[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Example 1
[0020] Reference Figure 1-4A blood vessel clamping device comprises a hand-held rod 1, a groove 2 is provided on one side of the hand-held rod 1, fixed blocks 3 are arranged on both sides of one side of the hand-held rod 1, rotating rods 4 are placed on the two fixed blocks 3, the two rotating rods 4 can be rotatably arranged on the fixed blocks 3, one end of the two rotating rods 4 extends into the groove 2, an adjustment mechanism is arranged between the two rotating rods 4 in the groove 2 and the hand-held rod 1, the other end of the two rotating rods 4 is installed with a clamping block 12, the adjustment mechanism comprises a moving block 5 slidably arranged in the groove 2, the moving block 5 is arranged on the fixed block 3, and the moving block 5 is arranged on the fixed block 3. Lifting blocks 6 are installed on both sides of one side of the moving block 5, and one side of the two lifting blocks 6 is opened in an inclined shape. One end of the two rotating rods 4 is squeezed on the inclined sides of the two lifting blocks 6, and a sliding rod 7 is installed on one side of the moving block 5. The sliding rod 7 slides through the hand-held rod 1 and extends to the outside of the hand-held rod 1. Elastic ropes 8 are provided at one end of the two rotating rods 4, and one end of the elastic ropes 8 of the two rotating rods 4 is provided on the hand-held rod 1. A partition 11 is installed in the groove 2, and one side of the two lifting blocks 6 slides and is squeezed on the partition 11.
[0021] Combined with Figure 2 It can be seen that there are two elastic ropes 8 on one side of the rotating rod 4, and the two elastic ropes 8 are symmetrically arranged, so that after one of the elastic ropes 8 breaks, the other elastic rope 8 can continue to work, making the device not easily damaged by novice medical staff.
[0022] The provided partition 11 can limit the two lifting blocks 6, so that the two lifting blocks 6 are not easy to shake in the groove 2, so that the rotation amplitude of the two rotating rods 4 is consistent, so that the clamping blocks 12 of the two rotating rods 4 are not easy to deviate during the process of clamping the blood vessel, and the partition 11 also makes it difficult for the two lifting blocks 6 and the moving block 5 to separate from the groove 2.
[0023] After the medical staff holds the hand-held rod 1 tightly, they press the sliding rod 7 with their fingers. During the movement of the sliding rod 7, the sliding rod 7 will squeeze the moving block 5, so that the moving block 5 moves in the groove 2, so that the moving block 5 will move with the lifting block 6 in the groove, so that the two lifting blocks 6 will lift one end of the two rotating rods 4, so that the two rotating rods 4 will rotate on the fixed block 3, so that the clamping blocks 12 on the two rotating rods 4 will squeeze the blood vessel, so that the blood vessel is clamped, and the excessive stretching of the elastic rope 8 will reduce the rotation amplitude of the two rotating rods 4, making it less difficult for the two rotating rods 4 to continue to apply pressure on the blood vessel, so that the blood vessel is not easily clamped off during the blood vessel clamping by the medical staff.
[0024] Example 2
[0025] Based on Example 1, optimization is performed. Figure 1-4A pressing block 9 is installed at one end of the sliding rod 7, and a fixing ring 10 is arranged at the edge of the hand-held rod 1 close to the pressing block 9. There are two fixing rings 10, and the two fixing rings 10 are symmetrically arranged around the sliding rod 7. The edges of the two fixing rings 10 and the pressing block 9 are both arranged in an arc shape, and the cross-sectional shape of the hand-held rod 1 is arranged in an elliptical shape.
[0026] Combined with Figure 1 The two fixing rings 10 on the hand-held rod 1 are arranged at the short sides of the hand-held rod, so that when the medical staff holds the hand-held rod 1, two of their fingers are respectively put on the fixing rings 10, so that the palm of the medical staff can press on the pressing block 9, so that the sliding rod 7 can move more easily on the hand-held rod 1, so that beginners can also easily operate the device.
[0027] Overall process: when the medical staff holds the hand-held rod 1, two of the fingers are respectively put on the fixed ring 10, so that the medical staff's palm can press on the pressing block 9, and the sliding rod 7 will squeeze the moving block 5 during the movement, so that the moving block 5 moves in the groove 2, so that the moving block 5 will move with the lifting block 6 in the groove, so that the two lifting blocks 6 will lift one end of the two rotating rods 4, so that the two rotating rods 4 will rotate on the fixed block 3, so that the clamping blocks 12 on the two rotating rods 4 will squeeze the blood vessel, so that the blood vessel is clamped, and the excessive stretching of the elastic rope 8 will reduce the rotation amplitude of the two rotating rods 4, making it less difficult for the two rotating rods 4 to continue to apply pressure on the blood vessel, so that the blood vessel is not easily clamped off during the medical staff clamping the blood vessel.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
