As shown in fig. 1 and fig. 4, a vascular diameter-adjusting device provided by an embodiment of the present invention includes: the transmission rod comprises a shell 100, a transmission rod 200, a first supporting rod 300, a second supporting rod 400 and a limiting rod 500; the transmission rod 200 is slidably inserted into the shell 100, and the middle part of the first support rod 300 is hinged with the middle part of the second support rod 400; one of the housing 100 and the driving rod 200 is hinged with one end of the first supporting rod 300, and the other of the housing 100 and the driving rod 200 is hinged with one end of the second supporting rod 400; one of the other end of the first support bar 300 and the other end of the second support bar 400 is slidably hinged to the stopper bar 500 in the extending direction of the stopper bar 500, and the other of the other end of the first support bar 300 and the other end of the second support bar 400 is hinged to the stopper bar 500.
When the radial dimension of the blood vessel is matched, the control transmission rod 200 slides relative to the shell 100, so that the first support rod 300 and the second support rod 400 can be driven to adjust the distance between the shell 100 and the limit rod 500 in a shearing mode, and when the shell 100 and the limit rod 500 are supported in the blood vessel together, the radial dimension of the blood vessel can be adjusted, so that the vascular fracture of a patient can be matched with an artificial blood vessel.

In addition, even if the diameter of the vascular fracture deviates from the diameter of the artificial blood vessel, the vascular diameter regulating device can eliminate the deviation, thereby achieving the optimal suturing effect.
In addition, the blood vessel diameter-adjusting device can be used for measuring the size of a blood vessel fracture, so that a corresponding artificial blood vessel can be selected, and the phenomenon that the size deviation is generated when the artificial blood vessel is selected only through image detection is avoided.

When the first handle 700 and the second handle 800 are gripped and the included angle between them is reduced, the second handle 800 drives the transmission rod 200 to slide distally relative to the shell 100, and the first support rod 300 and the second support rod 400 swing and drive the shell 100 and the spacing rod 500 to increase, so as to increase the radial dimension of the vascular fracture supported by the grid support 600.
Further, an elastic member 900 is connected between the first handle 700 and the second handle 800, the elastic member 900 may be configured as a spring, a torsion spring or a shrapnel, and the elastic member 900 has a tendency to drive the first handle 700 to swing relative to the second handle 800 and reduce the radial dimension of the vascular fracture supported by the grid support 600.
As shown in fig. 1, 3 and 4, the housing 100 is provided with a third sliding groove 106 extending in the sliding direction of the transmission rod 200; the second handle 800 is hinged with the transmission rod 200 through the fifth hinge shaft 801, and the fifth hinge shaft 801 is slidably fitted in the third slide groove 106, thereby improving structural compactness, and the third slide groove 106 can guide the sliding of the fifth hinge shaft 801.
