Description

Technical Field

[0002] Lifting platforms are widely used in medical equipment. For example, when the medical equipment is a medical imaging system, radiation from a radiation source is directed toward an object to be detected, which is usually a patient in a medical diagnosis application. A portion of the radiation passes through the object to be detected and is received by a detector, which generates an output signal based on the amount or intensity of radiation received by the detector. The output information is processed to generate a medical image that can be displayed for inspection.

[0003] For the supine scanning method, usually, the object to be detected needs to lie on a lifting platform in a supine position. The lifting platform includes a base and a support platform arranged on the upper side of the base. A support assembly is arranged between the base and the support platform, and the support assembly drives the support platform to move so as to move the object to be detected located on the support platform to a desired position.

[0035] In an embodiment of the present application, the lifting platform can be applied to various devices. The device includes, for example, medical equipment, or industrial equipment. Taking medical equipment as an example, the medical equipment includes, for example, equipment related to various medical imaging scenarios. The medical imaging scenarios include, but are not limited to, magnetic resonance imaging (MRI), computed tomography (CT), ultrasound imaging, X-ray imaging, positron emission tomography (PET), single photon emission computed tomography (SPECT), PET / CT, PET / MR or any other suitable medical imaging scenarios.

[0036] In the embodiments of the present application, the lifting platform and medical equipment of the present application are exemplarily described by taking the CT scene as an example. Those skilled in the art will understand that the present application is also applicable to other radiation imaging systems or imaging systems based on other high-frequency electromagnetic energy.

[0037] Figure 1 FIG. 1 is a schematic diagram of a CT system for CT imaging according to an embodiment of the present application. Figure 1 As shown, the CT system 100 is used to image a scan object 112 (eg, a patient, an inanimate object, an implant, a stent and / or a contrast agent present in the body, etc.).

[0038] The CT system 100 includes a lifting platform 101. A scanning object 112 lies on the lifting platform 101. The lifting platform 101 drives the object 112 to move, for example, along Figure 1 At least one of the coordinate axes X, Y, and Z in the image is displaced.

[0039] The CT system 100 includes a gantry 102. An X-ray source 104 is mounted on the gantry 102 and is used to emit an X-ray beam 106 for imaging a scan object 112. Specifically, the X-ray source 104 is used to project the X-ray beam 106 toward a detector assembly 108 positioned on the opposite side of the gantry 102.

[0040] In some embodiments, the X-ray source 104 emits a fan-shaped / conical beam of rays, which is collimated into an XYZ plane located in a Cartesian coordinate system, i.e., an imaging plane. The X-ray beam passes through the scanned object 112 and is attenuated by the scanned object 112 before being projected onto the detector assembly 108. Therefore, the intensity of the rays received on the detector assembly 108 depends on the attenuation degree of the rays by the scanned object 112. The detector assembly 108 may include a plurality of detector units forming an array, each of which detects a signal representing the intensity of the corresponding beam of rays. The signals detected by each detector unit may be used as distributed projection data (or image data) for subsequent processing.

[0041] In some embodiments, the CT system 100 further includes an image reconstructor 110, which is used to receive the projection data and perform image reconstruction to obtain a volume image of the scanned object 112, which may specifically include a three-dimensional volume image or an image corresponding to one or more two-dimensional slices of the scanned object 112. The reconstructed image may be transmitted to a processing device and stored in a large-capacity memory coupled to the processing device.

[0042] Figure 2 is another schematic diagram of a CT system for CT imaging according to an embodiment of the present application. Figure 2 The CT system 200 shown is Figure 1 The CT system 100 shown is similar. Figure 2 As shown, the CT system 200 is used to scan an object 204 (eg Figure 1 The scanned object 112) is imaged.

