Description

Technical Field

[0001] The utility model relates to the technical field of X-ray imaging devices, in particular to a mobile X-ray biological imaging device. Background Art

[0002] An X-ray machine is a device that can generate X-rays. X-ray generation requires three conditions: (1) an electron source; (2) a high-speed electron flow; and (3) a target. In medicine, X-ray machines used for diagnosis are called diagnostic X-ray machines. They can perform fluoroscopy, photography, and other examinations, mainly based on the penetration, differential absorption, and fluorescence of X-rays.

[0003] Traditional mobile medical diagnostic X-ray machines come in a wide variety of styles. These can be categorized by structure into two main categories: low-power modular head-mounted machines (approximately 5 kW) and high-power standalone X-ray tube assembly machines (>32 kW). Low-power modular head-mounted machines are characterized by their relatively light weight, low manufacturing cost, and simple frame structure. Most utilize a mantis arm-like structure, allowing for detachable and portable designs. However, their disadvantages include low power, significant impact from lung respiratory movement, insufficient penetration into thick areas, and inconvenient positioning for clinical use.

[0004] The characteristics of independent X-ray tube assembly high-power machine are high power, no influence of lung respiratory movement, ability to penetrate thick parts, convenient positioning in clinical use, clear images, and the ability to meet the requirements of all parts of the body for imaging. The disadvantage is that it is relatively heavy, inconvenient to adjust its position, and the use effect is poor. Utility Model Content

[0006] The technical solution adopted by the present invention to solve its technical problems is: a mobile X-ray biological imaging device, including a workbench and an X-ray assembly, the X-ray assembly including an X-ray generator, an X-ray source and a mounting bracket, a displacement mechanism for driving the X-ray assembly to perform linear motion is provided on the end face of the workbench, the displacement mechanism includes a linear guide rail, a linear slider, a screw module and a servo motor, the linear guide rail extends along the length direction of the workbench, the linear slider is slidably matched with the linear guide rail, the screw module is transmission-connected to the linear slider, and the servo motor is drivingly connected to the screw module.

[0007] Preferably, a mounting seat fixedly connected to the end face of the linear slider is provided, and a lifting assembly for driving the X-ray assembly to move up and down is provided on the end of the mounting seat away from the linear slider. The lifting assembly includes a lifting cylinder and a lifting plate, and the telescopic shaft of the lifting cylinder is drivingly connected to the lifting plate.

[0008] Preferably, the lifting plate is provided with a rotating assembly for driving the X-ray assembly to perform rotational motion, the rotating assembly comprises a rotating cylinder and a rotating shaft, and the rotating cylinder is drivingly connected to the mounting bracket via the rotating shaft.

[0009] Preferably, the X-ray generator is arranged inside the mounting bracket and is rotatably connected thereto.

[0010] Preferably, an adjustment rod is provided on one side of the X-ray generator.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By setting up a displacement mechanism for driving the X-ray component to perform linear motion, the servo motor drives the screw module to transmit the linear slider, thereby adjusting the axial displacement of the X-ray component. This can facilitate the staff to adjust the position of the X-ray component, thereby improving the work efficiency of X-ray biological imaging. BRIEF DESCRIPTION OF THE DRAWINGS
