Description
Technical Field
The invention relates to the technical field of blood vessel collecting devices, in particular to a blood vessel collecting device.
Background
In bypass surgery, a bypass vessel (target vessel) must be harvested from the patient, and the great saphenous vein or radial artery is now commonly selected. In conventional surgery, the skin and muscle tissue are completely peeled off, and the target blood vessel is separated from the collateral blood vessel under direct vision. Surgery typically involves making an incision in the leg or arm of the patient, typically 20-25cm, corresponding to the length of the target vessel. The patients have large wounds in operation, long recovery time after operation, large chance of infection, strong pain feeling and long duration, and the scars are obvious after recovery. The current minimally invasive endoscopic vessel collection system can help doctors to perform minimally invasive surgery on legs or arms, and the doctors can easily take out the required target vessel by only making 1-2 small incisions of 1-2cm on the legs or the forearms of the patients. The method has the advantages of very small wound in the operation of the patient, reduced infection and complication probability, reduced pain, shortened postoperative recovery time, and more beautiful appearance.
Chinese patent CN106943175A discloses a minimally invasive saphenous vein collection device, a vascular protective sleeve is inserted into a sleeve cutter, and the sleeve cutter is inserted into a tissue fixing sleeve; the first gear at the tail end of the sleeve cutter is positioned outside the tail end of the tissue fixing sleeve, and the first gear is screwed on the external thread at the tail end of the vascular protecting sleeve by the internal thread; the transmission device comprises a front supporting body and a rear supporting body, the tail end of the tissue fixing sleeve is fixed at the front through hole of the front supporting body, and the tail end of the blood vessel protecting sleeve is fixed at the rear through hole of the rear supporting body; a rotating shaft and a second gear meshed with the first gear are arranged between the front support body and the rear support body; the driving device is connected with the rotating shaft. The invention has simple structure, reasonable design and low cost; the operation is simple and easy to master; the wound to the patient is small, and the safety is high; the vein collection time is short, the average collection time of each blood vessel is 2-3 minutes, the time is only 1/10 of that of the current best endoscope collection system, and the operation efficiency is improved.
However, when the great saphenous vein acquisition device acquires a blood vessel, the guide wire needs to pass through the blood vessel to be acquired firstly, two ends of the guide wire are fixed through the fixing equipment, then the blood vessel is separated and acquired through the great saphenous vein acquisition device, the guide wire cannot be fixed through the great saphenous vein acquisition device, so that more equipment is needed during operation, the operation flow is complex, and the use is inconvenient.
