Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a medical device. Background Technology

[0002] The field of medical devices includes a variety of medical devices, including but not limited to ultrasound imaging devices, electrocardiographs, and monitors. Medical devices include operating components for performing various operations. In addition, for ease of transport, medical devices are usually mounted or integrated into trolleys. For example, a trolley may have an operating table on which the medical device may be mounted, or the operating components of the medical device may be integrated into the operating table on the trolley, allowing the medical device to be operated via the operating table.

[0003] When performing medical procedures using medical devices, the position of the operating table needs to be adjusted to facilitate operation of the device. For example, when performing examinations using ultrasound diagnostic devices, the user (such as a doctor) needs to move the ultrasound probe in the examination area while operating the ultrasound diagnostic device and observing the images on the display. In this case, if the position of the operating table of the ultrasound diagnostic device cannot be adjusted relative to the overall ultrasound diagnostic device, there will be difficulties in the operation.

[0004] Currently, medical devices typically also include movable operating components for adjusting the position of the operating table, such as vertical and / or horizontal positions.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this application and facilitating the understanding of those skilled in the art. Utility Model Content

[0006] The inventors discovered that in some existing structures, the moving operating parts are entirely mechanical, and users adjust the position of the control panel by operating these mechanical parts. However, this structure makes operation difficult. In other existing structures, a motor directly drives the control panel, with the motor's output corresponding to the amount of movement of the control panel. However, this method incurs higher costs. More importantly, it places higher demands on the motor, often requiring a relatively large motor to provide the driving force, which is impractical for many devices, especially compact ones.

[0007] In response to at least one of the above-mentioned technical problems, embodiments of this application provide a medical device.

[0031] When the electric limiting part comes into contact with the lever part, it generates a second electrical signal and sends the second electrical signal to the control part.

[0032] In one or more embodiments, the release mechanism further includes:

[0033] A rotating arm is disposed at the end of the motor shaft and extends radially;

[0063] The embodiments of this application are described in detail below.

[0064] This application provides a medical device. Figure 1 This is a schematic diagram of the structure of a medical device according to an embodiment of this application.

[0065] like Figure 1 As shown, the medical device 10 includes: an operating table 11, a limiting mechanism 12, and a release mechanism 13. The limiting mechanism 12 is connected to the operating table 11 and restricts the movement of the operating table 11. The release mechanism 13 is connected to the limiting mechanism 12 and receives a release operation, causing the limiting mechanism 12 to release the restriction on the movement of the operating table 11.

[0066] Figure 2 This is a schematic diagram of an embodiment of the present application including the release mechanism 13.

[0067] like Figure 2 As shown, the release mechanism 13 includes a switch 14, a motor 15, and a transmission 16. The switch 14 receives a release operation and generates a first electrical signal. The motor 15 is electrically connected to the switch 14 and drives the transmission 16 according to the first electrical signal. The transmission 16, driven by the motor 15, causes the limit mechanism 12 to release the restriction on the movement of the operating table 11.

[0068] It is worth pointing out that, Figure 2The diagram only schematically shows the connector 121 of the limiting mechanism 12 driven by the transmission part 16, but the limiting mechanism 12 may include any limiting structure that cooperates with the connector 121 and connects to the operating table, such as a rotating mechanism that engages via a hook, a lifting prevention mechanism, etc. For example, the limiting mechanism 12 may be a rotary limiting mechanism, which uses a retractable switch to control the rotation and / or locking of the rotating mechanism (e.g., the mechanism that controls the rotation of the operating table 11). Alternatively, the limiting mechanism 12 may also be a lifting limiting mechanism, which may be a switch for a lifting auxiliary mechanism in the art. For example, a switch for a gas spring assembly. When the gas spring switch is not open, the gas spring cannot extend or retract, and the telescopic arm connected to the gas spring cannot move freely, thereby controlling the locking of the lifting of the operating table. When the gas spring switch is open, the gas spring can extend or retract, and the thrust generated by the internal air pressure can be used to assist in lifting the operating table. Similarly, the switch for the above-mentioned lifting auxiliary mechanism may also be a spring assembly switch, which will not be described in detail. In some examples, such as Figure 2 As shown, the limiting mechanism 12 simultaneously controls rotational and lifting limits. Furthermore, in some embodiments, the limiting structure included in the limiting mechanism 12 can be any existing technology, and will not be exhaustively listed. The limiting mechanism 12 can release the restriction on the movement of the operating table by driving the joint portion 121 through the transmission portion 16; related technologies can be consulted, and will not be described in detail here.

