Description

Technical Field

[0001] The invention relates to the technical field of cutting and processing of bone-containing or hard samples in biology and medicine, in particular to a full-automatic bone sawing machine for cutting bone samples. Background Art

[0002] Extracting bone or hard samples during medical treatment is primarily to clarify the nature of bone lesions, assess the extent of bone tissue damage, or analyze metabolic abnormalities, providing a key basis for diagnosis and treatment planning. However, bone samples are hard and have a special structure. Manual cutting can easily lead to sample fragmentation and irregular edges, affecting the accuracy of subsequent pathological examinations or research. The fully automatic bone saw can achieve uniform and complete cutting of bone samples by precisely controlling the cutting speed, pressure, and angle, preserving the original morphology of the lesion area to the greatest extent possible. It also reduces manual operation errors, lowers the risk of sample contamination, and ensures the reliability of subsequent analysis results such as tissue sectioning and molecular testing. It is an important device for ensuring the quality of bone sample processing.

[0003] Bone samples refer to biological samples with bone tissue as the main research object. They can be divided into various types according to their purpose and processing method. They are widely used in fields such as archaeology, medicine, forensic medicine, and materials science. When testing bone samples, it is necessary to use a bone saw to cut the bone samples into the required shape. Some bone cutting machines consist of a saw blade and a cutting table. When in use, the staff starts the saw blade through the control element, making the saw blade move back and forth at high speed. Then the staff manually pushes the bone sample to move it along the cutting platform, thereby using the saw blade to cut the bone sample. However, the bone cutting machine has no protective parts, and the operator pushes the sample through the saw blade to complete the cutting. The risk of hand injury to the operator is extremely high. In addition, biological debris generated during the sample cutting process splashes into the surrounding environment, forming aerosols with high infectious risks, causing biological contamination of the surrounding environment. In particular, when it is impossible to confirm whether the sample is an infectious sample, it is easy to lead to the spread of infectious diseases. At the same time, it is impossible to complete uniform cutting of the sample. For this reason, we propose a fully automatic bone saw for bone sample cutting. Summary of the Invention

The fine filter 10 and the fine filter 11 are both fixed to the air outlet of the fan 9 by bolts.

[0038] The working principle of the fully automatic bone sawing machine for cutting bone samples provided by the present invention is as follows: when using the device to cut the bone sample, first, the external low-pressure water pipe is connected to the cooling water head 51, and the flip cover 53 is flipped upward around the hinge by the handle 54 to open, and then the bone sample is fixed to the sample table 332, and then the bone sample is fixed to the sample table 332 by the sample clamp 333 (the sample clamp 333 adopts a loose-leaf structure to achieve flexible addition and subtraction of pages, and the pages are fixed by loose-leaf rings to clamp and fix the bone sample), and then the flip cover 53 is flipped downward around the hinge to close, and then the controller 41 starts the motor 25 so that its output shaft drives the wire storage barrel 22 to rotate alternately in forward and reverse directions or unidirectionally. During the rotation of the wire storage barrel 22, it drives its own cutting line 24 through the auxiliary support of the cutting wheel 23 and is controlled by the controller to rotate forward and reverse. The cutting wire 24 can be moved alternately back and forth or unidirectionally (the cutting wire 24 can be made of diamond cutting wire, molybdenum wire or copper wire). The cutting wire can be directly driven to cut by the mechanical motion structure. At the same time, the cutting wire 24 can also be connected to the negative electrode of the high-frequency pulse power supply as a tool electrode, and the electric spark discharge principle is used to realize the wire cutting operation of the bone sample (the diameter of the cutting wire 24 ranges from 0.05mm to 5mm. The thinner the cutting wire, the less sample information loss is caused during the cutting process, thereby protecting the cut sample). The bone residue adhered to the cutting wire 24 during its operation is intercepted by the cutting baffle 56. The cutting baffle 56 can be made of metal such as aluminum plate or plastic such as nylon plate. At the same time, the external low-pressure cooling water enters the cooling water head 51 through the external low-pressure water pipe and flows out through the cooling water head 51, thereby cooling the cutting wire 24 and the sample below the cooling water head 51.

