[0001] The present invention belongs to the technical field of cardiac surgery, and in particular relates to a cardiac suspension mechanism and a method of using the same. Background Art

[0002] During cardiac surgery and rehabilitation treatment of heart disease, fixation and suspension of the heart are crucial. Proper fixation and suspension can effectively reduce the burden on the heart, maintain the heart's relatively appropriate position in the body, create a good operating field for surgery, and improve the success rate of surgery.

[0003] Currently, traditional methods and devices are primarily used clinically to fix and suspend the heart and chest area. Simple suspension wires and cardiac stabilizers are the most common. However, these traditional methods have significant limitations. Simple suspension wires are difficult to achieve satisfactory suspension effects and often require additional assistance. Cardiac surface stabilizers are commonly used, but their use can significantly damage the epicardium due to the high pressure required for adsorption. This is particularly true during surgery on elderly patients, whose epicardium is fragile and prone to bleeding, leading to cardiac hematoma and even cardiac rupture. Therefore, a cardiac suspension mechanism and method for its use are proposed. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figure 1-5 As shown, a heart suspension mechanism comprises:

[0034] Two connecting plates 1, with a plurality of first connecting belts 2 connected to opposite sides of the two connecting plates 1;

[0035] Multiple fixing straps 3 and multiple second connecting straps 4 are used to fix the patient's heart area. One side of the fixing strap 3, the first connecting strap 2 and the second connecting strap 4 is provided with Velcro, and the fixing strap 3 is connected to the first connecting strap 2 and the second connecting strap 4 by Velcro;

[0036] As can be seen from the above, when the staff performs cardiac surgery on the patient, they first place the two connecting plates 1 in a suitable position, and the multiple first connecting belts 2 connected to the opposite sides of the two connecting plates 1 play a preliminary connection and positioning role. Then, multiple fixing belts 3 and multiple second connecting belts 4 are used to fix the patient's heart. Since one side of the fixing belt 3, the first connecting belt 2 and the second connecting belt 4 are all provided with Velcro, the staff can flexibly adjust the connection position of the fixing belt 3 by adjusting the connection position of the Velcro on the first connecting belt 2 and the second connecting belt 4 and the fixing belt 3 according to the specific situation of the patient's surgery, ensuring that the fixing belt 3 can accurately fit the different positions on the patient's heart that need to be fixed, providing a stable fixation foundation for subsequent suspension operations;

[0037] Through the arrangement of the above technical solution, the multiple first connecting straps 2 connected to the opposite sides of the two connecting plates 1 are used in conjunction with the multiple fixing straps 3 and the second connecting straps 4 to provide flexible adjustment space for the fixation and maintenance of the patient's heart area. The Velcro provided on one side of the fixing strap 3, the first connecting strap 2, and the second connecting strap 4 enables the fixing strap 3 to be easily connected to the first connecting strap 2 and the second connecting strap 4 through the Velcro, and the connection position of the fixing strap 3 can be freely adjusted according to the different positions and actual needs of the patient's surgery. This design fully takes into account the individual differences of the patients, such as body shape, heart position, and condition, and can accurately adjust the fixing strap 3 to the most suitable position, providing the patient with a personalized fixation and suspension solution, ensuring that the fixation effect is optimal, and effectively improving the success rate of the operation and the quality of recovery;

[0038] like Figure 1-5As shown, a traction and reeling mechanism is used to connect multiple fixing belts 3 with the card seat for use. The traction and reeling mechanism is located on the connecting plate 1. The traction and reeling mechanism includes multiple installation boxes 5 installed on one side of the connecting plate 1. The interior of the installation box 5 is rotatably connected to a reeling roller 501, and the top of the reeling roller 501 rotates and extends to the outside of the installation box 5. The top of the installation box 5 is fixedly connected to a fixed disk 502, and the inner side of the fixed disk 502 is connected to a torsion spring 503. The outer wall of the reeling roller 501 is located inside the installation box 5 and is wound around a suspension rope 504, and one end of the suspension rope 504 slides and extends to the outside of the installation box 5.

