Description

TECHNICAL FIELD

[0002] In the field of clinical diagnosis and treatment and medical image examination in neurosurgery, the head positioning device is an indispensable key equipment. During the detection process, the patient needs to lie or sit on the examination bed and keep relaxed. A quiet detection environment needs to be ensured during the detection process, and the patient needs to keep the body still to avoid speaking, swallowing, coughing and other actions to reduce interference. At this time, the electroencephalogram instrument starts to record the basic electrical activity of the brain. This process usually lasts for 5-10 minutes, and the patient should try to relax and not be nervous. This kind of device is mainly used to keep the patient's head stable during various detection and treatment processes to ensure the accuracy and safety of medical operations. The head positioning device, as an important auxiliary tool, provides reliable technical support for the accurate implementation of neurosurgery diagnosis. Various types of head positioning devices have been widely used in the field of neurosurgery.

[0003] In the existing head positioning device, since the device is designed based on a standard head model, it is difficult to adapt to the special physiological structure of patients with skull deformity and deep complex jaw. If only the forehead is fixed to achieve positioning, the patient may still have upper and lower jaw displacement or slight oral movement during the detection process. Slight movement leads to detection data deviation, and the patient's nervousness and comfort level are dynamically changing during the entire detection process. Noise fluctuation causes abnormal basic electrical activity of the brain during detection, so long-term detection is difficult to continue, which reduces the accuracy of detection data. Therefore, the present application provides a head positioning device for neurosurgery detection to meet the needs. SUMMARY

[0045] The working principle of the technical solution provided by the present application is as follows:

[0046] First of all, the medical staff need to inform the patient in advance that the patient needs to wash the hair the day before the examination, and the patient needs to avoid taking drugs that affect the nervous system such as sleeping pills and antiepileptic drugs within 24 hours. Special cases need to inform the medical staff in advance, and the patient needs to ensure adequate sleep before the test to avoid fatigue and hunger to avoid affecting the test results.

[0047] When the patient's head needs to be detected, the medical staff guide the patient into the head positioning device. The shell 1 can be adjusted to a sitting or lying position for detection according to the detection requirements. Through the operation of the touch display screen 12, the control center (not marked in the figure) is started. When the patient sits or lies and places his head in the corresponding position, the head fixing mechanism 2 is adjusted up and down from above through the first electric sliding rail 10, and automatically fits the patient's head. At the same time, the air bag 22 is driven by the inflation pump 23, the air bag 22 slowly expands, and the adjustment ring 20 on both sides is turned inward through the electric rotating seat 200, and when it is turned to a certain degree, the air bag 22 is inflated inward at the same time, and the adjustment ring 20 stops automatically after turning to a certain degree, so that both sides can fit the patient's skull. At this time, the electric adjusting seat 242 fixed on one side of the outer wall of the adjustment ring 20 drives the adjusting plate 244 to rotate unilaterally, so that the forehead fixing assembly 24 rotates to the patient's forehead position, and the forehead pad 240 rotates slightly to make the sponge 241 on the inside evenly press on the patient's forehead.

[0048] At the same time, the noise reduction mechanism 3 is slid up and down to the patient's ear position through the third electric sliding rail 30, so that the pillow 34 supports the back of the patient's head. At this time, the ear frame 31 is turned inward through the rotating motor 32 at one end, and when the ear cover 33 fits the patient's ear, the ear frame 31 stops rotating, and the sponge on the surface of the ear cover 33 achieves the effect of noise reduction. Physical sound insulation can reduce the patient's nervousness during the detection process. The sponge material effectively reduces environmental noise through the principle of physical sound insulation, creating a quiet and comfortable detection environment for the patient, and relieving the patient's anxiety during the examination.

