Description

Single-side combined coronary anastomosis and anastomosis method

The present invention relates to a tubular anastomosis device and an anastomosis method of an end-to-side connecting type, and more particularly, to an end-to-side connecting type coronary organ using an anastomosis ring. It relates to an anastomosis and an anastomosis method.

Due to lack of exercise and westernization of diet, the incidence of diseases of coronary organs (for example, blood vessels, large intestine, small intestine, etc.) among human organs is increasing year by year. In particular, most of the heart diseases are myocardial infarction and angina caused by the blockage of the blood vessels (Ischemia) that nourish and oxygenate the heart.

As a method of treating vascular or occluded blood vessels in which stenosis progresses, drug therapy and surgical therapy using muscle relaxants or anti-calcium agents that expand vascular muscles are used. Drug therapy is useful for the treatment of closed vessels in the early stages, but it is not a fundamental measure because the closure process is already very effective for the treatment of obstructive vessels of medium to longer term. Therefore, many surgical therapies, which are direct treatments for occluded blood vessels, have been performed.

Currently, surgical treatments include medical methods and surgical methods. The medical method is to insert a stent into the stenosis through blood vessels such as the femoral vein and inflate the stenosis by treating the stenosis. Devices required for methods of using such expanded metal meshes are disclosed in US Pat. No. 3,416,531 and the like. However, in this method, after a long time after surgery, the endometrial tissue grows through a metal mesh gap, and new granulation tissue grows inside the metal mesh, causing restenosis, which causes blood vessels to be blocked again. There is this.

Surgical methods, on the other hand, are a more fundamental solution: an incision in the chest and opening of the vessel (usually, the lower extremity veins) to bypass the blocked area. At this time, one end of the leg vein is connected to an internal mammary artery (IMA), an artery that supplies blood to the chest and abdominal tissues and muscles, or an end-to-end connection method. -Side connection method, and the other end is used to connect the blood vessel beyond the constriction site by a short-end connection, a short-side connection, or a side-to-side connection method. do.

The blood vessels are largely composed of the intima, the tunica media, and the adventitia. When the anastomosis of the two vessels occurs, the intima must be intima-to-intima contacted. In addition to the treatment of heart disease as described above, when reconstruction by flap transfer or anastomosis of the cut blood vessels, the microsurgical surgeon uses a suture to secure the enlarged field of view with a microscope or a high magnification magnifier and suture by hand. The method is mainly used. However, sutures can only be performed by highly skilled physicians and require a lot of time and effort. In particular, it is very difficult to suture the anastomosis of blood vessels in the region where the periodic rhythm is continuously performed, such as the heart. Therefore, during cardiac surgery, a procedure of artificially causing a heart attack for a long time (at least 3 hours or more) is necessary to stop the heartbeat.

Thus, a number of methods have been developed that allow physicians to fasten vascular anastomosis using a suture instead of using a suture instead of a fast anastomosis in a short time.

It is an object of the present invention to provide a single-side combined coronary anastomosis anastomosis method and anastomosis method that can easily and quickly anastomulate coronary organs (eg, blood vessels, colon, small intestine, etc.).

In the state in which the pipeline I is outward, the outer membrane of the pipeline I directly contacts the movable slider 54 (or the guide tube 10), and the inner membrane of the pipeline I is exposed to the outside on the contrary. At this time, when the first pressing ring 42 moves toward the moving ring 20, as described above, the separation distance between the moving ring 20 and the first pressing ring 42 is reduced ((d ₁ → d _2). , d ₁ > d ₂ ), the end of the conduit I may be fixed between the movable ring 20 and the first pressure ring 42. At this time, the first pressure ring 42 is the movable ring 20 Spaced apart from the predetermined distance (d ₂ ) to prevent the pipeline (I) from being damaged due to excessive compression, and the first pressure ring (42) instead of directly pressing the moving ring (20) second pressure ring ( 44 may indirectly press the moving ring 20 through the pressure pipe (30).

As shown in FIGS. 7 to 9, the movable slider 54 and the support bar 52 rotate in a direction perpendicular to the guide tube 10 as the movable ring 20 approaches the fixing ring 12. The angle formed by the movable slider 54 and the guide tube 10 changes as the separation distance between the fixed ring 12 and the movable ring 20 is changed by the movement of the movable ring 20. Such information can be easily understood through the folding and unfolding principle of an umbrella.

7 to 9, when the end of the conduit I is fixed between the movable ring 20 and the first pressure ring 42, when the dial 80 is continuously rotated, the pressure tube 30 is rotated. The pressurizing portion 22 connected to the rear end of the movable ring 20 can be continuously pressurized, whereby the movable ring 20 moves toward the stationary ring 12 fixed to the front end of the guide tube 10.

As shown in FIG. 15, the storage tube 60 is installed in front of the housing 70, and the storage tube 60 has a storage space 60b in which the anastomosis ring 90 is accommodated. The anastomosis ring 90 is accommodated in a direction substantially parallel to the longitudinal direction of the pressure tube 30 (or the guide tube 10), the pressure tube 30 (or guide tube 10) by the piston 64 to be described later. ) And are generally parallel to each other. As shown in FIG. 14, the anastomosis ring 90 has a plurality of fixing pins 92, and the fixing pins 92 are spaced apart by a predetermined interval along the circumference of the anastomosis ring 90.

The piston 64 is installed at the rear of the anastomosis ring 90 accommodated in the storage space 60b, and the piston 64 is connected to the connecting member 66. The connection member 66 may move along the movement space 60a formed at the rear of the accommodation space 60b to drive the piston 64. In this case, the length of the moving space 60a may substantially match the moving distance of the piston 64 (or the connecting member 66). On the other hand, the housing 70 has an upper passage 76 and the lower passage 78, the upper passage 76 and the lower passage 78 is formed in parallel with the moving direction of the receiving tube (60). The upper rod 67 is connected to the rear end of the receiving tube 60 to move together with the receiving tube 60, and the lower rod 68 is connected to the connecting member 66 to move together with the connecting member 66.

16 to 18 are views showing the operation of the storage tube and the piston shown in Figure 15, Figure 19 is a perspective view schematically showing a anastomosis ring modified in accordance with the operation of the piston shown in FIG. 20 is a view showing a state in which the pipeline I is fixed to the pipeline II through the anastomosis ring shown in FIG. 19.

As illustrated in FIG. 16, when the anastomosis ring 90 is stored inside the accommodating tube 60, the anterior anastomosis ring 90 is moved by moving the accommodating ring 60 toward the front. Close to the piston 64 moves with the receiving tube (60). The upper rod 67 and the lower rod 68 move along the upper passage 76 and the lower passage 78, respectively.
