[0056] The effective length of the collection sleeve is 20-45cm, and the outer diameter is 9-20mm; the outer surface of the sleeve is a prismatic surface; the diameters of the scissors through hole and the endoscope through hole are respectively 4-9mm; the length of the handle is 8-1...

Embodiment 3

[0059] Embodiment 3: A method for collecting blood vessels through a low-temperature endoscope, comprising the following steps;

[0060] First insert the endoscope 2 into the free sleeve 20, and install the free head 21;

[0061] Put the short-mouthed trocar 11 on the cannula 20, insert the free head 21 into the surgical site through the short-mouthed trocar 11, and push it toward the target;

[0062] After the free head 21 reaches the operation position, take out the free sleeve 20, and pull out the endoscope 2 therefrom;

[0063] Insert the endoscope 2 into the endoscope through hole 3 of the collection cannula, and insert low-temperature electrocoagulation scissors or bipolar scissors into the scissors through hole 10. Insert the collection cannula through the short-mouth trocar 11 into the surgical site;

[0064] Under the monitoring of the endoscope 2, push the c-ring 5 to the target blood vessel. If the lens is blurred by blood or fat, connect the cleaning solution inje...

Abstract

The invention discloses a low temperature endoscope blood vessel collecting device and method, and belongs to the technical field of medical treatment. A rigid tube endoscope is structurally composed of a steel tube. A lens for collecting images is arranged at the tip of the steel tube. The tail end is provided with threads and used for being connected with a collecting casing pipe and a free casing pipe and fixed. A light guiding connector connected with optical fiber and a connecting device connected with a video camera are arranged on the endoscope. A short-opening trocar is structurally characterized in that an annular air bag is connected to the periphery of the shell, the annular air bag is wrapped by rubber, the main shell is connected with an annular air bag inflation opening and a carbon dioxide tube end, the top end of the main shell is connected with a body seal, and the carbon dioxide tube end is connected with a CO inlet. The device has the advantages that the bridge blood vessel perfectness ratio is improved, hidden bridge blood vessel injuries are avoided, the bypass surgery successful rate is increased, the bridge blood vessel re-blocking probability is decreased, and therefore the survival time of a patient is prolonged.

Description

technical field [0001] The invention relates to a low-temperature endoscope blood vessel collection device and method, belonging to the field of medical technology. Background technique [0002] In bypass surgery, a graft 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. The patient suffers a lot, the postoperative recovery time is long, the chance of infection is high, the pain is intense and lasts for a long time, and the scar is obvious. [0003] Now the minimally invasive endoscopic blood vessel harvesting system can help doctors perform minimally invasive surgery on the legs or arms. The do...
