Description

Technical Field

[0001] This specification relates to the field of medical devices, and in particular to an operating device and medical equipment. Background Art

[0002] With the development and popularization of medical imaging equipment and the continuous innovation of the human-computer interaction industry, the pressing force of traditional physical buttons cannot adapt to every operator, resulting in poor operator experience. At the same time, traditional physical buttons are usually faced with various unfavorable factors during operation, resulting in reduced lifespan and increased failure rate. For example, the existing physical buttons include carbon particles and button shrapnel (pot pieces), which rely on their contact with PCBA. During long-term use, medical imaging equipment will have a lot of dust accumulated inside the shell, which will cause a lot of dust to enter the control components, and the entry of dust will cause the buttons to fail. For example, the contrast agent commonly used for auxiliary imaging adheres to the technician's hand. When the technician performs a button operation, the contrast agent will enter the button gap. After solidification, the moving part and the fixed part of the button will adhere, resulting in insensitivity or failure of the button.

[0003] With the rapid popularization of smart mobile devices in the past decade, smart mobile devices with a large number of physical buttons have gradually faded out of the users' field of vision. New user habits and experiences such as touch, borderless large screens, and virtual touch have gradually been formed, leading technicians and hospitals to have similar demands and usage experiences for the control components of medical imaging equipment.

DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of this specification. For ordinary technicians in this field, this specification can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0027] It should be understood that the "system", "device", "unit" and / or "module" used herein are a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0028] As shown in this specification and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "comprise" and "include" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0029] The embodiment of the present specification provides an operating device, which receives user operations through an action unit; obtains the pressure generated by the user's operation on the action unit through a pressure sensing unit, and the operating device can determine whether the user has performed an effective operation. Furthermore, the operating device can also provide the user with perceptible tactile vibration feedback based on the pressure generated by the user's operation on the action unit, so that the user can know the effectiveness of his operation, thereby improving the interactivity of the user's operation.

[0030] Figure 1 is a schematic diagram of the appearance of an operating device according to some embodiments of this specification; Figure 2 is a schematic diagram of the structure of the operating device according to some embodiments of this specification. Figure 1-Figure 2 The following embodiments are understood, but the drawings are only for illustration of some of the embodiments and do not constitute a limitation of the embodiments.

[0031] In some embodiments, Figure 1 and Figure 2 As shown, the operating device 100 includes: an action unit 110 configured to receive a user operation; and a pressure sensing unit 120 configured to obtain the pressure generated on the action unit 110 by the user operation.

[0032] The action unit 110 includes but is not limited to an operation screen, an operation button, etc. For example, the action unit 110 may be an operation screen of the operation device 100, and the user may perform various touch operations on the operation screen.

[0033] Touch operation refers to the operation behavior of the user interacting with the action unit 110. For example, pressing, touching, sliding, long pressing, multi-touch, etc. The user can perform various user operations on the action unit 110 through the fingers, finger joints, palms, etc. or devices such as operating pens.

[0034] In some embodiments, the pressure sensing unit 120 can obtain the pressure magnitude and pressure duration generated by the user operation on the action unit 110. Different user operations correspond to different pressure magnitudes and different pressure durations. In some embodiments, the pressure sensing unit 120 can determine the user's operation type by detecting the pressure magnitude and pressure duration. For example, if the pressure is small and the pressure duration is short, it can be determined that the user's operation type is pressing. In some embodiments, the pressure sensing unit 120 can determine the validity of the user's operation by detecting the pressure magnitude and pressure duration. For example, if the pressure is small and the pressure duration is short, it can be determined that the user has made an accidental touch or an invalid operation.

[0035] In some embodiments, the pressure sensing unit 120 includes a pressure sensor, and when the user operates on the action unit 110, the pressure sensor can detect the pressure generated by the user's operation on the action unit 110. The pressure sensor includes but is not limited to resistive, capacitive, piezoelectric, photoelectric and other types.

[0036] In some embodiments, the pressure sensing unit 120 may include a touch sensor. When the user touches the action unit 110, the touch sensor may detect the local electrostatic field changes generated when the user touches the action unit 110, and determine the touch position. In some embodiments, the pressure sensing unit 120 may determine the touch sliding direction and touch sliding duration of the user on the action unit 110 by detecting the local electrostatic field changes on the action unit 110.

