Description

Technical Field

[0001] The utility model relates to the technical field of vascular clamps, and more particularly to a vascular clamp capable of clamping and relaxing the vascular clamp at a fixed time. Background Art

[0002] Ischemic preconditioning is an important intervention used to reduce organ damage caused by ischemia and reperfusion. In relevant clinical studies, accurate timing is crucial to achieving the effect of ischemic preconditioning. However, in actual practice, due to the lack of full-time personnel to perform timing, others often do the timing on their behalf, which may lead to timely delays and inaccuracies. In addition, the timekeeper is not always available at all times, and the LCD screen timer on the wall sometimes malfunctions, further affecting the accuracy of time recording. Therefore, there is an urgent need to develop a vascular clamp that can automatically time to ensure the accuracy and reliability of timing during ischemic preconditioning, thereby improving the quality and reproducibility of clinical research. Utility Model Content

[0003] The purpose of this utility model is to provide a timed clamp for clamping loose blood vessels to solve the problems raised in the above background technology:

[0004] Timing and recording of ischemic preconditioning are not precise and reliable enough.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] Preferably, the internal thread of the first clamping rod is connected to a threaded rod, and a groove is provided on the inner side of the second clamping rod close to the threaded rod. The groove is used in conjunction with the threaded rod, and the threaded rod is located on the inner side of the groove. A knob is provided at one end of the threaded rod. The user can tighten the threaded rod to the second clamping rod, thereby locking the second clamping rod to prevent the first clamping rod and the second clamping rod from automatically separating.

[0008] Preferably, the first clamping rod and the outside of the clamp are fixedly connected with teeth, which help the clamp to cooperate with the first clamping rod to clamp the blood vessel more tightly and not easily loosen, so that the clamp can cooperate with the first clamping rod to clamp the blood vessel more firmly.

[0009] Preferably, an anti-slip groove is provided on the inner side of the pinching piece away from the first spring. The anti-slip groove helps to increase the friction between the user's hand and the pinching piece, prevents the pinching piece from slipping out of the hand, and facilitates the user's operation.

[0010] Preferably, the first fixed plate, the second fixed plate and the movable plate are all arc-shaped structures, and the first clamping rod and the second clamping rod are connected by a rotating shaft. Under the action of the rotating shaft, the first clamping rod and the second clamping rod can rotate relative to each other, and the center of the first fixed plate, the second fixed plate and the movable plate coincides with the center of the rotating shaft, so that the first clamping rod and the second clamping rod will not get stuck when rotating relative to each other.

[0011] Preferably, the outer wall of the second fixing plate fits with the inner wall of the first fixing plate, and the second fixing plate fits tightly with the first fixing plate. On the one hand, it can prevent foreign matter from entering the first fixing plate, and on the other hand, it can limit the position between the first clamping rod and the second clamping rod, so that the first clamping rod and the second clamping rod will not swing or misalign when they rotate relative to each other.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1) When using this timed clamp for clamping a loose blood vessel, the user pinches the pinching piece to drive the first clamping rod and the second clamping rod to rotate relative to each other, so that the clamp head on the second clamping rod moves away from the first clamping rod. At the same time, the pinching piece compresses the first spring. After releasing the pinching piece, the elastic force of the first spring drives the clamp head and the first clamping rod to clamp the blood vessel. At this time, the first contact and the second contact are pressed tightly, the timer starts to count, and the buzzer sounds an alarm after the timing ends, thereby achieving the purpose of automatic timing. It is easy to use, simple to operate, and highly practical.

[0014] 2) When using this timed clamp for clamping loose blood vessels, a threaded rod is provided on the first clamping rod, and the threaded rod is located inside the groove on the second clamping rod. The user can tighten the threaded rod against the second clamping rod to lock the second clamping rod, ensuring that the blood vessel is clamped and will not loosen.

The top of the first clamping rod 1 is fixedly connected to a first fixing plate 6, the inside of the first fixing plate 6 is slidably connected to the second fixing plate 7, the second fixing plate 7 is fixedly connected to the second clamping rod 2, the inside of the second fixing plate 7 is slidably connected to a movable plate 8, and a second spring 9 is fixedly connected between the movable plate 8 and the second fixing plate 7, the bottom of the movable plate 8 is fixedly connected to a first contact 10, the bottom of the inner wall of the first fixing plate 6 is fixedly connected to a second contact 11, and the inside of the second clamping rod 2 is fixedly connected to a timer 12. In addition to including a small display screen for display, the timer 12 also has a small display screen located on the small display screen. The switch adjustment buttons on both sides are used to start and stop and adjust the timing time. The user can choose to start or stop the timer 12 as needed to avoid the situation where the blood vessel clamp will cause an alarm and timing during the empty clamping process. A buzzer 13 is fixedly connected inside the second clamping rod 2 and between the pinching piece 4 and the timer 12. The first contact 10, the second contact 11 and the buzzer 13 are all electrically connected to the timer 12. When the first contact 10 and the second contact 11 are pressed tightly, the timer 12 starts timing and an alarm is issued through the buzzer 13. Under normal circumstances, the first contact 10 and the second contact 11 are not in contact. After clamping the blood vessel, the first contact 10 is in contact with the second contact 11. China Patent has long disclosed a capsule oil storage cabinet with patent number CN201822040175.1. The specification records in detail the control and process of the first contact 10 and the second contact 11 on the buzzer 13. They are all existing well-known technologies and will not be elaborated here.

[0022] Furthermore, the internal thread of the first clamping rod 1 is connected to a threaded rod 14, and a groove 15 is provided on the inner side of the second clamping rod 2 close to the threaded rod 14. The groove 15 is used in conjunction with the threaded rod 14. The threaded rod 14 is located on the inner side of the groove 15, and a knob is provided at one end of the threaded rod 14. The user can lock the second clamping rod 2 by tightening the threaded rod 14.

[0023] Furthermore, teeth 16 are fixedly connected to the outside of the first clamping rod 1 and the clamping head 3. The teeth 16 help the clamping head 3 to cooperate with the first clamping rod 1 to clamp the blood vessel more tightly and not easily loosen.

[0024] Furthermore, an anti-slip groove 17 is provided on the inner side of the pinching piece 4 away from the first spring 5 . The anti-slip groove 17 helps to increase the friction between the user's hand and the pinching piece 4 to prevent the pinching piece 4 from slipping out of the hand.

[0025] Furthermore, the first fixed plate 6, the second fixed plate 7 and the movable plate 8 are all arc-shaped structures, and the first clamping rod 1 and the second clamping rod 2 are connected by a rotating shaft.

After releasing the pinching piece 4, the elastic force of the first spring 5 drives the clamping head 3 to approach the first clamping rod 1, and cooperates with the teeth 16 to clamp the blood vessel. At this time, the first contact 10 and the second contact 11 are pressed tightly, and the timer 12 is turned on to start timing. After the timing is over, the buzzer 13 sounds an alarm, thereby achieving the purpose of automatic timing. The utility model is convenient to use, simple to operate, and highly practical.
