Multidirectionally-adjustable head fixing device

Abstract

The invention discloses a multidirectionally-adjustable head fixing device. The device comprises a head support and a linkage assembly capable of being adjusted in multiple directions, wherein the head support is arranged at the end of an operating bed through the linkage assembly; and the linkage assembly comprises a second fixing end, a first fixing end, a telescopic rod and a connecting plate which are sequentially connected with each other, the connecting plate is arranged to be arc-shaped, a sliding block is arranged on the inner arc face of the connecting plate, a sliding groove is formed in the bottom of the outer side of the head support, the length direction of the sliding groove is perpendicular to the length direction of the telescopic rod, the connecting plate is arranged at the bottom of the head support through the sliding block and the sliding groove, the sliding block slides in the sliding groove, an anti-disengaging block used for preventing the sliding block from disengaging from the sliding groove is arranged at the top of the sliding block, and the thickness of the anti-disengaging block is larger than the thickness of the sliding block. The multidirectionally-adjustable head fixing device can effectively control the head of a patient on the operating bed to be fixed at multiple angles when matched with medical staff in an operation, the neck of the patient can be better exposed conveniently, operation is facilitated, and operation time is saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-directional adjustable head fixation 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. [0004] The abo...

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
