Great saphenous vein minimal invasion segmented harvesting assisting device

Abstract

The invention discloses a great saphenous vein minimal invasion segmented harvesting assisting device. The assisting device comprises a cross bar, support plates and dilators, wherein the cross bar runs through two support plates which are arranged in parallel at an interval, and the inner surface of each support plate is provided with the dilator in an extending manner. When the assisting deviceis applied to segmented harvesting of a great saphenous vein, the incision length can be shortened, and the length of a subcutaneous tunnel is prolonged, so that a surgical scar on a leg after a surgery can be nice; and furthermore, operation can be performed by a single person when the great saphenous vein in the subcutaneous tunnel is dissociated, tissues are clearly exposed, sufficient hemostasis is realized after surgery, and damage on the great saphenous vein can be avoided.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an auxiliary device for minimally invasively obtaining great saphenous vein graft vessels in coronary artery bypass surgery. Background technique [0002] In recent years, with the aggravation of population aging and the obvious prevalence of cardiovascular disease risk factors, the incidence of coronary heart disease has increased year by year, and the base of patients requiring coronary artery bypass grafting has increased. The great saphenous vein is an important vascular medium in coronary artery bypass surgery. The method of obtaining the great saphenous vein used to use conventional incisions to obtain the great saphenous vein. The wound surface is large and the bleeding is large. Poor healing of the incision often occurs after surgery, and postoperative incision scars Often from the ankle to the root of the thigh, it affects the appearance very much. Although there is lapar...

Problems solved by technology

The great saphenous vein is an important vascular medium in coronary artery bypass surgery. The method of obtaining the great saphenous vein used to use conventional incisions to obtain the great saphenous vein. The wound surface is large and the bleeding is large. Poor healing of the incision often occurs after surgery, and postoperative incision scars Often from the ankle to the root of the thigh, which greatly affects the appearance

Although there is laparoscopic access to the great saphenous vein technology, on the one hand, it needs the support of relevant endoscopic equipment, on the other hand, it will increase the cost of surgery for patients, and the surgeon needs to be trained to master this technology

The minimally invasive segmental access to the great saphenous vein does not require laparoscopy and consumables, and the operator can master it after simple training. Injury, affecting the quality of blood vessels, incomplete hemostasis of blood vessel stumps, often leads to postoperative hematoma, and even poor incision healing or even incision infection, so assistants are often needed to help expose
