Abstract
Description
Technical Field
[0001] This utility model relates to the field of clinical teaching auxiliary technology in the medical field, specifically a vascular plaque rotary excision training simulation device. Background Technology
[0002] Vascular plaques, primarily referring to atherosclerotic plaques, are a major cause of arterial stenosis and vascular blockage. If a plaque ruptures, it can worsen the blockage, leading to serious conditions such as acute cerebral infarction or acute myocardial infarction, severely threatening the patient's life and health. The harm caused by plaques in the arterial system is significant. Plaque formation is related to lipid and platelet aggregation, as well as the deposition of metabolic waste, and can be induced by factors such as abnormal blood lipids and unhealthy habits. If a plaque ruptures, it may worsen the blockage, triggering acute cerebral infarction or acute myocardial infarction, posing a significant threat to the patient's life and health.
[0003] Currently, treatment options for vascular plaques include drug therapy, interventional therapy, and surgical treatment. Among these, interventional therapy has become a popular treatment method due to its minimal invasiveness and good efficacy. In interventional therapy, plaque excision technology is widely used in the treatment of vascular plaques because it can efficiently remove plaques, reduce the dosage of plaque-removing drugs, and decrease the risk of bleeding.
[0004] Most existing vascular plaque excision techniques typically consist of a catheter, a drive shaft, and a cutting blade. The catheter is inserted into the vascular lesion site, and the drive shaft is connected to an external drive device that enables the blade to rotate at high speed to excise the vascular plaque. However, doctors generally only operate the instruments required for vascular plaque excision during surgery, which prevents them from achieving a high level of proficiency and thus affects the effectiveness of vascular plaque excision.
[0005] Therefore, this invention provides a vascular plaque rotary cutting training simulation device to solve the above problems. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] This invention provides a vascular plaque rotary cutting training simulation device, which aims to solve the problems mentioned in the background art.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, the present invention provides the following technical solution: a vascular plaque rotary cutting training simulation device, comprising a training base plate, an adjustment mechanism installed on the upper surface of the training base plate, and a simulation mechanism installed on one side of the upper surface of the training base plate;
[0010] The adjustment mechanism includes guide grooves arranged in a path array on the upper surface of the training base plate. A sliding rod is slidably connected inside the guide groove. One end of the sliding rod is fixedly connected to a mounting block. Magnet blocks are fixedly connected to both sides of the lower surface of the mounting block. The magnet blocks are in contact with the training base plate. A hollow tube is fixedly connected to one side of the mounting block. A retaining spring is fixedly connected in a ring array inside the hollow tube. Two corresponding arc-shaped clamping plates are fixedly connected to the opposite sides of several retaining springs. The arc-shaped clamping plates correspond to the hollow tube.
[0011] As a preferred technical solution of this application, the mounting block and the hollow tube are slidably connected to the training base plate via a sliding rod, and a snap-fit block is fixedly connected to the other side of the upper surface of the training base plate, with a simulated blood vessel snapped into the inside of the snap-fit block.
[0012] As a preferred technical solution of this application, the simulation mechanism includes a liquid storage box fixedly connected to one side of the upper surface of the training base plate, an inlet pipe fixedly connected to the upper surface of the liquid storage box, a water pump fixedly connected to one side of the liquid storage box, and a connecting pipe fixedly connected to the input end of the water pump, the connecting pipe being connected to the liquid storage box.
[0013] As a preferred technical solution of this application, the simulated blood vessel includes a blood vessel module connected to the output end of a water pump and formed by printing transparent silicone using 3D printing technology. The surface of the blood vessel module is fitted with a receiving tube made of medical silicone material.
[0014] As a preferred technical solution of this application, one end of the receiving tube is snapped into the inside of the snap-fit block, the other end of the receiving tube is fixedly connected to the output end of the water pump, a plaque filler is fixedly connected inside the vascular module, the plaque filler is used to simulate plaque in blood vessels, and the vascular module is inserted into the inside of several arc-shaped clamping plates.
[0015] As a preferred technical solution of this application, the simulation mechanism further includes a storage groove opened at one edge of the upper surface of the training base plate. The storage groove is provided with a vascular plaque cutting device. The vascular plaque cutting device includes a control handle disposed inside the storage groove, a catheter disposed on one side of the control handle, and a cutting blade disposed inside the catheter.
[0016] (III) Beneficial Effects
[0017] By adjusting the structure, the vascular module is inserted between the arc-shaped clamping plates. The vascular module is limited by the snap-fit block and the water pump. The sliding mounting block moves the arc-shaped clamping plate and the vascular module to different positions, allowing the vascular module to form different shapes. This allows the vascular module to simulate the complex course of blood vessels inside the human body, making the simulation of blood vessels more realistic. The water pump delivers blood product simulation material from the reservoir to the inside of the vascular module, and the flow rate of the blood product simulation material can be adjusted to simulate the internal conditions of blood vessels more realistically. This allows doctors to get closer to real blood vessels during training, making them more familiar with the instruments needed for vascular plaque excision and making the operation more convenient.
