Description

Interventional vascular hemostasis device for medical operation

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to an interventional vascular hemostasis device for medical surgery.

Background

In the interventional surgery of the current medical field, the puncture of the femoral artery and vein paths is most common, such as coronary artery formation and stent implantation, which are the common catheter interventional techniques for treating serious heart diseases. After the interventional operation is finished, the puncture on the arterial and venous blood vessels needs to be treated, and the treatment of the puncture on the venous blood vessels is simpler in general cases; the treatment of the puncture on the arterial vessel is complex, and the treatment method generally adopts a finger pressing method or a mechanical compression method to stop bleeding. The finger pressing method is difficult to grasp, arterial hemorrhage easily occurs if the pressing is too light, arterial thrombosis easily occurs in limbs if the pressing is too tight, hematoma can be generated at the puncture part even if the pressing is improper, and bluish violet and subcutaneous inclusion blocks with larger areas can be generated if the coagulation function of the patient is poor. In addition, because the finger pressing method needs to manually perform local hemostasis by compression on arterial blood vessels, the compression time is generally about half an hour, then the compression time is about 6 hours by using a sand bag, meanwhile, the limb on one side of the operation of a patient needs to be kept straight and braked for 12 hours, the patient can sit on the bed after 12 hours, the patient can not get out of the bed to move within 24 hours, and the urination and defecation of the patient are very difficult. The mechanical compression method is to use medical equipment to press the puncture part of the arterial vessel, but the method is inflexible to use, and is difficult to use freely according to different lesion positions of patients, so the mechanical compression method is less in use.

Along with the development of technology, the treatment of the puncture of arterial blood vessel by using a blood vessel suture device has been widely applied clinically. The general vascular suture device mainly comprises a contrast guide wire, a suture sheath, a needle injector, a pull rod, a knot pusher and the like, and has more related structures, so that the operation method is more complex, and the use steps of some vascular suture devices are even more than those of the general interventional operation, which results in that a doctor needs to spend much time to learn and be skilled. In addition, since the steps are numerous and the operation is complicated, medical accidents are also easy to occur.
