Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of medical equipment, and in particular to a medical input device and an ultrasonic imaging device. Background Art

[0002] Medical devices require an operation panel equipped with an input module to receive user input control information. For example, in an ultrasound imaging device, the direction, speed, or trajectory of the user's operation on the input module is detected to generate corresponding control information, and then scanning and imaging are performed based on the control information.

[0003] It should be noted that the above introduction to the technical background is only intended to provide a clear and complete description of the technical solution of the present application and to facilitate understanding by those skilled in the art. Summary of the Invention

[0004] The inventors discovered that during the use of medical devices, there is a need to remove, install, or replace input modules. For example, if the input module malfunctions, requires cleaning or maintenance, or is not the module the user intended, the need to remove, install, or replace the input module may arise.

[0005] The input module is usually fixed to the operation panel in an irremovable manner. Therefore, if you want to remove, install or replace the input module, you need to remove, install or replace the entire input device (for example, the operation panel and the input module, etc.), which makes the operation complicated, time-consuming and labor-intensive, and cannot guarantee the user experience. Some other existing technologies provide detachable input modules. As a whole, it is detachably connected to the operation panel. Such a structure needs to consider the mechanical connection between the input module and the operation panel on the one hand, and the electrical connection between the two on the other hand. How to strike a balance between the reliability and simplicity of the connection remains a challenge.

[0006] To address at least one of the above technical issues, embodiments of the present application provide a medical input device and an ultrasonic imaging device, wherein it is expected that the input module can be easily disassembled, installed, or replaced.

[0007] According to one aspect of an embodiment of the present application, a medical input device is provided, comprising: an input module comprising a main body, a first fixing portion and a first electrical connection portion; and an operating panel comprising a accommodating portion for accommodating the main body, a second fixing portion and a second electrical connection portion, wherein the input module rotates relative to the operating panel along a first rotation trajectory and is detachably connected to the operating panel, and when the input module is located at a first position on the first rotation trajectory, the first fixing portion is connected to the second fixing portion, and when the input module is located at a second position on the first rotation trajectory, the first electrical connection portion is connected to the second electrical connection portion.

[0008] According to another aspect of an embodiment of the present application, an ultrasonic imaging device is provided, comprising the medical input device as described above.

[0009] One of the beneficial effects of the embodiments of the present application is that the input module can be connected to the operation panel in a detachable manner through rotational movement. By moving the input module along the rotational trajectory, when the input module reaches the corresponding position on the rotational trajectory, not only can the mechanical connection between the input module and the operation panel be achieved, but also the electrical connection between the input module and the operation panel can be achieved. The operation is simple and reliable, and the user experience is improved.

[0036] The following is a detailed description of the embodiments of the present application.

[0037] An embodiment of the present application provides a medical input device.

[0038] Figure 1 FIG is a schematic diagram of a medical input device according to an embodiment of the present application. Figure 1 As shown, the medical input device 100 includes an input module 1 and an operation panel 2 .

[0039] Figure 2 Schematic diagram of the input module of the embodiment of the present application. Figure 2 As shown, the input module 1 includes a main body 11 , a first fixing portion 12 and a first electrical connection portion 13 .

[0040] Figure 3 Schematic diagram of the operation panel of the embodiment of the present application. Figure 3 As shown, the operation panel 2 includes a receiving portion 21 for receiving the main body 11 , a second fixing portion 22 and a second electrical connection portion 23 .

[0041] The input module 1 rotates relative to the operation panel 2 along a first rotation trajectory and is connected to the operation panel 2 in a detachable manner. When the input module 1 is located at a first position on the first rotation trajectory, the first fixing portion 12 is connected to the second fixing portion 22. When the input module 1 is located at a second position on the first rotation trajectory, the first electrical connection portion 13 is connected to the second electrical connection portion 23.

[0042] According to the above embodiment, in the medical input device 100, the input module 1 and the operating panel 2 are detachably connected, making it convenient for the user to install, remove, or replace the input module 1 as needed. Furthermore, the input module 1 can be detachably connected to the operating panel 2 through rotational motion. By moving the input module 1 along a rotational trajectory, when the input module 1 reaches a corresponding position on the rotational trajectory, not only is the mechanical connection between the input module 1 and the operating panel 2 achieved, but also the electrical connection is achieved, making operation simple and reliable.

[0043] In some embodiments, Figures 1 to 3The medical input device is illustrated using a trackball module as an example. The present application is not limited thereto; the input module 1 may also be a touchpad module; or the input module 1 may include a trackball module and a touchpad module, the trackball module and the touchpad module being interchangeably connected to the operation panel 2.