[0039] The present invention is further specifically described. A rotation groove is provided on the top of the installation box 5. One end of the winding roller 501 rotates through the rotation groove and extends to the outside of the installation box 5. A sliding hole is provided on one side of the installation box 5. One end of the suspension rope 504 slides through the sliding hole and extends to the outside of the installation box 5. The end of the torsion spring 503 away from the fixed plate 502 is connected to the outer wall of the installation box 5, and the torsion spring 503 is sleeved on the outer wall of the winding roller 501.

[0040] As can be seen from the above, the traction and winding mechanism is located on the connecting plate 1, and is mainly composed of multiple installation boxes 5 installed on one side of the connecting plate 1 and their internal components. The installation box 5 is rotatably connected to the winding roller 501, and the top of the winding roller 501 rotates and extends to the outside of the installation box 5, which is convenient for the staff to operate. The top of the installation box 5 is fixedly connected to the fixed disk 502, and the inner side of the fixed disk 502 is connected to the torsion spring 503. The end of the torsion spring 503 away from the fixed disk 502 is connected to the outer wall of the installation box 5 and is sleeved on the outer wall of the winding roller 501. The winding roller 50 The outer wall of 1 is located inside the installation box 5 and is wound with a suspension rope 504. One end of the suspension rope 504 slides through a sliding hole opened on one side of the installation box 5 and extends to the outside of the installation box 5. When the fixing belt 3 needs to be suspended, the staff pulls the suspension rope 504 extending to the outside of the installation box 5. The suspension rope 504 drives the winding roller 501 to rotate inside the installation box 5. At this time, the torsion spring 503 is deformed to store elastic potential energy. In this way, the staff can adjust the length of the suspension rope 504 according to actual needs to adapt to different suspension height and angle requirements.

[0041] When the sling 504 is released, the torsion spring 503 recovers its deformation, driving the reel 501 to automatically rotate and reel the sling 504 back into the installation box 5. This automatic reeling function is not only easy to operate, but also can quickly adjust the length of the sling 504 to meet the needs of use in different scenarios, thereby improving work efficiency.

[0042] It should be noted that the end of the suspension rope 504 away from the winding roller 501 is connected to a cardiac stabilizer. The cardiac stabilizer mechanically stabilizes the heart during on-beat bypass surgery, reducing the amplitude of movement caused by the beating heart and providing the surgeon with a relatively static surgical field of view. By adjusting the length of the suspension rope 504, the staff can adjust the suspension height and angle of the heart for different patients. The cardiac sling is mainly used to suspend the heart for circumflex coronary artery bypass and right coronary artery bypass surgery.

[0043] like Figure 1-5 As shown, the traction locking mechanism is used to lock and fix the suspension rope 504 of the traction and winding mechanism after it is pulled. The traction locking mechanism is located inside the installation box 5. The traction locking mechanism includes a limiting slide 603 provided at the bottom of the inner wall of the installation box 5. The inner part of the limiting slide 603 is connected to the limiting cross bar 604. The outer wall of the limiting cross bar 604 is slidably connected to the limiting magnetic block 605. The limiting magnetic block 605 is rotatably connected to the rotating shaft 6. A square slide 601 is provided on the top of the installation box 5. The rotating shaft 6 and the outer wall of the winding roller 501 are fixedly connected with a locking gear 602. Both sides of the inner wall of the limiting slide 603 are fixedly connected with mounting magnetic plates 606.

[0044] The present invention further specifically details that the outer wall of the limiting magnetic block 605 and the inner wall of the limiting chute 603 are slidingly fitted, the top of the rotating shaft 6 extends to the outside of the mounting box 5 through the square chute 601, the limiting magnetic block 605 and the mounting magnetic plate 606 are arranged to attract each other with corresponding opposite poles, and the two locking gears 602 are fully meshed;

