Description

Technical Field

[0001] The utility model relates to the technical field of coronary artery fixation, in particular to a coronary artery fixation sucker structure. Background Art

[0002] During heart surgery, such as coronary bypass surgery, the coronary arteries need to be fixed to prevent the arteries from rupturing, thereby avoiding damage to the heart tissue and protecting the patient's safety.

[0003] A common adsorption method is to set a hole on the U-shaped stent, and connect the hole to an empty plastic bag through a pipe. The plastic bag has a certain amount of air inside, and the plastic bag is also used as a drainage bag to drain excess blood when a blood vessel ruptures. The specific method of fixing and adsorbing the stent to the coronary artery is to squeeze the plastic bag to absorb the plastic bag and achieve the attachment of the stent to the artery.

[0004] This method has the following problems: 1. When the hole is subjected to negative pressure, the deformation is small and the adsorption capacity is low, which makes it difficult to adsorb and easy to fall off; 2. The negative pressure formed by squeezing the blood storage bag is uncontrollable, and the pressure value formed is completely dependent on the volume of the extrudable gas in the blood storage bag on site. A small negative pressure cannot play a fixing role, and a large negative pressure can easily cause deformation; 3. The pressure formed is uncontrollable, and the blood vessel cannot actually form a perfect fit with the stent. Summary of the invention

[0005] In order to solve the above-mentioned problems in the prior art, the utility model provides a coronary artery fixing suction cup structure.

[0006] The technical solution of the utility model: a coronary artery fixing suction cup structure comprises: a fixing frame, wherein the fixing frame comprises: two legs and a connecting seat, wherein the legs and the connecting seat form a U-shaped structure; a negative pressure mechanism is provided on the legs, and the negative pressure mechanism can generate negative pressure suction to adsorb and fix the coronary artery.

[0007] In one of the embodiments, the negative pressure mechanism includes: a negative pressure suction cup, which is arranged on the inner side of the support leg, and a ventilation pipe is provided on the connecting seat, and the ventilation pipe is connected to the negative pressure suction cup through the connecting seat; a pressure regulating valve is provided on the ventilation pipe.

[0008] In one embodiment, the negative pressure suction cup is a double suction cup structure, including: an inner suction cup, an outer suction cup is provided on the outside of the inner suction cup, the outer suction cup completely wraps the inner suction cup therein, and the outer suction cup is made of soft material and droops downward with gravity in a natural state.

[0009] In one of the embodiments, a reinforcing rib is provided on one side of the outer surface of the outer suction cup.

[0010] In one embodiment, the height and thickness of the reinforcing rib are both less than 1 mm.

[0011] In one of the embodiments, a negative pressure tube is provided in the supporting leg, and the negative pressure suction cup is connected to the ventilation tube through the negative pressure tube.

[0012] In one embodiment, the supporting legs are made of transparent soft rubber material, and the negative pressure tube is made of hard material.

[0013] In one of the embodiments, a lighting mechanism is provided on the connection base, and the lighting mechanism includes: a lighting lamp and a power source, and the lighting lamp is connected to a power point.

[0014] In one of the embodiments, the illuminating lamp and the connecting socket are connected together via a shaping tube, and the shaping tube can arbitrarily adjust the lighting direction of the illuminating lamp.

[0015] In one of the embodiments, the negative pressure suction cup protrudes outside the leg.

[0016] The working principle of the utility model is as follows: a fixing frame of a U-shaped structure is placed on both sides of the coronary artery to be fixed, the outer suction cup is very soft and can easily fit with the blood vessel (coronary artery) through tension or gravity when in contact with liquid, at this time, a regulating valve is opened to form negative pressure, and a ventilating tube is used to connect the negative pressure suction cup so that the inner suction cup and the blood vessel are stably adsorbed, thereby achieving the purpose of fixing the coronary artery; when the negative pressure suction cup needs to be removed, it is only necessary to gradually reduce the negative pressure so that the inner suction cup is removed first; when an external force is applied, the reinforcing ribs on the outer suction cup cause the hardness of the outer suction cup to be uneven, so that a gap can be easily opened from one side of the reinforcing ribs, thereby completing the separation of the negative pressure suction cup from the coronary artery.

[0017] The beneficial effects of the utility model are as follows: 1. The negative pressure suction cup with a double suction cup structure has stable adsorption. In the state of no negative pressure, the outer suction cup is very soft and can easily fit with the blood vessel through the tension or gravity when in contact with the liquid, so as to form initial adsorption and improve the stability of adsorption; 2. Through the pressure regulating valve, the size of the negative pressure can be controlled according to the actual situation, and adsorption and detachment are very convenient and highly controllable; 3. It has a lighting mechanism, which can enhance the visualization effect through the lighting lamp, thereby improving the guarantee for the safe operation of related operations.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 4 The coronary artery 1 fixing suction cup structure comprises: a fixing frame, the fixing frame comprises: two legs 2 and a connecting seat 1, the legs 2 and the connecting seat 1 form a U-shaped structure; a negative pressure mechanism is provided on the legs 2, and the negative pressure mechanism can generate negative pressure suction to adsorb and fix the coronary artery 10.

[0026] In this embodiment, the negative pressure mechanism includes: a negative pressure suction cup 3, which is arranged on the inner side of the support leg 2, and a ventilation pipe 5 is provided on the connecting seat 1, and the ventilation pipe 5 is connected with the negative pressure suction cup 3 through the connecting seat 1; a pressure regulating valve 6 is provided on the ventilation pipe 5.

[0027] In this embodiment, the coronary artery 10 is adsorbed by the negative pressure suction cup 3, and the adsorption adhesion between the negative pressure suction cup and the blood vessel is stronger than that between the holes. On the other hand, a layer of anti-blood coagulation filter membrane is also covered on the suction cup to reduce the risk of thrombosis.

