Description

Technical Field

[0001] The present invention relates to the technical field of cardiac surgical instruments, and particularly relates to a suction device applied to coronary artery bypass grafting surgery. Background Art

[0002] Off-pump coronary artery bypass grafting (OPCABG) is an important method for treating severe coronary heart disease. The heart stabilizer can reduce the movement amplitude of the myocardium around the coronary artery-bridge vessel anastomosis site, reduce the difficulty of vascular anastomosis, and is an essential surgical consumable in OPCABG surgery. In the conventional beating-heart coronary artery bypass grafting surgery, the heart stabilizer is fixed on the sternal retractor. The surgeon incises the sternum along the midline of the patient's chest, exposes the thoracic cavity, exposes the heart, and performs cardiac surgery.

[0003] However, the heart stabilizer itself cannot handle the bleeding problem at the anastomosis site during the operation. It is necessary for an assistant to hold a blowing tube or syringe to flush the bleeding at the anastomosis site. Moreover, due to the obstruction of the surgeon, the anastomosis area may not be fully exposed, which affects the surgical operation, increases the surgical difficulty, prolongs the operation time, and causes a waste of human resources. In addition, if the method of flushing the anastomosis site is adopted, the liquid in the pericardial cavity will increase, and an additional adsorption device is needed to adsorb the liquid in the pericardial cavity, which increases the workload of medical staff. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects that the method of flushing the anastomosis site to expose the anastomosis area in the prior art will increase the surgical difficulty, cause a waste of human resources, and increase the workload of medical staff, so as to provide a suction device applied to coronary artery bypass grafting surgery.

[0015] A connecting main pipe, one end of which is communicated with a negative pressure suction device, and the other end is bifurcated into a first fixed pipe and a second fixed pipe respectively fixed to the fixed base;

[0016] A first telescopic pipe, which can be telescoped and folded inside the fixed base and extend out of the fixed base movably; one end of the first telescopic pipe is communicated with the first fixed pipe, and the other end of the first telescopic pipe is communicated with the first universal shaping pipe;

[0017] A second telescopic pipe, which can be telescoped and folded inside the fixed base and extend out of the fixed base movably; one end of the second telescopic pipe is communicated with the second fixed pipe, and the other end of the second telescopic pipe is communicated with the second universal shaping pipe.

[0033] The technical solution of the present invention will be described clearly and completely below 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 creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] As Figures 1 to 4 shown in the specific embodiment of the suction device applied to coronary artery bypass grafting surgery, it includes a fixed base 2, a suction tube 1, a first universal shaping tube 5, and a push-type suction head 3.

[0038] Among them, the fixed base 2 is positioned on a bypass heart fixator or a sternal retractor, and the bypass heart fixator and the sternal retractor are existing conventional devices. The distal end of the suction tube 1 is connected and fixed to the fixed base 2 in communication with a negative pressure suction device. The first universal shaping tube 5 is a rotatable gooseneck tube or a coiled tube, and the angle of the push-type suction head 3 can be adjusted arbitrarily. The first universal shaping tube 5 is in communication with the suction tube 1 and can be adjusted and positioned in any orientation. The inside of the push-type suction head 3 is in a cavity shape and is in communication with the suction tube 1 through the first universal shaping tube 5, and a plurality of first liquid suction holes 31 communicating with the inside of the push-type suction head are provided on the side.

[0039] For the above suction device applied to coronary artery bypass grafting surgery, the position of the push-type suction head 3 is adjusted through the first universal shaping tube 5, so that the push-type suction head 3 is pressed on the anastomosis of the coronary artery bypass graft vessel. And the first universal shaping tube 5 has a certain support strength. Furthermore, when the push-type suction head 3 is pressed on the anastomosis of the coronary artery bypass graft vessel, the movement amplitude of the myocardium around the anastomosis of the coronary artery bypass graft vessel can be reduced, and the difficulty of blood vessel anastomosis can be reduced. During the operation, the negative pressure suction device operates. The first liquid suction holes 31 in this embodiment can adsorb the blood at the anastomosis of the coronary artery bypass graft vessel, and the adsorbed blood can directly enter the negative pressure suction device through the first universal shaping tube and the suction tube 1 to completely expose the area of the anastomosis of the coronary artery bypass graft vessel and ensure the normal operation of the surgery.

[0040] Among them, the anastomosis is the junction point connecting two tissues in a surgical operation. The negative pressure suction device is an existing conventional device, and no detailed description is given here.

[0041] As an alternative embodiment, the negative pressure suction device may also be a surgical suction device, ensuring that the present invention can be applied to most surgical scenarios.

[0042] As a further improved embodiment, the pressing suction head 3 is set to be U-shaped or annular, and can be set according to actual usage requirements. As Figure 1 and Figure 2 shown, the pressing suction head 3 is set to be U-shaped; as Figure 3 and Figure 4 shown, the pressing suction head 3 is set to be annular. The inner cavity of the pressing suction head 3 is set to be hollow.

[0043] As a further improved embodiment, the first liquid suction hole 31 is opened on the inner ring side wall and / or the outer ring side wall of the pressing suction head 3. That is, the first liquid suction hole 31 in this embodiment can be opened at a lower position on the inner ring side wall of the U-shaped pressing suction head, or can be opened on the outer ring side wall of the U-shaped pressing suction head, or can be opened on both the inner ring side wall and the outer ring side wall of the U-shaped pressing suction head. Or the first liquid suction hole 31 can be opened on the inner ring side wall of the annular pressing suction head, or can be opened on the outer ring side wall of the annular pressing suction head, or can be opened on both the inner ring side wall and the outer ring side wall of the annular pressing suction head.

