Description

Technical Field

[0001] The present invention belongs to the technical field of pathological specimen sampling assistance, and specifically relates to a gross specimen sampling method and an online auxiliary system. Background Art

[0002] Gross specimen collection involves cutting tissue blocks of appropriate size from the gross specimen, based on the purpose and requirements of the pathological examination, for preparation and microscopic examination. Obtaining appropriate tissue is crucial for achieving diagnostic results. This requires not only that the material be as fresh as possible, but also that it be of sufficient quantity and good quality.

[0003] When taking gross specimens, a pathologist is required to take the specimens, and an assistant physician is also required to record the location, size, number of times the specimens are taken, the method of taking the specimens, and the gross tissue visible to the naked eye. Since the entire sampling process is long and there are many data and parameters that need to be recorded, data omissions and errors are prone to occur due to negligence. In addition, when taking gross specimens, the position of the specimen will be more inclined to the pathologist who takes the specimens, which will affect the observation angle, observation position, and observation effect of the assistant physician. In order to solve the above problems and assist in the observation of the gross specimen sampling process, the present invention provides the following technical solutions. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for obtaining gross specimens and an online auxiliary system to solve the problems in the prior art such as a long sampling process, multiple sampling data parameters, and poor observation position which may adversely affect the sampling data recording results.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] An online auxiliary system for gross specimen collection, comprising:

[0007] The operating collection device includes a horizontally arranged collection platform, an auxiliary platform is horizontally arranged above the collection platform, and the auxiliary platform can reciprocate in the vertical direction;

[0008] The auxiliary platform is provided with a lighting module on one side close to the collection platform, and the lighting module includes a plurality of lighting units distributed in a rectangular array;

[0009] An image acquisition module is further provided on the side of the auxiliary table close to the acquisition table, and the image acquisition module can move to any point on the side of the auxiliary table close to the acquisition table;

[0010] The speech recognition module is used to identify the input speech information, extract the key information and enter it into the database module;

[0011] The working method of the above-mentioned online auxiliary system for gross specimen collection includes the following steps:

[0012] The first step is to place the gross specimen on the collection table, wake up the online auxiliary system, enter the relevant information of the gross specimen through the voice recognition module, and the image acquisition module collects the image information of the gross specimen before sampling;

[0013] In the second step, during the sampling process of the gross specimen, the voice recognition module recognizes the input voice information, extracts the key information and enters it into the database module. During the sampling process, the position of the gross specimen is tracked by the image acquisition module. When the controller receives the acquisition instruction, the sampling camera unit obtains the image centered on the gross specimen and transmits it to the database module for storage.

[0014] As a further solution of the present invention, a driving rod is slidably installed on one side of the auxiliary table close to the acquisition table, and the two ends of the driving rod are slidably installed on two opposite sides of the auxiliary table. The driving rod is driven to reciprocate in a straight line on the auxiliary table through a screw structure, and an image acquisition module is slidably installed on the driving rod, and the image acquisition module is driven to reciprocate in a direction perpendicular to the movement direction of the driving rod.

[0015] As a further solution of the present invention, the method for the image acquisition module to acquire image information is:

[0016] S1. First, the camera unit acquires image information of the collection platform, reads the outline of the collection platform, obtains the position of the collection platform area in the image, and obtains the position of the gross specimen on the collection platform based on the color difference, thereby determining the position of the gross specimen;

[0017] S2. Moving the sampling and imaging unit to above the gross specimen according to the position of the gross specimen acquired in step S1, acquiring image information of the gross specimen again through the sampling and imaging unit, and acquiring the plane geometric center of the gross specimen through image information processing;

[0018] S3. Adjust the position of the sampling and imaging unit according to the plane geometric center obtained in step S2 so that the sampling and imaging unit is located directly above the gross specimen, and then obtain image information of the gross specimen through the sampling and imaging unit.

[0019] As a further solution of the present invention, the collection instruction is input through a voice recognition module, and the collection instruction is a pre-set word.

[0020] As a further solution of the present invention, the method for the image acquisition module to track the position of the gross specimen is:

[0021] S21. Based on the first step, capturing images at predetermined intervals to obtain unobstructed contour information of the gross specimen, comparing the obtained contour information with the previously obtained gross specimen contour information, and obtaining a position of the obtained contour information within the previously obtained gross specimen contour information, thereby obtaining a position of the gross specimen;

[0022] S22, obtaining the plane geometric center of the gross specimen at this time, obtaining the position of the plane geometric center in the picture, and adjusting the position of the sampling camera unit through the controller so that the plane geometric center is located at the center of the picture.