[0045] As can be seen from the above, the traction locking mechanism is arranged inside the installation box 5, which is used to lock and fix the suspension rope 504 after traction. The mechanism includes a limiting slide 603 provided at the bottom of the inner wall of the installation box 5, the inner part of the limiting slide 603 is connected to the limiting cross bar 604, and the outer wall of the limiting cross bar 604 is slidably connected to the limiting magnetic block 605. The outer wall of the limiting magnetic block 605 and the inner wall of the limiting slide 603 are slidably fitted to ensure that the limiting magnetic block 605 can be stably in the limiting slide 603. The inner sliding, limiting magnetic block 605 is rotatably connected to the rotating shaft 6, and the top of the rotating shaft 6 extends to the outside of the installation box 5 through the square slide 601 opened on the top of the installation box 5, which is convenient for the staff to operate. The rotating shaft 6 and the outer wall of the winding roller 501 are fixedly connected with the locking gear 602, and the two locking gears 602 are fully meshed. The inner walls of the limiting slide 603 are fixedly connected with the mounting magnetic plate 606 on both sides. The limiting magnetic block 605 and the mounting magnetic plate 606 are set to attract each other with opposite poles.

[0046] When the staff adjusts the suspension rope 504 to a suitable length, they push the limiting magnet 605 so that it attracts the opposite poles of the mounting magnetic plate 606 on one side of the limiting slide 603. At this time, the limiting magnet 605 drives the rotating shaft 6 to move, so that the two locking gears 602 are tightly meshed, thereby locking the rotation of the winding roller 501, and then locking and fixing the pulled suspension rope 504 to ensure the stability of the heart and cardiothoracic area during the suspension process. When it is necessary to release the suspension rope 504, the staff pushes the limiting magnet 605 so that it attracts the opposite poles of the mounting magnetic plate 606 on the other side of the limiting slide 603. At this time, the two locking gears 602 are disengaged, and the winding roller 501 automatically rotates under the elastic force generated by the recovery deformation of the torsion spring 503, and rewinds the suspension rope 504 back into the installation box 5;

[0047] By setting up the above technical scheme, the traction locking mechanism inside the installation box 5 realizes the precise locking and release of the suspension rope 504 through the coordinated action of the limiting slide 603, the limiting cross bar 604, the limiting magnetic block 605, the rotating shaft 6 and the locking gear 602. When the limiting magnetic block 605 and the mounting magnetic plate 606 on one side of the limiting slide 603 are attracted by opposite poles, the two locking gears 602 are fully engaged, which can effectively lock the suspension rope 504 after traction, ensure the stability of the heart and the cardiothoracic area during the fixed suspension process, and avoid If an accident occurs due to the loosening of the suspension rope 504, when the suspension rope 504 needs to be released, it is only necessary to move the limiting magnetic block 605 to a position where the opposite poles of the mounting magnetic plate 606 on the other side of the limiting slide 603 are attracted. The two locking gears 602 are disengaged, and the suspension rope 504 is automatically reeled according to the rotation of the reeling roller 501 and the torsion spring 503. This precise locking and releasing function is simple and convenient to operate, and the state of the suspension rope 504 can be adjusted at any time according to actual needs, providing a reliable guarantee for cardiac suspension operation.

[0048] like Figure 1-5 As shown, the lubrication mechanism is used to lubricate the traction locking mechanism. The lubrication mechanism is located inside the installation box 5 and includes two lubrication boxes 7 installed inside the installation box 5. The interiors of the two lubrication boxes 7 are rotatably connected to lubrication rollers 701, and one side of the lubrication rollers 701 rotates and extends to the outside of the lubrication boxes 7.

[0049] The present invention further specifically details that the lubrication roller 701 and the outer side wall of the locking gear 602 are frictionally engaged, the rotation directions of the lubrication roller 701 and the locking gear 602 are arranged in the same direction, and a feed hole is opened on the top of the lubrication box 7, and the feed hole extends to the outside of the mounting box 5;

