Head supporting device for neurologic cerebral angiography

Abstract

The invention provides a head supporting device for neurologic cerebral angiography. The head supporting device comprises a bottom box, wherein a traction motor is fixedly mounted in the bottom box; two movable plates are mounted in the bottom box through two sliding mechanisms; a winding roller is fixedly mounted at a driving end of the traction motor; traction ropes are fixedly connected between the two movable plates and the winding roller; two compression springs are fixedly mounted between the two movable plates and the bottom box; vertical rods are fixedly mounted on the two movable plates; thread rods I are mounted on the two vertical rods through threads; and clamping plates are mounted between the two thread rods I and the corresponding vertical rods through limiting mechanisms. The head supporting device provided by the invention has the advantages that the head of a patient can be supported and the supporting height and the supporting angle can also be flexibly adjusted; and the head of the patient can be clamped and fixed, so that the patient does not shake in an angiography process and an angiography result is not influenced.

Description

technical field [0001] The invention relates to the technical field of neurology, in particular to a head support device used in neurology for cerebral angiography. Background technique [0002] Contrast radiography refers to taking radiographs of the parts of the body of the pre-diagnosed patient with substances containing elements with high atomic numbers for medical diagnosis. It is widely used in the observation of cerebral blood vessels in neurology. During the process of radiography observation , it is usually necessary to set up a supporting device to support the patient's head, so as to facilitate the imaging work; [0003] The existing supporting device still has the following deficiencies in use: [0004] 1. The existing support devices usually only have the function of support, but the height of the support cannot be adjusted, making it impossible to support according to the needs of different patients; [0005] 2. The existing support device cannot deflect the ...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing support devices usually only have the function of support, but the height of the support cannot be adjusted, making it impossible to support according to the needs of different patients;

[0005] 2. The existing support device cannot deflect the angle, so that the patient needs to deflect the direction of the head during the imaging process, which is troublesome;

[0006] 3. At present, there is no positioning device in the device, which cannot support the patient's head, which makes the patient easy to shake during the imaging process, which affects the accuracy of imaging and has certain limitations.