[0028] In addition, when adsorbing the artery, the adsorption pressure value needs to be appropriate to avoid rupture of the blood vessel. Therefore, in this embodiment, a pressure regulating valve 6 is also provided, and the pressure regulating valve 6 can achieve fine adjustment of the pressure.

[0029] In this embodiment, the negative pressure suction cup 3 is a double suction cup structure, including: an inner suction cup 302, an outer suction cup 301 is provided on the outside of the inner suction cup 302, and the outer suction cup 301 completely wraps the inner suction cup 302 therein. The outer suction cup 301 is made of soft material and droops downward with gravity in a natural state.

[0030] Specifically, the inner suction cup 302 and the outer suction cup 301 have a connecting tube at the rear, which is indirectly connected to the regulating valve through the connecting tube; when the blood vessel (the blood vessel is the coronary artery 10) is attached to the negative pressure suction cup 3, the outer suction cup 301 first contacts the outer surface of the blood vessel. During the operation, the coronary artery 10 has liquid on its surface, and the liquid has a certain osmotic pressure, also known as tension. Under the tension of the liquid, the outer suction cup adheres to the surface of the blood vessel and forms mutual suction with the blood vessel; although the tension between the outer suction cup 301 and the blood vessel is not enough to fix the blood vessel, it plays a preliminary positioning role, and also forms a small closed space for the inner suction cup 302, effectively improving the adsorption efficiency of the inner suction cup 302; at this time, the regulating valve 6 is opened, and negative pressure adsorption is quickly generated in the closed space formed after the outer suction cup 301 fully adheres to the blood vessel. Through double adsorption, the adsorption reliability of the double suction cup structure is guaranteed to be high; the outer suction cup is made of a soft material and has a large adsorption area, which minimizes the possibility of damage to the blood vessel surface.

[0031] In this embodiment, a reinforcing rib 303 is provided on one side of the outer surface of the outer suction cup 301 .

[0032] Specifically, when the device needs to be separated from the coronary artery 10, the surface hardness of the outer suction cup 301 caused by the reinforcing ribs 303 is uneven, that is, the hardness of the place with the reinforcing ribs 303 is greater than that of the place without the reinforcing ribs 303; thus, when the negative pressure is removed, it is easy to open a gap from the side with the reinforcing ribs 303 by pulling with external force, so that the outer suction cup 301 is easily detached, which greatly improves the separation effect.

[0033] In this embodiment, the height and thickness of the reinforcing rib 303 are both less than 1 mm.

[0034] Specifically, the reinforcing rib 303 is integrally formed with the outer suction cup 301 , and the height and thickness are both less than 1 mm; if the size of the reinforcing rib 303 is too large, the strength and hardness of the reinforcing rib 303 will be too high, and it will not be soft enough, and it will not be able to deform and thus cannot wrap the coronary artery 10 .

[0035] In this embodiment, a negative pressure tube 4 is provided in the supporting leg 2 , and the negative pressure suction cup 3 is connected to the ventilation tube 5 through the negative pressure tube 4 .

[0036] In this embodiment, the supporting legs 2 are made of transparent soft rubber material, and the negative pressure tube 4 is made of hard material.

[0037] Specifically, in the present embodiment, the negative pressure tube 4 is made of metal, and the negative pressure tube 4 has a certain strength to ensure the stability of the U-shaped structure of the fixing frame, and will not be deformed during the negative pressure adsorption process; in addition, the supporting leg 2 is made of transparent soft rubber material, so that the supporting leg 2 will not cause secondary wounds when touching the affected area, thereby protecting human skin tissue and improving contact comfort.

[0038] In this embodiment, a lighting mechanism is provided on the connecting base 1 , and the lighting mechanism includes: a lighting lamp 8 and a power supply 7 , and the lighting lamp 8 is electrically connected to the power supply 7 .

[0039] Specifically, the lighting lamp 8 can clearly observe the situation of the affected part, which is beneficial to the operation and belongs to a safety guarantee device for assisting the operation.

[0040] In this embodiment, the illuminating lamp 8 and the connecting base 1 are connected together via a shaping tube 9 , and the shaping tube 9 can adjust the lighting direction of the illuminating lamp 8 arbitrarily.

[0041] Specifically, in the present embodiment, the lighting lamp 8 is electrically connected to the power supply 7 via the shaping tube 9; during operation, the user can arbitrarily turn the shaping tube 9, which has a shaping function and can move its position. After being turned, the position remains unchanged, thereby controlling the position of the lighting lamp 8 to adapt to various operating environments.

[0042] In this embodiment, the negative pressure suction cup 3 protrudes outside the supporting leg 2.

[0043] Specifically, the negative pressure suction cup 3 protruding outside the leg 2 can ensure that the negative pressure suction cup 3 is in full contact with the coronary artery 10 .

[0044] The working principle of the utility model is as follows: a U-shaped fixing frame is placed on both sides of the coronary artery 10 to be fixed, and the outer suction cup 301 is very soft and can easily fit with the blood vessel (coronary artery) through tension or gravity when in contact with liquid. At this time, the regulating valve is opened to form negative pressure, and the ventilation tube 5 is used to connect the negative pressure suction cup 3, so that the inner suction cup 302 and the blood vessel are stably adsorbed, thereby achieving the purpose of fixing the coronary artery 10; when the negative pressure suction cup 3 needs to be removed, it is only necessary to gradually reduce the negative pressure so that the inner suction cup 302 is removed first; when an external force is applied, the reinforcing ribs 303 on the outer suction cup 301 cause the outer suction cup 301 to have uneven hardness, so that a gap is easily opened from one side of the reinforcing ribs 303, thereby completing the separation of the negative pressure suction cup 3 and the coronary artery 10.
