Problems solved by technology

First of all, it is difficult to determine whether all varicose veins, especially the perforating veins, have been effectively treated; secondly, it is difficult to determine whether the trunk of the great saphenous vein has been effectively closed after endovascular closure; finally, conventional treatment procedures are likely to lead to misdiagnosis of special patients, such as Double great saphenous vein, Cockett syndrome, deep vein post-thrombotic syndrome, K-T syndrome (K-T Syndrome), etc.

Embodiment 1

[0045] Such as Figure 1 to Figure 5 The visualized endoluminal closure system for varicose veins of the lower extremities shown, including digital subtraction angiography machine 1, vascular puncture short sheath 2, guide wire 3, double-lumen catheter 4, laser therapy instrument 5, visualized laser optical fiber 6 and operating table 7 . Both the guide wire 3 and the visualization laser fiber 6 are compatible with the double-lumen catheter 4 . The digital subtraction angiography machine 1 is used for imaging observation of the lesion, the vascular puncture short sheath 2 is used for puncturing blood vessels, the guide wire 3 is used in conjunction with the double-lumen catheter 4, and the lesion is super-selected to penetrate the vein, and the visual laser fiber 6 is used along the double-lumen catheter. The lumen catheter 4 reaches the lesion and performs visual treatment on the lesion under the action of the laser therapeutic apparatus 5 .

[0046] Specifically, the digit...

Embodiment 2

[0052] Such as Figure 1 to Figure 9 As shown, the structure of this embodiment is similar to that of Embodiment 1, the difference is that a separation auxiliary device 8 sleeved on the visualization laser fiber 6 is added, and the auxiliary visualization laser fiber 6 is more easily separated from the fiber cavity 43 through the opening 431 . Although the fiber tail is provided with a reinforcing part 63, there is still a risk of breakage during the tearing process. By setting the separation auxiliary device, while assisting the separation, the visualization laser fiber 6 is further protected to avoid the visualization laser fiber 6 breakage.

[0053] Specifically, the outer diameter of the front end of the separation auxiliary device 8 is smaller than the inner diameter of the fiber cavity 43 to ensure that the front end can be inserted into the fiber cavity 43 , thereby protecting the visualization laser fiber 6 and guiding its separation from the fiber cavity 43 . The sep...

Embodiment 3

[0058] Such as Figure 1 to Figure 10 As shown, the structure of this embodiment is similar to that of Embodiment 2, except that a superselection conduit 9 is added. For some patients with tortuous veins that are difficult to penetrate and some patients with perforating branch reflux, it is difficult to use the double-lumen catheter 4 for superselection, and it is easier to use the guide wire 3 and the superselection catheter 9 for superselection, which can speed up the operation process.

[0059] Specifically, compared with the common single-bend pipe in the prior art, the super-selection catheter 9 of this embodiment adopts a single-bend catheter with a three-layer structure, and the three-layer structure from the inside to the outside is made of PTFE material, metal braid and Pebax material respectively. The texture is softer and more slender, suitable for walking in tortuous veins. The inner diameter of the superselective catheter 9 is larger than the outer diameter of the...

Abstract

The invention discloses a visualized intracavitary closure system for varicose veins of lower extremities, which comprises a digital subtraction angiography machine, a short sheath for blood vessel puncture, a guide wire, a double-lumen catheter, a laser therapeutic instrument, a visualized laser optical fiber and an operating table; The shadow angiography machine is erected on one side of the operating table; the visualized laser optical fiber is connected to the laser therapy instrument; the double-lumen catheter includes a catheter body and a guide wire lumen and an optical fiber lumen arranged in parallel to the axial direction in the catheter body. The guide wire and the visualized laser optical fiber are respectively adapted to the guide wire lumen and the fiber optic lumen. The present invention integrates preoperative imaging evaluation, intraoperative visualization operation, and postoperative imaging review, simplifies surgical operations, avoids repeated operations, increases the burden on patients, and reduces postoperative recurrence.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a visualization intracavity closure system for varicose veins of lower extremities. Background technique [0002] Varicose veins of lower extremities is a common venous disease in vascular surgery, and the incidence rate in the population can be as high as 20%. The incidence of varicose veins of lower extremities increases with age, which seriously affects people's quality of life and increases the economic burden of society. Patients with varicose veins of lower extremities often present with lumbrical protrusions, soreness, heaviness, fatigue and other discomforts. If not treated in time, they may develop limb edema, skin eczema, pigmentation, venous ulcers and even thrombophlebitis. , Life has brought a great impact. [0003] At present, the diagnosis and preoperative examination of lower extremity varicose veins mainly rely on vascular color Doppler ultrasound and d...
