Embodiment 1

[0039] Embodiment 1 is basically as attached figure 1 and figure 2 Shown: a thrombus interceptor, including a support bag 1 and a communication tube 2 fixedly connected to the right side of the support bag 1, the support bag 1 is integrally formed with a placement hole 3 and a plurality of flow holes 4, and the cross-section of the support bag 1 The outer contour is circular, the placement hole 3 is located in the center of the support bag 1, and the circulation hole 4 is in the circumferential direction of the placement hole 3; the diameter of the circulation hole 4 is smaller than the minimum cross-section of the thrombus, the circulation hole 4 is used for blood to flow through, and the placement hole 3 is used for To accommodate the catheter 100 or the guide wire, the support bag 1 can abut against the inner wall of the blood vessel after being inflated; the connecting pipe is communicated with the support bag 1, and the connecting pipe can be connected to an external mac...

Embodiment 2

[0047] The second embodiment is basically as attached Figure 3 to Figure 5 As shown, the second embodiment makes the following improvements on the basis of the first embodiment: the support bag 1 is formed with a connecting rib 8, the connecting rib 8 is in a spiral shape, and the connecting rib 8 gradually extends from the center of the support bag 1 to the outer wall of the support bag 1 ; combine image 3 and Figure 4 , when the number of connecting ribs 8 is multiple, this embodiment takes five as an example, and the multiple connecting ribs 8 are evenly distributed along the circumferential direction of the center of the support bag 1 . combine Figure 5 , when the number of connecting ribs 8 is one, the spiral connecting ribs 8 extend from the center of the support bag 1 to the outer wall of the support bag 1 in a spiral manner; crease.

[0048] The specific implementation process is as follows: when the present embodiment is adopted, the setting of the helical con...

Embodiment 3

[0050] The third embodiment is basically as attached Image 6 As shown, the third embodiment makes the following improvements on the basis of the second embodiment: the end face of the support bag 1 away from the connecting pipe is a convex curved surface or a conical surface. Image 6 Take the convex surface as an example.

[0051] When using this embodiment, the support bag 1 is away from one end of the connecting pipe (that is, the attached Image 6 The left end of the support bag 1) extends into the blood vessel first, and the end face is an outer curved surface or a tapered surface, which is conducive to reducing the friction during the insertion of the support bag 1 into the blood vessel (or insertion into the target tube); in addition, the outer curved surface or the tapered surface of the support bag 1 The intercepted thrombus acts as a diversion, and the intercepted thrombus will move to the edge of the support bag 1 close to the blood vessel wall, reducing the speed...

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a thrombus interceptor which comprises a supporting bag and a communicating pipe, the supporting bag is provided with a placement hole and a plurality of circulation holes, the diameter of the circulation holes is smaller than the minimum section of thrombus, the circulation holes are used for blood to flow through, the placement hole is used for containing a catheter, and the supporting bag can abut against the inner wall of a blood vessel after bulging; the connecting pipe is communicated with the supporting bag, the connecting pipe can be externally connected with a machine so that the supporting bag can be swelled or shrunken, and the supporting bag can be filled with a contrast agent. According to the scheme, the thrombolysis catheter is matched with the interceptor for use, so that integration of a thrombolysis function, a thrombus extraction function and a thrombus interception function can be realized by virtue of an ultrasonic technology; the problem that thrombus is intercepted through a metal filter screen in the prior art is solved, and a thrombus patient can be treated and cured in time even in the field and other sites with poor medical conditions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombus interceptor. Background technique [0002] In existing medicine, there are many cases of thrombosis in blood vessels, including arterial thrombosis and venous thrombosis. For common limb arteriovenous thrombosis, surgery for thrombectomy is more traumatic to patients and there are many postoperative complications. Therefore, in clinical practice, the method of radiological intervention is generally used. For veins, the method of thrombectomy can be used, or the method of thrombolysis can be used. Whether it is thrombectomy or thrombolysis, the catheter needs to be inserted into the blood vessel, and then the catheter can be used. Aspirate the thrombus or use a catheter to inject drugs to dissolve the thrombus. However, whether it is thrombolysis or thrombectomy, in the process, there is a probability that the thrombus will fall off the blood vessel wall and mov...