[0049] The occlusion fixing mechanism 4 is driven by the second electric sliding rail 11, and moves horizontally to one side of the patient. The fourth electric sliding rail 41 drives the fixing seat 44 to move through the support rod 43, and the fixing seat 44 drives the buckle block 46 to move through the support column 45. The lug plate 460 on the buckle block 46 is inserted into the groove of the occlusion module 47, the fixed strip 461 increases the friction, and the patient can adjust the fixed strip 461 with different limiting to make the opening and closing angle of the occlusion module 47 smaller, and the range of motion of the patient's temporomandibular joint is smaller. The size of the occlusion module 47 can be replaced according to the size of the patient's mouth. At this time, the buckle block 46 drives the occlusion module 47 to move to the patient's mouth. (such as Figure 7The outer layer of the occlusion module 47 is provided with a disposable isolation film, which is fixed by hooks 471, and provides a barrier protection. The edges of the film are surrounded by a ring of sponge, which is used to absorb saliva and secretions in the patient's mouth. The silicone tray 470 is perfectly matched with the patient's tooth structure. The occlusion module 47 is made of silicone material, and has multiple groups of through holes inside to promote the flow of gas inside the patient's mouth. Through the fixation of the occlusion module 47 to the patient's mouth, the restraint force fixes the patient's head as a whole. When the patient bites the silicone tray 470, the position between the upper and lower teeth does not change, avoiding slight shifts in the head caused by tooth movement, and avoiding speaking, swallowing, coughing and other actions, reducing interference.

[0050] Finally, the chin fixation module 48 is driven to move vertically by the fifth electric sliding rail 42 on the sliding seat 40, so that the chin fixation module 48 is attached to the patient's chin, and the electric lead screw 482 on the base 480 can move horizontally. At this time, by adjusting the steering and extension of the adjusting rod 484, the chin support 483 is attached to the chin area of the patient. The medical staff adjusts the flexible arm 485 (not marked in the figure) between the two chin supports 483 to form an arch-shaped connection structure according to the patient's chin, and the middle support space is adapted to the contour of the patient's chin to complete the effective support of the chin.

[0051] After the head positioning device fixes the patient's head, the patient's head is detected. The medical staff will paste electrodes on the patient's scalp at specific positions using special conductive paste. These positions cover different areas of the brain and are used to collect electroencephalogram signals. After the electrodes are installed, the patient needs to keep his body still. At this time, the electroencephalograph starts to record the basic electrical activity of the brain. This process usually lasts 5-10 minutes. In order to more accurately find abnormal brain electrical activity, sometimes evoked tests are needed. The medical staff can use the microphone 13 on the side of the shell 1 to transmit voice and let the patient perform the open and close eye test. The patient opens and closes his eyes according to the instructions during the voice transmission process. At this time, the medical staff observes the changes in brain waves and makes detection records. The medical staff does not need to speak loudly to patients with hearing difficulties, reducing the physical burden of medical staff.

[0052] In order to more accurately find abnormal brain electrical activity, evoked tests are often needed. Common ones include the open and close eye test, which makes the patient open and close his eyes according to instructions during the recording process to observe changes in brain waves. There is also a flash stimulation test that uses different frequencies of strong light to stimulate the eyes to see the brain's electrical activity response. For patients suspected of having epilepsy, an overbreathing test may also be performed, which makes the patient take rapid deep breaths for about 3 minutes to induce potential epileptiform discharges.

[0053] After the above steps are completed, the medical staff will remove the electrodes, wipe the conductive paste on the scalp, and as the medical staff lightly touches the display screen 12 to unlock the device, the head fixation mechanism 2, the noise reduction mechanism 3 and the bite fixation mechanism 4 automatically return to the initial state, and the patient can leave, the medical staff wipes the device and installs a new disposable film on the bite module 47, arranges the next patient to continue detection, and improves the detection efficiency.

[0054] If an emergency or emergency occurs, the patient can immediately press the electric switch 400 located on the side of the sliding seat 40, and the electric switch 400 can quickly loosen the head fixation mechanism 2, the noise reduction mechanism 3 and the bite fixation mechanism 4 through the setting of the control center (not marked in the figure) program, so that the patient can quickly get rid of the device.

In order to make the public have a thorough understanding of the present application, specific details are described in the following preferred embodiments of the present application, and the present application can also be completely understood without the description of these details for those skilled in the art. In addition, in order to avoid unnecessary confusion to the essence of the present application, well-known methods, processes, procedures, elements and circuits are not described in detail.

[0056] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principle of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be regarded as the protection scope of the present application.
