Detailed Description
In order to facilitate understanding of the technical scheme 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. 1-11, a covered catheter for vascular puncture blocking comprises a catheter body 1, wherein a blocking film 2 is arranged on the surface of one end, extending into a blood vessel, of the catheter body 1, a traction wire 3 is connected to the blocking film 2, the blocking film 2 is provided with a first state attached to the surface of the catheter body 1 and a second state arranged in a folding manner, the traction wire 3 is pulled, so that the blocking film 2 is deformed, at least part of the blocking film 2 is separated from the connection with the catheter body 1, and a folding structure is formed 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 outer sheath of the original puncture sheath, the plugging film 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 outer sheath are pulled away, the plugging film 2 is effectively plugged at the puncture opening to achieve the hemostatic effect, the plugging film 2 can be organically fused with human tissues, and finally, local effective revascularization is realized, so that the local vascular protection is facilitated, and the possibility of secondary operation is provided.
The catheter body 1 is made of elastic materials, and can be a composite pipe of one of polyimide, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer, polyethylene, polyether ether ketone, nylon, polyether block polyamide and nylon and stainless steel wires or a composite pipe of the high-molecular materials which are not less than two.
The blocking film 2 is in the prior art, and can be particularly a common biological film in clinical operation, such as biological grafts harvested by porcine Small Intestine Submucosa (SIS), new materials of inflammation-regulating high molecular polymers and the like, and can be absorbed by human bodies.
The catheter body 1 is provided with a first through passage 11 for accommodating a guide wire, and when in use, 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 overflowing from the end of the operation portion 12.
The operation part 12 is provided with a liquid flow pipe 4, the end part of the liquid flow pipe 4 is provided with 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, the tee joint 41 is opened, then blood is drawn, and once the blood flows out of the tee joint 41, one end of the catheter body 1 is positioned in the blood vessel. Meanwhile, a drug such as heparin or physiological saline may be injected into the blood vessel through the tee 41.
As shown in FIG. 7, the diameter of the catheter body 1 is 0.3mm-30mm, and the size of the rectangular opening of the plugging membrane 2 is 0.5mm multiplied by 2mm to 60mm multiplied by 200mm.
The plugging film 2 is a rectangular structure, and is attached to the surface of the catheter body 1 to form a ring-shaped structure (in the structure, a slit is formed at the joint of two ends of the plugging film 2) surrounding the catheter body or a fan-shaped ring-shaped structure partially surrounding the catheter body. Pulling the two structures through the pulling wire 3 can make the plugging film 2 fall off from the catheter body 1 and form a folded solid patch.
Preferably, the blocking film 2 has a circular ring structure, and when stacked into a solid dough sheet, the size thereof is 0.5mm×0.5mm to 60mm×60mm.
Preferably, the diameter of the catheter body 1 is 2mm-10mm, and the dimension of the rectangular opening shape of the plugging membrane 2 is 5mm multiplied by 20mm to 20mm multiplied by 100mm; when the plugging film 2 is in a circular ring structure, the dimension of the plugging film is 5mm multiplied by 20mm when the plugging film is stacked into a solid dough sheet.
The plugging film 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 at the same time, so that the injury to the human body is avoided. The plugging film 2 can be separated from the catheter body 1 and form a folded structure by pulling the pulling wire 3 outwards.
The biological adhesive can be used as a common clinical biological adhesive, and is dissolved in blood, so that complications such as desquamation, thrombus and the like are not caused, and the biological adhesive loses viscosity when meeting blood. Such materials are commonly available in clinic at present. When the fixing device is outside a human body, the fixing effect is good. After entering the blood vessel, the adhesive is softened and loosened by contacting with blood, and can be removed by slight force. In blood, the biological adhesive loses viscosity rapidly due to the influence of blood, and the whole body of the biological adhesive can be smoothly separated from the catheter by slightly pulling the wire 3, and the subsequent operation is carried out.