[0037] There is a preset correspondence between different touch sliding directions and / or different touch sliding durations and different touch events. A touch event refers to a corresponding operation performed according to a touch operation. For example, sliding downward indicates that the touch event is to lock the bed and fix the scanner position; sliding upward indicates that the touch event is to unlock the bed and the scanner can be detached. For another example, a long-distance right slide indicates that the touch event is an operation to exit the bed after scanning; a long-distance left slide indicates that the touch event is a scan-in operation to move the scanning bed to the center of the scanner; a short-distance right or left slide indicates that the touch event is to move the bed. A touch event can be determined based on the touch sliding direction and touch sliding duration.

[0038] In some embodiments, the pressure sensing unit 120 may be disposed on the back of the action unit 110. The back of the action unit 110 is the side opposite to the side receiving the user's operation.

[0039] Through the action unit and the pressure sensing unit, the pressure size and pressure duration of the user's operation can be detected to clarify the type of user operation; judging the effectiveness of the user's operation through the pressure sensor helps to avoid erroneous operations caused by accidental touches by the user and improve the user's interactive experience.

[0040] In some embodiments, the action unit 110 is a rectangle or a rounded rectangle, and the pressure sensing unit 120 includes at least four, each of which can generate a sensing signal according to the pressure of the user's operation. According to the sensing signals received by the pressure sensing units 120 at different positions, the position coordinates of the user's touch point can be determined.

[0041] In some embodiments, the distribution positions of at least four pressure sensing units 120 at least include positions corresponding to the four vertex corners of the action unit 110. For example, when there are four pressure sensing units 120, the four pressure sensing units 120 can be respectively set at the positions corresponding to the four vertex corners of the action unit 110. In this embodiment, the pressure sensing unit 120 may include a first pressure sensor, a second pressure sensor, a third pressure sensor, and a fourth pressure sensor located at the upper left corner, the upper right corner, the lower left corner, and the lower right corner, respectively, which generate a first sensing signal, a second sensing signal, a third sensing signal, and a fourth sensing signal, respectively. According to the signal strength difference between the first sensing signal and the second sensing signal, the first horizontal position of the touch point can be determined; according to the signal strength difference between the third sensing signal and the fourth sensing signal, the second horizontal position of the touch point can be determined; the average horizontal position of the touch point can be determined by combining the first horizontal position and the second horizontal position. According to the signal strength difference between the first sensing signal and the third sensing signal, the first longitudinal position of the touch point can be determined; according to the signal strength difference between the second sensing signal and the fourth sensing signal, the second longitudinal position of the touch point can be determined; the average longitudinal position of the touch point can be determined by combining the first longitudinal position and the second longitudinal position; based on the average transverse position and the average longitudinal position, the position coordinates of the touch point can be obtained. Through the joint action of multiple pressure sensing units 120, the user's touch point can be accurately located.

[0042] In some embodiments, the distribution positions of the at least four pressure sensing units 120 may also include positions corresponding to the midpoints of the four sides of the action unit 110. The description of the distribution positions of the pressure sensing units 120 is only an exemplary description, and it can be set according to actual conditions.

[0043] When the action unit 110 is set to a rectangular or rounded rectangular structure, by setting at least four pressure sensing units 120 distributed at the four vertices, it is helpful to determine the specific area position of the user's operation in the action unit 110, so that the operating device 100 can more accurately perceive the user's operation type (different operation areas correspond to different operation buttons, and different operation buttons correspond to different operation types), and effectively perform corresponding operations according to the user's operation. The pressure applied by the user when performing user operations at various positions of the action unit 110 can be obtained by the pressure sensing unit 120, which helps the operating device 100 to determine the effectiveness of the user's operation and avoid misoperation caused by the user's accidental touch. At the same time, since the pressure sensing units 120 are distributed at the four vertices of the action unit 110, the pressure applied by the user on the action unit 110 can be more evenly borne, reducing the wear caused by concentrated pressure. The action unit 110 is a rectangle or a rounded rectangle, which reduces sharp edges and enhances operating comfort.

[0044] In some embodiments, the action unit 110 may be circular, and accordingly, the pressure sensing units 120 include at least three and are evenly distributed along the circumference of the action unit 110. The even distribution means that the spacing between the pressure sensing units 120 is the same or similar.

