Problems solved by technology

[0004] Aiming at the defects and problems existing in the existing head fixation devices, the present invention provides an easy-to-adjust head fixation for pediatric surgery. The unique structure of the device not only effectively solves the problem that the shape of the splint cannot be changed according to the shape of the child's head This leads to the problem of poor clamping and fixing effect, and it also effectively solves the problem that the head needs to be loosened and manually moved to adjust the angle.

Embodiment 1

[0038] This embodiment provides a conveniently adjustable head fixation device for pediatric surgery, such as Figure 1-10 As shown, it includes a lifting base 1, the lifting base 1 is connected with a controller, and also includes a device frame 2, a head collar 3, a connecting mechanism 4, a driving mechanism 5 and a head fixing device, and the device frame 2 is fixed on the lifting base. On the seat 1, the height of the device frame 2 can be adjusted by controlling the lifting base 1 by the controller. There are many types of the lifting base 1, for example: the existing manual lifting base or the electric lifting base.

[0039] There is a head placement area in the device frame, and the head collar is installed in the head placement area through the connecting mechanism, and is connected with the driving mechanism in transmission. The driving mechanism can be driven by the controller to rotate the head sleeve around its axis, and deadlock, specifically:

[0040] Such as ...

Embodiment 2

[0053] The difference between embodiment 2 and embodiment 3 is that the connecting shaft is rotatably connected with the supporting column on the connected side through a bearing.

[0054] Such as Figure 11 As shown, there are symmetrical shaft holes on the support columns on the left and right sides of the head collar, and the other single pass bearing of the connection column is matched and installed in the shaft hole of the support column, and the shaft hole of the support column is coaxial with the connection column. , the connecting column on the left side of the head collar extends out of the supporting column, and is connected with an elevation angle adjustment mechanism. The elevation angle adjustment mechanism is connected with the controller, and the elevation angle adjustment mechanism is controlled by the controller to drive the head cover around the left and right connecting columns Rotate at a fixed angle, specifically:

[0055] The elevation angle adjustment m...

Embodiment 3

[0057] The difference between embodiment 3 and embodiment 2 is that the mounting base is slidably installed on the collar body and can slide along the circumference of the collar body.

[0058] Such as Figure 12-14 As shown, the mounting seat is slidably installed on the collar body, and can slide along the circumference of the collar body, and there is a locking part on the mounting seat, which is used to fix the position of the sliding seat. The head sleeve of the head is replaced with a forehead pressing mechanism, which includes a sliding seat 91 and a spring rod 92. The structure of the sliding seat 91 is the same as that of the mounting seat 721, and both of them are slidably installed on the collar body. Lockdown components, specifically:

[0059] Such as Figure 14 As shown, ring-shaped track grooves 312 are symmetrically opened on the ring surfaces of the front and rear ends of the collar body 31, and the mounting seat 721 includes a mounting seat body 7211 arrange...

Abstract

The invention discloses a pediatric surgery head fixing device convenient to adjust, the pediatric surgery head fixing device comprises a lifting base, the lifting base is connected with a controller, the pediatric surgery head fixing device further comprises a device frame, a head lantern ring, a connecting mechanism, a driving mechanism and a head fixing device, the device frame is fixed on the lifting base, and a head placing area is arranged in the device frame; the head sleeve ring is installed in the head placing area through a connecting mechanism and is in transmission connection with the driving mechanism, and the driving mechanism is controlled by the controller to drive the head sleeve to rotate around the axis of the head sleeve and be locked; the device is unique in structure, the problem that the clamping and fixing effect is poor due to the fact that the shape of a clamping plate cannot be changed according to the shape of the head of a child is effectively solved, and the problem that angle adjustment can be achieved only by loosening the head and manually moving the head during angle adjustment is also effectively solved.

Description

technical field [0001] The invention belongs to the technical field of pediatric surgical instruments, and in particular relates to an easily adjustable head fixation for pediatric surgery. Background technique [0002] Head immobilizer is a common medical equipment. During the operation, children must keep their head posture unchanged for a certain period of time. If it shakes, it will have a certain impact on the effect of the operation. Most of them are under normal anesthesia. Perform surgery, but anesthesia cannot completely solve the problem. When the patient is in a coma or unconscious state and cannot actively cooperate with the operation, a head immobilizer is needed to ensure that the child’s head posture is kept fixed during the operation. . [0003] The structure of the existing head immobilization device is too simple, and only the splint is used to fix the head. However, since the head sizes of children of different ages and physiques are not the same, the sha...
