The specific embodiment
As shown in the figure: a kind of specimen sampling bag for laparoscopic minimal invasive operation, comprise bag 1 and trachea 2, the bag mouth of bag 1 double-decker outer and internal layer composition of serving as reasons, between skin and internal layer, form gas-filled cavity, described gas-filled cavity is communicated with trachea 2, and the other end of trachea 2 is connected with air inflation discharging control device.Air inflation discharging control device comprises a cylindric valve body 3, valve body 3 is formed by left valve barrel and right valve barrel docking, right valve barrel one end is blind end, left valve barrel one end has air-filled pore 4, described trachea 2 is connected with air-filled pore 4, the cavity that is positioned at left valve barrel is provided with baffle plate 5, and baffle plate 5 is divided into two parts by the cavity of valve body 3.On described right valve barrel sidewall, offer injecting hole, injecting hole place is filled with the rubber stopper 17 for sealing, and injecting hole is for injecting gas in the cavity of valve body 3, during injecting gas, rubber stopper 17 is extracted, then pulled piston 7 to bleed, after inflation finishes, by rubber stopper 17 jam-packs.The center of described baffle plate 5 is provided with through hole, the inwall of this through hole has female thread, in the through hole of baffle plate 5, screw and be provided with disk 18, the center of disk 18 is provided with through hole, this through hole is provided with airtight thin film 6, in the cavity of right valve barrel, be provided with piston 7, between piston 7 and right valve barrel, by spring I 8, be connected, the outside of right valve barrel blind end also has fixed mount 9, on fixed mount 9, be connected with draught line 10, the other end of draught line 10 is connected with piston 7 through right valve barrel, during original state, under the effect of draught line 10, spring I 8 is in compressive state, piston 7 is positioned at the blind end near valve body 3.Cavity between air-filled pore 4 ends of described baffle plate 5 and left valve barrel has a bleeder port 11, this bleeder port 11 is arranged on the sidewall of left valve barrel, and bleeder port 11 places are provided with sealing-plug 12, under original state, sealing plug 12 blocks bleeder port 11, and bleeder port 11 can not leaked gas.In the gas-filled cavity of described bag 1, be also equipped with and tighten up line 13, the one end of tightening up line 13 has annulus, the other end that tightens up line 13 stretches into trachea 2 and is connected with sealing-plug 12 through this annulus, the open end of tightening up line 13 penetrates in the gas-filled cavity of bag 1, around passing from the annulus of the other end after a circle.Described sealing-plug 12 is connected with spring II 15 by connecting line 14, spring II 15 is arranged on the outside of valve body 3, one end of spring II 15 is connected with sealing-plug 12, the other end of spring II 15 is fixedly connected with the outer wall of right valve barrel, and described spring II 15 outer wall that one end also has air-filled pore 4 one end by control line 16 and left valve barrel that is connected with connecting line 14 is connected.During original state, spring II 15 is in extended state under the pulling force effect of control line 16, and now, connecting line 14 does not also stress.
As shown in Figure 1, original state for specimen bag, specimen bag is put into intraperitoneal, now, in bag mouth gas-filled cavity due to bag 1, there is no gas, the bag mouth of bag 1 is in contraction state, when needs are opened bag mouth, with knife or operating scissors, draught line 10 is cut off, spring I 8 is owing to having lost the constraint of draught line 10, to baffle plate 5 directions, extend, drive piston 7 to move to baffle plate 5 directions, in this process, gas in valve body 1 cavity breaks through airtight thin film 6, and enter in the gas-filled cavity of bag mouth through trachea, the bag mouth of bag 1 is propped up completely, as shown in Figure 2, the specimen of getting is put into specimen bag, then with knife or operating scissors, control line 16 is cut off, now spring II 15 has lost the constraint of control line 16, blind end to valve body 1 shrinks, spring II 15 pulls sealing-plug 12 by connecting line 14, sealing-plug 12 is deviate from from bleeder port 11, gas in the gas-filled cavity of bag mouth is excluded, simultaneously, owing to tightening up line 13, be pulled, bag mouth is captive, just as the flour bag usually using, used time not, with rope, bag mouth is tied tight, as shown in Figure 3, after bag mouth shrinks, just can smoothly specimen bag be taken out to abdominal cavity, it is convenient and swift that whole specimen is taken out process.
