Description

Technical Field

[0001] The invention belongs to the technical field of medical training devices, and in particular relates to a vascular suturing nursing simulation training device. Background Art

[0002] Vascular suturing is a commonly used method of vascular repair in medical surgery. It uses special vascular suture needles and absorbable sutures. The technique and operation of vascular suturing rely on experience. If the suturing effect is not good, it will cause adverse reactions in patients after vascular suturing. In order to ensure rapid learning of vascular suturing during the medical process, special vascular suture nursing simulation training will be set up.

[0003] Although the existing vascular suturing simulation training device can realize the vascular suturing simulation training, the simulation training device simply clamps and fixes the simulated blood vessel on the stage, and then performs suturing training on the clamped simulated blood vessel through surgical instruments. However, since the blood vessels in the real environment are in tissues such as fat and have a certain amount of blood immersed, the existing simulation training device cannot truly simulate the suturing simulation training of the blood vessels in tissues such as fat and with blood flowing inside. This not only limits the training of blood control during the vascular suturing process, but also makes it difficult to simulate the suturing training effect of the blood vessels in a relatively real environment.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention embeds a simulated blood vessel in a simulated silicone layer, and the liquid guide bend pipe injects red liquid into the simulated blood vessel for flow, so as to simulate the blood flow state in the blood vessel for suturing simulation training. The blood vessel clamping mechanism can clamp and fix the part of the simulated blood vessel to be sutured that is peeled off from the simulated silicone layer, and then cut the simulated blood vessel to be sutured, so as to facilitate the trainees to suture the simulated blood vessel under the state of blood flow. At the same time, the water pump in the liquid tank can be controlled to be opened and closed intermittently, so that the simulated blood vessel can simulate the states of contraction, expansion, blood flow velocity, etc., so that the trainees can better experience the dynamic changes of blood vessels in real surgery, thereby improving the authenticity of the simulation training device of the present invention for vascular suturing care simulation training.

[0015] 2. The present invention uses a retractable blood vessel clamping mechanism. The symmetrical splints, driven by the sliding adjustment component, can not only clamp and seal the part of the simulated blood vessel to be sutured to prevent a large amount of red liquid from seeping out of the simulated blood vessel and affecting the simulated blood vessel suture simulation training, but the symmetrical splints can move downward and be inserted into the gap cut in the simulated silicone layer. Then the sliding adjustment component works to make the two symmetrical splints move away from each other, thereby facilitating the leakage of the simulated blood vessel pre-buried in the simulated silicone layer. Then the trainee can take the pre-buried simulated blood vessel out of the cut notch as needed to perform suture simulation training, thereby further simulating the preparation work that the trainee needs to perform before and after blood vessel suturing, thereby better training the suture personnel to perform blood vessel suturing operations accurately and efficiently in a real environment.

[0034] Specifically, the present invention detachably installs the simulated silicone layer 3 in the square frame 2, and pre-buries the simulated blood vessel 4 in the simulated silicone layer 3, so that the simulation personnel can take out the simulated blood vessel 4 from the simulated silicone layer 3 in a relatively realistic environment, and a plurality of liquid guide bends 21 can inject the red liquid in the liquid tank into the simulated blood vessel 4, so as to simulate the blood flow state in the blood vessel for suturing simulation training, and the blood vessel clamping mechanism 5 can clamp and fix the part to be sutured of the simulated blood vessel 4 peeled out from the simulated silicone layer 3, and then cut the simulated blood vessel 4 to be sutured, so as to facilitate the training personnel to suture the simulated blood vessel 4 under the state of blood flow, and at the same time can control the intermittent opening and closing of the water pump in the liquid tank, so that the simulated blood vessel 4 can be contracted. , expansion, blood flow rate and other states, so that the trainee can better experience the dynamic changes of blood vessels in real surgery, and after the simulated blood vessel 4 is sutured, the blood vessel clamping mechanism 5 disengages from the clamping of the simulated blood vessel 4, so that the red liquid in the liquid tank flows in the simulated blood vessel 4 after suturing, and at the same time, the contraction, expansion, blood flow rate and other states of the blood vessel are simulated, so that the trainee can better experience whether there is exudation or leakage after the blood vessel suturing, so as to better simulate the care of the sutured blood vessel, and the mobile swing mechanism 7 can move and swing the blood clamping mechanism so that it can slide to other corresponding simulated blood vessels 4 of the simulated silicone layer 3, clamp and block the simulated blood vessel 4 to be sutured, so as to facilitate the suturing training of the simulated blood vessel 4.

