Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and 2, the utility model discloses a lung cancer tumor sampling device, which comprises a sampling injector and a guide structure. The guide structure is mainly used for guiding the sampling injector. The sampling syringe in this scheme is similar to the disposable syringe needle in the prior art, and comprises a syringe barrel 2 and a needle head. A push rod 1 is arranged in the needle cylinder 2, a piston 3 is fixed on the push rod 1, and the needle head comprises a needle seat 4 and a sampling needle 5.

And the guide structure comprises a guide outer cylinder 6, wherein the inner wall of the guide outer cylinder 6 is in sliding fit with the outer wall of the needle cylinder 2. The coaxial fixed mounting of one end of direction urceolus 6 has sucking disc 9, the middle part coaxial arrangement of sucking disc 9 has stainless steel hollow needle tubing 8, stainless steel hollow needle tubing 8 with direction urceolus 6 is fixed, and the one end that direction urceolus 6 was kept away from to stainless steel hollow needle tubing 8 sets up to the pinpoint form. And the inner side wall of the stainless steel hollow needle tube 8 is in sliding fit with the outer side wall of the sampling needle 5, and the sampling needle 5 can penetrate through the stainless steel hollow needle tube 8. One end of the stainless steel hollow needle tube 8 far away from the guide outer cylinder 6 extends to the outside of the suction cup 9, so that the stainless steel hollow needle tube 8 can be penetrated into the skin tissue 11 of the human body.

The cover is equipped with spacing collar 10 on the cylinder 2, and it has the silica gel layer still to optimize the parcel on the spacing collar 10 to do benefit to rotatory spacing collar 10, prevent that the hand from skidding. The limiting ring 10 is coaxially in threaded connection with the needle cylinder 2, and scales are axially carved on the outer side wall of the needle cylinder 2. The guide outer cylinder 6 can be a transparent glass tube or a transparent hard plastic tube, so that the working state of the sampling injector can be observed conveniently. And the internal diameter of the hollow needle tube 8 of stainless steel is 1mm to 3mm bigger than the external diameter of the sampling needle 5, so that the sampling needle 5 can smoothly pass through the hollow needle tube 8 of stainless steel, and the deviation value of the sampling needle 5 deviating from the hollow needle tube 8 of stainless steel is smaller.

The sampling device in the scheme is implemented according to the following principles: firstly, a part to be sampled is determined on the skin surface of a human body, and then the stainless steel hollow needle tube 8 is penetrated into the skin tissue 11 of the human body. As shown in FIG. 2, after the stainless steel hollow needle tube 8 penetrates the skin tissue 11 of the human body, the suction cup 9 is gradually compressed and is adsorbed to the skin tissue 11 of the human body. The barrel 2 of the sampling syringe is then pushed down gradually along the guide outer cylinder 6. The limit ring 10 is rotated and the scales on the needle cylinder 2 are read to limit the relative movement distance between the needle cylinder 2 and the guide outer cylinder 6, so as to control the maximum depth of the sampling needle 5 penetrating into the skin tissue 11 of the human body.

When the sampling needle 5 penetrates into the skin tissue 11 of the human body downwards, the sampling needle 5 firstly penetrates through the stainless steel hollow needle tube 8 and then penetrates downwards until the required depth is reached, and then the push rod 1 is pulled upwards to finish sampling. After sampling, the needle cylinder 2 is taken out from the guide outer cylinder 6, and then the guide structure is taken down from the skin tissue 11 of the human body, so that the whole sampling process is completed.

In the process, the needle cylinder 2 is guided by the guide outer cylinder 6, so that the problem of penetration angle deviation caused by arm shaking of an operator is avoided; the piercing direction of the sampling needle 5 is further guided by the stainless steel hollow needle tube 8, and the problem of piercing deviation caused by the influence of other tissues of a human body due to the slender sampling needle 5 is avoided. Therefore, the operation is less disturbed externally, the puncture is accurate, and the depth of the puncture is controlled. Avoid puncture dislocation, puncture depth degree too dark, effectively solved present sample syringe and accomplished the uncontrolled and thorn of puncture in-process degree of depth problem partially.

During specific operation, the silica gel sleeve 7 can be sleeved on the guide outer cylinder 6, so that the hands of an operator can slip conveniently, and the stainless steel hollow needle tube 8 can penetrate into skin tissues 11 of a human body more smoothly.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