Specifically, as shown in fig. 7-8, the plugging film 2 is provided with traction wires 3 in a positive and negative penetrating manner. Preferably, the traction wire 3 and the blocking film 2 are arranged in a sewing way, a bottleneck does not exist clinically, the common intermittent sewing is adopted, the wire body is stuck on the surface of the blocking film 2 through a biological adhesive, and the wire body is loosened after entering a blood vessel. The two ends of the thread at the inner end of the blood vessel can be integrated, namely, the inner and outer parts are connected, so that the stability of the thread is better.
Two traction wires 3 are arranged on each plugging film 2, and 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 separated from the catheter body 1 better and a folding structure is formed. In this example, a biofilm of 40mm length by 10mm width by 0.3mm thickness is taken as an example, and the distance between the two traction wires 3 is 0.6mm, and after folding, a folded structure of 10mm length by 10mm width by 1.5mm thickness is formed.
If the length of the biological film is increased, the number of layers after folding is increased, and finally the thickness of the folded plugging film 2 is correspondingly increased;
2. The interval between the traction wires 3 is preferably larger than half of the width of the film, and the traction wires are not easy to wrinkle and break when being pulled and folded;
3. The actual folding effect can be reduced due to the crease damage, the puncture opening is similar to a circle, and the blood pressure is larger, so that when the type 1 catheter body is selected, the selection is needed according to the diameter of the puncture opening or the diameter of the outer sheath, and the length of the plane side after the folding of the biological membrane is larger than 1.5 times of the diameter of the puncture opening.
In practical use, the two ends of the membrane are elliptical or the single traction wire 3 is arranged in the middle of the wide part of the membrane and is intermittently sewn on the surface of the membrane, but the elliptical edge is difficult to adhere to a catheter, and the single traction wire 3 is easy to cause the problems of uneven folding force, collapse in appearance, difficult fixation of the single wire and the like of the plugging membrane 2.
Preferably, a section of the traction wire 3 near the plugging film 2 is also adhered to the catheter body 1 through biological glue. According to the actual process, the traction wire 3 is the best choice clinically, wherein the thin catgut wire which can be absorbed by human body or the thin sliding wire which cannot be absorbed by human body is selected. Both of them are weak in rejection. After the absorbable traction wire 3 is used for fixation outside the skin, the absorbable traction wire can be automatically absorbed without disconnecting the wire; the sliding wire is convenient for clinical operation and is easy to detach.
In addition, through local fine tuning, 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 perivalvular leakage, bronchial leakage and esophageal leakage, and the dilemma of clinical situations can be solved to a certain extent.
As shown in fig. 9, the three-dimensional patch formed by folding the plugging film 2 is plugged on the puncture, and the plugging film 2 is only required to be fixed by completely removing the catheter body 1 and through the traction wire 3.
As another embodiment of the present invention, as shown in fig. 10, the two traction wires 3 on the plugging film 2 may be inserted in the opposite direction, but the two traction wires 3 are twisted into one drawing section, so that the operation is convenient.
As another embodiment of the present invention, as shown in fig. 11, the traction wire 3 on the sealing membrane 2 may be disposed in a spiral shape and inserted in a positive and negative direction, so that the sealing membrane 2 after being stacked is more firm before being stacked, and is prevented from being separated from the stacked second state due to the flow of blood.
A vascular puncture plugging device comprises an outer sheath, wherein a covered catheter for vascular puncture plugging is movably arranged in the outer sheath. The sheath is the sheath of the puncture sheath in the prior art, after the puncture sheath is used, the guide wire and the sheath are left in the blood vessel, when the puncture sheath is used, the catheter body 1 is placed in the blood vessel along the sheath of the puncture sheath, the plugging film 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 out, the plugging film 2 is effectively plugged at the puncture opening to achieve the hemostatic effect, the plugging film 2 can be organically fused with human tissues, and finally, local effective revascularization is realized, so that the local vascular protection is facilitated, and the possibility of secondary operation is provided.