[0035] In the scheme designed by the present invention, the blood vessel clamping mechanism 5 includes a splint 51, a cross block 52, a scissor rod 53, a rotating shaft 54, a torsion spring 55 and a hinged soft rod 56. The two splints 51 are arranged in a mirror image, and each of the top surfaces of the splints 51 is provided with a cross block 52. The two cross blocks 52 are staggered with each other. The upper surface of the cross block 52 is vertically provided with a scissor rod 53. The two scissor rods 53 are connected to each other through a rotating shaft 54 ​​and a torsion spring 55. The tops of the two scissor rods 53 are connected to the sliding adjustment component 6 through a hinged soft rod 56.

[0036] Specifically, through the cooperation of the sliding adjustment component 6 and the hinged soft rod 56, the left and right scissor rods 53 can be in a scissor state, and at this time, the cooperation of the torsion spring 55 and the rotating shaft 54 ​​can make the clamps 51 connected by the horizontal block 52 at the bottom of the two scissor rods 53 close to or away from each other, so as to facilitate the clamping and blocking of the simulated blood vessel 4 taken out from the simulated silicone layer 3, and then the two sets of symmetrical clamps 51 can clamp and block the part of the simulated blood vessel 4 to be cut, so as to prevent the red liquid in the simulated blood vessel 4 from leaking a lot, so as to facilitate training. Personnel can better perform suturing simulation training on the simulated blood vessel 4 with flowing liquid, and the two horizontal blocks 52 are symmetrically connected to the two splints 51, so that they will not interfere with the clamping and blocking of the simulated blood vessel 4 by the symmetrical splints 51, and the scissor rods 53 are connected to the sliding adjustment component 6 through the hinged soft rod 56, so that when the sliding adjustment component 6 slides horizontally back and forth, it will not interfere with the cross-swinging of the scissor rods 53, thereby facilitating the left and right scissor rods 53 to drive the front and rear splints 51 to quickly and accurately clamp and block the part of the simulated blood vessel 4 to be sutured.

[0037] In the solution designed by the present invention, the blood vessel clamping mechanism 5 also includes a rectangular rod 57, a spring member 58 and an electric push rod 59. The bottom of the scissor rod 53 is provided with a square hole upward, and the rectangular rod 57 is slidably inserted in the square hole. The top of the rectangular rod 57 is connected to the top of the square hole through the spring member 58. The electric push rod 59 is vertically fixed to the outside of the scissor rod 53, and the output rod of the electric push rod 59 is connected to the cross block 52.

[0038] Specifically, when it is necessary to take out the simulated blood vessel 4 from the simulated silicone layer 3, the trainer first cuts the corresponding part of the simulated silicone layer 3, and then controls the output rod of the electric push rod 59 vertically fixed on the scissor rod 53 to extend, so that it pushes the cross block 52 to move downward, and the rectangular rod 57 will slide downward in the square hole, and the spring member 58 will be stretched, so that the symmetrical splints 51 can move downward and be inserted into the gap cut in the simulated silicone layer 3, and then the sliding adjustment component 6 works to make the two symmetrical splints 51 move away from each other, so as to facilitate the leakage of the simulated blood vessel 4 pre-buried in the simulated silicone layer 3, and then the trainer takes out the pre-buried blood vessel 4 as needed. The buried simulated blood vessel 4 is taken out from the cut notch for suture simulation training, so as to further simulate the preparatory work that the trainees need to perform before and after the blood vessel suturing, so as to better train the suture personnel to perform the blood vessel suturing operation accurately and efficiently under the real environment; and when the simulated blood vessel 4 is taken out from the simulated silicone layer 3, the output rod of the electric push rod 59 is slowly retracted, the rectangular rod 57 will be retracted and slid upward in the square hole, the spring member 58 will be restored, and then the symmetrically expanded splint 51 will be withdrawn from the simulated silicone layer 3, and then slide to both sides of the simulated blood vessel 4 to be sutured, so as to clamp and block the simulated blood vessel 4 to be sutured.

[0039] In the scheme designed by the present invention, the sliding adjustment component 6 includes an L-shaped block 61, a supporting side plate 62, a double-rotation screw 63, a sliding support block 64, a handle 65 and a limit ring 66. The top of the hinged soft rod 56 is connected to the horizontal block of the L-shaped block 61, and the vertical block side of the L-shaped block 61 is integrally formed with the supporting side plate 62. The supporting side plate 62 on one side corresponds to the vertical block of the L-shaped block 61 corresponding to the other side. The vertical blocks of the symmetrical L-shaped blocks 61 are all provided with screw nuts, and the double-rotation screws 63 are inserted into the symmetrical screw nuts. The middle part of the double-rotation screw 63 is rotated and inserted into the sliding support block 64. The sliding support block 64 is installed on the mobile swing mechanism 7. One end of the double-rotation screw 63 is fixed with a handle 65, and the other end thereof is installed with a limit ring 66.

