Abstract

The present invention relates to the field of medical devices and particularly to a multi-point and multi-depth puncture sampling device. The provided puncture sampling device comprises a needle bodybase, the needle body base comprises a first air cavity and a first connector, the first connector communicates with a first air cavity, a puncture needle base surface is arranged on the needle body base, a plurality of puncture needles are arranged on the puncture needle base surface, a needle cavity of each puncture needle communicates with the first air cavity, and at least a part of the puncture needles are different in length. The provided puncture sampling device can puncture and extract more tissue cells on different planes and multiple parts at the same time and provides richer sampletissues for definite diagnosis of subsequent cytological pathology.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a multi-point and multi-depth puncture sampling device. Background technique [0002] In dermatology, there are many diseases that cannot be directly diagnosed clinically, and skin biopsy is required to confirm the diagnosis or assist the diagnosis. In particular, malignant skin tumors have various manifestations, and pathological diagnosis is the only gold standard. However, when the wound surface is large such as diabetic ulcer or malignant tumor ulceration, the traditional diagnosis often requires multi-point sampling, resulting in large damage, low efficiency, difficult to suture the wound, and easy secondary infection. Clinical needs are more convenient, less invasive, easy to carry out and easy to accept for patients, which can provide deeper and more reliable histological information than dermoscopy without the trouble and trauma of biopsy. Acupuncture aspiration cytol...
