Abstract

The invention discloses a multifunctional puncture instrument, which includes a bracket and a positioning device. The positioning device includes: two arc-shaped rails, a positioning rod and a puncture needle frame, wherein the two ends of the positioning rod are respectively movably connected to the The two arc-shaped rails are connected, the puncture needle holder is connected with a puncture needle holder installation seat, and the puncture needle holder installation seat is connected with the positioning rod through a connecting arm. The present invention realizes arbitrary directional adjustment of the puncture needle through the connection mode between the connecting arm, the spherical joint and the puncture needle holder mounting seat, so that the optimal path from the puncture point to the lesion target can be determined through simple operations. And accurately cut the puncture needle into the target point.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a multifunctional puncture instrument. Background technique [0002] At present, when performing positioning puncture operations, medical personnel need to rely on the experience and technical level of the operator to puncture the target according to the relationship between the scale points on the scan chart and the puncture points. This operation requires repeated scanning to determine the position of the puncture needle, which is cumbersome and requires a large radiation dose for the patient. [0003] At present, conventional puncture instruments in this field have a simple structure, limited adjustment range, unstable fixation, and cannot simply and effectively locate the puncture point. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a multifunctional puncture instrument that can determine the optimal path fro...