[0069] According to the above embodiment, the switch unit receives a release operation and generates a first electrical signal. The motor is electrically connected to the switch unit and drives the transmission unit according to the first electrical signal. Under the drive of the motor, the transmission unit causes the limit mechanism to release the restriction on the movement of the operating table. Thus, the user can operate the switch unit 14, which is easy to operate. Furthermore, the motor 15 drives the transmission unit 16 to release the restriction on the movement of the operating table, eliminating the need for a large motor and saving costs.

[0070] For example, in existing solutions using fully mechanical mobile operating components, users need to perform operations such as pressing, gripping, pushing, and pulling that generate a certain stroke. Especially when users hold it with one hand, the device is prone to jamming due to changes in the direction of force or uneven force, resulting in a poor user experience.

[0071] In this embodiment, the user only needs to operate the switch to generate an electrical signal to drive the motor. This can be achieved by performing a switch operation, such as switching the state of the switch. The operation is simple. In addition, compared with the structure that uses the motor to directly drive the operating table, in this embodiment, the motor 15 only needs to drive the rotating part 16 to release the restriction on the movement of the operating table. This allows the motor 15 to be miniaturized and saves costs.

[0072] For example, in one or more embodiments, the medical device may include a lifting assist mechanism, which includes at least one of a gas spring assembly and a spring assembly, and the limiting mechanism 12 may include a lifting limiting mechanism that releases the restriction on the lifting of the operating table when the release mechanism 13 receives a release operation, and the lifting assist mechanism provides support for the lifting of the operating table.

[0073] Therefore, when the release mechanism 13 receives the release operation, the lifting auxiliary mechanism provides support for the lifting of the operating table. In other words, the motor 15 only needs to drive the rotating part 16 to release the restriction on the movement of the operating table. The motor 15 does not need to provide support for the operating table. In contrast, in the existing structure that uses a motor to drive the operating table, the motor itself also needs to be used to support the operating table. Therefore, compared with the prior art, the embodiment of this application can make the motor 15 smaller and save costs.

[0074] In the embodiments of this application, such as Figure 2 As shown, the transmission unit 16 can be driven by a line, but in this application, it can also be a linkage, for example. This application does not limit it, as long as it can transmit the output of the motor to release the limitation of the limit mechanism on the movement of the operating table.

[0075] like Figure 2 As shown, in one or more embodiments, the medical device 10 may include a control unit 21, and a switch unit 14 is electrically connected to a motor through the control unit 21. That is, a first electrical signal generated by the switch unit is transmitted to the control unit 21, and the control unit 21 generates a corresponding control signal based on the first electrical signal to drive the motor 15, thereby releasing the restriction on the movement of the operating table. The control unit 21 may be, for example, a control board, etc., and this application does not limit it.

[0076] However, this application is not limited to this. For example, the first electrical signal generated by the switch can be directly transmitted to the motor 15 via a cable to drive the motor 15. The following description uses a medical device 10 including a control unit 21 as an example.

[0077] like Figure 2 As shown, in one or more embodiments, the medical device 10 further includes a lever portion 17, a limiting mechanism 12 connected to a first position of the lever portion 17, and a transmission portion 16 connected to a second position of the lever portion 17. Thus, through the lever connection, in an emergency situation where the motor 15 is unexpectedly de-energized, the automatic reset force of the limiting mechanism 12 can overcome the natural force exerted by the motor 15 on the transmission portion 16, thereby automatically resetting the control panel and locking it. The natural force exerted by the motor 15 on the transmission portion 16 refers to the force generated by the motor in the de-energized state due to its inherent damping force, etc.

