Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical teaching tools, in particular to a micro-anastomosis surgery training model. Background Art
[0002] Microsurgery is a surgical technique that uses special, delicate instruments and materials under a surgical microscope to perform minor repairs and reconstructions on small blood vessels, nerves, and other tissues. It is characterized by minimal trauma, high surgical quality, and an expanded scope of surgery, enabling operations that cannot be performed directly with the naked eye. The most common of these is microvascular anastomosis. Microvascular anastomosis is an essential skill for doctors in trauma surgery, hand surgery, maxillofacial and plastic surgery, and reconstructive surgery. It is a necessary condition for the survival of replanted fingers (limbs), thumb reconstruction, and the survival of free flap transplants. However, to master microvascular anastomosis technology, systematic and long-term surgical training is necessary to meet clinical requirements. Currently, most well-known medical schools have launched training courses in microsurgery.
[0003] Current microvascular anastomosis technology training mainly focuses on suturing small rubber sheets and silicone tubes in the early stages, which has poor simulation. Later animal training focuses on rat tail arteries, rabbit ears, and inguinal blood vessels, but there are also problems such as animal ethics, high training costs, and complex implementation process. Utility Model Content
[0004] The purpose of the utility model is to provide a microsurgery training model to solve the above-mentioned technical problems.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a micro-anastomosis surgery training model, comprising a simulation model, a top cover installed on the top of the simulation model, a pressure monitor, a liquid storage tank, a circulation pump, a flow meter and a pressure sensor fixedly installed inside the simulation model, the pressure monitor, liquid storage tank, circulation pump and flow meter are commonly connected to a blood simulation pipeline, a blood vessel model is detachably installed between the two ends of the blood simulation pipeline, the blood vessel model is fitted on the top of the pressure sensor, the circulation pump is located on the top of the liquid storage tank, the input end of the circulation pump is connected to the inside of the liquid storage tank, and the output end of the circulation pump is connected to the blood simulation pipeline.
[0006] Preferably, both ends of the blood vessel model are provided with mounting plates, a slider is fixedly installed on the side of the mounting plate away from the blood vessel model, a limiting plug is fixedly installed on the end of the slider away from the mounting plate, and both ends of the blood simulation pipeline are fixedly provided with connecting plates, a socket and a limiting slide rail are opened through the surface of the connecting plate, the socket is connected to the limiting slide rail, the limiting plug is slidably sleeved on the inner wall of the socket, the slider is slidably sleeved on the inner wall of the limiting slide rail, and the connecting plate is sealed and fit with the surface of the mounting plate.
[0007] Preferably, a slot is provided in the concave portion of the top of the simulation model, a sealing strip is movably inserted into the inner wall of the slot, the sealing strip is fixedly mounted on the bottom of the top cover, the bottom of the top cover is fitted onto the top of the simulation model, the surface of the top cover is detachably sleeved with transparent silicone, the surface of the transparent silicone is penetrated by an opening, and the opening is located above the blood vessel model.
[0008] Compared with related technologies, the microsurgery training model provided by the present invention has the following beneficial effects:
[0009] The utility model provides a micro-anastomosis surgery training model. By installing a blood vessel model between the two ends of a blood simulation pipeline, the blood simulation pipeline forms a closed loop. The circulation pump is started to pump the liquid inside the liquid storage tank into the blood simulation pipeline. The liquid flows through the blood vessel model, the pressure monitor, and the flow meter in sequence and finally returns to the liquid storage tank, thereby achieving the effect of simulating blood circulation. When anastomosis operation practice is required, the blood vessel model is cut open. At this time, the flowing liquid inside the blood vessel model gushes out, and the pressure monitor and the flow meter monitor the pressure of the flowing liquid inside the blood simulation pipeline. When the wound on the blood vessel model is anastomosed, the pressure sensor monitors the trainee. When the anastomosis instrument contacts the sensing part of the pressure sensor or the pressure is too heavy, it represents an operation error, thereby providing good feedback effect, enabling the device to more intuitively display the training results, and allowing trainees in clinical operation training to experience a real environment and quickly master the surgical process, which is of significant significance.