[0040] Specifically, by rotating the handle 65, it drives the double-rotation screw 63 to rotate, and then the symmetrical L-shaped block 61 will drive the scissor rod 53 to swing through the hinged soft rod 56, so as to facilitate the symmetrical clamping plates 51 to move away from or close to each other, thereby achieving the clamping and blocking of the simulated blood vessel 4; for example, when the vertical blocks of the symmetrical L-shaped block 61 slide synchronously in the direction of the sliding support block 64, the hinged soft rod 56 will drive the scissor rod 53 to swing like a scissor, so that the symmetrical clamping plates 51 will swing away from each other, thereby facilitating the release of the clamping of the simulated blood vessel 4, or facilitating the expansion and opening of the cut part of the simulated silicone layer 3. When the vertical plates of the L-shaped block 61 slide away from each other, the symmetrical clamps 51 will approach each other, which is convenient for clamping and blocking the simulated blood vessel 4. The design of the supporting side plates 62 integrally formed on the side of the L-shaped block 61 facilitates the double-rotation screw 63 to rotate and drive the symmetrical L-shaped blocks 61 to synchronously approach or slide away from each other, which is convenient for scissor swing adjustment of the scissor rods 53 connected by the hinged soft rods 56, thereby further improving the accuracy and efficiency of the clamps 51 in clamping and blocking the simulated blood vessel 4 or expanding the simulated silicone layer 3 of the incision.

[0041] In the scheme designed by the present invention, the mobile swing mechanism 7 includes a semi-circular disc 71, a swing shaft 72, a swing connecting rod 73, a support shaft 74, a roller 75 and a swing square rod 76. The upper surface of the square frame 2 is symmetrically provided with semi-circular discs 71, each of which is provided with a semi-circular through-groove 711. The semi-circular disc 71 is rotatably mounted with a swing shaft 72 through a bearing, and the axis of the swing shaft 72 is the same as the axis of the semi-circular through-groove 711. The swing shaft 72 is fixedly sleeved with a swing connecting rod 73, and a support shaft 74 is rotatably inserted in the semi-circular through-groove 711 through a roller 75. One end of the support shaft 74 is connected to the other end of the swing connecting rod 73, and the inner end of the symmetrical support shaft 74 is connected to the swing square rod 76. The swing square rod 76 is provided with a through-slot 761 that penetrates front and back along its length direction, and a sliding support block 64 is provided in the through-slot 761.

[0042] Specifically, by driving the servo motor fixed on the outer side of the semicircular disk 71, the swing shaft 72 can drive the support shaft 74 to swing in a semicircular state in the semicircular through-groove 711 through the swing connecting rod 73, and then the swing square rod 76 will drive the symmetrical clamping plate 51 to swing through the sliding support block 64, so as to realize the turning over and suturing operation of the clamped and blocked simulated blood vessel 4; for example, when the support shaft 74 drives the swing square rod 76 to slide to the front side groove bottom of the semicircular through-groove 711, the symmetrical clamping plate 51 will flip the clamped and blocked simulated blood vessel 4 to the upper surface of the simulated silicone layer 3, which is convenient for suturing training of the simulated blood vessel 4, and when the support shaft 74 drives the swing square rod 76 to swing to the rear side groove bottom of the semicircular through-groove 711, the clamping plate 51 will drive the simulated blood vessel 4 to flip, and the unsutured part of the simulated blood vessel 4 will leak out, which is convenient for the trainees to continue the vascular suturing training, and because the height of the groove bottom at both ends of the semicircular through-groove 711 is higher than the simulated The upper surface of the silicone layer 3, therefore, when the scissor rod 53 is flipped to a horizontal state, it will not hit the surface of the simulated silicone layer 3, and the simulated blood vessel 4 clamped by the splint 51 will not be unable to be turned over normally and accurately due to the interference of the double-rotation screw 63, the L-shaped block 61 and other structures. At the same time, the swing square rod 76, the scissor rod 53 and the splint 51 and other structures are flipped to a horizontal state. Therefore, it will not interfere with the normal suturing of the simulated blood vessel 4 by the trainees, and it is convenient to quickly flip the simulated blood vessel 4 after suturing, so that the trainees can accurately perform suturing training on the unsutured parts; and when the support shaft 74 drives the swing square rod 76 to swing to the top of the semicircular through-groove 711, the swing square rod 76 will be in the highest state at this time, and the scissor rod 53 and other structures will be in a vertical state, which is convenient for the splint 51 to open or shrink to clamp and block the simulated blood vessel 4, or to quickly expand and open the gap cut on the simulated silicone layer 3.