[0045] When the action unit 110 is set to a circular structure, at least three pressure sensing units 120 are provided to enable the action unit 110 to maintain balance on the shell; at least three pressure sensing units 120 are evenly distributed along the circumference of the action unit 110, which can improve the accuracy of the operating device 100 in detecting the pressure applied by the user on the action unit 110 and the timeliness of the feedback, and improve the response accuracy of the operating device 100 (that is, the operating device 100 can effectively perform corresponding operations according to the user's operation) and user experience.

[0046] In some embodiments, Figure 1 and Figure 2 As shown, the operating device 100 includes a housing 130 , the housing 130 and the action unit 110 are enclosed to form a cavity 101 , and the pressure sensing unit 120 is disposed between the action unit 110 and the housing 130 .

[0047] The housing 130 is used to protect the internal components of the operating device 100 and provide a fixed installation position for the internal components to ensure the overall stability. The housing 130 can be in various forms, such as a rectangular frame, a circular frame, etc.

[0048] In some embodiments, the housing 130 is disposed at the back of the active unit 110 .

[0049] In some embodiments, the projected area of ​​the housing 130 in the axial direction is smaller than the projected area of ​​the action unit 110 in the axial direction. The axial direction refers to the axial direction of the operating device. Figure 2 As shown, the x direction is the axial direction of the operating device.

[0050] The cavity 101 is a region enclosed by the housing 130 and the action unit 110. The cavity 101 can be used to provide a space for installing and arranging the internal components of the operating device 100.

[0051] In some embodiments, the cavity 101 may further include other components, which is not limited in this specification.

[0052] In some embodiments, a pressure sensing unit 120 is disposed between the housing 130 and the action unit 110. In some embodiments, when the action unit 110 is subjected to pressure, there is a relative movement tendency between the housing 130 and the action unit 110, so that the pressure sensing unit 120 can sense the pressure. In some embodiments, there may be a gap between the housing 130 and the action unit 110 where the pressure sensing unit 120 is not disposed, and accordingly, the cavity 101 may be non-enclosed.

[0053] In some embodiments, a pressure sensing unit 120 and a seal are provided between the housing 130 and the action unit 110. The housing 130 can be connected to the action unit 110 through the pressure sensing unit 120 and the seal, and accordingly, the cavity 101 is closed. Exemplary seals can be soft seals (such as cloth tapes, etc.) that do not hinder the pressure on the action unit 110, non-contact seals (such as gap seals, etc.), etc. The provision of seals can prevent dust and other impurities in the external air from entering the cavity 101 and interfering with the normal operation of the internal components of the operating device 100.

[0054] In some embodiments, the pressure sensing unit 120 includes a pressure sensor and a gasket, the pressure sensor is fixedly connected to one of the housing 130 and the action unit 110, and the gasket is abutted or connected to the other of the housing 130 and the action unit 110. For example, when the pressure sensor is fixedly connected to the housing 130, the gasket abuts against the action unit 110. The fixed connection method includes but is not limited to bonding, clamping, etc.

[0055] In some embodiments, the gasket may be made of an elastic material, such as a rubber gasket, a silicone gasket, etc.

[0056] In some embodiments, one end of the gasket may be fixedly connected to the pressure sensor, and the other end may abut or be connected to the housing 130 or the action unit 110 .

[0057] The pressure can be transmitted and detected between the action unit 110 and the pressure sensor through the gasket. When the action unit 110 is not subjected to pressure, the gasket is in an undeformed state. When the action unit 110 is subjected to pressure, the gasket is compressed and transmits the pressure to the pressure sensor. When the pressure sensor is subjected to pressure, the gasket can absorb part of the pressure by deformation to prevent the pressure sensor from being damaged by excessive pressure.

[0058] By setting a fixed connection between the pressure sensor and the housing 130 or the action unit 110, the pressure sensor can be firmly installed in the operating device 100, ensuring stability during user operation and ensuring that the pressure of the action unit 110 can be accurately measured. The design of the gasket abutting against the housing 130 or the action unit 110 can provide elastic feedback for user operation, improve the operating feel, buffer pressure, and prevent the pressure sensor from being damaged by excessive pressure. At the same time, the gasket can maintain a certain distance between the pressure sensor and the action unit 110 or the housing 130, ensuring that the pressure sensor accurately detects pressure and converts it into an electrical signal to transmit to the vibration unit 140. The description of the vibration unit 140 can be found in the following.