[0043] The CT system 200 includes a detector assembly 108, which includes a plurality of detector units 202 that collectively detect an X-ray beam 106 that passes through a scanned object 204 to acquire corresponding projection data. In one example, the detector assembly includes a plurality of rows of detector units 202 that can be used to acquire projection data corresponding to a plurality of slices. The detector units 202 can be energy integrating detectors, photon counting detectors, energy discriminating detectors, or any other suitable radiation detectors. The detector units 202 can employ scintillators and generate analog signals, and the detector units 202 can also be direct conversion detectors (i.e., detectors that do not employ scintillation), such as detectors based on silicon strips or other semiconductor materials, which generate measurable signals when the semiconductor sensors themselves are exposed to X-rays.

[0044] In some embodiments, the CT system 200 further includes a beam limiter assembly 220, which can be positioned in the propagation direction of the X-ray source 104 and adjacent to the X-ray source, and the beam limiter assembly 220 can limit the shape and / or range of the high-intensity region of the X-ray beam 106 to limit the X-ray exposure of the portion outside the region of interest of the scanned object 204. Specifically, the beam limiter assembly 220 can be installed between the X-ray source 104 and the scanned object 204 and positioned close to the X-ray source 104. The beam limiter assembly 220 can include one or more blades (or baffles), the one or more blades forming an opening, the one or more blades being used to block a portion of the X-rays, and the opening being used to pass another portion of the rays, thereby limiting the shape and / or range of the projected X-ray beam.

[0045] In some embodiments, the CT system 200 may further include a collimator (not shown), which may be disposed between the scanned object 204 and the detector assembly 208 and adjacent to the detector assembly 208. The collimator is generally made of a material that blocks or absorbs X-rays, so that the X-rays reflected or deflected by the scanned object 204 can be blocked by the collimator to prevent them from being projected to the detector assembly 208. On the contrary, the X-rays 106 traveling in a relatively straight path from the X-ray source 104 to the detector assembly 208 are not blocked by the collimator 222 and can be projected to the detector assembly 208.

[0046] In some embodiments, the CT system 200 further includes a control mechanism 208, which may include an X-ray controller 210 and a gantry motor controller 212. During a scan to acquire projection data, the X-ray controller 210 is used to control the operation of the X-ray source 104 (e.g., providing power and timing signals to the X-ray source 104, and determining / tracking the focus / focal spot position of the X-ray source), and the gantry motor controller 212 is used to control the gantry 102 and components mounted thereon to rotate around the scanned object 112 at an appropriate speed based on imaging requirements, so that the angle / position at which the X-ray beam 106 intersects the scanned object 112 is constantly changing. The projection data acquired by the detector assembly 108 at each angle is called a view, and a scan performed on the scanned object 112 includes a set of views obtained at different angles during one rotation of the X-ray source 104 and the detector assembly 108 around the scanned object 112.

[0047] In some embodiments, the control mechanism 208 further includes a lift motor controller 215, which can further control the lift 228 (eg, Figure 1 Specifically, the lifting platform motor controller 215 can move the lifting platform 228 so that the scanning object 204 on the lifting platform 228 moves completely or partially through Figure 1The opening of the gantry 102 is opened to position the scan object 204 in a scan area defined by the gantry 102 to acquire projection data corresponding to the scan object 204.

[0048] In some embodiments, the control mechanism 208 further includes a beam limiter assembly controller 213, which is used to control the operation of the beam limiter assembly 220. For example, the movement of one or more blades of the beam limiter assembly 220 (or the beam limiter assembly 300 described below) can be controlled to adjust the position or width of the opening. In some embodiments, such adjustment can be performed based on the result of the X-ray controller 210 tracking the focus of the X-ray source.

