Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to an operating table. Background Art

[0002] The operating table and C-arm are one of the commonly used treatment instruments in the operating room. There is often a clinical scenario during the operation, that is, the medical staff pushes the C-arm into the operating table for fluoroscopy. At this time, the sterile sheet basically covers the entire operating table surface, and the position of the operating table and the patient's position relative to the operating table cannot be seen. When the medical staff pushes the C-arm into the operating table for fluoroscopy, the existing solution basically relies on vision and feeling. The medical staff cannot accurately judge the position of the operating table column. There is no indication and traction, which will inevitably lead to collision and damage to the column shield, and cause the operating table to shake, or the operator needs to lift the sterile sheet a little for observation, and then push the C-arm into the operating table. This operation process is cumbersome and easily causes surgical field contamination; both of the above situations have great safety risks.

[0003] Therefore, existing operating tables still need to be improved and enhanced. Summary of the invention

[0079] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0080] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0081] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0082] The operating table provided by the present invention projects light onto the ground, and simply and accurately points out prohibited areas related to one or some structural features of the operating table on the ground, thereby reducing the risk of structural features being hit when the operating table is used in conjunction with a C-arm machine, etc., and ensuring safe and efficient surgery. This will be described in detail below through some embodiments.

[0083] like Figure 1 and Figure 2 As shown, the operating table provided by the present invention includes a table top 1, a column 2 and a base 3.

[0084] The table top 1 is used to carry a patient. For example, a patient can lie on the table top 1 to facilitate surgery.

[0085] The column 2 is located between the table top 1 and the base 3, and is used to support the table top. The bottom of the column 2 is fixed to the base 3, and the top of the column 2 can be fixed to the table top 1. In some embodiments, the column 2 has a lifting mechanism for lifting the table top 1, so that the doctor can adjust the height of the table top 1.

[0086] The base 3 is used to support the column 2. The table top 1 is usually rectangular, and the base 3 can also be rectangular. The left and right sides of the table top 1 and the base 3 can both be long sides, that is, the left side of the operating bed is the long side of the table top 1 and the long side of the base 3, and the right side of the operating bed is the other long side of the table top 1 and the other long side of the base 3. Such a setting is conducive to the stability of the entire operating bed and saves space.

[0087] The operating table further includes at least one light indicator. The light indicator can be arranged at any position of the operating table, for example, on the base 3 or on the column 2. Figure 3 As shown, the light indication device includes a projection device 4. The projection device 4 can also be set at any position of the operating bed, for example, it can be set on the base 3 or on the column 2. The projection device 4 is used to project a projection area A on the ground. The projection area is used to mark the prohibited area related to the structural features of the operating bed. The structural feature is a certain structure or certain structures of the operating bed, for example, the structural feature is the column 2 or the crossbeam at the bottom of the table. The crossbeam at the bottom of the table is connected to the top of the column 2 through a slide rail, so that the table 1 can slide relative to the column 2 through the slide rail to adjust the patient's position. The slide rail can be a slide rail that supports unidirectional sliding, or a slide rail that supports sliding in two different directions of X and Y (supporting the table 1 to slide on a horizontal plane). The prohibited area can be an area where people or objects (such as a C-arm machine) are prohibited from entering to ensure that the corresponding structural features will not be collided. It can be seen that the projection area A is equivalent to the position used to mark the structural features of the operating bed. The user knows the position of the structural feature when he sees the projection area A on the ground.

[0088] In this embodiment, the structural features are features related to the column 2, such as the column 2 itself or the beam at the bottom of the table. Of course, they can also be other features that can indirectly locate the column 2, so that the projection area A can mark the prohibited area related to the column 2. For example, the projection area A is used to mark the position of the column 2. In this way, even if the sterile sheet covers most or even all of the area of ​​the operating bed, the doctor can know the position of the column 2 through the projection area A, so that the column 2 will not be hit when the C-arm machine is pushed into the operating bed for fluoroscopy. For another example, the projection area A can also be used to mark the position of the beam at the bottom of the table. The user knows the position of the beam at the bottom of the table when he sees the projection area A on the ground. The position of the beam is actually related to the column 2, and the position of the column 2 can be indirectly determined, so that the column 2 will not be hit when the C-arm machine is pushed into the operating bed for fluoroscopy.