[0059] In some embodiments, Figure 2 As shown, the housing 130 includes a connecting portion 131 and a covering portion 132 , wherein the connecting portion 131 is located at one end of the covering portion 132 and extends toward the outside of the covering portion 132 ; the pressure sensing unit 120 is disposed between the acting unit 110 and the connecting portion 131 .

[0060] The connecting portion 131 may be a structure on the shell 130 that provides a connection function between a portion of the external structure and the shell 130. In some embodiments, the pressure sensing unit 120 may be disposed on the connecting portion 131. The connecting portion 131 may be disposed around an end (hereinafter referred to as the connecting end) of the surrounding cover portion 132 that is close to the action unit 110. The connecting portion 131 extends toward the outside of the surrounding cover portion 132. The extension length may be set based on actual needs, such as being greater than or equal to the lateral length of the pressure sensing unit 120. The lateral refers to the horizontal axis direction of the action unit 110. Figure 2 As shown, the y direction is the horizontal axis direction of the action unit 110.

[0061] In some embodiments, the connection portion 131 can be connected to the connection end of the cover portion 132 by bonding, welding, fasteners or integral molding. In some embodiments, the integral molding method can be formed by punching the connection end of the cover portion 132 along a certain curve to turn it into a vertical edge (i.e., by flanging) by relying on the position deformation of the cover portion 132 material. The connection method of the connection portion 131 and the cover portion 132 is only an exemplary description, and the embodiments of this specification do not limit it in any way.

[0062] In some embodiments, the pressure sensing unit 120 is disposed between the action unit 110 and the connection portion 131, and the pressure sensing unit 120 can be connected to the connection portion 131 or one or more of the action unit 110. For example, the pressure sensing unit 120 can be directly connected to the action unit 110 or the connection portion 131 by a fixing method (such as screws, adhesives, etc.) to ensure the stability of the pressure sensing unit 120 during user operation. For another example, the pressure sensing unit 120 is connected to the action unit 110 or the connection portion 131 by a detachable method (such as fasteners, slots, etc.) to periodically check or replace the pressure sensing unit 120. The specific setting method is not limited here.

[0063] In some embodiments, the projection of the connection portion 131 along the axial direction is located within the projection of the action unit 110 along the axial direction. In other words, the projection area of ​​the connection portion 131 along the axial direction is smaller than the projection area of ​​the action unit 110 along the axial direction.

[0064] The cover portion 132 is a structure for covering and storing the internal components of the operating device 100. The shape of the cover portion 132 can be designed to be a rectangular parallelepiped, a cylindrical shape, an elliptical cylindrical shape, etc., which is not limited here. In some embodiments, the cover portion 132 includes a back cover 1323 and a side cover 1321, and the side cover 1321 and the back cover 1323 form a non-enclosed structure, and the opening of the structure is close to and faces the action unit 110.

[0065] In some embodiments, Figure 1 As shown, an opening structure 1322 is provided on the surrounding cover portion 132 , and the opening structure 1322 is used for installing the operating device 100 .

[0066] The opening structure 1322 is used to fix the operating device 100 on the medical device 200. In some embodiments, the operating device 100 can be fixed on the medical device 200 by the cooperation of the tensioning part and the opening structure 1322. The tensioning part can include a screw, a clip, a fastening ring, etc. For example, the operating device 100 can be fixed on the medical device 200 by passing a screw through the opening structure 1322. The opening structure 1322 and the housing of the medical device 200 can be firmly tensioned by the tensioning part.

[0067] In some embodiments, the opening structure 1322 may be disposed on the side cover 1321 of the surrounding cover portion 132. For example, when the housing 130 is rectangular, one or more opening structures 1322 may be disposed on one or more side covers 1321 of the surrounding cover portion 132.

[0068] In some embodiments, Figure 7As shown, when the operating device 100 is fixed to the medical device 200, a mounting hole can be opened on the housing of the medical device 200, and the hole area of ​​the mounting hole can be larger than the axial projection area of ​​the connecting portion 131, and smaller than the axial projection area of ​​the action unit 110. Exemplary medical devices 200 include, but are not limited to, positron emission tomography (PET), electronic computed tomography (CT), ultrasound, magnetic resonance scanning, etc.

