Description

Technical Field

[0001] The utility model relates to a biological cutting sampling device, belonging to the technical field of cutting sampling devices. Background Art

[0002] Sampling refers to the process of obtaining individuals or samples from a population, that is, the process of testing or observing the population through the testing of partial samples. Biological cutting sampling is usually used in medical experiments or biological experiments. In order to ensure that the cut test samples can meet the test standards, professional biological cutting sampling equipment is required for cutting sampling operations.

[0003] Existing biological cutting sampling devices usually require inspectors to perform pure manual cutting of the inspected body. However, when inspectors perform pure manual cutting of the inspected body, there will always be some slight jitters or slight changes in the cutting trajectory, resulting in the cut samples having rough boundaries, low precision, and uneven cutting trajectories, thereby reducing the cutting efficiency and increasing the sample loss. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a biological cutting sampling device with a regular cutting trajectory and high cutting efficiency.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A biological cutting sampling device comprises a fixed base, a support arm is movably mounted on the upper part of one end of the fixed base, and a sliding rod cutting structure is movably arranged on the end of the support arm; the sliding rod cutting structure comprises an open connecting frame, a diamond-shaped slide rail arranged at the opening of the open connecting frame, and a cutting structure slidably embedded in the diamond-shaped slide rail; the cutting structure comprises a first base, rollers symmetrically rotatably connected to the lower parts of both ends of the first base, a second base rotatably connected under the two rollers, and a cutting knife arranged on the lower surface of the second base, and the outer sides of the two rollers are provided with annular cutting grooves adapted to the diamond-shaped slide rails.

[0009] Furthermore, the rotating connection block and the rotating base are adjustably fixed via a first fixing buckle, and the second support rod and the first support rod are adjustably fixed via the first fixing buckle.

[0010] Furthermore, the second support rod and the third support rod are adjustably fixed via a second fixing buckle, and the third support rod and the sliding rod cutting structure are adjustably fixed via a second fixing buckle.

[0011] Furthermore, the first fixing buckle includes a second bolt and a first butterfly nut screwed on the end of the second bolt, and the second fixing buckle includes a screw rod and second butterfly nuts screwed on both ends of the screw rod.

[0012] Furthermore, a working groove is provided on the upper surface of the fixed base, and a working plate adapted to the working groove is arranged in the working groove.

[0022] like Figure 1-4 As shown, the biological cutting sampling device provided in this embodiment includes a fixed base 1, a support arm 2 is movably mounted on the upper surface of one end of the fixed base 1, and a sliding rod cutting structure 3 is movably arranged at the end of the support arm 2; the sliding rod cutting structure 3 includes an opening connection frame 4, a diamond slide rail 5 arranged at the opening of the opening connection frame 4, and a cutting structure 6 slidably embedded on the diamond slide rail 5; the cutting structure 6 includes a first base 7, rollers 8 symmetrically connected to the lower surface of both ends of the first base 7, a second base 10 rotatably connected under the two rollers 8, and a cutting knife 11 arranged on the lower surface of the second base 10, and the outer sides of the two rollers 8 are provided with annular cutting grooves 12 adapted to the diamond slide rail 5. The fixed base 1 can be used to support the support arm 2, and the support arm 2 is used to connect the sliding rod cutting structure 3 to the fixed base 1. At the same time, the support arm 2 can also adjust the height and angle of the sliding rod cutting structure 3, so as to better cut and sample the samples to be inspected; the open connecting frame 4 is used to rotatably connect the sliding rod cutting structure 3 to the support arm 2, and the diamond slide rail 5 facilitates the cutting structure 6 to slide and cut, preventing the cutting trajectory from changing. The cutting structure 6 is used to cut and sample the samples to be inspected; the roller 8 facilitates the cutting structure 6 to be embedded in the diamond slide rail 5 for limited sliding, while reducing the friction during sliding; the second base 10 is used to connect the cutting knife 11 under the two rollers 8, and use the cutting knife 11 to slide and cut the samples to be inspected, and the annular cutting groove 12 ensures that the cutting structure 6 can be slidably embedded in the diamond slide rail 5 through the two rollers 8.

[0023] The cutting knife 11 includes a connecting rod 101 connected to the lower surface of the second base 10 and a scalpel blade 102 arranged on the connecting rod 101. The scalpel blade 102 is fixed to the connecting rod 101 by a first bolt 9. The connecting rod 101 is used to connect the scalpel blade 102 to the second base 10. The scalpel blade 102 is used to cut and sample the sample to be inspected. The first bolt 9 facilitates the replacement and fixation of the scalpel blade 102 to prevent the sample from being contaminated by the unclean scalpel blade 102 during cutting and sampling, or the scalpel blade 102 is not sharp and affects the cutting.

[0024] The support arm 2 includes a first support rod 13, a second support rod 14 rotatably connected to the end of the first support rod 13, and a third support rod 15 movably connected to the end of the second support rod 14. A rotating connection block 16 is provided on the upper surface of the fixed base 1. The rotating connection block 16 is connected to the first support rod 13 through a rotating base 17. The first support rod 13, the second support rod 14 and the third support rod 15 all play the role of supporting and connecting the cutting structure 6. The rotating connection block 16 and the rotating base 17 facilitate the rotational connection of the first support rod 13 to the fixed base 1.