[0078] The inventors discovered that in existing structures that directly drive the control panel using a motor, the motor stops driving the control panel when the motor suddenly loses power. The state of the control panel becomes unpredictable. For example, the control panel may get stuck or it may displace due to its own weight, overcoming the inherent damping force of the motor in its natural state, which could lead to danger.

[0079] In this embodiment, the transmission unit 16 is connected to the limiting mechanism 12 via the lever unit 17. When the switch unit 14 receives a release operation, the motor 15 drives the transmission unit 16 and overcomes the automatic reset force of the limiting mechanism 12, thereby releasing the limitation of the limiting mechanism 12 on the movement of the operating table. When the state of the switch unit 14 remains unchanged, the motor 15 continues to drive the transmission unit 16, and the operating table remains in the released state. The user can move the operating table as needed. In an emergency situation where the motor 15 loses power unexpectedly, the motor 15 stops driving the transmission unit 16. In this case, the automatic reset force of the limiting mechanism 12 can overcome the natural force of the motor 15 on the transmission unit 16 and automatically reset, and the limiting mechanism 12 resets to the locked state, thereby locking the operating table and ensuring safety.

[0080] Furthermore, by setting up the lever part 17, the force required for the motor drive transmission part to release the limit mechanism can be reduced, which can further miniaturize the motor and save costs.

[0081] However, this application is not limited to this. The transmission part 16 can also be directly connected to the limiting mechanism 12. For example, the transmission part can be a component that can be directly connected to the limiting mechanism 12, such as a line or a connecting rod, so that the limiting mechanism can release the restriction on the movement of the operating table through the transmission part. The following description uses the medical device 10 including the lever part 17 as an example.

[0082] like Figure 2 As shown, in one or more embodiments, the medical device 10 further includes a manual release unit 18 connected to the limiting mechanism 12, the manual release unit 18 receiving a manual release operation and causing the limiting mechanism 12 to release the restriction on the movement of the operating table 11.

[0083] Therefore, by providing the manual release unit 18, the operation table can be moved even in scenarios without power supply. Thus, by integrating the release mechanism 13 and the manual release unit 18, this embodiment of the application enables the motor to release the movement restrictions of the operation table in scenarios with power supply, and the manual release unit to release the movement restrictions in scenarios without power supply, thereby improving the applicability of the medical device.

[0084] like Figure 2As shown, the medical device 10 includes a lever portion 17, a limiting mechanism 12 that can be connected to a first position of the lever portion 17, a transmission portion 16 that can be connected to a second position of the lever portion 17, and a manual release portion 18 that can be connected to a third position of the lever portion 17.

[0085] Therefore, by providing the lever part 17, the transmission part 16 and the manual release part 18 can be positioned at different locations on the lever part, preventing interference between the transmission part 16 and the manual release part 18 and ensuring that the medical device can function properly. In addition, by providing the lever part 17, the manual release part 18 can also release the operating force required by the limiting mechanism 12, further ensuring that it can be easily operated with one hand and improving the feel of operation.

[0086] like Figure 2 As shown, in one or more embodiments, the medical device 10 further includes a mechanical limiting part 19 disposed within the rotational surface of the lever part 17 to limit the rotation angle of the lever part 17, wherein the rotational surface refers to the surface on which the lever part 17 is located during rotation. This not only prevents the rotation angle of the lever part 17, but also inhibits damage and ensures proper operation.