[0023] As a further solution of the present invention, in the second step, during the process of sampling the gross specimen, the lighting module is controlled by the controller according to the position of the gross specimen;

[0024] Specifically, the following steps are included:

[0025] SS1. Obtain the location information of the image acquisition module;

[0026] SS2. With the image acquisition module as the center, turn on the lighting units in a circular area with a preset radius R in the lighting module. Then, based on the position information of the image acquisition module, obtain the horizontal or vertical coordinate corresponding to the driving rod, and then turn off one or more rows of lighting units corresponding to the driving rod. This saves energy while avoiding leaving obvious shadows on the acquisition platform.

[0027] As a further solution of the present invention, the position information is the orthographic projection coordinate position of the image acquisition module on a plane rectangular coordinate system established based on a side of the auxiliary platform close to the acquisition platform.

[0028] Beneficial effects of the present invention:

[0029] (1) When the present invention is working, it can automatically record the information that needs to be recorded through voice commands, and can also track the position of the gross specimen through the image acquisition module. When the voice command is issued, the corresponding image information can be quickly acquired. The whole process does not require the doctor to assist in finding the angle, and the image acquisition is carried out in practice. The position of the gross specimen in the acquired image is centered, which is convenient for observation. At the same time, it will not affect the activities of the doctor who collects the specimen, greatly reducing the workload of the sampling work and improving the quality of information recording during the sampling process;

[0030] (2) The present invention actively controls the lighting range, thereby avoiding leaving obvious shadow areas and preventing a large number of distributed lighting units from working simultaneously, which would cause reflected light from the surroundings to affect the gross specimen collection work, thereby providing good lighting conditions for the specimen collection doctor;

[0031] (3) The present invention can quickly locate the position of a gross specimen by using the camera unit during the startup phase.

DETAILED DESCRIPTION

[0033] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] An online auxiliary system for gross specimen collection, comprising:

[0035] The operating collection device includes a collection table, which is horizontally arranged for placing gross specimens. An auxiliary table is horizontally arranged above the collection table, and the auxiliary table can reciprocate in the vertical direction.

[0036] In one embodiment of the present invention, the auxiliary platform is slidably mounted on support columns, which are four columns perpendicular to the plane of the collection platform and respectively arranged at the four corners of the collection platform, so that the collection platform and the auxiliary platform form an integrated structure;

[0037] The auxiliary platform is provided with a lighting module on one side close to the collection platform, and the lighting module includes a plurality of lighting units distributed in a rectangular array;

[0038] An image acquisition module is further provided on the side of the auxiliary table close to the acquisition table, and the image acquisition module can move to any point on the side of the auxiliary table close to the acquisition table;

[0039] In one embodiment of the present invention, a driving rod is slidably mounted on a surface of the auxiliary table adjacent to the acquisition table, and both ends of the driving rod are slidably mounted on two opposite side edges of the auxiliary table. The driving rod is driven by a lead screw structure to reciprocate linearly on the auxiliary table. An image acquisition module is slidably mounted on the driving rod, and the image acquisition module is driven by a lead screw structure or a linear cylinder to reciprocate perpendicularly to the direction of movement of the driving rod.

[0040] An image acquisition module is used to obtain image information and / or video information of the doctor when performing specimen collection operations;

[0041] The speech recognition module is used to identify the input speech information, extract the key information and enter it into the database module;

[0042] Key information includes shape, color, size, texture, hardness, etc.;

[0043] Database module, used to store input data information;

[0044] A method for obtaining a gross specimen is performed using the above-mentioned online auxiliary system, and the method comprises the following steps:

[0045] The first step is to place the gross specimen on the collection table, wake up the online auxiliary system, enter the relevant information of the gross specimen through the voice recognition module, and the image acquisition module collects the image information of the gross specimen before sampling;

[0046] The method for the image acquisition module to collect image information is:

[0047] S1. First, the camera unit acquires image information of the collection platform, reads the outline of the collection platform, obtains the position of the collection platform area in the image, and obtains the position of the gross specimen on the collection platform based on the color difference, thereby determining the position of the gross specimen;

[0048] This step allows the position of the gross specimen to be quickly located by the imaging unit during the startup phase. Specifically, the outline of the acquisition platform is first read to eliminate the interference of the color of objects outside the acquisition platform on the determination of the gross specimen position. The position of the gross specimen is then determined by analyzing the color difference.

