Description

Rotary linkage device of ultrasonic equipment and ultrasonic equipment

Technical Field

The application relates to a medical instrument, in particular to a structure capable of realizing synchronous linkage of a display device and a control panel.

Background

Medical personnel often require operation panel can rotate in a flexible way and face medical personnel or patient when using the medical instrument that has operation panel (taking ultrasonic diagnostic apparatus as an example), often based on the needs of operation, diagnosis, treatment when especially doing different position inspections, require that the display also can face medical personnel or patient in step simultaneously, conveniently control equipment or show diagnostic image.

A general desktop ultrasonic diagnostic apparatus is provided with a control panel, a display and a support arm assembly (hereinafter referred to as a display device). Generally, there are two common structural forms of an ultrasonic diagnostic apparatus. The first is that the control panel and the display device are fixedly integrated on a platform, and the display device is usually fixed on the control panel. When the control panel rotates, the display device can also rotate synchronously because the display device is fixed on the control panel. The second is that the control panel and the display device are independently fixed on the machine body, and the user rotates the display device and the control panel to the required positions through manual operation.

In the first solution, the control panel and the display device are fixedly integrated on a platform, and both rotate around the same axis, but the distance between the control panel and the display device is different from the rotation axis, especially the display device is usually disposed offset from the rotation axis, so the structure occupies a large volume, and the space occupied by the equipment when rotating is too large due to the fact that the distance between the outermost edge and the rotation axis is too long. In hospital use scenarios, it is often easy to bump into surrounding items (such as beds, workstations, equipment items and connecting cables) during rotation, or to have no rotating space due to the proximity of the bed to the machine. In the second scheme, after the medical staff rotates the control panel, the display still needs to be rotated, so that the operation actions of the medical staff are increased, and the user experience is poor.

Example (b):

the embodiment provides an ultrasonic device, in particular an ultrasonic diagnostic apparatus.

Referring to fig. 1, the ultrasonic apparatus includes a control panel 1, a display device 2, a rotary linkage 3, and a main unit 9. The display device 2 may include a display 21 and a display support arm assembly 22. The display 21 may employ various display devices for displaying various images or other electronic information, such as information for displaying a process procedure, a result of completion of the process, or other information. The display 21 may be a display screen or a touch display device with a touch function. The control panel 1 is generally provided with keys, knobs, and the like, and a user can operate the ultrasonic diagnostic apparatus through the control panel 1. The ultrasound device may also be provided with components such as wheels, handles, etc., which are not further described herein.

In the present embodiment, the control panel 1 and the display device 2 are mounted on the rotary linkage 3, and the rotary linkage 3 may be mounted on the main body 9.

The rotary linkage 3 is used for realizing synchronous rotation of more than two components. Referring to fig. 3-5, the rotary linkage 3 includes a first rotating component 31, a mounting bracket 33, a second rotating component 35, and a rotary motion transmission member 391. The first rotating member 31 and the second rotating member 35 may be disposed at two ends 331, 335 of the mounting bracket 33, respectively, or at other positions.

The mounting bracket 33 serves as a mounting structure for the first rotating assembly 31 and the second rotating assembly 35. The first rotating assembly 31 is used for mounting the control panel 1 or other components. The first rotating assembly 31 is mounted on the mounting bracket 33 and is capable of rotating on the mounting bracket 33 about a first axis of rotation. The second rotating assembly 35 is used to mount the display device 2 or other components. The second rotating assembly 35 is mounted on the mounting bracket 33 and is capable of rotating on the mounting bracket 33 about a second axis of rotation.

The rotating motion transmission member 391 is a transmission key between the first rotating component 31 and the second rotating component 35, and is connected to the first rotating component 31 and the second rotating component 35 respectively, and transmits the rotating motion of any one of the first rotating component 31 and the second rotating component 35 to the other, so that the first rotating component 31 and the second rotating component 35 can rotate synchronously.

Referring to fig. 1-4, in the present embodiment, the control panel 1 is mounted on the first rotating component 31 of the rotating linkage device 3. The display device 2 is mounted on a second rotating assembly 35. The control panel 1 and the display device 2 rotate synchronously with the display device 2 and the control panel 1 by the rotation linkage device 3.

In the ultrasonic equipment, because the respective rotation axes of the control panel 1 and the display device 2 rotate, the occupied space is small during rotation, and the problem that the whole rotation above the existing control panel occupies a large volume can be solved. And compared with a common rotating structure, the scheme has the advantages of better linkage, modular design of the whole structure, compact structure, convenience in maintenance and small occupied space.

