The beneficial effects of the present invention are:

(1) First, fix the TCCS probe on the TCCS probe fixing component, and then put the skull fixation component on the head, so that the first arc-shaped plate, the second arc-shaped plate and the third arc-shaped plate can be initially fixed to the skull Work, drive the first elastic arc plate and the second elastic arc plate to move relatively through the driving element, even if the first elastic arc plate and the second elastic arc plate are tightened, the patient’s head is fixed, and the tightening is controlled by the adapter element strength, the adapting element is located on the forehead of the patient, the first arc-shaped plate and the second arc-shaped plate are respectively located behind and above the patient’s two ears, and the TCCS probe is positioned at the place to be monitored by the mechanical arm, and then adjusted The assembly can adjust any angle of 180° at the monitoring point, and the adapter element can prevent the first elastic arc plate and the second elastic arc plate from being too tight, causing discomfort to the patient’s head, and at the same time can better fit The curvature of the forehead can be automatically adapted according to the size of the patient's head, and can be automatically adapted according to the size of the patient's forehead, so that it can be fixed more firmly with the patient's head without causing discomfort to the patient and avoiding TCCS The position of the probe is moved during the monitoring process. Through the monitoring of the patient by the probe of the TCCS, it is possible to know in real time which blood vessel is being monitored, the color Doppler status, and whether the monitoring position has changed, and more information can be provided to the clinic.

(2) By rotating the winding roller, the first pull rope and the second pull rope are wound on the winding roller, the first pull rope pulls one end of the fourth elastic arc plate to move into the first hollow tube, and the second pull rope pulls the second pull rope The other end of the four elastic arc plates moves into the second hollow tube to tighten the fourth elastic arc plate and fix the patient’s head. After the fourth elastic arc plate is tightened, continue to drive the winding roller to rotate to make the first The base and the second base move toward the third arc-shaped plate, so that the first elastic arc plate and the second elastic arc plate move relatively, and fix the patient's head. Make the ratchet rotate in one direction, even if the winding roller rotates in one direction, the first elastic arc plate and the second elastic arc plate can be fixed after being tightened; After pressing, the first to sixth arc-shaped rotating plates are rotated, the fifth and sixth arc-shaped rotating plates and the third and fourth springs are set, and the third elastic arcing plate can be changed The adjustment of the vertical angle is automatically adapted according to the curve of the patient's forehead, and the level of the third elastic arc plate can be changed by setting the first to fourth arc-shaped rotating plates and the first and second springs The adjustment of the direction and angle is automatically adapted according to the curve of the patient's forehead, and the first elastic arc plate to the third elastic arc plate can be fixed at the same time, and the fixing operation is simple and fast; through the above settings, the third elastic arc plate can be better deformation, and adapt to the curve of the patient's forehead, so that the third elastic arc plate can better contact the patient's skin. Through the above settings, the contact with the patient's head can be reduced, and the air permeability is good after fixation, which greatly reduces the patient's discomfort.

(3) When the head fixation assembly is taken off from the patient's skull, it is only necessary to push the push rod to move the push rod in the winding roller, so that the air in the second chamber enters the first chamber through the through hole, and the first The pressure in the chamber increases, so that the driven rod moves out of the fixed plate, and the connecting plate and the moving rod move together to completely separate the clamping plate from the ratchet, and the first elastic arc plate and the second elastic arc plate are automatically reset, so that the ratchet Reverse rotation is possible, the turntable setting can make the push rod and the bobbin rotate in reverse together, it is convenient and quick to remove, the push rod can be reset by the eighth spring, and the first chamber can be made The chamber is always in communication with the second chamber, so that the bobbin is rotatably located on the fixed disk.

(4) The screw rod cooperates with the internal thread block, thereby turning the screw rod to move the fourth hollow tube along the direction of the third hollow tube, so that the third base is away from or close to the first base, so that the TCCS probe can be close to or away from the patient The patient adjusts the distance of the TCCS probe. The ninth spring can generate a thrust on the fourth hollow tube. After the screw rotates, the fixation can be completed to avoid accidental rotation of the screw. By moving the moving frame, the TCCS probe can be moved horizontally, that is, To adjust the horizontal position of the TCCS probe, the ball on the ejector rod can be located in the arc-shaped groove through the setting of the ejector rod and the tenth spring, so as to complete the fixing of the mobile frame. When the moving force of the mobile frame is greater than the elastic force of the tenth spring , so that the mobile frame can be moved, by rotating the rotating frame, the TCCS probe can be adjusted vertically, so that the TCCS probe is at the monitoring position, through the first and second clamps and the eleventh spring and the twelfth spring The gear can be fixed. When the rotating force of the rotating frame is greater than the sum of the elastic forces of the eleventh spring and the twelfth spring, the rotating frame is rotated. When it is less than the sum of the two, the rotating frame is fixed. The angle is adjusted, and finally the TCCS probe can better complete the monitoring work of the patient. In summary, the position adjustment range of the TCCS probe is large, which can adapt to more patients and has strong versatility; through the arc surface setting, the rotation The frame is in contact with the guide plate, that is, the arc surface moves along the surface of the guide plate during the rotation of the rotating frame, so that the rotating frame is more stable during rotation.

(5) Put the TCCS probe on the fourth base, bind it through two female Velcro, and cooperate with the two sub-Velcro, the fourth base can be better adapted to the TCCS probe through the air cushion setting The surface curve is more firmly fixed to the TCCS probe; by moving the scale plate, the guide rail moves together, the slider moves, the fourth base rotates, and finally the TCCS probe rotates, and then the angle can be adjusted by turning the rotating rod The last TCCS probe is adjusted at a 360° angle, and the scale plate is fixed by screws. When the rotating force of the rotating rod is greater than the elastic force of the spring telescopic rod, the rotating rod is rotated, that is, through the spring telescopic rod and the first clamping column on it. Cooperate with the card slot on the fixing ring to fix the rotating rod. Through the setting of the arc-shaped round rod and the two second clamping posts on it, the rotating rod can be fixed more firmly. Through the above settings, the TCCS probe can be fixed The angle adjustment range is large. When the fourth base is parallel to the rotating rod, the torsion spring setting can exert a torsion force on the fourth base, which is convenient for the angle adjustment of the fourth base; It is good to determine the rotation angle of the rotating rod, and the precise angle adjustment can be performed. When the rotating rod drives the spring telescopic rod to rotate, the arc-shaped round rod can be located on the spring telescopic rod for proper movement to adapt to the rotation of the spring telescopic rod. Finally, the two The second clamping column can also be located in the clamping groove, and the rotating rod is fixed by the first clamping column and the two second clamping columns, so that the fixing is more firm.
