Description

Technical Field

[0001] This application relates to the field of auxiliary installation of medical testing equipment, and more specifically, to an installation and positioning fixture for medical testing equipment. Background Technology

[0002] Medical testing equipment, such as PET, PET-CT, CT, and MRI, is typically installed in a specific space, such as an examination room or laboratory. There are specific requirements for the installation location and precision. Furthermore, these devices are relatively heavy and large, making them difficult to move. Therefore, before installation, it is necessary to determine the outline of the installation location based on the size of the equipment to avoid having to move the equipment after installation is complete.

[0003] In existing technologies, paper or metal templates of the same size as the equipment are generally used for positioning. Paper templates are usually stacked and unfolded to form the projection of the equipment's mounting surface. Metal templates are typically composed of multiple small metal pieces pieced together to form the projection of the equipment's mounting surface. Positioning holes are pre-drilled in both paper and metal templates. Paper templates are lightweight but have poor positioning accuracy, while metal templates are bulky but have higher positioning accuracy. However, due to the different sizes of different types and models of equipment, each type and model requires a separate paper or metal template, making them incompatible. Furthermore, both paper and metal templates represent the projection of the equipment's mounting surface, which is the surface in contact with the ground. However, due to the limitations of the equipment's structure, the projected shape of the template generally does not match the size of the mounting surface. Positioning requires calculation based on the shape, necessitating manual measurement and calculation to determine the position of the shape when using paper or metal templates. This significantly increases the difficulty and workload of installation.

[0004] The background art description is provided solely for the purpose of understanding the relevant technologies in this field and is not intended as an admission of prior art. Summary of the Invention

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] As described in the background section, existing technologies using paper and metal templates for positioning fixtures suffer from incompatibility issues between different types and models of equipment, requiring each model of every type of equipment to be equipped with a corresponding template. Furthermore, since paper and metal templates mark the mounting surface rather than the equipment's outline, manual measurement and calculation are still necessary during positioning, compromising both accuracy and efficiency.

[0038] To address the aforementioned issues, this application provides an installation and positioning fixture for medical testing equipment. This fixture is adaptable to different types and models of equipment and requires virtually no manual measurement or calculation, greatly improving the accuracy, compatibility, and convenience of fixture installation.

[0039] The following description, with reference to the accompanying drawings, illustrates some preferred embodiments of the present application. It should be noted that the following description is for illustrative purposes only and is not intended to limit the scope of protection of this application.

[0040] Figure 1 This is a schematic diagram of the installation and positioning fixture for a medical testing device according to an embodiment of this application. Figure 1 As shown, the installation and positioning fixture for the medical testing equipment provided in this application generally includes: a controller 100 and a projection component 200.

[0041] Specifically, the controller 100 is used to generate control commands based on the information of the medical testing equipment to be installed. In one example, the information of the medical testing equipment to be installed includes shape parameters and positioning hole parameters. The shape parameters include the shape parameters of the examination bed and the shape parameters of the medical testing equipment itself. The positioning hole parameters include the positioning hole parameters of the examination bed and the shape parameters of the medical testing equipment. When the medical testing equipment to be installed is PET-CT, the shape parameters include the shape parameters of PET and CT, and the positioning hole parameters include the positioning hole parameters of PET and CT. When the medical testing equipment to be installed is PET-MR, the shape parameters include the shape parameters of PET and MR, and the positioning hole parameters include the positioning hole parameters of PET and MR. When the medical testing equipment to be installed is PET-proton therapy, the shape parameters include the shape parameters of PET and proton therapy, and the positioning hole parameters include the positioning hole parameters of PET and proton therapy. In other words, when a medical testing device includes one, two, or more different imaging devices, the shape parameters and positioning hole parameters of the medical testing device all include the shape parameters and positioning hole parameters of the different imaging devices. These shape parameters and positioning hole parameters have actually been calculated according to the ideal alignment state of the different devices. In another example, the information of the medical testing device to be installed conforms to the models of different devices to be installed, and the controller 100 analyzes the shape parameters and positioning hole parameters of the device to be installed based on the model of the device to be installed. Of course, it is understandable that the required information of the medical testing device to be installed is determined according to the installation steps of the device to be installed. For example, when the medical testing device to be installed is a complete machine transported to the installation location, no installation is required, only movement into place, so only the outline is needed. As another example, when the medical testing device to be installed is divided into a testing device and an examination bed and transported to the installation location, the testing device and the examination bed need to be assembled, so the relevant information of the testing device and the examination bed as described above is needed. As yet another example, when the medical testing device to be installed is transported to the installation location in smaller parts, the individual parts need to be assembled, so the relevant information of each part is needed.

