Description
Technical Field
The invention relates to the field of surgical hemostasis tools, in particular to a compression hemostasis tool for a great saphenous vein stripping operation.
Background
The great saphenous vein varicosity is caused by the fact that superficial vein blood flows backwards due to incomplete closure of a superficial vein valve and the pressure of a lower limb vein is increased. Congenital weakness of the vein wall is also an important reason, patients often have systemic or local vein wall defects, and in the case of increased vein pressure, the vein is circuitous and dilated, and particularly, the factors of standing time, obesity and increased abdominal pressure which can increase the vein pressure of the lower limb can cause varicose veins to occur. At present, common operations for patients with obvious lower limb symptoms comprise great saphenous vein denudation and great saphenous vein radiofrequency ablation.
The great saphenous vein denudation is a traditional standard operation type for treating primary great saphenous vein varices, but has the defects of large wound, much bleeding and the like, and causes slow recovery and long hospitalization time. The operation needs to press the great saphenous vein stripping area through external force in the operation, thereby achieving the purposes of closing the branch blood vessel of the vein as much as possible and reducing bleeding of the stripping area.
Chinese patent No. 201921453169.7 discloses an adjustable great saphenous vein compressor, which is suitable for great saphenous vein radio frequency ablation, and comprises a handle movably connected with a support, the handle penetrates through the support, a first universal joint is arranged at one end of the handle and fixedly connected with the handle, an auxiliary pressing sheet is arranged at one side of the first universal joint and fixedly connected with the first universal joint, and a second universal joint is arranged at one end of the support; the first water bag and the second water bag are adapted to the contour of the thigh, and simultaneously, the pressing force is dispersed, so that the stress of the cauterized area is uniform.
The compressor realizes compression hemostasis on veins to a certain extent, so the compressor is also suitable for stripping great saphenous vein. However, the wound of the great saphenous vein stripping operation is large, the bleeding is more, the stripping area needs larger external pressure to compress for hemostasis, the leg lengths of different patients are different, the device easily enables the compressed area to be insufficient, and therefore the postoperative hemostasis effect is poor.
