Description

Technical Field

[0001] The invention relates to the field of medical technology, and in particular to an open waterproof motor. Background Art

[0002] A ventricular assist device (VAD) or total artificial heart (TAH) is a mechatronic device that partially or completely replaces the heart's function of pumping blood. It has become an important means of treating end-stage heart failure, and its core component is the blood pump. Artificial hearts in the prior art usually place the blood pump outside the heart, draw blood from the heart, increase the pressure, and then deliver it to the aorta to maintain human blood circulation.

[0029] Rotating motion parts DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0031] On the one hand, the present application discloses an open waterproof motor, which includes a support rod, a driving component, a rotating motion component, and a power cord, characterized in that the support rod is connected to the driving component, the support rod is connected to the rotating motion component, and the driving component is coupled to the rotating motion component, so that when power is turned on, the driving component can drive the rotating motion component to rotate and output kinetic energy, wherein the driving component has an electromagnetic coil, the electromagnetic coil is sealed in the driving component, the rotating motion component has a permanent magnet, the permanent magnet is sealed in the rotating motion component, and the power cord is electrically connected to the electromagnetic coil in a sealed manner.

[0032] In the open waterproof motor of the present application, the driving component is coupled to the rotating motion component with an electric energy to kinetic energy conversion efficiency higher than 70%, and the electric energy to kinetic energy conversion efficiency can also be greater than 75%, greater than 85%, or even greater than 90%.

[0033] Those skilled in the art should understand that by adjusting the various types of losses of the motor, the key factors affecting the various types of losses can be clarified, thereby improving the electric energy to kinetic energy conversion efficiency of the motor. Those skilled in the art know that the electric energy to kinetic energy conversion efficiency of the motor can be improved in the following ways: 1. Reduce the loss when the current flows through the electromagnetic coil winding. 2. Control the core loss. 3. The improvement in efficiency is closely related to material consumption. The prior art already has various commercial components that can enable the combination of electromagnetic coils and permanent magnets to achieve the electric energy to kinetic energy conversion efficiency described above.

[0034] The open waterproof motor described in the present application is durable, uses fluid to dissipate heat, has a high energy conversion rate, has a simple structure, reduces other components such as the housing, and is therefore lightweight, and provides a maximum fluid flow channel. It can be implanted in the body as a whole to pump blood that meets the body's blood supply needs into the aorta and coronary arteries to maintain body blood supply.

[0035] In some embodiments, the open waterproof motor is not provided with a housing. The present application seals the electromagnetic coil and the permanent magnet in the driving component or the rotating motion component, and the power line is electrically connected to the electromagnetic coil in a sealed manner, so that the open waterproof motor will not leak electricity even if the motor is not provided with a housing, further reducing the overall weight and size of the motor, and providing a blood flow channel to the maximum extent to meet the blood supply needs of the human body.

[0036] In some embodiments, the support rod has an upper top, a lower top and a side portion, the side portion is at least partially separated from a line connecting the upper top and the lower top by a certain distance, the two ends of the rotary motion component are respectively connected to the upper top and the lower top, and the driving component is connected to the side portion. The support rod is used to fix the rotary motion component and the driving component at the same time, and also reduces the number of components of the motor as much as possible, making the motor simple in structure, light in weight and durable.

[0037] In some embodiments, the support rod has an upper top, a lower top and a side portion, the side portion is at least partially separated from the line connecting the upper top and the lower top by a certain distance, the first end of the rotating motion component is connected to the lower top, the first end of the driving component is connected to the upper top, and the second end of the rotating motion component is coupled to the second end of the driving component. The coupling connection described in the present application means that the second end of the rotating motion component and the second end of the driving component are arranged in a shape-matched manner, and when power is turned on, the conversion rate of electrical energy to kinetic energy reaches more than 70%, even greater than 75%, greater than 85%, or even greater than 90%. This embodiment is as Figure 3In some embodiments, a protruding axis and a concave hole matching the shape of the axis may be provided at the coupling connection between the second end of the rotational motion component and the second end of the driving component, such a match enables the rotational motion component and the driving component to form a stable match and reduce polarization during rotation.

[0038] In some embodiments, the upper top is provided with an upper top limit device, and the lower top is provided with a lower top limit device, and the two limit devices are used to provide axial limit to the rotational motion component, while allowing the rotational motion component to rotate freely. There is no restriction on the manner of using the limit device to limit the rotational motion component, as long as the purpose of limiting the axial movement of the rotational motion component without limiting the rotational movement of the rotational motion component can be achieved. In some specific embodiments, the limit device has relatively arranged accommodating holes, which are used to provide axial limit to the rotational motion component from both sides, while allowing the rotational motion component to rotate freely.

[0039] In some embodiments, both ends of the rotating motion component are magnetic, which are opposite to the magnetic poles of the corresponding limiting device, so that the rotating motion component is in a suspended state and does not directly contact the limiting device, or at least reduces the contact friction between the rotating motion component and the limiting device.

[0040] Those skilled in the art should understand that the motor may also include a component that performs work externally. In the present application, there is no particular limitation on the component that performs work externally. In some embodiments, the component that performs work externally is a fan blade. Therefore, in some embodiments, the open waterproof motor further includes a fan blade, and the fan blade is connected to the rotating motion component, so that the fan blade is driven to rotate when the rotating motion component rotates.

