[0040] It also includes an absorption mechanism, which is arranged on the supporting foot 1. The absorption mechanism is used to absorb the odor emitted by the medicine and the medicine dripping on the net frame 5. The absorption mechanism includes a liquid storage barrel 101, which is connected to the supporting foot 1 at one end close to the discharge port of the dissecting table 4 by bolts. The liquid storage barrel 101 is used to store the inhaled medicine. The liquid storage barrel 101 is connected to an exhaust fan 102 by bolts. The exhaust pipe of the exhaust fan 102 is connected to the top side of the liquid storage barrel 101. A connecting pipe 103 is connected between the liquid storage barrel 101 and the discharge port of the dissecting table 4. The bottom side of the liquid storage barrel 101 away from the exhaust fan 102 is connected to a drain valve 104.

[0041] It also includes a push-pull frame 11, which is slidably connected to the dissecting table 4. One end of the push-pull frame 11 close to the drainage port of the dissecting table 4 is connected to a scraper 12 by bolts. The scraper 12 is in contact with the bottom of the dissecting table 4. The scraper 12 is used to scrape off the medicine and human specimen debris attached to the dissecting table 4.

[0042] At first, the limit strip 71 is pressed against the synchronous frame 72, the tension spring 74 is stretched, and the crankshaft 78 is pressed against the first crank 771 through the sliding frame 772, so that the clip 77 is in an expanded state through the first crank 771. First, the operator places the human specimen on the mesh frame 5, and then places the forearm of the human specimen on a set of sliding seats 76 away from the discharge outlet of the dissecting table 4, and then moves the other set of sliding seats 76 to the ankle of the human specimen. At the same time, the operator turns on the vacuum pump 102. The vacuum pump 102 will start to extract the air in the dissecting table 4 through the liquid storage barrel 101 and the connecting pipe 103, so that the smell of the medicine emitted from the human specimen and the dripping medicine will be sucked into the dissecting table 4 through the mesh frame 5, and then the medicine will gather to the middle through the bottom of the arc-shaped structure of the dissecting table 4 and flow to the discharge outlet of the dissecting table 4, and then the medicine enters the liquid storage barrel 101 through the connecting pipe 103. In this way, by absorbing the smell of the medicine emitted by the human specimen, and absorb the dripping medicine, thereby reducing the emission of medicine smell and the accumulation of medicine on the mesh frame 5 when dissecting human specimens, thereby reducing the discomfort of the operator, thereby enhancing the use effect of the human dissection table 4; when the operator needs to display the human specimen, the operator controls the output shaft of the servo motor 62 to rotate and drive the screw rod 63 to rotate, the rotation of the screw rod 63 will drive the lifting frame 2 to move upward through the connecting frame 61, the upward movement of the lifting frame 2 will drive the dissection table 4 to move upward through the support seat 3, and then control the extension of the telescopic rod of the hydraulic rod 65, the extension of the telescopic rod of the hydraulic rod 65 will push the dissection table 4 to tilt through the connecting block 66, when it is tilted to the required angle, the operator closes the hydraulic rod 65, in this way, when it is necessary to display the human specimen, the dissection table 4 is raised and tilted, which is conducive to displaying the human specimen, so that the operator can better teach, thereby further enhancing the use effect of the human dissection table 4;When the dissecting table 4 is tilted, the limit bar 71 no longer presses against the synchronous frame 72, and the tension spring 74 is reset, driving the synchronous frame 72 to move downward. The downward movement of the synchronous frame 72 will drive the gear 79 to rotate half a circle through the rack structure of the synchronous frame 72. The rotation of the gear 79 will drive the crankshaft 78 to rotate half a circle. The rotation of the crankshaft 78 will squeeze the sliding frame 772 to move downward. The downward movement of each sliding frame 772 will drive the two clamps 77 of each group to rotate in a direction close to each other through the two first cranks 771 of each group. After the clamps 77 rotate, they will clamp the limbs of the human specimen through the buffer pads 773 made of silicone material, and then the contact of the buffer pads 773 made of silicone material can reduce the wear on the human specimen. When 772 moves downward, it will drive the rotating frame 82 to rotate downward through the connecting arm 84, so that each rotating frame 82 drives the two limiting posts 83 of each group to move away from each other through the spiral groove of the rotating frame 82. After the limiting posts 83 move a certain distance, they will abut against the groove of the friction strip 85, thereby increasing the friction between the limiting posts 83 and the friction strip 85. After the limiting posts 83 abut against the friction strip 85, the sliding seat 76 will be locked in the current position. In this way, after the dissecting table 4 is tilted, the limbs of human specimens of different sizes will be clamped and locked in the current position through the clamping piece 77, so that human specimens of different sizes can be fixed when the dissecting table 4 is tilted, so that the human specimens can be moved freely when the dissecting table 4 is tilted. After the human body specimen is anatomically taught, the operator controls the telescopic rod of the hydraulic rod 65 to retract so that the anatomical table 4 returns to the horizontal state. At the same time, the limit bar 71 presses against the synchronous frame 72 again, so that the synchronous frame 72 moves upward, and the tension spring 74 returns to the initial state. The upward movement of the synchronous frame 72 drives the crankshaft 78 to reset through the gear 79. The reset of the crankshaft 78 drives the sliding frame 772 to reset. The reset of the sliding frame 772 drives the clamp 77 to expand and return to the initial state through the crankshaft 78. When the sliding frame 772 is reset, it drives the rotating frame 82 to reset through the connecting arm 84. The reset of the rotating frame 82 makes the four groups The limit column 83 is reset, so that the limit column 83 no longer locks the sliding seat 76 by abutting against the friction strip 85. Then the operator removes the human specimen from the net frame 5. Then the operator pushes and pulls the push-pull frame 11 and rinses the net frame 5 and the dissecting table 4 with clean water. The movement of the push-pull frame 11 will scrape off the medicine and human specimen debris attached to the bottom of the dissecting table 4 through the scraper 12, which is conducive to cleaning the dissecting table 4. Then the operator places the container for holding waste liquid at the drain valve 104 and turns off the vacuum pump 102. Then the operator opens the drain valve 104, and the medicine collected in the liquid storage barrel 101 flows into the container from the drain valve 104. Then the operator closes the drain valve 104. ;

