Technical Field

The utility model relates to an artificial blood vessel technical field is a toper forked type artificial blood vessel.

Background

At present, the artificial blood vessels used for treating the abdominal aortic aneurysm and the abdominal aortic dissection by the vascular surgery open operation are all made of straight-tube bifurcation type terylene or Polytetrafluoroethylene (PTFE) materials, the diameter of the proximal end of the artificial blood vessel is 20mm at the maximum, and the diameter of the distal end of the artificial blood vessel is 10mm at the maximum, but the complicated condition that the abdominal aortic aneurysm merges the aortic dissection can be met in clinical work, the aneurysm neck is often large, some abdominal aortic aneurysm neck even exceeds 34mm, the existing artificial blood vessels cannot be matched with the large aneurysm neck, the artificial blood vessel with the diameter of 20mm at the upper end is forcibly sewn to the large aneurysm neck, the operation difficulty is increased, the operation time is prolonged, the death risk of a patient is increased, and the incidence rate of long-term complications is increased.

Disclosure of Invention

The utility model provides a toper forked type artificial blood vessel has overcome above-mentioned prior art not enough, and it can effectively solve current artificial blood vessel and be not convenient for adjust, problem that application scope is little.

The technical scheme of the utility model is realized through following measure: the utility model provides a toper branching type artificial blood vessel, includes trunk, left branch blood vessel and right branch blood vessel, and left branch blood vessel and right branch blood vessel outwards extend to trunk's lower extreme, and the diameter of trunk lower extreme is 20mm, and the diameter of trunk upper end is between 20mm to 34mm, and the length of trunk is between 50mm to 80 mm.

The following are further optimization or/and improvement of the technical scheme of the utility model:

the lengths of the left bifurcation blood vessel and the right bifurcation blood vessel can be between 100mm and 200 mm.

The diameters of the left bifurcation blood vessel and the right bifurcation blood vessel can be between 8mm and 10 mm.

The main blood vessel, the left branch blood vessel and the right branch blood vessel can be made of terylene materials.

The main blood vessel, the left branch blood vessel and the right branch blood vessel can be made of polytetrafluoroethylene materials.

The utility model has the advantages of reasonable and compact structure, simple manufacture sets up different diameters through the trunk vessel upper end, selects the artificial blood vessel of different specifications according to the size of abdominal aortic aneurysm neck, enables not unidimensional tumor neck and artificial blood vessel anastomose together, reduces the abdominal aortic aneurysm operation degree of difficulty of complicacy, shortens the time of performing the operation, makes patient's death risk reduce, can reduce the incidence of long-term complication simultaneously.

Drawings

Fig. 1 is a schematic sectional view of the preferred embodiment of the present invention.

The codes in the figures are respectively: 1 is a main blood vessel, 2 is a left bifurcation blood vessel, and 3 is a right bifurcation blood vessel.

Detailed Description

The utility model discloses do not receive the restriction of following embodiment, can be according to the utility model discloses a technical scheme and actual conditions determine concrete implementation.

In the present invention, for convenience of description, the description of the relative position relationship of the components is described according to the layout mode of the attached drawing 1 in the specification, such as: the positional relationship of front, rear, upper, lower, left, right, etc. is determined in accordance with the layout direction of the drawings of the specification.

The invention will be further described with reference to the following examples and drawings:

as shown in fig. 1, the tapered bifurcated artificial blood vessel comprises a main blood vessel 1, a left bifurcated blood vessel 2 and a right bifurcated blood vessel 3, wherein the lower end of the main blood vessel 1 extends outwards to form the left bifurcated blood vessel 2 and the right bifurcated blood vessel 3, the diameter of the lower end of the main blood vessel 1 is 20mm, the diameter of the upper end of the main blood vessel 1 is 20mm to 34mm, and the length of the main blood vessel 1 is 50mm to 80 mm. The length of the main blood vessel 1 may be 60mm, as required. In the use process, the diameters of the upper ends of the main blood vessels 1 are between 20mm and 34mm, and the artificial blood vessels with different specifications are selected according to the sizes of the abdominal aortic aneurysm neck, so that the aneurysm necks with different sizes can be anastomosed with the artificial blood vessels, the difficulty of complex abdominal aortic aneurysm operation is reduced, the operation time is shortened, the death risk of patients is reduced, and the incidence rate of long-term complications can be reduced.

The tapered bifurcation artificial blood vessel can be further optimized or/and improved according to the actual needs:

as shown in fig. 1, the lengths of the left and right bifurcated vessels 2 and 3 are each between 100mm and 200 mm. The lengths of the left and right bifurcated vessels 2 and 3 may be 150mm, as required.