[0049] The detector array composed of the detector units 202 includes a full shadow area for receiving full shadow data and a penumbra area for receiving penumbra data. When the X-ray source 104 emits an X-ray beam 106 at different focal spot positions, the full shadow area can receive the X-ray beams at all focal spot positions, while the penumbra area may only receive the X-ray beams emitted at a portion of the focal spot positions. In some embodiments, the full shadow area is usually formed into a regular array (e.g., a rectangle) to adapt to the shape of the X-ray beam limited by, for example, a beam limiter assembly 220 having a square opening. In order to track the focal spot position, it is necessary to set an additional small number of detectors at the edge portion outside the regular array to form the above-mentioned penumbra area, so that an irregular shape is formed as a whole, and the design cost is relatively high.

[0050] In some embodiments, the CT system 200 further includes a data acquisition system (DAS) 214 for sampling and digitizing data received by the detector unit 202 to convert it into projection data. The data sampled and digitized by the DAS 214 is transmitted to a processing device 216 as further described herein.

[0051] The processing device 216 may include a computer device. In one example, the processing device 216 stores data in a storage device or mass storage 218, or the data sampled and digitized by the DAS 214 is directly transferred to the mass storage 218. For example, the storage device 218 may include a hard drive, a floppy drive, a compact disk-read / write (CD-R / W) drive, a digital versatile disk (DVD) drive, a flash drive, and / or a solid-state storage drive, etc. An associated display 232 allows an operator to observe reconstructed images and other data from the processing device. The display 232 may also allow an operator to select a region of interest and / or request patient information via a graphical user interface for subsequent processing.

[0052] In some embodiments, the CT system 200 further includes an operator console 234, which is operably coupled to the processing device 216, and the processing device 216 can receive instructions and parameters input by the operator through the operator console 234. The operator console has some form of operator interface, such as a keyboard, a mouse, a voice-activated controller, or any other suitable input device.

[0053] In addition, the processing device 216 is used to send commands or parameters to one or more of the DAS 214, the X-ray controller 210, the gantry motor controller 212, the beam limiter assembly controller 213, and the elevator motor controller 215 to control system operations, such as data acquisition and / or processing. The processing device 216 can control system operations based on operator input.

[0054] In some embodiments, the processing device 216 may calculate parameters (e.g., Z ratio) for tracking the focus of the X-ray source 104 based on the penumbra data and the full shadow data in the data received from the DAS, and send the parameters to the X-ray controller 210, and the X-ray controller 210 tracks the focus position of the X-ray source 104 based on the received parameters (e.g., Z ratio). The processing device 216 may also receive the result of the focus tracking from the X-ray controller 210, and send it to the beam limiter assembly controller 213, so as to be able to control the operation of the beam limiter assembly 220 (or the beam limiter assembly 300) based on the current focus position.

[0055] In some embodiments, the CT system 200 includes an image reconstructor 230 for receiving projection data from the DAS 214 and performing image reconstruction, and the reconstructed image can be transmitted to a processing device 216 to generate patient information for diagnosis and evaluation. The processing device 216 is used to store the reconstructed image and patient information in a mass storage 218. In some embodiments, the processing device 216 can transmit the reconstructed image to a display 232, which can be communicatively coupled to the processing device 216 and / or the image reconstructor 230.

[0056] The above only describes an example of a CT system suitable for applying the embodiments of the present application. Those skilled in the art will recognize that the embodiments of the present application can also be applied to any imaging system or device based on other radiation or high-frequency electromagnetic energy.

[0057] Figure 3 Schematic diagram of a lifting platform according to an embodiment of the present application. Figure 3 As shown, the lifting platform 300 includes a base 301 , a support platform 302 , a support assembly 303 , a driving assembly 304 , a locking assembly 305 , and a locking state switching assembly 306 .

[0058] like Figure 3As shown, the support platform 302 is disposed on the upper side of the base 301. The support assembly 303 connects the support platform 302 and the base 301. The driving assembly 304 is connected to the support assembly 303 and drives the support assembly 303 to move so as to lift the support platform 302.

[0059] The locking assembly 305 is connected to the supporting assembly 303 to lock the movement of the supporting assembly 303. The locking state switching assembly 306 is detachably connected to the locking assembly 305 to switch the locking state and the unlocking state of the locking assembly 305.

