[0002] The first condition for pediatric puncture surgery is good head fixation. Children have much less self-control than adults. If the child's head is not firmly fixed, it may affect the normal operation and even cause great danger to the child. At present, in clinical practice, for medical instruments to fix the patient's head during surgery, the existing fixing devices usually fix it directly in a way similar to clamping the face, which easily only clamps the widest part of the face and cannot fix other parts.

[0003] To this end, relevant technicians have proposed a fixing device as shown in CN211985715U, which fixes the patient's head by adjusting the splints on the top, sides and bottom of the patient. However, the top and side adjustments of the device need to be operated separately, and it is difficult to adjust the positions of the top and side splints at the same time. Summary of the invention

DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0022] Please also read Figure 1 and Figure 2 , this embodiment provides an auxiliary puncture device, including a housing 1, a transmission assembly 2, a lateral clamping assembly 3, a downward pressing fixing mechanism 4 and a lifting assembly 5;

[0023] The transmission assembly 2 is rotatably disposed in the shell 1, and the lateral clamping assembly 3 is slidably disposed on the shell 1. The sliding of the transmission assembly 2 can drive the two sides to move closer to or away from the clamping assembly 3; it should be understood that the shell 1 is a box with an opening, and the patient lies in the box when in use.

[0024] The lower fixing mechanism is liftably disposed on the shell 1. The descent of the lower fixing mechanism can cause the transmission assembly 2 to rotate, and the lower fixing mechanism can maintain the height after the descent; specifically, the descent of the lower fixing mechanism can cause the two side clamping assemblies 3 to approach, and the ascent of the lower fixing mechanism can cause the two side clamping assemblies 3 to move away from each other.

[0025] The lifting assembly 5 is movably disposed on the bottom surface of the housing 1. It should be understood that when the patient lies on the lifting assembly 5, the lifting assembly 5 can maintain the height after the lifting.

[0026] It is worth mentioning that the housing 1 is a rectangular frame.

[0027] In the present application, after the patient's head is placed at the desired angle, the two sides can be moved closer to the clamping assembly 3 by pressing down the fixing mechanism 4, so that the operator can complete the lateral and vertical fixation of the patient's head through a single operation, thereby making the patient's head meet the requirements of the puncture position, angle, etc.

[0028] In other embodiments, the transmission assembly 2 includes a rotating shaft 21, a first gear 22, and a second gear 23; the rotating shaft 21 is rotatably connected to the housing 1, and the first gear 22 and the second gear 23 are coaxially fixed on the rotating shaft 21, respectively. The rotation of the first gear 22 can simultaneously drive both sides to approach or move away from the clamping assembly 3, and the lifting and lowering of the pressing and fixing mechanism 4 can drive the second gear 23 to rotate. Specifically, the lowering of the pressing and fixing mechanism 4 can drive the rotation of the second gear 23 and thus make both sides approach the clamping assembly 3.

[0029] In other embodiments, the lateral clamping assembly 3 includes a sliding rod 31, a lateral rack 32, a lateral connecting rod 33 and a lateral clamping plate 34; the sliding rod 31 is slidably connected to the housing 1, the lateral rack 32 is arranged on the sliding rod 31, and is connected to the lateral clamping plate 34 through the lateral connecting rod 33, and the lateral rack 32 is meshed with the first gear 22. It should be understood that the lateral racks 32 of the two side clamping assemblies 3 are respectively arranged on both sides of the first gear 22.

[0030] In other schemes, the downward pressing fixing mechanism 4 includes a downward pressing driving screw 41, a ball bearing 42, a downward pressing connecting assembly 43 and a downward pressing plate 44; the downward pressing driving screw 41 is screwed on the shell 1, and is connected to the downward pressing connecting assembly 43 through the ball bearing 42. The lifting and lowering of the downward pressing connecting assembly 43 can drive the first gear 22 to rotate, and the downward pressing plate 44 is arranged on the downward pressing connecting assembly 43.

[0031] In other schemes, the pressing connection assembly 43 includes a pressing connection frame 431, a pressing rack 432, an elastic connecting component 433 and an adjusting stud 434; the pressing connection frame 431 is connected to the ball bearing 42, the pressing rack 432 is slidably disposed in the pressing connection frame 431, and is connected to the pressing connection frame 431 through the elastic connecting component 433; the pressing rack 432 can engage with the second gear 23, the adjusting stud 434 is screwed on the pressing connection frame 431, and changing the position of the adjusting stud 434 can change the meshing state of the pressing rack 432 and the second gear 23, and the bottom of the pressing connection frame 431 is connected to the pressing plate 44. Specifically, the top of the pressing rack 432 is provided with an inclined surface, and the adjusting stud 434 can be pressed downward to squeeze the inclined surface of the pressing rack 432, so that the pressing rack 432 and the second gear 23 are meshed, and the adjusting stud 434 can move upward to make the pressing rack 432 move away from the second gear 23 and release its meshing state under the drive of the elastic connecting component 433. By adjusting the stud 434 to change the meshing state of the pressing rack 432 and the second gear 23, it is possible to change the pressing state of the top alone when the side of the patient's head is clamped and the top is not fixed, and the pressing rack 432 is meshed again after reaching the required position, and the two sides and the top are moved toward the patient's head for fixing again. It should also be understood that the adjusting stud 434 passes through the housing 1. Preferably, the pressing connection frame 431 is connected to the housing 1 through a lifting slider, and the lifting slider is slidably connected to the housing 1 in a lifting manner.
