Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly relates to a vascular clamp for vascular suture. Background Art

[0002] In vascular surgery, vascular suture is one of the important steps. For each suture repair, it is required to ensure that the intima of the severed blood vessels on both sides is correctly aligned. After suture, there is no blood leakage, no vascular stenosis, and the blood flow can be smooth. During the suture process, the vascular incision needs to be aligned for suture. For this reason, many vascular clamps for vascular suture have appeared on the market. For example, the Chinese utility model patent with the publication number of CN204379349 discloses a vascular tissue clamp for facilitating vascular suture, which specifically includes forceps arms, front teeth and grooves. The vascular incision is closed by the forceps arms. However, when closing, since there is an included angle between the two forceps arms, the distal distance will always be greater than the proximal distance, resulting in incomplete closure of the vascular incision, and there will be a problem of inconsistent closure degree on both sides, thus affecting the reliability of vascular suture.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model includes two acting forceps bodies that cross and are hinged to each other; the acting forceps bodies include connecting parts for hinging. The two ends of the connecting parts are respectively provided with a front rod body and a rear rod body. A front connecting column is provided on the front rod body, and a rear connecting column is provided on the rear rod body. The distance between the front connecting column and the connecting part is equal to the distance between the rear connecting column and the connecting part; a clamping rod body is provided on the front connecting column of one acting forceps body and the rear connecting column of the other acting forceps body. The front end of the clamping rod body is rotatably connected to the front connecting column, and a waist-shaped groove is provided at the rear end of the clamping rod body. The clamping rod body is movably connected to the rear connecting column through the waist-shaped groove; when in use, hold the rear end of the acting forceps body, and after applying force to close the two acting forceps bodies inward, the front rod bodies and the rear rod bodies of the two acting forceps bodies both move inward simultaneously. Furthermore, the two clamping rod bodies are driven to move inward simultaneously in a parallel posture through the front connecting column and the rear connecting column, so that each position of the clamping rod body always maintains an equal distance, and when contacting the vascular incision, it will fully close it, effectively avoiding the problem of inconsistent closing degree and improving the reliability of vascular suture.

[0014] 2. The thicknesses of the front rod body and the rear rod body of the utility model are the same, and the upper and lower surfaces both protrude from the upper and lower surfaces of the connecting part, so that the two clamping rod bodies can be fully attached without being blocked, further improving the closing reliability of the closing member; a slot penetrating the rear end thereof is provided on the clamping rod body. The front rod body and the rear rod body are both embedded in the slot. The distance between the front end of the slot and the front connecting column is greater than the distance between the front connecting column and the front end of the front rod body. The slot of the clamping rod body forms a limit with the front rod body and the rear rod body, improving the stability of the movement of the clamping rod body. At the same time, the front rod body can completely enter the slot to avoid forming a block, and the use reliability is good.

[0015] 3. On the inner side of the acting pliers body of the present utility model, there are horizontally arranged arc-shaped locking members. The arc-shaped locking members are provided with evenly distributed locking teeth. The locking teeth have a vertical blocking surface facing the acting pliers body on the corresponding side and an inward pushing inclined surface facing the other acting pliers body. The locking teeth of the two arc-shaped locking members are engaged with each other. When the two acting pliers bodies move inward, the locking teeth on the two arc-shaped locking members move inward along the inward pushing inclined surfaces without being blocked. However, when moving outward, they cannot move due to the two fitting vertical blocking surfaces, realizing one-way locking, which can effectively prevent accidental loosening when closing blood vessels and further improve the reliability of use.
