Abstract
The utility model discloses a CT lumbar intervertebral disc minimally invasive puncture positioning device, and relates to the technical field of CT lumbar intervertebral disc puncture. Comprising an arc-shaped mounting frame, and rollers are arranged on the two sides of the bottom of the mounting frame; and the positioning mechanism is arranged on one side of the mounting frame. The arc-shaped mounting frame is arranged and can be matched with the waist shape of a human body during use, so that the needle moving shaft distance of a puncture needle is reduced, and the puncture precision can be effectively guaranteed; by arranging the positioning mechanism, a CT lumbar intervertebral disc minimally invasive puncture needle and a catheter can be quickly adjusted and positioned during CT lumbar intervertebral disc minimally invasive puncture, and the positioning effect of the device is improved; by arranging the limiting assembly, the position of the positioning device can be rapidly adjusted; by arranging the limiting disc and the spring, the direction of the supporting frame on the mounting block can be adjusted according to the puncture requirement, so that the puncture requirements of different angles are met; the problems that in the prior art, the puncture shaft distance is long, precision is low, and the puncture angle is inconvenient to adjust are solved.
