Description

Technical Field

[0001] The invention relates to the technical field of medical treatment accessories, and in particular to an interventional anti-falling device for pneumatic venous thrombosis. Background Art

[0002] The interventional treatment of pneumatic venous thrombosis usually involves stripping the thrombus from the blood vessel to achieve the effect of thrombus treatment; however, due to the different types of blood vessels and the different degrees of thrombosis in patients, some thrombi do not meet the requirements of stripping, but their existence will affect the health or psychology of the patient;

[0003] Therefore, in order to solve this problem, we propose an interventional thrombus prevention device that can effectively prevent thrombus detachment. Summary of the invention

[0004] In view of the defects in the prior art, the present invention provides an interventional anti-dropping device for pneumatic venous thrombosis to prevent the thrombus from falling off.

[0005] In a first aspect, the present invention provides an interventional anti-falling device for pneumatic venous thrombosis, comprising: a supporting portion, the supporting portion being provided with no less than two supporting tubes, and the supporting tubes being arranged opposite to each other; a connecting portion, the connecting portion being arranged on the supporting portion and located between the two supporting tubes, and the two ends of the connecting portion being respectively connected to the supporting tubes; and a covering net portion, the covering net portion being arranged at the supporting portion and located between the two supporting tubes, and being arranged above the connecting portion; wherein the covering net portion comprises an anti-falling net, and the anti-falling net is arranged near the thrombus to prevent the thrombus from falling off.

[0006] Furthermore, the support tube is also provided with weight-reducing holes, and the weight-reducing holes are provided in multiple locations and are evenly distributed on the support tube. In actual use, the purpose of this design is, on the one hand, to reduce the overall weight, and on the other hand, when the opening of the weight-reducing hole contacts the surface of the thrombus or the blood vessel wall, the thrombus or the blood vessel wall is sunken in the weight-reducing hole, so that the limiting and positioning can be achieved, and the so-called slipping of the support tube can be avoided.

[0007] Furthermore, the connecting part includes a connecting sleeve rod, and the connecting sleeve rod includes a connecting rod and a connecting sleeve, wherein two connecting rods are provided and are respectively located on two support tubes, wherein one end of any connecting rod is connected to the support tube, and one end of the connecting rod is located in the connecting sleeve. In actual design, the purpose of this design is to achieve effective connection of the support tubes on both sides, and also to facilitate the stretching and fixing of the anti-drop net to support the thrombus.

[0008] Furthermore, the connection part also includes a connecting drive cylinder, one end of which is connected to one of the support tubes, and the other end of which is connected to another support tube. In actual use, the connecting drive cylinder is a micro cylinder, and its design purpose is to achieve the movement of the driving support tube. Of course, this design is used in conjunction with the above-mentioned connecting sleeve rod, in which the connecting drive cylinder is a double-axis cylinder, and the overall length of the connecting drive cylinder is greater than the connecting sleeve rod, and the connecting drive cylinder is set in the middle position of the support tube, so that the expansion state can be achieved, so that the anti-drop net can be stretched so that it is in full contact with the thrombus and achieves firmness after covering the thrombus. And in the test process, in order to further solve the problem of thrombus detachment, when the anti-detachment net in the device is abutted and fixed with the thrombus, the connecting drive cylinder is driven to achieve its extension. The purpose is to ensure continuous pressurization of the thrombus, and use the anti-detachment net to peel off the thrombus surface. Through interval pressurization, the thrombus can be gradually layered and peeled off, which greatly reduces the blood vessel pressure. At the same time, the peeled surface thrombus can be gradually discharged through the blood due to its small size. In this way, not only anti-detachment is achieved, but also the gradual layered detachment of the thrombus can be achieved, which further ensures the safety of the patient.

[0009] Furthermore, it also includes an outer support sleeve and a balance piece, wherein the outer support sleeve is provided at two locations and is respectively provided at the outer direction of the support tube; the balance piece is provided at multiple locations and is evenly distributed along the sleeve opening of the outer support sleeve. In actual use, the purpose of this design is to achieve a smooth contact with the blood vessel wall and reduce sharp clamping that affects the safety of the blood vessel.

[0010] Furthermore, one end of the balancing member is connected to the support tube, and the other end of the balancing member is connected to the outer support sleeve. In actual use, the purpose of this design is to achieve the expansion and contraction of the balancing member, thereby ensuring a smooth abutment.

[0011] Furthermore, the balancing member includes a connecting tube and a connecting slide rod, one end of the connecting slide rod is slidably installed in the connecting tube; the other end of the connecting slide rod is installed on the outer support sleeve, and the other end of the connecting tube is installed in the support tube. In actual use, this design can achieve the effect of connecting sliding and can effectively ensure the telescopic length. The outer tube wall of the support tube and the outer wall of the outer support sleeve are smoothly abutted against the blood vessel wall.

[0012] Furthermore, it also includes an inner sliding flexible sleeve, which is arranged between the two outer supporting sleeves. In actual use, the purpose of this design is to facilitate blood flow, and the material used is surgical silk thread, microspheres and absorbent gelatin, so that the blood in the blood vessels can flow effectively.

[0013] It can be seen from the above technical solution that the beneficial effects of the interventional anti-falling device for pneumatic venous thrombosis provided by the present invention are:

[0014] (1) In actual application, the purpose of this design is to wrap the thrombus through a net bag, thereby fixing the thrombus, which can effectively prevent the thrombus from falling off and greatly solve the patient's health problems.

[0015] (2) Furthermore, the connecting portion used can effectively realize the connection of the supporting tubes; thus, when the connecting portion is extended or retracted, it can ensure that the two supporting tubes can be effectively connected;

In actual use, the purpose of this design is to wrap the thrombus by a net bag, thereby fixing the thrombus, which can effectively prevent the thrombus from falling off and greatly solve the patient's health problems. Furthermore, the connecting portion 2 used can effectively connect the support tube 11; thus, when the connecting portion 2 is extended or retracted, the two support tubes 11 can be effectively connected; furthermore, the anti-drop net 31 used can effectively hold the thrombus, thus preventing the thrombus from falling off.

[0028] In this embodiment, in order to reduce the weight of the device and reduce the pressure on the blood vessel, the support tube 11 is further provided with a weight-reducing hole 110, and the weight-reducing hole 110 is provided at multiple locations and evenly distributed on the support tube 11.
