End face.At least two supporting walls 120 extend along preset direction.
In the present embodiment, support construction 12 includes three supporting walls 120.
To improve the effect of insertion and improving feeling of support by the end face that supporting walls 120 are located remotely from each other is in arcuation, supporting walls
120 end faces far from expansion matrix 11 are close to each other.
To further improve the effect of insertion and improving feeling of support by the side wall of supporting walls 120 is in arc line shaped, support
The distance between 120 two sidewalls of wall are gradually reduced along the direction far from expansion matrix 11, need to be with explaining, the present embodiment provides
A kind of shape of supporting walls 120: the one end of supporting walls 120 far from expansion matrix 11 is pointed in the diminishing lotus of profile, when
Expansion matrix 11 when being contracted to minimum diameter, mutually draw close by multiple supporting walls 120, multiple supporting walls 120 be placed in anus or
The one end in other natural ducts collectively forms the tip shape convenient for being placed in or being inserted into duct.
Further, expansion matrix 11 has outer ring end and inner ring end, and support construction 12 is located at close to outer ring end and limits
Supporting and space 60, specimen bag 13 are located in supporting and space 60 and are set to inner ring end.
It should be noted that the length along extending direction of supporting walls 120 is between 3-6cm, according to the need of operator
It asks, various sizes of supporting walls 120 may be selected.
Specimen bag 13 is removable installed on expander 10a and extends along preset direction, it should be noted that this implementation
That says in example is removably disposed, and refers to that specimen bag 13 can be separated with expander 10a, convenient for the aseptic process of expander 10a, tool
The dismountable structure in body ground, can be for card and connection, elasticity are arranged or dismountable structures such as magic bonding, specimen bag
13 one end far from expander 10a are the open end 130 for being connected to 13 internal cavities of specimen bag.
It should be noted that in the present embodiment, to enter in specimen bag 13 convenient for sample, open end 130 is in horn-like.
Silent hitch structure 14 is set to open end 130, and silent hitch structure 14 is configured to closing for control open end 130
It closes.
Specimen bag 13 has the Open attachment end relative to open end 130, and Open attachment end is connected to the inside of specimen bag 13
Cavity.Open attachment end is connect with inner ring end.
Silent hitch structure 14 is silent draught line, and one end of silent draught line is placed on open end 130, silent draught line
Through supporting and space 60, the other end of silent draught line is located at outside expander 10a.Specimen bag 13 be configured to by with it is default
Contrary direction pulls silent draught line to reduce the bore of open end 130, realizes the effect of closing open end 130.
It should be noted that the length of specimen bag 13 is between 20-35cm, by choosing various sizes of specimen bag 13,
Meets the needs of operation is different.
Inventor devises above-mentioned NOSE specimens from pri extractor 10, which can facilitate
Take out sample in the nature such as ground, effectively per anum or vagina duct.NOSE specimens from pri extractor 10 includes expander 10a and mark
This collector 10b.Expander 10a is structure as a whole with specimen trap 10b, expands anus or vagina by expander 10a
Then the diameter in equal natures duct is placed in specimen trap 10b to make a collection of specimens.Specifically, expander 10a includes expansion matrix
11 and support construction 12, wherein expansion matrix 11 is used to expand the support volume of support construction 12, that is, expansion anus etc. is natural
The diameter in duct such as is embedded in the natural duct such as anus, or is placed in anus at the surface in natural duct, and body surface support portion 20
It supports on body surface, the first connecting pin 111 due to expanding matrix 11 is configured to movably connect with its second connection end 112
It connects, and due to head and the tail both ends, that is, the connection of the first connecting pin 111 and second connection end 112, so that expansion matrix 11 is in volume
It is curved, by the relative positional relationship for changing the first connecting pin 111 and the connection of second connection end 112, thus it is possible to vary expansion matrix
11 outer diameter, and the relative positional relationship of the first connecting pin 111 and the connection of second connection end 112 is fixed, expansion base can be fixed
The outer diameter of body 11, that is, the diameter in the natural duct such as fixed anus.Support construction 12 is set to the end face of expansion matrix 11 and along pre-
Set direction extends, it should be noted that preset direction is expansion direction of the matrix 11 towards anus, and support construction 12 is for being placed in
The inner wall in the nature such as the anus or vagina duct and nature duct such as support anus or vagina.Specimen trap 10b includes sample
Bag 13 and silent hitch structure 14, specimen bag 13 are removable installed on expander 10a and extend along preset direction, work as expansion
After device 10a degrees of expansion is debugged, aseptic process specimen bag 13 by laparoscope from abdomen together with to external, and it is fixed
In on expander 10a, specimens from pri is placed in specimen bag 13, then by controlling silent hitch structure 14, so that specimen bag
13 open end 130 is closed, as shown in Fig. 2, sample is avoided to fall into enteron aisle, sample is caused to take out failure.Simultaneously because expander
The presence of 10a avoids sample and is extruded, ensure that tissue integrity.The NOSE specimens from pri extractor 10 can facilitate
