Background
The interventional operation is to make a wound on the artery and vein blood vessel of the human body and make the interventional device enter the operation part of the human body required to be reached through the blood vessel. Because part of the vascular wound is large, and anticoagulation and platelet medicines are used in the operation, the difficulty of the closed hemostasis and recovery of the large vascular wound is large, so the hemostasis method of the existing vascular suture system is adopted, and after the suture is knotted by a suture device, the suture knot needs to be pushed tightly to the wound part.
Currently, a suture conditioner is used for pushing tight a suture knot, such as an arterial vascular suture conditioner proposed by publication No. CN201337526Y, as shown in FIGS. 5-6, which includes a trimming switch a, a clipping switch b, a wrench c, a housing d, a hooking wire tube e, a clipping connecting rod f, and a trimming tube g.
When the suture conditioner is used, firstly, the thread clamping switch b of the conditioner is moved upwards, one end of a suture is hooked by the thread hooking pipe e, and after the thread is hooked, the suture is pressed by the thread clamping switch b under the elastic action of the rear end; then the hook wire end is pulled tightly by hand, and the prefabricated knot is pushed to the skin tissue at the puncture position.
When the device is generally used, if the stitching of the thread clamping switch b is too tight, the thread is difficult to pull or the thread is damaged when the hook thread end is subsequently tightened, and if the stitching is too loose, the thread is easy to slip out when knot is pushed, and the knot is difficult to guide and push. Therefore, when the suture knot is generally pushed and tightened, the force needs to be controlled by the experience of an operator to slowly pull the suture, the whole action process is slow, and the efficiency is low.
