Also comprise the connector being movably fixed to stylophore and outside of sleeve.
Further, described connector is openable taper, and its inwall is stepped, and bottom is provided with fixed card slot.
Further, described connector outer wall is provided with snap close.
Further, described connector inwall is elastomeric material.
Further, described needle tubing is provided with cross section near one end of needle point is trapezoidal sampling groove.
Further, described service aisle side is provided with scale strip.
Further, described sampling groove cross section height is 0.2-0.4mm, and two base angles are 30-50 degree.
Further, the degree of depth of described groove is 3-5mm, and width is 2-5mm, and movable passageway length is 10-15mm, and service aisle 43 length is 20-30mm, and rest area and behaviour area length are 1-3mm.
Further, described handle is provided with anti-skidding Vitex chinensis Mill. and antiskid particles.
This utility model compared with prior art has the following advantages:
1. be provided with fixture, in piercing process, sampling probe and tracheascope are integrated, and puncture needle can be made effectively to aspirate cutting back and forth in the tissue.
2. be provided with runner device, puncture needle puncture needle in suction sampling process effectively can be avoided to come off from pathological tissues, cause localised puncture again.
3. use dismountable connector, sampling probe can be made to be applicable to the tracheascope of different length.
4. needle point place adds sampling groove, can extract enough tissues and carry out pathologic finding, improves the positive rate that sampling probe tissue obtains.
This utility model structure is simple in sum; easy to operate; protection is provided for during sampling probe pumpback; be applicable to the tracheascope of different length, effective solve traditional sampling probe in use completely armrest sense control sampling probe there will be control inaccurate and capture affected area organize the very few problem cannot carrying out detecting.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.
As shown in Figure 1, a kind of puncture of the scope for tracheascope of this utility model sampling probe, comprise handle 1, nook closing member 12, syringe 11 and be fixed on the needle tubing 2 be connected on handle 1 and with syringe 11, on needle tubing 2, cover has internal diameter slightly larger than the stylophore 3 of needle tubing 2, needle tubing 2 is provided with cross section near one end of needle point 6 be trapezoidal sampling groove 7, sampling groove cross section height is 0.2mm, and two base angles are 30 degree.Stylophore 3 and handle 1 link are the sleeve pipe 4 being provided with groove and being connected with connector 8, and sleeve pipe is rigid plastics.One end of described handle 1 is can supply the concave inward structure of sleeve pipe 4 insertion and on inwall, be provided with the projection 5 that can embed groove, the position that the syringe 11 be connected with needle tubing 2 is used for fixing needle tubing 2 is connected at the other end of handle, nook closing member 12 is slightly longer than needle tubing 2 and is connected with the piston of syringe 11, and puncture is got tissue and terminated rear connection syringe 11 and nook closing member 12 to be pushed in needle tubing 2 the tissue release that can remain in and extract in needle tubing.Handle 1 is provided with anti-skidding Vitex chinensis Mill. 13 and antiskid particles 14.
