[0065] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0066] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0067] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0068] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0069] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0070] Medical equipment is the basic condition for continuously improving the level of medical science and technology, and is also an important symbol of modernization. Medical equipment has become an important field of modern medicine. The development of medicine depends to a large extent on the development of instruments. Even in the development of the medical industry, its breakthrough of bottlenecks has played a decisive role. Medical devices refer to instruments, equipment, appliances, materials or other items used on the human body alone or in combination. Diagnostic equipment, treatment equipment and auxiliary equipment, such as magnetically controlled capsule gastroscopy equipment.

[0071] Medical equipment has a series of parts connected to each other through a base. The suspended part of the medical equipment will be in a vertical state under the action of gravity. Since some medical equipment is connected to the base in a fixed way, the base must be absolutely horizontal, which is usually very difficult to ensure. A base that is not absolutely horizontal will cause the overall mechanism connected to the medical equipment to generate a component force in the vertical direction, causing fatigue or even damage to the overall mechanism.

[0072] To solve the above technical problems, Figures 1 to 7 As shown, an embodiment of the present application provides a medical system, the medical system includes a medical device 2 and an adjustment device 1, the adjustment device 1 is detachably connected / or fixedly connected to the medical device 2, wherein the adjustment device 1 is used to adjust the position of the medical device 2 so that it is in a vertical state. The medical device 2 can be an X-ray diagnostic device, an ultrasonic diagnostic device, a functional inspection device, an endoscopic inspection device, a nuclear medicine device, an experimental diagnostic device, and a pathological diagnostic device. The adjustment device 1 includes a first connecting portion 11, a second connecting portion 12, a rotating shaft 13, and a locking mechanism 14; the first connecting portion 11 is used to suspend the adjustment device 1, that is, when the gravity adjustment device 1 is installed on the mounting seat, the first connecting portion 11 of the adjustment device 1 can be suspended on the mounting seat, so that the adjustment device 1 can be suspended on the mounting seat. The second connecting portion 12 is used to connect with the medical device 2, and the first connecting portion 11 and the second connecting portion 12 are rotatably connected by a rotating shaft 13, so that the first connecting portion 11 and the second connecting portion 12 can rotate relative to each other, and during the relative rotation of the two, the position of the medical device 2 connected to the second connecting portion 12 can be adjusted.

[0073] The locking mechanism 14 has a locked state and an unlocked state. When the locking mechanism 14 is in the unlocked state, the first connection part 11 and / or the second connection part 12 can rotate relative to the rotation shaft 13 to adjust the medical device 2 to a vertical position. When the locking mechanism 14 is in the locked state, the locking mechanism 14 restricts the first connection part 11 and / or the second connection part 12 from rotating relative to the rotation shaft 13 to maintain the vertical state of the medical device 2, avoid the medical device 2 from being in a tilted state after being connected to the base, and ensure the structural stability of the entire mechanism of the medical device 2.

[0074] In the embodiment of the present application, the vertical state of the medical device 2 is a state in which the medical device 2 is perpendicular to the ground. Specifically, when the medical device 2 is connected to the second connecting portion 12, the line between the connection point of the two and the center of gravity of the medical device 2 is perpendicular to the bottom surface, or the line between the connection point of the two and the center of gravity of the medical device 2 is parallel to the gravity of the medical device 2. If the medical device 2 is not in a vertical state, the locking mechanism 14 is controlled to be unlocked, and the second connecting portion 12 of the medical device 2 is driven by its own gravity to rotate so that it is adjusted to a vertical state. After the medical device 2 is adjusted to a vertical state, the locking mechanism 14 is controlled to be locked so that it maintains a vertical state to prevent it from rotating around the rotating shaft 13 due to external thrust. Reduce the risk of fatigue work or even damage of the medical device 2 caused by the component force in other directions generated when the medical device 2 is connected to work in a vertical state due to tilt.

[0075] Further, in a preferred embodiment of the present application, the first connection part 11 and the second connection part 12 can be arranged in a U-shaped structure, the first connection part 11 is located above the second connection part 12, the two are arranged vertically, the openings of the first connection part 11 and the second connection part 12 are arranged opposite to each other, and the rotating shaft 13 is located in the space surrounded by the first connection part 11 and the second connection part 12, and is rotatably connected to the two. Of course, the first connection part 11 and the second connection part 12 can also be other structural forms, as long as it can ensure that the second connection part 12 can rotate relative to the first connection part 11 and adjust the medical device 2 to a vertical state, which will not be repeated here.

