Technical Field
[0001] This utility model relates to the field of medical and nursing equipment technology, and in particular to a head fixation device after craniocerebral trauma surgery. Background Technology
[0002] Traumatic brain injury (TBI) is a common type of traumatic injury that can occur alone or in combination with other injuries. Based on the anatomical location of the brain, it is classified into scalp injuries, skull injuries, and brain injuries. These three types can coexist. Common causes include traffic accidents, falls from heights, accidental falls, workplace accidents, and firearm injuries. TBI in infants is occasionally caused by dystocia or forceps delivery. Surgical treatment is generally employed to treat TBI. The principles of surgical treatment for TBI are to save the patient's life, restore vital neurological functions, and reduce mortality and disability rates. Surgical treatment is mainly for open craniocerebral injury, closed craniocerebral injury with intracranial hematoma, or complications or sequelae caused by craniocerebral trauma. After surgery, the patient's head should be turned to one side to prevent vomit or secretions from blocking the airway. While under general anesthesia, the patient should be kept in a supine position with the head turned to the healthy side. After awakening and with normal blood pressure, the head of the bed can be elevated to facilitate venous blood return from the head and reduce cerebral edema. However, in the current postoperative recovery process, only ordinary pillows can be used to support the patient's head. This fixation method has poor stability and cannot be adjusted according to the patient's condition. It also cannot effectively support and fix the head in a semi-recumbent position. Therefore, a head fixation device for craniocerebral trauma surgery that can support the patient's head in a semi-recumbent position is needed. Utility Model Content

[0027] The following is in conjunction with the appendix Figures 1-8 The specific embodiments of this utility model will be described in further detail.
[0028] Example 1, by Figures 1-5 The device includes a fixation plate 1, which is installed at the head of the patient's bed. To assist in tilting the patient's head to one side, a buffer plate 2 is slidably connected to the upper end of the fixation plate 1. The buffer plate 2 can slide relative to the fixation plate 1, so that the head can still be supported and fixed when the patient is adjusted to a semi-reclined position. A support plate 3 is slidably connected to the upper end of the buffer plate 2. The support plate 3 can slide up and down relative to the buffer plate 2, so as to adjust the support height for the patient's head according to the patient's postoperative needs. Two symmetrically arranged tilting airbags 4 are fixedly connected to the upper end of the support plate 3. In use, the tilting airbags 4 are placed on both sides below the patient's head. The support for the patient's head is adjusted by adjusting the expansion degree of the two tilting airbags 4. When one tilting airbag 4 expands, the other tilting airbag 4 contracts. When the patient's head is tilted towards the contracted airbag 4, the airbag flips to tilt the patient's head to one side, facilitating postoperative recovery. The lower end of the support plate 3 is fixedly connected to the inflatable airbag 5, and the other end of the inflatable airbag 5 is fixedly connected to the upper end of the buffer plate 2. The inflatable airbag 5 forms a sealed cavity between the support plate 3 and the buffer plate 2. The relative height between the support plate 3 and the buffer plate 2 is controlled by adjusting the air pressure in the cavity, so as to suit different patients. The lower end of the fixed plate 1 is rotatably connected to the limiting plate 6, and the middle part of the fixed plate 1 is provided with a limiting component 7. The limiting component 7 and the limiting plate 6 cooperate to form the limiting structure of the buffer plate 2. When the patient is adjusted to a semi-reclining position, the limiting component 7 can prevent the fixed plate 1 and the buffer plate 2 from sliding relative to each other, making it suitable for different patients.
[0029] Example 2, based on Example 1, is... Figures 1-3As shown, in order to support the patient's neck, a support airbag 8 is fixedly connected to the upper end of the support plate 3. The support airbag 8 is placed on one side of the inclined airbag 4. When in use, the support airbag 8 is placed on the patient's neck and expands to support the patient's neck and help fix the patient's head. The lower end of the support airbag 8 passes through the support plate 3 and is connected to a support trachea 9. The lower end of each inclined airbag 4 is connected to an inclined trachea 10. The support trachea 9 and the inclined trachea 10 are both placed below the support plate 3 and are fixedly connected to the support plate 3.
