Embodiment 1
[0030] see Figure 1 to Figure 7 , the present invention provides a technical solution:
[0031] A thrombus ablation device, comprising a pressing box 1, a partition 1c, a transmission straight rod 2a, a transmission gear 2b, a rotating rod 3, an outer tube 4, a nozzle 5, a blade 6, a suction plug 7 and a guide wire 8, and the pressing box A partition 1c is built in the body 1, and the partition 1c divides the pressing box 1 into two parts, the first box 1a and the second box 1b, the pressing box 1 is connected with the outer tube 4, and the outer tube 4 is divided into the second box A tube body 4c and a second tube body 4d are two parts, the first box body 1a communicates with the first tube body 4c, the second box body 1b communicates with the second tube body 4d, and a circle is set in the partition 1c and the outer tube 4 shaped channel, the rotating rod 3 runs through the circular passage of the partition 1c and the outer tube 4, one side of the rotating rod 3 stretches...
Embodiment 2
[0034] see Figure 8 , the present invention provides a technical solution, which is generally the same as Embodiment 1, the difference is that:
[0035]The side of the pressing box 1 is a flexible side 1i, the flexible side 1i can change shape with the change of the volume of the pressing box 1 and has no elasticity. The first box wall 1e of the first box 1a and the second box 1b The second box wall 1h stretches out to press the box body 1, the extension part I1e-1 of the first box wall 1e and the extension part II1e-2 of the second box wall 1h fix the transmission straight rod 2a in the middle, and the transmission straight rod 2a meshes with the transmission gear. A motor is provided on the transmission gear 2b, and the motor can be set to alternately rotate clockwise and counterclockwise at a certain frequency. While the rotating rod 3 drives the blade 6 to rotate, the compression and expansion of the first box body 1a and the second box body 1b can realize thrombolytic dr...
Embodiment 3
[0038] see Figure 9 , the present invention provides a technical solution, substantially the same as Embodiment 2, the difference is:
[0039] A limiting device 1j is installed on the partition 1c, a limiting groove 1k is set on the limiting device 1j, and protrusions corresponding to the limiting groove 1k are set on the first box wall 1e and the second box wall 1h, so that the first The box wall 1e and the second box wall 1h can move stably along the limiting device 1j. Compared with the second embodiment, this embodiment presses the movement of the box body 1 more regularly and stably.
[0040] The above three embodiments of the present invention can realize: 1. The three steps of rotating the blade, injecting thrombolytic drugs, and extracting thrombus fragments are combined through the transmission structure, and the blade can be driven to rotate by pressing the pressing box 1 , or when the motor drives the blade 6 to rotate, pressing the box can complete the steps of i...