[0050] As can be seen from the above, the lubrication mechanism is also arranged inside the installation box 5, which is used to lubricate the traction locking mechanism to reduce friction and wear between components and extend the service life of the equipment. The mechanism includes two lubrication boxes 7 installed inside the installation box 5. The interiors of the two lubrication boxes 7 are rotatably connected to lubrication rollers 701, and one side of the lubrication roller 701 rotates and extends to the outside of the lubrication box 7. The lubrication roller 701 and the outer wall of the locking gear 602 are frictionally fitted, and the rotation direction of the lubrication roller 701 and the locking gear 602 are the same. During the rotation of the locking gear 602, the lubrication roller 701 and the locking gear 602 rub against each other, thereby applying the lubricant in the lubrication box 7 to the locking gear 602 to play a lubricating role. A material inlet hole is provided at the top of the lubrication box 7, and the material inlet hole extends to the outside of the installation box 5, which is convenient for staff to add lubricant to the lubrication box 7. A material outlet is provided at the bottom of the installation box 5 for discharging the lubricant scattered from the lubrication box 7 to prevent the lubricant from accumulating in the installation box 5 and affecting the normal operation of the equipment.

[0051] Through the setting of the above technical solution, the lubrication mechanism inside the installation box 5 provides continuous lubrication for the traction locking mechanism through the two lubrication boxes 7 and the internally rotatably connected lubrication roller 701. The lubrication roller 701 is frictionally fitted with the outer wall of the locking gear 602 and rotates in the same direction. During the rotation of the locking gear 602, the lubricant can be automatically applied to the locking gear 602, thereby reducing the friction and wear between the locking gears 602 and extending the service life of the equipment. The inlet hole opened at the top of the lubrication box 7 is convenient for adding lubricant to the lubrication box 7 to ensure the normal operation of the lubrication mechanism. The outlet port opened at the bottom of the installation box 5 can discharge the lubricant scattered from the lubrication box 7 in time to avoid the accumulation of lubricant in the installation box 5 and affecting the normal operation of the equipment. The design of this lubrication mechanism effectively reduces the maintenance cost of the equipment and improves the reliability and stability of the equipment.

[0052] A method for using a heart suspension mechanism, comprising:

[0053] Step 1: When the staff performs cardiac surgery on the patient, they first place the two connecting plates 1 in the appropriate position. The multiple first connecting belts 2 connected to the opposite sides of the two connecting plates 1 play a preliminary connection and positioning role. Then, multiple fixing belts 3 and multiple second connecting belts 4 are used to fix the patient's heart area.

[0054] Step 2: When the fixing belt 3 needs to be suspended, the staff pulls the suspension rope 504 extending to the outside of the installation box 5. The suspension rope 504 drives the winding roller 501 to rotate inside the installation box 5. At this time, the torsion spring 503 is deformed to store elastic potential energy.

[0055] Step 3: After the staff adjusts the suspension rope 504 to the appropriate length, they push the limiting magnet 605 so that it attracts the mounting magnetic plate 606 on one side of the limiting chute 603. At this time, the limiting magnet 605 drives the rotating shaft 6 to move, so that the two locking gears 602 are tightly engaged, thereby locking the rotation of the winding roller 501.

[0056] Step 4: When the suspension rope 504 needs to be released, the staff pushes the limiting magnetic block 605, causing it to attract the mounting magnetic plate 606 on the other side of the limiting slide 603 with opposite poles. At this time, the two locking gears 602 are disengaged, and the winding roller 501 automatically rotates under the elastic force generated by the recovery deformation of the torsion spring 503, and the suspension rope 504 is wound back into the mounting box 5;

[0057] Step 5: During the rotation of the locking gear 602 , the lubricating roller 701 rubs against the locking gear 602 , thereby applying the lubricant in the lubrication box 7 to the locking gear 602 to achieve lubrication.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

At this time, the limiting magnet (605) drives the rotating shaft (6) to move, so that the two locking gears (602) are tightly engaged, thereby locking the rotation of the winding roller (501); Step 4: When the suspension rope (504) needs to be released, the staff pushes the limiting magnetic block (605) so that it attracts the mounting magnetic plate (606) on the other side of the limiting slide groove (603) with different poles. At this time, the two locking gears (602) are disengaged, and the winding roller (501) automatically rotates under the elastic force generated by the torsion spring (503) recovering its deformation, and the suspension rope (504) is wound back into the mounting box (5); Step 5: During the rotation of the locking gear (602), the lubricating roller (701) and the locking gear (602) rub against each other, thereby applying the lubricant in the lubrication box (7) to the locking gear (602) to provide lubrication.
