Description

Technical Field

[0001] This utility model relates to the field of vascular interventional surgery training equipment, and in particular to a vascular interventional surgery training device. Background Technology

[0002] In the field of vascular interventional surgery, doctors need to master the precise manipulation of guidewires and catheters in complex vascular pathways through repeated training. Traditional training methods rely on animal experiments or cadaver dissections, but these methods have problems such as ethical controversies, high costs, and significant differences between vascular structures and real human bodies. With the development of medical technology, vascular interventional surgery training devices have gradually become an important tool for doctors' skills training. When simulating vascular pathways, vascular interventional surgery training devices often use a fixed structure, which cannot flexibly adjust the bending state of the guidewire, thus limiting the authenticity and effectiveness of the training.

[0032] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please refer to Figures 1 to 4 This utility model provides a vascular interventional surgery training device, including a base 1, a guidewire 4, a catheter 8, a simulated blood vessel 3, a fixing plate 2, a fixing rod, a lateral adjustment component 5, and a longitudinal adjustment component 6;

[0034] The simulated blood vessel 3 is fixed to the base 1 by a support rod;

[0035] The fixing plate 2 is disposed at one end of the base 1;

[0036] One end of the guidewire 4 is fixedly connected to the fixing plate 2, and the other end of the guidewire 4 passes through the simulated blood vessel 3 and is connected in sequence to the horizontal adjustment component 5 and the vertical adjustment component 6;

[0037] The fixing rod is located at the outlet of the simulated blood vessel 3, and one end of the fixing rod is fixedly connected to the base 1. The middle part of the guide wire 4 extending from the simulated blood vessel 3 is connected to the lateral adjustment component 5, and the longitudinal adjustment component 6 is connected to the bottom of the guide wire 4 near the free end.

[0038] In use, the bending angle of the guidewire 4 in the horizontal plane can be changed by the lateral adjustment component 5, while the longitudinal adjustment component 6 controls the degree of bending of the guidewire 4 in the vertical plane. Through the synergistic effect of the lateral adjustment component 5 and the longitudinal adjustment component 6, the bending state of the guidewire 4 can be adjusted, which can simulate different blood vessel paths and improve the realism and challenge of the training.

[0039] In this embodiment, the lateral adjustment component 5 includes a lead screw 53, a slider 54, an adjustment groove 51, and a knob 52. The adjustment groove 51 is formed on the base 1, and the lead screw 53 is installed in the adjustment groove 51. One end of the lead screw 53 extends out of the base 1 and is fixedly connected to the knob 52. The slider 54 is threaded to the lead screw 53 and is slidably installed in the adjustment groove 51. One top end of the slider 54 is connected to the bottom of the guide wire 4 through a connecting rod. The longitudinal adjustment component 6 has the same structure as the lateral adjustment component 5 and is arranged perpendicular to each other.

[0040] In use, manually rotate knob 52 to drive lead screw 53 to rotate, control the movement of slider 54 on lead screw 53, and adjust guide wire 4 from the connecting rod.

[0041] In this embodiment, the simulated blood vessel 3 is provided with multiple sets of thrombosis simulation mechanisms 7. The thrombosis simulation mechanism 7 includes an annular airbag 71 and an air pump 73. The annular airbag 71 is installed in the simulated blood vessel 3, and the annular airbag 71 is connected to the air pump 73 through a pipeline. A control valve 72 is installed on the pipeline.

[0042] In use, the air pump 73 delivers gas into the annular airbag 71, causing the annular airbag 71 to expand and reduce the size of the passage path within the simulated blood vessel 3, thus mimicking the effect of a thrombus. With the cooperation of multiple thrombus simulation mechanisms 7, it is possible to simulate blood vessels of different lengths with thrombi, thereby improving the realism of the training.

[0043] In this embodiment, the bottom of the catheter 8 installed on the guidewire 4 is provided with a notch so that the catheter 8 can advance along the guidewire 4.

[0044] The working principle of this utility model is as follows:

[0045] The lateral adjustment component 5 can change the bending angle of the guidewire 4 in the horizontal plane, while the longitudinal adjustment component 6 controls the degree of bending of the guidewire 4 in the vertical plane. Through the synergistic effect of the lateral adjustment component 5 and the longitudinal adjustment component 6, the bending state of the guidewire 4 can be adjusted, which can simulate different vascular paths and improve the realism and challenge of the training.
