Body position frame for lumbar vertebra functional position shooting

Abstract

The invention discloses a body position frame for lumbar vertebra functional position shooting, which comprises a base, and a left column and a right column which are installed on the base, wherein a left adjusting rod and a right adjusting rod which have the same structures and can move left and right as well as up and down are respectively arranged on the left column and the right column. Through adjusting the lateral and the horizontal positions of the left adjusting rod and the right adjusting rod, the body position frame can conveniently fix the stand over-extensive and over-flexional positions of a patient, and is easy for controlling the extensive and flexional degrees of the lumbar vertebra, accordingly, the presentation of a spondylolisthesis X-line is objectively and accurately reflected, and the accurate diagnosis of the actual spondylolisthesis degree is improved. The body position frame has a simple structure, is low in cost, facilitates the over extensive position operation, and is easy to be clinically popularized and applied.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a body position frame for taking radiographs at the functional position of the lumbar spine. Background technique [0002] At present, most X-rays of the lumbar spine are taken in the supine position. Patients will feel uncomfortable when taking the X-rays in the supine position, especially for elderly and critically ill patients. The easy movement of the body often results in poor photo quality and cannot clearly show the lesion area. In order to make the patient's lying position stable and keep a stable filming angle, a lumbar spine oblique position filming fixation device can be used, such as the Chinese patent "lumbar spine oblique filming angle frame" (publication number CN 2477141Y) discloses a kind of support plate, flat plate The filming angle frame composed of the support rod and the best filming angle can be selected and fixed, especially suitable for filmin...

AI Technical Summary

Problems solved by technology

[0004] However, there are the following problems in lumbar spine functional radiography: ①It is not easy to grasp the degree of lumbar flexion; ②The body position is not fixed and changes; ③The body may shake during the exposure; ④The X-ray centerline is routinely aligned with the third The lumbar spine, and the multiple sites of spondylolisthesis are the 4th and 5th lumbar vertebrae

The above conditions will affect the clarity of the film and the display of spondylolisthesis, which will easily lead to missed diagnosis and misdiagnosis