[0087] For example, such as Figure 2 As shown, the mechanical limiting part 19 includes a first mechanical limiting part 19a and a second mechanical limiting part 19b disposed on the same side of the lever part 17. The first mechanical limiting part 19a and the second mechanical limiting part are respectively located on both sides of the rotation center O of the lever part 17 in the direction extending along the lever part. When a release operation or a manual release operation is performed, the lever part 17 rotates around the rotation center O. Figure 2 The lever 17 rotates clockwise within the paper and drives the release mechanism 13 to release the restriction on the movement of the operating table. In this case, the lever 17 can rotate until it contacts the first mechanical limit part 19a. Thus, the first mechanical limit part 19a can limit the maximum rotation angle of the lever 17 during the release process, suppress damage, and ensure good working condition.

[0088] Similarly, when a cancel release operation or a manual release operation is performed, or in the event of an unexpected power outage of the motor, the automatic reset force of the limit mechanism 12 causes the lever part 17 to rotate around the rotation center O. Figure 2 The lever 17 can rotate counterclockwise within the paper. In this case, the lever 17 can rotate until it contacts the second mechanical limit part 19b. Thus, the second mechanical limit part 19b can limit the maximum rotation angle of the lever 17 during the return process of the limit mechanism, suppress damage, and ensure good working condition.

[0089] It is worth noting that, Figure 2The mechanical limiting part 19 shown is merely illustrative and is not intended to limit the scope of this application. For example, the number of mechanical limiting parts 19 may be one to limit the maximum rotation angle during the release or return process, or the number of mechanical limiting parts 19 may be three or more. Furthermore, the position of the mechanical limiting parts 19 may also be in other ways, such as... Figure 2 The diagram shows the mechanical limiting part 19 located above the lever part 17, but this application is not limited to this. The mechanical limiting part 19 may also be located below the lever part 17. Furthermore, when there are two or more mechanical limiting parts 19, the multiple mechanical limiting parts 19 may be located at the upper and lower parts of the lever part 17 respectively. For example, when there are two mechanical limiting parts 19, the two mechanical limiting parts 19 may be located at the upper and lower parts of the lever part 17 respectively. That is to say... Figure 2 The second mechanical limiting part 19b can be located at the lower part of the lever part 17, and can be provided, for example, at the same side relative to the rotation center O and the first mechanical limiting part 19a.

[0090] In this application embodiment, the specific structure of the mechanical limiting part 19 is not limited. For example, it can be rod-shaped. This application does not limit it, as long as it can achieve the limiting function of the lever part 17. It can be selected according to actual needs.

[0091] In addition, such as Figure 2 As shown, in one or more embodiments, the medical device 10 may further include an electrical limiting part 20, which is disposed within the rotational surface of the lever part 17. The electrical limiting part 20 is electrically connected to the control part 21. When the electrical limiting part 20 contacts the lever part 17, it generates a second electrical signal and sends the second electrical signal to the control part 21. Thus, by providing the electrical limiting part 20, not only can damage be suppressed, but the rotational state, i.e., the position, of the lever part can also be detected, thereby detecting collisions, jamming, etc.

[0092] For example, when the lever 17 rotates to a position where it contacts the electric limit part 20a or the electric limit part 20b, the control unit receives a corresponding electrical signal, thereby knowing the position of the lever 17. In addition, the state of the device can be determined by combining the state of the release mechanism and the manual release part. For example, when the lever 17 contacts the electric limit part 20a and the release mechanism and / or the manual release part performs a release action, it indicates that the release mechanism or the manual release part is stuck, or that the device has collided. When the lever 17 contacts the electric limit part 20a and neither the release mechanism nor the manual release part performs a release action, it indicates that the working state is normal. When the lever 17 contacts the electric limit part 20b and neither the release mechanism nor the manual release part performs a release action, it indicates that a collision has occurred, or that the release mechanism or the manual release part is stuck. When the lever 17 contacts the electric limit part 20b and the release mechanism and / or the manual release part performs a release action, it indicates that the working state is normal.

