Abstract
Description
Technical Field
[0001] This invention relates to the field of abdominal aortic occlusion vascular clamp technology, specifically a vascular clamp suitable for abdominal aortic occlusion and catheter placement. Background Technology
[0002] Abdominal aortic occlusion is a high-risk emergency or elective medical procedure primarily used to control life-threatening massive bleeding in the abdominal or pelvic cavity, or to provide a bloodless surgical field in certain major surgeries. It temporarily blocks blood flow to the abdominal aorta through physical means. During the procedure, vascular clamps are used to apply the occlusion.
[0003] A search revealed Chinese patent application number "CN202211665542.1," which specifically describes a vascular clamp suitable for abdominal aortic occlusion and catheter placement. The clamp includes two hinged arms, each with a clamp head. Each clamp head has two spaced-apart clamp portions. The two clamp portions on one clamp head correspond one-to-one with the two clamp portions on the other clamp head, forming two sets of clamping elements. One of the clamp portions forming one set of clamping elements has an elastic element and an adjusting element. The elastic element is located on the side of the clamp portion near the other clamp portion forming the clamping element. The adjusting element is connected to the elastic element and can adjust the clamping distance between the elastic element and the clamp portion while the other set of clamping elements is in a clamping state. This invention, through two sets of clamping elements, can open and close both ends of the abdominal aorta during surgery, thereby effectively blocking and controlling abdominal aortic blood flow during abdominal organ harvesting surgery. This greatly simplifies the surgical procedure for establishing an abdominal aortic perfusion system, reduces organ ischemia time, and improves the quality of donor organs.
[0004] The existing method uses two clamps to block the suction tube and a spring plate to improve the stability of the blockage, which facilitates the operation of the abdominal aortic perfusion system and helps with catheter placement. However, by turning the screw, the spring plate is passively released from the blood vessel. Since the screw and spring plate are located near the suction tube, medical staff can easily bring bacteria from their hands into contact with the blood vessel when using their hands to control the screw, which may lead to cross-infection.
[0005] Therefore, this invention proposes a vascular clamp suitable for abdominal aortic occlusion and catheter placement to solve the aforementioned problems. Summary of the Invention

[0029] This invention provides the following technical solutions:
[0030] Example 1
[0031] Please see Figure 1 - Figure 5A vascular clamp suitable for abdominal aortic occlusion and catheter placement includes a clamp handle 1 and a clamp handle 4. A rectangular groove 2 is provided on the upper side of the clamp handle 1. A rotating shaft 3 is rotatably connected to the inner side of the rectangular groove 2. The rotating shaft 3 is fixedly connected to the clamp handle 4. A handle portion 8 is fixedly connected to the outer side of both the clamp handle 1 and the clamp handle 4. A locking block 9 is fixedly connected to one side of the clamp handle 1. A locking block 10 is fixedly connected to the side of the clamp handle 4 near the locking block 9. A clamp head 5 is fixedly connected to the right side of the clamp handle 1. A clamp head 6 is fixedly connected to the right side of the clamp handle 4. A stabilizing unit 7 is provided on the outer side of the clamp head 6. The stabilizing unit 7 is used to make the occlusion more stable and convenient to operate. When occluding the blood vessel, the clamp heads 5 and 6 on both sides are rotated and the locking blocks 9 and 10 are used to limit the clamp heads 5 and 6, which facilitates subsequent catheter placement.
[0032] The stabilizing unit 7 includes a mounting plate 79, which is fixedly connected to the front side of the clamp head 6. Side blocks 716 are fixedly connected to both the upper and lower sides of the mounting plate 79. Contact plates 717 are provided on the outer sides of both side blocks 716. A fixing plate 721 is fixedly connected to the front side of the contact plate 717. A connecting plate 722 and a mounting block 713 are fixedly connected to the outer side of the fixing plate 721. A side plate 71 is fixedly connected to the left side of the mounting block 713. An L-shaped block 72 is fixedly connected to the left side of the side plate 71. A fixing block 75 is fixedly connected to the outer side of the L-shaped block 72. A locking rod 74 is provided on the upper side of the L-shaped block 72. A control device is fixedly connected to the upper end of the locking rod 74. Block 76, control block 76 and fixed block 75 are fixedly connected by a spring 77, the upper side of control block 76 is fixedly connected by a pull plate 78, the upper side of clamp handle 4 is provided with a locking hole 73, the number of locking holes 73 is set to two, the locking rod 74 is slidably connected to L-shaped block 72, the contact plate 717 is slidably connected to side block 716, the contact plate 717 is made of rubber material, the outer side of clamp head 6 is fixedly connected by a sliding rod 714, the sliding rod 714 is slidably connected to mounting block 713, the front side of mounting plate 79 is fixedly connected to a protective box 710, the upper and lower sides of the protective box 710 are provided with multiple through holes 711, the left side of the protective box 710 is... A second perforation 712 is provided on the side. A second spring 715 is fixedly connected between the mounting block 713 and the second clamp head 6. The lower side of the pull plate 78 extends to the handle part 8. Both the first clamp head 5 and the second clamp head 6 have protrusions fixedly connected to their outer sides. Both the first clamp head 5 and the second clamp head 6 are inclined structures. When the second clamp head 6 and the first clamp head 5 block the blood vessel, the medical staff pulls the pull plate 78 to rise. The pull plate 78 drives the control block 76 to move, and the control block 76 drives the locking rod 74 to move, causing the locking rod 74 to separate from the locking hole 73. Since the second spring 715 is in a compressed state at this time, when the locking rod 74 separates from the locking hole 73, the second spring 715 drives the mounting block 712 to move. 13 moves backward, the mounting block 713 drives the side plate 71 to move backward, the side plate 71 drives the L-shaped block 72 to move backward, the L-shaped block 72 drives the locking rod 74 to move backward. When the locking rod 74 moves to the locking hole 73 on the other side, under the action of the spring 77, the spring 77 drives the locking rod 74 to lock into the locking hole 73, causing the mounting block 713 to move backward and be limited. The mounting block 713 drives the fixing plate 721 to move backward, the fixing plate 721 drives the contact plate 717 to move backward, so that the contact plates 717 on both sides move backward and contact the blood vessel, improving the blocking effect. When reinforcing, the medical staff's hands are located at the handle part 8, and will not contact the blood vessel, reducing the risk of cross-infection.
