Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a support arm and ultrasonic imaging equipment. Background Art

[0002] Most control panels for ultrasound imaging devices currently on the market can be raised and lowered within a certain range to meet user requirements. In manual lifting systems for ultrasound imaging devices, the control panel is typically connected to a support arm, and a self-locking gas spring or other energy-storing elastic member is used to raise and lower the control panel. This is achieved by controlling the opening and closing of the gas spring valve via the control panel's handle, allowing the support arm to raise and lower the control panel and lock it. When the handle is pulled, the gas spring valve opens, allowing the control panel to be raised and lowered easily. When the handle is released, the gas spring valve closes and locks the self-locking gas spring, allowing it to withstand greater loads.

[0003] In related technologies, the supporting force value of the energy storage elastic member is generally adapted to the gravity of the control panel, so that the force applied by the staff to operate the control panel to raise or lower the control panel will not be too large. However, since the supporting force value of the energy storage elastic member is not constant, during mass production, the supporting force values ​​of different energy storage elastic members often fluctuate within a certain tolerance range, such as ±80N. In this case, it is difficult to achieve a relatively ideal match between the supporting force value of the energy storage elastic member and the gravity of the control panel, which affects the user experience of the ultrasonic imaging equipment.

[0074] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0075] It should be noted that when an element is referred to as being "fixed to" or "set to" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0076] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0077] Reference within the specification of this application to "one embodiment," "some embodiments," or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in additional embodiments," and so on, in various places in the specification are not necessarily all referring to the same embodiment, unless otherwise specifically specified. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0078] In order to illustrate the technical solutions of the present application, the following will be described in conjunction with specific drawings and embodiments.

[0079] In the related art, the support force value of the energy storage elastic member is generally matched with the gravity of the control panel, so that the force of the operator operating the control panel to lift is not too large. However, since the support force value of the energy storage elastic member is not constant, in the process of mass production, the support force values of different energy storage elastic members often fluctuate within a certain tolerance range, such as ±80N. In this case, it is difficult to match the support force value of the energy storage elastic member with the gravity of the control panel, which affects the use experience of the ultrasonic imaging device.

[0080] In view of this, the present application provides a support arm and an ultrasonic imaging device. Since the energy storage elastic member has a first part and a second part, the first part is hinged to the first joint, and the second part is hinged to the second joint, the energy storage elastic member can apply a first force to the first joint, which is directed from the second part to the first part, and the energy storage elastic member can apply a second force to the second joint, which is equal in size and opposite in direction to the first force, so that the support force value of the energy storage elastic member is matched with the gravity of the control panel.

[0081] In addition, since the distance between the first part and the second part is adjustable, the distance between the first part and the second part can be dynamically adjusted according to the gravity of the control panel, so that the size of the first force and the second force can be adjusted, that is, the support force value of the energy storage elastic member can be adjusted, and thus the support force value of the energy storage elastic member is matched with the gravity of the control panel, which ensures the use experience of the ultrasonic imaging device.

[0082] Please refer to Figure 1 , Figure 2 and Figure 3 , in the first aspect, the first embodiment of the present application provides a support arm 100, which can be used in an ultrasonic imaging device 1000. The ultrasonic imaging device 1000 can further include a control panel 200, a host 300, a handle 400, a display screen 500, and a caster 600, etc.

[0083] The support arm 100 comprises a first joint 10, a second joint 20, a lifting joint 30 and an energy storage elastic member 40.

[0084] One of the first joint 10 and the second joint 20 is used to be connected with the control panel 200.

[0085] For example, the first joint 10 is connected with the host 300, and the second joint 20 is connected with the control panel 200.

[0086] One end of the lifting joint 30 is hinged with the first joint 10, and the other end of the lifting joint 30 is hinged with the second joint 20.

[0087] The energy storage elastic member 40 has opposite first and second parts 41 and 42, the first part 41 is hinged with the first joint 10, the energy storage elastic member 40 is used to apply a first action force to the first joint 10, the first action force is directed from the second part 42 to the first part 41, the second part 42 is hinged with the second joint 20, the energy storage elastic member 40 is used to apply a second action force to the second joint 20, the second action force is equal in size and opposite in direction to the first action force, and the distance between the first and second parts 41 and 42 is adjustable.

[0088] The energy storage elastic member 40 can be a gas spring, a mechanical spring or the like, the energy storage elastic member 40 can be arranged inside the lifting joint 30, the first part 41 can be provided with a release element, and the release element is hinged with the first joint 10. The support force value of the energy storage elastic member 40 is specifically represented by the first action force and the second action force. The direction of the first action force can be along the direction indicated by the arrow h in the middle, and the direction of the second action force can be along the direction indicated by the arrow i in the middle. Figure 3 Figure 3

[0089] Due to the existence of the first action force and the second action force, the second joint 20 can maintain a preset posture relative to the first joint 10, so that the control panel 200 can maintain a preset posture.

