Conformal puncture guiding device and preparation method thereof

Abstract

The invention discloses a conformal puncture guiding device and a preparation method thereof. The guiding device comprises a base plate and puncture processus spinosuses, wherein the base plate is a plate structure body; the puncture processus spinosuses are arranged on the base plate and are distributed and arranged on the arc-shaped base plate in inclined distribution; the included angle between the puncture processus spinosuses and the arc-shaped base plate is 20 to 160 degrees; the length of the puncture processus spinosuses is 2 to 180mm; needle feeding through holes penetrating through the base plate are formed in the puncture processus spinosuses. Through the arrangement of the base plate, the matching with the surface of the puncture position of a puncture object is convenient; through the arrangement of the puncture processus spinosuses with the included angle being 20 to 160 degrees with the base plate and the length being 2 to 180mm on the base plate, the needle feeding depth, the needle feeding angle and the needle feeding quantity of the puncture needles can be conveniently positioned, so that the accurate puncture can be realized only through using the conformal puncture guiding device without the real time observation by using large-scale medical imaging equipment such as CT (Computerized Tomography) equipment; the problems of long puncture time, radiation harm on puncture objects and doctors and the like are solved.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a conformal puncture guide for auxiliary puncture and a preparation method thereof. Background technique

[0002] At present, with the increase in the prevalence of tumors, diagnosis and treatment items such as biopsy puncture, frequent ablation, and argon-helium knife are increasingly becoming the mainstream diagnosis and treatment methods. However, these diagnosis and treatment items must be guided by large medical imaging equipment such as CT and MR. A puncture operation takes 1 to 2 hours, but a patient diagnosis only takes about 5 minutes. The existing puncture method not only wastes resources, but also causes unnecessary radiation to doctors, which is harmful to doctors. have a great impact on their health. In addition, large-scale medical imaging equipment such as CT rooms are not located in relatively sterile operating rooms, and there is no air purification equipment. Pat...