Of course, the present embodiment shows that the display device 2 and the control panel 1 are synchronously rotated. In other embodiments, the display device 2 and the control panel 1 may be replaced with other components. Alternatively, the rotary linkage 3 may also comprise a third rotary assembly or more rotary assemblies, so that more components achieve a synchronous rotary motion.

Further, in one embodiment, the first axis of rotation is parallel to the second axis of rotation. The first rotating component 31 and the second rotating component 35 are arranged in parallel, so that the design of the rotating motion transmission member 391 is facilitated, the integral structure is simplified, and synchronous rotation can be realized without a complex transmission structure.

As an example, referring to fig. 4 and 5, in an embodiment, the first rotating assembly 31 has a first transmission member 3121, and when the first rotating assembly 31 moves, the first transmission member 3121 can rotate around the first rotation axis with the first rotation axis as a rotation center. The second rotating assembly 35 has a second transmission member 3521, and when the second rotating assembly 35 moves, the second transmission member 3521 can rotate around the second rotation axis with the second rotation axis as the rotation center line. The rotation transmission members 391 are connected to the first transmission member 3121 and the second transmission member 3521, respectively, and form a synchronous rotation mechanism. The rotation of the first transmission member 3121 is transmitted to the rotation transmission member 391, and drives the rotation transmission member 391 to move together, which may be linear motion or rotary motion. The rotating transmission member 391 drives the second transmission member 3521 to rotate while moving, so as to realize the synchronous rotation of the first transmission member 3121 and the second transmission member 3521.

With respect to the specific structure of the first rotating assembly 31 and the second rotating assembly 35 on the mounting bracket 33, referring to fig. 4, in one embodiment, the first rotating assembly 31 has a first rotating shaft 316. The second rotating assembly 35 has a second rotating shaft 356. The first shaft 316 and the second shaft 356 are rotatably mounted to the mounting bracket 33. The first transmission member 3121 rotates coaxially with the first rotation shaft 316 as a unit. The second transmission member 3521 and the second rotating shaft 356 coaxially rotate integrally. Specifically, the first rotating shaft 316 drives the first transmission member 3121 to rotate coaxially when rotating, and the second rotating shaft 356 drives the second transmission member 3521 to rotate coaxially when rotating.

The integral rotation can be realized by fixedly connecting the rotating shaft (including the first rotating shaft and/or the second rotating shaft) with the corresponding transmission piece (including the first transmission piece and/or the second transmission piece). Alternatively, the transmission of motion may be achieved using at least one of a friction transmission, a tooth mesh transmission and a structural limit transmission, which may be de-coupled by disengaging the transmission member from the shaft. Alternatively, the integral rotation may be accomplished by some clutch mechanism, such as a torque limiting clutch, an overload clutch or an overrunning clutch, which not only ensures the transmission of motion between the shaft and the transmission member, but also releases the linkage by setting a rated torque/speed, and once the torque/speed exceeds the rated torque/speed, the transmission member will not rotate with the shaft.

The first shaft 316 and the second shaft 356 may be rotatably mounted to the mounting bracket 33 by various means, such as bearings or other structures. With continued reference to FIG. 4, in one embodiment, the upper ends of the first and

second shafts

316, 356 have radially outwardly projecting catches. The lower ends of the first rotating shaft 316 and the second rotating shaft 356 are fixedly connected with rotating discs respectively, and the rotating discs are located at the lower ends of the first rotating shaft 316 and the second rotating shaft 356. The outer diameter of the rotary disk is larger than the outer diameter of the corresponding first rotating shaft 316 or second rotating shaft 356, that is, the outer diameter of the rotary disk installed on the first rotating shaft 316 is larger than the outer diameter of the first rotating shaft 316, and the outer diameter of the rotary disk installed on the second rotating shaft 356 is larger than the outer diameter of the second rotating shaft 356. The mounting bracket 33 has mounting holes, and the first and

second shafts

316 and 356 are mounted in the corresponding mounting holes and positioned on the mounting bracket 33 by respective catches and rotating discs. The rotating disc can be locked and fixed with the

rotating shafts

316 and 356 by means of screws and the like.