[0043] In the scheme designed by the present invention, the upper and lower groove walls of the through slide groove 761 are both provided with a limit guide groove 762, and the limit guide groove 762 is insulated with an electromagnetic suction strip 77, the upper and lower surfaces of the sliding support block 64 are insulated with metal suction blocks 67, and the metal suction blocks 67 are in sliding contact with the electromagnetic suction strip 77, and the groove bottoms at both ends of the semicircular through groove 711 are both provided with contact switches 78, and the contacts of the contact switch 78 extend out of the groove bottom of the semicircular through groove 711 through the spring member 58, and the electrical signal of the contact switch 78 is connected to the electromagnetic suction strip 77;

[0044] Specifically, the sliding support block 64 can slide in the through-slot 761 opened on the swinging square rod 76 through the cooperation of the upper and lower metal suction blocks 67, so as to facilitate the adjustment of the distance between the two sets of blood vessel clamping mechanisms 5 on the swinging square rod 76, which is not only convenient for expanding and opening the notches cut at different positions on the simulated silicone layer 3, so that the simulated blood vessels 4 at different positions can be quickly taken out, but also can clamp and block the simulated blood vessels 4 at different positions, thereby facilitating the improvement of the reuse rate of the simulated blood vessels 4. When the sliding support block 64 slides to a suitable position in the through-slot 761, the roller 75 slides to the bottom of the semicircular through-slot 711. At this time, the roller 75 will squeeze the spring member 58, and the electrical signal of the contact switch 78 will control the electromagnetic suction strip 77 to be energized through the control system on the training platform 1, so that the electromagnetic suction strip 77 has a magnetic adsorption force to adsorb and fix the metal suction block 67, thereby preventing the simulated blood vessel from being stuck. During suturing, the sliding support block 64 freely slides on the swinging square rod 76, thereby affecting the accuracy and stability of suturing the simulated blood vessel 4 during simulation training. When the roller 75 slides to the highest position of the semicircular through-groove 711, the contact switch 78 is closed, and the electromagnetic suction strip 77 is powered off and loses its magnetic adsorption force, thereby facilitating the sliding support block 64 to freely slide in the through-groove 761, and adjusting the two sets of symmetrical clamping plates 51 to achieve the removal, clamping and blocking of the simulated blood vessel 4 at different positions. The cooperation of the spring member 58 provided on the contact switch 78 and the roller 75 can not only reduce the wear of the support shaft 74 in the semicircular through-groove 711, but also play a buffering and protective role for the support shaft 74, preventing the support shaft 74 from directly hitting the bottom of the semicircular through-groove 711 and shaking, thereby affecting the stability and safety of the symmetrical clamping plates 51 clamping the simulated blood vessel 4.

[0045] In the scheme designed by the present invention, the mobile swing mechanism 7 also includes a mobile long rod 79, a mobile block 80, a transmission screw 81 and a support ear block 82. The outer side surface of the semi-circular disk 71 is provided with at least two mobile long rods 79, and the outer end of the mobile long rod 79 is connected to the mobile block 80. The transmission screw 81 is inserted into the mobile block 80 through a screw nut. The training platform 1 is symmetrically provided with support ear blocks 82, and the transmission screw 81 is rotatably arranged on the support ear block 82 through a bearing. A servo motor is fixed on the outer side surface of one of the support ear blocks 82. , and the output shaft of the servo motor is connected to the transmission screw 81; specifically, through the driving of the servo motor fixed on the outer side of the supporting ear block 82, the transmission screw 81 drives the moving block 80 to slide horizontally back and forth on the upper surface of the training platform 1, and then drives the symmetrical semi-circular disks 71 to slide back and forth on the square frame 2 through the moving long rod 79, so as to facilitate the adjustment of the positions of the two groups of blood vessel clamping mechanisms 5 on the simulated silicone layer 3, so that it can remove, clamp and block the multiple simulated blood vessels 4 pre-buried in the simulated silicone layer 3, thereby further improving the utilization rate of the simulation training device.

[0046] In the design of the present invention, two sets of guide rail assemblies 83 are fixedly provided on the upper surface of the square frame 2, and the sliders of the guide rail assemblies 83 are connected to the semi-circular disc 71; specifically, the design of the guide rail assemblies 83 can play a guiding and supporting role for the semi-circular disc 71 sliding back and forth, thereby preventing the semi-circular disc 71 from tilting when sliding on the square frame 2.