[0093] It is worth noting that, Figure 2 The electrically limiting part 20 shown is merely illustrative and is not intended to limit the scope of this application. For example, the number of electrically limiting parts 20 may be one, or the number of electrically limiting parts 20 may be three or more. Furthermore, the position of the electrically limiting part 20 may also be in other ways, such as... Figure 2 The diagram shows the electric limit part 20 located at the lower part of the lever part 17, but this application is not limited to this. The electric limit part 20 may also be located at the upper part of the lever part 17. Furthermore, when there are two or more electric limit parts 20, the multiple electric limit parts 20 may be located at the upper and lower parts of the lever part 17 respectively. For example, when there are two electric limit parts 20, the two electric limit parts 20 may be located at the upper and lower parts of the lever part 17 respectively. That is to say... Figure 2 The electric limiting part 20b can be located on the upper part of the lever part 17, and can be provided, for example, on the same side relative to the rotation center O and the electric limiting part 20a.

[0094] In this application embodiment, the specific structure of the electric limit part 20 is not limited. For example, the electric limit part 20 may include a spring switch. When the electric limit part is in contact with the lever part 17, the spring switch is turned on, thereby outputting a corresponding second control signal to the control part 21. However, this application is not limited to this. The electric limit part 20 may also have other structures, as long as it can achieve the limit and send a second electrical signal when in contact with the lever part 17. Examples will not be given here.

[0095] In this embodiment, the electric limiter 20a and the electric limiter 20b generate different second electrical signals when they contact the lever 17, thereby enabling the control unit 21 to identify whether the electric limiter 20a and the lever 17 are in contact or whether the electric limiter 20b and the lever 17 are in contact.

[0096] In one or more embodiments, such as Figure 2 As shown, the medical device 10 may include a mechanical limiting part 19 and an electrical limiting part 20, but this application is not limited to this. For example, only the mechanical limiting part or only the electrical limiting part 20 may be provided, depending on actual needs.

[0097] Figure 3 This is a schematic diagram of an embodiment of the present application, including an operating console.

[0098] like Figure 3 As shown, in one or more embodiments, the control panel 11 has a base portion 22, and the motor 15 is disposed on the base portion 22, such as... Figure 1 and Figure 3 As shown, the medical device 10 also includes a gripping portion 23 and a front handle portion 24. A switch portion 14 may be disposed on the gripping portion 23. The front handle portion 24 extends from the end of the gripping portion 23 and is connected to the base portion 22. The switch portion 14 can be connected via a cable disposed in the front handle portion 24. Figure 3 (Not shown in the image) It is electrically connected to the motor 15. This allows the user to release and move the control panel with one hand, improving convenience. Furthermore, by storing the cable within the front handle 24, interference between the cable and other components of the medical device is avoided.

[0099] However, this application is not limited to this. The release mechanism can be set in other ways. For example, the switch part and the motor part can both be set in the base part. This application does not limit this and can set it according to actual needs.

[0100] like Figure 3 As shown, in one or more embodiments, the manual release part 18 may also be provided on the control panel 11, such as the base part 22 of the control panel 11.

[0101] The structure of the release mechanism and the manual release section will be described by way of example below.

[0102] Figure 4 This is a schematic diagram of the switch part 14 of the release mechanism in an embodiment of this application.

[0103] like Figure 4 As shown, in one or more embodiments, the switch portion 14 may be disposed on the grip portion 23. The switch portion 14 may include a release button 25, a switch 26, and a cover 27. For example, the release button 25 and the switch 26 may be assembled on the grip portion 23. The switch 26 may be connected to a cable 29 disposed in a groove 28 of the grip portion 23. The cover 27 covers the switch 26 and the cable 29. The release button 25 is exposed on the grip portion 23. The other end of the cable 29 may be connected to the control portion 21. Thus, a release operation can be performed by pressing the release button 25, for example, by pressing a button.

[0104] It is worth noting that, Figure 4 The switch unit 14 shown is only an example. The structure of the switch unit 14 can also be implemented in other ways, as long as it can receive the user's release operation. Examples will not be given here.

