The invention relates to the technical field of medical instruments, in particular to an arc puncture device. A puncture needle and a puncture needle sleeve are of arc-shaped structures which are identical in curvature radius, and the puncture needle is arranged in the puncture needle sleeve in a sliding and matched mode. A channel allowing the puncture needle to pass is formed in a fixing plate,a through groove extending in the arc length direction of the puncture needle sleeve is formed in the pipe wall of the puncture needle sleeve, a needle handle is arranged on the tail portion of the puncture needle, and the needle handle penetrates through the through groove and extends out of the puncture needle sleeve. The arc puncture device is of a separated type structure, and disinfection andassembly are facilitated. The puncture needle sleeve is of an open structure, and after puncture is successfully completed, the fixing plate and the puncture needle sleeve can be directly removed soas to facilitate the next operation. By means of the arc puncture device, the needle entry point and the needle entry angle during puncture can be accurately controlled, an operator holds the needle handle of the puncture needle by hand and propels the puncture needle along the puncture needle sleeve, and then puncture can be completed. The operation is simpler and more convenient, the precision degree is greatly improved, the operation time is shortened, misoperation is reduced, and a patient is prevented from suffering from unnecessary tissue damage and pain.
