Description

Head fixing device for child bronchoscopy alveolar lavage Technical Field The invention relates to the technical field of medical equipment, in particular to a head fixing device for child bronchoscopy alveolar lavage. Background Child bronchoscopic alveolar lavage is an important clinical diagnosis and treatment technology in the pediatric respiratory field, and physiological saline is injected into bronchoalveoli through a bronchoscope and sucked, so that alveolar lavage fluid is obtained for etiology, cytology and other examinations, or for treating lung diseases (such as lung infection, atelectasis and the like). In this operation, the patient is usually required to take a supine position, and in order to facilitate the smooth passage of the bronchoscope through the glottis and into the bronchi at all levels, the patient's head is often required to be kept in a reclined position to fully expose the airway and maintain a clear view of the operation. The existing operation modes and the existing problems mainly comprise: 1. Because the children are older and have weaker self-control capability, the children often generate involuntary head shaking due to fear, foreign body sensation or cough reflection in the operation process; At present, the medical staff is mostly relied on to manually assist in fixing the head of the infant clinically, or the manual fixing is restrained by using a simple binding belt, so that the manual fixing not only consumes manpower, but also is difficult to keep absolute stability for a long time, the simple binding belt is easy to loose, once the head moves in a mess, the bronchoscope is extremely easy to damage airway mucosa, and the risk and difficulty of operation are increased. 2. The sizes and the head circumferences of children at different ages are greatly different, and most of the existing fixing devices are of fixed size structures, so that the head sizes of different children are difficult to adapt quickly; in addition, the hard fixing material is directly contacted with the skin of the infant, which is easy to cause the impression and even damage of the ear and the forehead, and increases the uncomfortable feeling and crying of the infant, thereby affecting the operation coordination degree. 3. The reclining angle of the head is often required to be adjusted according to operation needs in operation, the existing adjusting device often lacks consideration to the physiological characteristics of the neck, and when the angle is adjusted, if the supporting device lacks the degree of freedom of relative displacement with the fixing point of the head, excessive traction is easily caused on fragile neck muscles of children patients, even cervical vertebra injury is caused, so that the head fixing device for child bronchoscopy alveolar lavage is provided. Disclosure of Invention Accordingly, embodiments of the present invention provide a head fixation device for bronchoscopy alveolar lavage of children, which solves or alleviates the technical problems of the prior art, and provides at least one advantageous option. The technical scheme of the embodiment of the invention is that the head fixing device for the child bronchoscope alveolar lavage operation comprises a backrest base, wherein a neck pillow block is integrally formed on the upper surface of the backrest base, a rotating groove is formed in one side of the backrest base, a fixing rod is arranged on the inner wall of the rotating groove, one end of the fixing rod penetrates through a head rotating plate and is rotationally connected through a bearing, an electric push rod is hinged to the upper surface of the backrest base through a pin shaft, a piston rod of the electric push rod is hinged to the lower surface of the head rotating plate through a pin shaft, and a head fixing assembly is slidingly connected to the upper surface of the head rotating plate. In some embodiments, the head fixing assembly comprises a head rest movable block, two fixing plates, two springs, two head clamping plates, a fixing belt and a winding mechanism, wherein the lower surface of the head rest movable block is connected to the upper surface of the head rest movable block in a sliding mode, a groove is formed in the upper surface of the head rest movable block, the groove is formed in the upper surface of the head rest movable block, a fourth silica gel pad is arranged on the inner wall of the groove, a mounting groove and an operation through hole are formed in the upper surface of the head rest movable block respectively, one side of the fixing belt is arranged on the inner wall of the mounting groove, the two head clamping plates are connected to the upper surface of the head rest movable block in a sliding mode, two fixing plates are symmetrically arranged on the upper surface of the head rest movable block, one ends of the two springs, which are repulsive, are arranged on one sides of the two head clamping plates, which are repulsi