[0025] The rotating connecting block 16 and the rotating base 17 can be adjusted and fixed by a first fixing buckle 18, and the first fixing buckle 18 can adjust the first support rod 13 and the fixed base 1 to a desired angle and then lock and fix them; the second support rod 14 and the first support rod 13 can be adjusted and fixed by the first fixing buckle 18, and the second support rod 14 and the first support rod 13 can be adjusted to a desired angle and then lock and fix them.

[0026] The second support rod 14 and the third support rod 15 are adjustably fixed by a second fixing buckle 19, and the second support rod 14 and the third support rod 15 can be adjusted to a desired angle and then locked and fixed; the third support rod 15 and the sliding rod cutting structure 3 are adjustably fixed by a second fixing buckle 19, and the third support rod 15 and the sliding rod cutting structure 3 can be adjusted to a desired angle and then locked and fixed.

[0027] The first fixing buckle 18 includes a second bolt 20 and a first butterfly nut 21 screwed on the end of the second bolt 20, and the second fixing buckle 19 includes a screw rod 22 and a second butterfly nut 23 screwed on both ends of the screw rod 22. The first butterfly nut 21 and the second butterfly nut 23 can be tightened manually without the use of tools to simplify the operation. The first fixing buckle 18 is configured as a second bolt 20 and a first butterfly nut 21 to increase firmness and is used when a large angle adjustment is required. The second fixing buckle 19 is configured as a screw rod 22 and two second butterfly nuts 23 to facilitate fine angle adjustments.

[0028] The upper surface of the fixed base 1 is provided with a working groove 24, in which a working board 25 adapted to the working groove 24 is arranged. The working groove 24 is convenient for limiting and embedding the working board 25 to prevent the working board 25 from sliding when cutting the sample, and prevents the scalpel blade 102 from scratching the fixed base 1 when the working board 25 is cutting. At the same time, the working board 25 can be replaced at any time, thereby avoiding the cut sample from being contaminated due to unclean working board 25 during cutting.

[0029] The fixed base 1 is provided with a storage groove 26 on a side away from the support arm 2, and a storage box 27 is slidably arranged in the storage groove 26. Push rods 28 are arranged on both sides of the first base 7. The storage groove 26 is convenient for storing the storage box 27, and the storage box 27 is convenient for storing some cutting tools. The push rod 28 is convenient for pushing the cutting structure 6 to slide on the diamond slide rail 5.

[0030] like Figure 1-Figure 4 As shown, the principle of the biological cutting sampling device provided in this embodiment is as follows: when the device is in use, the first support rod 13 and the fixed base 1 are first adjusted to a vertical or required angle, and then the support arm 2 is fixedly locked on the fixed base 1 by manually tightening the first butterfly nut 21 on the first fixing buckle 18 to ensure that there is no shaking; then the angle between the second support rod 14 and the first support rod 13 is adjusted to the required size by visually measuring the approximate height, and then the second support rod 14 is fixedly locked on the first support rod 13 by manually tightening the first butterfly nut 21 on the first fixing buckle 18 to ensure that there is no shaking; then the angle between the third support rod 15 and the second support rod 14 is adjusted to the required size, and the third support rod 15 and the second support rod 14 are temporarily fixed by the second fixing buckle 19, and then the opening angle between the sliding rod cutting structure 3 and the third support rod 15 is adjusted to the diamond slide rail 5 and the fixed base 1 are in a parallel state, and then the sliding rod cutting structure 3 and the third support rod 15 are temporarily fixed by the second fixing buckle 19;

[0031] After the preliminary preparation work is done, a new working plate 25 can be placed in the working groove 24, and then a new scalpel blade 102 can be tightened and fixed on the connecting rod 101 by the first bolt 9, and the subject to be inspected can be placed on the working plate 25. According to the condition of the subject to be inspected, the angle of the opening between the third support rod 15 and the second support rod 14 can be finely adjusted. At the same time, the angle of the opening between the sliding rod cutting structure 3 and the third support rod 15 can also be finely adjusted. However, during the adjustment, it is necessary to ensure that the diamond slide rail 5 is always parallel to the fixed base 1. After the fine adjustment is completed, the connection between the second support rod 14 and the third support rod 15 and the connection between the third support rod 15 and the sliding rod cutting structure 3 can be fixed and locked by manually tightening the screw rod 22 and the second butterfly nut 23 to prevent shaking when the subject to be inspected is slidingly cut and sampled;

[0032] Then, the push rod 28 on one side of the first base 7 can be pushed at a uniform speed, so that the cutting structure 6 can slide on the diamond slide rail 5 through the roller 8 limit card, thereby driving the scalpel blade 102 on the cutting knife 11 to slide and cut the inspected body on the working plate 25 for sampling; the operator only needs to give a sliding thrust, and the operator does not need to hold the knife himself, so as to ensure as much as possible that the cut and sampled samples will not have rough boundaries, low precision, and uneven cutting tracks. At the same time, the device can also adjust the opening angle of the first support rod 13 and the fixed base 1 to perform sliding bevel sampling at a certain angle on the inspected body.
