Embodiment Construction
[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0014] Such as Figure 1 to Figure 2 As shown, the bidirectional vascular guide sheath includes a sheath tube assembly and a sheath core assembly 2. The sheath tube assembly includes a sheath tube 1 and a sheath tube attachment 4. The sheath tube 1 is provided with a through sheath tube lumen, and the rear part of the sheath tube 1 is connected to the sheath tube Attachment 4, the sheath core assembly 2 is inserted into the sheath tube lumen from the sheath tu...

The invention provides a bidirectional blood vessel guiding sheath, belongs to the technical field of medical instruments, and aims to overcome the defects that blood vessel guiding sheaths commonly used in the market are all one-way, and when bilateral superficial femoral artery lesions are treated at the same time, bilateral approach needs to be conducted at the same time, and two puncture points are left. The bidirectional blood vessel guiding sheath comprises a sheathing canal assembly and a sheathing core assembly, the sheathing canal assembly comprises a sheathing canal and a sheathing canal accessory, the sheathing canal accessory is connected to the rear portion of the sheathing canal, the front end of the sheathing canal is split into two semicircular sheathing pieces in the axial direction of the sheathing canal, and elastic metal wires are arranged in the canal walls of the semicircular sheathing pieces. A split structure is arranged at the front end of the original sheathing canal, so that the sheath can be used as a common guiding sheath, and when bilateral limb lesions exist at the same time, the lesions can be simultaneously solved at the same puncture point, so that the number of puncture parts in a vascular operation is reduced, the pain of a patient is relieved, and the occurrence rate of postoperative complications can be reduced.
Description
technical field [0001] The invention relates to the technical field of medical appliances, in particular to a bidirectional blood vessel guiding sheath. Background technique [0002] Vascular catheter is a necessary surgical instrument for endovascular surgery. Through the guide sheath indwelling in the blood vessel, surgical instruments such as guide wire / catheter / balloon and stent can be sent, so as to achieve no damage to the vessel wall and less surgical bleeding And so on. At present, the common vascular guide sheaths in the domestic and international markets are unidirectional puncture reserved vascular guide sheaths. When dealing with bilateral superficial femoral artery lesions at the same time, bilateral approaches are required, which increases the pain of the patient, increases the operation time and difficulty, and is prone to postoperative bleeding at the puncture site, pseudoaneurysm, arteriovenous fistula, and deep vein thrombosis of the lower extremities and...
