An auxiliary device for rapid docking of blood vessels during operation

Abstract

The invention relates to an intra-operative rapid blood vessel butt-joint assisting device which comprises a lining ring and long-rod diameter expanding pliers. The lining ring is formed by bending a long-strip-shaped sheet, one end of the long-strip-shaped sheet is provided with a clamp spring, the other end of the long-strip-shaped sheet is provided with multiple clamping holes, and the clamp spring is inserted into the clamping holes to fix the diameter of the lining ring; the outer wall of the lining ring is provided with an upper groove and a lower groove; the head end of the long-rod diameter expanding pliers is provided with two rows of protrusions, and the lining ring is arranged between the two rows of the protrusions to feed the blood vessel and prevent slipping; a plier handle on one side is fixedly provided with a scale metering panel, the corresponding portion of a plier handle on the other side is fixedly provided with diameter reading lines, and the scale metering panel is provided with an anti-slip clamp hoop which can slide along the scale metering panel, so that excessive pressing and holding are prevented. According to the intra-operative rapid blood vessel butt-joint assisting device, butt-joint of the self-blood vessel and the artificial blood vessel can be changed into a binding fixing mode from a suture anastomosing mode, the blood vessel butt-joint operation time and the intra-operative circulatory arrest time can be significantly shortened, the operation difficulty is lowered, anastomotic bleeding and postoperative complications are reduced, and increasing of the survival rate of a patient and improving of the postoperative recovery quality are facilitated.

[0002] Aortic disease is a group of cardiovascular diseases that seriously threaten human health, mainly including aortic dissection and aortic aneurysm. Among them, aortic dissection is a catastrophic disease. If it is not treated in time, the prognosis is extremely dangerous. According to reports, the early mortality rate of untreated aortic dissection increased by 1% per hour, and more than 50% of patients died within 1 week. In recent years, the incidence of population aging, hypertension, and arteriosclerosis has increased. With the advancement of non-invasive medical imaging technology, the detection rate of such diseases has been increasing year by year. However, at present, the development of medical care in my country is uneven, and only a few hospitals c...
