Problems solved by technology

[0004] However, due to the different parts of the patient that need biopsy sampling, such as the prostate, kidney, liver, spleen, breast and other tissues, the size of the suspected tumor that needs biopsy is usually different. Therefore, a biopsy with a suitable ejection stroke and puncture sampling length is required Needle surgery, the inner and outer needles of the above-mentioned biopsy needles have only one ejection stroke (generally 22mm). risk to other organs and tissues, resulting in failure or failure of the operation

Embodiment Construction

[0027] In the embodiment of the present invention, the structure of the puncture support is effectively optimized, which can not only reduce the size and cost, but also facilitate the flexible operation of the doctor and reduce the discomfort of the patient, which will be described in detail below.

[0028] When the disposable biopsy needle is used, the inner needle 1 is injected into the lesion first, and the inner needle 1 is provided with a sampling groove, and the sampling groove is full of lesions, and then the outer needle 2 is injected into the lesion, and the outer needle 2 quickly enters the lesion The lesion at the sampling groove is cut, so that the cut lesion is left in the sampling groove, and finally, the disposable biopsy needle is taken out, and the lesion sample taken out is tested and analyzed.

Abstract

The invention relates to the technical field of medical supplies, and in particular to a disposable biopsy needle with multiple ejection strokes. The disposable biopsy needle is provided with a gear adjusting component. The needle inserting depth of an inner needle and an outer needle can be adjusted by using a gear adjusting component, so that the disposable biopsy needle can meet requirements ofvarious biopsy operations and has higher universality. A doctor can perform more effective, accurate and appropriate puncture biopsy operations, and expected good focus tissues can be obtained undera condition that other tissues such as organs, nerves, blood vessels and the like are not damaged. Therefore, the disposable biopsy needle brings more reliable operations to patients, and operation efficiency and biopsy operation quality of the doctor are effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a disposable biopsy needle with multiple ejection strokes. Background technique [0002] Tissue tumor is a disease that seriously endangers human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Therefore, the nature of tissue tumors needs to be diagnosed as early as possible. Correct diagnosis requires the combination of clinical, imaging and pathological steps. Among them, pathological diagnosis plays a key role in the selection of treatment options, and biopsy is the main way to obtain tissue samples. [0003] Chinese patent CN109646061A discloses a biopsy needle with two excitation methods, including a first winding button 3 and a second winding button 13, the first winding button 3 is connected to the outer needle 2, and the second winding button 13 is connected to the inner needle 1, the two...
