Abstract

The invention relates to a laparoscope integrated great saphenous vein blood vessel collection sleeve device and method, and belongs to the technical field of cardiothoracic surgery medical treatment.A collection sleeve is fixed on a vein operation handle, and the other end of the collection sleeve is connected with a free head with a conical front end. A scissors through hole and an endoscope through hole which are arranged in parallel are connected in a sleeve of the vein operating handle. An endoscope is inserted into the endoscope through hole and is locked and fixed through a steel mirror knob. The device has the advantages that as the front end of an endoscope cavity is wrapped below the conical head, direct contact between a lens and vascular tissue can be reduced, blood is effectively prevented from contaminating the lens of the endoscope, the clear surgical field is guaranteed, use of washing liquid such as normal saline is reduced, effectiveness and safety in the surgical process are improved, and operation is easy; the frequency that the collection sleeve and bipolar electrocoagulation scissors get into and out of a human body is reduced, and the postoperative infectionrate is reduced; and the lens of the endoscope is protected, operation is convenient, the success rate of bypass surgery can be increased, the probability of re-blockage of bypass vessels is reduced,and therefore the survival time of a patient is prolonged.

Description

technical field [0001] The invention relates to a laparoscopic integrated great saphenous vein vessel collecting cannula device and method, belonging to the medical technical field of cardiothoracic surgery. Background technique [0002] In bypass surgery, a graft vessel (the target vessel) must be harvested from the patient, now usually the great saphenous vein or the radial artery. In traditional surgery, the skin and muscle tissue should be completely peeled off, and the target blood vessel and collateral blood vessels should be separated under direct vision. The operation generally requires an incision in the patient's leg or arm that is equivalent to the length of the target blood vessel, usually 20-25cm. Patients have large intraoperative trauma, long postoperative recovery time, high chance of infection, strong pain and long duration, and obvious scars after recovery. [0003] Now the minimally invasive endoscopic blood vessel harvesting system can help doctors perf...