[0060] When the locking state switching component 306 is connected to the locking component 305, the locking component 305 is in an unlocked state, and the supporting component 303 can move freely; when the locking state switching component 306 is separated from the locking component 305, the locking component 305 is in a locked state, and the movement of the supporting component 303 is blocked.

[0061] According to the above embodiment, a locking component 305 capable of preventing the movement of the supporting component 303 of the lifting platform 300 and a locking state switching component 306 detachably connected to the locking component 303 are provided in the lifting platform 300. When the locking state switching component 306 is connected to the locking component 305, the locking component 305 is in an unlocked state, and the supporting component 303 can move freely; when the locking state switching component 306 is separated from the locking component 305, the locking component 305 is in a locked state, and the movement of the supporting component 303 is prevented. That is, by separating the locking state switching component 306 from the locking component 305, the locking component 305 can be switched from an unlocked state to a locked state to lock the lifting platform 300. Thus, the locking operation can be simplified, which helps to avoid safety problems. In addition, by connecting the locking state switching component 306 to the locking component 305, the locking component 305 is switched from a locked state to an unlocked state to unlock the lifting platform 300. Thus, it helps to avoid unlocking the lifting platform 300 due to misoperation, which helps to avoid safety problems.

[0062] In some embodiments, Figure 3 As shown, when the locking state switching component 306 is connected to the locking component 305, the locking state switching component 306 can cover the component to be repaired of the support component 303 or the drive component 304. For example, the locking state switching component 306 can cover at least a portion of the component to be repaired.

[0063] According to the above structure, if the user wants to repair the parts to be repaired, he needs to first release the cover of the locking state switching component 306 on the parts to be repaired; if he wants to release the cover, he needs to first separate the locking state switching component 306 from the locking component 305. As mentioned above, when the locking state switching component 306 is separated from the locking component 305, the locking component 305 switches from the unlocked state to the locked state, and the movement of the supporting component 303 is blocked, thereby avoiding the support table 302 from unexpected displacement or decline.

[0064] Thus, through the above structure, the lifting platform 300 can be reliably locked before the repaired parts are repaired, thereby realizing the poka-yoke function, providing reliable safety protection, and effectively avoiding safety problems. In addition, the locking state switching component 306 can not only cover the parts to be repaired, but also switch the locking state of the locking component 305, thereby realizing the poka-yoke function with fewer components, which helps to simplify the structure of the lifting platform 300.

[0065] In some embodiments, the lock state switching component 306 can be any structure capable of covering or shielding the component to be repaired. Figure 4 Schematic diagram of a lock state switching component according to an embodiment of the present application. Figure 4 As shown, the locking state switching assembly 306 may be a housing, thereby being able to reliably cover or shield the component to be repaired.

[0066] like Figure 4 As shown, the locking state switching component 306 includes a shielding portion 3061 and a claw portion 3062. The shielding portion 3061 is used to cover or shield the component to be repaired, and the claw portion 3062 is used to connect with the locking component 305, wherein the specific connection method will be described in the following content.

[0067] In some embodiments, the parts to be repaired of the lifting platform 300 may include the connection parts of the support assembly 303 and the drive assembly 304. Thus, before the drive assembly 304 is repaired or replaced, it is possible to ensure that the lifting platform 300 is in a locked state, so that the support platform 302 will not suddenly drop due to the repair or removal of the drive assembly 304. The present application is not limited thereto, and the parts to be repaired may also be other parts of the lifting platform 300.

[0068] In some embodiments, the connection portion connecting the driving assembly 304 and the supporting assembly 303 can be in various forms. Figure 5 Schematic diagram of the connection part of the embodiment of the present application. Figure 5 As shown, the connection portion 307 may include at least one screw, and the at least one screw fixes one end of the driving assembly 304 to the supporting assembly 303 .