[0089] The projection area A can be in various shapes, such as square, triangle, circle or oval, and of course other shapes are not listed here. The color of the projection area A can also be various colors, such as yellow, red, white or purple, and of course other colors are not listed here. The color of the projection area A can be different from the color of the ambient light, so as to prompt the user more conspicuously. The brightness of the projection area A can also be higher than the brightness of the ambient light, so as to prompt the user more conspicuously. The projection area A can also contain icons, text, etc., so as to prompt more information. In this embodiment, the projection area A is a rectangle, and the color is yellow, which is the most eye-catching.

[0090] The projection area A is located on one long side of the operating table, and its position corresponds to the position of the structural feature, and in this embodiment corresponds to the position of the column 2. Figure 4 As shown, in the top view of the operating table, the central axis (dashed line in the figure) of the projection (dashed area in the figure) of the structural features (such as the column 2 or the beam at the bottom of the table) on the ground in the height direction coincides with the central axis of the projection area A. In other words, when the doctor stands on the left or right side of the operating table and faces the operating table, the projection area A seen on the ground is directly in front of the structural features. In this way, the projection area A can well reflect the position of the structural features such as the column 2. Figure 5 As shown, along the long side of the operating bed, the length L1 of the projection area is in a preset ratio with the size of the structural feature located on the long side of the operating bed. Specifically in this embodiment, the length L1 of the projection area is in a preset ratio with the width W2 of the column.

[0091] If the projection device 4 is arranged on the base 3, it can be located on the long side of the base 3 and below the column 2, so that the position of the projection area 4 projected by the projection device 4 corresponds to the column 2 or the crossbeam at the bottom of the table. The operating table can have two projection devices 4, and the two projection devices 4 can be located on the two long sides of the base 3 respectively, so that the doctor can see a projection area 4 on the ground regardless of whether he is on the left or right side of the operating table. The projection device 4 is arranged on the base 3 to project the projection area on the ground more clearly.

[0092] If the projection device 4 is disposed on the column 2, it can be located on the left or right side of the column 2, that is, on the side of the column 2 close to the long side of the base, so that the position of the projection area 4 projected by the projection device 4 corresponds to the column 2 or the crossbeam at the bottom of the table. The operating table can have two projection devices 4, and the two projection devices 4 can be located on the left and right sides of the column 2 respectively, so that the doctor can see a projection area 4 on the ground regardless of whether he is on the left or right side of the operating table.

[0093] From the above content, it can be seen that the projection area A projected by the projection device 4 onto the ground corresponds to the position of the column 2 or the crossbeam at the bottom of the table, so that the C-arm operator can quickly identify the position of the column 2, thereby avoiding the situation where the C-arm operator enters the operating bed and collides with the column cover, causing damage to the operating bed column cover or the C-arm.

[0094] The length L1 of the projection area has a certain ratio with the dimension of the structural feature located on the long side of the operating table, i.e., a preset ratio. The preset ratio can be between 1:2 and 3:2. Taking the column as an example, the length L1 of the projection area can be between 0.5 and 1.5 times the width W2 of the column. In this embodiment, the preset ratio is 1:1, i.e., the length L1 of the projection area is equal to the width W2 of the column, which is convenient for accurately prompting the doctor the position and width of the column.

[0095] The projection area exceeds the projection of the structural feature on the ground along the height direction of the operating table, which is convenient for the user to observe. In this embodiment, the projection area A exceeds the projection of the base 3 on the ground along the height direction. Figure 3 Only a portion of the projection area A shown exceeds the projection of the base 3 on the ground in the height direction. Figure 4 The projection area A shown in the figure exceeds the projection of the base 3 on the ground in the height direction. The projection area A exceeds the projection of the base 3 on the ground in the height direction. Even if the sterile sheet falls to the ground, the doctor can at least see the edge of the projection area A, so he can still know the position and width of the column 2.

[0096] like Figure 6 and 7 As shown, the projection device 4 includes a light source mounting member 41 , a light-transmitting plate 43 having a first light-transmitting area, and a light source 42 mounted on the light source mounting member 41 .