[0042] Optionally, the controller 100 includes a control panel for receiving information from the medical testing equipment to be installed.

[0043] Optionally, the controller 100 can also receive information from the medical testing equipment to be installed via a mobile or fixed terminal.

[0044] Specifically, the projection component 200 is connected to the controller 100, and the projection component 200 is used to project the outline and / or positioning points of the medical testing device to be installed according to the control command, especially the outline of the medical testing device to be installed.

[0045] Figure 2 This is a first usage state diagram of the installation and positioning fixture for a medical testing device according to an embodiment of this application. Figure 3 This is a second usage state diagram of the installation and positioning fixture for a medical testing device according to an embodiment of this application. Figure 4 This is a diagram illustrating the usage effect of the installation and positioning fixture for a medical testing device according to an embodiment of this application. (Combined with...) Figures 2-4 To illustrate actual use, 001 in the diagram represents the light emitted by the projection component 200, 002 represents the position of the positioning hole, and 003 represents the auxiliary line, which is not shown in actual use but is shown here for distinction. Figure 2 and Figure 3 The angle varies depending on the length of the light rays. 004 represents the center of the equipment, which is also the center of the installation space; 005 represents the equipment to be installed; and 006 represents the wall cross-section. In actual operation, the information of the equipment to be installed is first provided to the controller 100. Then, the controller 100 generates control commands based on the information of the equipment to be installed. The control commands indicate the projection size of the projection device and the position of the positioning holes. Based on the projected outline and the position of the positioning holes, the corresponding components only need to be installed in the corresponding positions. Generally, taking PET-CT as an example, it is usually transported to the installation position in four parts: the examination table, the CT detector, the PET detector, and the housing. During positioning, the outline projection and positioning holes of the entire PET-CT equipment, the outline projection and positioning holes of the examination table, the outline projection and positioning holes of the CT detector, and the outline projection and positioning holes of the PET detector need to be located sequentially. Installation is then carried out one by one based on these outline projections and positioning holes.

[0046] In addition to projecting the outline of the equipment to be installed (such as...) Figure 4 The outline formed by 001) and the position of the positioning holes (e.g. Figure 3 In addition to (002), the installation positioning fixture can also be used to determine the distance and angle between the projection of the equipment to be installed and the cross-sections 006 of the surrounding walls, thereby enabling the equipment to be installed in a predetermined position. For example, if the equipment to be installed needs to be placed in the center of the laboratory floor, the laboratory floor is square, and the axis of the equipment to be installed is required to be parallel to one of the wall cross-sections, the installation positioning fixture can first be controlled to project the outline of the equipment to be installed, and then the installation positioning fixture can be moved to find the center position and parallel angle using the projected outline. Figure 4This demonstrates that the positioned contour ensures that the center projection of the equipment to be installed is centered on the mounting surface.

[0047] Figure 5 This is a disassembled schematic diagram of the projection component of the installation and positioning fixture for a medical testing device according to an embodiment of this application. Figure 6 This is a disassembly diagram of the laser emitting module of the installation and positioning fixture for a medical testing device according to an embodiment of this application. Figure 5 and Figure 6 As shown in one example of this application, the projection component 200 includes multiple sets of laser emitting modules 210. Each laser emitting module 210 includes a driving mechanism and a linear laser emitter 211. The driving mechanism adjusts the angle of the linear laser emitter 211 according to the control command, thereby adjusting the angle and length of the light emitted by the linear laser emitter 211. The driving mechanism can be a motor. The linear laser emitter 211 emits laser light according to the control command. The laser light emitted by the multiple sets of laser emitting modules 210 forms the projection of the device to be installed. In addition, the position of the positioning hole can be obtained by adjusting two linear laser emitters 211 according to the coordinates of the mounting hole so that the light rays emitted by the two intersect, and the intersection point is the position of the positioning hole.