[0105] Figure 5 This is a schematic diagram of a part of the release mechanism in an embodiment of this application, showing the structure associated with the motor 15.

[0106] like Figure 5 As shown, in one or more embodiments, the release mechanism 13 further includes a rotating arm 30 and a motor base 31. The rotating arm 30 is disposed at the end of the shaft of the motor 15 and extends radially. The motor base 31 has a first groove 32 for engaging with the rotating arm 30 and a second groove 33 extending circumferentially. The transmission part 16 includes a wire 34, which can be embedded in the second groove 33. For example, the end 34A of the wire 34 can be fixed to the motor base 31, and the wire 34 extending from the end 34A is embedded in the circumferentially extending second groove 33. The other end 34B can be connected to a limiting mechanism, for example, the limiting mechanism 12 can be connected through the lever part 17. When the motor 15 rotates under the release operation, the end of the rotating shaft of the motor 15 drives the motor base 31 to rotate through the rotating arm 30 and the first groove 32. The angle of the motor base 31 can be a predetermined size, that is, the motor base 31 can rotate within a predetermined range, so that the limitation on the movement of the operating table can be released through the limiting mechanism. The wire 34 is located in the second groove 33, which can prevent the wire 34 from falling off and ensure good device performance.

[0107] In the embodiments of this application, such as Figure 5 As shown, ends 34A and / or 34B of line 34 can be connected to a sphere, thereby facilitating the fixing of line 34, but this application is not limited thereto.

[0108] In the embodiments of this application, such as Figure 5 As shown, the release mechanism may also include, for example, a motor support 36, through which the motor can be mounted on, for example, the base of an operating table.

[0109] It is worth noting that, Figure 5 The structure shown related to the motor 15 is only an example. Other structures can be used to transmit the motor shaft output to the transmission unit, and other structures can be used to fix the motor 15 to the base unit. These will not be listed here.

[0110] Figure 6 This is a schematic diagram of an embodiment of the present application including a transmission unit.

[0111] like Figure 6As shown, in one or more embodiments, the transmission part 16 includes a line 34, the end 34B of which is fixed to, for example, one end of the lever part 17. The other end of the lever part 17 can be connected to a limit mechanism 12, thereby allowing the shaft output of the motor 15 to release the restriction of the limit mechanism 12 on the movement of the operating table through the transmission part.

[0112] In one or more embodiments, such as Figure 6 As shown, the transmission unit 16 may also include a first reverse wheel 37. The line 34 connecting the motor 15 is connected to the lever unit 17 through the first reverse wheel 37. Thus, the direction of the line 34 can be adjusted, the layout of the line 34 is not restricted, and interference with the manual release unit is prevented.

[0113] Figure 6 The transmission unit 16 shown is only an example. The structure of the transmission unit 16 can also be implemented in other ways, as long as the motor can release the restriction of the limit mechanism 12 on the movement of the operating table through the transmission unit. Examples will not be given here.

[0114] Figure 7 This is a schematic diagram of the manual release section in an embodiment of this application.

[0115] like Figure 7 As shown, in one or more embodiments, the manual release unit 18 may be provided on the base portion 22 of the operating table.

[0116] like Figure 7 As shown, in one or more embodiments, the manual release unit 18 includes a base 38, a pull cord 39, and a pull ring 40. The base 38 has opposing first surfaces S1 and second surfaces S2. One end of the pull cord 39 is connected to a limiting mechanism, and the other end 39A of the pull cord 39 passes through the second surface S2 from the first surface S1. The pull ring 40 is exposed outside the second surface S2 and is connected to the other end 39A of the pull cord 39. Thus, by pulling the pull ring 40, the user can release the limiting mechanism from restricting the movement of the operating unit.

[0117] In this embodiment of the application, the connection of one end of the pull wire 39 to the limiting mechanism can be understood as the pull wire 39 being directly connected to the limiting mechanism, or, as... Figure 2 As shown, the pull line 39 is connected to the limiting mechanism 12 via the lever part 17, but this application does not limit this.

