An anastomosis cuff

Abstract

The invention discloses a hooping barrel for inosculation, which comprises a first half barrel, a second half barrel and a rotating shaft, wherein the first half barrel comprises a stop part and a first rotating shaft part which are arranged at both edges of the first half barrel in the circumferential direction; spines are formed on the inner wall of the first half barrel; the stop part comprises an inosculation passage; an inosculation tooth is formed in the inosculation passage; the first rotating shaft part is provided with a first center hole; the second half barrel comprises a guide part and a second rotating shaft part which are arranged at both ends of the second half barrel in the circumferential direction; oblique teeth and spines are formed on the inner wall of the second half barrel; sizes of a thickness and a width of the guide part along the circumferential direction of the second half barrel are gradually reduced; the second rotating shaft part is provided with a second center hole; the rotating shaft passes through the first center hole and the second center hole, and the rotating shaft, the first rotating shaft part and the second rotating shaft part form a hinge structure. By applying the hooping barrel, operation steps can be obviously reduced, operation time is saved, more doctors and hospitals can develop an minimally invasive esophageal surgical technology, further, operation cost is reduced, and an economic load of a surgical patient is reduced.

Description

technical field [0001] The invention relates to the field of medical operation consumables, in particular to a surgical operation auxiliary device applied to digestive tract anastomosis, especially for the gastroesophageal intrathoracic anastomosis process of transorally implanted nail-anvil system in minimally invasive esophageal cancer radical resection A hoop for anastomosis. Background technique [0002] During the operation of digestive tract reconstruction, it is usually necessary to shrink the stump of the digestive tract so that the main body of the stapler and the anvil will not come out, and the two segments are in full contact during the anastomosis so that no side holes are left after the anastomosis. Especially in the process of intrathoracic gastroesophageal anastomosis with peroral implantation of nail-anvil system in minimally invasive radical resection of esophageal cancer, the treatment of esophageal stump is more difficult due to the limitation of endoscop...

Problems solved by technology

[0004] The disadvantages of the current technology with respect to the application of this device are: 1. Performing anastomosis on the wound is not conducive to the blood supply of the anastomotic stoma, thus affecting the healing of the anastomotic stoma; Lead to wound infection and increase the risk of anastomotic leakage after operation; 3. This anastomosis is not strictly end-to-side anastomosis but side-to-side anastomosis, which is more likely to cause anastomotic leakage than end-to-side anastomosis; 4. Above the incision The opening operation is more difficult and time-consuming, and too large opening may lead to the risk of anvil prolapse; 5. The cutting and stapler is expensive, and the burden on patients is heavy

[0005] Secondly, there are also some experts who use manual purse-string suture of esophageal stump under thoracoscopic surgery, but the disadvantages of this technique compared with this device are: 1. The manual purse-string suture technique is quite difficult and requires thoracic surgeons with rich endoscopic skills. 2. Manual purse-string suture under thoracoscopic surgery is very time-consuming, which indirectly increases the risk of surgery; 3. Manual purse-string suture has a higher risk of anastomotic leakage
