technical field

Background technique

When medical staff use medical instruments with display equipment (such as ultrasonic diagnostic instruments), they are often required to adjust the display equipment and The positional relationship between the operator's sight requires the display device to be able to move flexibly, that is, it can realize operations such as up and down, front and rear movement, left and right movement, and left and right rotation, so that the display device can be freely adjusted according to the operator's intention. Generally, desktop ultrasonic diagnostic instruments can be divided into the following categories in terms of motion form: the first one is composed of a horizontal link and a support arm with lifting function. The horizontal link is hinged with the support arm through a rotating joint, and the support arm is installed on the On the host body, such as the structure used in the desktop ultrasound equipment, the floating operation in the plane is realized by rotating the joint, and the up and down movement of the support arm can realize the movement of the display device in space. The second is that the two supporting arms with lifting function are fixedly coupled in the up and down direction, and the two supporting arms are connected by a rotating joint to realize the floating operation in the plane, such as the structure used in the desktop ultrasonic equipment, plus the supporting arm The up and down movement of the display device can realize the movement of the display device in space. The third type is the disc type support arm form, which consists of two up and down opposite rotating discs and a closed system composed of two connecting rods. The connecting rods are hinged with the edge of the disc. The function of lifting and lowering is added, and the combination of the above movements can realize the movement of the equipment in the space. The fourth type is the form of flying support arm, such as the flying support arm structure used by ultrasonic equipment, which consists of a number of simplified links such as four links to form a closed system, two of which are support arms with lifting function, and the remaining three One is a horizontal connecting rod, and the connecting rods are connected by joints. The movement in the horizontal plane is realized by the closed five-link, plus the up and down movement of the lifting support arm, the combination of the above movements can realize the movement of the display device in the space.

The first implementation has a simple structure, but the operation experience is affected by the matching of the damping force value between the rotating joints, the movement range is small, the local space cannot be reached, and there is no front-to-back translation; the second implementation has a large movement range, but the operation experience is affected by the rotation. Affected by the matching of damping force values between joints, the local space cannot be reached, the volume is large, and the front and rear translations are accompanied by lifting motions, resulting in poor experience. The third type realizes the stable motion form of the disc connecting rod, which has a compact structure and a good plane floating effect, but has a small range of motion, many parts, a complex structure, and high assembly and maintenance costs. The fourth implementation method has a large range of motion and good spatial floating motion performance, but requires multiple connecting rods, a lifting support structure, and a rotating hinge between the connecting rods. There are many parts, the structure is more complex, and the assembly and maintenance costs are high.
