Problems solved by technology

[0007] The problem with OPCAB and MIDCAB is that due to the beating heart of the operation, it is difficult to achieve a perfect joint in a short time
The disadvantage of this method is that the force of clamping the coronary artery cannot be controlled
However, in this attempt, the coronary artery itself was damaged due to the use of a needle to pass the thread through the heart muscle; moreover, since the heart muscle was clamped by the thread, it was uncertain how much clamping force would be required to ensure interruption of blood circulation

Embodiment Construction

[0035] Best Mode for Carrying Out the Invention

[0036] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0037] The present invention consists of three components, namely base pad 11, infusion tube 20 and occluder 30, and shows the best results when all components are used. It is also possible to choose to use two or one part. Each component is described below. base pad

[0038] figure 2 One side of the base pad (11) shown in is provided with a sealing portion (14); perforations (13) are located on both sides of the sealing portion (14); laces (12) are used to fix the base pad on the outside of the surgical site , so that during the use of the base pad, the position of the base pad will not change due to the beating of the heart. In this embodiment, there are two through holes (13), but the number of through holes may not be limited to two. In some cases, the sealing part (14) or the through hole (13) may not b...

Abstract

An auxiliary device for safely and surely performing off-pump coronary artery anastomosis and low-invasive coronary artery bypass. This device consists of a means for elevating the heart to enable an operator to see the anastomosed part directly in the face and, at the same time, achieving the static state of the anastomosed part; a means for perfusing the blood in the peripheral side of the coronary artery during the anastomosis of a blood vessel for bypass; and a means for fastening the coronary artery in the central side and in the peripheral side of the anastomosed part of the coronary artery to thereby block the blood flow, thus maintaining the anastomosed part in a blood-free state.

Description

technical field [0001] The present invention relates to a device for engaging a coronary bypass graft on a beating heart. Background technique [0002] In recent years, the treatment of coronary artery vasodilation using a stent implanted in the cardiovascular system as a catheter or catheter release has been rapidly applied to patients with ischemic heart diseases (such as myocardial infarction) and their hearts Patients who are still functioning relatively well. This method of treatment is characterized by less invasiveness to the patient and a shorter hospitalization period, but there are problems in that repeated stenosis often occurs and the attendant high cost. [0003] Meanwhile, in addition to catheter therapy, a coronary artery bypass graft (hereinafter referred to as CABG) is also used in actual treatment. The method, which involves exposing the heart and attaching a shunt graft used to deliver blood from another vessel in a heart with a narrowing of the coronary...