[0118] In the embodiments of this application, such as Figure 7 As shown, the manual release unit 18 may also include a locking part 41, which can fix the other end 39A of the pull cable 39 to the pull ring 40, for example, as Figure 7 As shown, the other end 39A of the receiving 39 can be connected to a ball, and the locking part 41 includes a ball socket and a ball cover.

[0119] like Figure 7 As shown, in one or more embodiments, the manual release part 18 may further include a first ferromagnetic material 42, and the pull ring 40 may include a second ferromagnetic material. The first ferromagnetic material 42 indicates that it is made of or comprises a ferromagnetic material. Similarly, the pull ring may be made of or comprise a ferromagnetic material, wherein the ferromagnetic material can be a magnetic or a non-magnetic ferromagnetic material. That is, the first ferromagnetic material 42 may be a magnet, and the second ferromagnetic material may be a non-magnetic ferromagnetic material; or, the first ferromagnetic material 42 may be a non-magnetic ferromagnetic material, and the second ferromagnetic material may be a magnet; or, the first ferromagnetic material 42 may be a magnet, and the second ferromagnetic material may be a magnet.

[0120] In the embodiments of this application, such as Figure 7 As shown, the pull ring 40 is positioned where it can be attracted by the first ferromagnetic material, thereby enabling a good manual release feel. For example, when the manual release is complete, the user can simply release the pull ring 40, which will be attracted to the base 38 by the first ferromagnetic material, providing a good manual release feel.

[0121] In this embodiment, the pull ring 40 can be disposed on the second surface S2 of the base 38 opposite to the first ferromagnetic material 42, but this application is not limited to this, as long as the position of the pull ring 39 is such that the pull ring 40 is attracted by the first ferromagnetic material.

[0122] In the embodiments of this application, such as Figure 7 As shown, the first ferromagnetic material 42 is ring-shaped, and the pull wire 39 can pass through the center of the ring-shaped first ferromagnetic material 42, thereby realizing a compact manual release part. However, this application is not limited to this, and the first ferromagnetic material 42 can also be other shapes. For example, the first ferromagnetic material 42 can be multiple sheet-like portions attached to the first surface S1 of the base 38. This application does not limit this and can choose according to actual needs.

[0123] Figure 8 This is another schematic diagram of an embodiment of the present application, showing the connection between the manual release part and the lever part.

[0124] like Figure 8 As shown, in one or more embodiments, the manual release unit 18 may further include a second reverse wheel 43, through which the pull cable 39 is connected to the lever unit 17, thereby allowing the direction of the pull cable 39 to be adjusted, the layout of the pull cable 39 to be unrestricted, and preventing interference with the release mechanism, for example, preventing interference with the line 34 of the release mechanism.

[0125] It is worth noting that, Figure 7 and 8The manual release unit 18 shown is only an example. The structure of the manual release unit 18 can also be implemented in other ways, as long as the user can release the restriction of the limit mechanism 12 on the movement of the operating table through the manual release unit. Examples will not be given here.

[0126] In the embodiments of this application, the medical device 10 may include both the first reverse wheel 37 and the second reverse wheel 43, thereby increasing the degree of freedom of wiring of the wire 34 and the pull wire 39 and avoiding interference. However, this application is not limited to this. For example, the medical device 10 may include only the first reverse wheel 37 and not the second reverse wheel 43, or the medical device 10 may not include the first reverse wheel 37 and only include the second reverse wheel 43. This application does not limit this and can be set according to actual needs.

[0127] In the embodiments of this application, wire 34 and pull wire 39 can be, for example, Bowden wire, but this application is not limited to this. Wire 34 and pull wire 39 can be other types of wire, as long as they can transmit tensile force.

[0128] In one or more embodiments, the limiting mechanism 12 includes at least one of a lifting limiting mechanism and a rotating limiting mechanism. When either the release mechanism 13 or the manual release part 18 is operated, for example, when the release mechanism 13 receives a release operation and / or the manual release part 18 receives a manual release operation, the limiting mechanism 12 releases the restriction on the lifting and / or movement of the operating table 11.