[0018] By setting up simulation and adjustment mechanisms, after adjusting the direction of the blood vessel, the plaque filler is used to simulate the vascular plaque inside the blood vessel. By inserting catheters and rotary cutting blades into the blood vessel module, the plaque filler is rotary cut, allowing doctors to experience more realistic vascular plaque cutting and improving the effectiveness of doctor training.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This invention provides a vascular plaque excision training simulation device, such as... Figures 1-4 As shown, the vascular plaque rotary cutting training simulation device includes a training base plate 1. An ultrasound diagnostic device is fixedly connected to one side of the training base plate 1, and a snap-fit block 9 is fixedly connected to the other side of the upper surface of the training base plate 1. A simulated blood vessel is snapped into the snap-fit block 9. An adjustment mechanism is installed on the upper surface of the training base plate 1. The adjustment mechanism includes guide grooves 2 arranged in a path array on the upper surface of the training base plate 1. A sliding rod 3 is slidably connected inside the guide grooves 2. A mounting block 4 is fixedly connected to one end of the sliding rod 3. By sliding the sliding rod 3, the mounting block 4 is moved synchronously, so that the hollow tube 6 and the arc-shaped clamping plate 8 move synchronously, which in turn moves the vascular module 10. The position of different parts of the vascular module 10 is adjusted, so that the vascular module 10 bends and forms different waveforms.
[0027] Magnet blocks 5 are fixedly connected to both sides of the lower surface of the mounting block 4. The magnet blocks 5 are attached to the training base plate 1. With the setting of the magnet blocks 5, after the position of the sliding rod 3 is adjusted, the magnet blocks 5 are magnetically attracted to the training base plate 1, limiting the sliding rod 3, thereby making the blood vessel module 10 more stable when simulating blood vessels.
[0028] A hollow tube 6 is fixedly connected to one side of the mounting block 4. The mounting block 4 and the hollow tube 6 are slidably connected to the training base plate 1 through the sliding rod 3. The hollow tube 6 has a ring array of fixedly connected clamping springs 7 inside. By setting the clamping springs 7, when blood product simulation material is injected into the blood vessel module 10, the arc-shaped clamping plate 8 can adapt to blood vessel modules 10 of different diameters.
[0029] Several clamping springs 7 are fixedly connected to two corresponding arc-shaped clamping plates 8 on opposite sides. Before the doctor's training, the blood vessel module 10 is inserted into the inside of the two arc-shaped clamping plates 8 to clamp the blood vessel module 10. At the same time, the two ends of the blood vessel module 10 are respectively connected to the output end of the water pump 13 and the snap-fit block 9.
[0030] The arc-shaped clamping plate 8 corresponds to the hollow tube 6. A simulation mechanism is installed on one side of the upper surface of the training base plate 1. The simulation mechanism includes a liquid storage box 11 fixedly connected to one side of the upper surface of the training base plate 1. An inlet pipe 12 is fixedly connected to the upper surface of the liquid storage box 11. A water pump 13 is fixedly connected to one side of the liquid storage box 11. The simulated blood vessel includes a blood vessel module 10 that is connected to the output end of the water pump 13 and is formed by printing transparent silicone using 3D printing technology. A receiving tube 19 made of medical silicone material is sleeved on the surface of the blood vessel module 10. One end of the receiving tube 19 is snapped into the inside of the snap-fit block 9. The other end of the receiving tube 19 is fixedly connected to the output end of the water pump 13. A plaque filler 15 is fixedly connected inside the blood vessel module 10. When the water pump 13 is started, its input end delivers the blood product simulation material inside the liquid storage box 11 to the inside of the blood vessel module 10 to simulate blood in the blood vessel. The plaque filler 15 simulates blood vessel plaque.
[0031] The plaque filler 15 is used to simulate plaque in blood vessels. The blood vessel module 10 is inserted into the interior of several arc-shaped clamping plates 8. The input end of the water pump 13 is fixedly connected to a connecting pipe 14, which is connected to the reservoir 11. The simulation mechanism also includes a storage slot 16 located at one edge of the upper surface of the training base plate 1. The storage slot 16 is equipped with a blood vessel plaque cutting device. The blood vessel plaque cutting device includes a control handle 17 located inside the storage slot 16, a catheter 18 located on one side of the control handle 17, and a cutting blade located inside the catheter 18. After the doctor cuts the blood vessel module 10, he inserts the catheter 18 and the cutting blade into the interior of the blood vessel module 10, confirms the position of the plaque filler 15 with an ultrasound diagnostic device, and cuts the plaque filler 15 with the cutting blade.
[0032] Specifically, when using this vascular plaque excision training simulation device: before training, the doctor inserts the vascular module 10 into the inside of the two arc-shaped clamping plates 8 to clamp the vascular module 10. At the same time, the two ends of the vascular module 10 are respectively connected to the output end of the water pump 13 and the snap-fit block 9. By sliding the sliding rod 3, the mounting block 4 moves synchronously, so that the hollow tube 6 and the arc-shaped clamping plate 8 move synchronously, which drives the vascular module 10 to move. Adjusting the position of different parts of the vascular module 10 makes the vascular module 10 bend and form different waveforms, so that the vascular module 10 can simulate a more realistic vascular course.
[0033] After the vascular module 10 is placed, the water pump 13 is started, so that the blood product simulation material inside the reservoir 11 is delivered to the inside of the vascular module 10 through its input end to simulate blood in the blood vessels. By setting the plaque filler 15, the vascular plaque is simulated. After the doctor cuts open the vascular module 10, the catheter 18 and the rotary cutting blade are inserted into the inside of the vascular module 10. The position of the plaque filler 15 is confirmed by the ultrasound diagnostic device, and the plaque filler 15 is cut by the rotary cutting blade, thereby achieving the effect of doctor training. Moreover, the training effect of doctors is improved through realistic simulation.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
