Description

Quick anastomosis device for blood vessels

Technical Field

The utility model relates to a medical field, concretely relates to quick identical device of blood vessel.

Background

Vascular anastomosis, i.e. an operation for reconstructing blood circulation by suturing the severed ends of blood vessels, is one of the common operations in modern clinical operations and is often applied to cases such as flap transplantation, blood vessel trauma, heart bypass and the like. At present, most of clinical vascular anastomosis adopts direct manual suturing, and the vascular anastomosis technology usually requires professional training and long-time practice of operators, so that high vascular anastomosis success rate is ensured, and the required learning time is long. Meanwhile, the operator needs to have strong physical and psychological qualities to deal with the high-intensity operation (long operation time, high concentration and visual vertigo discomfort caused by long-time use of a microscope).

In some operations, such as severe hand trauma, because many vascular anastomoses are needed to be anastomosed, in order to ensure the survival of limbs, arteries and veins need to be sutured as many as possible, which often takes a lot of time and energy, and the operation time is greatly prolonged, thereby increasing the risk of surgical infection and prolonging the ischemic time of severed limbs, and finally causing the infection and necrosis of the severed limbs.

Secondly, certain procedures place high demands on the quality of vascular anastomosis. Due to the high pressure born by the blood vessel, bleeding and bleeding often occur at the local part of the anastomotic stoma after anastomosis, the hemostasis is difficult, peripheral hematoma formation occurs at a low rate, and a major bleeding risk occurs at a high rate. In addition, the vascular anastomotic stoma causes vascular stenosis due to scar formation, easily causes thrombosis or vascular blockage and reclosure, and causes accidents.

Therefore, a new vascular anastomosis device is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that current blood vessel coincide needs to be sewed up, and bleeding oozing blood can appear in the part of coincide mouth, not only is difficult for stanching, the operation difficulty to availability factor is lower, and aim at provides a quick anastomotic device of blood vessel, solves the anastomotic problem of blood vessel.

The utility model discloses a following technical scheme realizes:

a blood vessel fast anastomosis device comprises an inner fixing ring connected on the inner walls of two disconnected first blood vessels and second blood vessels, wherein the outer walls of the first blood vessels and the second blood vessels are sequentially sleeved with the first fixing ring and the second fixing ring from the anastomosis end to the other end;

the inner ring of the first fixing ring is provided with a plurality of anastomotic thorns, and when the inner fixing ring is everted and positioned on the outer wall of the blood vessel, the anastomotic thorns on the first fixing ring pierce the blood vessel;

the second fixing ring is connected with an inverted hook; the anastomotic ends of the first blood vessel and the second blood vessel are connected on a second fixing ring clamped on the other blood vessel through barbs.

Further, this device is when using, at first fix the inside at first blood vessel and second blood vessel respectively with interior solid fixed ring, first solid fixed ring and the solid fixed ring suit of second are on vascular outer wall, when will inosculate, turn up the interior solid fixed ring of intravascular portion, make interior solid fixed ring be located hematal outer wall, then place interior solid fixed ring in first solid fixed ring department again, interior solid fixed ring makes the identical thorn on the first solid fixed ring pierce through the vascular wall that turns up, and then fix a position this device, make this device fix on blood vessel, then the overhead kick block on the solid fixed ring of second on two blood vessels of rethread is on the solid fixed ring of second that corresponds, provide pressure, and then realize the identical of two blood vessels.