[0069] The structure of the support assembly is exemplarily described below with reference to the accompanying drawings.

[0070] like Figure 3 As shown, the support assembly 303 may include a first support portion 3031 and a second support portion 3032 arranged crosswise. For example, the support assembly 303 is in the form of scissors, and two scissor arms (i.e., the first support portion 3031 and the second support portion 3032) are connected by an axis 3033, wherein the two scissor arms can rotate around the axis 3033.

[0071] The upper ends of the first supporting part 3031 and the second supporting part 3032 are connected to the support platform 302 , and the lower ends of the first supporting part 3031 and the second supporting part 3032 are connected to the base 301 .

[0072] Figure 6 Schematic diagram of the support assembly, locking assembly and locking state switching assembly of the embodiment of the present application. Figure 6 As shown, in the support assembly 303, the first support portion 3031 includes two arms 3031a and 3031b arranged opposite to each other. The second support portion 3032 can be located between the two arms 3031a and 3031b. That is, the two arms 3031a and 3031b clamp the second support portion 3032. The two arms 3031a and 3031b of the first support portion 3031 are fixedly connected and rotate synchronously around the axis 3033.

[0073] In some embodiments, Figure 6 As shown, the second support part 3032 may also include two arms 3032a and 3032b. The two arms 3032a and 3032b of the second support part 3032 are arranged between the two arms 3031a and 3031b of the first support part 3031. The two arms 3032a and 3032b of the second support part 3032 are fixedly connected and rotate synchronously around the axis 3033. Thus, the strength of the support assembly 303 can be ensured, and the support platform 302 can be stably supported.

[0074] For ease of description, in the following description, the space between the two arms 3031a and 3031b of the first support portion 3031 is referred to as the inner side of the first support portion 3031, and correspondingly, the side of the arm 3031a away from the arm 3031b and the side of the arm 3031b away from the arm 3031a are referred to as the outer side of the first support portion 3031.

[0075] Similarly, the space between the two arms 3032a and 3032b of the second support portion 3032 is called the inner side of the second support portion 3032, and correspondingly, the side of the arm 3032a away from the arm 3032b and the side of the arm 3032b away from the arm 3032a are called the outer side of the second support portion 3032.

[0076] The above is only an exemplary description of the support assembly 303, wherein the support assembly 303 may also be other structures, and the present application does not impose any specific limitation on this.

[0077] The following is an exemplary description of the manner in which the driving assembly drives the supporting assembly in conjunction with the accompanying drawings.

[0078] In some embodiments, the driving component 304 is, for example, a cylinder, a hydraulic cylinder, a linear actuator, or a ball screw.

[0079] like Figure 3 As shown, the lower end of the driving assembly 304 is connected to the base 301, as shown in FIG. Figure 5 As shown, the upper end of the driving assembly 304 is connected to at least one of the first supporting portion 3031 and the second supporting portion 3032 through the connecting portion 307. By adjusting the inclination angle of the first supporting portion 3031 or the second supporting portion 3032, the height of the upper end of the first supporting portion 3031 and the upper end of the first supporting portion 3032 are adjusted, thereby adjusting the height of the support platform 302.

[0080] The above is merely an exemplary description of the manner in which the driving assembly drives the supporting assembly, wherein the driving assembly 304 may also drive the supporting assembly 303 in other manners, and the present application does not impose any specific limitation on this.

[0081] The structure of the locking assembly is exemplarily described below with reference to the accompanying drawings.

[0082] Figure 7 and Figure 8 is a schematic diagram of a partial structure of a locking assembly and a first supporting portion of an embodiment of the present application, Fig. 9 and Fig.10 Schematic diagram of the partial structure of the locking assembly, the first supporting part and the second supporting part of the embodiment of the present application. Figure 7 and Fig. 9 Corresponding to the locked state of the locking assembly 305, Figure 8 and Fig.10 Corresponding to the unlocked state of the locking assembly 305. In some embodiments, as Figure 7 and Fig. 9As shown, the locking assembly 305 includes a blocking member 3051. When the locking assembly 305 is in a locked state, the blocking member 3051 extends to the movement path of the first supporting portion 3031 or the second supporting portion 3032. Thus, the first supporting portion 3031 or the second supporting portion 3032 can be blocked from moving along the movement path, so that the lifting platform 300 can be locked.