Further, in order to improve the smoothness of the rotation of the first rotating shaft 316 and the second rotating shaft 356. Referring to fig. 4, in one embodiment,

annular fixing plates

317 and 357 are respectively disposed between the respective locking platforms of the first rotating shaft 316 and the second rotating shaft 356 and the mounting bracket 33. The fixing

disks

317 and 357 are fixedly installed on the mounting bracket 33, and

bushings

318 and 358 are respectively disposed between the fixing

disks

317 and 357 and outer walls of the corresponding first and second

rotating shafts

316 and 356. Thus, the first shaft 316 and the second shaft 356 are preferably rotatable on the mounting bracket 33. Meanwhile,

bushings

319 and 359 may be disposed between the mounting hole of the mounting bracket 33 and the corresponding first rotating shaft 316 and second rotating shaft 356, so that the first rotating shaft 316 and the second rotating shaft 356 rotate more smoothly in the hole wall of the mounting hole.

Of course, the above-mentioned structure is only an example of the first rotating assembly 31 and the second rotating assembly 35 being rotatably mounted to the mounting bracket 33, and other structures, such as rotation by the cooperation of the rotating shaft and the bearing, may be adopted in other embodiments.

Further, in one embodiment, the first transmission member 3121 and the second transmission member 3521 may be located in the same plane, so that the rotation motions of the first transmission member 3121 and the second transmission member 3521 are also in the same plane, and thus may be more easily transmitted to each other. Of course, in some embodiments, the first transmission member 3121 and the second transmission member 3521 may be located on different planes, which requires a more complicated transmission structure of the rotation transmission member 391.

In one embodiment, the synchronous rotation mechanism formed by the first transmission member 3121, the second transmission member 3521 and the transmission member 391 adopts a chain and sprocket transmission structure to transmit the rotation motion.

Referring to fig. 4 and 5, the first transmission member 3121 and the second transmission member 3521 are sprockets, and the rotating transmission member 391 is a chain. The sprocket 3121 is linked with the sprocket 3521 via a chain 391, and the degree of tightness of the chain is adjusted by the sprocket 395.

As shown in fig. 5, when the control panel 1 rotates, for example, clockwise, the first rotating shaft 316 is driven to rotate clockwise, and the sprocket 3121 is driven to rotate clockwise synchronously. Through the linkage transmission of chain 391, sprocket 3521 also can rotate clockwise, drives second pivot 356 clockwise in step, drives display device 2 clockwise promptly. The effect of the rotary linkage motion of the control panel 1 and the display device 2 is realized.

In addition, in an embodiment, the synchronous rotation mechanism formed by the first transmission member, the second transmission member and the rotation transmission member can also be implemented by a synchronous belt transmission structure, which is implemented in a manner similar to the sprocket chain implementation principle and will not be described in detail here.

In addition, the synchronous rotating mechanism formed by the first transmission piece, the second transmission piece and the rotary motion transmission piece can be realized by adopting a pulley and rope transmission structure. As shown in fig. 6-8, in one embodiment, the first and second transmission members are

pulleys

3122, 3522 and the rotational movement transmission member is a cable 392. The first rotation shaft 316 and the pulley 3122 are rotatably movable with respect to the fixed disk 317. The second shaft 356 and the pulley 3522 are rotatably movable with respect to the fixed disk 357. Pulley 3122 is in winding linkage with pulley 3522 via a cable 392, and another pulley or take-up clamp 3962 is used for assembly adjustment of the tightness of the cable.

In addition, in an embodiment, the synchronous rotating mechanism formed by the first transmission member, the second transmission member and the rotating motion transmission member can also be realized by adopting endless belt transmission, and the realization mode is similar to the rope transmission realization principle, and is not described in detail here.

In one embodiment, the synchronous rotating mechanism formed by the first transmission member, the second transmission member and the rotating motion transmission member can be realized by a gear set transmission structure. As shown in fig. 9, the first and second transmission members are

gears

3125, 3525, and the rotary motion transmission member is also gear 3985. The first rotation shaft 316 and the gear 3125 are rotatably movable with respect to the fixed disk 317. The second shaft 356 and the gear 3525 are rotatably movable with respect to the fixed disk 357. Gear 3125 and gear 3525 are engaged by adding several gears 3985 in the middle to form a gear set.

In one embodiment, the synchronous rotating mechanism formed by the first transmission member, the second transmission member and the rotating motion transmission member can be realized by a gear-rack transmission structure. As shown in fig. 10, the first and second transmission members are

gears

3126, 3526, and the rotational motion transmission member is a rack 3986. The first rotation shaft 316 and the gear 3126 are rotatably movable with respect to the fixed disk 317. The second shaft 356 and the gear 3526 are rotatably movable with respect to the fixed disk 357. Gear 3126 is coupled in rotational movement with gear 3526 by engagement with rack 3986.