[0048] Furthermore, in one example of this application, see also: Figure 6 Each of the laser emitting modules 210 includes a distance sensor 212, which measures the distance between the laser emitting module 210 and the ground, thereby facilitating the controller 100 to calculate the length of the light emitted by the linear laser emitter 211. Specifically, the distance between the laser emitting module 210 and the ground is measured by the distance sensor 212 and fed back to the controller 100. When the laser emitting module 210 is driven by a motor, the distance to the ground can be fed back to the motor, and then the laser emitting module 210 can be controlled to rotate to a corresponding angle, thereby adjusting the length of its light beam.

[0049] Generally, the number of laser emitting modules 210 is determined by the shape of the device to be installed, aiming to accurately depict the outline and positioning points of the medical testing equipment. For example, when the device to be installed is square, the number of laser emitting modules 210 is four; when the device to be installed is cross-shaped, the number of laser emitting modules 210 is eight. Generally, the longest and widest lengths of the outer shape are used to form the projection. For example, if the device to be installed is a CT scanner, the length of the outer shape is the sum of the axial length of the CT scanner and the length of the examination table, and the width of the outer shape is the radial width of the CT scanner, forming a rectangular projection, such as... Figure 4 The projection shown is a rectangular projection, which differs slightly from the description here. Figure 4The device shown is a PET-CT scanner.

[0050] Preferably, in one example of this application, see also: Figure 5 The projection component 200 includes a level 220, which is used to indicate the levelness of the installation positioning fixture. Generally, before positioning, it is necessary to ensure that the installation positioning fixture is level. The level 220 is used to assist in adjustment to keep the installation positioning fixture level.

[0051] For example, see [link to previous article] Figure 5 The level 220 is positioned at the center of the projection assembly 200.

[0052] Optionally, see [link to relevant documentation] Figure 6 Each of the laser emitting modules 210 includes a motor 213, the output shaft 214 of which is connected to the linear laser emitter 211 and the ranging sensor 212, thereby allowing the linear laser emitter 211 and the ranging sensor 212 to be adjusted according to the control command.

[0053] Optionally, see [link to relevant documentation] Figure 5 All the laser emitting modules 210 and the level 220 are connected to a base plate 230, and the base plate 230 is connected to the support arm 300. Figure 1 A top cover 240 is connected above the base plate 230, forming a space between the base plate 230 and the top cover 240 to accommodate all the laser emitting modules 210 and the level 220. The top cover 240 is a reddish-brown plastic part, which protects the linear laser emitter 211 and the ranging sensor 212 while allowing red laser light to pass through.

[0054] Optionally, see [link to relevant documentation] Figure 6 The motor 213 is connected to the base plate 230 via a bracket 215.

[0055] Preferably, see continue to see Figure 6 The laser emitter 211 and the ranging sensor 212 in the same group are arranged side by side and are connected to the output shaft 214 of the motor 213 after being stored in a box. The box is configured to have a cover plate 217 and a bottom connecting plate 216.

[0056] Preferably, in one example of this application, see also: Figure 1 The installation and positioning fixture also includes a support arm 300 and a bottom shell 400. The support arm 300 is connected between the bottom shell 400 and the projection component 200. The support arm 300 can support the projection component 200. The controller 100 is disposed inside the bottom shell 400.