[0044] As a further improved embodiment, a second universal shaping tube 6 capable of adjusting and positioning in any direction is also branched and communicated on the suction tube 1. The second universal shaping tube 6 is a gooseneck tube or a snake tube, and can fix the liquid suction type suction head 4 at any position. The end of the second universal shaping tube 6 is communicated with a liquid suction type suction head 4 capable of adsorbing the blood in the pericardial cavity. When there is too much bleeding at the coronary artery bypass anastomosis, the speed of adsorbing blood only by setting the pressing suction head 3 is relatively slow, and the excess blood will continuously flow into the pericardial cavity. Therefore, in this embodiment, the second universal shaping tube 6 and the liquid suction type suction head 4 are provided. The liquid suction type suction head 4 can be adjusted in any direction, and the excess blood in the pericardial cavity can be adsorbed through the liquid suction type suction head 4, increasing the amount of blood adsorption on the basis of using the pressing suction head, thereby exposing the surgical field of view and facilitating the doctor's next operation. When the adsorption of the excess blood in the pericardial cavity is completed, the liquid suction type suction head 4 can be removed by adjusting the second universal shaping tube 6.

[0045] As a further improved embodiment, the suction device pipeline 1 includes a connecting main pipe 15, a first fixed pipeline 11, a second fixed pipeline 13, a first telescopic pipeline 12 and a second telescopic pipeline 14. One end of the connecting main pipe 15 is connected to the negative pressure suction device, and the other end is bifurcated into the first fixed pipeline 11 and the second fixed pipeline 13 respectively fixed to the fixed base 2. The fixed base 2 in this embodiment has a accommodating cavity. The first telescopic pipeline 12 can be telescopically folded inside the fixed base 2 and can be movably extended from the fixed base 2. One end of the first telescopic pipeline 12 is connected to the first fixed pipeline 11, and the other end of the first telescopic pipeline 12 is connected to the first universal shaping tube 5. The second telescopic pipeline 14 can be telescopically folded inside the fixed base 2 and can be movably extended from the fixed base 2; one end of the second telescopic pipeline 14 is connected to the second fixed pipeline 13, and the other end of the second telescopic pipeline 14 is connected to the second universal shaping tube 6. This embodiment realizes the extension and retraction of the first universal shaping tube 5 and the pressing type suction head 3 through the first telescopic pipeline 12, and realizes the second telescopic pipeline 14 and the liquid suction type suction head 4 through the second telescopic pipeline 14, thereby being able to better meet the needs of actual use.

[0046] As a further improved implementation, switches are respectively provided on the first fixed pipeline 11 and the second fixed pipeline 13, that is, the first fixed pipeline 11 is provided with a first switch 7, and the second fixed pipeline 13 is provided with a second switch 8. The overall working state of the device is controlled by respectively providing switches on the two pipelines. When the first switch 7 is turned on and the negative pressure suction device is in operation, the blood at the anastomosis of the coronary artery bridge vessel can be adsorbed by the press-type suction head 3. When the second switch 8 is turned on and the negative pressure suction device is in operation, the blood in the pericardial cavity can be adsorbed by the suction-type suction head 4. When the first switch 7 and the second switch 8 are turned on at the same time, and the negative pressure suction device is in operation, the synchronous operation function of the press-type suction head 3 and the suction-type suction head 4 is realized.

[0047] The first switch 7 and the second switch 8 can be water-stop buckles or infusion switches.

[0048] As a further improved embodiment, the suction head 4 is configured to be cylindrical or truncated cone-shaped, the interior of the suction head 4 is configured to be cavity-shaped, and the distal end of the suction head 4 is provided with a plurality of second suction holes 41 connected to the interior of the suction head.

[0049] The end of the suction type aspirator head 4 is provided with a protrusion or a groove, and the second suction hole 41 is provided on the outer side wall of the protrusion or on the inner side wall of the groove. The second suction hole 41 is provided at the side, which is more convenient for adsorbing blood. In this embodiment, four second suction holes 41 are provided.

[0050] As an alternative embodiment, the end of the suction type aspirator head 4 is configured as a multi-slot type, and the second suction hole 41 is disposed on the side wall of the slot.

[0051] As a further improved implementation, the bottom end of the fixing base 2 is provided with a fixing buckle 21 fixed to the bypass heart fixator or the sternal retractor. In this embodiment, the positioning of the device can be achieved through the fixing buckle 21. When the bottom end of the fixing base 2 is set on the bypass heart fixator, it is specifically fixedly connected to the movable arm of the bypass heart fixator.

[0052] The specific use process of the present invention is:

[0053] The device is fixed on a bypass heart fixator or a sternal retractor, and the position of the pressing suction device head 3 is adjusted through the first universal shaping tube 5 so that the pressing suction device head 3 is pressed to the anastomosis of the coronary artery graft vessel.

[0054] During the operation, the first switch 7 is turned on and the negative pressure suction device is started, so that the push-type suction head 3 is in a continuous negative pressure adsorption state, thereby continuously adsorbing the blood at the coronary artery graft anastomosis to ensure the normal progress of the operation.

[0055] When the pressure-type suction head 3 absorbs blood but the coronary artery graft anastomosis is still blocked by blood, the second switch 8 can be turned on and the suction-type suction head 4 can be used to absorb the blood in the pericardial cavity to expose the surgical field of view.

[0056] Furthermore, during the operation, the first switch 7 and the second switch 8 can be directly turned on at the same time, so that the pressure-type suction head 3 and the suction-type suction head 4 can absorb the blood at the same time.

[0057] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