[0090] When a large number of mechanical arms are assembled, the support force value of each energy storage elastic member 40 can be dynamically adjusted according to the gravity of the control panel 200, that is, the distance between the first and second parts 41 and 42 is dynamically adjusted according to the gravity of the control panel 200, so as to adjust the size of the first action force and the second action force, so as to adjust the support force value of the energy storage elastic member 40, so that the support force value of the energy storage elastic member 40 is more ideally matched with the gravity of the control panel 200, and a better control feeling of the control panel 200 is obtained, and an excellent use experience value is created for the ultrasonic diagnosis and treatment equipment.

[0091] ​​It can be learned from the above that the support arm 100 provided by the embodiment of the application can apply the first joint 10 with the first action force directed from the second part 42 to the first part 41 through the energy storage elastic member 40, and can apply the second joint 20 with the second action force equal in size and opposite in direction to the first action force through the energy storage elastic member 40, so that the support force value of the energy storage elastic member 40 matches the gravity of the control panel 200.

[0092] In addition, since the distance between the first part 41 and the second part 42 is adjustable, the distance between the first part 41 and the second part 42 can be dynamically adjusted according to the gravity of the control panel 200, so that the size of the first action force and the second action force can be adjusted, that is, the support force value of the energy storage elastic member 40 can be adjusted, and then the support force value of the energy storage elastic member 40 is more ideally matched with the gravity of the control panel 200, thereby ensuring the use experience of the ultrasonic imaging equipment 1000.

[0093] The first joint 10 includes a first main part 11 and an adjusting element 12, the adjusting element 12 is hinged with the first part 41, and the adjusting element 12 is movable relative to the first main part 11 to increase or decrease the distance between the first part 41 and the second part 42.

[0094] By adopting the above scheme, the adjusting element 12 can be moved relative to the first main part 11 to increase or decrease the distance between the first part 41 and the second part 42, and then the size of the first action force and the second action force can be adjusted.

[0095] It should be noted that the adjusting element 12 can be connected with the first main part 11 in a sliding manner or a rotating manner, etc. The adjusting element 12 can be arranged in the interior of the first main part 11.

[0096] For example, the lifting joint 30 includes two connecting components 301, the two connecting components 301 are arranged in parallel and are spaced apart, the energy storage elastic member 40 is located between the two connecting components 301, one end of the connecting component 301 is hinged with the first joint 10, and the other end of the connecting component 301 is hinged with the second joint 20.

[0097] By adopting the above scheme, the energy storage elastic member 40 can be arranged in the interior of the lifting joint 30.

[0098] It can be understood that the two connecting components 301, the first joint 10 and the second joint 20 can form a parallelogram structure.

[0099] In the first embodiment, the first joint 10 further comprises a first connecting shaft 13, the first connecting shaft 13 is rotationally connected with the first body member 11, the adjusting element 12 is threadedly connected with the first connecting shaft 13, by rotating the first connecting shaft 13 relative to the first body member 11, the adjusting element 12 can be moved relative to the first body member 11.

[0100] By adopting the above scheme, only by rotating the first connecting shaft 13 relative to the first body member 11, the adjusting element 12 can be moved relative to the first connecting shaft 13, i.e. the adjusting element 12 is moved relative to the first body member 11, so that the size of the first force and the second force can be adjusted, and the operation is simple and convenient.

[0101] Optionally, the first connecting shaft 13 can be used as an adjusting shaft, and is rotationally connected with the first body member 11 through a bearing or the like.

[0102] In order to rotate the first connecting shaft 13 relative to the first body member 11 more labor-saving, the arrangement direction of the first part 41 and the second part 42 is not parallel to the axis of the first connecting shaft 13.

[0103] In this way, when the first connecting shaft 13 is rotated relative to the first body member 11, the force exerted by the first force on the first connecting shaft 13 through the adjusting element 12 can be reduced, so that the friction between the adjusting element 12 and the first connecting shaft 13 when the first connecting shaft 13 is rotated relative to the first body member 11 can be reduced, i.e. the first connecting shaft 13 can be rotated relative to the first body member 11 more labor-saving.

[0104] For example, the adjusting element 12 can be moved relative to the first connecting shaft 13 along the directions indicated by the arrow j and the arrow k, and the arrangement direction of the first part 41 and the second part 42 can be the direction indicated by the arrow i. Figure 3 Figure 3 For example, the adjusting element 12 can be moved relative to the first connecting shaft 13 along the directions indicated by the arrow j and the arrow k, and the arrangement direction of the first part 41 and the second part 42 can be the direction indicated by the arrow i.

