Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pressurized headgear for skull shaping. Background Art

[0002] Skull injury refers to a fracture of the skull or a skull defect caused by surgery due to external force on the head. The main causes of skull defect fenestration can be various accidents, such as car accidents, construction site accidents, falls or the need for surgery.

[0003] As the incidence of severe craniocerebral injuries increases, a small number of patients develop subdural effusion, which causes brain tissue to shift and bulge, and this situation often occurs on the left and right sides of the brain.

[0004] At present, doctors in clinical practice mainly reshape the skull and brain tissue by manual resetting to reduce the occurrence of subdural effusion, that is, fix the skull and brain with a bandage, and manually apply appropriate force to judge the size of the intracranial pressure to reset it. This method is relatively subjective. If the bandage is not properly wrapped and fixed, it is easy to shift. It depends on the operator's independent judgment of the size of the intracranial pressure and whether pressure needs to be applied to the corresponding part. The amount of pressure applied is difficult to control, and there are also requirements for the body position of some patients. The winding is complicated, which adds certain troubles to clinical medical staff. At the same time, it also has a certain impact on the patient's skull repair and postoperative recovery.

[0005] Therefore, this patent aims to solve the shortcomings of the existing technology and proposes a device for shaping the skull and brain tissue while reducing the occurrence of subdural effusion. It is convenient for medical staff to operate, the pressure can be controlled, and it is beneficial to restore the integrity of the skull and continue the next step of craniocerebral repair surgery.

[0009] In a possible design, the fixed adjustment assembly includes a fixing bolt, a butterfly nut and two fixing plates, the two fixing plates are respectively fixedly connected to the side of the two fixing belts away from the hinge, the fixing bolt and the butterfly nut are respectively arranged on the side of the two fixing plates away from each other, and the fixing bolt passes through the two fixing plates and is threadedly connected in the butterfly nut.

[0010] In a possible design, the pressure regulating assembly includes two adjusting nuts, which are threadedly connected to both sides of the outer layer of the head cover, and both sides of the inner layer of the head cover are fixedly connected with adjusting screws, and the adjusting screws and adjusting nuts are used in combination.

[0011] In a possible design, the outer layer of the headgear is made of an inelastic hard material, the inner layer of the headgear and the fixing belt are made of an elastic hard material, and the outer layer of the headgear is harder than the inner layer of the headgear.

[0012] In a possible design, the buffer layer is made of medical silicone and the sealing layer is made of EVA.

[0013] In the present application, when used clinically, first open the butterfly nut of the fixing belt and adjust the pressure adjustment knob to make it roughly suitable for the patient to wear. If there is a protruding skull, first deal with the protruding skull, then place a layer of medical gauze to cover the wound, put on the headgear, adjust the position of the fixing belt, and adjust the butterfly nut and fixing bolt of the fixing belt to a suitable degree. Rotate the pressure adjustment knob to increase the space distance between the outer layer of the headgear and the inner layer of the headgear. When the outer layer of the headgear does not move, the inner layer of the headgear moves toward the side close to the skull to give a certain degree of pressure, so that the displaced or bulging brain tissue can be reset and reshaped. Take off the headgear after use.

[0014] According to the level of intracranial pressure, the pressure adjustment knob is tightened slowly and regularly to gradually shape the skull and brain tissue to a good degree, while reducing subdural effusion and various related symptoms caused by excessive intracranial pressure. The operation is simple and time-saving, and the clinical practicality is strong.

The buffer layer attached to the inner layer of the headgear plays a buffering and shock-proof role, reducing various discomfort reactions caused by excessive subdural effusion leading to high intracranial pressure in patients.
