Combined type micro vessel anastomat

Abstract

The invention discloses a combined type micro vessel anastomat which comprises a circular ring, side columns, a sterilization film and a pressure sensor, wherein the side columns are movably connected to the periphery of the circular ring; the sterilization film is arranged at the periphery of the inner diameter of the circular ring; the pressure sensor is embedded to one end of the inner part of the circular ring. According to the combined type micro vessel anastomat, the situation that vessels are squeezed by external force can be prevented, and the vasospasm is avoided, so that vessels are kept smooth; besides, the endangium is kept to turn outwards to prevent vessel twist and keep vessel orifices stagger; moreover, secondary harm and pain of patients can be relieved by virtue of the circular ring made of an absorbing material.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a combined microvascular stapler. Background technique [0002] In addition to the arterial-capillary-venous communication, the blood vessels of the human body can directly communicate with each other between arteries, veins, and even arteries and veins to form vascular anastomosis. Many parts or organs in the human body The two arterial trunks can be connected by communicating branches (such as between the base of the brain artery). In the frequently active or vulnerable parts, the multiple adjacent arterial branches often anastomose with each other to form an arterial network (such as the joint network). For organs that change shape, the ends of two arteries or their branches can be directly anastomosed to form arterial arches (such as deep palmar arch, superficial palmar arch, lesser curvature arterial arch, etc.). These anastomoses have the effect of shortening the...

Problems solved by technology

In addition, there is a special form of arterial anastomosis in the kidney, that is, the miraculous rate, which is different from the general connection sequence of arteries, capillaries, and veins, but small arteries, arterial capillaries, and then Converge into small arteries, the network is full of arterial blood, its function is unknown, the microvascular staplers on the market can not prevent the extrusion of blood vessels by external force well, prone to vasospasm, can not guarantee the smooth flow of blood vessels, most of the staplers It will bring secondary harm and pain to the patient
