Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0028] When the auxiliary component of the thoracic duct and azygos anastomosis is implemented, it can perform winding traction on the periphery of the thoracic duct and / or azygos vein, providing assistance for the operator to perform subsequent side-to-side anastomosis of the thoracic duct and azygos vein.

[0029] Such as Figures 1 to 6 As shown, an auxiliary assembly for thoracic duct and azygos anastomosis includes a bow 1 and a draw bridge 2, and the upper and lower ends of the draw bridge 2 are respectively rotatably arranged at the two ends of the bow 1, so that the bow The device 1 and the traction bridge 2 form a temporary gap that can accommodate the thoracic duct and / or the azygos vein 6. The upper end of the traction bridge 2 can automatically reset and rotate toward the outside of the temporary gap, and its lower end can automatically r...

Abstract

The invention discloses an auxiliary assembly for chest catheter and odd vein anastomosis. The auxiliary assembly comprises an arch-shaped device and a traction bridge; the upper end and the lower end of the traction bridge are rotatably arranged at the two ends of the arch-shaped device correspondingly, such that a temporary gap capable of containing a chest catheter and / or an odd vein is formed by the arch-shaped device and the traction bridge; the upper end of the traction bridge can rotate towards the outer side of the temporary gap in an automatic reset mode, and the lower end of the traction bridge can rotate towards the inner side of the temporary gap in an automatic reset mode; the upper end of the traction bridge is provided with a rope penetrating portion through which at least one rope can penetrate; and the lower end of the traction bridge is provided with a fixing portion for fixing the rope. The auxiliary assembly can assist a surgeon to perform winding traction on a chest catheter and / or odd veins before performing side-side anastomosis of chest catheter and odd vein anastomosis, the operation space is optimized, and traction protection is performed on human body vessels.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary assembly for thoracic duct and azygos anastomosis. Background technique [0002] The thoracic duct is the largest lymphatic vessel in the body and is responsible for transporting lymph fluid from the intestinal lymphatic system, peritoneum, abdominal wall, and lower extremities. The upper and lower segments of the thoracic duct are adjacent to the mediastinal pleura, so chylothorax can be caused when the thoracic duct is damaged with mediastinal pleura damage. Chyle leaks can lead to continuous fluid loss and a reduction in serum albumin, and can also lead to a marked decrease in peripheral lymphocytes, with concomitant damage. [0003] If thoracic duct injury or chyle fluid leakage is found during thoracic surgery, or thoracic duct injury is highly suspected, the thoracic duct can be ligated to prevent postoperative chylothorax. [0004] Thoracic duct liga...
