Embodiment 1

[0040] A vascular clip, such as figure 1 shown, including:

[0041] Base 10, the base 10 is provided with

[0042] A lock hole 110, the lock hole 110 is cylindrical, and the lock hole 110 connects the upper and lower surfaces of the base 10;

[0043] Pull rod groove 130, the pull rod groove 130 is parallel to the lock hole 110, the opening of the pull rod groove 130 is set on the lower surface of the base 10, the bottom of the pull rod groove 130 is set on the in base 10; and

[0044] Push rod movable cavity 160, the push rod movable cavity 160 is arranged between the lock hole 110 and the pull rod groove 130, the side of the push rod movable cavity 160 adjacent to the lock hole 110 is provided with a communication The push rod movable cavity 160 and the collet opening 120 of the lock hole 110, the side of the push rod movable cavity 160 adjacent to the pull rod groove is provided with a The limiting groove 140 and the positioning hole 150 of the groove;

[0045] clamping...

Embodiment 2

[0057] The difference between the blood vessel clip provided in this example and the blood vessel clip in Example 1 is that the end of the lock hole 110 located on the upper surface of the base 10 is provided with a bell mouth that facilitates the insertion of the clamp arm 30 , and the bell mouth It is convenient for the clip arm 30 to pass through the lock hole 110, such as figure 2 shown.

Embodiment 3

[0059] This example provides the clamping method of the vascular clip, specifically:

[0060] When the blood vessel needs to be closed, the base 10 is placed under the blood vessel to be closed, the clamp arm 30 bypasses the blood vessel, and penetrates through the locking hole 110 on the upper surface of the base 10. After penetrating, the clamp The arm 30 and the upper surface of the base 10 form a binding ring around the blood vessel. The size of the binding ring changes with the movement of the clamp arm 30 to close or release the blood vessel. After the clamp arm 30 passes through the lock hole 110, it is released from the lock The hole 110 is located on the lower surface of the base 10 and passes through the hook 230. After the clamp arm 30 is further tightened by the operator, the crotch 230 moves towards the operator under the drive of the clamp arm 30, and the pull rod 210 moves toward the operator at the same time, and at the same time, the push rod 240 is driven by ...

Abstract

The invention provides a vascular clamp, comprising a base, a clamping arm and a clamping mechanism, wherein a locking hole, a pull rod passage and a sector groove, and the clamping mechanism is located in the base and comprises a pull rod, a clamping head and a clamping hook. According to the vascular clamp, the problem of inconvenient operation when a blood vessel is closed in the prior art is solved, the vascular clamp is ingenious in structure design and small in size, the perivascular tissue cannot be damaged, and blood vessel opening and closing operations are simple, thereby facilitating application by a surgeon. The clamping arm is a round silicone tube with good tensile performance without damaging the blood vessel, is not easy to be damaged in the using process, and has high safety performance. An elastic piece is disposed on the clamping arm to facilitating locking the blood vessel and preventing the clamping arm from sliding, thereby increasing the stability of the vascularclamp.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a blood vessel clamp and a clamping method thereof. Background technique [0002] During the operation, when it is found that the lesion needs surgical resection, in order to ensure the stable implementation of the operation process, the corresponding blood vessel needs to be temporarily closed. Relevant researchers have also developed a vascular clip for closing the blood vessel. [0003] For example: CN105054989B discloses a disposable blood vessel clamp, including a first clamp arm and a second clamp arm, the inner end of the first clamp arm is elastically connected to the inner end of the second clamp arm, and the outer end of the first clamp arm is provided with The hook and the outer end of the second clamping arm are provided with a card seat that cooperates with the clamping hook. This invention has good stability after clamping the blood vessel an...
