Description

Technical Field

[0001] The present invention relates to the technical field of neurointervention simulation, and in particular to a neurointervention surgery simulation simulator. Background Art

[0002] Neurointerventional surgery is a procedure that uses an intravascular catheter to dilate, remove, and deliver drugs to blocked blood vessels. Neurointerventional surgery is widely used in the treatment of ischemic or hemorrhagic cerebrovascular disease, cerebral aneurysm, brain and spinal vascular disease, brain tumors, spinal tumors and other diseases because of its minor trauma and quick recovery.

[0003] Since neurointerventional surgery is difficult to perform, simulation operations are usually required before the formal surgery. However, existing simulation devices are relatively simple, and usually only blood vessels are set up, and then catheters are operated in the blood vessels for simulation operations, such as removing blood clots. However, during the actual operation, the blood vessels are inserted with catheters, and the blood flowing in the patient's blood vessels is not constant. For example, during the operation of the nerve catheter, the patient may experience arrhythmia. Once the patient has arrhythmia, the blood flow in the blood vessels will change irregularly. How to standardize the operation of neurointerventional surgery at this time is impossible to simulate with existing simulation simulators. This results in the existing simulators being relatively simple in simulation and the simulation effect is poor. At the same time, the simulated blood in the existing simulators usually does not have a disinfection mechanism. When the simulator is used for a long time, microorganisms and bacteria usually grow inside the simulated blood. If these microorganisms and bacteria are not disinfected, the microorganisms and bacteria growing in the simulated blood will change the fluidity of the simulated blood, and the normal blood flow effect cannot be simulated, thereby affecting the simulation effect of the surgical simulation simulator.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Fig.10A neurointerventional surgery simulation simulator comprises a base plate 1, a simulated blood vessel 2 is arranged on the base plate 1, a plurality of protrusions 3 are arranged on the simulated blood vessel 2, the bottoms of the plurality of protrusions 3 are fixedly connected to the outer wall of the base plate 1, a pluggable catheter insertion port 4 is arranged on the simulated blood vessel 2, and a blood flow simulation mechanism is arranged outside the base plate 1; the blood flow simulation mechanism comprises a base 7 arranged on the base plate 1, a suction cylinder 8 is fixedly connected to the outer wall of the base 7, connecting ports 9 are arranged on both sides of the suction cylinder 8, the connecting ports 9 on both sides are connected to the two ends of the simulated blood vessel 2, and one-way valves are arranged inside the connecting ports 9 on both sides.

[0031] A mounting plate 5 is fixedly connected to the outer wall of the bottom plate 1 , a starting motor 6 is fixedly connected to the outer wall of the mounting plate 5 , a transmission rod 14 is arranged at the output end of the starting motor 6 , and a turntable 10 is arranged at the end of the transmission rod 14 .

[0032] A plurality of slide grooves 11 are provided on the turntable 10, and knocking rods 12 are slidably connected inside the plurality of slide grooves 11. The plurality of knocking rods 12 have different lengths, and a pressing spring 13 is fixedly connected to the outer wall of the plurality of knocking rods 12, and the other end of the pressing spring 13 is fixedly connected to the outer wall of the turntable 10.

[0033] A disc 16 is slidably connected to the outer wall of the transmission rod 14 , and a plurality of lifting members 17 are arranged on the outer wall of the disc 16 . The ends of the plurality of lifting members 17 are all located inside the corresponding slide grooves 11 , and a contact magnet 18 is fixedly connected to the outer wall of the disc 16 .

[0034] A slide rail 21 is provided inside the mounting plate 5, and a pressure plate 19 is slidably connected to the inner wall of the slide rail 21. One end of the pressure plate 19 away from the inside of the slide rail 21 is fixedly connected to the top of the suction cylinder 8. A return spring 22 is provided on the inner wall of the slide rail 21, and the other end of the return spring 22 contacts the outer wall of the pressure plate 19. A pressing magnet 20 is provided on the pressure plate 19, and the magnetic poles of the pressing magnet 20 are the same as those of the contact magnet 18.