[0044] The input module is described below by taking the trackball module and the touchpad module as examples.

[0045] Figure 4 FIG. 1 is a schematic diagram of a trackball module according to an embodiment of the present application. Figure 4 As shown, the main body 1-21 of the trackball module 1-2 includes a base assembly 1-211 and a trackball assembly 1-212. The base assembly 1-211 and the trackball assembly 1-212 are assembled in a detachable manner. By assembling the base assembly 1-211 and the trackball assembly 1-212 in a detachable manner, the base assembly 1-211 and the trackball assembly 1-212 can be easily cleaned or replaced.

[0046] In some embodiments, as Figure 4 As shown, the first electrical connection portion 1-23 can be provided on the base assembly 1-211. The present application is not limited thereto, and the first electrical connection portion 1-23 can also be provided on the trackball assembly 1-212.

[0047] In some embodiments, the first fixing portion 1-22 may be provided on the base assembly 1-211 and the trackball assembly 1-212. The present application is not limited thereto, and the first fixing portion 1-22 may also be provided on one of the base assembly 1-211 and the trackball assembly 1-212.

[0048] Figure 5 FIG is a schematic diagram of a trackball assembly and a first fixing portion according to an embodiment of the present application. Figure 4 and Figure 5 As shown, the trackball assembly 1-212 may include a ball 1-2121 and a cover plate 1-2122. The cover plate 1-2122 includes a first surface A ( Figure 4 ) and a second surface B ( Figure 5 ), the cover plate 1-2122 has an opening in the center thereof that passes through the first surface A and the second surface B, and a claw portion 1-2123 is provided on the second surface B. A portion of the ball 1-2121 is exposed from the opening and is held by the claw portion 1-2123 in a rotatable state.

[0049] In some embodiments, the number of the claws 1-2123 can be one or more.

[0050] For example, Figure 5As shown, there may be multiple claws 1-2123. One end of the claw 1-2123 is connected to the second surface (either directly or by other components), and the claw 1-2123 includes a portion extending axially and radially inward relative to the one end, thereby enabling the claw 1-2123 to support the ball 1-2121 in the axial direction.

[0051] For another example, there may be one claw portion 1-2123. One end of the claw portion is connected to the second surface (either directly or by other components), and the other end is provided with a supporting portion. The supporting portion supports the ball 1-2121 in the axial direction. The supporting portion may be of various structures. For example, the supporting portion may be a ring with an opening. By providing the opening, the ball 1-2121 and the cover plate 1-2122 can be easily separated or assembled, thereby facilitating cleaning or replacement of the ball 1-2121 and the cover plate 1-2122.

[0052] In some embodiments, the base assembly 1-211 and the trackball assembly 1-212 may be separably assembled in various ways.

[0053] For example, the base assembly 1-211 and the trackball assembly 1-212 are respectively connected to the operation panel 2 in a detachable manner. Figure 4 As shown, the first fixing portion 1-22 includes a fifth fixing portion 1-221 arranged on the base assembly 1-211 and a sixth fixing portion 1-222 arranged on the trackball assembly 1-212.

[0054] Figure 6 : is a schematic diagram of the second fixing portion of the embodiment of the present application. Figure 6 As shown, corresponding to the fifth fixing portion 1 - 221 and the sixth fixing portion 1 - 222 of the first fixing portion 1 - 22 , the second fixing portion 22 may include a seventh fixing portion 221 and an eighth fixing portion 222 disposed in the accommodating portion 21 .

[0055] By connecting the fifth fixing portion 1 - 221 to the seventh fixing portion 221 and the sixth fixing portion 1 - 222 to the eighth fixing portion 222 , the trackball assembly 1 - 212 and the base assembly 1 - 211 can be assembled together, and the trackball module 1 - 2 can be mounted to the operation panel 2 .

[0056] The present application is not limited thereto, and the base assembly 1-211 and the trackball assembly 1-212 may also be separably assembled in other ways. For example, the base assembly 1-211 may include a ninth fixing portion, and the trackball assembly 1-212 may include a tenth fixing portion, wherein the ninth fixing portion and the tenth fixing portion are detachably connected, thereby enabling the base assembly 1-211 and the trackball assembly 1-212 to be separably assembled. In this case, the first fixing portion 1-22 may be provided on the base assembly 1-211, or on the trackball assembly 1-212, or on both the base assembly 1-211 and the trackball assembly 1-212.

