Description

Sheath tube for neck blood vessel and external connection kit

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to a sheath pipe and external connection external member for neck blood vessel.

Background

The cerebrovascular interventional operation is mainly to puncture and place a tube from a femoral artery, because the femoral artery is bigger and shallower, the puncture is easy, and the hemostasis is easy to be pressed or the hemostasis is easy to be sewed by an intravascular suturing device after the operation is finished; in recent years, the technology of the intravascular treatment of the intracranial venous system is advanced, the lesion of the intracranial venous system of a patient can be displayed by femoral artery puncture radiography, and then a catheter is punctured from the femoral vein, and a device is placed in the catheter to perform interventional treatment on the lesion part of the intracranial venous system.

The vessel is inserted into the cerebral vessels from the femoral artery or the femoral vein, the vessel to be treated is reached from the puncture point, the vessel needs to enter different vessel cavities, the path of the vessel is long, and the insertion equipment has enough supporting force and good operation performance, so that the insertion equipment which can be selected is limited, the implementation of the optimal treatment scheme is limited, and the operation difficulty of an operator is increased; the blood vessel path is long and tortuous, particularly under the condition of a three-type aortic arch, the interventional treatment is carried out on the cerebral vessels, the advancing angle of the guide wire catheter along the blood vessel path is too large, and even if the supporting force and the control performance are good, the guide wire catheter cannot reach the pathological change part needing to be treated, and the interventional operation treatment cannot be smoothly finished under the condition; the key of the intravascular treatment of the acute ischemic stroke lies in opening blocked blood vessels as early as possible and saving ischemic penumbra, so that the treatment time is saved as one of the keys of success and failure of the operation, the adverse factors such as long path and tortuosity on the femoral artery puncture method can cause the extension of the treatment time, and even the interventional equipment cannot reach the position of the blood vessel blockage due to factors such as large angle; in the interventional therapy process of an intracranial venous system, the femoral vein puncture is adopted, and due to the factors of long blood vessel access, thin and irregular wall of an intracranial venous tube and the like, the difficulty of reaching a lesion position by a device and the risk of puncturing the blood vessel wall by an interventional guide wire are increased.
