Abstract

The invention discloses a positioning puncture guiding device, which belongs to the field of puncture biopsy. A positioning puncture guiding device, comprising: a frame, a connecting frame, a guide tube and a positioning assembly; the connecting frame is hinged on the frame, and the connecting frame includes two connecting rods, a slider and a push rod, the The connecting rod is hinged with the frame; the push rod is horizontally arranged between the connecting rods, and the two ends of the push rod are respectively slidably connected with the two connecting rods; the slider is arranged on the push rod below, and is slidably connected with the push rod; the slider is provided with a universal coupling, and the slider is connected with the guide tube through the universal coupling, and the positioning assembly includes a suction cup, Rotating tube, base, worm gear and worm screw, the middle part of the base is provided with a through hole, and the rotating tube corresponds to the guide tube; compared with the prior art, the positioning puncture guide device of the present application can provide good Support, improve the accuracy of puncture.

Description

technical field [0001] The invention relates to the field of puncture guidance, in particular to a positioning puncture guidance device. Background technique [0002] CT-guided puncture refers to the use of CT detection as a guide to determine the location of the lesion, determine the puncture point, puncture direction, and puncture force, so as to remove living tissue for pathological examination. Through puncture, accurate living samples can be obtained, and the type of lesion can be accurately determined based on this. Moreover, the wound formed by puncture is small and has little influence on the lesion, so it is widely used in medical pathological detection. [0003] At present, most of the puncture guidance is performed manually by the operator based on the CT film results and manual puncture. This method places high demands on the surgeon, who often needs years of clinical experience to make an accurate judgment. Although there are many kinds of puncture guides on ...