[0083] In some embodiments, Figure 8 and Fig.10 As shown, when the locking assembly 305 is in the unlocked state, the blocking member 3051 ( Figure 8 ) is located outside the movement path of the first support portion 3031 and the second support portion 3032. Thus, the first support portion 3031 and the second support portion 3032 can move along the movement path, thereby unlocking the lifting platform 300.

[0084] In some embodiments, Figures 7 to 10 As shown, the blocking member 3051 can be disposed on the arm of the first supporting portion 3031 of the supporting assembly 303. By disposing the blocking member 3051 on the outer first supporting portion 3031, it is convenient for the user to connect or separate the locking state switching assembly 306 and the locking assembly 305. The present application is not limited thereto, and the blocking member 3051 can also be disposed on the arm of the second supporting portion 3032.

[0085] In some embodiments, Fig. 9 As shown, when the locking assembly 305 is in the locked state, the second end 3051 b of the blocking member 3051 may be located at a position protruding inward from the first supporting portion 3031 so as to be located on the movement path of the second supporting portion 3032 .

[0086] like Fig.10 As shown, when the locking assembly 305 is in the unlocked state, the second end 3051b (not shown) of the blocking member 3051 may be located at a position not protruding inward from the first supporting portion 3031, for example, the blocking member 3051 may be located at a position where the second end 3051b is flush with the inner side surface of the first supporting portion 3031. Thus, the movement of the second supporting portion 3032 can be avoided from being hindered.

[0087] In some embodiments, there may be a plurality of blocking members 3051, and the plurality of blocking members 3051 may be respectively disposed on the two arms of the first supporting portion 3031. Thus, the plurality of blocking members 3051 can not only block the first arm 3031a of the first supporting portion 3031 and the first arm 3032a of the second supporting portion 3032 from rotating around the axis 3033, but can also block the second arm 3031b of the first supporting portion 3031 and the second arm 3032b of the second supporting portion 3032 from rotating around the axis 3033, thereby more reliably preventing the support assembly 303 from moving.

[0088] In some embodiments, the locking assembly 305 may also include other components. Figure 7 and Figure 8 As shown, the locking assembly 305 may further include a housing. The housing may include a first housing 3052 and a second housing 3053. The first housing 3052 is fixedly connected to the first supporting portion 3031, and the blocking member 3051 is movably mounted on the first housing 3052. The second housing 3053 is connected to a first end 3051a of the blocking member 3051 away from the supporting assembly 303, and the blocking member 3051 can drive the second housing 3053 to move in a direction away from or close to the first supporting portion 3031 (e.g., horizontal direction).

[0089] In some embodiments, the first shell 3052 can be fixedly connected to the first support portion 3031 in various ways. For example, a through hole is provided at a preset position of the first support portion 3031, one end of the first shell 3052 can be provided in the through hole, and one end of the first shell 3052 is fixed in the through hole of the first support portion 3031 by a nut provided on the outer circumference of the first shell 3052; for another example, matching threads can be provided on the inner wall of the through hole and the outer circumference of the first shell 3052, and one end of the first shell 3052 is fixed in the through hole by threaded connection; for another example, the first support portion 3031 can be fixed in the through hole by bonding, welding, riveting, etc.

[0090] In some embodiments, the second housing 3052 can be connected to the first end 3051a of the blocking member 3051 in various ways. For example, the connection between the second housing 3052 and the first end 3051a of the blocking member 3051 can be similar to the connection between the first housing 3052 and the first support portion 3031 described above.

