[0002] Coronary artery bypass surgery requires anastomosis of the internal mammary artery with the coronary artery. The internal mammary artery is thin and soft, and an assistant needs to use two forceps to fix it to expose the anastomosis. The disadvantage of this exposure method is that it lacks stability, and the process of trimming the stump of the internal mammary artery and anastomosis during minimally invasive bypass surgery can only be performed in the chest cavity, which greatly increases the difficulty of exposure and is no longer suitable for assistants.

[0003] Therefore, it is expected to provide a new technical solution for fixing the internal mammary artery. Summary of the invention

[0006] Preferably, the flexible material pad is a silicone pad.

[0007] Preferably, the length of the flexible material arm is not less than half of the width of the flexible material pad, so that the external magnetic sheets on both sides of the flexible material pad can cover the entire width range of the flexible material pad.

[0009] Preferably, the distance between the external magnetic sheets on the same side is no more than twice the length of the flexible material arm, so that the external magnetic sheets can cover the entire length range of the flexible material pad.

[0010] Preferably, built-in magnetic sheets are evenly arranged on the entire flexible material pad.

[0011] Preferably, the vascular anastomosis auxiliary fixation soft magnetic plate is used in coronary artery bypass surgery.

[0012] Preferably, the vascular anastomosis auxiliary fixation soft magnetic plate is used to fix the tissue around the internal mammary artery arranged on the flexible material pad through the attraction between the external magnetic sheet and the internal magnetic sheet.

[0022] Figure 1 The schematic diagram of the unfolded structure of the soft magnetic plate for auxiliary fixation of vascular anastomosis according to the preferred embodiment of the present invention is schematically shown.

[0023] like Figure 1 As shown, the vascular anastomosis auxiliary fixation soft magnetic plate according to the preferred embodiment of the present invention includes: a flexible material pad 10, an external magnetic sheet 20 and an internal magnetic sheet 30, wherein the external magnetic sheet 20 is connected to the flexible material pad 10 through a flexible material arm 40, and the internal magnetic sheet 30 is arranged on the flexible material pad 10; when not in use, the flexible material arm 40 is unfolded to keep the magnetic pole directions of the external magnetic sheet 20 and the internal magnetic sheet 30 consistent, so that the external magnetic sheet 20 and the internal magnetic sheet 30 will not attract each other due to magnetism; when in use, the flexible material arm 40 is bent toward the flexible material pad 10 and the magnetic pole of the external magnetic sheet 20 is flipped up and down, so that the external magnetic sheet 20 and the internal magnetic sheet 30 are close to each other and the external magnetic sheet 20 and the internal magnetic sheet 30 are attracted to each other due to magnetism.

[0024] For example, when the flexible material arm 40 is unfolded so that the flexible material pad 10 and the external magnetic sheet 20 are in the same plane (for example Figure 1 In the state shown in the figure, the magnetic pole directions of the external magnetic sheet 20 and the internal magnetic sheet 30 are consistent, so that the external magnetic sheet 20 and the internal magnetic sheet 30 will not attract each other due to magnetism. In this way, the entire vascular anastomosis auxiliary fixation soft magnetic plate can be kept stable in the unused state.

[0025] Moreover, for example, when in use, when the flexible material arm 40 is turned over and bent (the magnetic poles of the external magnetic sheet 20 are also turned over), the external magnetic sheet 20 and the internal magnetic sheet 30 are attracted to each other due to magnetism when they are close to each other (for example, Figure 2 status shown).

[0026] Preferably, the flexible material pad 10 is a silicone pad.

[0027] Preferably, the length of the flexible material arm 40 is not less than half of the width of the flexible material pad 10 , so that the external magnetic sheets 20 on both sides of the flexible material pad 10 can cover the entire width range of the flexible material pad 10 .

[0028] Preferably, two or more external magnetic sheets 20 are arranged on both sides of the flexible material pad 10 .

[0029] Preferably, the distance between the external magnetic sheets 20 on the same side of the flexible material pad 10 is no more than twice the flexible material arm 40 , so that the external magnetic sheets 20 can cover the entire length range of the flexible material pad 10 .

[0030] Preferably, the built-in magnetic sheets 30 are evenly arranged on the entire flexible material pad 10. Thus, different areas can be easily fixed.

[0031] Preferably, the built-in magnetic sheet 30 is embedded in the flexible material pad 10. Of course, the built-in magnetic sheet 30 can also be arranged on the surface or back of the flexible material pad 10.

[0032] Preferably, the soft magnetic plate for auxiliary fixation of blood vessel anastomosis according to the preferred embodiment of the present invention is used in coronary artery bypass surgery. Of course, the present invention can also be used in any other occasions where tissue fixation is required.

[0033] For example, the vascular anastomosis auxiliary fixation soft magnetic plate according to the preferred embodiment of the present invention is used to fix the tissue around the internal mammary artery arranged on the flexible material pad 10 through the attraction between the external magnetic sheet 20 and the internal magnetic sheet 30 .

[0034] In a specific embodiment, Figure 2 As shown, by using the above device, the internal mammary artery can be laid flat on the magnetic plate and the position of the external magnetic plate can be adjusted to fix the tissue 60 (such as fat, muscle tissue) around the internal mammary artery 50 on both sides, thereby exposing the arterial anastomosis.

[0035] Therefore, the present invention provides a soft magnetic plate for auxiliary fixation of vascular anastomosis, which can effectively solve the problem that the internal mammary artery cannot be stably exposed during coronary artery bypass grafting, especially minimally invasive bypass grafting, significantly improve the clarity of the surgical field, reduce the difficulty of surgery, and improve the quality of surgery.