[0041] In some embodiments, the inclination angle of the fan blades is 12 to 20 degrees, the number of the fan blades can be optionally 2-8, a guide component is arranged above the fan blades, the guide component is directly or indirectly connected to the fan blades and rotates with the fan blades, and the guide component comprises a plurality of guide blades. The guide component is connected to the rotating component, and the guide blades rotate with the fan blades. The guide component plays a guiding role. On the one hand, it can eliminate the vortex of blood, and on the other hand, it can shunt blood into the aorta and coronary artery, which has a better blood supply effect, improves the direction of blood flow, and improves the efficiency of pumping blood. Those skilled in the art can design the specific form of the guide component and the guide blade according to actual needs.

[0042] In some embodiments, the open waterproof motor further includes an anti-oxidation and / or anti-coagulation coating, wherein the anti-oxidation and / or anti-coagulation coating includes one or both of a metal coating and an anticoagulant coating.

[0043] In some embodiments, the operating speed of the rotary motion component is 1000 to 5000 rpm, preferably 2000 to 2500 rpm, and the power is 1 to 6 watts, for example 1.5 to 5 watts, and the area and inclination angle of the fan blades enable a blood flow of 3 to 15 liters / minute, for example 4-6 liters / minute, to be provided at this speed. Estimated with a pump with a power of 1.5 watts and a head of 1 m / s, according to the power and flow formula of the axial flow pump, flow = power / (head × density × acceleration of gravity), the density of blood is about 1050 kg / m3, and the acceleration of gravity is 9.8 m / s2. Substituting the numerical value into the above formula, it can be obtained that: flow = 1 watt / (1 m / s × 1050 kg / m3 × 9.8 m / s2) × 60 × 1000 = 5.83 liters / minute. That is, a smaller power can meet the blood needs of the human body. The inner cavity of the aorta allows for the installation of larger equipment, which can meet the blood supply demand at a lower rotation speed. Preferably, the operating speed of the rotating motion component is 2000 to 2500 rpm. The lower operating speed is less likely to cause hemolysis, thereby improving safety.

[0044] In some embodiments, the radial dimension is 15-33 mm, such as 20-28 mm, and the axial dimension is 25-65 mm, such as 30-50 mm. The radial dimension in this application refers to the dimension of the open waterproof motor in the rotation direction of the rotating moving part, and the axial dimension refers to the dimension of the open waterproof motor perpendicular to the rotation direction of the rotating moving part.

[0045] On the other hand, the present application also discloses an artificial heart, which adopts the open waterproof motor described in any of the above items and a support ring supporting the motor, wherein the support ring has an annular structure and is used to be arranged at the base of the aortic valve ring.

[0046] The "annular structure" in the present application may be a complete ring or a ring larger than a semicircle.

[0047] The aorta is the main conduit for transporting blood to all parts of the body. It has a large size. At the root of the aorta, the arterial wall opposite to the aortic valve bulges outward, forming a larger inner cavity between the valve and the aortic wall. The larger inner cavity provides a space for the implantation of the open waterproof motor or artificial heart of the present application, and after the components of the open waterproof motor or artificial heart occupy part of the blood flow channel and form a blockage to the blood flow, the remaining blood flow channel can still meet the blood supply needs of the whole body. The artificial heart of the present application is arranged at the base of the aortic valve ring through the annular structure of the support ring. The open waterproof motor drives the fan blades to rotate, and the blood in the left ventricle is continuously introduced into the aorta, thereby achieving the effect of replacing the heart's pumping function. The setting of the open waterproof motor of the present application can restore the heart's blood supply pathway under normal physiological conditions to the maximum extent. It can meet the blood supply needs of the whole body and cause no damage to the blood by working at lower energy consumption and lower fan blade speed. It can be placed in the body for a long time to replace the heart's pumping function.

[0048] In some embodiments, the artificial heart further comprises an artificial arterial wall, and the power cord passes through the artificial arterial wall. The artificial arterial described in the present application may be those known in the prior art. The raw materials for manufacturing the artificial blood vessels include nylon, polyester, Teflon and natural mulberry silk, etc. The manufacturing method of the artificial blood vessel includes weaving, and the weaving methods include knitting, braiding and weaving. After being woven into a tubular fabric, it is processed into a spiral artificial blood vessel by post-processing, which can be bent at will without being sucked and deflated. In the present application, the terms "artificial blood vessel" and "artificial arterial blood vessel" have the same meaning and can be used interchangeably. They all refer to blood vessels made by artificial methods, which can replace human arterial blood vessels and are not prone to serious side effects. They are used in direct contact with blood, meet blood compatibility requirements, have both anti-coagulation properties and do not affect the composition and properties of blood, and their strength is large enough that when the wire passes through the artificial blood vessel wall, it will not be damaged in the state of use.

[0049] In some embodiments, the artificial arterial vessel wall is a segment of an artificial arterial vessel.

[0050] In some embodiments, one end of the artificial artery is connected to the support ring.

[0051] The medical device of the present application can be implanted in a human body or an animal body through the Bentall surgery technique. The Bentall surgery described in the present application has the meaning commonly known to those skilled in the art, and its full name is ascending aorta replacement with artificial blood vessels with aortic valve, which uses artificial blood vessels with valves to replace the ascending aortic root and aortic valve, and belongs to the thoracic aortic aneurysm surgery of cardiovascular surgery.

[0052] The manufacturing method and raw materials of the open waterproof motor or artificial heart described in this application are not particularly limited, and can be manufactured using methods and materials known in the prior art, as long as they can meet the specific human use environment. After understanding the structure disclosed in this application, ordinary technicians in this field can select materials and methods known in the prior art to manufacture corresponding products.

[0053] The above ranges can be used alone or in combination. The present application can be more easily understood through the following examples.
