Description

Technical Field

[0001] This utility model relates to the technical field of medical testing, and in particular to a method for cutting tissue biopsy specimens using a projection-based measuring method. Background Technology

[0002] Tissue biopsy involves removing tissue samples from the body for pathological examination to diagnose diseases. This process is crucial for determining the nature of lesions, understanding their progression, predicting prognosis, guiding treatment plans, and monitoring drug efficacy. It provides clinicians with an accurate histological diagnosis, helps doctors develop treatment plans, predicts disease progression, and provides pathological and histological evidence for scientific research.

[0003] After the sample is removed from the human body, a sharp scalpel is used to cut a tissue block from the biopsy sample—this process is called sampling. Generally, the tissue block is about 0.2~0.3cm thick and about 1.5cm x 1.5cm x 0.3cm in size. The sampling site must be accurate, avoiding necrotic tissue or areas of obvious secondary infection. Sampling should be done at the boundary between the lesion and normal tissue, aiming to obtain the lesion tissue and a small amount of surrounding normal tissue.

[0004] The scalpel used for sample collection is generally a sharp surgical knife for quick operation. The process involves placing the tissue on a worktable, measuring the appropriate size using a ruler, and then cutting the tissue. Current worktables sometimes use a movable steel ruler for measurement, which is inconvenient as the operator already needs to control the sample with one hand and hold the scalpel with the other. Some worktables have a fixed steel ruler, but the sample must be brought close to the edge of the ruler for measurement, and this close contact between the ruler and the sample also affects the cutting motion. Therefore, improvements are necessary to make the operation more convenient. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems and provide a method for cutting tissue biopsy specimens with a fixed projection size.

[0006] The technical solution of this utility model is: a tissue biopsy specimen cutting table with projection and measurement, characterized in that: the cutting table includes a lower table and a projection and measurement device located on the upper part of the table. The projection and measurement device includes a housing and a dimension line light projection component installed in the housing. The light emitted by the dimension line light projection component is projected onto the surface of the table to form dimension lines. This cutting table projects light downwards from above, forming dimension lines on the table surface. Therefore, during sampling and cutting, there is no need to manually control the ruler. The biopsy specimen is simply placed on the table, and the projected scale lines are counted according to the required size, and then cut with a knife. This achieves non-contact measurement, avoids contamination of the ruler, and eliminates the need to clean the ruler, significantly improving the efficiency of specimen cutting and sampling.

[0007] Preferably, the upper surface of the table is white. White facilitates the clear display of projected light.

[0008] Preferably, there are several dimension line projection components, evenly distributed inside the housing along its length. The dimension lines projected by each component onto the table are parallel to each other, and the distance between any two adjacent dimension lines projected onto the table is equal. This creates multiple parallel lines similar to a ruler, with each adjacent line representing a unit dimension. The size is determined by counting the number of lines.

[0009] Preferably, the dimension line projection components are arranged in n groups, parallel to each other along the width of the housing, where n ≥ 2. The dimension line projection components in each group are evenly spaced 'a' inside the housing. The starting scale line projected by the dimension line projection component of the nth group is offset by 'a / n' relative to the starting scale line projected by the (n-1)th group. The dimension lines projected by each group on the worktable are parallel to each other, and any adjacent dimension lines projected on the worktable have an equal spacing of 'a / n'. The staggered arrangement of multiple groups along the width direction increases the installation space for the dimension line projection components, allows for the projection of more dimension lines, increases the density of dimension lines, enables smaller unit dimensions, and improves the measurement accuracy of the projection measuring device.

[0010] Preferably, the lower part of the housing of the projection measuring device is provided with two legs, and the lower ends of the two legs are connected to the upper surface of the table.

[0011] Preferably, two magnets are embedded inside the table near the edge. These magnets are located near the top surface of the table and are covered by the top surface. The lower ends of the two legs are made of magnetic material to enable detachable installation between the table and the projection measuring device. The table surface is also a closed structure, which facilitates cleaning after use and prevents dirt from accumulating.

[0012] Preferably, the lower part of the housing includes a dimension line projection surface and a numerical projection surface. The dimension line projection surface is inclined downwards and arranged at an angle, and the dimension line projection component inside the housing is installed perpendicular to the dimension line projection surface. The numerical projection surface is parallel to the upper surface of the workbench, and the numerical projection surface has a plurality of numerical light projection components arranged at equal intervals along the length of the housing, projecting values ​​corresponding to the scale onto the edge of the workbench. This housing structure allows the projection measuring device to be placed on one edge of the workbench without occupying the space in the middle of the workbench, facilitating the cutting operation.

[0013] Preferably, the dimension line light projection component is a line laser.

[0014] Preferably, the plurality of numerical light projection components can project different values, projecting patterns of different values ​​onto the table.

[0015] Preferably, there are two projection measuring devices, which are arranged perpendicularly to each other. In this way, the two projection measuring devices project the longitudinal dimension line and the transverse dimension line onto the worktable, respectively. Thus, when cutting tissue blocks on the worktable, it is only necessary to move the tissue so that the tissue block to be cut is within the area enclosed by the corresponding longitudinal dimension line and transverse dimension line; then, the cutter can be used to cut along the corresponding longitudinal dimension line and transverse dimension line.