[0030] Example 3, based on Example 2, by Figures 1-3 To achieve better results, the upper end of the support plate 3 is fixedly connected to a first air injection port 11, each of which is connected to an inclined air tube 10. The upper end of the support plate 3 is fixedly connected to a second air injection port 12, which is connected to a support air tube 9. The upper end of the support plate 3 is fixedly connected to a third air injection port 13, which is connected to an inflatable airbag 5. The first air injection port 11, the second air injection port 12, and the third air injection port 13 are all made of rubber and have puncture holes in their middle. Air can be injected into the corresponding airbag using a basketball inflation needle and an air pump, and air can also be expelled from the corresponding airbag using a basketball inflation needle.
[0031] Example 4, based on Example 1, by Figure 1 and Figure 4 To achieve a better purpose, the upper end of the fixed plate 1 is provided with a plurality of symmetrically arranged guide grooves 14, and the lower end of the support plate 3 is fixedly connected with a plurality of extension sliders 15. Each extension slider 15 is placed in the corresponding guide groove 14 and can slide along the corresponding guide groove 14. The extension slider 15 cooperates with the guide groove 14 to restrict the sliding direction of the support plate 3.
[0032] Example 5, based on Example 4, by Figures 3-6 To improve the sealing performance of the support plate 3 during sliding, a sealing ring 16 is fitted on the outer side of each extension slider 15. Each sealing ring 16 is uniformly connected to the buffer plate 2. The sealing ring 16 can effectively prevent air leakage inside the expansion airbag 5.
[0033] Example 6, based on Example 4, by Figures 3-6To accommodate different patients, the limiting structure includes a positioning pin 71 with a rounded upper end. A positioning hole 72 is provided on the fixing plate 1 corresponding to the position of the positioning pin 71. The positioning pin 71 is placed within the positioning hole 72 and can slide up and down along it. An elastic pad 73 is provided within the positioning hole 72, with its lower end contacting the positioning pin 71. The elastic pad 73 keeps the positioning pin 71 in a lower position. A positioning notch 74 is provided on the extension slider 15 corresponding to the position of the positioning pin 71, allowing the upper end of the positioning pin 71 to be inserted... When the positioning pin 71 is inserted into the positioning notch 74, the buffer plate 2 is fixed relative to the fixed plate 1. The lower end of the positioning pin 71 corresponds to the limiting plate 6. After the limiting plate 6 is flipped into the fixed plate 1, the limiting plate 6 supports the bottom of the positioning pin, causing the positioning pin to slide upward and insert into the positioning notch 74. When the limiting plate 6 is not in the fixed plate 1, the limiting plate 6 is perpendicular to the fixed plate 1 and inserts into the gap of the bed board to fix the position of the fixed plate 1. At the same time, the elastic spring pushes the positioning pin 71 to slide downward, causing the end of the positioning pin 71 to slide out into the positioning notch 74.
[0034] Example 7, based on Example 1, by Figure 7 and Figure 8 To achieve cushioning, a buffer cavity 17 is provided within the fixed plate 1. The buffer cavity 17 is pre-filled with gas, and a buffer slider 18 is slidably connected within the buffer cavity 17. A sealing ring 19 made of rubber is fitted onto the outer side of the buffer slider 18 to improve the sliding sealing performance of the buffer slider 18. A support rod 20 is fixedly connected to the front end of the buffer slider 18, passing through the upper end of the fixed plate 1. The other end of the support rod 20 is fixedly connected to the buffer plate 2. During use, the buffer plate 2 slides relative to the fixed plate 1, and simultaneously, the buffer plate 2 pushes the buffer slider 18 to slide within the buffer cavity 17 via the support rod 20. During this process, the gas within the buffer cavity 17 is pressurized to prevent the buffer plate 2 from sliding rapidly and causing vibration, thereby preventing injury to the patient's head.
