The utility model relates to the technical field of milling machine fixtures, in particular to a milling machine fixture which comprises a base and a sliding block arranged on the base in a sliding mode, a fixed clamping plate and a movable clamping plate are further arranged on the base, the fixed clamping plate is fixedly installed on one side of the base, and the movable clamping plate is fixedly installed on the sliding block. A first air cylinder is fixedly installed on the base, and a piston rod of the first air cylinder is connected with the sliding block. The base is provided with a bearing face, a penetrating opening is formed in the bearing face, and a bearing piece is arranged at the penetrating opening, the bearing piece is used for assisting a workpiece in entering and exiting from a clamping area, contact between a worker and a clamp can be effectively reduced, and the worker is prevented from being hurt by clamping force of the clamp due to the fact that the workpiece is manually placed in the operation process; through the assistance of the bearing plate, the workpiece can enter a clamping area safely and stably and retreat smoothly after machining is completed, and safety and working efficiency are effectively improved.

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.

The invention discloses a flexible RF coaxial line feeding device and a using method thereof.The feeding device comprises a stock bin mechanism, a grabbing mechanism and a visual module, and the grabbing operation of the grabbing mechanism is achieved in the downward pressing process; the profiling clamping blocks are pressed downwards by means of the self weight under the overshoot springback effect of the sliding rod, so that the coaxial line in the concave stock bin of the stock bin mechanism is squeezed into the profiling opening, and therefore impact of instant pressure on the coaxial line in the concave stock bin is reduced, and the possibility that the coaxial line is squeezed and damaged due to the fact that the pressure is too large is reduced. A profiling clamping block with a profiling opening and a connecting rod clamping jaw are matched with a telescopic transverse rod which is connected to an opening and closing assembly of a stock bin mechanism and transversely arranged above a clamping position through double clamping under the condition that the visual module recognizes the number and posture of coaxial lines clamped by the profiling opening, and it is jointly guaranteed that the device can grab a single axis.
