Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a lifting device for a flat panel detector. Background Technology

[0002] A C-arm X-ray machine is a specialized piece of equipment widely used in the medical field. Its main function is to obtain clear images of the internal structures of the human body by emitting X-rays, thereby assisting doctors in making accurate diagnoses or performing surgical procedures. This equipment is typically equipped with a flat panel detector to receive X-rays and convert them into digital image signals. However, in most existing C-arm X-ray machines, this flat panel detector is generally fixedly mounted on the equipment, and its position cannot be flexibly adjusted according to actual needs. For example, in clinical use, the closer the flat panel detector is to the human body, the clearer the image displayed during surgery; while when it needs to be moved or moved across the operating table, the flat panel detector needs to be at a higher position. Summary of the Invention

[0003] The purpose of this application is to provide a lifting device for a flat panel detector.

[0004] To achieve the above objectives, this application provides the following technical solution: a flat panel detector lifting device, including a fixed base, an intermediate base fixedly connected to the fixed base, a guide sleeve fixedly fixed to the intermediate base, a guide column vertically slidably connected to the guide sleeve, a flat panel mounting plate for mounting the flat panel detector fixedly connected to the upper end of the guide column, a nut seat fixedly fixed to the intermediate base, a nut rotatably mounted on the nut seat, a lead screw threadedly connected to the nut, the upper end of the lead screw being fixedly connected to the flat panel mounting plate, and a power module capable of driving the nut to rotate on the intermediate base.

[0005] The power module includes a drive motor, a drive pulley, a driven pulley, and a timing belt. The drive motor is fixed on the intermediate seat, the drive pulley is fixed on the output shaft of the drive motor, the driven pulley is fixed on the nut, and the timing belt is sleeved between the drive pulley and the driven pulley.

[0006] A position detection plate is fixed on the plate mounting plate, an upper photoelectric sensor is fixed on the upper end of the fixing base, and a lower photoelectric sensor is fixed on the lower end of the fixing base.

[0007] A reinforcing member is also fixedly connected between the lower end of the guide post and the lower end of the lead screw.

[0008] In summary, the technical effects and advantages of this utility model are as follows:

[0009] In this invention, the opening of the C-arm is adjusted by a lifting device. When it needs to be moved or passed over the operating table, the flat panel is raised to the highest position for easy operation. During surgery, the flat panel detector can be lowered to the lowest position to get as close to the human body as possible and obtain high-definition images. Thus, both a large opening and high-definition images can be obtained. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figures 1-3 As shown, the lifting device for this flat panel detector includes a fixed base 1, an intermediate base 11 fixedly connected to the fixed base 1, a guide sleeve 5 fixedly fixed to the intermediate base 11, a guide post 7 vertically slidably connected to the guide sleeve 5, a flat panel mounting plate 3 for mounting the flat panel detector 4 fixedly connected to the upper end of the guide post 7, a nut seat 13 fixedly fixed to the intermediate base 11, a nut 14 rotatably mounted on the nut seat 13, a lead screw 8 threadedly connected to the nut 14, the upper end of the lead screw 8 fixedly connected to the flat panel mounting plate 3, and a power module capable of driving the nut 14 to rotate on the intermediate base 11.

[0017] The power module includes a drive motor 12, a drive pulley 15, a driven pulley 16, and a timing belt 17. The drive motor 12 is fixed on the intermediate seat 11, the drive pulley 15 is fixed on the output shaft of the drive motor 12, the driven pulley 16 is fixed on the nut 14, and the timing belt 17 is sleeved between the drive pulley 15 and the driven pulley 16.

[0018] A position detection plate 6 is fixed on the flat mounting plate 3, an upper photoelectric sensor 2 is fixed on the upper end of the fixing base 1, and a lower photoelectric sensor 10 is fixed on the lower end of the fixing base 1. In this embodiment, the position detection plate 6 cooperates with the upper photoelectric sensor 2 and the lower photoelectric sensor 10, which is the existing technology.

[0019] A reinforcing member 9 is also fixedly connected between the lower end of the guide column 7 and the lower end of the lead screw 8.

[0020] The flat panel detector 4 is fixed on the flat panel mounting plate 3. The drive motor 12 drives the drive wheel 15 to rotate. The drive wheel 15 drives the driven wheel 16 to rotate through the synchronous belt 17. The driven wheel 16 drives the nut 14 to rotate, thereby converting the rotational motion into linear motion on the lead screw 8, which drives the flat panel mounting plate 3 to achieve lifting and lowering motion, and thus the flat panel detector 4 is activated. In production applications, it can achieve both large opening and high-definition images.

[0021] Unlike traditional C-arms, this device is not limited by the size of the opening. The height of the plate can be adjusted to adjust the size of the C-arm opening, which can achieve a large opening for easy operation and obtain high-definition images.

[0022] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0023] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