[0097] The light source mounting member 41 is used to be mounted on the operating bed, so that the entire projection device is fixed on the operating bed. In this embodiment, the light source mounting member 41 is used to be mounted on the base 3, and the base 3 has a mounting groove 34 for accommodating the projection device 4. The projection device 4 can be embedded in the mounting groove 34 of the base 3 for easy disassembly and assembly. Specifically, the bottom of the light source mounting member 41 has at least two bosses 45. The mounting groove 34 of the base 3 has a positioning hole 32 adapted to the boss 45. The projection device 4 is installed in the mounting groove 34, and each boss 45 extends into the corresponding positioning hole 32 to position and limit the projection device 4. The bottom of the light source mounting member 41 fits with the bottom surface of the mounting groove 34, and the positioning method of two points (bosses) and one surface ensures that the projection device 4 is accurately installed, the installation structure is simple, and maintenance is convenient. The light source mounting member 41 can be fixed in the mounting groove 34 by its own weight, or by a threaded fastener. Since the bottom of the light source mounting member 41 is limited by two points and one surface, it is only necessary to apply a downward force to the light source mounting member 41 through a threaded fastener to fix the light source mounting member 41, so the disassembly and assembly of the projection device 4 is very convenient.

[0098] The light source 42 faces the light-transmitting plate 43. Figure 8 As shown, the light emitted by the light source 42 passes through the light-transmitting plate 43 and projects a projection area A on the ground. Figure 6 and Figure 8 The quadrangular pyramid F in the figure is a light cone formed by the light emitted by the point light source 42, and the projection area A has a projection of the first light-transmitting area. The first light-transmitting area in the light-transmitting plate 43 has a different light transmittance from other areas in the light-transmitting plate 43, and its light transmittance can be lower (even non-transmittance) or higher (even fully transmittance), so that the first light-transmitting area can be highlighted. Figure 8 The first light-transmitting area is the area with the word "mindray". The light transmittance of this area is lower or higher than the surrounding area, so that the darker or brighter "mindray" can be seen in the projection area A. Of course, the graphics of the first light-transmitting area can also be characters, patterns, etc. used as prompts. The light-transmitting plate 43 can be parallel to the ground for easy projection. The color of the first light-transmitting area can also be different from other areas in the light-transmitting plate 43, so that areas of different colors can be formed in the projection area A, which is both beautiful and eye-catching.

[0099] The light source mounting member 41 has a cavity 44 ( Figure 7 The light source 42 is in the cavity 44, and the light-transmitting plate 43 covers the exit of the cavity 44. The surface of the cavity 44 is rough to form diffuse reflection. In order to reduce the roughness of the surface of the cavity 44, the cavity 44 can be processed by etching, sandblasting, shot blasting, laser or painting, so that the surface of the cavity 44 forms diffuse reflection conditions, and the projected effect is clear without ghosting.

[0100] The light source 42 can be a point light source or a surface light source. If the light source 42 is a surface light source, the shape and size of the surface light source can be consistent with the light-transmitting plate 43, so that the light-transmitting plate 43 can be projected onto the ground at a ratio of 1:1 to form a projection area A. Considering that the width of the column 2 is relatively wide, this solution requires a surface light source and a light-transmitting plate 43 with a larger area. Therefore, in this embodiment, the light source 42 can be a point light source or a surface light source, but the light-emitting area of ​​the light source 42 is smaller than the light-transmitting plate 43, so that the light emitted by the light source 42 to the light-transmitting plate 43 is radial, such as Figure 8 As shown, the light passes through the light-transmitting plate 43 and is projected onto the ground to form a projection area A. The projection area A formed in this way is equivalent to enlarging the light-transmitting plate 43.

[0101] like Fig. 9 As shown, the light source 42 is located above the light-transmitting plate 43, and the emitted light is partially blocked and partially transparent by the light-transmitting plate 43, so that the desired content (such as the pattern on the light-transmitting plate) is projected on the ground. The magnification or reduction ratio of the projection area A compared to the light-transmitting plate 43 is set by controlling the distance h between the light source 42 and the light-transmitting plate 43, where H is the distance from the light source 42 to the ground. The magnification or reduction ratio is R=H:h. As long as the light-emitting area of ​​the light source 42 is smaller than that of the light-transmitting plate 43, then R is the magnification. In this embodiment, taking magnification as an example, the boundary length L1 of the projection area A is equal to the boundary length a of the light-transmitting plate 43 multiplied by the magnification R, and the boundary width W1 of the projection area A is equal to the boundary width b of the light-transmitting plate 43 multiplied by the magnification R. It can be seen that by setting the light penetration boundaries a and b of the light-transmitting plate 43 and setting the magnification R, the boundaries L1 and W1 of the projection area can be obtained.

