Description

A kind of cardiovascular and cerebrovascular microtubular

Technical field

The utility model is related to technical field of medical instruments, more particularly to a kind of cardiovascular and cerebrovascular microtubular.

Background technology

At present, with the raising of cardiovascular morbidity, the interventional therapeutic technique of cardiovascular and cerebrovascular disease is developed rapidly.The technology It is a kind of Minimally Invasive Surgery implemented under angiogram, is the third the treatment side for being different from the disease outside medical and surgical treatment Formula.

Cardiovascular and cerebrovascular microtubular is a kind of crucial equipment of PCI, is an elongated polymer composite pipe, its Main function is as follows：1. set up the passage that the equipment such as micro-wire enter lesion vesselses；Carried 2. being promoted in tortuous blood vessel for seal wire For support force, ability of the seal wire by lesion is lifted；3. it is intravascular that offer passage enables contrast agent smoothly to introduce, radiography effect is produced Really.Existing cardiovascular and cerebrovascular microtubular is poor especially by the ability of inaccessible section by tortuous blood vessel and narrow blood vessel, it is necessary to Guided using seal wire, and this conduit is unfavorable for adjusting the direction of guiding wire.

Utility model content

The technical problems to be solved in the utility model is easy to operate simultaneously there is provided one kind for above-mentioned the deficiencies in the prior art And operating difficulty can be greatly reduced, reduce the cardiovascular and cerebrovascular microtubular of patient's pain.

In order to solve the above technical problems, technical solution adopted in the utility model is：

A kind of cardiovascular and cerebrovascular microtubular, including head, body portion and the afterbody that can be connected with three-way connection, its feature exist In：Head is provided with inclined-plane, and Marking ring is provided with the body portion on head；Microtubular material is medical macromolecular materials；It is micro- to lead Outer tube layer is provided with superslide coating.

Preferably, inclined-plane is is 15 °~25 ° with head tube cavity axis angle, Beveled ends are arc.

Preferably, the tube wall embeded guidewire of microtubular, seal wire end is arranged on the outside of inclined-plane and straight bevel facet is set.

Preferably, Marking ring is gold material.

It is using the beneficial effect produced by above-mentioned technical proposal：The utility model reasonable in design, it is easy to operate, It is easy to, by tortuous, narrow blood vessel, microtubular is greatly improved by the ability of inaccessible section, while reducing microtubular With the friction of vascular wall, the damage to vascular wall is reduced, operating difficulty is reduced, dramatically reduce the slight illness of patient, had There is good clinical therapeutic efficacy.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Embodiment 1：As shown in figure 1, a kind of cardiovascular and cerebrovascular microtubular, including head 1, body portion 2 and can be with three-way connection Connected afterbody 3, head 1 is provided with inclined-plane 11, and Marking ring 12 is provided with the body portion 2 on head 1；The microtubular material is Medical macromolecular materials, the microtubular outer layer is provided with superslide coating.Afterbody 3 is referred to as near-end, head close to operator, the end 1 is used to enter in the blood vessel of patient, and the end is referred to as distal end.Microtubular tip is in ramp structure form, allows microtubular more Plus conveniently, in flexible intravasation.Marking ring 12 is used to position the distal end of microtubular in patient's body in operation technique, It is easy to doctor more accurately to determine therapentic part.The setting of the microtubular outermost layer superslide coating significantly reduces microtubular Frictional resistance between vascular wall, is easy to microtubular to pass through blood vessel, until reaching the distal end of blood vessel.The microtubular energy The passage that the equipment such as micro-wire enter lesion vesselses is enough set up, changes the direction on inclined-plane 11 by rotating microtubular afterbody 3, so that The direction of advance of seal wire 7 is adjusted, and then lifts ability of the microtubular by lesion, the operation difficulty of operation is reduced.Inclined-plane 11 Set, while also strengthening the ability for conveying contrast agent to blood vessel distal end in operation, with faster and better development effect.

As shown in Figures 2 to 5, preferably, inclined-plane 11 is with the tube chamber axis angle of head 1 to be 15 °~25 °, inclined-plane 11 End is arc.The setting on the inclined-plane 11, make that the tip of microtubular becomes is tiny, while it is certain flexible to ensure that it has again Degree, tip is curved, the resistance that microtubular is subject in the blood vessel is reduced to minimum, while the damage to vascular wall is avoided, More freely it can advance in the blood vessel.As shown in figure 3, when microtubular insertion near-end bifurcated vessels section 4, due to the point of inclined-plane 11 End is tiny, preferable by property, it is easier to the lesion blood treated by adjusting the afterbody 3 of microtubular needed for selective insertion Pipe.Inclined-plane 11 greatly reduces the frictional force of microtubular and vascular wall simultaneously, so as to reduce the damage to vascular wall.Such as Fig. 4 institutes Show, when microtubular insert band thrombus or plaque neovascularization section 5, inclined-plane 11 can be more convenient, flexible by narrow positions, greatly Frictional force when big reduction microtubular is contacted with vascular plaque or thrombus, so that the risk of patch and thrombus breaks loose is reduced, and then Reduce the risk of the intraoperative compliactions such as blood vessel embolism.As shown in figure 5, when microtubular inserts tortuous vessel segment 6, the tip of inclined-plane 11 Tiny, pliability is high, by property preferably, is easy to microtubular to be deep into the distal end of blood vessel with the bending of blood vessel, it is easy to change head 1 Direction, reduces the operation difficulty of operation, while also mitigating the pain of patient.

Embodiment 2：As shown in fig. 6, the tube wall embeded guidewire 7 of microtubular, the end of seal wire 7 be arranged on the outside of inclined-plane 11 and Straight bevel facet 11 is set, remaining structure be the same as Example 1.When microtubular needs to enter distal end bifurcated vessels section 9, needed in conduit Seal wire 7 is set.Because distal operation difficulty is larger, seal wire 7 is played a supporting role to microtubular, while inclined-plane 11 can also be to leading Silk 7 travel directions regulation.Concretely comprise the following steps：Reverse microemulsion catheter tail 3, makes the inclined-plane 11 of catheter head 1 be directed at the blood to be entered Pipe, seal wire 7 is easier to stretch out microtubular head 1 along the vertical direction of inclined-plane 11, into purpose blood vessel, reduces the tune of direction of advance Whole difficulty, shortens operating time.

As shown in Figure 7 to 9, during microtubular insertion vascular occlusion section 8, by reverse microemulsion catheter tail 3, microtubular head is made Portion 1 rotates, and inclined-plane 11 produces machine cuts power, it is possible to increase microtubular is by the ability of thrombus part, when reducing sufferer operation Between, while the pain of sufferer is greatly reduced, so as to improve the success rate of vascular occlusion lesion.

As shown in Fig. 2 preferably, Marking ring 12 is gold material.Marking ring 12 is used to suffer from the distal end of microtubular Positioned in person's body, be easy to doctor more accurately to determine therapentic part, it is ensured that the security of operation.The selection of gold material, can be with The development effect for making Marking ring 12 preferably, is easy to doctor accurately to judge the position of microtubular head 1, entered beneficial to vascular lesion position Row dredging or further deep treatment.

The reasonable in design of microtubular, it is easy to operate, it is easy to by tortuous, narrow blood vessel, especially leads to microtubular The ability for crossing inaccessible section is greatly improved, while reducing the friction of microtubular and vascular wall, reduces the damage to vascular wall, is dropped Low operating difficulty, dramatically reduces the slight illness of patient, with good clinical therapeutic efficacy.
