[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0027] One preferred embodiment of this application, such as Figures 1 to 7As shown, a head fixation device for bronchoscopy under general anesthesia includes a bed 1 and a placement part 11 mounted on the bed 1 for supporting and fixing the patient's head. A fixing post 2 is provided on the side of the bed 1 near the placement part 11. A first clamping member 21 is provided on the side of the fixing post 2, and the first clamping member 21 and the fixing post 2 are engaged by a locking structure 3. Second clamping members 22 are provided on both sides of the fixing post 2, and the two second clamping members 22 are engaged with the placement part 11. Therefore, when fixing the head of a patient under general anesthesia, the patient's head can be placed on the placement part 11, and then the locking structure 3 can be used to release the locking of the first clamping member 21. At this point, the first clamping member 21 can be moved downwards until it contacts the patient's forehead. Then, the two second clamping members 22 are pulled, and they can move closer to the sides of the patient's head. The first clamping member 21, which is in contact with the patient's forehead, can be fixed and locked to the two second clamping members 22 by the adjusting structure 4. Thus, the patient's head is fixed by the cooperation of the first clamping member 21 and the two second clamping members 22, which better keeps the patient's head fixed, making it easier for medical staff to operate, improving the practicality of the device, reducing patient discomfort, and improving the patient's treatment experience.
[0028] In this embodiment, as Figures 1 to 4 As shown, the first clamping member 21 includes a movable block 211 and an arc-shaped clamping block 212. The movable block 211 is positioned on the side of the fixed post 2, and the side of the movable block 211 and the fixed post 2 are engaged by a locking structure 3. The arc-shaped clamping block 212 is installed on the side of the movable block 211, and a locking structure 3 is provided thereto, which facilitates locking and fixing the movable block 211 after adjustment and movement, so that the arc-shaped clamping block 212 can better fit and fix the patient's head. When the patient's head is positioned, the patient can lie on the bed 1 with their head resting on the placement part 11. At this time, the locking structure 3 can be used to lock and fix the patient's head. Release the lock on the movable block 211. At this time, the movable block 211 can move along the vertical direction of the fixed column 2. When the movable block 211 moves down, it can drive the arc-shaped clamp 212 down to fit against the patient's head. Then, pull the two second clamps 22 closer to the sides of the patient's head. The sides of the arc-shaped clamp 212 that fit against the patient's forehead are fixed and locked to the two second clamps 22 through the adjustment structure 4. Thus, the arc-shaped clamp 212 and the two second clamps 22 cooperate to fix the patient's head, thereby better keeping the patient's head fixed, improving the practicality of the device, and reducing the patient's discomfort.
[0029] In this embodiment, as shown in the figure, Figure 4 , Figure 5 and Figure 6As shown, the locking structure 3 includes a locking rod 31 and a locking groove 32. The locking groove 32 is located on the side of the fixed post 2. The locking rod 31 is threaded into the locking groove 32, and the locking rod 31 extends into the side of the fixed post 2 and fits against the side of the moving block 211. When fixing, the locking rod 31 can be rotated, causing it to gradually rotate out of the locking groove 32 through the thread. At this time, the side of the locking rod 31 separates from the side of the moving block 211, thereby releasing the locking of the moving block 211. The moving block 211 can then move along the vertical direction of the fixed post 2. When the moving block 211 moves downward, it can drive the arc-shaped clamping block 212 to move downward to meet the patient's... When the patient's head is placed against the ground, the locking lever 31 can be rotated. As the locking lever 31 rotates, it gradually enters the fixing post 2, and then the side of the locking lever 31 is pressed against the side of the moving block 211 again, thereby re-locking and fixing the moving block 211. At this time, the arc-shaped clamp 212 is locked and fixed. Then, the two second clamps 22 are pulled closer to the sides of the patient's head. The sides of the arc-shaped clamp 212 that are in contact with the patient's forehead are fixed and locked with the two second clamps 22 through the adjustment structure 4. Thus, the arc-shaped clamp 212 and the two second clamps 22 work together to fix the patient's head, thereby keeping the patient's head fixed and reducing the patient's discomfort.
[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it should be understood that the second clamping member 22 includes a sliding block 221 and an inclined clamping block 222; the sliding block 221 is slidably mounted on the side of the fixed post 2, and the inclined clamping block 222 is mounted on the side of the sliding block 221, and the inclined clamping block 222 cooperates with the side of the placement part 11; then, when fixing, the locking rod 31 can be rotated so that the locking rod 31 gradually rotates out of the locking groove 32 through the thread, at which time the side of the locking rod 31 separates from the side of the moving block 211, thereby releasing the locking of the moving block 211. At this time, the moving block 211 can move along the vertical direction of the fixed post 2. When the moving block 211 moves downward, it can drive the arc-shaped clamping block 212 to move downward. When the device is positioned to fit the patient's head, the locking lever 31 can be rotated. As the locking lever 31 rotates, it gradually enters the fixing post 2, and the side of the locking lever 31 then presses against the side of the moving block 211, thereby re-locking and fixing the moving block 211. At this point, the arc-shaped clamping block 212 is locked and fixed. Then, the two sliding blocks 221 are pulled, and the movement of the two sliding blocks 221 can drive the inclined clamping block 222 connected to them to gradually approach and fit against the sides of the patient's head. At this point, the sides of the arc-shaped clamping block 212 and the two sliding blocks 221 are locked and fixed through the adjustment structure 4, which facilitates a more stable and comfortable fixation of the patient's head and reduces the patient's discomfort.
