Detailed description of the invention
As shown in the figure: a kind of can automatic open and closed laparoscopic specimen bag, comprise bag 1 and trachea 2, the bag mouth of bag 1 is the double-decker be made up of outer and internal layer, gas-filled cavity is formed between skin and internal layer, 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 docked by left valve barrel and right valve barrel and forms, 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 being positioned at left valve barrel is provided with baffle plate 5, and the cavity of valve body 3 is divided into two parts by baffle plate 5.Described right valve barrel sidewall offers injecting hole, and injecting hole place is filled with the rubber stopper 17 for sealing, and injecting hole is used for injecting gas in the cavity of valve body 3, during injecting gas, rubber stopper 17 is extracted, then pull piston 7 to bleed, after inflation terminates, by rubber stopper 17 jam-pack.The center of described baffle plate 5 is provided with through hole, this through hole is provided with airtight thin film 6, be provided with piston 7 in the cavity of right valve barrel, piston 7 is connected by spring I 8 with between right valve barrel, and the outside of right valve barrel blind end also has fixed mount 9, fixed mount 9 is connected with draught line 10, the other end of draught line 10 is connected with piston 7, during original state, under the effect of draught line 10 through right valve barrel, spring I 8 is in compressive state, and piston 7 is positioned at the blind end near valve body 3.Cavity between air-filled pore 4 end 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 place is provided with sealing-plug 12, under original state, sealing plug 12 blocks bleeder port 11, and bleeder port 11 can not be leaked gas.Also be equipped with in the gas-filled cavity of described bag 1 and tighten up line 13, the one end of tightening up line 13 has annulus, the other end tightening up line 13 stretches into trachea 2 through this annulus and is connected with sealing-plug 12, the open end of tightening up line 13 penetrates in the gas-filled cavity of bag 1, passes from the annulus of the other end around 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, for the original state of specimen bag, specimen bag is put into intraperitoneal, now, owing to there is no gas in the bag mouth gas-filled cavity of bag 1, the bag mouth of bag 1 is in contraction state, when needs make bag mouth open, with knife or operating scissors, draught line 10 is cut off, spring I 8 is owing to losing the constraint of draught line 10, extend to baffle plate 5 direction, piston 7 is driven to move to baffle plate 5 direction, in this process, airtight thin film 6 breaks through by the gas in valve body 1 cavity, 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 loses 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, be pulled owing to tightening up line 13, bag mouth is captive, just as the flour bag usually used, the not used time, with rope, bag mouth is tied tight, as shown in Figure 3, after bag mouth shrinks, just smoothly specimen bag can be taken out abdominal cavity, it is convenient and swift that whole specimen takes out process.
