[0082] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 The driving assembly includes: a crankshaft 91, which is rotatably mounted on the side of the outer frame 1 through a fixing frame, and the crankshaft 91 is located directly above the liquid guide box 6; a plurality of collars 92, which are rotatably mounted on the crankshaft 91; a plurality of connecting rods 93, which are respectively arranged on the plurality of collars 92, and the bottom end of the connecting rod 93 is hinged to the top end of the push rod 77; a driven bevel gear 94, which is fixedly mounted on one end of the crankshaft 91; a rotating shaft 95, which is rotatably mounted on the side of the outer frame 1; a driving bevel gear 96, which is fixedly mounted on the end of the rotating shaft 95, and the driving bevel gear 96 is meshed with the driven bevel gear 94; a one-way Bearing 97 is mounted on the output end of the servo motor 8, the inner ring of the one-way bearing 97 is fixedly connected to the outer wall of the output end of the servo motor 8, and the one-way bearing 97 is connected to the rotating shaft 95 through the driven wheel and the synchronous belt transmission; when the servo motor 8 rotates forward, the rotating shaft 95 and the driving bevel gear 96 can be driven to rotate through the one-way bearing 97, the driven wheel and the synchronous belt, and the driving bevel gear 96 is meshed with the driven bevel gear 94, thereby driving the crankshaft 91 to rotate. During the rotation of the crankshaft 91, the push plate 76 can be pushed back and forth through the connecting rod 93 and the push rod 77.

[0083] Reference Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 The cleaning assembly includes: a guide block 111, which is slidably mounted on the inner wall of the guide port 10; a one-way bearing 112, which is arranged at the output end of the servo motor 8, and the outer ring of the one-way bearing 112 is fixedly connected to the output end of the servo motor 8, and the locking direction of the one-way bearing 1 97 is opposite to that of the one-way bearing 112; a reciprocating screw 113, which is arranged on the inner ring of the one-way bearing 112, and the guide block 111 is screwed to the reciprocating screw 113; a support rod 114, which is fixedly mounted on the side of the guide block 111; a scraper 115, which is fixedly mounted on the end of the support rod 114; a transmission gear 116, which is movably mounted on the support rod 114; a guide rod 117, which is arranged on the side of the transmission gear 116, and the guide rod 117 is slidably connected to the penetration; a support plate 118, which is fixedly mounted on the guide rod The cleaning roller 119 is rotatably mounted on the end of the support plate 118 away from the guide rod 117; the flip mechanism is arranged on the inner side of the outer frame 1; the servo motor 8 is turned on and reversed, and the servo motor 8 can drive the reciprocating screw 113 to rotate. Since the guide block 111 is screwed with the reciprocating screw 113, the guide block 111 can be driven to slide back and forth along the guide port 10. During the sliding process of the guide block 111, the blood on the top surface of the simulated skin block 4 can be scraped off by the scraper 115, and the scraped blood can be pushed to move along the gap between the outer frame 1 and the fixed frame 2 into the liquid storage tank 71 for standby use, and the top surface of the simulated skin block 4 can be rolled and cleaned by the cleaning roller 119, so that the top surface of the simulated skin block 4 is more tidy for reuse.

