Embodiment Construction

[0016] Such as figure 1 As shown, an interventional cyst puncture needle provided by the present invention includes a needle shell 1, a needle core 2 is provided inside the needle shell 1, and a set of scale circles 1a are provided on the outside of the needle shell 1, and the characteristics are as follows:

[0017] a. The pinhole at the tip of the needle shell 1 is a bevel pinhole, which makes the puncture shell sharper; the scale circle 1a on the outside of the needle shell 1 is adjacent to each other at an interval of 1CM, and the scale circle 1a at 5CM from the front end is One thick line, the scale circle 1a at 5nCM is n thick lines, and the remaining scale circles 1a are all thin lines; the inner and outer walls of the front end of the needle shell 1 are about 5cm away from the needle tip, and the inner and outer walls are roughened with multiple interfaces, which can be thread-like, ring-like shape, frosted shape, etc.; the rear end of the needle shell 1 is provided wi...

Abstract

The invention relates to an interventional cyst puncture needle, comprising a needle shell (1), a needle core (2) is arranged inside the needle shell (1), and a set of scale circles (1a) are arranged on the outside of the needle shell (1) , characterized in that: the rear end of the needle housing (1) is matched with a group of detachable extension tubes (3), and the front end of the needle core (2) is provided with a group of hollow needles (4) distributed in bundles, the The hollow needles (4) distributed in bundles are also matched with the needle shell (1), each of the hollow needles (4) is connected with the needle core (2), and each of the hollow needles (4) A group of through holes (4a) are provided on the side walls. Advantages of the present invention: the puncture needle provided by the present invention is simple in structure, easy to use, and has good versatility. Various types of cyst puncture fluid and sclerotherapy needs.

Description

technical field [0001] The invention relates to a medical device, in particular to an interventional cyst puncture needle for clearing cysts and abscesses under the guidance of ultrasound. Background technique [0002] Interventional ultrasound technology has been widely used in clinical diagnosis and treatment due to its advantages of small trauma, good curative effect, and low cost. It has a good effect on the sclerotherapy of cysts in various organs in the human body. At present, the interventional puncture needles used under the guidance of ultrasound mainly include ordinary puncture needles (also known as PTC needles) and EV needles, but both have shortcomings. The main defects are: first, both are single-hole puncture needles, The shells use the single hole at the tip to suck the cystic fluid, without side holes: Second, the needle core of the former puncture needle is a solid needle, which cannot be used for drug injection; Third, the shell of the latter puncture need...
