In order to solve the technical problem, the utility model discloses a technical scheme is:

the utility model provides a binary channels lavage needle utensil, includes that the front end is the semi-solid needle tubing of closed blunt end, be equipped with lavage passageway and drainage channel that sets up side by side and mutual isolation in the needle tubing, the lateral wall that the needle tubing is close to the front end is equipped with the through-hole that communicates with lavage passageway and drainage channel respectively, the tail end of needle tubing be equipped with respectively with inlet and the liquid outlet of lavage passageway and drainage channel intercommunication.

The needle tube of the double-channel lavage needle tool is semi-solid, has certain strength, can realize blunt stripping of the bonding tissue in the joint cavity, does not damage the tissue in the joint, and fully releases inflammatory substances in the joint cavity. Moreover, this binary channels lavage needle utensil can realize lavage, drainage on one side, carries out lavage and drainage simultaneously promptly, improves treatment effeciency, guarantees that the articular intracavity hydrops is fully washed totally.

Preferably, the ratio of the total volume of the lavage channel and the drainage channel to the volume of the needle tube is (1-2) to 3.

More preferably, the ratio of the total volume of the irrigation passage and the drainage passage to the volume of the needle cannula is 1: 2.

Preferably, the irrigation channel and the drainage channel are of the same shape and volume.

Preferably, the diameter of the needle tube is 2.4-3.0 mm.

Preferably, the length of the area of the side wall of the needle tube provided with the through hole is 1.0-1.5 cm.

Preferably, the double-channel lavage needle is Y-shaped.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a binary channels lavage needle utensil's needle tubing is semi-solid, has certain intensity, can realize that the blunt nature peels off the interior glutinous tissue of joint chamber, does not harm the interior tissue of joint, makes joint chamber inflammation material fully release. Moreover, this binary channels lavage needle utensil can realize lavage, drainage on one side, carries out lavage and drainage simultaneously promptly, improves treatment effeciency, guarantees that the articular intracavity hydrops is fully washed totally.
