Embodiment 1
[0014] see Figure 1-Figure 6 , a ring-shaped smoke aspirator on the incision protective cover, which is composed of a ring-shaped suction pipe 1, a ring-shaped slot 2, a connecting pipe 3 and an opening 4, and its material is medical elastic silicone. The annular suction tube 1 is an annular hollow tubular structure, and the openings 4 are evenly distributed on the inner wall of the annular suction tube 1, so that surgical smoke can be inhaled in all directions (such as figure 2 and Figure 5 shown). Said annular slot 2 is an annular semi-tubular structure, its size is slightly larger than the annular suction tube 1, located directly below the annular suction tube 1 and integrally connected (such as Figure 1-Figure 3 As shown), the annular slot 2 has elasticity, and rubber or silica gel can be selected for use. Press the annular card slot 2 on the elastic circular ring of the incision protective sleeve by hand, the annular card slot 2 is stretched, and after the elastic ...
Embodiment 2
[0016] During the operation, after the incision protective cover is fixed, you can choose the ring-shaped smoke aspirator of the corresponding specification according to the size of the incision protective cover, and buckle the annular card slot 2 of the annular smoke aspirator on the elastic circular ring of the incision protective cover fixed (see Figure 6 ), connect the suction tube at one end of the connecting tube 3 of the suction device, and connect the negative pressure suction device, and the assembly is completed. During the operation, due to the effect of the negative pressure suction device, a negative pressure will be formed around the surgical incision, and the surgical smoke generated by the electric knife will be sucked into the opening 4 on the annular suction tube 1, and pass through the annular suction tube 1, The connecting tube 3 and the external suction tube are recovered.