[0035] In this embodiment, when in use, the operator can turn on the starting motor 6, so that it drives the disc 16 to rotate through the telescopic rod 15. When the disc 16 rotates, it will drive the contact magnet 18 to be intermittently located directly above the pressing magnet 20. Under the combined action of the intermittent magnetic force of the two and the elastic force of the return spring 22, the pressure plate 19 will press the suction cylinder 8 reciprocatingly up and down. When the suction cylinder 8 is pressed reciprocatingly, the simulated blood in the simulated blood vessel 2 will be sucked into the interior through the end of the simulated blood vessel 2, and then discharged into the simulated blood vessel 2 through the end of the simulated blood vessel 2 on the other side, thereby realizing the normal circulation of the simulated blood in the simulated blood vessel 2. At this time, the operator can insert a catheter into the simulated blood vessel 2 through the catheter insertion port 4 to simulate the neurointervention operation under normal circumstances.

[0036] When the user performs a neurointervention operation in the simulated blood vessel 2 through the catheter insertion port 4, the telescopic rod 15 can also be extended. When the telescopic rod 15 is extended, it will push the multiple lifting members 17 to be inserted into the corresponding slide groove 11. When the multiple lifting members 17 are inserted into the corresponding slide groove 11, the contact bevel of the lifting member 17 will push out the knocking rod 12 inside the slide groove 11, so that it moves to the outside of the turntable 10. The multiple knocking rods 12 moving to the outside of the turntable 10 will intermittently knock and press the top of the suction cylinder 8 as the turntable 10 rotates. Since the lengths of the multiple knocking rods 12 are different, The knocking amplitude of the suction cylinder 8 is also different. When the suction cylinder 8 is subjected to irregular knocking and pressing, the suction cylinder 8 will perform irregular pumping with the elastic force of the reset spring 22. At this time, the suction cylinder 8 will become irregular when circulating and sucking the simulated blood in the simulated blood vessel 2, thereby causing irregular changes in the simulated blood flow in the simulated blood vessel 2, simulating arrhythmia and irregular blood flow. At this time, it will be more difficult for the user to perform neurointervention operations in the simulated blood vessel 2 than in normal situations. By simulating abnormal situations, the entire simulation device can be made more realistic.

[0037] Example 2: Please refer to Figure 1 - Fig.10 This embodiment further illustrates the first embodiment. A liquid storage tank 24 is fixedly connected to the outer wall of the transmission rod 14. The liquid storage tank 24 is provided with a liquid filling port. A telescopic rod 15 is provided on the liquid storage tank 24. The end of the telescopic rod 15 is fixedly connected to the disc 16.

[0038] A covering ring 25 is provided on the mounting plate 5, and a disinfection tube 41 is provided inside the covering ring 25. One end of the disinfection tube 41 away from the covering ring 25 is connected to the interior of the suction cylinder 8. The disinfection tube 41 is slidably connected to the pressure plate 19. A plurality of fixing members 23 are fixedly connected to the outer wall of the covering ring 25. The plurality of fixing members 23 are all fixedly connected to the outer wall of the mounting plate 5. The covering ring 25 is rotatably connected to the liquid storage tank 24, and a disinfection mechanism is provided on the liquid storage tank 24.

[0039] The disinfection mechanism includes a plurality of liquid-throwing tubes 31 connected and arranged inside the liquid storage tank 24. An upper magnetic ring 34 is slidably connected to the outer walls of the plurality of liquid-throwing tubes 31. A connecting rod 33 is fixedly connected to the outer wall of the upper magnetic ring 34. A lower ring 32 is arranged at the end of the connecting rod 33. A plurality of liquid inlet holes 36 are opened on the liquid-throwing tubes 31. Restoration springs 35 are arranged on both sides of the top end of the liquid-throwing tubes 31. The other end of the restoring spring 35 contacts the outside of the upper magnetic ring 34.

[0040] A nozzle 27 is provided inside the covering ring 25, and a push rod 30 is slidably connected to the inner wall of the nozzle 27. A pressure spring 29 is sleeved on the push rod 30, and a trigger magnet is provided at the end of the push rod 30. The magnetic pole of the trigger magnet is the same as that of the upper magnetic ring 34. The interior of the nozzle 27 is respectively connected to an air injection pipe 26 and an air extraction pipe 28, and both the air injection pipe 26 and the air extraction pipe 28 are provided with a one-way valve.

