Description
Technical field
This utility model relates to a kind of lung tumors operation sampler, especially a kind of biopsy needle structure for lung tumors.
Background technology
Aspiration biopsy is a kind of important way of lung tumors being carried out to pathological diagnosis.Aspiration biopsy is completed by biopsy needle, and biopsy needle punctures at lesions position, and is taken out by the tissue samples of lesions position.Chinese utility model patent CN204364028U disclose a kind of can the mechanism on marked tumor border on biopsy needle, the object that tumor-localizing is followed the trail of can be reached by placing label.But, placement location when placing label of the puncture needle of this structure and sample position distant, and sample tissue there will be more coming off in puncture needle removal process, in order to obtain enough samples, just sampling amount must be strengthened, and the tissue samples come off also can affect the position of label further.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of biopsy needle structure for lung tumors, can solve the deficiencies in the prior art, improves the positional accuracy of label, reduces the additional injuries for lesions position.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of biopsy needle structure for lung tumors, comprise needle tubing, slide in needle tubing and be provided with syringe needle, be provided with in needle tubing and control the flexible ejection system of syringe needle, the top of described syringe needle is provided with sampling cavity, the both sides of sampling cavity are respectively provided with a chute, slide in chute and be provided with elastic baffle, two elastic baffles contact with each other in the import department of sampling cavity, the top of sampling cavity end is provided with through hole, slide in through hole and be provided with support bar, the top of support bar is provided with rubber sleeve, label is connected with in rubber sleeve, the top of elastic baffle is provided with lobe, spring body is connected with between lobe and the inwall of needle tubing, when syringe needle is released needle tubing by ejection system, lobe and rubber sleeve come in contact extruding.
As preferably, the bottom of described sampling cavity is provided with arc groove, and the inner side at sampling cavity exit place is provided with pawl portion.
As preferably, the bottom of described rubber sleeve is provided with rigid clasp, and label is designed to truncated cone-shaped, and one end that label diameter is larger is positioned at the top of rubber sleeve.
The beneficial effect adopting technique scheme to bring is: this utility model on the basis of existing technology, changes the installation site of label on puncture needle, thus makes label can place the position nearer with distance sampling position.Elastic baffle can avoid the tissue outside focus to enter in sampling cavity at the initial stage of puncture, when syringe needle stretches out close to outermost, under the pull effect of spring body, elastic baffle is separated to both sides, at this moment under the effect of syringe needle puncture, the tissue samples of lesions position enters sampling cavity, and support bar upwards holds up by the tissue samples entering sampling cavity.Meanwhile, along with the stretching of elastic baffle, the lobe at its top is close to each other, produces extruding, extruded by label, label is placed near sample position rubber sleeve.When syringe needle reclaims, elastic baffle resets, and is again closed by sampling cavity, prevents tissue samples from leaking.The arc groove of the bottom of sampling cavity can avoid tissue samples directly to extrude the side of support bar, thus avoids the jammed problem of support bar.The stability of tissue samples in sampling cavity can improve in pawl portion on sampling cavity, reduces tissue samples and leaks.Rigid clasp serves the effect of unidirectional cutoff, avoids label to move downward, and the shape of label is convenient to lobe and is carried out extruding extrapolation to it, can ensure that label releases rubber sleeve smoothly.