[0057] In some embodiments, when the trackball module 1-2 is mounted on the operating panel 2, the ball 1-2121 in the trackball assembly 1-212 may abut against components of the base assembly 1-211. By detecting the trajectory and / or velocity of the ball 1-2121, control information is generated and transmitted via the first electrical connection 1-23 to the second electrical connection 23 of the operating panel 2, thereby controlling other components of the ultrasound imaging device to perform related operations.

[0058] Figure 7 FIG is a schematic diagram of a touch panel module according to an embodiment of the present application. Figure 7 As shown, in the touch panel module 1-1, the first fixing portion 1-12 and the first electrical connection portion 1-13 are provided on the main body portion 1-11.

[0059] For example, the main body 1-11 includes a cover plate 1-111 and a touch panel 1-112, and the touch panel 1-112 is arranged on the inner side of the cover plate 1-111. The cover plate 1-111 includes a first surface C and a second surface D, wherein the first fixing portion 1-12 and the first electrical connection portion 1-13 are arranged on the second surface D side.

[0060] The first electrical connection portion 1-13 is electrically connected to the touch panel 1-112. By detecting the trajectory and / or speed of a user's finger or the like on the touch panel 1-112, control information is generated and transmitted to the second electrical connection portion 23 of the operation panel 2 via the first electrical connection portion 1-13, thereby controlling other components of the ultrasonic imaging device to perform related operations.

[0061] In some embodiments, the first fixing portion and the second fixing portion may be connected in various ways, such as a snap connection, a threaded connection, etc.

[0062] The following describes the connection method between the first fixing portion 1-12 of the touchpad module 1-1 and the second fixing portion 22 of the operation panel 2 as an example. It should be understood that the following description of the connection method between the first fixing portion and the second fixing portion is also applicable to the first fixing portion 1-22 (e.g., the fifth fixing portion 1-221 and the sixth fixing portion 1-222) of the trackball module 1-2 and the second fixing portion 22 (the seventh fixing portion 221 and the eighth fixing portion 222) of the operation panel 2.

[0063] Take the snap connection as an example, Figure 7 As shown, the first fixing portion 1-12 may have a sheet portion 1-121 extending axially from the second surface D, and a groove 1-122 extending axially is provided on one circumferential side of the sheet portion 1-121.

[0064] like Figure 6 As shown, the second fixing portion 22 can be a protrusion protruding radially inward from the side wall of the accommodating portion 21. By engaging the groove 1-122 with the protrusion, the first fixing portion 1-12 and the second fixing portion 22 can be connected, and the convenience of installing or removing the input device can be improved.

[0065] The present application is not limited thereto, and the first fixing portion 1-12 may also have other structures. For example, in the first fixing portion 1-12, a protrusion is provided on one circumferential side of the sheet portion 1-121; the second fixing portion may have a groove that is recessed radially outward from the side wall of the receiving portion 21, and the protrusion engages with the groove.

[0066] The first fixing portion 1 - 12 can be made of a flexible material to facilitate engagement.

[0067] In some embodiments, the groove 1-122 and the second surface D may not be in contact. Figure 7 As shown, the groove 1-122 is provided on an extension portion 1-123 extending circumferentially from the sheet portion 1-121. A gap S is provided between the groove 1-122 and the second surface D. This not only increases the elasticity of the first fixing portion 1-12, but also allows the touchpad module 1-1 to be guided via the gap S. Furthermore, the gap S between the groove and the second surface D allows for engagement. This further improves engagement reliability and facilitates installation and removal of the trackball device.

[0068] Figure 8 Schematic diagram of the engagement state of the first fixing portion and the second fixing portion of the embodiment of the present application. Figure 6 and Figure 8 As shown, the operation panel 2 may further include a limiting portion 24 . The limiting portion 24 may be located above the second fixing portion 22 .

[0069] like Figure 8 As shown, when the first fixing portion 1-12 is engaged with the second fixing portion 22, the limiting portion 24 is accommodated in the gap S. The first fixing portion 1-12 can abut against the limiting portion 24 in the vertical direction. Thus, the input module 1 can be limited in the vertical direction.

[0070] In some embodiments, as Figure 6 and Figure 8 As shown, the operation panel 2 may further include a step portion 25 extending along the circumferential direction. The step portion 25 may be located at a lower side of the second fixing portion.

[0071] like Figure 8 As shown, when the first fixing portion 1-12 is engaged with the second fixing portion 22, the step portion 25 is located below the first fixing portion 1-12. The first fixing portion 1-12 can abut against the step portion 25 in the vertical direction. Thus, the input module 1 can be limited in the vertical direction.