[0010] The utility model provides a micro-anastomosis surgery training model. After the training is completed, the mounting plate is twisted to make the slider slide on the inner track of the limit slide rail. When the limit plug moves to align with the socket position, the mounting plate can be removed by pulling the limit plug out of the socket. Then, a new blood vessel model is replaced and the mounting plate is sealed and fitted with the connecting plate again to complete the replacement of the blood vessel model, thereby continuing to maintain the closed-circuit circulation of the blood simulation pipeline, making the replacement of the blood vessel model more convenient and effectively improving the training efficiency.

[0017] See also Figure 1-Figure 5 The utility model provides a technical solution, including a simulation model 1, a top cover 11 is installed on the top of the simulation model 1, a pressure monitor 2, a liquid storage tank 14, a circulation pump 16, a flow meter 17 and a pressure sensor 18 are fixedly installed inside the simulation model 1, the pressure monitor 2, the liquid storage tank 14, the circulation pump 16 and the flow meter 17 are commonly connected to a blood simulation pipeline 21, a blood vessel model 19 is detachably installed between the two ends of the blood simulation pipeline 21, the blood vessel model 19 is fitted on the top of the pressure sensor 18, the circulation pump 16 is located on the top of the liquid storage tank 14, the input end of the circulation pump 16 is connected to the inside of the liquid storage tank 14, and the output end of the circulation pump 16 is connected to the blood simulation pipeline 21;
[0018] By installing the blood vessel model 19 between the two ends of the simulated blood line 21, the simulated blood line 21 forms a closed loop. The circulating pump 16 is activated to pump the liquid inside the liquid reservoir 14 into the simulated blood line 21. The liquid flows sequentially through the blood vessel model 19, the pressure monitor 2, the flow meter 17, and finally returns to the liquid reservoir 14, achieving the effect of simulating blood circulation. When anastomosis operation is required, the blood vessel model 19 is cut open, and the flowing liquid inside the blood vessel model 19 gushes out. The pressure of the liquid flowing inside the simulated blood line 21 is monitored by the pressure monitor 2 and the flow meter 17. When the wound in the blood vessel model 19 is anastomosed, the pressure sensor 18 monitors the trainee. When the anastomosis instrument contacts the sensing area of the pressure sensor 18 or the pressure is too high, it indicates an operational error. This can provide good feedback, allowing the device to more intuitively display training results, allowing trainees in clinical operation training to experience a real environment and quickly master the surgical process, which is of great significance.
[0019] Both ends of the blood vessel model 19 are provided with mounting plates 28. A slider 29 is fixedly mounted on the side of the mounting plate 28 away from the blood vessel model 19. A limit plug 3 is fixedly mounted on the end of the slider 29 away from the mounting plate 28. Both ends of the blood simulation pipeline 21 are fixedly provided with connecting plates 25. A socket 26 and a limit rail 27 are formed through the surface of the connecting plate 25. The socket 26 is connected to the limit rail 27. The limit plug 3 is slidably mounted on the inner wall of the socket 26. The slider 29 is slidably mounted on the inner wall of the limit rail 27. The connecting plate 25 and the mounting plate 28 are sealed and fitted together.
[0020] After the training is completed, twist the mounting plate 28 so that the slider 29 slides along the internal track of the limiting slide rail 27. When the limiting plug 3 moves to align with the position of the socket 26, the mounting plate 28 can be removed by pulling the limiting plug 3 out of the socket 26. Then, a new vascular model 19 is replaced and the mounting plate 28 is re-sealed with the connecting plate 25 to complete the replacement of the vascular model 19, thereby continuing to maintain the closed-circuit circulation of the blood simulation pipeline 21, making the replacement of the vascular model 19 more convenient and effectively improving the training efficiency.
[0021] A slot 23 is formed in the concave portion of the top of the simulation model 1. A sealing strip 24 is movably inserted into the inner wall of the slot 23. The sealing strip 24 is fixedly mounted on the bottom of the top cover 11. The bottom of the top cover 11 is fitted on the top of the simulation model 1. A transparent silicone rubber 12 is detachably mounted on the surface of the top cover 11. An opening 13 is formed through the surface of the transparent silicone rubber 12. The opening 13 is located above the blood vessel model 19.
[0022] The opening 13 allows the trainee to directly perform anastomosis operations on the blood vessel model 19. When it is necessary to clean the interior of the simulation model 1 or add replacement liquid to the liquid storage tank 14, the top cover 11 can be directly removed. During use, the simulation model 1 and the top cover 11 are kept tightly connected by the insertion of the slot 23 and the sealing strip 24, which effectively improves the practicality of the device.
