Large-diameter vascular intervention therapy incision suture device

Abstract

The invention relates to a large-diameter vascular intervention therapy incision suture device. The device comprises a shell body, a strippable guide sheath, a catheter, guiding bases, a guide needle set with a suture, a suture-free guide needle set and a bridge passing suture; the strippable guide sheath is provided with a tearing part and a cutting line, the two guiding bases are arranged, and a spheroid separating block capable of making the guiding bases separated or gathered together is arranged between the guiding bases; two guide needles with the suture and two suture-free guide needles are arranged and correspond to the guiding bases one to one. According to the device, by adopting the double-needle design, a suture incision can be sutured twice through one-time needle insertion operation; the suturing effect is better, and the consistency is higher; the operation steps are reduced, therefore the operation risk is reduced, and the pain and medical cost brought to a patient are reduced. In addition, the strippable guide sheath is adopted, it is only required that the strippable guide sheath is torn by one hand, the suture can be in orderly arrangement and can be conveyed for knot tying, therefore the operation steps are reduced, the operation efficiency is improved, and the safety is improved.

Description

technical field [0001] The invention relates to the field of vascular suturing devices, in particular to a suturing device for large-diameter vascular interventional treatment ports. Background technique [0002] In recent years, the diagnosis and treatment technology of percutaneous coronary intervention has been developed rapidly at home and abroad, but the use of artificial or mechanical compression to stop bleeding after surgery is prone to bleeding, hematoma, arterio-venous atrophy, pseudoaneurysm, and vasovagal reflex. Various complications such as transfemoral artery and coronary intervention have been plagued by nursing and recovery after diagnosis and treatment of coronary artery. At present, the method of using vascular suturing device for hemostasis can make up for the drawbacks brought by the conventional method of hemostasis; however, the size of the wound that can be sutured by the conventional vascular suturing device is less than 12Fr; if the wound is too lar...

Problems solved by technology

[0002] In recent years, percutaneous coronary intervention diagnosis and treatment technology has been developed rapidly at home and abroad, but manual or mechanical compression hemostasis after surgery is prone to bleeding, hematoma, arteriovenous fistula, pseudoaneurysm, vasovagal reflex, etc. Nursing and recovery after transfemoral artery and coronary intervention diagnosis and treatment

At present, the method of using blood vessel suture device for hemostasis makes up for the disadvantages caused by conventional hemostasis methods; however, the size of the wound that can be sutured by conventional blood vessel suture device is below 12Fr; if the wound is too large, two blood vessel suture devices are required Performing two sutures not only increases the cumbersomeness of the operation, but also increases the risk; it also increases the pain of the patient and the cost of the operation