[0057] Figure 7 This is another structural schematic diagram of the installation and positioning fixture for a medical testing device according to an embodiment of this application. Figure 7 As shown, in one example of this application, the support arm 300 is rotatably connected to the base shell 400 so that the support arm 300 has a retracted state. Figure 7 ) and usage status ( Figure 1 In the stored state, the support arm 300 is parallel to the bottom surface of the base shell 400. In the usage state, the support arm 300 is perpendicular to the bottom surface of the base shell 400. The support arm 300 can be fixed in the usage state by a pin. During use, the base shell 400 is generally placed on the ground or an object parallel to the ground. Furthermore, the support arm 300 and the projection component 200 are also rotatably connected. In the stored state, both the support arm 300 and the projection component 200 are stored within the base shell 400. In the usage state, the support arm 300 drives the projection component 200 to a vertical position. The cross-section of the projection component 200 is generally parallel to the ground. The base shell 400 allows for the storage of the support arm 300 and the projection component 200 in the stored state.

[0058] Further, see also Figure 1 The support arm 300 is provided with a handle 310 to facilitate the switching of the state of the support arm 300.

[0059] Optionally, in one example of this application, the support arm 300 is configured to be telescopic in its own length direction, thereby meeting the different height requirements of the projection component 200 in different scenarios.

[0060] Preferably, in one example of this application, see also: Figure 1 and Figure 7 The installation and positioning fixture also includes multiple support casters 600, and the connection between each support caster 600 and the base shell 400 is configured to be rotatable, so that the support caster 600 has a working state and a stored state. Figure 7 In use, the support casters 600 support the base shell 400, creating a gap between the base shell 400 and the ground. It is understood that the support casters 600 can move the entire installation and positioning fixture under external force. By providing a rotatable connection between the support casters 600 and the base shell 400, the support casters 600 can be retracted by rotation when moving to the working position, thereby improving the stability of the entire installation and positioning fixture during operation.

[0061] Furthermore, the bottom shell 400 is provided with a groove for accommodating the support caster 600, such as... Figure 7 The support caster 600 shown is placed in the groove so that it can be placed in the groove when in the storage state.

[0062] Preferably, in addition to its own rotation, the support caster 600 can rotate relative to the base shell 400 by 90° or 180°. Here, besides the aforementioned usage and storage states, the support caster 600 also has a ready state. Figure 1 For example, when switching from the storage state to the use state, the support caster 600 can rotate 180° continuously through the groove to reach the use state. During use, if the working position has been initially reached, it can be rotated 90° continuously from the use state to the ready state. Since the bottom shell 400 is already in contact with the ground in the ready state, the entire installation and positioning device has the same stability as in the storage state.

[0063] In addition, each of the support casters 600 is provided with a support base, and the projection component 200 can be leveled by rotating the support base.

[0064] Figure 8 This is a schematic diagram of the storage state of the installation and positioning fixture for a medical testing device according to an embodiment of this application. Figure 8 As shown, and in combination Figure 7 In one example of this application, the installation positioning fixture further includes a cover plate 500, which is movably connected to the bottom shell 400. When the support arm 300 and the support casters 600 are in the stored state, the installation positioning fixture can be stored by covering it with the cover plate 500, thereby facilitating transportation.

[0065] Optionally, see [link to relevant documentation] Figure 7 The cover plate 500 and the bottom shell 400 are connected by a snap fastener 510.

[0066] It is understood that the installation and positioning fixture inevitably has some wiring harnesses; preferably, see below. Figure 1 The installation and positioning fixture also includes a cable reel box 900, which is set on the bottom shell 400 to facilitate cable storage.

[0067] Specifically, in one example of this application, see further... Figure 1 and Figure 7The mounting and positioning fixture also includes a battery 700 and a driver 800. The battery 700 supplies power to the controller 100, the projection component 200, and the driver 800. The driver 800 drives the projection component 200, which can be achieved by first driving a motor, which then directly drives the projection component 200. Both the battery 700 and the driver 800 are housed within the base housing 400. It is understood that in embodiments where the battery 700 can be replaced, power can also be supplied via an external power source.

[0068] The medical testing equipment installation and positioning fixture provided in this application, through the configuration of controller 100 and projection component 200, achieves compatibility of installation and positioning fixture with different types and models of equipment. Moreover, the projection formed is not limited to the installation surface, but can be the installation surface, the shape of the equipment, or a certain component. Through the switching of structural states, the size of the installation and positioning fixture is reduced and it is easy to transport, making operation simpler and improving efficiency.