[0072] In some embodiments, in the trackball module 1-2, the fifth fixing portion 1-221 and the sixth fixing portion 1-222 of the first fixing portion 1-22 may have the same or similar structures as the first fixing portion 1-12 of the touchpad module 1-1. Thus, a single operation panel 2 can accommodate both the trackball module 1-2 and the touchpad module 1-1.

[0073] In some embodiments, as Figure 6 As shown, the second fixing portion 22 of the operation panel 2 includes a seventh fixing portion 221 and an eighth fixing portion 222, which are respectively connected to the fifth fixing portion 1-221 and the sixth fixing portion 1-222 of the first fixing portion 1-22 of the trackball module 1-2. When the touchpad module 1-1 is installed in the operation panel 2, the first fixing portion 1-12 of the touchpad module 1-1 can be connected to the seventh fixing portion 221. The present application is not limited to this, and the first fixing portion 1-12 of the touchpad module 1-1 can also be connected to the eighth fixing portion 222.

[0074] In some embodiments, the first fixing portion 12 may include multiple members, and accordingly, the second fixing portion 22 may also include multiple members. The multiple first fixing portions 12 and the multiple second fixing portions 22 may be unevenly arranged along the circumference of the main body. This facilitates the user's identification of the orientation of the input module 1 and facilitates installation of the input module 1 in the receiving portion 21 of the operation panel 2 in the correct orientation.

[0075] Figure 9 FIG. 1 is a schematic diagram of the cover of the trackball module according to an embodiment of the present application. Figure 9As shown, three first fixing portions 1-22 are provided on the cover plate 1-2122, wherein the three first fixing portions 1-22 are spaced at different intervals in the circumferential direction. The present application is not limited thereto, and the first fixing portions and the second fixing portions may also be evenly provided along the circumference of the main body.

[0076] In some embodiments, the input module 1 may also be provided with a mark for marking the orientation of the input module 1. Thus, the user can confirm the orientation of the input module 1 according to the mark. Figure 4 As shown, in the trackball module 1-2, marks E and F may be provided in the base assembly 1-211 and the trackball assembly 1-212, respectively.

[0077] In some embodiments, the input module 1 may perform a rotational descending or rotational ascending motion along at least a portion of the first rotation trajectory.

[0078] For example, the process of the input module 1 moving along the starting point of the first rotation trajectory to the end point of the first rotation trajectory is the process of installing the input module 1 to the operation panel 2; the process of the input module 1 moving along the end point of the first rotation trajectory to the starting point of the first rotation trajectory is the process of removing the input module 1 from the operation panel 2.

[0079] When the input module 1 is located at the starting point of the first rotation track, the upper end surface of the input module 1 can be located at a higher position than the upper end surface of the operation panel 2. This makes it easier for the user to remove the input module 1 from the operation panel 2.

[0080] When the input module 1 is located at the end point of the first rotation track, the upper end surface of the input module 1 may be at the same height as the upper end surface of the operation panel 2. This makes it easier for the user to operate the input module 1.

[0081] In some embodiments, the input module 1 may be provided with a force-applying portion, so that the user can apply a rotational force to the input module 1 through the force-applying portion, thereby facilitating the disassembly and installation operations of the input module 1. Figure 4 As shown, in the trackball module 1-2, a force applying portion G may be provided in the trackball assembly 1-212; Figure 7 As shown, a force applying portion H may be provided in the touch panel module 1 - 1 .

[0082] In some embodiments, the input module 1 can be rotated along the first rotation trajectory in various ways. Figure 6 As shown, the operation panel 2 may be provided with a first step portion 26. The first step portion 26 protrudes radially inward from the side wall of the receiving portion 21 of the operation panel 2. The first step portion 26 includes at least an inclined portion 261 extending in the circumferential direction and the axial direction.

[0083] At least a portion of the lower surface of the first fixing portion 11 of the input module 1 abuts against the upper surface of the first step portion 26. In this state, the input module 1 moves along the first step portion 26 and can rotate downward or upward when passing through the inclined portion 261.

[0084] In some embodiments, one end of the first step portion 26 may be connected to the aforementioned step portion 25 and have the same height as each other, thereby enabling the input module 1 to reliably rotate to a position where it is connected to the second fixing portion 22 .

[0085] In some embodiments, the other end of the first step portion 26 (corresponding to the starting point of the first rotation trajectory) can be horizontal, so that the input module 1 can be stably placed on the other end of the first step portion 26, avoiding unexpected movement of the input module 1 and facilitating user operation.

[0086] The present application is not limited thereto, and the input module 1 may be rotated along the first rotation track in other ways, such as by providing a groove-type guide rail on the side wall of the receiving portion 21 of the operation panel 2 .

