Background
The heart valve is a checkpoint between different cardiovascular structures, can only be opened and closed in a certain specific direction, ensures that blood can only flow forward, but can not flow backward, and the mitral valve is a one-way valve between the left atrium and the left ventricle, ensures that blood flows directionally from the left atrium to the left ventricle and flows through a certain blood flow, and blood flows from the left atrium to the left ventricle through the mitral valve, is pumped into the main artery from the left ventricle and flows to the whole body. The mitral valve is opened, blood flows into the left ventricle from the left atrium, then the mitral valve is closed, so that when the left ventricle contracts and pumps blood to the aorta, the blood cannot flow back into the left atrium, and if the mitral valve is diseased and cannot be closed sufficiently, the blood flows back into the left atrium when the left ventricle contracts, namely the mitral valve flows back.
Mitral regurgitation is the most common heart valve disorder worldwide, and it causes a decrease in blood flow to various parts of the body, and in order to compensate, the heart will try to pump blood more forcefully, increasing the heart burden. Patients with severe mitral regurgitation can develop various debilitating symptoms such as shortness of breath, palpitations, dizziness, and fatigue. These patients are at risk of poor quality of life, significantly limited activity, repeated hospitalization for heart failure and increased mortality, and chronic severe mitral regurgitation is often accompanied by heart failure, which can result in death if untreated.
At present, in valve repair surgery, the control mode of a device for controlling a wire locking device to lock an anchor is simpler, only the movement and rotation of a tube can be realized, the device cannot provide other assistance or reference for doctor locking operation, and the locking force is mostly determined by virtue of doctor experience during locking, so that the final valve repair effect is poor, the valve shape is irregular, and the subsequent recovery effect is influenced.

Further, fig. 3 and 4 schematically show schematic structural views of a second rotating member according to an embodiment of the present invention from different angles, as shown in fig. 1 to 4:
the second rotary member 3012 includes a second housing 30122, a rotary block 30123, and an elastic member 30124;
The limiting post 30112 is arranged in the rotating block 30123 and the elastic piece 30124, the rotating block 30123 and the elastic piece 30124 are arranged in the second shell 30122, and the second shell 30122 and the rotating block 30123 are circumferentially limited;

Specifically, the first limiting groove 30113 includes a first side wall 30114 and a second side wall 30115, the first side wall 30114 is obliquely disposed, when the rotating block 30123 rotates forward relative to the fixed base 30111, the first limiting block 30121 abuts against the first side wall 30114, so that the rotating block 30123 compresses the elastic member 30124, and when the first limiting block 30121 moves to the next first limiting groove 30113, the elastic member 30124 stretches;
When the doctor controls the second rotating member 3012 to rotate, the first limiting block 30121 moves along the inclined first side wall 30114 to the next first limiting groove 30113, so that the first limiting block 30121 and the rotating block 30123 gradually move upwards, the elastic member 30124 is gradually compressed, and when the first limiting block 30121 moves to the junction of the first side wall 30114 and the next second side wall 30115 and moves further, the first limiting block 30121 is not limited any more, and the elastic member 30124 stretches and resets, so that the first limiting block 30121 pops into the first limiting groove 30113 and impacts the first side wall 30114 and the second side wall 30115, and sounds and is perceived by the doctor, thereby realizing control over locking force.
Further, the second side wall 30115 abuts against the side portion of the first limiting block 30121 to prevent the rotary block 30123 from rotating reversely, when the first limiting block 30121 is located in the first limiting groove 30113 and moves reversely relative to the limiting post 30112, the first limiting block 30121 contacts the second side wall 30115 and is limited by the second side wall 30115, so that reverse rotation of the wire locker spring tube 20 is prevented, and after the wire locker is locked in place, the wire locker is prevented from being loosened due to external reasons such as false contact, so that screwing force cannot be controlled.
Further, the rotating block 30123 and the second housing 30122 are circumferentially limited, which specifically includes:
A second limiting groove 30126 is formed in the side wall of the second shell 30122, and the second limiting groove 30126 penetrates through the second shell 30122;

The axial length of the second limiting groove 30126 is greater than that of the first limiting groove 30113, when the second limiting block 30127 moves axially in a direction away from the first limiting groove 30113, the first limiting block 30121 extends out of the first limiting groove 30113, and the second rotating member 3012 can rotate reversely relative to the fixed base 30111.
Specifically, a second limiting groove 30126 is provided on the side of the second housing 30122, and a second limiting block 30127 is provided on the side of the rotating block 30123, so that the rotating block 30123 and the second housing 30122 are circumferentially limited by passing the second limiting groove 30126 through the second limiting groove 30126, and when a doctor controls the second housing 30122 to move, the rotating block 30123 can move synchronously.
When the doctor controls the second shell 30122 to excessively rotate so that the locking force of the wire locking device is excessively large, in order to avoid that the locking force of the wire locking device cannot be corrected due to the fact that the wire locking device cannot reversely rotate, the axial length of the second limiting groove 30126 is set to be larger than that of the first limiting groove 30113;
In an initial state, the first limiting block 30121 is located in the first limiting groove 30113 and is limited by the second side wall 30115 to move in the reverse direction of the first limiting block 30121, when the forward rotation is excessive, the second limiting block 30127 is controlled to slide in the second limiting groove 30126 to lift the rotating block 30123, so that the first limiting block 30121 moves out of the first limiting groove 30113, and at the moment, the second limiting block 30127 can be controlled to rotate in the reverse direction, so that the rotating block 30123 and the second housing 30122 integrally rotate in the reverse direction, and the excessive locking force is corrected.

Specifically, the diameter of the opening of the locking member 302 is smaller than the diameter of the pattern enclosed by the plurality of clamping members 30128 in the initial state, and the diameter of the opening of the locking member 302 is larger than the diameter of the pattern enclosed by the plurality of clamping members 30128 in the state of clamping the wire locker spring tube 20, so that the plurality of clamping members 30128 can be gradually gathered when the locking member 302 moves axially away from the second housing 30122, and the effect of clamping the wire locker spring tube 20 is achieved.
The locking member 302 is threadably coupled to the top of the second housing 30122 such that rotation of the locking member 302 causes the locking member 302 to move axially relative to the second housing 30122, and the plurality of clamping members 30128 are resilient such that when the locking member 302 no longer clamps the clamping members 30128, the clamping members 30128 can be reset to release the wire locker spring tube 20, allowing the second adjustment structure 303 to control rapid axial movement and circumferential rotation of the wire locker spring tube 20.