[0102] Considering the height (thickness) of the base 3 and the required length of the projection area A, the ratio R between the vertical distance H from the light source 42 to the ground and the vertical distance h from the light source 42 to the light-transmitting plate 43 can be greater than or equal to 1:1 and less than or equal to 5:1. When R is in the ratio range of 1:1 to 5:1, the projection area is relatively clear.

[0103] Since the size of the projection area A is enlarged compared to the size of the light-transmitting plate 43, the light emitted by the projection device 4 to project the projection area A has an angle with the ground. Figure 3 As shown, the minimum angle a between the light emitted by the projection device 4 and the ground for projecting the projection area A is between 30° and 60°. When the minimum angle a is between 30° and 60°, the projection area A can be well reflected into the eyes of the operator, allowing the operator to observe the projection area A more easily and comfortably.

[0104] The long side of the base 3 is located on the long side of the operating table. Figure 6As shown, the long side of the base 3 has a convex edge 31. In this embodiment, the projection device 4 is arranged inside the base 3, and the light emitted by the projection device 4 is emitted from the bottom surface of the convex edge 31 to project a projection area on the ground. There are usually supporting legs or wheels under the base of the operating bed, so most of the bottom surface of the base is at a certain distance from the bottom surface, and the edge of the base is the convex edge 31. In this embodiment, the light cone F formed by the light emitted by the projection device 4 is below the convex edge 31, which makes it easy for users to see the projection area and hides the projection device 4 without changing the appearance of the base. This hidden design makes full use of the characteristics of the base and is beautiful and simple.

[0105] The operating bed may also include a first detection device for detecting the change in the distance between the operator and the operating bed. The first detection device may be matched with a corresponding projection device 4. The first detection device may include a camera or an infrared sensor, etc. The camera or infrared sensor faces the side (left or right) of the operating bed. The first detection device may identify a person from the video captured by the camera, and take the person closest to the outer area of ​​the operating bed as the operator, and determine whether the distance between the operator and the operating bed is increasing or decreasing by the change in the operator's image in the video. For example, if the image area of ​​the operator in the video is getting larger and larger, it means that the operator is walking towards the operating bed, and if the image area of ​​the operator is getting smaller and smaller, it means that the operator is away from the operating bed. Of course, the first detection device may also obtain the distance between the operator and the operating bed through image processing, and then the change in the distance between the operator and the operating bed can be known according to the distance at different times. For example, the camera may use a binocular camera, and the first detection device may identify the operator from the left video and the right video captured by the binocular camera, and then obtain the distance between the operator and the operating bed according to the parallax of the operator in the two videos. The infrared sensor may be set on the side of the operating bed. The first detection device can identify the operator from the data detected by the infrared sensor. For example, the person with the strongest signal is the operator closest to the operating bed, and thus determine whether the distance between the operator and the operating bed increases or decreases based on the change in the operator's signal strength. For example, if the operator's infrared signal strength becomes stronger and stronger, it means that the operator is walking towards the operating bed; if the operator's infrared signal strength becomes weaker and weaker, it means that the operator is moving away from the operating bed.

[0106] The projection device 4 can reduce the brightness of the projection area 4 when the distance between the operator and the operating table becomes smaller. Because the operator is getting closer to the operating table, the projection area does not need to be as bright as before, which can avoid interfering with the doctor's operation. When the distance between the operator and the operating table becomes larger, the projection device 4 increases the brightness of the projection area, so that the operator can always see the projection area, realizing adaptive column light prompts.

[0107] The operating table may also include a second detection device for detecting the distance between the external object and the structural feature. For example, the second detection device may include a camera, an infrared sensor, or a distance measuring sensor.

[0108] When the distance between the external object and the structural feature is less than or equal to a preset threshold, the projection device 4 can change the color and / or brightness of the projection area to indicate the risk of collision, or intermittently project the projection area to make the projection area appear to flash to indicate the risk of collision. The second detection device can be set on a column, a base or a table, and the preset threshold can be a preset minimum safe distance between the external object and the structural feature. Fig.11 As shown, when an external object such as a C-arm is too close to the column, the projection device 4 will change the display mode of the projection area, thereby effectively reminding the operator that there is a risk of hitting the column.

[0109] The projection device 4 can also increase the brightness of the projection area when the distance between the external object and the structural feature becomes smaller, and reduce the brightness of the projection area when the distance between the external object and the structural feature becomes larger. The change in the distance between the external object and the structural feature is reflected by the change in the brightness of the projection area. With the distance reminder, the operator can avoid the C-arm machine from hitting the structural feature (such as a column).