[0035] Example 8, based on Example 7, by Figure 7 and Figure 8To adjust the buffering level, an adjusting slider 21 is slidably connected within the buffer cavity 17. An adjusting screw 22 is fixedly connected to the other end of the adjusting slider 21. An adjusting screw tube 23 is threaded onto the outer side of the adjusting screw 22. The side of the buffer cavity 17 corresponding to the adjusting screw tube 23 is connected to the outside, allowing the adjusting slider 21 to slide within the buffer cavity 17. The other end of the adjusting screw tube 23 passes through the end of the fixed plate 1. An adjusting notch 24 is provided at the end of the adjusting screw tube 23. The adjusting notch 24 can be a hexagonal socket or similar structure to facilitate the rotation of the adjusting screw tube 23. During use, rotating the adjusting screw tube 23 causes the adjusting screw 22 to push the adjusting slider 21 to slide within the buffer cavity 17, thereby adjusting the air pressure within the buffer cavity 17 and changing the sliding distance of the buffer plate 2 relative to the fixed plate 1. When the adjusting slider 21 approaches the buffer slider 18, the air pressure within the buffer cavity 17 is higher, resulting in a smaller sliding distance for the buffer plate 2; conversely, when it approaches the buffer slider 18, the buffer plate 2 can slide a larger distance.
[0036] When using this invention, the fixing plate 1 is installed at the head of the patient's bed, and the patient's head is positioned above the two tilting airbags 4. When the patient needs to tilt their head to one side after surgery, air is injected into the corresponding tilting air tube 10 using a basketball inflation needle and an air pump, causing the corresponding tilting airbag 4 to expand and push the patient's head to one side to achieve the position required for postoperative recovery.
[0037] When it is necessary to support the patient's neck, gas is injected into the second air injection port 12. The gas enters the support airbag 8 through the support air tube 9 to achieve the effect of supporting the patient's neck. When it is necessary to adjust the support height, control is injected into the third air injection port 13 to adjust the degree of expansion of the inflatable airbag 5 and change the relative distance between the support plate 3 and the buffer plate 2.
[0038] When a patient needs to be adjusted to a semi-recumbent position, the bed's adjustment function allows the patient's upper body to be turned upwards. If the patient is short, the upper body will move significantly relative to the front edge of the bed during adjustment. Therefore, before adjustment, the limiting plate 6 is flipped out from the bottom of the fixing plate 1 and hooked onto the front edge of the patient's bed. At this time, the elastic spring pushes the positioning pin 71 downwards, causing the end of the positioning pin 71 to slide out into the positioning notch 74. During the patient's position change, the buffer plate 2 can slide relative to the fixing plate 1, preventing friction between the tilting airbag 4 and the patient's head, which could cause injury to the patient. When the patient is tall, the upper body will not move significantly relative to the bed parameters during adjustment, so it is not necessary to flip out the limiting plate 6.
[0039] Before the patient switches to a semi-reclining position, a structure such as an internal hexagonal screw can be used to facilitate the rotation of the adjusting screw tube 23. During use, rotating the adjusting screw tube 23 causes the adjusting screw 22 to push the adjusting slider 21 to slide within the buffer chamber 17, thereby adjusting the air pressure within the buffer chamber 17 and changing the sliding distance of the buffer plate 2 relative to the fixed plate 1. When the adjusting slider 21 approaches the buffer slider 18, the air pressure within the buffer chamber 17 is higher, and at this time, the buffer plate 2 can slide a smaller distance, avoiding the buffer plate 2 from sliding a longer distance downward due to gravity, which would reduce the fixed support effect.
[0040] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively supports the patient's head turning, increases the function of supporting the neck, solves the problem of the patient's inability to be supported in a semi-reclining position, and adds the function of adjustable support height.
[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