[0076] like Figures 1 to 3 As shown, in a possible design, the rotating shaft 13 at least includes a first rotating shaft 131 and a second rotating shaft 132, and the first rotating shaft 131 and the second rotating shaft 132 are perpendicular to each other and connected; the first connecting part 11 is rotatably connected to the first rotating shaft 131, and the second connecting part 12 is rotatably connected to the second rotating shaft 132, so that the first connecting part 11 and the second connecting part 12 are connected and can rotate relative to each other; when the locking mechanism 14 is in an unlocked state, the second connecting part 12 can rotate around the first rotating shaft 131 or the second rotating shaft 132, and the second connecting part 12 is connected to the medical device 2, so that the medical device 2 can rotate around the first rotating shaft 131 or the second rotating shaft 132, so as to adjust the position of the medical device 2. Moreover, in a preferred embodiment, the first rotating shaft 131 is vertically connected to the second rotating shaft 132, so that the medical device 2 can be adjusted in the front-back and left-right positions. Compared with the first rotating shaft 131 and the second rotating shaft 132 intersecting at other angles, the range of the medical device 2 along its circumferential adjustment position is increased. Of course, the first rotating shaft 131 and the second rotating shaft 132 may also intersect at other angles.

[0077] After the medical device 2 is completely adjusted, the plane formed by the first rotation axis 131 and the second rotation axis 132 may be perpendicular to the vertical direction, or may intersect the vertical direction at other angles.

[0078] like Figure 1 and Figure 2 As shown, in a possible design, a locking mechanism 14 is installed between the first connection part 11 and the second rotating shaft 132; one end of the locking mechanism 14 is rotationally connected to the first connection part 11, and the other end of the locking mechanism 14 is rotationally connected to the second rotating shaft 132; when the locking mechanism 14 is in a locked state, it can limit the second connection part 12 from rotating around the first rotating shaft 131, so as to limit the second connection part 12 from rotating relative to the first connection part 11, thereby limiting the rotation of the medical device 2; when the locking mechanism 14 is in an unlocked state, the second rotating shaft 132 can rotate relative to the first connection part 11, so that the second connection part 12 can rotate around the first rotating shaft 131, thereby adjusting the position of the medical device 2.

[0079] like Figure 1 and Figure 3 As shown, further, a locking mechanism 14 is also installed between the second connecting part 12 and the first rotating shaft 131; one end of the locking mechanism 14 is rotationally connected to the second connecting part 12, and the other end is rotationally connected to the first rotating shaft 131; when the locking mechanism 14 is in a locked state, it can limit the second connecting part 12 from rotating around the second rotating shaft 132, so as to limit the second connecting part 12 from rotating relative to the first connecting part 11, thereby limiting the rotation of the medical device 2; when the locking mechanism 14 is in an unlocked state, the second connecting part 12 can rotate relative to the first rotating shaft 131, so that the second connecting part 12 can rotate around the second rotating shaft 132 to adjust the position of the medical device 2.

[0080] Furthermore, the locking mechanism 14 between the first connecting portion 11 and the second rotating shaft 132 and the locking mechanism 14 between the second connecting portion 12 and the first rotating shaft 131 can be in an unlocked state or a locked state at the same time, so as to adjust the position of the medical device 2 more quickly.

[0081] For example, the locking mechanism 14 between the first connection part 11 and the second rotating shaft 132 and the locking mechanism 14 between the second connection part 12 and the first rotating shaft 132 are opened at the same time, and the medical device 2 is driven by its own gravity to rotate the second connection part 12 around the first rotating shaft 132 to achieve the position adjustment of the medical device 2 along the direction of the second rotating shaft 132. At the same time, the medical device 2 is driven by its own gravity to rotate the second connection part 12 around the second rotating shaft 132 to achieve the position adjustment of the medical device 2 along the direction of the first rotating shaft 132, so that the medical device 2 can be quickly adjusted to a vertical state; if only one of the locking mechanisms is opened each time, the medical device is only adjusted in one direction, and multiple adjustments may be required to reach the vertical state.