[0069] By setting the hole area of ​​the installation hole to be larger than the axial projection area of ​​the connecting portion 131 and smaller than the axial projection area of ​​the action unit 110, the shell 130 can be restricted on the outer shell of the medical device 200, and the action unit 110 can be restricted outside the outer shell of the medical device 200; by setting a suitable opening structure 1322, the operating device 100 can be effectively fixed on the medical device 200, thereby improving the working stability of the operating device 100; at the same time, due to the flange design of the connecting portion 131 on the shell 130, when the operating device 100 is installed on the medical device 200, the shell 130 can be firmly fixed on the medical device 200, thereby further improving the working stability of the operating device 100.

[0070] Figure 3 is a schematic diagram of the structure of the vibration unit according to some embodiments of this specification. Figure 3 The following embodiments are understood, but the drawings are only for illustration of some of the embodiments and do not constitute a limitation of the embodiments.

[0071] In some embodiments, the operating device 100 further includes a vibration unit 140 , which is configured to output vibration feedback based on the pressure, and the vibration unit 140 is disposed in the cavity 101 .

[0072] The vibration unit 140 is a component that outputs vibration feedback. The vibration unit 140 can drive a part or all of the action unit 110 to vibrate through vibration, thereby outputting vibration feedback to the user.

[0073] In some embodiments, the vibration unit 140 may include a base, an electromagnetic coil with an iron core, a moving iron core, a spring sheet, and a vibration sheet. Among them, the electromagnetic coil with an iron core is arranged on the base, and can generate a changing electromagnetic force when powered on. The moving iron core is arranged on the base, and can move closer to or farther away from the electromagnetic coil with the iron core under the action of the electromagnetic force. The spring sheet is connected to the moving iron core and can vibrate back and forth with the moving iron core. The vibration sheet is connected to the spring sheet, and the reciprocating vibration of the spring sheet can apply different forces to the vibration sheet, and the force can cause the vibration sheet to vibrate on the base. The vibration generated by the vibration sheet on the base only acts on the external frame (for example, the bracket 150 or the shell 130), and will not cause vibration of the entire operating device 100.

[0074] In some embodiments, the vibration sheet can be referred to as a vibration part 141. The vibration sheet can generate vibration under the joint action of the electromagnetic coil with an iron core, the moving iron core, and the spring sheet. For more information about the vibration part 141, see below.

[0075] In some embodiments, the vibration unit 140 may output corresponding vibration feedback based on different application pressures of different users on the application unit 110. The vibration feedback corresponding to different application pressures may be different, for example, the vibration intensity is positively correlated with the pressure magnitude and / or the pressure duration, and the specific corresponding relationship may be set according to actual needs.

[0076] In some embodiments, different vibration feedbacks can be adjusted by controlling the current flowing through the electromagnetic coil with the iron core. For example, the vibration intensity can be adjusted by increasing the current or decreasing the current. In some embodiments, the current flowing through the electromagnetic coil with the iron core can be adjusted by PWM adjustment. For example, the vibration intensity and vibration frequency can be adjusted by adjusting the PWM duty cycle.

[0077] In some embodiments, the vibration unit 140 may output vibration feedback when the user operation is valid. The validity of the user operation may be determined based on the pressure of the user operation on the action unit 110. For example, when the pressure magnitude and / or the pressure duration of the action pressure meet the corresponding preset conditions, it may be determined that the user operation is valid. The preset conditions may be set according to actual needs.

[0078] In some embodiments, the vibration unit 140 may output corresponding vibration feedback when the user operation is valid or invalid. The vibration feedback corresponding to the valid and invalid user operations is different, and may be set according to actual needs.

[0079] The vibration unit 140 is used to convert the user's operation on the action unit 110 into tactile feedback, that is, vibration. When the user operates the action unit 110, pressure is generated, and the pressure sensing unit 120 detects the user's operation and obtains pressure information. The pressure information is converted into an electrical signal by related components (such as the circuit board 160 mentioned later). The vibration unit 140 generates vibration under the drive of the electrical signal, and the vibration is fed back to the user (for example, a finger) through the action unit 110, thereby realizing tactile feedback.

