Description

Diagnosis and treatment needle for cyst

Technical Field

The utility model relates to the technical field of surgical instruments, in particular to a diagnosis and treatment needle for cysts.

Background

Cysts are benign sacs growing on the surface of the human body or in a certain organ of the body, and the contents are liquid. Abscess is a localized accumulation of pus in tissues, organs or body cavities during acute infection due to necrosis and liquefaction of diseased tissues. Hematoma is the rupture of blood vessels due to various external forces, and the overflowed blood separates peripheral tissues to form cavities filled with blood.

In clinical work, when cysts, abscesses and hematoma liquid masses are treated, puncture suction needs to be performed on the liquid-containing masses through diagnosis and treatment, however, the existing diagnosis and treatment needle has some defects, for example, in the process of cyst sclerosis treatment, the needle point of the PTC needle is positioned in the cyst, and the cyst wall is easy to puncture to cause bleeding. In addition, the needle tip part is only provided with one open pore without a side hole, so that the needle tip is easy to be blocked, and although a drainage tube with the side hole is sometimes used in the cyst hardening process, the drainage tube is soft and inconvenient to operate and adjust the position of the needle. In conclusion, the existing diagnosis and treatment needle or tube brings certain risks and inconvenience to the operation of cyst sclerosis treatment.
