Abstract

A puncture needle for treatment of visceral cyst sclerosis pertains to the technical field of the medical devices, which is mainly used in the intervention therapy of the cyst. The utility model is provided with a trocar needle and a core needle which are connected by a loop, the needle tube of the trocar needle is a flexible plastic tube, when in use of the puncture needle to carry out the CT-guided intervention therapy of the visceral cyst, the needle handle and the needle tube of the core needle are punctured into the cyst cavity at the same time, then the core needle is pulled out, the cyst liquid and the injected medicine are extracted by the trocar needle; because the needle tube of the trocar needle is a flexible plastic tube, the utility model can not damage the cyst wall when changing the extraction direction and the depth, in addition, the extraction of the cyst liquid is complete, the operation is easy, and the utility model can reduce the additional injuries of the patients.

Description

Internal organs cyst sclerotherapy puncture needle

Technical field

This utility model belongs to technical field of medical instruments, specifically relates to a kind of cyst interventional therapy puncture needle.

Background technology

Internal organs cysts such as liver, kidney, ovary are a kind of common benign disease, use equipment guiding such as B ultrasonic, CT and carry out the Therapeutic Method that interventional therapy is present the best; The existing puncture needle that uses generally is an inclined-plane metal puncture pin, during treatment, for capsule liquid being taken out to the greatest extent, usually need conversion syringe needle direction and position, after particularly part capsule liquid was extracted, blister cavities subsided, moving of needle point, often cause needle point to wear out cyst wall, cause unnecessary misery, also affect the treatment to patient.

Summary of the invention

The purpose of this utility model provides a kind of capsule liquid all can being taken out to the greatest extent, and can not damage the puncture needle of cyst wall.

The technical scheme that its technical problem that solves this utility model adopts is: comprise trocar and core pin that kink connects, the needle tubing of trocar is flexible software pipe, and the needle handle of core pin is located in the needle stand, and needle body passes needle tubing, needle point stretches out outside the needle tubing, and needle point is taper or inclined plane shape.

The beneficial effects of the utility model are: it is provided with trocar and the core pin that kink connects, during puncture, the needle handle of core pin and needle tubing penetrate blister cavities simultaneously, and when needle point arrived certain position, the core pin was extracted, extract capsule liquid and inject medicine by trocar, because the trocar needle tubing is flexible software pipe, the conversion pumping direction and the degree of depth can not damaged cyst wall, not only capsule liquid extracts thoroughly, and has reduced the additional injuries to patient.