[0041] A pressing ring 37 is sleeved on the outer wall of the simulated blood vessel 2, an air bag 40 is arranged inside the pressing ring 37, the end of the jet tube 26 away from the nozzle 27 is connected to the inside of the air bag 40, an exhaust port 39 is arranged inside the air bag 40, and a plurality of pressing rods 38 are arranged on the air bag 40.

[0042] In this embodiment, when the simulated blood in the simulated blood vessel 2 is used for a long time and needs to be disinfected, the operator can increase the power of the starting motor 6 to drive the liquid storage tank 24 to rotate at a relatively fast speed through the transmission rod 14. When the liquid storage tank 24 rotates quickly, the centrifugal force generated at this time will cause the upper magnetic ring 34 to overcome the elastic force of the return spring 35 and move a short distance to the outside of the liquid ejection tube 31. When the upper magnetic ring 34 moves a short distance to the outside of the liquid ejection tube 31, the liquid inlet hole 36 blocked by it will leak out (refer to Figure 8 ), when the liquid inlet hole 36 leaks out, the liquid storage tank 24 rotates, and the disinfectant entering the liquid throwing pipe 31 will be thrown into the inside of the covering ring 25 through the multiple leaking liquid inlet holes 36, and finally enter the suction cylinder 8 through the transportation of the disinfection tube 41. The disinfectant entering the suction cylinder 8 will be mixed with the simulated blood when the suction cylinder 8 pumps the simulated blood in the simulated blood vessel 2, so as to disinfect the simulated blood, ensure the fluidity of the simulated blood, and ensure the simulation effect of the entire simulation device.

[0043] If it is necessary to simulate the situation when the blood vessel is squeezed by the tumor, the operator can increase the power of the starting motor 6 again, so that it drives the liquid storage box 24 to rotate at a high speed through the transmission rod 14. When the liquid storage box 24 rotates at a high speed, under the action of a large centrifugal force, the upper magnetic ring 34 and the lower ring 32 overcome the elastic force of the return spring 35 and move to the top side of the liquid ejection tube 31. When the upper magnetic ring 34 and the lower ring 32 move to the top side of the liquid ejection tube 31, the lower ring 32 will replace the upper magnetic ring 34 to block the liquid inlet hole 36 (refer to Fig. 9), when the liquid inlet hole 36 is blocked, the liquid ejection tube 31 will not transport disinfectant into the sheathing ring 25. The upper magnetic ring 34 located at the top of the liquid ejection tube 31, when the liquid storage tank 24 intermittently rotates to the positive side of the trigger magnet located at the top of the push rod 30, under the combined action of the intermittent magnetic force of the two and the elastic force of the pressure spring 29, the push rod 30 will perform reciprocating suction movement in the spray barrel 27. When the push rod 30 performs reciprocating suction movement in the spray barrel 27, the exhaust pipe 28 will suck external air into the spray barrel 27, and then spray it into the airbag 40 through the jet pipe 26, so that the airbag 40 can expand. When the airbag 40 expands, it will push multiple pressing rods 38 to squeeze the simulated blood vessel 2, thereby simulating the situation where the blood vessel is squeezed by the tumor. By simulating three different situations, the user can perform neurointervention operations, which can allow medical staff to repeatedly contact and practice response strategies, thereby improving the medical staff's responsiveness to emergency situations.

[0044] It should be noted that a one-way valve is provided inside the disinfection tube 41 to prevent the simulated blood from flowing back through the disinfection tube 41 when the suction tube 8 is pumping the simulated blood. When the upper magnetic ring 34 moves toward the end of the return spring 35, the liquid inlet hole 36 will leak out for a moment. The momentary leakage of the liquid inlet hole 36 will drip out a small amount of disinfectant, which will not affect the simulated blood when a small amount of disinfectant enters.

[0045] It should be noted that the simulated blood in the simulated blood vessel 2 flows at a relatively slow rate when the suction cylinder 8 is pumped normally or abnormally to simulate blood flow. Therefore, the simulated blood in the simulated blood vessel 2 will not leak out through the catheter insertion port 4. When the starter motor 6 is started at high power to inflate the airbag 40 or to disinfect the simulated blood, the suction cylinder 8 will pump rapidly. At this time, the simulated blood in the simulated blood vessel 2 flows at a faster rate. At this time, the operator can insert a blocking plug on the catheter insertion port 4 to prevent the simulated blood from leaking out.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
