Thoracolumbar puncture positioning device

Technical Field

The utility model relates to the technical field of medical equipment.

Background

When thoracolumbar puncture is performed, a patient needs to be kept in a lateral decubitus position or a sitting position, the intervertebral space of the spine is widened to facilitate needle insertion, and then positioning and puncture are performed under the perspective monitoring of an X-ray machine. In order to improve the puncturing effect, positioning devices are available, which are used for positioning the puncturing needle, the puncture needle can puncture in place by limiting the puncture angle and the puncture depth of the puncture needle, but in actual operation, in order to avoid puncture errors, the back and the back of the patient need to be positioned, and the traditional method is that after the patient is locally anesthetized, in addition to the doctor who performs the puncturing operation, another medical worker is required to pull the back of the patient, so as to avoid the movement of the back of the patient in the puncture process, which causes puncture deviation, however, the X-ray machine is needed to perform multiple times of perspective during the puncture so as to adjust the puncture direction and depth, the time required is long, causing the medical staff restraining the back of the patient to be fatigued easily, thereby affecting the restraining and positioning effect on the patient, which in turn may affect the puncture.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the technique that exists is not enough to the aforesaid, provides a chest lumbar vertebrae puncture positioner, and patient's back can be retrained to it, avoids the puncture in-process because patient's back moves the puncture deviation problem that leads to.
