Abstract

A ballonet specimen bag applied to collect and take out tissue organ specimens cut out during the course of a Video Assisted Thoracic Surgery (VATS) and a Video Laparoscopic Surgeries (VLS). A strip of spiral fashion ballonet is inlaid at the mouth and on the body of the specimen bag, whose one end is enclosed; the other end is communicated with a catheter, through which the air is pumped in to expand the specimen bag. By drawing some leading threads arranged in the ballonet and the catheter, the mouth of the bag can be tied up. Comparing with other present specimen bag in application, the utility model is characterized in convenience for use and low costs.

Description

The air bag specimen bag

Technical field

This utility model relates to a kind of air bag specimen bag, and this specimen bag is a kind of VATS that is used for, the collection and the withdrawing device of video-laparoscope excision specimen.

Background technology

Chinese patent CN2686549 discloses a kind of laparoscopic surgery specimen bag, need seal tubulose rope one end that is positioned at specimen bag bag mouth wire rope handling circle during use, injects air by the other end, to launch bag mouth.The amount of gas injection is difficult for grasping, and gas injection has been lacked, bag mouth Zhang Bukai; Gas injection is many, can make wire rope handling seal bonded tubulose rope around irising out mouthful again and separate with it, makes bag mouth transfer rounding state to.Need roll up when specimen bag is inserted the abdominal cavity to cylindric, after bag mouth launches, or when bag mouth and bag at an angle the time, pocket portion can attach mutually, draw close, and influences inserting of specimen.Simultaneously, the gas in its tubulose rope also influences the gathering of bag mouth.The main deficiency of this specimen bag is can easily not launch and draw in bag mouth, can't effectively launch bag.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes specimen bag and can easily not launch and draw in bag mouth, can't effectively launch the deficiency of bag.

For solving the problems of the technologies described above, the technical scheme that is adopted is: inlay an air bag of shape distribution in the shape of a spiral on specimen bag bag mouth and bag, the one end is a cecum, and the other end is connected with a conduit.Not during injecting gas, airbag wall is drawn close mutually in the air bag, and blister cavities disappears; Behind the injecting gas, air bag is the shape cylinder in the shape of a spiral in the air bag.By the tension force of its generation, promptly deployable bag mouth and bag.Be arranged at seal wire in gasbag notch portion and conduit, the control part front end by tractive, can draw bag mouth in.

The beneficial effects of the utility model are to provide a kind of and can launch bag mouth and bag easily, and can draw breast, the laparoscopic surgery specimen bag of bag mouth easily in.

The specific embodiment

As shown in Figure 2, the air bag specimen bag is made up of specimen bag (8), seal wire (3), conduit (2) and coupled control part front end (4) and control part rear end (5).Specimen bag (8) is made by the nylon of polyurethane or outsourcing polyurethane, wherein the zone of nipper grip zone (7) clamping when catching specimen bag for nipper.The air bag (1) that the shape of inlaying on specimen bag bag mouth and the bag in the shape of a spiral distributes adopts the nylon of polyurethane or outsourcing polyurethane to make.One end of air bag (1) is a cecum, and the other end is connected with a conduit (2), shape cylinder in the shape of a spiral after air bag (1) inflation.Air bag (1) is embedded in the part of bag mouth and conduit (2), the control part front end (4), and a seal wire of being made by nylon (3) is arranged.These seal wire (3) one ends are attached to seal wire attachment point (6), and the other end is attached to control part rear end (5).After control part rear end (5) turned on from control part front end (4), can bag mouth be drawn in tractive seal wire (3) by control part rear end (5).Conduit (2) adopts polyethylene to make, and is the passage of gas turnover, and itself is not expanded or shrink with inflation or venting.There is seal wire (3) to pass through in the conduit (2).Make by polyethylene control part front end (4) and control part rear end (5).There is a unidirectional flap valve (9) control part rear end (5), connects syringe, can be in air bag (1) injecting gas, remove syringe after, gas can not spill.Control part rear end (5) can be turned on from control part front end (4), and control part rear end (5) with after control part front end (4) separates, gas can be located to spill by control part front end (4).

Using method of the present utility model is: after twisting in specimen bag (8) on the conduit (2), be resting state, as shown in Figure 1.With specimen bag (8) among nipper clamping Fig. 1, it is sent into body cavity (breast, abdominal cavity), the part of conduit (2) and control part front end (4), control part rear end (5) are stayed outside the body cavity.Nipper is decontroled specimen bag (8), locates injecting gas with syringe by unidirectional flap valve (9), bag mouth and bag is launched, as shown in Figure 2.With nipper clamping nipper grip zone (7), catch specimen bag.In specimen bag, insert specimen by another nipper.Control part rear end (5) are turned on from control part front end (4), emit gas, or with syringe from unidirectional flap valve (9) gas bleeding.By control part rear end (5) tractive seal wire (3), draw bag mouth in, as shown in Figure 5.By nipper or tractive conduit (2), specimen bag (8) is pulled out through incision.

Claims

A kind of air bag specimen bag is characterized in that: inlay an air bag (1) of shape distribution in the shape of a spiral on specimen bag (8) bag mouth and bag, an end of air bag (1) is a cecum, and the other end is connected with a conduit (2).
