the delivery catheter comprises a first delivery catheter, a central control unit, and a second delivery catheter; the distal parts of both the first delivery catheter and the second delivery catheter are equipped with releasable connection mechanisms that match the detachable connection mechanisms. ## Claims ### Claim 1 A component of an integrally detachable valve clamp and delivery system thereof, comprising: a control handle; a delivery catheter connected to the control handle; and a valve clamp connected to the delivery catheter; wherein the valve clamp is equipped with an inner catheter and an outer catheter, both of which are equipped with detachable connection mechanisms; the delivery catheter comprises a first delivery catheter, a central control unit, and a second delivery catheter; the distal parts of both the first delivery catheter and the second delivery catheter are equipped with releasable connection mechanisms that match the detachable connection mechanisms; when pre-installed, the detachable connection mechanism on the inner catheter is connected to the releasable connection mechanism on the first delivery catheter through the central control unit, forming a first disassembly part, while the detachable connection mechanism on the outer catheter is connected to the releasable connection mechanism on the second delivery catheter through the central control unit, forming a second disassembly part; when the central control unit is moved away from the first disassembly part and the second disassembly part, the first delivery catheter separates from the inner catheter, and the second delivery catheter separates from the outer catheter. ### Claim 2 (depends on 1) The component of an integrally detachable valve clamp and delivery system thereof according to claim 1, wherein the relative position of the central control unit and the inner catheter remains unchanged when the first disassembly part and the second disassembly part undergo relative displacement. ### Claim 3 (depends on 1) The component of an integrally detachable valve clamp and delivery system thereof according to claim 1, wherein on the axial section of the delivery catheter, the first disassembly part and the second disassembly part are in the same or different positions, and when the central control unit is moved away from the first and second disassembly parts respectively/simultaneously, the first delivery catheter and the inner catheter, the second delivery catheter and the outer catheter are correspondingly released and separated in sequence/simultaneously. ### Claim 4 (depends on 1) The component of an integrally detachable valve clamp and delivery system thereof according to claim 1, wherein the valve clamp further comprises a connector, a first clamping arm, a second clamping arm, a first linkage rod, and a second linkage rod; the first clamping arm and the second clamping arm are hinged with the connector and are arranged on the left and right sides of the outer catheter; the connector is connected to the inner catheter; one end of the first linkage rod is connected to the first clamping arm, while the other end of the first linkage rod is connected to the outer catheter; and one end of the second linkage rod is connected to the second clamping arm, while the other end of the second linkage rod is connected to the outer catheter. ### Claim 5 (depends on 1) The component of an integrally detachable valve clamp and delivery system thereof according to claim 1, wherein the central control unit restricts the relative radial displacement between the detachable connection mechanisms and the releasable connection mechanisms to prevent the detachable connection mechanisms from detaching from the releasable connection mechanisms. ### Claim 6 (depends on 1) The component of an integrally detachable valve clamp and delivery system thereof according to claim 1, wherein each of the detachable connection mechanisms comprises a first connection section, a second connection section, and an inclined section, and the inclined section is set between the first connection section and the second connection section. ### Claim 7 (depends on 6) The component of an integrally detachable valve clamp and delivery system thereof according to claim 6, wherein the central control unit is a tube, the wall thickness of which is greater than or equal to half of the radial distance between the first connection section and the second connection section on the detachable connection mechanism of the inner catheter. ### Claim 8 (depends on 1) The component of an integrally detachable valve clamp and delivery system thereof according to claim 1, wherein when the releasable connection mechanisms are connected to the detachable connection mechanisms through the central control unit, the first delivery catheter and the second delivery catheter can respectively transmit torque and push force to the inner catheter and the outer catheter. ### Claim 9 (depends on 4) The component of an integrally detachable valve clamp and delivery system thereof according to claim 4, wherein the inner catheter comprises a self-locking rod and a locking head connected to the connector; the first clamping arm and the second clamping arm respectively comprises a long arm and a short arm, and one end of the short arm is provided with a locking part; when the inner catheter is axially moved to enlarge the angle between the long arm of the first clamping arm and the long arm of the second clamping arm to an open state, the locking part on the first clamping arm and the locking part on the second clamping arm are in a staggered fit state; when the inner catheter is moved axially to reduce the angle between the long arm of the first clamping arm and the long arm of the second clamping arm to a closed state, the self-locking rod is moved to achieve matching and locking between the locking head and the locking part. ### Claim 10 (depends on 9) The component of an integrally detachable valve clamp and delivery system thereof according to claim 9, wherein the locking head is a bracket shaped self-expanding structure, which cooperates with the locking part to achieve locking.