[0087] In some embodiments, the first fixing portion 12 of the input module 1 and the second fixing portion 22 of the operation panel 2 can be connected when the input module 1 is in a first position of the first rotation track; and the first electrical connection portion 13 of the input module 1 and the second electrical connection portion 23 of the operation panel 2 can be connected when the input module 1 is in a second position of the first rotation track. The first position and the second position can be various positions on the first rotation track.

[0088] For example, the first position and the second position can be the endpoints of the first rotation trajectory. In other words, when the input module 1 rotates along the first rotation trajectory to the endpoint, not only is the mechanical connection between the first fixing portion 12 and the second fixing portion 22 established, but the electrical connection between the first electrical connection portion 13 and the second electrical connection portion 23 is also established. Thus, the user only needs to rotate the input module 1 to the endpoint of the first rotation trajectory to achieve the mechanical and electrical connection between the input module 1 and the operation panel 2, without having to plug or unplug the first electrical connection portion 13 and the second electrical connection portion 23, making operation simple and quick.

[0089] In some embodiments, the first electrical connection portion 13 and the second electrical connection portion 23 can be connected in a plug-free manner. For example, when the input module 1 is at the end of the first rotation track, the first electrical connection portion 13 and the second electrical connection portion 23 abut against each other.

[0090] like Figure 2 and Figure 3 As shown, the first electrical connection portion 13 and the second electrical connection portion 23 may be spring pin interfaces (eg, pogo-pin interfaces, etc.), thereby improving the reliability of the electrical connection.

[0091] In some embodiments, the abutting direction of the first electrical connection portion 13 and the second electrical connection portion 23 may be the same as the connecting direction of the first fixing portion 12 and the second fixing portion 22. Figure 8 As shown, the first fixing portion 1 - 12 and the second fixing portion 22 are engaged in the horizontal direction, and the first electrical connection portion 13 and the second electrical connection portion 23 are also in contact with each other in the horizontal direction.

[0092] In some embodiments, the first electrical connection portion 13 can be disposed at a position staggered from the first fixing portion 12 in the circumferential direction, thereby avoiding interference between the first electrical connection portion 13 and the second fixing portion 22. Similarly, the second electrical connection portion 23 can be disposed at a position staggered from the second fixing portion 22 in the circumferential direction.

[0093] The following describes the replacement process for the input module 1, taking the example of replacing a touchpad module with a trackball module, with the first and second electrical connectors connected in a plug-and-play fashion. It should be understood that the following description also applies to replacing a trackball module with a touchpad module, simply by following the steps in reverse order.

[0094] Step 1: Rotate the touchpad module 1-1 along a first rotational trajectory-1, from the end point of the first rotational trajectory-1 to the starting point of the first rotational trajectory-1. At this point, the first fixing portion 1-12 of the touchpad module 1-1 is mechanically disconnected from the second fixing portion 22 of the operating panel 2; the first electrical connection portion 1-13 of the touchpad module 1-1 is electrically disconnected from the second electrical connection portion 23 of the operating panel 2; and the upper end surface of the touchpad module 1-1 is positioned higher than the upper end surface of the operating panel 2, making it easier for the user to remove the touchpad module 1-1 from the receiving portion 21 of the operating panel 2.

[0095] Step 2: Rotate the base assembly 1-211 of the trackball module 1-2 along the first rotational trajectory-1, from the starting point of the first rotational trajectory-1 to the end point of the first rotational trajectory-1. At this point, the fifth fixing portion 1-221 of the base assembly 1-211 is mechanically connected to the seventh fixing portion 221 of the operation panel 2; and the first electrical connection portion 1-23 of the trackball module 1-2 is electrically connected to the second electrical connection portion 23 of the operation panel 2.

[0096] Step 3: Rotate the trackball assembly 1-212 of the trackball module 1-2 along the first rotation trajectory-2, from the starting point of the first rotation trajectory-2 to the end point of the first rotation trajectory-2 (wherein the first rotation trajectory includes the first rotation trajectory-1 and the first rotation trajectory-2. The first rotation trajectory-2 is parallel to the first rotation trajectory-1 and is located above the first rotation trajectory-1). At this point, the sixth fixing portion 1-222 of the trackball assembly 1-212 is mechanically connected to the eighth fixing portion 222 of the operation panel 2. Thus, the operation of replacing the touchpad module with the trackball module 1-2 is completed.