[0080] Through the internally arranged vibration unit 140, the corresponding vibration feedback is output according to the pressure applied by the user to the action unit 110 and transmitted to the user, providing the user with real-time and intuitive tactile feedback, so that the user can intuitively perceive whether his operation has been received and processed, effectively improving the user experience.

[0081] The vibration unit 140 may be disposed in various positions within the cavity 101. In some embodiments, the vibration unit 140 may be connected to the action unit 110 and disposed at the back of the action unit 110. The back of the action unit 110 is the side of the action unit 110 opposite to the side of the action unit 110 that receives user operations.

[0082] In some embodiments, other components are disposed inside the cavity 101 , and the vibration unit 140 may be disposed in coordination with the other components.

[0083] Figure 4 is one of the schematic diagrams of the components of the operating device according to some embodiments of this specification. Figure 4 The following embodiments are understood, but the drawings are only for illustration of some of the embodiments and do not constitute a limitation of the embodiments.

[0084] In some embodiments, Figure 4 As shown, a circuit board 160 and a bracket 150 are disposed in the cavity, the bracket 150 is connected to the action unit 110 , the circuit board 160 is connected to the bracket 150 , and the vibration unit 140 is connected to the circuit board 160 .

[0085] In this embodiment, the bracket 150 is connected to the housing 130 inside the cavity 101 .

[0086] In this embodiment, the vibration unit 140 can transmit the vibration to the action unit 110 through the circuit board 160 and the bracket 150 in sequence. For more information about the circuit board 160 and the bracket 150, see below.

[0087] In this embodiment, the vibration unit 140 can be of various types such as a piezoelectric vibrator and an electromagnetic vibrator.

[0088] In some embodiments, Figure 3 As shown, the vibration unit 140 includes a vibration part 141 and a fixing part 142 connected to each other, the fixing part 142 is relatively fixed to the housing 130, and the vibration part 141 is connected to the action unit 110. When the vibration unit 140 is composed of the vibration part 141 and the fixing part 142, the vibration unit 140 can be connected to other components of the operating device 100 through other connection methods. For more information about this embodiment, see Figure 5 .

[0089] The vibration part 141 is a component that generates vibration in the vibration unit 140. The vibration part 141 may include one or more.

[0090] In some embodiments, the vibration unit 141 may be fastened to the action unit 110. In some embodiments, the vibration unit 141 may be fastened to the center of the action unit 110. In some embodiments, the vibration unit 141 may also be fastened to the user operation area in the action unit 110. The user operation area is an area where the user inputs user operations.

[0091] In some embodiments, the vibration unit 141 may include a vibration motor. When the vibration motor operates, it generates vibration and transmits the vibration to the user through the action unit 110 to form vibration feedback.

[0092] The fixing part 142 is a component that provides stable support for the vibration part 141, ensuring the stability of the vibration part 141 when generating vibration feedback. In some embodiments, the fixing part 142 can be fixedly connected to one end of the connecting part 131, thereby providing stable support for the vibration part 141. The fixing part 142 can include at least one.

[0093] In some embodiments, the fixing portion 142 is relatively fixed to the housing 130. In some embodiments, the fixing portion 142 may be connected to the bracket 150, and the bracket 150 is connected to the housing 130, thereby achieving relative fixation between the fixing portion 142 and the housing 130. For more information about the bracket 150, see below.

[0094] When the vibration part 141 vibrates, the stability of the fixing part 142 can effectively reduce the impact on other components of the operating device 100, prevent the vibration of the vibration part 141 from causing other components inside the operating device 100 to move or vibrate, ensure the effective transmission of the vibration and reduce its impact on other components inside the operating device 100, thereby improving the overall stability and reliability of the operating device 100.

[0095] In some embodiments, the vibration part 141 includes a plate-like structure 1411, one end of the plate-like structure 1411 connected to the action unit 110 is a vibration output end, and the other end of the plate-like structure 1411 is connected to the fixed part 142. In some embodiments, when the vibration part 141 vibrates, the amplitude of the vibration output end of the plate-like structure 1411 is the largest, and the amplitude of the end of the plate-like structure 1411 connected to the fixed part 142 is much smaller (e.g., less than 10%) than the vibration output end (which can be regarded as not vibrating). With such a configuration, the vibration signal generated by the vibration unit 140 can be transmitted only to the action unit 110, and will not be transmitted to the housing 130 through the bracket 150, thereby avoiding the vibration signal from affecting the pressure sensing unit 120.

