Problems solved by technology

[0004] In the early 1990s, the main treatment for iatrogenic femoral pseudoaneurysm was surgery, which had a high efficiency rate, but the surgical trauma was large, the cost was high, patients could not tolerate it, and there were many complications, so it was difficult to popularize it.
Subsequent non-invasive treatment methods, simple compression and ultrasound-guided compression (UGC) therapy appeared and were applied clinically. Studies have shown that the effective rate of UGC treatment is higher than that of simple compression therapy, but it is still unsatisfactory, mostly at 60% to 70%. Obesity, dual antiplatelet or anticoagulant drug therapy, or larger tumor with shorter neck

Embodiment 1

[0036] The non-invasive closure device for femoral artery pseudoaneurysm has the advantages of non-invasive, convenient, reusable, low cost, and can reduce serious complications, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, it is specially set to the following structure:

[0037] The non-invasive closure device for femoral artery pseudoaneurysm includes a mounting plate 1 and a compression head 2 .

[0038] The mounting plate 1 is used for mounting the compression head 2 and for combining with the strap for tightening on the patient's body. The mounting plate 1 is provided with a connecting portion, which is used for connecting with a strap, and the mounting plate 1 is tightened on the patient's body through the strap connected thereto, so that the compression head 2 can be accurately pressed against the patient's skin surface.

[0039] The compression head 2 is used for directly contacting the patient's skin to compress the mouth or neck of the femoral arte...

Embodiment 2

[0044] The present embodiment is further optimized on the basis of the above-mentioned embodiment, and further, in order to better realize the present invention, the following setting structure is specially adopted:

[0045] In this embodiment, the relative distance between the compression head 2 and the mounting plate 1 of the noninvasive femoral artery pseudoaneurysm closure device is adjusted by means of a screw 5 .

[0046] Specifically, the compression head 2 is adjustable and connected to the mounting plate 1 through an adjustment bracket.

[0047] The adjusting bracket includes a guide rod 4, a screw rod 5 and a push plate 6, and the guide rod 4 and the screw rod 5 are arranged vertically. The push plate 6 and the pressing head 2 are respectively located at two ends of the mounting plate 1 in the vertical direction. The mounting plate 1 extends laterally, and two vertical through holes are opened on the mounting plate 1 .

[0048] Wherein, the through hole used to pen...

Embodiment 3

[0055] The present embodiment is further optimized on the basis of the above-mentioned embodiment, and further, in order to better realize the present invention, the following setting structure is specially adopted:

[0056] In this embodiment, the number of guide rods 4 of the non-invasive closure device for femoral artery pseudoaneurysm is set to two, the mounting plate 1 is provided with three vertical through holes, and the three through holes are arranged in sequence along the horizontal direction. One through hole in the middle is used for penetrating the screw rod 5 , and the other two through holes are light holes for penetrating the guide rod 4 . The two guide rods 4 are arranged in sequence along the transverse direction and are respectively located on both sides of the screw rod 5 .

[0057] The compression head 2 has a certain lateral length, and two ends in the lateral direction are respectively connected with corresponding guide rods 4 .

[0058] In this embodim...

Abstract

The invention provides a non-invasive closer for femoral artery pseudoaneurysm, relates to the technical field of medical instruments, solves the problems of large operative wound, high cost and many complications caused by surgical treatment in the prior art, and comprises a mounting plate and a compression head, the compression head is adjustably mounted on the mounting plate, and the compression head can be adjusted along a vertical path in a manner of being far away from or close to the mounting plate and being positioned at a certain point in the vertical direction; the mounting plate is provided with a connecting part, the connecting part is used for being connected with a bandage, and the mounting plate is tightened on the body of a patient through the bandage connected with the mounting plate so that the pressing head can abut against the surface of the skin of the patient. Compared with the prior art, the device has the advantages of being noninvasive, convenient, reusable, low in cost, capable of reducing serious complications and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a non-invasive closure device for femoral artery pseudoaneurysm. Background technique [0002] With the popularization of interventional technology and the advancement of interventional materials, the number of endovascular treatments for cardiovascular and cerebrovascular and peripheral blood vessels is increasing year by year, but the incidence of iatrogenic pseudoaneurysm caused by puncture is gradually increasing, especially the femoral artery pseudoaneurysm. The occurrence of aneurysm, it has been reported that the incidence is about 0.3% to 8.0%. [0003] Iatrogenic femoral artery pseudoaneurysm is essentially a rupture of the femoral artery wall caused by iatrogenic operation through the femoral artery. The pulsatile cystic hematoma formed by tissue encapsulation has no three-layer structure in the arterial vessel wall, medial and adventitia, and is not a true dil...
