Embodiment 1

[0054] The medical catheter system provided by the first embodiment includes:

[0055] The tube body 1 has a long cavity 101 and a short cavity 102 isolated from each other, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the long cavity 101 and the short cavity 102 are two parallel and isolated cavities. The axial position of the distal end of the long lumen 101 is different from the axial position of the distal end of the short lumen 102 , and the axial position of the proximal end of the long lumen 101 is the same as the axial position of the distal end of the short lumen 102 .

[0056] like Figure 5 As shown, the distal end of the long cavity 101 has a first frustum 103, and the distal end of the short cavity 102 has a second frustum 104. The first frustum 103 and the second frustum 104 prevent the medical The catheter system scratches the vessel during introduction.

[0057] like Image 6 As shown, the junction between the distal end of the short lum...

Embodiment 2

[0071] Both the second embodiment and the first embodiment have a pipe body 1 , a stress diffusion pipe 2 and a connection seat 3 . The structure of the stress diffusion pipe 2 in the second embodiment is the same as that of the first embodiment. The connection method is different from the first embodiment. In the second embodiment, the pipe body 1 and the connection seat 3 are connected by bonding, and the structures of the pipe body 1 and the connection seat 3 are different. The differences are as follows:

[0072] like Figure 8 and Figure 9 As shown, in the medical catheter system provided in the second embodiment, the tube body 1 also has a long lumen 101 and a short lumen 102 that are parallel and isolated from each other, wherein the axial position of the proximal end of the long lumen 101 is the same as the proximal end of the short lumen 102 The axial positions are different, and the distal axial position of the long lumen 101 is the same as the distal axial positio...

Abstract

The invention relates to a medical catheter system. The medical catheter system comprises a catheter body and a connecting seat, wherein the catheter body is provided with a long cavity and a short cavity which are isolated from each other; connecting seat is provided with an inner hole and one or more guide hole groups, the catheter body is connected with the connecting seat through the inner hole, and the guide hole groups communicate with the long cavity and / or the short cavity after the catheter body is connected with the connecting seat; and therefore, the medical catheter system is provided with at least two guide wire channels which are independent of each other. The medical catheter system provided by the invention can cooperate with a guide wire to establish the two guide wire channels which are not interfered with each other in the aorta, so that necessary approach conditions are provided for a main thoracic stent and a branch thoracic stent, the stent introduction operation is simplified, an operator can use the guide wire channels which are not interfered with each other according to the specific requirements of an interventional instrument, the problem of mutual winding of the guide wires is solved, the operation step of unwinding by an operator is reduced, and the time cost is saved for an operation.

Description

technical field [0001] The present invention relates to the field of vascular intervention, in particular to a medical catheter system. Background technique [0002] As a minimally invasive treatment, vascular interventional therapy improves the survival probability for patients with vascular disease who cannot tolerate surgery. In some patients with arterial dissection, the left clavicle artery is often involved in the lesion site, and endovascular repair with thoracic main branch stents has better clinical efficacy than fenestrated stents and chimney stents. The main stent is used to reconstruct the thoracic aorta, and the branch stent is used to reconstruct the left subclavian artery. [0003] In vascular interventional procedures, the guide wire needs to be used in conjunction with the catheter. After the first channel is established, the catheter is withdrawn, leaving the guide wire in the lumen; when the operator establishes the second guide wire channel, it is diffi...
