The femoral artery is a common part of CPB peripheral tube for minimally invasive heart surgery, secondary surgery and thoracic aortic surgery, the external circulation surgery is performed through the femoral artery intubator, arterial blood is infused into various organs through the femoral artery intubator, blood flows to the proximal end, in order to maintain enough blood flow, the diameter of the femoral artery intubator needs to be approximate to the internal diameter of the femoral artery of a patient, so that most of blood flows to the proximal end directly through the intubator, and only a small amount of blood flows into the distal end through a gap between the femoral artery intubator and the femoral artery, so that the distal end is in an ischemic state, and if the operation time is too long, the ischemia of the lower limb is obviously changed, and permanent dysfunction can be caused.
For example, when ECMO (extracorporeal membranous pulmonary oxygenation: is mainly used for providing continuous extracorporeal respiration and circulation for patients suffering from severe cardiopulmonary failure so as to maintain the life of the patients), the arterial infusion tube is a femoral artery cannula, and because the treatment time is often long, two places of the femoral artery cannula are usually required to supply blood to the proximal end and the distal end of the lower limb respectively at present, and two puncture points are required, so that the risk of complications such as intimal injury, stenosis of the long-term arterial puncture point, pseudoaneurysm and the like is increased, and the two places of cannula are complex in operation and longer in time, which is more unfavorable for rapid development of treatment.
Disclosure of Invention
The utility model aims to provide a femoral artery integrated perfusion cannula so as to solve the problems that the risk of complications such as possible vascular intima injury, stenosis of a long-term arterial puncture point, false aneurysm and the like caused by two places of the cannula required by blood supply of a proximal end and a distal end in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the femoral artery integrated perfusion cannula comprises a cannula body, wherein the cannula body comprises an insertion end and a connection end, the cannula body is provided with a lumen, the lumen is provided with a sealing plug, and the sealing plug is fixedly connected with a push rod; a plurality of side holes are arranged on one side of the insertion end and the lumen close to the femoral artery and between the cannula body and the lumen.
The working principle and the beneficial effects of the utility model are as follows: according to the scheme, the lumen is increased on the basis of the cannula, the lumen and the cannula form an integrated tube body, the cannula and the lumen are inserted into the femoral artery together during use, the connecting end is externally connected with blood circulation equipment, and at the moment, the sealing plug and a part of the push rod are also inserted into the femoral artery.
Most blood in the femoral artery flows into blood circulation equipment through the connecting end and the cannula body to supply blood to the proximal end, and as the inserting end, one side of the lumen close to the femoral artery and a plurality of side holes are formed between the cannula body and the lumen, blood in the cannula body flows into the femoral artery through the side holes or flows into the lumen respectively, the sealing plug arranged in the lumen blocks the lumen, the push rod pulls the sealing plug to move in the lumen, the length of the lumen is blocked by the sealing plug, so that blood flowing into the lumen can only flow into the femoral artery through the side holes on the lumen, and the blood and the rest of the femoral artery flow into the distal end through gaps between the lumen and the femoral artery after being converged to supply blood.
According to the scheme, through the arrangement of the lumen and the side holes, the blood supply amount of the femoral artery to the distal end is increased, the ischemia state of the distal end is improved, the blood supply of the proximal end and the distal end can be realized by only one cannula, only one puncture point is needed, and two cannulas and two puncture points are needed in the prior art, so that the risk of complications such as vascular intima injury, stenosis of the long-term arterial puncture point, pseudoaneurysm and the like is reduced, and the operation of one cannula is simple and the time is shorter, thereby being beneficial to rapid development and treatment.
Further, the side holes are uniformly spaced along the circumferential direction. The plurality of side holes arranged at intervals in the circumferential direction enable blood to flow into the femoral artery more uniformly and rapidly.
Further, the insertion end is sleeved with a tube core. The die acts as a hermetic insert.
Further, the pore size of the side hole is 2-3 mm. The aperture size can meet the requirement of blood supply at the distal end without influencing blood supply at the proximal end.
Further, the lumen is provided with a buckle for fixing the push rod. The push rod is fixed through the buckle.
Further, the push rod is fixedly connected with a guide ring. The guide ring is convenient to push and pull the push rod.
Further, the push rod is specifically a guide wire. The guide wire is a medical product name, the main material of the guide wire is stainless steel, the surface of the guide wire is polytetrafluoroethylene coating, and the guide wire is used for percutaneous catheter catheterization in the application range.
