Sealing valve 154 and the second sealing valve 155 are semicircle in class, the top and connection of the first sealing valve 154 and the second sealing valve 155
The lower section of the lower end connection of seat 153, the first sealing valve 154 and the second sealing valve 155, which connects to each other to form, struts band.Strut band
Most weakness is connected, when surgical instrument squeezes the first sealing valve 154 or when the second sealing valve 155, band is strutted and is squeezed power
Effect struts band stress and bursts, and thus surgical instrument can pass through.
In other embodiments, the first sealing valve 154 can also be not connected to the second sealing valve 155, the first sealing valve 154
Chong Die in middle position formation with the second sealing valve 155, the overlapping by means of the first sealing valve 154 and the second sealing valve 155 is same
Sample can be good at blocking channel liner 122, play certain sealing function.When surgical instrument squeeze the first sealing valve 154 or
When the second sealing valve 155 of person, intermediate lap position is softened, and surgical instrument can smoothly enter into shell 11.
Embodiment 3
It as Figure 7-8, is a kind of incision protective sleeve 200 being used cooperatively with above-mentioned 100 body of seal closure.The incision protection
Set 200 includes channel 22, connection ring 21 and implantation ring 23, wherein connection ring 21 is set to the top in channel 22 with close for connecting
The connector 14 of sealing cover body 100, implantation ring 23 are set to the bottom end in channel 22 to be used in implant surgery notch, by means of being implanted into ring
23 sizing and withstanding effect both can guarantee that the shape of implantation ring 23 is relative constant, be unlikely to deform because of Tissue approximation；It is another
Aspect also ensures that implantation ring 23 abuts tissue or organ, it is ensured that relatively closed inside operation device.
As preferred embodiment, incision protective sleeve 200 is notch made of transparent or translucent flexible material