[0082] like Figures 1 to 3As shown, in a possible design, the first rotating shaft 131, the second rotating shaft 132, the first connecting part 11 and the second connecting part 12 are all connected with the hinge seat 15, and the corresponding locking mechanism 14 is rotatably connected with the hinge seat 15. In the embodiment of the present application, the locking mechanism 14 is rotatably connected with the first connecting part 11, the second connecting part 12, the first rotating shaft 131 and the second rotating shaft 132 through the hinge seat 15, wherein the hinge seat 15 is fixedly connected with the first connecting part 11 and the second connecting part 12, and the hinge seat 15 is rotatably connected with the first rotating shaft 131 and the second rotating shaft 132, so as to ensure that when the second connecting part 12 rotates around the first rotating shaft 131, the first rotating shaft 131 and the hinge seat 15 installed thereon can rotate relative to each other, so that when the second connecting part 12 rotates around the second rotating shaft 132, the second rotating shaft 132 and the hinge seat 15 installed thereon can rotate relative to each other. It is worth mentioning that in other possible designs of the present application, one end of the locking mechanism 14 is connected to the first connecting part 11 through the hinge seat 15, and the other end is connected to the second connecting part 12 through the hinge seat 15, so that the first connecting part 11 and the second connecting part 12 can rotate relative to each other.

[0083] like Figure 4 and Figure 6 As shown, in a possible design, the locking mechanism 14 includes a limiting portion 141, a first locking portion 142 and a second locking portion 143, one of the first locking portion 142 and the second locking portion 143 is connected to the first connecting portion 11 or the second connecting portion 12, and the other is connected to the rotating shaft 13; the first locking portion 142 is provided with an accommodating cavity 142a, and at least part of the second locking portion 143 can move along the accommodating cavity 142a, so that the locking mechanism 14 is in an unlocked state; the limiting portion 141 is used to limit the relative movement of the second locking portion 143 and the first locking portion 142, so that the locking mechanism 14 is in a locked state. In the embodiment of the present application, the second locking portion 143 can move along the accommodating cavity 142a, so that the length of the locking mechanism 14 can be changed, so that the second connecting portion 12 can rotate around the first rotating shaft 131 or the second rotating shaft 132. At this time, the locking mechanism 14 is in an unlocked state; the second locking portion 143 is limited to move along the accommodating cavity 142a by the limiting portion 141 to maintain the length of the locking mechanism 14, thereby limiting the second connecting portion 12 from rotating around the first rotating shaft 131 or the second rotating shaft 132. At this time, the locking mechanism 14 is in a locked state.

[0084] Specifically, when the medical device 2 is in a tilted state relative to the vertical direction, the locking mechanism 14 is controlled to be in an unlocked state. The medical device 2 can drive the second connecting part 12 to rotate around the first rotating shaft 131 or the second rotating shaft 132 under the influence of its own gravity, and a certain thrust or pulling force is applied to the first locking part 142 or the second locking part 143 of the locking mechanism 14, so that the second locking part 143 moves relative to the accommodating cavity 142a, and the second connecting part 12 rotates relative to the first connecting part 11, thereby adjusting the medical device 2 to a vertical state. After the locking mechanism 14 is adjusted to a vertical state and is stationary, the locking mechanism 14 is controlled to be in a locked state, and the second locking part 143 is limited to move along the accommodating cavity 142a by the limiting part 141 to limit the rotation of the second connecting part 12 relative to the first connecting part 11, so that the medical device 2 maintains a vertical state.

[0085] like Figures 4 to 7 As shown, in a possible design, a through hole 142a1 is provided on the side wall of the accommodating cavity 142a; a plurality of locking grooves 143a are provided on the side of the second locking portion 143 facing the through hole 142a1, and the plurality of locking grooves 143a are arranged along the axial direction B of the second locking portion 143; the limiting portion 141 can extend into the accommodating cavity 142a through the through hole 142a1 and cooperate with the locking groove 143a to limit the relative movement of the second locking portion 143 and the first locking portion 142. In this embodiment, the limiting portion 141 is controlled to leave the locking groove 143a so that the second locking portion 143 can move along the accommodating cavity 142a so that the second connecting portion 12 can rotate relative to the first connecting portion 11; the limiting portion 141 is controlled to extend into the accommodating cavity 142a and cooperate with one of the locking grooves 143a to limit the movement of the second locking portion 143 along the accommodating cavity 142a so as to limit the rotation of the second connecting portion 12 relative to the first connecting portion 11.