[0084] Reference Figure 3 , Figure 6 , Figure 7 , Figure 8The flipping mechanism includes: a fixed rack 1110, fixedly mounted on the inner wall of the outer frame 1 and located below one end of the guide opening 10; a magnet 1111, which is arranged on the side of the transmission gear 116 and is fixedly connected to the penetration; a magnetic sheet 1112, fixedly mounted on the end of the scraper 115, and the magnetic poles of the magnet 1111 and the magnetic sheet 1112 are opposite; a fixed rack 2 1113, fixedly mounted on the inner wall of the outer frame 1 and located below the other end of the guide opening 10 through a fixed frame; a magnetic sheet 2 1114, fixedly mounted on the inner wall of the outer frame 1 and located above the end of the fixed rack 2 1113 , the magnetic poles of magnet 1111 and magnetic sheet 2 1114 are opposite; when guide block 111 moves to the end of guide port 10 away from servo motor 8, transmission gear 116 can mesh with fixed rack 1110, and as guide block 111 continues to move, transmission gear 116 can be driven to rotate, and cleaning roller 119 can be driven to flip through guide rod 117 and support plate 118, so that cleaning roller 119 flips to the other side of scraper 115, ensuring that scraper 115 can be in front and cleaning roller 119 behind when guide block 111 moves for cleaning, and after cleaning roller 119 flips, transmission gear 116 can be driven to rotate, and cleaning roller 119 can be driven to flip to the other side of scraper 115, ensuring that scraper 115 can be in front and cleaning roller 119 can be behind when guide block 111 moves, so as to clean, and after cleaning roller 119 flips, transmission gear The magnet 1111 on the wheel 116 can be opposite to the magnetic sheet 1112. Since the relative magnetic poles of the two are opposite, the transmission gear 116 can slide along the support rod 114 and staggered with the fixed rack 1110 under the action of the attractive magnetic force, so that when the guide block 111 moves in the opposite direction, the cleaning roller 119 will not be flipped again; and when the guide block 111 slides to the other end of the guide port 10, the transmission gear 116 can mesh with the fixed rack 2 1113, thereby driving the cleaning roller 119 to flip in the opposite direction, and after the cleaning roller 119 is flipped, the magnet 1111 can be opposite to the magnetic sheet 2 1114. Since the magnet The magnetic poles of 1111 and the magnetic sheet 2 1114 are also opposite, so under the action of the attractive magnetic force, the transmission gear 116 can slide and reset along the support rod 114 again so as to be used in the next stroke. The fixed rack 1110 and the fixed rack 2 1113 are in staggered positions, so that the transmission gear 116 can be engaged with the fixed rack 1 1110 and the fixed rack 2 1113 at different positions on the support rod 114, respectively. In addition, since the cleaning roller 119 can always fit with the top surface of the simulated skin block 4 and has a certain friction force, the transmission gear 116 can be in a stable state after rotating and sliding along the support rod 114.

[0085] Reference Figure 2 , Fig. 9The tightening assembly includes: a slide groove 131, which is provided on the inner wall of the fixed frame 2; a slider 132, which is fixedly installed on the side of the adjustment plate 12, and the slider 132 is slidably connected with the slide groove 131; two mounting grooves 133, which are respectively provided on the top surfaces of the two adjustment plates 12; two air bags 134, which are respectively arranged on the inner walls of the two mounting grooves 133; two air pipes 135, which are respectively arranged on the two air bags 134; before training, the staff can slide the adjustment plate 12 on the inner wall of the fixed frame 2 through the slide groove 131 and the slider 132 to change the use position, and after the adjustment is completed, the air pipe 135 can be connected with the inflating handball, and the air bag 134 can be inflated by pressing the inflating handball, so that the air bag 134 expands to lift the bottom surface of the supporting tympanic membrane 3 and the simulated skin block 4, so as to simulate the lifting of different organs, and the trainer can start suturing training, and after the training is completed, the inflating handball can be separated from the air pipe 135, and the gas in the air bag 134 can be discharged so that it can be used again.

[0086] The specific working principle of the present invention is as follows:

[0087] When in use, the outer frame 1 can be directly placed on the training table, and then the suturing instrument can be taken out, and suturing practice can be performed by simulating the sutured incision 5 on the skin block 4. If the difficulty needs to be increased during the suturing process, the different positions of the bottom surface of the simulated skin block 4 can be lifted up by the tightening component to simulate the lifting of the organ in the abdomen, making the training more realistic. In addition, during the suturing process, the servo motor 8 can be turned on to rotate forward to simulate the bleeding of the sutured incision 5 through the cooperation of the bleeding component and the driving component, making the training more realistic. After the suturing training is completed, the staff can start the servo motor 8 again to reverse, and then drive the cleaning component to move along the guide port 10 and clean and recover the blood on the simulated skin block 4, so as to perform training again.

[0088] Specifically, before training, the staff can slide the adjustment plate 12 on the inner wall of the fixed frame 2 through the slide groove 131 and the slider 132 to change the use position. After the adjustment is completed, the trachea 135 can be connected to the inflating handball, and the airbag 134 can be inflated by pressing the inflating handball, so that the airbag 134 expands to support the tympanic membrane 3 and the bottom surface of the simulated skin block 4, so as to simulate the lifting of different organs. The trainee can start suturing training, and after the training is completed, the inflating handball can be separated from the trachea 135, and the gas in the airbag 134 can be discharged so that it can be used again. The working principle and connection method of the inflating handball are existing mature technologies, which will not be described in detail here.

