Description

Technical Field

[0001] The present invention relates to the technical field related to medical auxiliary equipment, and in particular to a hand support board used in cerebral angiography. Background Art

[0002] Cerebral angiography is a minimally invasive surgery that uses brain vascular images to understand the morphology of brain blood vessels, the nature of lesions, etc., to help diagnose whether there are intracranial vascular lesions, and it also has a therapeutic effect. Before undergoing cerebral angiography, patients need to undergo head CT, electrocardiogram and other examinations, and do iodine allergy tests to avoid allergies to iodine. When it is clear that the body can undergo cerebral angiography, it is necessary to choose an anesthesia method based on the patient's physical condition, mainly including general anesthesia or local infiltration anesthesia. After the anesthesia takes effect, a catheter will be inserted into a large artery, then through the circulatory system to reach the common carotid artery, and then a catheter will be placed to inject iodine contrast agent, and the corresponding operations will be performed.

With the assistance of the pulley mechanism 6, the device can be adjusted in the front and rear positions more labor-saving, which greatly increases the practicality of the device.

[0044] Working principle:

[0045] When fixing the device, the upper splint 2 and the lower splint 3 are respectively inserted into the upper and lower positions of the outer frame of the bed, and then the first telescopic mechanism 4 is controlled by the key module 31, and the servo motor 26 drives the threaded rod 27 to rotate, and the threaded rod 27 drives the extension rod 24 to contract, so that the lower splint 3 clamps the outer frame of the bed. At this time, the auxiliary wheel 30 of the pulley mechanism 6 is close to the outer frame of the bed, and then the servo motor 26 is stopped, and the device can be pushed to move forward and backward along the outer frame of the bed. When the position is adjusted, the first telescopic mechanism 4 is controlled again, and the servo motor 26 drives the threaded rod 27 to rotate again, and controls the lower splint 3 to further contract until the pulley mechanism 6 is squeezed into the first installation groove 5, so that the upper splint 2 and the lower splint 3 tighten the bed, and then the servo motor 26 is stopped, wherein, it is also possible to clamp after the arm is fully supported;

[0046] When supporting the arm, the patient's arm is passed between the fixing belt 15 and the main supporting plate 10, and then the storage motor 17 is started, the storage motor 17 drives the winding roller 18 to rotate, the winding roller 18 wraps around the fixing belt 15, shortens the length of the fixing belt 15 outside, and the fixing belt 15 pulls the two auxiliary fixing plates 12 to move inward, thereby fitting the main supporting plate 10, the transition plate 11 and the auxiliary fixing plate 12 to the patient's arm, and then the storage motor 17 is stopped;

[0047] When adjusting the angle, first start the second telescopic mechanism 22 to drive the clamping plate 21 away from the universal gear ball 19, then rotate the hand support plate mechanism 9, and when the position is suitable, make the second telescopic mechanism 22 drive the clamping plate 21 to fit with the universal gear ball 19 for clamping to achieve a fixing effect.