[0129] For example, such as Figure 2 The limiting mechanism 12 is shown to have two connectors 121, one of which can be used for the lifting limiting mechanism and the other connector 121 can be used for the rotating limiting mechanism. Thus, the user can release the lifting limiting mechanism and the rotating limiting mechanism with one hand, thereby realizing lifting and rotating operations.

[0130] It is understood that the lifting and rotating operations can be implemented in any way available in the prior art. The following description provides examples but does not limit the scope to any particular method.

[0131] For example, in some examples, the medical device may include at least one of a lifting section and a rotating section. The lifting section and the rotating section may be in a locked state, or in other words, the lifting section and the rotating section are normally locked, in which the position of the operating table is locked and cannot be moved. When the lifting section and the rotating section are released from the locked state by operating the release mechanism (switch) and / or the manual release part (pull ring), the user can apply force to the operating table to raise and / or rotate the operating table.

[0132] When the operation on the release mechanism (switch) and / or the manual release part (pull ring) is removed, the lifting part can automatically reset and return to the locked state. For example, the lifting part can be a gas spring, etc., which can achieve automatic reset when the operation on the release mechanism (switch) and / or the manual release part (pull ring) is removed. Alternatively, when the operation on the release mechanism (switch) and / or the manual release part (pull ring) is removed, the lifting part can be in a semi-locked state under the action of the damping component of the lifting part. The semi-locked state means that the lifting part will not move when it is not subjected to external force or when the external force is less than the damping force of the damping component of the lifting part, so the operating table will not rise or fall. For example, when the operating table is at a suitable height, the doctor stops the lifting force applied to the operating table, and the operating table stops rising or falling. When it is necessary to raise or fall the operating table again, the doctor can apply a lifting force to the operating table (lifting platform). If the external force on the lifting part exceeds the damping force of the damping component of the lifting part, the lifting part can move, so the operating table can be raised or lowered. When the lifting part moves to a certain height position, it can return to the locked state.

[0133] Similarly, when the operation on the release mechanism (switch) and / or the manual release part (pull ring) is removed, the rotating part can automatically reset to the locked state or be in a semi-locked state under the action of the damping component of the rotating part. The rotating part may include, for example, a locking structure, such as a convex-concave fit structure, a latch, and a rotating mechanism that engages with the latch. When the locking structure is engaged, the rotating part is locked and the operating table cannot be moved. When the rotating part is released from the locked state by operating the release mechanism (switch) and / or the manual release part (pull ring), the locking structure is not engaged. In this case, the user can apply force to the operating table (rotating part) to rotate it. When the operation on the release mechanism (switch) and / or the manual release part (pull ring) is removed, the rotating part can be locked by the action of the automatic reset component, causing the locking structure to engage again. Alternatively, the rotating part may be in a semi-locked state. When the user rotates the operating table and the force on the rotating part is greater than the damping force of the damping component of the rotating part, the rotating part can continue to rotate and the operating table will rotate. Otherwise, the operating table will not rotate. In addition, when the rotating part rotates to a certain position, the locking structure of the rotating part can re-engage, thereby locking the operating table and preventing it from rotating.

[0134] In this embodiment, the medical device 10 includes at least one of an ultrasound imaging device, an electrocardiograph, and a patient monitor.

[0135] According to the above embodiment, the switch unit receives a release operation and generates a first electrical signal. The motor is electrically connected to the switch unit and drives the transmission unit according to the first electrical signal. Under the drive of the motor, the transmission unit causes the limit mechanism to release the restriction on the movement of the operating table. Thus, the user can operate the switch unit 14, which is easy to operate. Furthermore, the motor 15 drives the transmission unit 16 to release the restriction on the movement of the operating table, eliminating the need for a large motor and saving costs.