[0097] In some embodiments, the first position and the second position may also be other positions on the first rotation trajectory. For example, the first position may be the end point of the first rotation trajectory, and the second position may be the starting point of the first rotation trajectory. In other words, when the input module 1 is at the starting point of the first rotation trajectory, the first electrical connection portion 13 is connected to the second electrical connection portion 23, and while maintaining the connection between the first electrical connection portion 13 and the second electrical connection portion 23, the input module 1 rotates along the first rotation trajectory. When the input module 1 rotates to the end point of the first rotation trajectory, the first fixing portion 12 is connected to the second fixing portion 22. Thus, the user only needs to place the input module 1 at the starting point of the first rotation trajectory and rotate it to the end point of the first rotation trajectory to achieve the electrical and mechanical connection between the input module 1 and the operation panel 2, which not only facilitates operation but also ensures the reliability of the electrical connection.

[0098] In some embodiments, the second electrical connection portion 23 can be rotated to the second position along with the input module 1 in various ways.

[0099] Figure 10 is another schematic diagram of the operation panel of the embodiment of the present application. Figure 10 As shown, the operation panel 2 may further include a holding portion 27. The holding portion 27 is fixedly connected to the second electrical connection portion 23 and rotates along a second rotation track parallel to the first rotation track.

[0100] For example, when the first electrical connection portion 13 is connected to the second electrical connection portion 23 , the holding portion 27 rotates synchronously with the input module 1 .

[0101] In some embodiments, the first electrical connection portion 13 and the second electrical connection portion 23 can be connected in a plug-in manner, thereby enabling the input module 1 to reliably drive the holding portion 27 to rotate synchronously.

[0102] Figure 11 FIG. 1 is another schematic diagram of the trackball module according to an embodiment of the present application. Figure 11 As shown, the first electrical connection portion 1-23 can be provided on the base assembly 1-211. Figure 10 and Figure 11As shown, the first electrical connection portion 1 - 23 and the second electrical connection portion 23 can be connected by plugging and unplugging in the axial direction.

[0103] Figure 12 FIG is another schematic diagram of the touch panel module according to an embodiment of the present application. Figure 12 As shown, the first electrical connection portion 1-13 can be provided on the second surface D side of the touch panel module 1-1. Figure 10 and Figure 12 As shown, the first electrical connection portion 1 - 13 and the second electrical connection portion 23 can be connected by plugging and unplugging in the axial direction.

[0104] In some embodiments, when the input module 1 is located at the starting point of the first rotational trajectory and the retaining portion 27 is located at the first end of the second rotational trajectory, the first electrical connection portion 13 and the second electrical connection portion 23 can overlap with each other (for example, overlap in the axial direction). In other words, when the input module 1 is placed at the starting point of the first rotational trajectory and the retaining portion 27 is placed at the first end of the second rotational trajectory, the first electrical connection portion 13 and the second electrical connection portion 23 can be connected. For example, the second electrical connection portion 23 can be inserted into the first electrical connection portion 13, or the first electrical connection portion 13 can be inserted into the second electrical connection portion 23.

[0105] In some embodiments, the first electrical connection portion 13 and the second electrical connection portion 23 may be plug-in interfaces. For example, the two may be connected in a pluggable manner, thereby improving the reliability and service life of the electrical connection.

[0106] In some embodiments, the holding portion 27 may be rotated along the second rotation trajectory in various ways. Figure 13 is another schematic diagram of the operation panel of the embodiment of the present application. Figure 10 and Figure 13 As shown, the operation panel 2 may further include a support portion 28. The support portion 28 includes a first guide 281. The holding portion 27 may include a second guide. When the first guide 281 is engaged with the second guide, the holding portion 27 rotates along the second rotation trajectory.

[0107] In some embodiments, as Figure 13 As shown, the support portion 28 can be arranged at the lower side of the accommodation portion 21. The present application is not limited thereto, and the support portion 28 can also be arranged inside the accommodation portion 21, etc.

[0108] In some embodiments, the second guide of the holding portion 27 and the first guide of the supporting portion 28 may be in various forms. Figure 14 is a schematic diagram of the holding portion and the supporting portion of an embodiment of the present application, Figure 15 is a schematic diagram of the supporting portion of an embodiment of the present application, Figure 16 It is a schematic diagram of the retaining portion of an embodiment of the present application.

[0109] like Figures 14 to 16 As shown, the first guide member 281 of the support portion 28 may be a guide rail ( Figure 14 and Figure 15 ), the second guide member 271 ( Figure 16 The first guide member 281 and the second guide member 271 may be a projection extending radially outward from the main body 273 of the retaining portion 27. By engaging the projection within the guide rail, the retaining portion 27 can be moved along the second rotational trajectory. The present application is not limited thereto, and the first guide member 281 and the second guide member 271 may also be in other forms. For example, the first guide member 281 may be a projection, and the second guide member 271 may be a guide rail or a stepped portion.