[0096] The plate-like structure 1411 is a structure for generating and transmitting vibration. In some embodiments, the plate-like structure 1411 is made of a material that can effectively transmit vibration, such as metal, plastic, or synthetic resin. In some embodiments, the plate-like structure 1411 can be a leaf spring.

[0097] The vibration of the plate-like structure 1411 can be driven in a variety of ways. In some embodiments, the plate-like structure 1411 is a piezoelectric beam and is driven by an electrical signal. When the piezoelectric beam receives the electrical signal, the piezoelectric beam will produce mechanical deformation due to the piezoelectric effect, thereby causing the piezoelectric beam to vibrate, and the vibration is fed back to the user through the vibration output end of the action unit 110 to achieve tactile feedback. In some embodiments, the plate-like structure 1411 can be an electromagnetic material and driven by an electromagnetic. When the circuit board receives an electrical signal converted from pressure, a magnetic field is generated using the principle of electromagnetic induction, thereby causing the plate-like structure 1411 to vibrate, and the vibration is fed back to the user through the vibration output end of the action unit 110 to achieve tactile feedback.

[0098] Through the above-mentioned setting, the vibration output end of the plate-like structure 1411 is connected to the action unit 110, so that the vibration is directly and efficiently transmitted from the vibration unit 140 to the action unit 110, thereby improving the vibration transmission efficiency; the other end of the plate-like structure 1411 is connected to the fixing part 142 to prevent the vibration signal from being transmitted to the structure outside the action unit 110.

[0099] Figure 5 It is one of the schematic diagrams of the components of the operating device according to some embodiments of this specification; Figure 6 is a schematic diagram of the structure of the operating device shown in some embodiments of this specification. Figure 5 , Figure 6 The following embodiments are understood, but the drawings are only for illustration of some of the embodiments and do not constitute a limitation of the embodiments.

[0100] In some embodiments, Figure 5 , Figure 6 As shown, a circuit board 160 and a bracket 150 are arranged in the cavity, the bracket 150 is connected to the housing 130, and the circuit board 160 and the fixing part 142 ( Figure 6 Not shown) are respectively connected to the bracket 150.

[0101] The circuit board 160 is a component for controlling the operation of the pressure sensing unit 120 and the vibration unit 140. For example, the circuit board 160 can drive the vibration unit 140 to generate corresponding vibration feedback according to the pressure change caused by the user operation on the action unit 110. In some embodiments, the circuit board 160 is connected to the bracket 150 (such as by welding, clamping, etc.) to ensure its stability in the operating device 100 and prevent displacement or damage due to vibration or external force.

[0102] The bracket 150 is a structure for providing support for some components inside the cavity 101. In some embodiments, the bracket 150 can be connected to the housing 130 in the cavity 101. In some embodiments, there is a storage space between the bracket 150 and the housing 130. In some embodiments, the storage space can be used for the circuit board 160. In some embodiments, the storage space can also be used for the vibration unit 140.

[0103] In some embodiments, the bracket 150 may be constructed of materials including, but not limited to, metal, plastic, or composite materials.

[0104] The bracket 150 can provide support for the internal components of the housing 130, ensuring the stable position of the circuit board 160 and the fixing portion 142 inside, so as to achieve more precise operational tactile feedback, thereby improving the user experience and operational accuracy of the medical device.

[0105] In some embodiments, the vibration unit 140 may be connected to the bracket 150. In some embodiments, the fixing portion 142 of the vibration unit 140 may be connected to the bracket 150, and the vibration portion 141 of the vibration unit 140 may be connected to the action unit 110.

[0106] In some embodiments, the bracket 150 may be disposed between the fixing portion 142 and the circuit board 160 , and connected to the housing 130 .

[0107] In some embodiments, elastic members may be provided between the action unit 110 and the vibration part 141, between the fixing part 142 and the bracket 150, between the bracket 150 and the circuit board 160, and / or between the circuit board 160 and the housing 130 to achieve a soft connection between the various components, which helps the pressure sensing unit 120 detect pressure. For example, the elastic member may be an elastic material such as a rubber member.