[0089] During the suturing training, the staff can turn on the servo motor 8 for forward rotation. Since the locking directions of the one-way bearing 1 97 and the one-way bearing 2 112 are opposite, the servo motor 8 can drive the rotating shaft 95 and the driving bevel gear 96 to rotate through the one-way bearing 1 97, the driven wheel and the synchronous belt when rotating forward, but cannot drive the reciprocating screw 113 to rotate. The driving bevel gear 96 is meshed with the driven bevel gear 94, and then the crankshaft 91 can be driven to rotate. During the rotation of the crankshaft 91, the push plate 76 can be reciprocated by the connecting rod 93 and the push rod 77, so that the push plate 76 It can slide back and forth in the pump liquid chamber 75. Since the return pipe 73 and the outlet pipe 74 are provided with one-way valves with opposite flow directions, the simulated blood in the liquid storage box 71 can be drawn into the liquid guide box 6 through the return pipe 73 during the reciprocating sliding of the push plate 76, and the blood in the pump liquid chamber 75 can be pushed into the outlet pipe 74 to flow out along the suture incision 5, simulating the bleeding during the suture process. At the same time, due to the use of the crankshaft 91 and the installation of several outlet pipes 74 at different positions, the bleeding time of each outlet pipe 74 is different, making the simulation more realistic.

[0090] After the suturing training is completed, the blood flows out and adheres to the simulated skin block 4. At this time, the staff can turn on the servo motor 8 to reverse, and the servo motor 8 can drive the reciprocating screw 113 to rotate. Since the guide block 111 is screwed with the reciprocating screw 113, the guide block 111 can be driven to slide back and forth along the guide port 10. During the sliding process of the guide block 111, the blood on the top surface of the simulated skin block 4 can be scraped off by the scraper 115, and the scraped blood can be pushed to move along the gap between the outer frame 1 and the fixed frame 2 into the liquid storage tank 71 for standby use, and the top surface of the simulated skin block 4 can be rolled and cleaned by the cleaning roller 119, so that the top surface of the simulated skin block 4 is more tidy, so that it can be used again;

[0091] When the guide block 111 moves to the end of the guide opening 10 away from the servo motor 8, the transmission gear 116 can mesh with the fixed rack 1110. As the guide block 111 continues to move, the transmission gear 116 can be driven to rotate, and the cleaning roller 119 can be turned over through the guide rod 117 and the support plate 118, so that the cleaning roller 119 is turned over to the other side of the scraper 115, ensuring that the scraper 115 can be in front and the cleaning roller 119 can be behind when the guide block 111 moves, so as to clean the cleaning roller 119. After the cleaning roller 119 is turned over, the magnet 1111 on the transmission gear 116 can be opposite to the magnetic sheet 1112. Since the relative magnetic poles of the two are opposite, the transmission gear 116 can slide along the support rod 114 and staggered with the fixed rack 1110 under the action of the mutually attractive magnetic force, so that when the guide block 111 moves in the opposite direction, the cleaning roller 119 will not be turned over again.

[0092] When the guide block 111 slides to the other end of the guide opening 10, the transmission gear 116 can mesh with the fixed rack 1113, thereby driving the cleaning roller 119 to flip in the opposite direction. After the cleaning roller 119 is flipped, the magnet 1111 can be opposite to the magnetic piece 1114. Since the magnetic poles of the magnet 1111 and the magnetic piece 1114 are opposite, the transmission gear 116 can slide and reset along the support rod 114 again under the action of the attractive magnetic force so that it can be used in the next stroke. The fixed rack 1110 and the fixed rack 2 1113 are in staggered positions, so that the transmission gear 116 can mesh with the fixed rack 1 1110 and the fixed rack 2 1113 at different positions on the support rod 114, respectively. Moreover, since the cleaning roller 119 can always fit with the top surface of the simulated skin block 4, the transmission gear 116 can be in a stable state after rotating and sliding along the support rod 114.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
