Abstract

The invention relates to the technical field of medical instruments, in particular to a positioning device for puncture and a use method thereof. The positioning device for the puncture comprises a positioning piece, a positioning ball and a fixing buckle, and is characterized in that the positioning piece is movably connected with the positioning ball, the positioning ball has elasticity, a needle inlet hole runs through the positioning ball, and the positioning piece is provided with a through hole corresponding to the needle inlet hole; the positioning ball is internally provided with a wire ring, and the plane where the wire ring is located is perpendicular to the axis of the needle inlet hole; the fixing buckle is in clamped connection on the positioning ball; the bottom of the positioning piece is provided with adhesive glue. The positioning device for puncture and the use method thereof have the advantages that the problems of outer sleeve needle puncture angle accuracy and fixation after puncture in the prior art are solved, so that the purpose of successfully reaching a target lesion through puncture operation of an outer sleeve needle at a time is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a positioning device for puncture and a use method thereof. Background technique [0002] CT-guided percutaneous lung biopsy (CT-GPLB) is one of the important contents of non-vascular interventional technology in the lung, and it is a kind of imaging technique (CT) scanning positioning, guidance, puncture A technique in which the needle reaches the lesion and performs a biopsy to obtain tissue for pathological diagnosis. Since Haga first used CT-GPLB in 1976, after decades of development and improvement, it has become a clinically mature percutaneous minimally invasive diagnostic technique. However, the accuracy of CT-GPLB puncture diagnosis is closely related to the operating experience of the puncture doctor, the accuracy of imaging positioning, the location of the lesion, the size of the tumor, the choice of puncture needle, and whether the patient cooperates. ...