[0086] The axial direction B of the second locking portion 143 is a direction parallel to the axis of the second locking portion 143 .

[0087] Furthermore, the cross-sectional area of ​​the locking groove 143a gradually decreases from the notch of the locking groove 143a to the groove bottom direction, and the multiple locking grooves 143a are arranged in a rack structure, and the part of the structure where the limiting portion 141 cooperates with the locking groove 143a corresponds to the locking groove 143a, so that the limiting portion 141 can extend into the locking groove 143a to ensure the working reliability of the locking mechanism 14. Of course, the shapes of the locking groove 143a and the limiting portion 141 are not limited to this, as long as the relative movement between the first locking portion 142 and the second locking portion 143 can be controlled by the cooperation between the two, and no further description is given here.

[0088] like Figure 4 and Figure 6As shown, in a possible design, the locking mechanism 14 further includes a valve 144, and the valve stem of the valve 144 is the limiter 141. The valve 144 controls the valve stem to move along the through hole 142a1, insert into or leave the locking groove 143a, and realize the locking state or unlocking state of the locking mechanism 14.

[0089] Furthermore, the valve 144 may be a solenoid valve, which is mounted on the outer wall of the first connecting portion 142 and can control the valve stem to move along the through hole 142a1. When the solenoid valve is opened, the valve stem is controlled to move along the through hole 142a1 in a direction away from the locking groove 143a to leave the locking groove 143a, so that the locking mechanism 14 is unlocked. After the solenoid valve is closed, the valve stem moves along the through hole 142a1 in a direction close to the locking groove 143a and cooperates with one of the locking grooves 143a to lock the locking mechanism 14. It is worth mentioning that in other possible designs, the limiting portion 141 and the valve stem are independent components, and the limiting portion 141 can be driven to move by the valve stem. Of course, the valve 144 may also be other types of valves, and the structural form of the limiting portion 141 is not limited in this embodiment.

[0090] like Figure 4 and Figure 6 As shown, in a possible design, the side wall of the accommodating cavity 142a is provided with a recessed portion 142a2, and the length of the recessed portion 142a2 extends along the axial direction B of the first locking portion 142; the second locking portion 143 is provided with a protruding portion 143b, at least part of the protruding portion 143b is located in the recessed portion 142a2, and can move in the recessed portion 142a2, and the two side walls of the recessed portion 142a2 along the axial direction B of the first locking portion 142 are used to limit the movement distance of the protruding portion 143b. In the embodiment of the present application, the protruding portion 143b can move in the recessed portion 142a2, and the protruding portion 143b is fixedly connected to the first locking portion 142, so that the length of the recessed portion 142a2 is the range of movement of the second locking portion 143 relative to the first locking portion 142, so as to limit the movement distance of the protruding portion 143b, so as to prevent the second locking portion 143 from moving too much and escaping from the accommodating cavity 142a of the first locking portion 142. Furthermore, the length of the recessed portion 142a2 is the rotation range of the medical device 2, ensuring that the rotation angle of the medical device 2 is within a controllable range, thereby reducing damage to the device or personnel caused by excessive rotation of the medical device 2.

[0091] like Figure 4 and Figure 6 As shown, in a possible design, along the axial direction B of the first locking portion 142, the size of the recessed portion 142a2 is less than or equal to the length formed by the arrangement of multiple locking grooves 143a, so as to prevent the second locking portion 143 from moving too far, causing the limiting portion 141 to have no matching locking groove 143a after extending into the accommodating cavity 142a, colliding with the side wall of the second locking portion 143, and failing to lock the locking mechanism 14.

[0092] Furthermore, the locking mechanism may also be other structural forms, such as a hydraulic cylinder, a pneumatic cylinder, etc. Taking a hydraulic cylinder as an example, the piston rod of the hydraulic cylinder can move along the cylinder body, and the cylinder body and the piston rod are respectively connected to the first connecting part or the second connecting part and the rotating shaft.

[0093] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
