elastic cell harvester

Abstract

An elastic cell collector comprises a main device, a moving device and an elastic device; the moving device is used for pumping and storing cells; the moving device is disposed inside the main device; the elastic device is disposed between the main device and the moving device and provides power for natural elasticity and pumping of the moving device, assisting in generating negative pressure in the moving device so that the cells are collected to the moving device through a collecting port; the main device provides a force supporting point for the elastic device. The main device comprises an outer cylinder (2) and a needle base (1) disposed on the outer cylinder; the moving device comprises an inner cylinder (3), an outer needle plug (4), an inner needle plug (5) and a handle (6). The invention retains the advantages in single operation and also avoids limitation in the single operation; the implementation of an accurate puncture technique and the acquisition of diagnostically valuable cytological specimens are facilitated, and occurrence of various dangers is avoided to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and relates to a clinical collection device for fine-needle aspiration cytology examination, especially a cell collection device. Background technique [0002] Fine needle aspiration cytology (FNAC) is a cell diagnosis that uses fine needle aspiration to absorb cells and other components in the lesion to make a smear, and observe the morphological changes and interstitial changes of tumor and non-tumor cells study. During the implementation process, according to the texture and nature of the tumor, a disposable syringe with a size of about 10 cm can be used for puncture at present. Absorb palpable swollen lesions through the patient's body surface, or perform needle aspiration on deep organ lesions guided by X-ray, B-ultrasound, CT and radionuclide scanning, and absorb tiny tissue components (including cells, interstitium or other accompanying tissues) Objects) for cell morp...

AI Technical Summary

Problems solved by technology

The disadvantage is that the operator has to complete the extensive action of pulling back the needle plug to generate negative pressure, and the fine action of repeatedly sucking the puncture needle into the nodule several times, which is inherently contradictory. , requires the operator to have strong physical coordination, but most clinicians are obviously difficult to master, which will easily lead to various dangers and reduce the success rate and accuracy of biopsy

Therefore, single-person operation is the most conducive to achieving perfect and accurate puncture techniques and obtaining cytology specimens with diagnostic value, and avoiding various risks to the greatest extent. However, as far as the current equipment is concerned, it is only suitable for physical coordination. Very strong clinicians, because most clinicians are difficult to master the technical essentials, so it is difficult to benefit the public