[0091] In some embodiments, Figure 7 and Figure 8 As shown, in a state where one end of the first housing 3052 is fixedly connected to the first support portion 3031, the other end of the first housing 3052 protrudes outward from the first support portion 3031. The second housing 3053 is also disposed outside the first support portion 3031. Thus, even if the interval between the first support portion 3031 and the second support portion 3032 is small, the blocking member 3051 can be disposed on the support assembly 303; and it is convenient to separate or connect the locking state switching assembly 306 and the locking assembly 305.

[0092] In some embodiments, Figure 7As shown, when the locking state switching assembly 306 is separated from the locking assembly 305, the second housing 3053 abuts against the first supporting portion 3031, and the first housing 3052 is contained in the second housing 3053. Since the blocking member 3051 blocks the movement of the second supporting member 3032 in the locked state, a large force is applied to the blocking member 3051. By making the second housing 3053 abut against the first supporting portion 3031, the displacement of the locking assembly 305 can be avoided, thereby reliably preventing the movement of the second supporting member 3032. In addition, when the locking assembly 305 is in the locked state, by making the first housing 3052 contained in the second housing 3053, the first housing 3052 can be avoided from being subjected to an external force and unexpected displacement, thereby further improving the reliability of the locking.

[0093] In some embodiments, Figure 8 As shown, when the locking state switching assembly 306 is connected to the locking assembly 305, a portion of the locking state switching assembly 306 is located between the second housing 3053 and the first supporting portion 3031. Driven by the second housing 3053, the second end 3051b of the blocking member 3051 is received in the first housing 3052.

[0094] In some embodiments, a portion of the locking state switching assembly 306 (e.g., the aforementioned claw portion 3062) is engaged with the second housing 3053 and the first supporting portion 3031, wherein the width of the portion may be equal to the length of the second end 3051b of the blocking member 3051 protruding inward from the first supporting portion 3031 in the locked state. By setting the width of the portion to an appropriate value, the second end 3051b of the blocking member 3051 can be located at a position that blocks the movement of the second supporting portion 3032. The present application is not limited thereto, and the width of the portion may also be greater than the length of the second end 3051b of the blocking member 3051 protruding inward from the first supporting portion 3031 in the locked state.

[0095] The present application is not limited thereto, and in some embodiments, when the locking state switching assembly 306 is separated from the locking assembly 305, the second housing 3053 may abut against the first housing 3052. For example, the second housing 3053 abuts against the first housing 3052 in the horizontal direction. Alternatively, in some embodiments, when the locking state switching assembly 306 is connected to the locking assembly 305, a portion of the locking state switching assembly 306 may be located between the second housing 3053 and the first housing 3052.

[0096] In some embodiments, in order to enable the blocking member 3051 to reliably protrude from the first supporting portion 3031 toward the second supporting portion 3032, an elastic component may be provided in the locking assembly 305. The elastic component may be located between the first housing 3052 and the blocking member 3051, and apply a force to the blocking member 3051 to move the blocking member 3051 toward the second supporting portion 3032.

[0097] like Figure 7 and Figure 8 As shown, the elastic component 3054 may be disposed on the outer peripheral side of the blocking member 3051. For example, the elastic component 3054 is accommodated in the first housing 3052, one end of the elastic component 3054 abuts against the first housing 3052, and the other end abuts against the blocking member 3051.

[0098] Thus, when the locking state switching assembly 306 is connected to the locking assembly 305, the second end 3051b of the blocking member 3051 is received in the first housing 3052, and the elastic member 3054 is in a first compressed state; after the locking state switching assembly 306 is separated from the locking assembly 305, the second end 3051b of the blocking member 3051 protrudes from the first housing 3052 under the action of the elastic member 3054, and the elastic member 3054 is in a natural state or a second compressed state, wherein the compression degree of the second compressed state is lower than that of the first compressed state. The present application is not limited thereto, and the elastic member 3054 can be disposed on the inner side of the blocking member 3051.

