As shown in fig. 1, 2, 3, 4 and 5, the non-invasive valve fixing apparatus includes: the fixing body 1 mainly has a fixing function on the valve. In order to meet different use purposes of the fixing body 1, the lower bottom surface of the fixing body 1 may be in a single valve shape (mainly used for single valve operation treatment), may also be in a whole tricuspid valve shape (for tricuspid valve operation treatment), and may of course also be in a whole mitral valve shape (for mitral valve operation treatment).

In order to avoid damage to the valve and realize the fixing effect on the valve, the middle part of the fixing body 1 is provided with an adsorption cavity 2), and the adsorption cavity 2 is connected with an adsorption device (the adsorption device can be an air suction device with controllable suction force in the prior art, so long as the requirement on controllable suction force is met, and the adsorption device is connected with the adsorption cavity 2 through an auxiliary part).

An adsorption hole 3 is communicated between the lower bottom surface of the fixed body 1 and the adsorption cavity 2.

Because the size of fixed body 1 is a lot bigger than absorption chamber 2, so the degree of inclination of absorption hole 3 is very big for it is great to be close to the slope of bottom surface one end under fixed body 1 at absorption hole 3, because absorption hole 3 size is less, bottom surface department size is great under fixed body 1, can have stable adsorption affinity. But because the inclination is big, the valve of absorption blocks up 3 tip in the absorption very easily, avoids adsorbing too big, causes the damage to the valve.

In order to realize the measurement and comparison of the fixed body and use, and in the operation process, the fixed and limiting effects of each operation line are convenient, a plurality of notches 11 are formed in the edge of the fixed body 1.

In order to ensure the adsorption effect of the adsorption holes 3, the cross section of the adsorption holes 3 is trumpet-shaped. The adsorption hole 3 includes: an adsorption tail port 31 at one end inside the adsorption cavity 2 and an adsorption front port 32 at the lower bottom surface of the fixed body 1, and the size of each adsorption hole 3 is gradually reduced from the adsorption front port 32 to the adsorption tail port 31.

In order to ensure that the end parts of the adsorption front openings 31 have the same adsorption force, the adsorption balance of the valve is ensured. From the edge of the fixed body 1 to the adsorption hole 3 below the adsorption cavity 2, the size of the adsorption tail opening 31 of the adsorption hole 3 is gradually reduced.

Preferably, the size of the adsorption tail 31 of the adsorption hole 3 decreases exponentially by 2 from the edge of the fixing body 1 to the adsorption hole 3 below the adsorption chamber 2. Namely: the size of the outermost adsorption tail 31 is 2 times that of the next outer adsorption tail 31, the size of the next outer adsorption tail 31 is 2 times that of the next outer adsorption tail 31, and so on.

In order to be connected with the adsorption device conveniently, the fixing body 1 can be controlled and used conveniently. The upper side of the adsorption cavity 2 is fixedly connected with an auxiliary connecting piece 4. The two sides of the auxiliary connecting piece 4 are adapted to be connected with the fixed body 1 and the adsorption device, so that the fixed body 1 is conveniently connected with other equipment.

In order to facilitate connection with other equipment or equipment, the lower side of the auxiliary connecting piece 4 is adapted to (fixedly connected with) the upper surface structure of the fixing body 1. Preferably, a plurality of connecting protrusions 12 are integrally formed on the upper surface of the fixing body 1, and the connecting protrusions 12 extend into the lower surface of the auxiliary connecting piece 4 to ensure the connecting strength. The upper side of the auxiliary connecting piece 4 is cylindrical, and the outer wall of the cylinder 42 is provided with external threads (convenient connection). The center of the auxiliary connecting piece 4 is a cavity, and the cavity 41 is communicated with the adsorption cavity 2. The adsorption effect of the adsorption device on the valve through the adsorption cavity 2 is conveniently realized.

Of course, the diameter of the cavity 41 is the same as the size of the upper port of the adsorption chamber 2 in order for the adsorption apparatus or the adsorption equipment to smoothly enter the adsorption chamber 2.

In order to further facilitate the connection with the adsorption device, the requirement on the adsorption device is reduced, and the adsorption device in the prior art can meet the use requirement. The fixing device further comprises: the adsorption tube 5 which is conveniently connected with the adsorption device or directly is a component of the adsorption device and the pressing piece 6 which ensures the sealing connection between the adsorption tube 5 and the auxiliary connecting piece 4. Compressing tightly 6 and being connected with adsorption tube 5, adsorption tube 5 passes cavity 41 and stretches into and adsorbs chamber 2, compresses tightly 6 and is connected with adsorption tube 5, compresses tightly 6 downside and is connected with the screw-thread fit of cylinder 42 outer wall, makes adsorption tube 5 and adsorption chamber (2) fixed sealing connection.

Of course, in order to be connected with the thread of the outer wall of the cylinder 42 in a matching manner, a thread cavity 61 is arranged below the pressing piece 6, an inner thread is arranged on the inner wall of the thread cavity 61, and the inner thread is connected with the outer thread of the outer wall of the cylinder 42 in a matching manner. The center of the pressing piece 6 is provided with a connecting hole 62, and the adsorption pipe 5 passes through the connecting hole 62.

In order to achieve a sealing connection of the pressure element 6 and also of the suction tube 5. This connecting hole 62 is close to a tip of screw thread chamber 61 and has been seted up sealed chamber 63 (sealed chamber 63 size is less than screw thread chamber 61 size), at 5 outer wall fixedly connected with sealed clamping ring 7 of adsorption tube, sealed clamping ring 7 size suits with sealed chamber 63 size, and the thickness of sealed clamping ring 7 is less than sealed chamber 63 degree of depth, and inside sealed clamping ring 7 stretched into sealed chamber 63, was equipped with sealing washer 8 between sealed clamping ring 7 and cavity 41 upper end. So that the entire adsorption chamber 2 is isolated from the outside by the seal ring 8.