[0039] At the same time, the controller 41 starts the motor 2 3114 so that its output shaft drives the screw 1 3113 to rotate, and the screw 1 3113 is connected through a thread so that the moving seat 1 3112 slides along the guide rail 1 3111, thereby realizing the A-axis movement of the moving seat 1 3112. At the same time, the controller 41 starts the motor 5 3123 so that its output shaft drives the screw 3 3122 to rotate, and the screw 3 3122 is connected through a thread so that the moving seat 1 3112 moves along the guide rail 3 3121, thereby realizing the B-axis movement of the moving seat 1 3112. Through the coordinated work of the A-axis system and the B-axis system, the movement accuracy and equipment stability of the moving seat 1 3112 are improved, thereby performing X-axis adjustment on the wire cutting part of the fully automatic bone sawing machine. The controller 41 starts the motor 3 324 so that its output shaft drives the screw 2 323 to rotate, and during the rotation of the screw 2 323, the moving seat 2 322 is connected through a thread so that the moving seat 1 322 moves along the guide rail The guide rail 2 321 slides, thereby adjusting the Y-axis of the wire cutting part of the fully automatic bone sawing machine. The controller 41 starts the motor 4 331 so that its output shaft drives the sample table 332 to rotate, thereby adjusting the Z-axis rotation of the wire cutting part of the fully automatic bone sawing machine. Power transmission can be achieved between the motor 2 314 and the screw 1 313, and between the motor 3 324 and the screw 2 323 by installing a coupling. The output end of the controller 41 is electrically connected to the input ends of the motor 2 314, the motor 3 324, the motor 5 3123 and the motor 4 331 respectively. The controller 41 can accurately adjust the cutting position of the wire cutting part of the fully automatic bone sawing machine by the motor 2 314, the motor 3 324, the motor 5 3123 and the motor 4 331 through data such as the pitch of the screw 1 313, the screw 2 323 and the screw 3 3122, thereby achieving cutting uniformity of the corresponding specifications of the bone sample.

[0040] During the use of the fully automatic bone sawing machine, the controller 41 starts the HMI42, and the staff can program and input the internal instructions of the controller 41 through the HMI42, thereby limiting the running trajectory between the various components of the device through program programming, further ensuring the uniformity of the shape of the bone sample cut by the device, and no staff intervention is required during the bone sample cutting process. During the use of the fully automatic bone sawing machine, the components on the left end of the device are wrapped and protected by the shell 52, and the cutting part of the bone sample is isolated from the outside world by the flip cover 53 to prevent the external environmental pollution and biological pollution caused by the sample bone residue during the bone sample cutting process. The bone sample cutting inside the device can be observed through the observation window 55. After the full-automatic bone sawing machine is used, The controller 41 activates the solenoid valve 1 64 to allow the external high-pressure water to enter the high-pressure water pipe 61 through the external pipe. The high-pressure water in the high-pressure water pipe 61 passes through the detergent barrel 62, carrying the detergent in the detergent barrel 62. The high-pressure water and the detergent are sprayed out through the high-pressure water pipe 61 through the high-pressure multi-directional automatic spray head 63, thereby spraying and cleaning the bone sample cutting part inside the device. The high-pressure spray water inside the device slides along the wall of the device into the receiving tray 65, and the impurities in the water are filtered by the filter plate 66 of the receiving tray 65 using the filter pore diameter. At the same time, the controller 41 opens the solenoid valve 2 6 to discharge the filtered water in the receiving tray 65 through the drain pipe 67, thereby performing a self-cleaning operation on the inside of the device.

[0041] During the use of the device, a hydrophobic coating and an antibacterial coating are sprayed on the inner walls of the outer shell 52 and the flip cover 53, and the probability of bone sample cuttings adhering to the outer shell 52 and the flip cover 53 is reduced by utilizing its non-sticky characteristics, thereby achieving the purpose of easy cleaning. The refueling pump 7 is started by the controller 41, and the refueling pump 7 is operated to transport lubricating oil to the lead screw and guide rail in the device through the pipeline 8, thereby lubricating them and ensuring the operating accuracy and stability of the motion structure. The controller 41 starts the fan 9, and the fan 9 is operated to perform an exhaust operation on the bone sample cutting part in the device, thereby utilizing air pressure to collect floating potential biohazard substances generated by bone sample cutting, and filtering them in turn through the fine filter 10 and the fine filter 11 (the sieve size of the fine filter 10 is larger than the sieve size of the fine filter 11), and the fine filter 10 and the fine filter 11 are both fixed to the air outlet of the fan 9 by bolts.

[0042] It is worth noting that the motor 1 25 disclosed in the above embodiment can adopt DT-D02, the motor 2 314, the motor 324, the motor 5 3123 and the motor 4 331 can all adopt 60ST-M00630LBX, the controller 41 can adopt AK-12S-220, the HMI 42 can adopt an EK touch screen, the solenoid valve 1 64 and the solenoid valve 2 68 can both adopt ZCT miniature stainless steel solenoid valves, the refueling pump 7 can adopt an FP-12 DC electric gear oil pump, and the fan 9 can adopt AS05006L5. The controller 41 controls the operation of the motor 1 25, the motor 2 314, the motor 3 324, the motor 4 331, the motor 5 3123, the HMI 42, the solenoid valve 1 64, the solenoid valve 2 6, the refueling pump 7 and the fan 9, all adopting methods commonly used in the prior art.