[0108] By forming the device base of the operating device 100 with the fixing part 142, the bracket 150, the circuit board 160 and the shell 130, it can effectively ensure that the pressure sensing unit 120 stably detects the pressure generated by the user's operation, reduce the interference of the vibration part 141 on the pressure sensing unit 120, and at the same time, the device base can enable the operating device 100 to be firmly installed on various medical devices; when the operating device 100 is installed on the medical device 200 through the mounting holes described above, the device base can be tightly connected to the medical device 200, and the action unit 110 and the vibration unit 140 can still obtain good degrees of freedom, thereby obtaining a good vibration effect; by connecting the vibration part 141 of the vibration unit 140 to the action unit 110, the distance between the vibration unit 140 and the action unit 110 can be reduced, and the response speed can be improved so that the vibration generated by the vibration unit 140 can be transmitted to the action unit 110 through the bracket 150 more quickly, providing the user with pressure-sensitive tactile feedback in a timely and effective manner.

[0109] In some embodiments, the vibration unit 140 includes an electromagnetic vibration unit 143 , and the operating device 100 further includes an electromagnetic shielding unit.

[0110] The electromagnetic vibration unit 143 is an element (such as an electromagnetic coil) for receiving an electrical signal and generating a magnetic field. The electromagnetic vibration unit 143 can generate a magnetic field based on the electrical signal, and the vibration part 141 (for example, the plate-like structure 1411) can vibrate under the action of the magnetic field. In some embodiments, the electromagnetic vibration unit 143 can change the characteristics of the generated vibration by changing the characteristics of the input electrical signal (such as amplitude, frequency, etc.), thereby changing the tactile feedback felt by the user and improving the user's operating experience.

[0111] The electromagnetic shielding unit is used to prevent the electromagnetic vibration unit 143 from generating electromagnetic interference on other components inside the operating device 100, thereby avoiding the influence on other components. For example, the electromagnetic shielding unit can be a shielding cover or shielding shell made of high magnetic permeability material (such as iron, nickel, cobalt, etc.).

[0112] In some implementations, the electromagnetic shielding unit includes an electromagnetic glass and a shielding layer, the electromagnetic glass is disposed inside the action unit 110 , and the shielding layer is disposed on the inner wall of the housing 130 .

[0113] In some embodiments, the shielding layer may also be disposed at other locations of the operating device 100. For example, the shielding layer may be disposed around the bracket. The location of the shielding layer is only an exemplary description, and it may be disposed according to actual needs.

[0114] The electromagnetic shielding unit adopts the structure of electromagnetic glass and shielding layer, which effectively improves the electromagnetic shielding effect, reduces the interference of the electromagnetic field on other components of the operating device 100, and ensures the stability of the operating device 100.

[0118] In some embodiments, the glass cover plate 1111 is located at the uppermost layer of the touch screen 111, and the user can touch the glass cover plate 1111 with a finger. The glass cover plate 1111 can prevent the display module 1113 and the TP layer 1112 from being damaged.

[0119] The TP layer 1112 is located in the middle layer of the touch screen 111, and includes a sensor array for sensing pressure generated by user touch. When the user touches the glass cover 1111, the TP layer 1112 can obtain the pressure generated by the user's touch and transmit it to the pressure sensing unit 120. For example, the TP layer 1112 can sense the user's touch behavior through resistive, capacitive, infrared or surface acoustic wave technology and convert it into an electronic signal.

[0120] In some embodiments, when the vibration unit 140 includes an electromagnetic vibration unit, the electromagnetic glass of the electromagnetic vibration unit is disposed inside the action unit 110. In some embodiments, the electromagnetic glass may be disposed between the glass cover plate 1111 and the TP layer (Touch Pane) 1112.

[0122] The support frame 112 is a frame structure that provides support for the touch screen 111. For example, the support frame 112 can be made of plastic, metal, or synthetic materials. In some embodiments, the support frame 112 can be connected to the pressure sensing unit 120 and the vibration unit 140. In some embodiments, the support frame 112 can be connected to the pressure sensing unit 120 and the bracket 150.