The end is connected with a guide column 92 by bolts, and a lifting frame 93 is slidably connected in the U-shaped groove of the net frame 5. The lifting frame 93 is used to prevent the medicine from flowing out of the dissecting table 4. The lifting frame 93 is slidably connected with the guide column 92. A sliding groove is opened on the bottom side of the lifting frame 93 close to the guide column 92. Two guide grooves are opened in the middle of the lifting frame 93. The sliding groove of the lifting frame 93 is slidably connected with the other end of the second crank 91. The second crank 91 is used to drive the sliding frame to rise and fall through the sliding groove of the lifting frame 93.

[0044] When the synchronous frame 72 moves downward, it will squeeze the end of the second crank 91 outside the dissecting table 4 to rotate downward, and the torsion spring 94 will be twisted to make the other end of the second crank 91 rotate upward. The upward rotation of the other end of the second crank 91 will squeeze the lifting frame 93 to move upward through the sliding groove of the lifting frame 93. The upward movement of the lifting frame 93 will block the end of the net frame 5 close to the second crank 91. After the lifting frame 93 is raised, it will block the medicine flowing downward along the net frame 5, and then guide the medicine into the dissecting table 4 through the guide groove of the lifting frame 93. In this way, after the dissecting table 4 is tilted, the lifting frame 93 is used to cover the lower end of the tilted mesh frame 5, thereby blocking the medicine flowing downward along the mesh frame 5, so that the medicine is not easy to drip on the ground and pollute the teaching environment, thereby further enhancing the use effect of the human dissecting table 4; after the dissecting table 4 is reset, the synchronous frame 72 will reset upward, and after the synchronous frame 72 is reset, it will no longer squeeze the second crank 91, and the torsion spring 94 is reset, so that the second crank 91 rotates and resets, and after the second crank 91 is reset, the lifting frame 93 is driven to reset through the sliding groove of the lifting frame 93.
