Head air bag fixing device capable of being adjusted in multiple directions

Abstract

The head air bag fixing device comprises a head support and a linkage assembly capable of being adjusted in multiple directions, the head support is arranged at the end of an operating bed through the linkage assembly, a clamping and fixing assembly is arranged on the head support; the clamping and fixing assembly comprises a plurality of air cushions, each of the air cushion comprises a base and an air bag capable of deforming according to air pressure; the head support is provided with a plurality of open grooves, the base is located in the head support, the air bag is exposed out of the inner side face of the head support through the open grooves, the clamping and fixing assembly further comprises a breather pipe and an air pump used for inflating and deflating the air bag, and the air bags in the air cushion are communicated through the breather pipe. When the head support is matched with a medical worker for an operation, the head is stably placed in the head support through the air cushions in the head support, and the head of a patient is prevented from shaking in the operation treatment process; moreover, the angle of the head in the head support can be finely adjusted by controlling different inflation degrees of the air cushion, so that the requirement for fine adjustment of the head in the operation process is met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-directional adjustable head airbag fixing device. Background technique [0002] Arterial thrombectomy is an effective method for the treatment of acute large vessel occlusion stroke, and it is also a delicate and minimally invasive surgery. The diameter of the main trunk and branches of the middle cerebral artery is about 1-2mm. The twisting of the patient's head during the operation will seriously affect the display of the cerebral blood vessels, increase the risk of the operation, and prolong the operation time. Therefore, the fixation of the head is particularly important. [0003] In current technology, when performing arterial thrombectomy, the patient lies on the operating table, and the medical staff fixes the patient's head with a strap, and spreads an air bag or a sponge pillow on the back of the patient's neck to support the patient's head.

AI Technical Summary

Problems solved by technology

[0005] 1. The medical staff fix the patient's head with the hospital bed with straps. The straps are easy to fall off and are not very stable. The patient's head is easy to move during the operation, causing medical accidents, and the medical staff need to pay more attention to the patient's head at any time. , increasing the workload of medical staff

[0006] 2. During arterial thrombectomy, it is necessary to adjust the patient's head according to the patient's specific operating position. If the airbag is simply placed on the back of the patient's neck, its height is difficult to fine-tune, and because the airbag gas is easy to move, If the patient is unconscious or manic, the operation is more difficult and risky

[0007] 3. At the same time, since the two sides of the patient's head are not restricted, if the patient's head swings during DSA angiography, it will easily affect the operation and increase the difficulty and risk of the operation
