[0052] Embodiment one

[0053] The present application provides a biosafety dissection table, comprising: an operation area 1 and a filter 9, the operation area 1 and the filter 9 are connected through an exhaust duct.

[0054] Wherein, the operation area 1 has a length direction and a width direction, and a first placement table 6, a cleaning table 4 are sequentially arranged along the length direction, the first placement table 6 can reciprocally slide within a specific sliding distance along the length direction; and a second placement table 7 is arranged along the width direction at the position adjacent to the cleaning table 4 of the operation area 1, so that the first placement table 6, the cleaning table 4 and the second placement table 7 jointly form an L-shaped operation route with adjustable size.

[0055] The operation area 1 comprises a baffle 2, a dissection table 3 and a bottom plate 8, edges of the dissection table 3 and the bottom plate 8 are connected to the baffle 2 with a certain height, or in other words, the baffle 2 has a certain height, the edges of the dissection table 3 and the bottom plate 8 are connected to the second end of the inner surface 21 of the baffle 2 and the second end of the outer surface 22 of the baffle 2 respectively, and the height of the outer surface 22 of the baffle is greater than that of the inner surface, so that the inside of the dissection table 3, the baffle 2 and the bottom plate 8 form a ventilation layer, the inner surface of the baffle 2 and the outer surface of the dissection table 3 together form an operation space with a certain height; and the ventilation layer is connected with the exhaust duct; the first end of the baffle 2 is provided with a first air inlet hole 23, and the edge of the dissection table 3 is provided with a second air inlet hole 31, the first air inlet hole 23 and the second air inlet hole 31 cooperate to guide the aerosol generated in the operation space during dissection into the ventilation layer.

[0056] Preferably, the first end of the baffle 2 forms a guide track, and the first placement table 6 has a mating track matched with the guide track, so that the first placement table 6 is slidably arranged at the first end of the baffle 2; the cleaning table 4 is arranged on the baffle 2 and / or the bottom plate 8, and the second placement table 7 is fixedly arranged on the outer surface of the baffle 2.

[0057] Preferably, a pulley is arranged below the operation area 1 to facilitate movement according to the needs of dissection, which can be flexibly applied to various dissection scenes.

[0058] Preferably, the height of the baffle 2 can be adjusted according to different practical needs. In some embodiments, in order to facilitate the operation of the user, the height of the baffle 2 can be flexibly designed according to the height range and arm length range of the user. In another embodiment, in order to facilitate the dissection operation of the user, the height of the baffle can be set as high as possible, so that the high-risk biological organisms are as far away from the user as possible, thereby reducing the risk of inhalation infection of the user.

[0059] The cleaning table 4 comprises a water tank and a faucet arranged on one side of the water tank. The end face of the water tank towards the faucet is lower than the height of the first air inlet hole.

[0060] The second placement table 7 is provided with a third air inlet hole 71 around the periphery, and the second placement table 7 is in communication with the ventilation layer.

[0061] A water-air separation device is installed on the base plate 8. This device is connected to the filter 9 via the exhaust duct, allowing aerosols in the ventilation layer to pass through the water-air separation device into the exhaust duct and be effectively purified in the filter 9, reducing harm to the user. Furthermore, the water-air separation device is also equipped with a filter screen to filter hair and other debris generated during dissection. Specifically, the filter screen can be made of stainless steel.

[0062] The filter 9 is a high-efficiency filter, also known as a bibo-filter. Furthermore, the filter 9 can be installed at the bottom of the operating area, which can effectively filter contaminants in the generated aerosols when dissecting highly pathogenic organisms.

[0063] The biosafety dissection table also includes a fan, which is located inside the exhaust duct. By activating the fan, aerosols in the operating space are guided into the ventilation layer by the cooperation of the first intake port 23 and the second intake port 31. At the same time, aerosols on the second placement table enter the ventilation layer through the third intake port 71. The aerosols are then transported to the high-efficiency filter 9 through the exhaust duct for absorption, filtration and purification, thereby improving the safety of the indoor environment in the dissection room.

