The present invention's will solve the problems, such as realize by following scheme：
A kind of scope for airway wall punctures sampling probe, it is characterised in that：Including handle, nook closing member, syringe and fixation
The needle tubing being connected on handle and with syringe, the stylophore that internal diameter is slightly larger than needle tubing, the stylophore and hand are cased with the needle tubing
Handle connection end is provided with sleeve pipe, and described sleeve pipe sets surface and is provided with groove, and one end of the handle is the indent knot for being available for sleeve pipe to insert
Structure, the projection that the inwall of the concave inward structure is provided with depth of groove and width matches, the groove are two, include putting
Area is put, the rest area is connected by " L " type movable passageway with service aisle, and activity is provided with the side of the movable passageway
Area;
Also include being movably fixed to stylophore and the connector of outside of sleeve.
Further, the connector is openable taper, and its inwall is stepped, and bottom is provided with fixing card
Groove.
Further, the connector outer wall is provided with lock.
Further, the connector inwall is elastomeric material.
Further, the needle tubing is trapezoidal sampling groove provided with cross section close to one end of needle point.
Further, the service aisle side is provided with scale strip.
Further, the sampling groove cross section is highly 0.2-0.4mm, and two base angles are 30-50 degree.
Further, the depth of the groove is 3-5mm, and width is 2-5mm, and movable passageway length is 10-15mm,
The length of service aisle 43 is 20-30mm, and rest area and activity section length are 1-3mm.
Further, the handle is provided with the anti-skidding twigs of the chaste tree and antiskid particles.
The present invention has advantages below compared with prior art：
1. being provided with fixing device, sampling probe and airway wall are integrated in puncture process, puncture needle can be made effectively to exist
Suction cutting back and forth in tissue.
2. runner device is provided with, it is possible to prevente effectively from puncture needle puncture needle in sampling process is aspirated takes off from pathological tissues
Fall, cause to reposition puncture.
3. using dismountable connector, sampling probe can be made to be applied to the airway wall of different length.
4. adding sampling groove at needle point, enough tissues can be extracted and carry out pathologic finding, improve sampling probe tissue
The positive rate of acquisition.
It is of the invention simple in construction in summary, it is easy to operate, to provide protection during sampling probe pumpback, suitable for different length
Airway wall, effectively solving traditional sampling probe, complete armrest sensing control sampling probe occurs that control is inaccurate and grabs when in use
Take tissue very few the problem of can not being detected of affected area.

Embodiment
The invention will be further elaborated with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of scope for airway wall of the present invention punctures sampling probe, including handle 1, nook closing member 12, injection
Device 11 and the needle tubing 2 for being fixed on handle 1 and being connected with syringe 11, the stylophore that internal diameter is slightly larger than needle tubing 2 is cased with needle tubing 2
3, needle tubing 2 is trapezoidal sampling groove 7 provided with cross section close to one end of needle point 6, and sampling groove cross section is highly 0.2mm,
Two base angles are 30 degree.Stylophore 3 is the sleeve pipe 4 being connected provided with groove and with connector 8 with the connection end of handle 1, and sleeve pipe is hard
Plastics.One end of the handle 1 is the concave inward structure for being available for sleeve pipe 4 to insert and is provided with inwall and can be embedded in the projection 5 of groove,
It is used for fixing the position of needle tubing 2 in the syringe 11 that the other end connection of handle is connected with needle tubing 2, nook closing member 12 is slightly longer than needle tubing 2
And be connected with the piston of syringe 11, puncture takes tissue to connect syringe 11 after terminating and nook closing member 12 is pushed into needle tubing 2 and can be incited somebody to action
The tissue for remaining in extraction in needle tubing is released.Handle 1 is provided with the anti-skidding twigs of the chaste tree 13 and antiskid particles 14.
As shown in Fig. 2 relative on sleeve pipe be provided with two, when not using, projection 5 exists in rest area 41, now needle point 6
The termination of stylophore 3 is concordant；It is connected to a fixed during use with airway wall, airway wall, which enters lesions position, is, projection 5 is from rest area 41
It is moved to by " L " type movable passageway 42 in behaviour area 44, now needle point beyond stylophore and fully penetrates lesion；Again by projection
5 are moved in service aisle 43, and sampling probe can continue puncture and enter lesion in service aisle, be set in service aisle side
There is a controllable depth for being pierced into lesion of scale strip 45, projection 5 is blocked in one end of service aisle 43 during pumpback, and needle point is not during pumpback
It can completely take in stylophore 3, ensure that puncturing sampling probe will not come off from pathological tissues, the depth of its further groove is 3mm,
Width is 2mm, and the length of movable passageway 42 is 10mm, and the length of service aisle 43 is 20mm, rest area 41 and the length of behaviour area 44
It is 2mm.
As shown in Figure 3, Figure 4, the connector 8 is the openable taper being connected through the hinge, and its inwall is rank
Scalariform, bottom are provided with fixed card slot 9.The outer wall of connector 8 is provided with lock 10, and the inside of connector 8 is elastomeric material
It is made, the stepwise interior wall is slightly less than stylophore and sleeve pipe, can clamp stylophore and sleeve pipe 4, and dismountable connector 8 is adjustable
Sampling probe and the distance of scope front end, can effectively be punctured into tissue.The airway wall of different length is can apply in addition.
In use, the annular protrusion 81 that connector 8 is snapped into stylophore 3 and the upper end of upper connector 8 is stuck in the work of airway wall
Make on passage, airway wall is sent into human body, taken out affected area tissue by sampling groove 7 and needle point 6, needle point can not during pumpback
Completely in income stylophore 3, it ensure that puncturing sampling probe will not come off from pathological tissues.
