Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

First embodiment

Please refer to fig. 1, fig. 2, fig. 3 and fig. 4 in combination, wherein fig. 1 is a schematic structural view of a first embodiment of a puncturing device for cardiothoracic surgery according to the present invention; FIG. 2 is a schematic view showing an internal structure of the buffer tube shown in FIG. 1; FIG. 3 is a schematic structural view of the sleeve shown in FIG. 1; fig. 4 is a schematic view of the arcuate member shown in fig. 1. A puncture device for cardiothoracic surgery, comprising:

a connecting cylinder 1;

the sleeve 2 is sleeved on the outer surface of the connecting cylinder 1, two mounting grooves 3 are formed in the outer surface of the sleeve 2, two nuts 4 for fixing are respectively arranged on the outer surfaces of the mounting grooves 3, the inner walls of the two nuts 4 are in threaded connection with screw rods 5 for fixing, one sides of the two screw rods 5 opposite to each other penetrate through one sides of the mounting grooves 3 and extend to the other sides of the mounting grooves 3, arc-shaped parts 6 for fixing are fixedly connected to one sides of the two screw rods 5 opposite to each other, and one sides of the two arc-shaped parts 6 opposite to each other are in contact with the outer surface of the connecting cylinder 1;

the fixing ring 7 is arranged at the bottom of the sleeve 2, thin rods 8 are fixedly connected to one side, opposite to the sleeve 2, of the fixing ring 7, a buffer cylinder 9 is movably connected between the two thin rods 8, an elastic part 10 is arranged inside the buffer cylinder 9, and the top and the bottom of the elastic part 10 are fixedly connected with the thin rods 8;

the external shape of the sleeve 2 is cylindrical, the purpose of which is to avoid the hands of the doctor from being scratched because the surface of the cylinder is smoother;

the nut and the screw rod can effectively fix the connecting cylinder on the arc-shaped part based on the sleeve;