[0110] Of course, in some embodiments, the operating table may also include a prompting device, using a separate prompting device to provide risk warning (alarm). The prompting device is used to issue a prompting message for indicating the risk of collision when the distance between the external object and the structural feature is less than or equal to a preset threshold. The prompting device issues a prompting message for indicating the risk of collision, which may be displayed on a display screen, or may issue a voice for indicating the risk of collision, or may be an indicator light that changes color or flashes, etc.

[0111] External objects also include operators, so the second detection device and the first detection device can be the same detection device. Of course, the second detection device can also be different from the first detection device.

[0112] like Fig.10As shown, the light indication device may further include one or more light-emitting bodies 5. The light-emitting body 5 can emit light, or can reflect light. In the present embodiment, one or more light-emitting bodies 5 are used to mark the position of the column by the light emitted by themselves. The light-emitting body 5 may be arranged on the column 2, so as to indicate the position of the column 2. For example, the column includes a protective cover, and the light-emitting body 5 is fixed inside the protective cover. The protective cover is transparent or translucent, or has holes for light to pass through. The light emitted by the light-emitting body 5 can mark the position of the column 2 after coming out of the protective cover. The light-emitting body 5 may also be fixed outside the protective cover, which is more eye-catching. Specifically, the light-emitting body 5 may be arranged on both the left and right sides of the side of the column 2 to mark the boundary of the side of the column. The light-emitting body 5 may be a light strip or a reflective strip, etc. The light-emitting body 5 may also be arranged on the base 3 and located below the column 2, such as Fig.10 The light-emitting body 5 at the bottom shown. The light-emitting body 5 can be specifically arranged on the base 3 and located directly below the column 2. Directly below means that the light-emitting body 5 is below the column 2, and the vertical center axis of the light-emitting body 5 is on the same line as the vertical center axis of the column 2. The length of the light-emitting body 5 at this position can be basically the same as the width W2 of the side of the column, which can not only well indicate the position of the column, but also accurately mark the width range of the column, greatly reducing the risk of the column being hit. The light-emitting body 5 can also be arranged on the table and located above the column. Similarly, the light-emitting body 5 can be specifically arranged on the table and located directly above the column. Directly above means that the light-emitting body 5 is above the column, and the vertical center axis of the light-emitting body 5 is on the same line as the vertical center axis of the column 2. The length of the light-emitting body 5 at this position can be basically the same as the width W2 of the side of the column, which can not only well indicate the position of the column, but also accurately mark the width range of the column.

[0113] The light emitting body 5 can also be controlled to emit light like a projection device. Specifically, in one embodiment, when the distance between the operator and the operating table becomes smaller, the light emitting body 5 reduces its brightness; when the distance between the operator and the operating table becomes larger, the light emitting body 5 increases its brightness.

[0114] In some embodiments, when the distance between an external object and a structural feature (such as a column) is less than or equal to a preset threshold, the light-emitting body 5 may also change the color and / or brightness of its own light to indicate the risk of collision, or may flash to indicate the risk of collision.

[0115] In other embodiments, when the distance between the external object and the structural feature becomes smaller, the light-emitting body 5 can increase the brightness of its own light; when the distance between the external object and the structural feature becomes larger, the light-emitting body 5 can reduce the brightness of its own light.

[0116] In this embodiment, the light emitting body 5 is used in conjunction with the projection device 4 to provide comprehensive light prompts. In some embodiments, the light indicating device may only include the light emitting body 5 without the projection device 4. The light emitting body 5 alone can also clearly indicate the position of the column, thereby avoiding collision.

[0117] In summary, during the operation, the sterile sheet basically completely blocks the operating tabletop, and the position of the operating table and the patient's position relative to the operating table cannot be seen. At the same time, during the operation, it may be necessary to push the C-arm machine into the operating table for perspective. The existing scheme basically relies on vision and feel to push the C-arm machine in, which can easily cause the C-arm machine to hit the column and damage the column cover, and also cause the operating table to shake. The operating table provided by the present invention can clearly indicate the position of the column cover through the above-mentioned light indication scheme, thereby displaying the position of the patient and the operating table and guiding the C-arm machine to interact with the operating table; so that the C-arm machine will not collide with the operating table during the operation; it has clinical value advantages. The light projected on the ground is simple and reliable, and has the advantage of ease of use. The projection device is concealedly installed inside the base, and the required installation space is small, which can meet the needs of cleaning and disinfection.
