DEVICE FOR simultaneously clamping abdominal aortic lumbar and sacral arteries

摘要

A device for simultaneous clamping of the abdominal aorta, lumbar and sacral arteries relates to medicine and can be used for clamping the abdominal aorta, sacrum and lumbar arteries during surgical treatment of occlusive diseases of the abdominal aorta, abdominal aortic wounds. The purpose of this unit - a technically simple clamping of the abdominal aorta, the sacrum and lumbar arteries at reconstructive operations on the aorta. The goal is achieved vascular clamp structure. The design of the clamp allows the pinch proximal abdominal aorta, lumbar and sacral artery without clamping of the distal aorta and iliac arteries. This clip has three corners in lateral projection. The first angle 125 degrees, it is necessary to remove the clamp from operating handles wound area, for better visualization main object operation. The second angle 110 degrees, it is necessary to introduce into the cavity of the wound clip and places Branche under clamping the aorta, the angle of 110 degrees to bring the clamp design allows the axis of projection of the operative action. The third angle 130 degrees needed for compression of the proximal end of the abdominal aorta. A distinctive feature of the clamp is the presence of three corners and two semi-circles formed by the main clamping jaws in a direct projection. Semicircle circle formed during closure clip Branche thus closing in the art Branche occurs. The diameter of the circle of 2 centimeters. When clamping Branche institution under the aorta with a view to clamping the lumbar arteries circumference fits the terminal aorta or initial parts of the common iliac arteries, but due to the tip of the clamping angle is clamping the proximal aorta. Thus, the clamping of the aorta and the common iliac arteries does not occur, which is very important in patients with severe calcification of the aorta and iliac arteries.
