Description

Technical Field

[0001] The invention relates to the field of head treatment, in particular to a head fixator used for neurointerventional treatment. Background Art

[0002] Among the interventional diagnosis and treatment surgeries in major hospitals, neurointerventional diagnosis and treatment surgeries account for a very large proportion. Neurointervention, with its advantages of less trauma and faster recovery, has become a technology vigorously developed by the neurology, neurosurgery, and radiology departments of major hospitals. During neurointerventional treatment of the head, the head needs to be fixed and supported. Although in actual operations most neurointerventional surgeries use local anesthesia or intravenous anesthesia, the head still needs to be firmly fixed and supported to avoid awakening or subconscious movement during the operation due to different tolerance levels of patients to anesthetics. The existing head fixation device is inconvenient to quickly clamp and stabilize the head according to the actual situation of the patient during neurointerventional treatment, affecting the efficiency of use. At the same time, it is inconvenient to perform auxiliary adjustment during use, which can easily cause discomfort to the patient and affect the effect of use.

[0003] In contrast, the Chinese invention patent with publication number CN116172826A discloses a head fixator for neurointerventional treatment, which supports the head by supporting the head at multiple points and uses the offset of the head for coordination adjustment; However, through understanding the existing technologies in related fields, it is known that before and during the operation, because the patient will swing his head consciously and unconsciously, and the doctor also needs to make timely adjustments according to the patient's nerve feedback, in the current fixation field, most of them use a rigid support with a gasket fixation method. Although it can have a certain fixation effect on the head, the fixation method is too rigid, and during the swinging of the head, the pressure at each point will change, causing nerve compression or discomfort to the patient, and it is also impossible to provide effective data feedback to the doctor.

By applying a fixing effect to the neck and a tightening force to the shoulder, the head, neck and shoulders are restricted under multi-directional forces, and at the same time, the gas pressure of the cylinder is used for restriction to avoid inappropriate damage caused by rigid restriction, and to ensure the restriction effect when the pressure is sufficient.

[0025] In this embodiment, the force-applying mechanism 4 includes a pressurized cylinder 42 and a parallel cylinder 43. The pressurized cylinder 42 is arranged inside the supporting mechanism 1 and is located at the lower side of the trachea 26. The parallel cylinder 43 is arranged at the lower side of the supporting airbag 35, and the parallel cylinder 43 is connected to the supporting airbag 35 through a pipeline.

After the external display connected to the pressure sensor 23 displays the pressure data, the air pump is stopped, and the adjustment knob 41 is rotated at this time to make the telescopic component 44 drive the piston 45 to The pressurized air cylinder 42 is internally compressed, and since all the clamping airbags 25 and the supporting airbags 35 are connected to the same air pressure channel, the pressure on the head, neck, and shoulders relative to the flip fixing block 21, the center fixing block 22, the neck limit block 31, and the shoulder limit block 32 is balanced and uniform, thereby ensuring the clamping effect. Moreover, because the air is compressible, the patient will not feel that the clamping force is too tight, and the surgery is performed after fixation. During the operation, when the patient's head tends to shift, the pressure sensor 23 can also provide timely feedback, thereby providing the doctor with multiple data references.