[0099] In some embodiments, Figures 7 to 10 As shown, the locking assembly 305 may further include a force applying portion 3055. The force applying portion 3055 is connected to the second housing 3053. By providing the force applying portion 3055, it is convenient for the user to apply a force in a direction away from the supporting assembly 303 to the second housing 3053, thereby facilitating the user to place the locking state switching assembly 306 between the second housing 3053 and the first supporting portion 3031 or between the second housing 3053 and the first housing 3052.

[0100] The present application is not limited thereto, and the locking assembly 305 may also be other structures. For example, the locking assembly 305 may not be provided with the aforementioned second housing 3053. For example, the first end 3051a of the blocking member 3051 away from the supporting assembly 303 may include an abutment portion. When the locking state switching assembly 306 is connected to the locking assembly 305, a part of the locking state switching assembly 306 is located between the abutment portion and the first supporting portion 3031, or a part of the locking state switching assembly 306 is located between the abutment portion 306 and the first housing 3052.

[0101] When the lock state switching assembly 306 is separated from the lock assembly 305 , the abutment portion may abut against the first shell 3052 .

[0102] In some embodiments, the outer diameter of the abutment portion may be larger than the outer diameter of the middle portion between the first end 3051a and the second end 3051b of the blocking member 3051. The present application is not limited thereto, and the abutment portion may be other structures as long as it can abut against a portion of the locking state switching assembly 306.

[0103] The present application is not limited thereto, and the locking assembly 305 may also not include an elastic component. For example, when the locking state switching assembly 306 is separated from the locking assembly 305, the second housing 3053 may abut against the first supporting portion 3031 or the first housing 3052 through magnetic attraction.

[0104] It is worth noting that the above only describes the components or modules related to this embodiment, but the present application is not limited thereto. The lifting platform may also include other components or modules, and the specific contents of these components or modules may refer to the relevant technology.

[0105] According to the above embodiment, a locking component capable of locking the movement of the supporting component of the lifting platform, and a locking state switching component detachably connected to the locking component are provided in the lifting platform. When the locking state switching component is connected to the locking component, the locking component is in an unlocked state, and the supporting component can move freely; when the locking state switching component is separated from the locking component, the locking component is in a locked state, and the movement of the supporting component is blocked. In other words, by separating the locking state switching component from the locking component, the locking component can be switched from an unlocked state to a locked state to lock the lifting platform. Thus, the locking operation can be simplified, which helps to avoid safety problems. In addition, by connecting the locking state switching component to the locking component, the locking component can be switched from a locked state to an unlocked state to unlock the lifting platform. Thus, it helps to avoid unlocking the lifting platform due to misoperation, which helps to avoid safety problems.

[0106] The present application also provides a medical device. The medical device includes the lifting platform as described above. Figure 1 As shown, the medical device may be a CT system 100 or the like.

[0107] According to the above embodiment, a locking component capable of locking the movement of the supporting component of the lifting platform, and a locking state switching component detachably connected to the locking component are provided in the lifting platform. When the locking state switching component is connected to the locking component, the locking component is in an unlocked state, and the supporting component can move freely; when the locking state switching component is separated from the locking component, the locking component is in a locked state, and the movement of the supporting component is blocked. That is to say, by separating the locking state switching component from the locking component, the locking component can be switched from an unlocked state to a locked state to lock the lifting platform. Thus, the locking operation can be simplified, which helps to avoid safety problems. In addition, by connecting the locking state switching component to the locking component, the locking component is switched from a locked state to an unlocked state to unlock the lifting platform. Thus, it helps to avoid unlocking the lifting platform due to misoperation, which helps to avoid safety problems. By providing the lifting platform in the medical device, the locking operation can be simplified during the operation of the medical device, and it helps to avoid safety problems caused by misoperation.
