Abstract

The utility model relates to a disposable sample taking bag, comprising an outer sleeve, a handle, an operating rod, a connecting rod, elastomers, a bag mouth, a soft band, and a bag body, the handle is fixed on a tail end of the outer sleeve, the operating rod is sleeved into the outer sleeve, and the connecting rod and a front end of the operating rod are fixed; the two elastomers are symmetrically snapped into the connecting rod and fixed, and sleeved into the end of the bag mouth; the soft band passes through the bag mouth and passes through a gap between the outer sleeve and the operating rod; and the bag body and the bag mouth are fixed to be a whole. The disposable sample taking bag is reasonable in structural design, can effectively take operation residues out of a body without dropping easily, and the operation efficiency is improved.

Description

Disposable specimen fetching bag

Technical field

This utility model relates to a kind of disposable specimen fetching bag, is exclusively used in taking out after the lesion resection in human body externally, belongs to technical field of medical instruments.

Background technology

In human body in Wicresoft's laparoscopic procedures, once find focus (as tumor, cyst, calculus etc.) at people's in-vivo tissue organ pipe, need excision, focus after excision need to be taken out outside human body, prior art is to carry out gripping with general nipper, its defect is: nipper captures and easily to cause the focus after excision to stay in the body, and particularly calculus (as multiple cholesteric calculus etc.) easily stays in the body, and can not meet desirable surgical effect.

Utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and a kind of reasonable in design is provided, and can effectively the residue of performing the operation in human body be taken out to external disposable specimen fetching bag.

This utility model solves the problems of the technologies described above adopted technical scheme: a kind of disposable specimen fetching bag, it is characterized in that: it comprises trocar sheath, handle, action bars, connecting rod, elastomer, bag mouth, soft band, bag, described handle is fixed on the end of trocar sheath, action bars is inserted in trocar sheath, and the front end of connecting rod and action bars is fixed; The symmetrical Snap joint bar of two described elastomers is fixed, and two elastomers are inserted in respectively one end of bag mouth; Described soft band is through bag mouth, and passes from the gap of trocar sheath and action bars; Described bag and bag mouth are fixed into one.

The material of bag described in the utility model is medical high polymer film.

This utility model compared with prior art, has following positive effect: reasonable in design, can be effectively that the taking-up of operation residue is external, and be difficult for dropping, improved operation efficiency.

The specific embodiment

Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail.

Embodiment:

Referring to Fig. 1～Fig. 3, Fig. 9, the present embodiment comprises trocar sheath 1, handle 2, action bars 3, connecting rod 8, elastomer 6, bag mouth 7, is softly with 4, bag 5, described handle 2 is fixed on the end of trocar sheath 1, and action bars 3 is inserted in trocar sheath 1, and connecting rod 8 is fixed with the front end of action bars 3; The symmetrical Snap joint bar 8 of two described elastomers 6 is fixing, and two elastomers 6 are inserted in respectively one end of bag mouth 7; Described be softly with 4 through bag mouth 7, and pass from the gap 9 of trocar sheath 1 and action bars 3; Described bag 5 is fixed into one with bag mouth 7.

During use, referring to Fig. 1, first bag 5 is wrapped on elastomer 6, fills in trocar sheath 1.Referring to Fig. 2～Fig. 3, promote action bars 3, bag 5 overflows to trocar sheath 1, and under the effect of elastomer 6, bag mouth 7 struts, and forms and gets thing bag.

In the present embodiment, the material of bag 5 is medical high polymer film, and bag 5 is thin, has very high intensity.

In the present embodiment, elastomer 6 adopts Nitinol to pass through high-temperature shaping several times, forms the automatic deploying device of bag mouth 7 with memory function, at bag 5, from trocar sheath 1 stretches out, realizes and automatically opens bag mouth 7, and assurance bag mouth 7 is opened effect, facilitates operation technique.

In the present embodiment, softly with 4 technology, install, make both expansibles of bag mouth 7, pull and be softly with 4, bag mouth 7 can close again, guarantees that foreign body and specimen can not overflow and drop in the interior taking-up process of bag 5 in operation.

The disposable use of the present embodiment, avoids cross infection in art, improves operation efficiency.

During operation, referring to Fig. 4, first bag 5 is inserted in trocar sheath 1, and this utility model is inserted in to perforator 10, perforator 10 is inserted in needs to use position of the present utility model in human body.

Referring to Fig. 5, promote action bars 3, bag 5 is overflowed outside trocar sheath 1, at the effect lower bag body 5 of elastomer 6, strut, foreign body and the specimen of in operation, cutting are displayed in bag 5.

Referring to Fig. 6, pull back action bars 3, action bars 3 and elastomer 6 are pulled out.

Referring to Fig. 7, pull back handle 2, handle 2 and trocar sheath 1 are pulled out.

Referring to Fig. 8, be stakely backward with 4, be softly with 4 bag mouth 7 is bound, and the bag after closing 5 and perforator 10 are taken out to human body stomach walls, guarantee that foreign body and specimen can not overflow and drop in bag.

In addition, it should be noted that, the specific embodiment described in this description, as long as the undeclared concrete shape of its part and size, this part can be any shape and size that adapt with its structure; Meanwhile, the title that part is got also can be different.All equivalence or simple change of doing according to described structure, feature and the principle of this utility model patent design, are included in the protection domain of this utility model patent.
