Thoracic lumbar puncture positioning device

Abstract

The invention discloses a thoracic lumbar puncture positioning device, and relates to the field of medical instruments. The device comprises a circular truncated cone body with the bottom face being a plane and the front face being an arc face. The edge of the circular truncated cone body is provided with a groove. Eight positioning holes are formed in the circular truncated cone body. The opening walls, at one end of the arc face, of the positioning holes are ramps with wide front portions and narrow rear portions. The problems that thoracic lumbar positioning puncture difficulty is large, doctors cannot easily master the operation, the probability that complications are caused to a patient is large due to the fact that the puncture operation time is long, the patient and the doctors in the operation suffer the large amount of iatrogenic X ray radiation, and the potential or accumulated radiation injury possibility is large are solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a positioning device used before thoracolumbar puncture. Background technique [0002] In the traditional vertebroplasty positioning puncture, the doctor needs to hold the puncture needle with bare hands, and repeatedly locate, puncture, and insert the needle under the fluoroscopy monitoring of the C-arm X-ray machine. Because of the lack of spinal bony landmarks exposed under open surgery, doctors need to go through dozens or even dozens of X-ray fluoroscopy to adjust the position and direction of the puncture needle before accurately inserting the needle through the pedicle. Therefore, the traditional vertebroplasty positioning puncture through the pedicle approach has the following problems: the puncture is difficult, and it is difficult for the surgeon to master; the long puncture operation time leads to a high probability and high risk of complications for patien...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a thoracolumbar puncture positioning device, which can solve the difficulty of thoracolumbar puncture positioning and difficulty for surgeons; the long puncture operation time will lead to a high probability of complications for patients and the problems caused by patients and doctors during the operation. Exposure to large doses of iatrogenic X-ray radiation, potential or cumulative radiation damage, etc.
