Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a puncture sampler for medical oncology, which solves the problem that the piston plate may move greatly during the manual operation of the existing puncture sampling device, which may cause pain to the patient or affect sample sampling. At the same time, the process of puncture sampling is inconvenient to take out the internal sample after the real sampling is completed.

Embodiment Construction

[0022] The technical solution of this patent will be described in further detail below in conjunction with specific embodiments.

[0023] Such as Figure 1-3 As shown, the present invention provides a technical solution: a puncture sampler for medical oncology, comprising a barrel 1, a needle holder 2 is provided on the left side of the barrel 1, and a puncture sampling needle 3 is provided in the needle holder 2. The upper surface of the body 1 is provided with a connecting pipe 4, and the positive pressure bag 6 can be easily removed and replaced by the connecting piece 5. The connecting pipe 4 communicates with the positive pressure bag 6 through the connecting piece 5. By setting the positive pressure bag 6, The high-pressure gas in the positive pressure bag 6 can be used to discharge the tissue in the puncture sampling needle 3 to avoid the direct extrusion of the piston plate 13 that may cause tissue deterioration, and to ensure the smooth and simple removal process of the ...

Abstract

The invention discloses a puncture sampler for medical oncology, which belongs to the technical field of medical treatment, the puncture sampler comprises a cylinder body, a needle seat is arranged onthe left side surface of the cylinder body, a puncture sampling needle is arranged in the needle seat, a connecting pipe is arranged on the upper surface of the cylinder body, the connecting pipe iscommunicated with a positive pressure bag through a connecting piece, and a bearing is arranged on the right side surface of the cylinder body. The invention discloses the puncture sampler for medicaloncology, the positive pressure bag, an air valve, the cylinder body, a piston plate, the puncture sampling needle, a threaded cylinder, a threaded column and a rotating rod are matched with one another; the piston plate moves to the right side of the connecting pipe; by means of the sampler, the situation that the piston plate moves by a large margin during misoperation can be prevented, the sampling process is conducted smoothly to a certain extent, and meanwhile the process that the tissue is taken out of the puncture sampling needle is convenient.

Description

Technical field [0001] The invention belongs to the field of medical technology, and is specifically a puncture sampler for oncology. Background technique [0002] At present, in the clinical tumor inspection process, puncture is used to sample cells and tissue specimens and then perform pathological examinations, which is an important means for diagnosing the nature of tumors. [0003] However, most of the existing puncture and sampling devices are directly driven by the medical staff to move the piston plate, which may cause a large movement of the piston plate during the sample extraction process due to uneven force, which may cause unnecessary pain to the patient and affect the sample extraction. The process progresses smoothly, and it is inconvenient to take out the sample after sampling in the puncture sampling needle. Therefore, a puncture sampler for oncology is needed. Summary of the invention [0004] (1) Technical problems solved [0005] In order to overcome the above-me...
