Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a device for measuring the hole depth of a steel tube with optical fiber pressure guide wire. Background Technology
[0002] Vascular stenosis is a serious cardiovascular disease; for example, coronary artery stenosis can lead to severe consequences such as myocardial infarction. Percutaneous coronary intervention (PCI) is now widely used in clinical treatment. Before performing angioplasty or stent placement, physicians need to qualitatively or quantitatively assess the degree of vascular stenosis to help them determine whether stent placement is necessary and what size balloon or stent to choose. Current technology uses a pressure guidewire to achieve functional and imaging diagnosis of the degree of vascular stenosis.
[0003] Existing technologies cannot measure the depth of steel tubes with enlarged diameters of less than 1 mm for pressure guide wires using conventional measuring tools. To facilitate the measurement of the enlarged hole depth, we propose a device for measuring the hole depth of steel tubes for fiber optic pressure guide wires. Utility Model Content
[0004] The purpose of this invention is to provide a device for measuring the hole depth of a steel tube for optical fiber pressure guide wire, in order to solve the problem that the hole depth of a small hole diameter (less than 1 mm) in the steel tube for pressure guide wire cannot be measured using conventional measuring tools, thus facilitating the measurement of the hole depth.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for measuring the hole depth of a steel tube for optical fiber pressure guide wire, comprising a measuring device body, the measuring device body including a base, an X-slide stage mounted on the top of the base, a plug gauge fixing block driven on the top of the X-slide stage, and a plug gauge fixed on the plug gauge fixing block; a micrometer fixing block and a fixing platform are mounted on both sides of the base located on the X-slide stage, the micrometer fixing block is equipped with a micrometer, and a steel tube clamping block is installed on the fixing platform.
[0006] Preferably, the plug gauge fixing block includes a fixing block body and a pressure plate. The pressure plate is rotatably connected to the fixing block body via a rotating shaft, and the end of the pressure plate away from the rotating shaft is fixed to the fixing block body by a fastening bolt.
[0007] Preferably, the steel pipe clamp has a placement groove for placing the steel pipe to be tested, and the cross-sectional shape of the placement groove is triangular.
[0008] Preferably, it also includes a breadboard, and the main body of the measuring device is fixed to the breadboard by bolts.
[0009] Preferably, the breadboard has multiple bolt holes at equal intervals, and handles are installed on both sides of the panel.
[0010] Preferably, it also includes an XY slide stage and a display. A column is installed at the top of the XY slide stage. A fixing plate is adjustablely installed on the column. A fixing ring is installed on one side of the fixing plate. An electron microscope is installed on the fixing ring. The electron microscope is connected to the display via a data cable.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. Push the micrometer until the end face of the micrometer's push rod is flush with the end face of the steel pipe being measured. Zero the micrometer reading and continue rotating it. When the micrometer encounters resistance, the push rod end will contact the end face of the un-enlarged hole. Read the digital value on the micrometer at this point; this is the depth of the enlarged hole in the steel pipe.
[0013] 2. Since this process is not visible to the naked eye, a microscope is used to magnify the image and display it on a monitor for easy operation. The XY slide stage allows the electron microscope to easily locate the image of the above process. Attached Figure Description

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0022] Please see Figure 1-5 In this embodiment of the present invention, a device for measuring the hole depth of an optical fiber pressure guide wire steel tube includes a measuring device body 2. The measuring device body 2 includes a base 11, an X-slide 12 mounted on the top of the base 11, a plug gauge fixing block 13 driven on the top of the X-slide 12, and a plug gauge 14 fixed on the plug gauge fixing block 13. A micrometer fixing block 15 and a fixing platform 17 are mounted on both sides of the X-slide 12 on the base 11. A micrometer 16 is mounted on the micrometer fixing block 15, and the push rod end of the micrometer is in direct contact with the top of the X-slide. The micrometer is a digital micrometer. The fixed platform 17 is equipped with a steel pipe clamp 18; the steel pipe clamp 18 has a placement groove for placing the steel pipe 19 to be tested. The cross-sectional shape of the placement groove is triangular. The steel pipe clamp is a magnetic structure, which can press the steel pipe to be tested by magnetic attraction. The steel pipe to be tested is placed on the steel pipe clamp, and the micrometer is pushed so that the end face of the micrometer push rod is flush with the end face of the steel pipe to be tested. The micrometer is zeroed, and then the micrometer is rotated. When the micrometer encounters resistance, the push rod end contacts the end face of the un-enlarged hole inside. The digital value of the micrometer is then read, which is the depth of the enlarged hole in the steel pipe.
[0023] The plug gauge fixing block 13 includes a fixing block body 131 and a pressure plate 133. The pressure plate 133 is rotatably connected to the fixing block body 131 through a rotating shaft 132, and the end of the pressure plate 133 away from the rotating shaft 132 is fixed to the fixing block body 131 through a fastening bolt 134.
[0024] It also includes a breadboard 1, and the main body 2 of the measuring device is fixed to the breadboard 1 by bolts; the breadboard 1 has multiple bolt holes at equal intervals, and handles 3 are installed on both sides of the panel.
[0025] It also includes an XY slide stage 4 and a display 10. A column 5 is installed at the top of the XY slide stage 4. A fixing plate 6 is adjustablely installed on the column 5. A fixing ring 7 is installed on one side of the fixing plate 6. An electron microscope 8 is installed on the fixing ring 7. The electron microscope 8 is connected to the display 10 via a data cable 9. Since this process cannot be seen with the naked eye, the microscope is used to magnify the image and display it on the display for easy operation. The XY slide stage allows the electron microscope to easily locate the image of the above process. The XY slide stage 4 makes it easy to move the microscope 8 to the main body 2 of the measuring device.
[0026] The working principle of this utility model is as follows: Place the steel pipe to be measured on the steel pipe clamp, push the micrometer until the end face of the push rod of the micrometer is flush with the end face of the steel pipe to be measured, zero the micrometer reading, and then continue to rotate the micrometer. When the micrometer encounters resistance, the push rod end contacts the end face of the un-enlarged hole inside. At this time, read the digital value of the micrometer, which is the depth of the enlarged hole in the steel pipe.
[0027] Since this process is invisible to the naked eye, a microscope is used to magnify the image and display it on a monitor for easy operation. The XY slide stage allows the electron microscope to easily locate the image of the above process.
