Embodiment 1

[0022] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, a scissors device for cutting side branches of the great saphenous vein, the structure of the scissors is: a scissors end 2, a scissors handle 3 and a black cavity tube 1 and the like.

[0023] The structure of the scissors end 2 is: rivets fix the upper crescent-shaped scissors and the lower crescent-shaped scissors on the connecting shaft, and the material of the connecting shaft is ceramic; the upper crescent-shaped scissors have teeth distribution, and the lower crescent-shaped scissors have teeth Built-in slot 4, the built-in slot 4 is used to clamp the titanium clip of degradable material, and use the titanium clip to clamp the blood vessel; the scissors blade is sharp serrated, pressed up and down, the upper crescent-shaped scissors blade and the lower crescent-shaped scissors blade are curved The shape can cut the side branches of the great saphenous vein, and connect it to the handle of the scissors...

Embodiment 2

[0030] Embodiment 2, as figure 1 , figure 2 and image 3 As shown, a great saphenous vein side branch cutting scissors device, the following will briefly introduce the basic operation process of this embodiment.

[0031] Insert the endoscope into the free sleeve first, and install the free head.

[0032] Put the short-mouthed trocar on the cannula, insert the free head into the surgical site through the short-mouthed trocar, and then push it toward the target for freeing; insert the scissors into the through hole of the scissors, and insert the collection cannula through the short-mouthed trocar into the surgical site parts.

[0033] Under the monitoring of the endoscope, push the c-ring to the target blood vessel. If the lens is blurred by blood or fat, connect the injection port of the cleaning solution to a 5cc normal saline syringe, and push the syringe to spray physiological water from the lens flushing hole of the c-ring salt water to clean the lens.

Abstract

The invention discloses a great saphenous vein blood vessel collateral cutting scissor device and a using method, and belongs to the technical field of cardiothoracic surgery medical treatment. The structure of scissor ends is as follows: an upper crescent scissor blade and a lower crescent scissor blade are fixed on a connecting shaft by a rivet, the upper crescent scissor blade is provided withteeth, and a built-in slot is arranged in the middle of the lower crescent scissor blade; and the scissor blades are provided with sharp sawteeth and are pressed together up and down, and the upper crescent scissor blade and the lower crescent scissor blade are bent. The structure of scissor handles is designed based on human engineering, operation obstacles can be reduced, operation is easy and convenient, and mastering is easy. The device has the advantages that the perfectness ratio of a bridge blood vessel is increased, and the hidden damage caused to the bridge blood vessel when a high-temperature electrocoagulation method is adopted to stop bleeding of a collateral blood vessel and disconnect the collateral blood vessel is avoided; and the blocking of the great saphenous vein collateral blood vessel is realized completely through physical clamping of a degradable titanium clamp, and the physical pressing, shearing, separating and ligation are achieved through the scissor ends, sothat the success rate of the bypass surgery can be increased, the re-blockage probability of the bridge blood vessel is reduced, and the survival time of a patient is prolonged.

Description

technical field [0001] The invention relates to a great saphenous vein side branch cutting scissors device and a using method, which belong to the technical field of medical equipment. 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 suffer from severe intraoperative pain, long postoperative recovery time, a high chance of infection, intense and long-lasting pain, and obvious scars. [0003] Now the minimally invasive endoscopic blood vessel harvesting system can help doctors perform minimally invasive surgery...