[0016] This invention relates to a tissue biopsy sample cutting table with projection and measuring capabilities. The cutting table includes a lower table and a projection and measuring device located on the upper part of the table. The projection and measuring device includes a housing and a dimension line light projection component installed within the housing. Light emitted by the dimension line light projection component is projected onto the surface of the table to form dimension lines. This cutting table projects light downwards from above, forming dimension lines on the table surface. Therefore, during sampling and cutting, there is no need to manually control the ruler. The biopsy sample is simply placed on the table, and the projected scale lines are counted according to the required size, followed by cutting with a knife. This achieves non-contact measuring, avoids contamination of the ruler, and eliminates the need for cleaning the ruler, significantly improving the efficiency of sample cutting and sampling.

[0017] It also provides multiple sets of horizontally staggered dimension line projection components, which not only provides more installation space for the dimension line projection components, but also increases the density of the projected dimension line light and improves the measurement accuracy of the fixed length.

[0030] Example 1: See Figure 1-5 The figure shows a tissue biopsy specimen cutting table with projection and measuring capabilities. The cutting table includes a lower table and a projection and measuring device located on the upper part of the table. The projection and measuring device includes a housing 1 and a dimension line light projection component 11 installed inside the housing 1. The light emitted by the dimension line light projection component 11 is projected onto the surface of the table to form dimension lines. This cutting table projects light downwards from above, forming dimension lines on the table surface. Therefore, during sampling and cutting, there is no need to manually control the ruler. The biopsy specimen is simply placed on the table, and the projected scale lines are counted according to the required size, and then cut with a knife. This achieves non-contact measuring, avoids contamination of the ruler, and eliminates the need to clean the ruler, significantly improving the efficiency of specimen cutting and sampling. The upper surface of the table is white. White facilitates the clear display of the projected light.

[0031] The aforementioned dimension line projection components 11 are numerous and evenly distributed inside the housing 1 along its length. The dimension lines projected by each dimension line projection component 11 onto the table are parallel to each other, and the distance between any two adjacent dimension lines projected onto the table is equal. This forms multiple parallel lines similar to a ruler, with the distance between adjacent lines representing a unit dimension. The dimension is determined by counting the number of lines.

[0032] The lower part of the housing 1 of the projection measuring device has two support legs 33, the lower ends of which are connected to the upper surface of the table. Two magnets 22 are embedded inside the table near the edge. After being inserted into holes, the magnets 22 are secured by plugs 21. The magnets 22 are located near the upper surface of the table and are covered by the upper surface. The lower ends of the two support legs 33 are made of a magnetic material. This allows for detachable installation between the table and the projection measuring device. The table surface remains a closed structure, facilitating cleaning after use and preventing dirt accumulation.

[0033] The lower part of the housing 1 includes a dimension line projection surface and a numerical projection surface. The dimension line projection surface is inclined downwards and arranged at an angle. The dimension line projection component inside the housing 1 is installed perpendicular to the dimension line projection surface. The numerical projection surface is parallel to the upper surface of the table. The numerical projection surface has a plurality of numerical light projection components 12 arranged at equal intervals along the length of the housing 1, projecting values ​​corresponding to the scale onto the edge of the table. This housing 1 structure allows the projection measuring device to be placed on one edge of the table without occupying the space in the middle of the table, which is beneficial for the cutting operation.

[0034] The aforementioned linear laser projection component 11 is a line laser. Chinese Patent No. 202220909796.0 provides a line laser module that can be used as this line laser. It is already commercially available and will not be discussed further here.

[0035] The aforementioned numerical light projection components 12 can project different values, thus projecting patterns of different values ​​onto the table. This can be achieved by placing image models or templates of different values ​​in front of the laser.

[0036] How to use this counter:

[0037] When in use, the dimension line light projection component 11 and the numerical light projection component 12 are activated to project several parallel dimension lines onto the white table surface. The corresponding dimension values, such as 0, 10, 20, etc., are projected onto the edge of the table, which facilitates comparison and measurement of the sample.

[0038] The operator uses one hand to adjust the placement of the sample and fix it on the table surface, while using the other hand to hold the knife and cut it. The size of the cut can be determined by counting the number of dimension lines. Cutting can be done along the projected dimension lines. The entire operation does not require worrying about how to control the ruler, reducing the difficulty of operation and improving the efficiency of operation.

[0039] Example 2: See Figure 6-10Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that in Example 2, the dimension line light projection components 11 are in n groups, arranged in parallel along the width direction of the housing 1, where n ≥ 2. The dimension line light projection components 11 in each group are distributed at equal intervals a inside the housing 1. The starting scale line projected by the dimension line light projection component 11 of the nth group is offset by a / n relative to the starting scale line projected by the (n-1)th group. The dimension lines projected by the dimension line light projection components 11 of each group on the table are parallel to each other, and the spacing between any adjacent dimension lines projected on the table is equal to a / n. Multiple groups can be staggered in the width direction, which can increase the installation space of the dimension line light projection components 11, realize the projection of more dimension lines, increase the density of dimension lines, and make the unit size smaller, thereby improving the measurement accuracy of the projection measuring device.

[0040] This embodiment uses the same method as Embodiment 1, and will not be described again.

[0041] Example 3: See Figure 11 Example 3 is basically the same as Example 1, and the similarities will not be repeated. The difference is that there are two projection measuring devices, which are arranged perpendicularly to each other. In this way, the dimension lines projected by the two projection measuring devices onto the worktable are the longitudinal dimension line and the transverse dimension line, respectively. Thus, when cutting tissue blocks on the worktable, it is only necessary to move the tissue so that the tissue block to be cut is within the area enclosed by the corresponding longitudinal dimension line and transverse dimension line; then, the cutter can be used to cut along the corresponding longitudinal dimension line and transverse dimension line.