[0064] Furthermore, this application also verified the filtration efficiency in the ventilation layer through simulation experiments, and the results are as follows: Figures 12-17 As shown. During the simulation experiment, the basic operating conditions were set as follows: during operation, the gas can be considered incompressible; the fan exhaust efficiency is 3500 m³ / s. 3 / s; The worktable sunk 30 cm. Using ANSYS Fluent 2020R1 tools, Realize... Mathematical models are used for numerical simulation. Figure 17 The diagram shows the gas flow direction in the longitudinal (a) and transverse (b) sections of the ventilation layer. Arrows indicate the airflow direction, and color represents the gas velocity. Under the action of the fan, a low-pressure zone is formed within the exhaust duct, and the airflow throughout the ventilation layer flows towards the exhaust duct. Numerical simulation results show that, under the set operating conditions, during use, aerosols enter the ventilation layer, form a directional flow with the airflow, and are discharged through the exhaust duct. Clearly, from... Figures 12-16 As can be seen, by combining the upper and lower air intake holes with the baffle, the aerosols in the operating space can be quickly guided into the ventilation layer, thereby greatly reducing the outward spread of highly pathogenic microorganisms such as viruses and bacteria, and thus improving the protection level.

[0065] Due to the first suction hole 23 and the second suction hole 31 in the operation space where the dissection table 3 is located, and the third suction hole 71 in the second placement table 7, the operation area is indirectly divided into different protection levels, and the dissection table 3 can be a first dangerous area, and the second placement table 7 can be a second dangerous area.

[0066] In some embodiments, the biosafety dissection table is particularly suitable for dissecting highly pathogenic organisms, wherein the dissection table 3 can place high-risk samples such as animals infected with pathogenic microorganisms, and the second placement table 7 can place low-risk samples such as non-pathogenic tissues or organs removed during dissection.

[0067] The biosafety dissection table further comprises a lighting device 5, which is arranged adjacent to the cleaning table 4, and the lighting device 5 comprises a first lighting lamp 51 and a second lighting lamp 52 capable of adjusting the lighting area. Specifically, the light source provided by the first lighting lamp 51 can cover the second placement table 7 and the cleaning table 4 arranged along the width direction; and the light source provided by the second lighting lamp 52 can cover the first placement table 6 and the operation space arranged along the length direction. With the assistance of the first lighting lamp 51 and the second lighting lamp 52, the user can more conveniently perform dissection operations and further observe the samples. For example, the lighting lamp can be a shadowless lamp.

[0068] In some embodiments, the first lighting lamp 51 can be fixedly arranged on one side close to the cleaning table 4, and the lighting area of the second lighting lamp 52 can be adjusted, and the light source thereof can cover the entire operation space and the first placement table 6, so as to reduce the number of times of adjusting the light by the user during dissection and reduce the risk of the user being infected.

[0069] Alternatively, in other embodiments, three or more lighting lamps can be arranged.

[0070] The biosafety dissection table further comprises at least one limiting component 24, which is arranged on the first end of the baffle 2, and the limiting component 24 is used for limiting the sliding distance of the first placement table 6. Specifically, the limiting component 24 is provided with a first clamping position, and the first end of the baffle 2 or the guide rail is provided with a second clamping position matched with the first clamping position, so that the limiting component 24 can be detachably arranged on the baffle 2 or the guide rail; or the limiting component 24 has magnetism, so that it can be attached to the baffle 2 by magnetic force. Further, the arrangement position of the limiting component can be determined according to the actual dissection needs of the user, so as to facilitate the user to perform dissection operations.

[0071] In some embodiments, when a large number of samples need to be dissected, the limiting component 24 can be arranged on the side of the baffle 2 away from the cleaning table 4, at this time the first placement table 6 is limited at the end of the baffle 2 away from the cleaning table 4, so that there is enough space to place the samples, and the user is close to the cleaning table 4, which is more convenient for cleaning the samples during the dissection process.

