Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a head fixing device for neurosurgical nursing. Background Technique

[0002] Neurosurgery is a branch of surgery. Based on surgery as the main treatment method, it applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related affiliated organs, such as the skull, scalp, cerebrovascular meninges, etc. for injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or functional disorders. After the relevant surgery on the patient's head, it is necessary to cooperate with nursing equipment to fix the patient's head.

[0003] During the use of existing head fixing devices for neurosurgical nursing, there are still some problems. The current fixing devices use bandages to fit on the forehead and are fixed at both ends on the brackets to fix the head. During the fixing process, being too tight will cause continuous pressure on the forehead and scalp, resulting in local tissue ischemia and hypoxia, and ultimately forming pressure sores. A too loose bandage may cause the fixing device or surgical instruments to slip off, accidentally injuring the patient. Moreover, the straps of traditional head fixing devices are easily contaminated by microorganisms such as bacteria and fungi during use, increasing the risk of postoperative infection. Therefore, those skilled in the art have provided a head fixing device for neurosurgical nursing to solve the problems raised in the above background technique. Summary of the Invention

[0049] The sterilization belt body 4031 is a bandage coated with sterilization material on the surface. The material of the sterilization material is one or more of silver-based materials, copper-based materials, zinc-based materials and antibacterial peptides. When sweat stains appear on the restraint belt 403 and the forehead part, the sterilization material coated on the surface of the sterilization belt body 4031 sterilizes the patient's sweat, and sterilizes through one of silver-based materials, copper-based materials, zinc-based materials and antibacterial peptides, inhibits the growth of microorganisms, and reduces the risk of infection. If the patient has an allergic reaction, or it is known that there is an allergic reaction to the patient's skin, then it is removed through the two male buckle fasteners 401 and the two female buckle fasteners 402, and the sterilization belt body 4031 with different materials of sterilization materials is replaced for use, providing safety and flexibility.

[0050] Rotate the two turntables 11 forward. The two turntables 11 drive the two threaded rods 10 to rotate, so that the two clamping plates 15 are clamped on both sides of the patient's head, which is convenient for providing more stable fixation and can be adjusted according to the patient's head. The two first electric telescopic rods 13 can also be adjusted according to the head circumference. When the driving structure 9 drives the two support frames 2 to move, the position can also be adjusted according to the position of the patient's forehead, greatly increasing the flexibility of the equipment use.

[0051] Working principle: When in use, the patient's head is placed on the flexible pad 303. By controlling the extension and contraction of the second electric telescopic rod 301, the substrate 302 is pushed up and down, which is convenient for adjusting the height of the flexible pad 303 according to the patient's own habit, and improving the comfort of the patient after fixation.

[0052] According to the position of the patient's forehead, the servo motor 904 is controlled to start. The servo motor 904 drives the transmission worm 905 to rotate. The transmission worm 905 drives the transmission worm wheel 906 to rotate. The transmission worm wheel 906 drives one of the synchronous wheels 902 to rotate. Through the synchronous belt 903, the other synchronous wheel 902 rotates synchronously, thereby driving the two lead screws 901 to rotate synchronously, so that the two support frames 2 move back and forth along the two chutes 5 synchronously, facilitating the movement of the fixing structure 4 to the forehead part of the patient.

[0053] Then, the two buckle female buttons 402 are connected to the two buckle male buttons 401. The sponge belt 4032 is attached to the forehead position of the patient. The pressure between the sterilization belt body 4031 and the patient's forehead is monitored by a plurality of pressure sensors 4033. When the pressure is too high, the two first electric telescopic rods 13 are controlled to extend, so that both ends of the sterilization belt body 4031 rise to relieve the pressure. When the pressure is too low, the two first electric telescopic rods 13 are controlled to contract, thereby driving the sterilization belt body 4031 to descend to increase the pressure, facilitating the adjustment of the pressure and preventing the influence caused by too high or too low pressure.

[0054] During the use process, when sweat stains appear on the restraint belt 403 and the forehead part, the sweat of the patient is sterilized by coating the surface of the sterilization belt body 4031 with a sterilization material. Sterilization is carried out by one of silver-based materials, copper-based materials, zinc-based materials and antibacterial peptides to inhibit the growth of microorganisms and reduce the risk of infection. If the patient has an allergic reaction, or it is known that the patient has an allergic reaction to the skin, then the two buckle male buttons 401 and the two buckle female buttons 402 are used to remove them, and the sterilization belt body 4031 with different material sterilization materials is replaced for use, providing safety and flexibility.

[0055] Then, the two turntables 11 are rotated forward. The two turntables 11 drive the two threaded rods 10 to rotate, so that the two clamping plates 15 are clamped on both sides of the patient's head, facilitating more stable fixation and being adjustable according to the patient's head. The two first electric telescopic rods 13 can also be adjusted according to the head circumference. When the driving structure 9 drives the two support frames 2 to move, the position can also be adjusted according to the position of the patient's forehead, greatly increasing the flexibility of the equipment use.