Of course, the above are only examples of several synchronous rotating mechanisms, and in other embodiments, there are many possible implementations: such as a link combination, a cam and link combination, a link and slide combination, a cam and slide combination, etc., which are not exhaustive, and variants similar to or based on the above description are also applicable to the synchronous rotating mechanism shown in the present application.

On the other hand, in a general ultrasonic apparatus, the display device 2 may be positioned higher than the control panel 1 to satisfy the user's visual requirements and input habits. Therefore, in one embodiment, the mounting position of the second rotating assembly 35 for mounting the display device 2 is higher than the mounting position of the first rotating assembly 31 for mounting the control panel 1. Thereby, the position of the display device 2 can be made higher than the position of the control panel 1.

In order to realize the height difference between the second rotating assembly 35 and the first rotating assembly 31, the lengths of the first rotating shaft 316 and the second rotating shaft 356 may be set to be different, or the heights of the two shafts extending upwards may have a set height difference, or the installation position of the second rotating assembly 35 may be raised by other structures.

Referring to fig. 11-13, in one embodiment, the second rotating assembly 35 further includes a third rotating shaft 366 and a transmission shaft 368. The third shaft 366 is located above the second shaft 356. The transmission shaft 368 is coaxially connected to both the second rotating shaft 356 and the third rotating shaft 366, so as to transmit the rotational motion of the second rotating shaft 356 to the third rotating shaft 366. The third rotating shaft 366 is used for installing the display device 2, and the installation position of the third rotating shaft 366 for installing the display device 2 is higher than the installation position of the first rotating assembly 31 for installing the control panel 1, and meanwhile, the rotating motion of the first rotating assembly 31 can be stably transmitted to the third rotating shaft 366, or the rotating motion of the third rotating shaft 366 can be stably transmitted to the first rotating assembly 31.

Further, with continued reference to fig. 11-13, in one embodiment, the mounting bracket 33 has a second bracket 337 protruding upward, and the third shaft 366 is rotatably mounted on the second bracket 337. Thus, the second rotating shaft 356 and the third rotating shaft 366 are stably supported, so that the rotating motion of the second rotating shaft 356 and the third rotating shaft 366 can be more stable.

The mounting structure of the third shaft 366 on the second bracket 337 can refer to the first shaft 316 and the second shaft 356, but can also take other forms, such as being implemented by bearings. Referring to fig. 11 and 12, in one embodiment, the upper end of the third shaft 366 has a third locking platform (the locking platforms of the first shaft 316 and the second shaft 356 can be respectively referred to as a first locking platform and a second locking platform). A third rotating disk 3621 is fixedly connected to the lower end of the third rotating shaft 366 (the rotating disks to which the first rotating shaft 316 and the second rotating shaft 356 are connected can be regarded as a first rotating disk and a second rotating disk, respectively). The outer diameter of third rotating disk 3621 is larger than the outer diameter of third rotating shaft 366. The second bracket 337 has a mounting hole, and the third rotating shaft 366 is positioned on the second bracket 337 by the third chuck and the third rotating disk 3621 in the corresponding mounting hole.

Similarly, an annular third fixed disk 367 may be disposed between the third clamping platform and the second bracket 337, the third fixed disk 367 is fixedly mounted on the second bracket 337, and a bushing is disposed between the third fixed disk 367 and the outer wall of the third rotating shaft 366 to improve the smoothness of the rotation of the third rotating shaft 366.

Referring to fig. 12, after the rotary linkage device 3 with the raised structure is adopted, the display device 2 can be located at a higher position to meet the visual requirement of the user. The control panel 1 is arranged at a lower position, so that the manual operation requirement of a user is facilitated, and the ergonomics is better met.

Further, in one embodiment, at least one of the first rotating assembly and the second rotating assembly further comprises a clutch mechanism. The clutch mechanism is used for enabling the first transmission piece and/or the second transmission piece to be linked with and disconnected from the corresponding first rotating shaft and/or the corresponding second rotating shaft. The clutch mechanism may be used only to control the transmission of motion between the drive member and the shaft in either the first or second rotary assemblies. Alternatively, the first rotating unit or the second rotating unit may be simultaneously controlled by providing a clutch mechanism in each of the first rotating unit and the second rotating unit.