[0105] Please refer to Figure 2 , Figure 3 and Figure 4 In the first embodiment, the support arm 100 further comprises an adjusting wrench, the first connecting shaft 13 is provided with an adjusting part 131, the adjusting wrench is used to be detachably connected with the adjusting part 131 to drive the first connecting shaft 13 to rotate relative to the first body member 11.

[0106] By adopting the above scheme, the adjusting wrench can be used to be detachably connected with the adjusting part 131 to drive the first connecting shaft 13 to rotate relative to the first body member 11, so that the first connecting shaft 13 can be rotated relative to the first body member 11 more conveniently.

[0107] Optionally, the adjusting part 131 can be a groove or a protrusion or the like. The adjusting part 131 is located outside the first body member 11.​

[0108] For example, the adjusting part 131 can be a hole in hexagonal prism shape, and the adjusting wrench can be an outer hexagonal wrench.

[0109] Please refer to Figures 2 to 7 In the first embodiment, the support arm 100 further comprises a fixing base 50 and a linear locking mechanism 60, the first joint 10 is connected with the fixing base 50, and the first joint 10 is movable in a linear direction relative to the fixing base 50, at least one of the first joint 10 and the fixing base 50 is connected with the linear locking mechanism 60 in a detachable manner, so as to limit the position of the first joint 10 in the linear direction relative to the fixing base 50.

[0110] By using the above scheme, the position of the lifting joint 30, the second joint 20 and the control panel 200 in the linear direction can be adjusted by moving the first joint 10 in the linear direction relative to the fixing base 50, so that the support arm 100 has more degrees of freedom, and the use of the control panel 200 is facilitated.

[0111] It can be understood that the fixing base 50 can be connected with the main machine 300. The first joint 10 can be connected with the fixing base 50 through a connecting part 52, and the connecting part 52 is located at a lower position of the first joint 10.

[0112] Among them, one of the fixing base 50 and the first joint 10 is provided with a plurality of movement cooperation parts 51, the plurality of movement cooperation parts 51 are arranged at intervals in the linear direction, the other of the fixing base 50 and the first joint 10 is connected with the linear locking mechanism 60, and the linear locking mechanism 60 can be detachably connected with different movement cooperation parts 51.

[0113] In this way, by detachably connecting the linear locking mechanism 60 with different movement cooperation parts 51, the position of the control panel 200 in the linear direction can be adjusted, which is simple and convenient.

[0114] It should be noted that the movement cooperation part 51 can be a groove or a protrusion. When the movement cooperation part 51 is a groove, the linear locking mechanism 60 can be detachably inserted with different movement cooperation parts 51. When the movement cooperation part 51 is a protrusion, the linear locking mechanism 60 can be detachably sleeved with different movement cooperation parts 51.

[0115] As one of the ways that can be implemented, the fixing base 50 is provided with a plurality of movement cooperation parts 51, and the movement cooperation parts 51 are arranged as first cooperation holes; the first joint 10 is connected with the linear locking mechanism 60, and the linear locking mechanism 60 comprises a limiting pin 61, which is detachably inserted into one of the first cooperation holes.

[0116] In this way, the structure of the moving cooperation part 51 is simple, low in cost, excellent in performance and reliable, and can bring price advantage for users, and the linear locking mechanism 60 and the moving cooperation part 51 can be connected separately.

[0117] For example, the first cooperation hole can be a round hole or a waist-shaped round hole. The end of the limiting pin 61 can be provided with a fillet or an inclined angle to facilitate insertion into the first cooperation hole.

[0118] In the first embodiment, the linear locking mechanism 60 further comprises a rotating seat 62 and a first elastic member 63. The rotating seat 62 is rotationally connected with the first joint 10, the limiting pin 61 is connected with the rotating seat 62, one end of the first elastic member 63 is connected with the first joint 10, and the other end of the first elastic member 63 is connected with the rotating seat 62. When the rotating seat 62 rotates relative to the first joint 10, the first elastic member 63 is stretched under stress, and the limiting pin 61 is moved out of the first cooperation hole.

[0119] By adopting the above scheme, only the rotating seat 62 needs to be rotated relative to the first joint 10 to move the limiting pin 61 out of the first cooperation hole. At the same time, the first elastic member 63 can automatically drive the rotating seat 62 to rotate relative to the first joint 10 in the opposite direction, so that the limiting pin 61 is inserted into the first cooperation hole. The operation is simple and convenient.

[0120] It should be noted that the first elastic member 63 can be a spring or a rubber with elasticity.

[0121] Optionally, the linear locking mechanism 60 further comprises a second connecting shaft 64. The second connecting shaft 64 is connected with the rotating seat 62, and the second connecting shaft 64 is inserted into the limiting pin 61 and gap-fitted therebetween.
