Description

Technical Field

[0001] The utility model belongs to the technical field of C-arm X-ray machines, and particularly relates to a large cable test device for a small C-arm of Philips Libra. Background Art

[0002] The small C-arm, also called C-arm or C-arm X-ray machine, as the name implies, has a C-shaped frame and is used for angiography, photography, etc. in various surgeries, mainly used in orthopedic surgeries such as bone setting, reduction, and nailing.

[0003] Philips small C-arms have a long history, clear image quality, fast imaging speed, and low radiation dose, winning a large market share. Philips small C-arms usually consist of a C-arm part and an image cart part. The C-arm part includes a C-arm control part, mainly including a circuit control part, power distribution, a high-voltage generator part, and a control box drive part for the small C-electric lift. In addition, the C-arm part also includes an X-ray tube, a collimator, an image intensifier, and a camera. The image cart part includes a power distribution part, an image processing box, and a display part, and also includes optional components such as a paper printer, an image burner, and an image storage workstation.

[0004] The connection between the C-arm part and the image cart part relies on a large cable, which contains power lines, signal lines, video lines, etc. The small C-arm is used in different operating rooms, so it needs to be pushed around in different operating rooms. During the pushing process, the large cable will be pulled or continuously rubbed on the ground. Over time, the large cable is prone to problems such as broken wires and poor contact, resulting in inability to power on, no image, or various artifacts in the image. However, in many cases, it is an intermittent problem. When engineers perform on-site repairs, they do not see the fault phenomenon, and the test cannot reproduce the fault. After the engineers leave the site, the fault appears again, and it is impossible to determine a complete solution, resulting in too long repair time, incorrect replacement of parts, wasting time and parts costs, and also affecting the use of the machine for surgeries.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0018] The technical solutions of the patent of the present utility model will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be noted that for terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the utility model.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, for terms such as "installation", "connection", "coupling", etc., a broad understanding should be made. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] The working principle of the Philips mini C-arm is as follows: The power supply of the image part obtains AC 220V power from the wall socket and sends the power to the C-arm part through a large cable; the high-voltage generator in the C-arm part rectifies and inverses the alternating current and then sends the power to the combined X-ray tube in the C-arm part; the X-ray tube emits rays, and after passing through the human body, the rays enter the image intensifier, which converts the X-rays into visible light; the camera converts the visible light into a video image signal, and through the video line in the large cable, the image video signal is sent to the image processor in the image cart part; after post-processing such as edge enhancement and brightness gain, the image signal is sent to the display to display the image of the patient, and the doctor can view the patient's image in real time and perform corresponding surgeries.

[0022] The large cable test device of the Philips mini C-arm of the present utility model includes a signal line test kit and a video line test kit. Among them, the signal line test kit includes a signal line connector, a short-circuit test head, and a multimeter; the video line test kit includes a video line connector, a camera XTV8, and an image processing box.

[0023] The large cable internally contains a power line, a signal line, and a video line. The wiring diagram of the signal line is shown in the attached Figure 1 As shown. When there is poor contact or a broken line in the signal line, the machine will have the phenomenon of losing the serial number (error codes M050, M061). If it is suspected that the large cable causes the loss of the serial number, it is necessary to measure whether there is poor contact in the large cable between the C-arm part and the image cart part. Since a part of the large cable is the connection of the power supply, if they are disconnected, problems such as inability to power on will occur, and the phenomenon is relatively obvious. Therefore, only the connections between WD X8 and SHA3 X3 of the DFI in the image processing box, and between WA1 X2 and SHA1 X4 need to be focused on for inspection.

[0024] When there is poor contact or disconnection in the signal line and it is suspected that the large cable causes the loss of the serial number, it is necessary to measure whether there is poor contact in the large cable between the C-arm part and the cart image part. Check the connections between DFI WD X8 and SHA3 X3, SHA1X4, and between WA1 X2 and SHA1 X4. Connect the signal line connectors to both ends of the large cable signal line. Connect the short-circuit test heads to the signal line connectors at both ends of the large cable respectively, and at the same time connect the two wiring clips of the multimeter to the short-circuit test heads at both ends of the large cable. After connecting the multimeter, shake the large cable. If it is found that the resistance value jumps, it may be a problem with the large cable, and the large cable needs to be replaced in time.

[0025] Sometimes when the machine is exposed, there is no image or the image has artifacts. Such failures may be caused by the video line in the large cable. Refer to the attached Figure 3 and 4 , for the convenience of testing, first open the outer cover at the camera end, find the WK3 board of the camera XTV8, move the jumper W1 on the board from 2-3 (VICA) to 1-2 (TEST), and move the jumper from W2B (BLOCK) to W2A (STAIRCASE); then open the front cover of the image processing box DFI, and connect the video line connector from X6 (XTV) of the image processing box to X7 (VCR). Press the key VCR replay on the control panel of the image cart, and the test image shown in the attached Figure 5 will be displayed on the monitor. At this time, shake the large cable and check whether there is no image or image artifacts on the monitor; if there is no image or image artifacts, it may be a problem with the large cable, and this large cable needs to be replaced in time.

[0026] The large cable test device for Philips small C-arm of the present utility model can quickly and easily determine whether there are problems such as disconnection and poor contact in the large cable by using the signal line test kit and the video line test kit in combination with a multimeter. It is very useful for confirming large cable faults, can improve the detection speed and the accuracy of fault judgment, is very practical, and has a good market application prospect.