[0049] S2. Moving the sampling and imaging unit to above the gross specimen according to the position of the gross specimen acquired in step S1, acquiring image information of the gross specimen again through the sampling and imaging unit, and acquiring the plane geometric center of the gross specimen through image information processing;

[0050] S3. Adjust the position of the sampling and imaging unit according to the plane geometric center obtained in step S2 so that the sampling and imaging unit is located directly above the gross specimen, and then obtain image information of the gross specimen through the sampling and imaging unit.

[0051] This step obtains the exact position of the gross specimen through two positionings, thereby obtaining an image with the plane geometric center of the gross specimen at the center of the picture, so that the acquired gross specimen image is evenly distributed and the picture is straight, which is convenient for subsequent observation.

[0052] In the second step, during the sampling process of the gross specimen, the voice recognition module recognizes the input voice information, extracts the key information and enters it into the database module. During the sampling process, the image acquisition module tracks the position of the gross specimen. When the controller receives the acquisition instruction, the sampling camera unit obtains an image centered on the gross specimen and transmits it to the database module for storage.

[0053] The acquisition instructions can be input through the voice recognition module to achieve contactless control;

[0054] The collection instruction can be a pre-set word;

[0055] The method for the image acquisition module to track the position of the general specimen is:

[0056] S21. Based on the first step, capturing images at predetermined intervals to obtain unobstructed contour information of the gross specimen, comparing the obtained contour information with the previously obtained gross specimen contour information, and obtaining a position of the obtained contour information within the previously obtained gross specimen contour information, thereby obtaining a position of the gross specimen;

[0057] Since the arms and other objects may partially block the gross specimen during the sampling process, thus affecting the acquisition of complete gross specimen image information, partial contour information of the gross specimen is obtained in this step, and the current position of the gross specimen is determined based on the exposed contour information and the image information collected in the first step;

[0058] In this step, when the complete outline of the gross specimen is collected, the outline information is used as the current gross specimen outline information and is used when the gross specimen is positioned next time;

[0059] S22, obtaining the plane geometric center of the gross specimen at this time, obtaining the position of the plane geometric center in the picture, and adjusting the position of the sampling camera unit through the controller so that the plane geometric center is located at the center of the picture.

[0060] This method can well determine the position of the gross specimen when the gross specimen is large, so that the gross specimen is always in the center of the picture, making the recorded image information more convenient to view and able to quickly record the image, reducing the difficulty and workload of the assistant doctor;

[0061] In the second step, during the process of sampling the gross specimen, the controller controls the operation of the lighting module according to the position of the gross specimen to reduce or eliminate shadows;

[0062] Specifically, the following steps are included:

[0063] SS1. Obtain the location information of the image acquisition module;

[0064] The position information here is the orthographic projection coordinate position of the image acquisition module on the plane rectangular coordinate system established based on the side of the auxiliary platform close to the acquisition platform;

[0065] SS2. With the image acquisition module as the center, turn on the lighting units in a circular area with a preset radius R in the lighting module. Then, based on the position information of the image acquisition module, obtain the horizontal or vertical coordinate corresponding to the driving rod, and then turn off one or more rows of lighting units corresponding to the driving rod. This saves energy while avoiding leaving obvious shadows on the acquisition platform.

[0066] Since the image acquisition module is at a certain distance from the lighting unit when it is working, it is easy to leave a shadow on the acquisition table when there is a lighting unit working above it, thereby affecting the doctor's gross sampling. The present invention actively controls the lighting range, and while avoiding leaving obvious shadow areas, it can also avoid a large number of distributed lighting units working at the same time, causing the reflected light from the surroundings to affect the gross sampling work, thereby providing good lighting conditions for the sampling doctor.

[0067] In one embodiment of the present invention, it is also possible to record the auxiliary table heights commonly used by different doctors when performing collection work, and automatically adjust the height of the auxiliary table after identity recognition when the corresponding doctor performs collection work.

[0068] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
