a structure schematic view of the detection table.

[0027] As Figure 3As shown, the cross-configuration linear guide 2 consists of an upper guide rail 21, a lower guide rail 22, and a slider 23. The upper guide rail 21 and the lower guide rail 22 are in an I-shape. The lower guide rail 22 is mounted on the testing table 1. A full-circle protractor 3 is installed at one end of the upper guide rail 21. The slider 23 is arranged between the upper guide rail 21 and the lower guide rail 22, and is locked in the recesses on both sides of the I-shaped upper guide rail 21 and the lower guide rail 22, so that the upper guide rail 21 and the lower guide rail 22 are arranged in a cross shape. A fixing hole 24 is provided on the side of the slider 23, and it is fixed by bolts 25 to secure the upper guide rail 21 and the lower guide rail 22. A rolling element (not shown in the figure) is also arranged in the groove 221 of the guide rail to achieve low-friction linear motion.

[0028] When the bolt 25 is loosened, the full-circle protractor 3 can move back and forth and left and right, thereby adjusting the relative position between the full-circle protractor 3 and the front end of the fiberoptic bronchoscope 5.

[0029] like Figure 4 As shown, the full-circle protractor 3 is a full-circle angle measuring tool, consisting of a protractor 31, a scale 32, and a fastening screw 33. The fastening screw 33 is coaxial with the protractor 31, fixing the protractor 31 and the scale 32 together. The protractor 31 is marked with a zero mark 311 and a scale 312. The scale 32 rotates around the center point of the protractor 31, and its side 321 coincides with the radius direction of the protractor 31 at any angle, used to indicate the bending angle of the fiberoptic bronchoscope 5 above.

[0030] The 312 mark on the circle is used to measure angles in degrees. Starting from the zero mark 311, which is 0°, the 312 marks are clockwise from 1° to 359° (the angle interval is 1°. For easy identification, the marks every 5° are longer than normal, and the marks every 10° are longer than the marks every 5°). In addition, the angle interval of the 312 mark can also be 0.5° or other values.

[0031] like Figure 5 As shown, the fiberoptic bronchoscope 5 is mounted on a V-shaped holder 4. The V-shaped holder 4 consists of an inverted T-shaped mounting bracket 44 and a placement bracket 45 extending from the top. The placement bracket 45 has a groove 42 for placing the fiberoptic bronchoscope 5, and a support platform 43 is provided at the end of the groove 42 to support the curved front end of the fiberoptic bronchoscope 5 and make this plane parallel to the upper plane of the protractor 31. The V-shaped holder 4 is also provided with a mounting through hole 41 for easy installation onto the testing stage 1.

[0032] The support platform 43 is made of acrylic material and is transparent, making it easy to view and adjust. The side 321 of the scale 32 is parallel to the front end 53 of the fiberoptic bronchoscope 5 in the vertical direction.

[0033] like Figure 6 As shown, the fiberoptic bronchoscope 5 consists of a main body 51, a curved section 52, and an anterior end 53. The diameter of the main body 51 is typically 5.2 mm. It is suitable for observation of lesions in the lobes, segments, and subsegments of the lungs, biopsy sampling, bacteriological and cytological examinations, and, when used with a TV system, for photography, teaching, and dynamic recording.

[0034] The upper and lower guide rails are provided with multiple threaded through holes, and the slider is also provided with corresponding upper and lower connecting through holes. The positions of the upper and lower guide rails can be adjusted by means of the threaded through holes and connecting through holes.

[0035] This invention achieves relative forward and backward, left and right movement between the fiberoptic bronchoscope 5 and the full-circle protractor 3 through the dual-axis linkage of the upper guide rail, lower guide rail, and slider. This ensures that the front end 53 of the fiberoptic bronchoscope 5 is parallel to the side surface 321 of the scale 32 in the vertical direction. The scale value 312 indicated by the scale 32 is the bending angle value of the curved part of the fiberoptic bronchoscope 5. Figure 1 As can be seen, the bending angle of the fiberoptic bronchoscope 5 is 90° at this time.

[0036] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