The clutch mechanism can be a mechanism which can promote the transmission member and the rotating shaft to be separated and connected, so that the transmission member and the rotating shaft can be linked and decoupled. As described above, the transmission member and the rotating shaft may be at least one of a friction transmission, a tooth engagement transmission and a structural limit transmission to transmit the motion, which may facilitate the coupling and decoupling of the transmission member and the rotating shaft by the clutch mechanism. Alternatively, the clutch mechanism may be a type of device that is capable of releasing the linkage by setting a nominal torque/speed, such as a torque limiting clutch, an overload clutch, or an overrunning clutch. This way not only can ensure the transmission of motion between the rotating shaft and the transmission member, but also once the torque/rotational speed exceeds the rated torque/rotational speed, the transmission member will not rotate with the rotating shaft any more.

Referring to fig. 14 and 15, the first rotating assembly 31 is illustrated as an example, and the second rotating assembly can be implemented as well. The clutch mechanism comprises a manual shifting lever 81 and a trigger 85, and the manual shifting lever 81 drives the trigger 85 to move. The manual lever 81 is easily controlled by an operator to manipulate the position of the manual lever 81 by the user, thereby driving the trigger 85 to move. The trigger 85 may take the form of a drive shaft as shown or other form of structure. The triggering member 85 is engaged with the first transmission member 3121 and/or the second transmission member (not shown in the drawings) for driving the first transmission member 3121 and/or the second transmission member to link and release the link with the corresponding first rotating shaft 316 and/or the second rotating shaft (not shown in the drawings). For example, when the manual lever 81 is moved to the position shown in fig. 14, the first rotating shaft 316 and the first transmission member 3121 are connected to rotate integrally. When the manual lever 81 is moved to the position shown in fig. 15, the triggering member 85 pushes the first transmission member 3121 to move away from the first rotation shaft 316, and the first rotation shaft 316 and the first transmission member 3121 are separated, thereby releasing the integral rotation.

Further, with continued reference to fig. 14 and 15, in one embodiment, the clutch mechanism further includes a return spring (not shown). The manual lever 81 is pivoted about a fulcrum (pivot shaft 83) to form a lever structure. The shorter end of the arm of force of the manual shift lever 81 is the driving end, with the fulcrum of the manual shift lever 81 as the boundary. The trigger 85 is movably disposed in the vertical direction and located on the motion track of the downward rotation of the driving end, so that the driving end can drive the trigger 85 to move downward in the rotation process, as shown in fig. 15. The first transmission member 3121 and/or the second transmission member are located below the corresponding triggering member 85 and are separated from the corresponding first rotating shaft 316 and/or the second rotating shaft under the driving of the triggering member 85, so as to realize linkage contact.

The return elastic element is used for returning the triggering element 85 and the corresponding first transmission element 3121 and/or second transmission element upward. The return elastic member may be a spring, which may act directly on the first transmission member 3121 and/or the second transmission member, or may act on a member connected to the first transmission member 3121 or the second transmission member. When the manual lever 81 is shifted to the position shown in fig. 14, the return elastic member will urge the first transmission member 3121 and/or the second transmission member to return to be linked with the corresponding first rotating shaft 316 and/or the second rotating shaft.

Of course, in other embodiments, the triggering member 85 can be directly or indirectly linked with the manual lever 81, so as to drive the triggering member 85 to move up and down.

In other embodiments, the triggering member 85 and the transmission member (the first transmission member 3121 and/or the second transmission member) may be movably connected, so that the transmission member is driven by the triggering member 85 to be separated from and close to the rotating shaft, and the return elastic member may be omitted or provided on the triggering member 85.

In addition to a manually controlled clutch mechanism, in some embodiments the clutch mechanism also includes a drive member capable of outputting a reciprocating motion, such as an electric motor, a pneumatic cylinder, a hydraulic cylinder, an electromagnet, or the like. The output end of the driving member is matched with the first transmission member 3121 and/or the second transmission member, so as to drive the first transmission member 3121 and/or the second transmission member to be linked with and decoupled from the corresponding first rotating shaft 316 and/or second rotating shaft. The driving piece can control the clutch mechanism according to the instruction input by the user, and the operation is more convenient.

In some embodiments, one of a torque limiting clutch, an overload clutch, and an overrunning clutch may be employed as the clutch mechanism. At this time, the first rotating shaft 316 and/or the second rotating shaft are connected with the first transmission member 3121 and/or the second transmission member through corresponding clutch mechanisms. As soon as the torque/rotational speed exceeds the set torque/rotational speed, the transmission element will no longer rotate with the rotating shaft.

The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. Variations of the above-described embodiments may be made by those skilled in the art, consistent with the principles of the invention.