[0033] Example 2
[0034] Based on Example 1, such as Figure 6 - Figure 8As shown, stabilizing blocks 718 are provided on the outer sides of both contact plates 717. Control plates 719 are fixedly connected to the outer sides of both stabilizing blocks 718. Moving blocks 720 are fixedly connected to the outer sides of both upper and lower control plates 719. Stabilizing blocks 718 are slidably connected to contact plates 717. Stabilizing blocks 718 are made of rubber material. A rotating rod 723 is rotatably connected to the outer side of a fixed plate 721. A turntable 724 is fixedly connected to the front end of the rotating rod 723. Two rotating blocks 725 are fixedly connected to the outer side of the turntable 724. An inclined plate 726 is rotatably connected to the front side of the rotating block 725. Two movable blocks 720 are rotatably connected to the front of a connecting rod 727, which is fixedly connected to an inclined plate 726. A groove 729 is provided on the outer side of the fixed plate 721, and a slider 730 is slidably connected to the inner side of the groove 729. A base block 728 is fixedly connected to the lower end of a rotating rod 723, and an inclined plate 731 is rotatably connected to the lower side of the base block 728. The inclined plate 731 is rotatably connected to the slider 730. Two linkage plates 732 are rotatably connected to the outer side of the slider 730, and a connecting block 733 is rotatably connected between the two linkage plates 732. The rear side of the connecting block 733... A lifting block 734 is fixedly connected. A telescopic rod 735 and a spring 736 are fixedly connected between the lifting block 734 and the fixed plate 721. A pressure block 737 is fixedly connected to the rear side of the lifting block 734. When the fixed plate 721 moves backward, the fixed plate 721 drives the lifting block 734 to move, and the lifting block 734 drives the pressure block 737 to move backward. When the pressure block 737 contacts the side block 716, the fixed plate 721 continues to move backward, and the pressure block 737 drives the lifting block 734 to move forward. The lifting block 734 drives the linkage plate 732 to rotate, and the linkage plate 732 drives the slider 730 to move. Block 730 drives inclined plate 2 731 to rotate, inclined plate 2 731 drives rotating rod 723 to rotate counterclockwise, rotating rod 723 drives turntable 724 to rotate, turntable 724 drives rotating block 725 to rotate, rotating block 725 drives inclined plate 1 726 to rotate. Since the two inclined plates 1 726 are arranged in parallel, inclined plate 1 726 drives moving block 720 to move, moving block 720 drives control plate 719 to move, control plate 719 drives stabilizing block 718 to move, and the stabilizing blocks 718 on the upper and lower sides move closer to each other, so that the stabilizing blocks 718 block the blood vessel again, further improving the blocking effect.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] Working principle: First, the blood vessel is blocked by clamp head 5 and clamp head 6. Then, the medical staff pulls the pull plate 78 to rise, which drives the clamp rod 74 to rise, separating the clamp rod 74 from the clamp hole 73. Under the action of spring 1 77 and spring 2 715, the mounting block 713 moves backward, which drives the contact plate 717 to move backward, so that the two contact plates 717 squeeze the blood vessel and improve the blocking effect. The operation is simple. At the same time, the fixing plate 721 drives the pressure block 737 to move backward. Under the action of the lifting block 734, the linkage plate 732, the slider 730, the inclined plate 2 731, the rotating rod 723, the turntable 724 and the inclined plate 1 726, the stabilizing blocks 718 on the upper and lower sides move closer to each other, so that the stabilizing blocks 718 further block the blood vessel.
