In order to facilitate understanding of the technical solutions of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in fig. 1 to 11, a covered catheter for blood vessel puncture occlusion includes a catheter body 1, wherein an occlusion film 2 is disposed on a surface of one end of the catheter body 1 extending into a blood vessel, a pull wire 3 is connected to the occlusion film 2, the occlusion film 2 has a first state adhered to the surface of the catheter body 1 and a second state arranged in a folded manner, the pull wire 3 is pulled to deform the occlusion film 2, and at least a part of the occlusion film 2 is separated from the catheter body 1 and forms a folded structure to realize the transition from the first state to the second state. The catheter body 1 can be placed into a blood vessel along the sheath of the original puncture sheath, the plugging membrane 2 is separated from the catheter body 1 through the traction wire 3 to form a folding structure, the guide wire, the catheter body 1 and the sheath are pulled away, so that the plugging membrane 2 is effectively plugged at the puncture hole to achieve the hemostatic effect, the plugging membrane 2 can be organically fused with human tissues, and finally local effective revascularization is realized, thereby being beneficial to protecting local blood vessels and providing the possibility of re-operation.
The catheter body 1 is made of an elastic material, and specifically can be a composite tube made of one of polyimide, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer, polyethylene, polyether ether ketone, nylon, polyether block polyamide and nylon and a stainless steel wire or a composite tube made of more than two of the above high-molecular materials.
The plugging membrane 2 is the prior art, can be a biological membrane commonly used in clinical operation, such as a biological graft harvested from porcine Small Intestine Submucosa (SIS), a new material of an inflammation regulating high molecular polymer and the like, and can be absorbed by a human body.
The catheter body 1 is internally provided with a through first channel 11 for accommodating a guide wire, and when the catheter is used, the catheter body 1 extends into a blood vessel along the guide wire to prevent the catheter body 1 from puncturing the blood vessel.
An operation part 12 is arranged at one end of the catheter body 1 positioned outside the blood vessel, and a one-way valve 13 is arranged at the end part of the operation part 12. The check valve 13 prevents blood from escaping from the end of the operation portion 12.
The operating part 12 is provided with a liquid flow pipe 4, the end part of the liquid flow pipe 4 is a tee joint 41, the tee joint 41 is in a closed state at ordinary times, the catheter body 1 is stretched into a blood vessel, then the tee joint 41 is opened, blood is drawn, and once blood flows out of the tee joint 41, one end of the catheter body 1 is positioned in the blood vessel. At the same time, agents such as heparin, physiological saline, etc. may be injected into the blood vessel through the three-way tube 41.
As shown in figure 7, the diameter of the catheter body 1 is 0.3mm-30mm, and the opening size of the plugging membrane 2 is 0.5mm multiplied by 2 mm-60mm multiplied by 200 mm.
The occlusion membrane 2 is a rectangular structure, and is attached to the surface of the catheter body 1 to form a circular structure (in the structure, a slit is formed at the joint of two ends of the occlusion membrane 2) surrounding the catheter body or a fan-ring structure partially surrounding the catheter body. The two structures are pulled by the traction wire 3, so that the plugging film 2 can fall off from the catheter body 1 and can be folded into a three-dimensional patch.
Preferably, when the plugging film 2 has a circular structure, the size of the plugging film is 0.5mm × 0.5mm to 60mm × 60mm when the plugging film is stacked into a three-dimensional patch.

The plugging membrane 2 is arranged on the catheter body 1 through biological glue, and the biological glue has certain viscosity and can be slowly dissolved in a human body without causing harm to the human body. The plugging membrane 2 can be separated from the catheter body 1 and forms a folding structure by pulling the traction wire 3 outwards.
The biological adhesive can be used as a clinical common biological adhesive, is dissolved in blood, does not cause complications such as desquamation, thrombus and the like, and loses viscosity when meeting blood. The material is commonly used and easily obtained at present in clinic. When the utility model is outside the human body, the fixing effect is good. After entering the blood vessel, the adhesive is contacted with the blood to soften and loosen the adhesive and can fall off by slight force. In blood, the biological adhesive loses viscosity rapidly due to the influence of blood, and the whole body can be smoothly separated from the catheter by slightly pulling the silk thread 3, and subsequent operation is performed.
Specifically, as shown in fig. 7 to 8, the plugging film 2 is provided with pull wires 3 which are inserted in the front and back directions. Preferably, the traction wire 3 and the occlusion film 2 are arranged by suturing, so that no bottleneck exists clinically, the suture is a common intermittent suture, and the wire body is attached to the surface of the occlusion film 2 through biological adhesive and is loosened after entering a blood vessel. The two thread ends at the inner end of the blood vessel can be integrated, namely, the inner part and the outer part are connected, so that the stability of the thread is better.
Two traction wires 3 are arranged on each plugging film 2, when the traction wires 3 are pulled outwards, the two traction wires 3 need to be pulled simultaneously, so that the plugging films 2 can be better separated from the catheter body 1 and form a folding structure. In this embodiment, a biofilm with a length of 40mm, a width of 10mm and a thickness of 0.3mm is taken as an example, the distance between the two pull wires 3 is 0.6mm, and a folded structure with a length of 10mm, a width of 10mm and a thickness of 1.5mm is formed after the two pull wires are folded.
Wherein, 1, if the length of the biological membrane is increased, the number of layers after folding is increased, and finally the thickness of the folding plugging membrane 2 is correspondingly increased;
2. the distance between the drawing lines 3 is preferably larger than half of the width of the film, and the drawing and folding are not easy to wrinkle and break at the distance;
3. the actual folding effect can shrink due to wrinkling and damage, the puncture is circular-like, and the blood flow pressure is large, so when the model of the catheter body 1 is selected, the selection needs to be carried out according to the diameter of the puncture or the diameter of the sheath, and the length of the side of a plane of a folded biological membrane is more than 1.5 times of the diameter of the puncture.
In practical use, the two ends of the membrane are oval or a single traction line 3 is arranged in the middle of the width of the membrane and is discontinuously sewn on the surface of the membrane, but the oval edge is difficult to adhere to the catheter, and the single traction line 3 is easy to cause the problems of uneven folding force, collapse of appearance, difficult fixation of the single line and the like of the plugging membrane 2.

According to the actual process, the selection of the human body absorbable thin catgut line or non-absorbable thin slippery line as the traction line 3 is the best choice in clinic. Both of them are weak in human body rejection. After the absorbable traction wire 3 is fixed outside the skin, the self-absorption can be carried out without removing the wire; the use of the slide wire is convenient for clinical operation and the wire is simple and convenient to remove.
In addition, through local fine adjustment, the diameter of the catheter body 1 and the size of the plugging film 2 are changed, the application scene of the covered catheter can be widened to the plugging of paravalvular leakage, bronchial leakage and esophageal leakage, and the dilemma of the clinical situation can be solved to a certain degree.
As shown in fig. 9, the three-dimensional patch formed by folding the blocking film 2 is blocked on the puncture, and only the catheter body 1 needs to be completely removed and the blocking film 2 needs to be fixed by the pull wire 3.
As another embodiment of the present invention, as shown in fig. 10, the two pulling wires 3 on the plugging film 2 may be arranged in a positive and negative penetrating manner, but the two pulling wires 3 are twisted into one leading segment for convenient operation.
In another embodiment of the present invention, as shown in fig. 11, the pull wires 3 on the occlusion film 2 may be spirally and reversely inserted, so that the stacked occlusion film 2 is more firmly held before it is stacked, and the blood is prevented from being separated from the stacked second state by the flow of the blood.