[0072] In other embodiments, when the number of samples is small, the limiting component 24 can be arranged in the middle of the baffle 2, at this time the first placement table 6 is limited in the middle of the baffle 2, and the user is close to the cleaning table 4, which can reduce the time for the user to walk back and forth, and is beneficial to improve the dissection efficiency of the user.

[0073] In some embodiments, the first placement table 6 is provided with at least two layers of equipment plates in the height direction.

[0074] In some embodiments, the first placement table 6 can be an instrument placement table for placing instruments used in dissection, such as trays, surgical blades, hemostatic forceps, surgical scissors, ophthalmic forceps, tissue forceps, etc.

[0075] The biosafety dissection table further comprises a display panel, and a camera, a control system and a pedal associated with the display panel. The display panel has high resolution and can present details in the dissection process to facilitate more accurate dissection by the user; the pedal has a certain height so that the user can stand on the pedal to facilitate dissection.

[0076] In other embodiments, the dissection table can also not be provided with a second placement table, such as a straight-line type dissection table.

[0077] The biosafety dissection table of the present application is particularly suitable for dissection of highly pathogenic organisms, and has the beneficial technical effects that: on the one hand, the slidable first placement table and the limiting component cooperate to form an L-shaped operation route with adjustable size by the first placement table, the cleaning table and the second placement table, so that a suitable L-shaped operation route can be set according to the actual dissection requirements to improve the dissection efficiency; on the other hand, the baffle with a certain height enables the first air inlet and the second air inlet to better cooperate to guide the aerosol generated in the operation space to enter the ventilation layer under the action of the fan, and then be transported to the high-efficiency filter through the exhaust duct for effective purification, in addition, the third air inlet arranged on the second placement table is also beneficial to collect the aerosol, and the three air inlets effectively prevent the diffusion of the aerosol to improve the safety of the environment in the dissection room, reduce the risk of inhalation infection of the user, and reduce the harm to the user.

[0078] It is worth mentioning that the biosafety dissecting table in the present application can be applied to dry dissecting environment, and can also be applied to wet dissecting environment. For example, when the biosafety dissecting table is applied to dry dissecting environment, no air hood can be arranged on the dissecting table. In contrast, when the biosafety dissecting table is applied to wet dissecting environment, the dissecting table preferably needs to be provided with an air hood.

[0079] Preferably, the filter can have different filtering levels, such as primary filtering function, intermediate filtering function or high-level filtering function.

[0080] In some embodiments, at least one first optical marker is further arranged on the first placement table, and at least one second optical marker is arranged on the limiting component; wherein the optical marker is used to mark the instrument component, such as being bound to the limiting component and the first placement table by pasting, binding or other ways. The optical marker can be positioned by a camera.

[0081] In some embodiments, each optical marker bound by different instruments, such as the limiting component and the first placement table, is unique, that is, each optical marker can be individually identified.

[0082] In some embodiments, the optical marker can be a fluorescent marker, and the optical marker can have a clear outline to facilitate optical positioning. In some embodiments, the positioning of the optical marker can be completed by using infrared positioning.

[0083] In some embodiments, the current frame image (which covers the limiting component and the first placement table) can be read by at least one optical positioning camera, the optical marker in the image can be detected, and the two-dimensional pixel coordinates of the optical marker can be obtained. According to the calibration parameters of the optical positioning camera, the two-dimensional pixel coordinates of the optical marker are stereoscopically matched, and the three-dimensional coordinate values of the optical marker in the measurement coordinate system are calculated from the two-dimensional pixel coordinates, that is, the positioning of the optical marker is completed. Subsequently, the lighting device can also follow the positioning function of the camera to follow autonomously, for example, the existing shadowless lamp following mode can be used.