[0110] In some embodiments, as Figure 15 As shown, the support portion 28 may include a cylinder portion 282, and the first guide member 281 may be provided on the side wall of the cylinder portion 282. The first guide member 281 may be connected to the cylinder portion 282 in various ways. Figure 15 As shown, using the first guide member 281 as an example, the support portion 28 may further include an eleventh fixing portion 283 and a twelfth fixing portion 284, which are fixed to the sidewall of the barrel portion 282. The eleventh fixing portion 283 abuts the first end L of the first guide member 281, while the twelfth fixing portion 284 abuts the second end K of the first guide member 281. This allows the first guide member 281 to be mounted on the barrel portion 282. The present application is not limited to this embodiment; the first guide member 281 and the barrel portion 282 may alternatively be connected by welding, bonding, or integral molding.

[0111] In some embodiments, the first end L of the first guide member 281 may correspond to the first end of the second rotation trajectory, and the second end K of the first guide member 281 may correspond to the second end of the second rotation trajectory. That is, when the second guide member 271 of the holding portion 27 is located at the first end L of the first guide member 281 of the supporting portion 28, the holding portion 27 is located at the first end of the second rotation trajectory; when the second guide member 271 of the holding portion 27 is located at the second end K of the first guide member 281 of the supporting portion 28, the holding portion 27 is located at the second end of the second rotation trajectory.

[0112] like Figure 15 As shown, the eleventh fixing portion 283 includes a first portion M1 and a second portion M2 extending in the circumferential direction and a third portion M3 extending in the axial direction, wherein the first portion M1 and the second portion M2 respectively limit the first guide member 281 in the axial direction, and the third portion M3 limits the first guide member 281 in the circumferential direction.

[0113] like Figure 15As shown, the third portion M3 can be configured to overlap with at least a portion of the groove of the first guide member 281 in the circumferential direction. Thus, when the second guide member 271 of the retaining portion 27 is located at the first end L of the first guide member 281, the third component can prevent the second guide member 271 of the protecting portion 27 from sliding out of the groove of the first guide member 281.

[0114] like Figure 15 As shown, the twelfth fixing portion 284 includes a fourth portion M4 and a fifth portion M5 extending along the circumferential direction, wherein the fourth portion M4 and the fifth portion M5 respectively limit the first guide member 281 in the axial direction.

[0115] Among them, the twelfth fixing portion 284 can keep the second end K of the first guide member 281 in an open state, so that the second guide member 271 can slide into the groove of the first guide member 281 from the second end of the first guide member 281, making it easy to disassemble or assemble the retaining portion 27 and the supporting portion 28.

[0116] The present application is not limited thereto, and the first end L and the second end K of the first guide member 281 may both be in an open state, or the first end L and the second end K of the first guide member 281 may both be in a closed state; or the first end L of the first guide member 281 is in an open state and the second end K is in a closed state.

[0117] Figure 17 is another schematic diagram of the holding portion and the supporting portion of an embodiment of the present application, Figure 17 FIG shows a state where the holding portion 27 is located at the first end of the second rotation trajectory. Figures 15 to 17 As shown, the support portion 28 may further include a third fixing portion 285 ( Figure 15 and 17 ), the holding portion 27 includes a fourth fixing portion 272 ( Figure 16 and 17 shown in ).

[0118] like Figure 17 As shown, when the holding portion 27 is located at the first end of the second rotational trajectory (for example, the second guide member 271 of the holding portion 27 is located at the first end L of the first guide member 281 of the support portion 28), the third fixing portion 285 is connected to the fourth fixing portion 272. Thus, the holding portion 27 can be accurately located at the first end of the second rotational trajectory.

[0119] In some embodiments, the third fixing portion 285 and the fourth fixing portion 272 can be connected in various ways. Figure 17 As shown, the third fixing portion 285 and the fourth fixing portion 272 are engaged and connected.

[0120] like Figure 15As shown, the third fixing portion 285 may be a protrusion protruding radially inward from the side wall of the cylindrical portion 282 of the support portion 28. Figure 16 As shown, the fourth fixing portion 272 may include a sheet portion 272-1 extending radially outward from the main body portion 273, and an axially extending groove 272-2 is provided on one circumferential side of the sheet portion 1-121. The groove 272-2 engages with the raised portion, thereby connecting the third fixing portion 285 to the fourth fixing portion 272. The present application is not limited to this embodiment, and the first fixing portion 1-12 may also have other structures.

[0121] The fourth fixing portion 272 can be made of a flexible material to facilitate engagement.