[0031] In this embodiment, as Figure 2 , Figure 6 and Figure 7 As shown, the adjusting structure 4 includes a pair of latches 41 and multiple slots 42. The pair of latches 41 are symmetrically installed on both sides of the arc-shaped clamping block 212, and the multiple slots 42 are symmetrically opened on the sides of the two sliding blocks 221. The pair of latches 41 and the corresponding slots 42 engage and cooperate. When fixing, the locking rod 31 can be rotated, causing it to gradually rotate out of the locking slot 32 through the thread. At this time, the side of the locking rod 31 separates from the side of the moving block 211, thus releasing the lock on the moving block 211. The moving block 211 can then move along the vertical direction of the fixing post 2. When the moving block 211 moves downwards, it can drive the arc-shaped clamping block 212 downwards to fit against the patient's head. At this time, the locking rod 31 can be rotated. When the locking rod 31 rotates, it gradually enters the fixed column 2, and then the side of the locking rod 31 is pressed against the side of the moving block 211 again, thereby re-locking and fixing the moving block 211. At this time, the arc-shaped clamp 212 is locked and fixed. Then, the two sliding blocks 221 are pulled. The movement of the two sliding blocks 221 can drive the inclined clamp 222 connected to them to gradually approach and fit against the sides of the patient's head. At this time, the buckles 41 on both sides of the arc-shaped clamp 212 can fit into the slots 42 on the two sliding blocks 221 according to the different heads of different patients. This makes the arc-shaped clamp 212 and the two inclined clamps 222 better fit the heads of different patients, thereby improving the practicality and convenience of the device, better locking and fixing the patient's head, and reducing the discomfort of operation for medical staff.
[0032] It should be known that, as Figures 6 to 7 As shown, in order to better fit different patient heads, the buckle 41 is made of a deformable material, so that according to the different head sizes of different patients, the buckle 41 of the arc-shaped clamp 212 can be better engaged in the corresponding slot 42, thereby making the arc-shaped clamp 212 and the oblique clamp 222 fit the patient's head better, thus better preventing the patient's head from shaking.
[0033] It should be known that, as Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the oblique clamp 222 has anti-pressure holes on its side, so that when the oblique clamp 222 is close to the sides of the patient's head, the patient's ears can protrude from the anti-pressure holes, which helps to prevent the patient's ears from being squeezed during fixation; the two oblique clamps 222 are in an inverted V-shape, so that the oblique clamps 222 fit better with the patient's side face when clamping and fixing, so that the patient's head is fully covered, and thus the patient's head is better fixed.
[0034] It should be noted that the curved clamp 212 and the two oblique clamps 222 are covered with soft padding, which provides better protection when in contact with the patient's head and face, reduces discomfort when the patient's head is fixed, and improves the patient's comfort during fixation.
[0035] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the placement unit 11 includes a base plate 111, a middle plate 112, and multiple airbags. The base plate 111 is installed on the bed frame 1, and the middle plate 112 is positioned above the base plate 111. Multiple layers of airbags are provided between the base plate 111 and the middle plate 112. Airbags are also laid on the upper end of the middle plate 112, which makes it easier for the patient to lie more comfortably on the placement unit 11 and improves the patient's medical experience.
[0036] In this embodiment, as Figure 1 and Figure 3 As shown, it should be understood that in order to better stabilize the placement part 11, the sides of the base plate 111 and the middle plate 112 are connected to the sides of the fixing column 2, so that the placement part 11 is not easy to shake. At the same time, in order to better fit the patient's head, the middle plate 112 and multiple airbags are arranged in a U-shape, so as to better fit the patient's head and give the patient a more comfortable lying position.
[0037] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, it is understandable that in order to better and more stably fix the tubing and prevent the ventilator tubing from being pulled or displaced during operation, thereby affecting the patient's treatment, a connecting rod 23 is rotatably provided on the side of the moving block 211, and a fixing component 24 is provided on the side of the connecting rod 23. The fixing component 24 is used to clamp and fix the tubing, thereby preventing the tubing from being accidentally pulled or displaced by medical staff during operation.
[0038] In this embodiment, as Figure 1 , Figure 2 and Figure 5As shown, the fixing component 24 includes a fixing frame 241 and a fixing block 242. The fixing frame 241 is installed on the side of the connecting rod 23, and the fixing block 242 is installed on the side of the fixing frame 241 by a spring elastic limit. A pull rod extending to the outside of the fixing frame 241 is provided on one side of the fixing block 242, and an arc-shaped rubber block is provided on the side of the fixing frame 241 and the side of the fixing block 242 near which the rubber block is provided is also provided with an arc-shaped rubber block. When clamping and fixing the pipeline, the pull rod can be pulled elastically. Pulling the pull rod can cause the side of the fixing block 242 to separate from the side of the fixing frame 241. At this time, the pipeline can be placed in the open clamping area. When the pull rod is released, the elastic return of the pull rod by the spring can cause the side of the fixing block 242 to move closer to the side of the fixing frame 241, thereby clamping and fixing the pipeline in the clamping area. The operation is simple and convenient, safe and reliable, and highly practical.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
