Description

Netted foreign bodies in airway extractor

Technical field

This utility model relates to medical devices field, particularly to be a kind of netted foreign bodies in airway extractor.

Background technology

In current trachea-bronchial epithelial cell, foreign body main method has two kinds: one be dependent on by bronchoscopic biopsies pincers, damaged by rats pincers, alligator forceps clamp foreign body and take out. There is problem below in this method: 1. part foreign body smooth surface, it is difficult to clamp, such as more smooth bone foreign body or pearl. 2. part foreign body is easily caught broken, and uses clamp once to take out, and needs repeatedly clamp, consuming time very long. And it is caught broken rear section fine grained chippings and can enter less air flue. Such as Semen arachidis hypogaeae. 3. the part foreign body that the time is longer in air flue, can stimulate tracheal wall granulation hyperplasia to encase foreign body periphery surface, it is necessary to after cleaning periphery granulation, just can carry out clamp. 4. needed for part foreign body, operating time is long. Two is enter basket shape foreign body forceps by bronchoscope, and basket shape foreign body forceps entangles foreign body after opening and takes out. This method there is problems in that the space between 1. bigger foreign body and tracheal bronchus wall is too little, and basket shape foreign body forceps can not fully open, it is impossible to entangles foreign body. 2. the part foreign body that the time is longer in air flue, can stimulate tracheal wall granulation hyperplasia to encase foreign body periphery surface, it is necessary to after cleaning periphery granulation, it is possible to carry out entangling foreign body. 3. part foreign body extracts difficulty, it is necessary to longer operating time. 4. to extract operation easier big for part foreign body. 5. basket shape foreign body forceps is made up of four steel wires, and the gap between steel wire is relatively big, and fixing of foreign body is not good, is prone to come off using tracheascope to be pulled out by foreign body in the process of air flue.

For the actual case run in the recent period. Certain patient, during containing dark plum, is strayed into trachea, causes severe dyspnea, and anoxia is obvious. Owing to dark plum shape subcircular is similar to the shape of trachea, after entrance trachea, the space between dark plum and tracheal wall is too small, and basket shape foreign body forceps cannot open and entangle dark plum. And the appearance of dark plum is thicker and soft dark plum meat, when using alligator forceps and biopsy forceps clamp, because stress point is too little, it is impossible to whole dark plum is taken out, but it is only capable of pincers and takes a fritter dark plum meat. So repeatedly clamp repeatedly after, the gap expanded with tracheal wall after dark plum can be utilized to reduce, use basket shape foreign body forceps to extract dark plum, whole operation is consuming time very long, and seriously, thrill is very much for patient's anoxia.

In general, at present for foreign body limited through bronchoscope removing method in air flue, part foreign body possibly cannot be taken out through bronchoscope, and needs operative treatment.

Utility model content

The purpose of this utility model is the defect in order to overcome prior art, it is provided that a kind of netted foreign bodies in airway extractor, for the removing method that the taking-up offer of foreign bodies in airway is new.

This utility model solves its technical problem and be the technical scheme is that netted foreign bodies in airway extractor, include conduit, the head end of described conduit is provided with control pincers, the inside of described conduit is provided with and the several resiliency supported silks controlling clipper joint, the end of described resiliency supported silk encloses webbed foreign body net, and remainder is bundled into one.

Further, the described pincers that control are made up of handle and the movable block being located on handle, and described movable block connects resiliency supported silk.

Further, described resiliency supported silk is 2-4 root.

Further, described resiliency supported silk is elastic wire.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: part is taken out to the foreign bodies in airway of difficulty, foreign body net of the present utility model can be convenient to use and take out, shorten the operating time of foreign bodies in airway removal surgery, there is simple in construction, easy and simple to handle, operation easier is little, the advantage such as practical.

Detailed description of the invention

This utility model is further illustrated below in conjunction with the drawings and specific embodiments.

Embodiment 1

As shown in Fig. 1 and Fig. 2, Fig. 3, netted foreign bodies in airway extractor of the present utility model, include conduit 1, the head end of described conduit 1 is provided with control pincers 2, the inside of described conduit 1 is provided with and controls 3 resiliency supported silks 3 that pincers 2 are connected, described resiliency supported silk 3 adopts elastic wire, the end of described resiliency supported silk 3 encloses webbed foreign body net 31, remainder is bundled into one, the described pincers 2 that control are made up of handle 21 and the movable block 22 being located on handle 2, and described movable block 22 connects resiliency supported silk 3.

The present invention is used to take out foreign bodies in airway operating process as follows:

When being 1. in resting state, the foreign body net 31 of conduit 1 inner elastomeric supporting wire 3 end is in conduit 1 end intracavity. The control pincers 2 of the head end of conduit 1 can control foreign body net 31 by drawing handle 21 and stretch out outside conduit 1, or are recovered in conduit 1. When foreign body net 31 stretch out conduit 1 outer time, open according to the elasticity of foreign body net 31 self, be triangle during three resiliency supported silks 3, and foreign body net 31 head end of resiliency supported silk 3 far-end is opened.

2., when bronchoscope arrives above foreign body, conduit 1 is inserted by bronchoscope working channels. Conduit 1 is stretched into foreign body far-end by the gap of foreign body Yu airway walls.

3. controlling the handle 21 of pincers 2 by releasing conduit 1 head end, make the far-end of foreign body stretch out foreign body net 31, now, foreign body net 31 opens the far-end in foreign body.

4. by pulling out conduit 1, slowly exit resiliency supported silk 3, and fit through the position of operation bronchoscope adjustment resiliency supported silk 3 end foreign body net 31, when the foreign body net 31 of three resiliency supported silk 3 ends is about paperwrapped in foreign body in 120 degree respectively, the relative position of A/C 1 and foreign body, and slowly regain resiliency supported silk 3 by the handle 21 of pull catheter 1 head end control pincers 2, the foreign body net 31 that now resiliency supported silk 3 far-end has opened holds from the far-end of foreign body and fixes foreign body.

5. bronchoscope is exited by foreign body.