[0122] In some embodiments, as Figure 16 As shown, the groove 272-2 can be provided on the extension portion 272-3 extending circumferentially of the sheet portion 272-1, with a gap between the extension portion 272-3 and the main body portion 273. This can increase the elasticity of the first fixing portion 1-12 and improve the convenience of installation or removal.

[0123] In some embodiments, as Figure 15 As shown, the support portion 28 may further include a third limiting portion 286. The third limiting portion 286 includes a sixth portion M6, which is located below the third fixing portion 285. When the holding portion 27 is located at the first end of the second rotational trajectory, the sixth portion M6 can upwardly support the fourth fixing portion 272 of the holding portion 27. Since the first electrical connection portion 13 of the input module 1 is connected to the second electrical connection portion 23 on the holding portion 27 when the holding portion 27 is located at the first end of the second rotational trajectory, the sixth portion M6 can reliably support the holding portion 27.

[0124] In some embodiments, as Figure 15 As shown, the third limiting portion 286 may further include a seventh portion M7, which is located on one circumferential side of the third fixing portion 285. When the holding portion 27 is located at the first end of the second rotational trajectory, the seventh portion M7 can circumferentially abut against the circumferential end of the fourth fixing portion 272 of the holding portion 27. The provision of the seventh portion M7 enables the holding portion 27 to be accurately located at the first end of the second rotational trajectory.

[0125] The following takes replacing the touchpad module with a trackball module as an example to illustrate the replacement process of the input module 1. It is understood that the following description is also applicable to replacing the trackball module with a touchpad module, and the following process can be performed in the reverse order.

[0126] Step 1: Rotate the touchpad module 1-1 along the first rotational trajectory-1, from the end point of the first rotational trajectory-1 to the starting point of the first rotational trajectory-1. During this process, the retaining portion 27 rotates along with the touchpad module 1-1 from the second end of the second rotational trajectory to the first end of the second rotational trajectory. The first fixing portion 1-12 of the touchpad module 1-1 is mechanically disconnected from the second fixing portion 22 of the operating panel 2. The top surface of the touchpad module 1-1 is positioned higher than the top surface of the operating panel 2, making it easier for the user to pull the touchpad module 1-1 upward. At this point, the first electrical connection portion 1-13 of the touchpad module 1-1 is electrically disconnected from the second electrical connection portion 23 of the operating panel 2.

[0127] Step 2: Position the base assembly 1-211 of the trackball module 1-2 at the starting point of the first rotational trajectory-2. For example, press the first electrical connection portion 1-23 of the trackball module 1-2 downwardly into the second electrical connection portion 23 of the retaining portion 27, which is located at the first end of the second rotational trajectory. Rotate the base assembly 1-211 of the trackball module 1-2 along the first rotational trajectory-2, from the starting point to the end point. During this process, the retaining portion 27 rotates along the touchpad module 1-1 from the first end to the second end of the second rotational trajectory. The fifth fixing portion 1-221 of the base assembly 1-211 is mechanically coupled to the seventh fixing portion 221 of the operation panel 2.

[0128] Step 3: The trackball assembly 1-212 of the trackball module 1-2 is rotated along the first rotation trajectory-1, from the starting point of the first rotation trajectory-1 to the end point of the first rotation trajectory-1. At this point, the sixth fixing portion 1-222 of the trackball assembly 1-212 is mechanically connected to the eighth fixing portion 222 of the operation panel 2. This completes the replacement of the touchpad module 1-1 with the trackball module 1-2.

[0130] According to the above embodiment, in the medical input device 100, the input module 1 can be connected to the operation panel 2 in a detachable manner through rotational movement. By moving the input module 1 along the rotational trajectory, when the input module 1 reaches the corresponding position on the rotational trajectory, not only can the mechanical connection between the input module 1 and the operation panel 2 be achieved, but also the electrical connection between the input module 1 and the operation panel 2 can be achieved, which is simple and reliable to operate.

The host 202 may execute control instructions received by the input device 100 and display the execution results of the host 202 through the display screen 201.

[0133] According to the above embodiment, in the medical input device 100, the input module 1 can be detachably connected to the operation panel 2 through rotational motion. By moving the input module 1 along a rotational trajectory, when the input module 1 reaches a corresponding position on the rotational trajectory, not only is the input module 1 mechanically connected to the operation panel 2, but the input module 1 is also electrically connected to the operation panel 2, making operation simple and reliable. By incorporating the above medical input device 100 into the ultrasonic imaging device 200, the user experience can also be improved when using the ultrasonic imaging device 200.
