The utility model discloses an automobile bearing production rust-proof device which comprises a box body, a cover plate is detachably arranged on the upper end face of the box body, a supporting plate is detachably arranged in the box body, supporting rods are arranged on the left side and the right side of the upper end face of the supporting plate, and a plurality of sets of bearing bodies are detachably arranged on the two supporting rods. A plurality of partition plates are detachably arranged above the two bearing bodies on the same horizontal plane, through holes are symmetrically formed in the multiple partition plates corresponding to the supporting rods, mounting rods are arranged at the four corners of the lower end face of each supporting plate, and mounting holes corresponding to the multiple mounting rods are formed in the inner wall of the bottom end of the box body; the bottom end of the cover plate is provided with clamping sleeves corresponding to the two supporting rods and the partition plate at the topmost end, operation holes are formed in the two supporting rods, through the design of the partition plates, surface scratch or damage caused by mutual contact, collision or friction of the bearing body in the transportation, storage or treatment process is effectively prevented, and the precise surface of the bearing is protected to the maximum extent.

An auxiliary device for proximal aortic anastomosis in coronary artery bypass grafting (CABG) includes a puncture needle, a puncture cannula, a cutting cannula, and a ring compressor. The puncture cannula is fitted over the puncture needle, with a bulging ball at its tip and an annular groove at its tail end. The ring compressor is fitted over the puncture cannula and can slide axially; its tip has a notched compression ring with an inner diameter smaller than the outer diameter of the bulging ball. During puncture, after the aorta is penetrated, the ring compressor is pressed down, and the compression ring and bulging ball work together to clamp the puncture site, achieving a bloodless procedure. The cutting cannula is then pressed down, and the aortic wall within the compression ring is removed. The graft vessel is then anastomosed to the aorta, with the suture passing through the compression ring. After suturing, the ring compressor is rotated, and the suture exits through the notch. The entire device is then withdrawn, and the suture is tightened and knotted to complete the anastomosis. This invention avoids aortic clamping, eliminates the risk of plaque dislodgement, requires only a single port for anastomosis, and is simple to operate with reliable hemostasis.
