Technical Field
The utility model relates to a structure improvement technology of an IPC classification A61B17/00 surgical instrument or an A61B17/32 surgical cutting instrument, in particular to a varicose vein stripping booster.
Background
Varicose veins refer to venous tortuosity and distension due to blood stasis, weak walls of veins and other factors. Veins in various parts of the body can develop varicose veins, such as hemorrhoids are actually a kind of varicose veins, clinically visible varicose veins of the fundus of the esophagus, varicoceles, varicose veins of the abdominal wall, and the like. The most frequent site of varicose veins is in the lower extremities. It is worth emphasizing that varicose veins are secondary manifestations of other lesions. Varicose veins of the lower extremities are caused by a number of causes, the most common being simple superficial varicose veins of the lower extremities, the main cause of which is the insufficiency of the femoral saphenous valves. Another important etiology is found in primary lower limb deep vein valve insufficiency (PDVI), which often incorporates great saphenous vein valve insufficiency and often manifests itself in tortuous and distended superficial veins. In addition, the lower limb deep vein thrombosis post-syndrome occurs due to deep vein reflux disorder, shallow vein compensatory tortuosity expansion; arteriovenous fistula of lower limbs and venous malformation large bone fat syndrome can also show superficial varicose veins of lower limbs; lower vena cava reflux obstruction, such as bujia syndrome, can also lead to varicose veins of the lower extremities. Varicose veins are common peripheral vascular diseases, and are commonly found in great saphenous vein or small saphenous vein of lower limbs, and are manifested as earthworm-like blood stasis in superficial veins of lower limbs. Often these intravenous valves have been damaged and, not only do they fail to return blood normally, but they can cause backflow of blood or local dead circulation, causing the donor site tissue to tend to necrose.
Treatment of varicose veins of the lower limb is broadly divided into three categories: the first is conservative treatment: so-called conservative treatments are mainly treatments of diseases by non-surgical methods (e.g. drugs and stretch socks), only with mild great saphenous varicose veins; the second is sclerotherapy: the hardening agent is injected into the varicose vein, and the vein wall is blocked by aseptic inflammatory reaction through the irritation of the medicine, so that the purpose of varicose vein blocking is achieved, but the recurrence rate of great saphenous varicose vein after treatment is high; the third is surgical treatment: the surgical treatment comprises the treatment of the trunk of the great saphenous vein and the treatment of superficial varicose vein blocks of the lower limb, and the trunk of the great saphenous vein can be stripped or closed by adopting high-position ligation stripping, electrocoagulation, radio frequency ablation, laser and other surgical methods; for varicose vein of lower limb, sclerosant injection, small sharp knife peeling or electric coagulation of Zhang Tuan pieces can be adopted. High ligation exfoliates the trunk of the great saphenous vein and is the most thorough treatment method.

In performing varicose vein dissection procedures, it is often encountered that the operator is required to expend significant effort to pull the diseased varicose vein from both the subcutaneous and intramuscular directions. Because a plurality of vein blood vessels are closely adhered with muscle, the vein blood vessels can be torn off by using a large force. When the operator uses a softer imported plastic guidewire stripper, they pull the stripper around the guidewire on the palm. In this process, the palm of the operator is very tight and uncomfortable to wear by the guide wire. And only one square-shaped pulling aid can be used by using the stripping device of the domestic steel wire guide wire. The square pulling aid is not easy to hold and operate when hands are full of blood of a patient, and is low in efficiency.
