Description

Technical Field

[0001] This utility model belongs to the field of head fixation technology, and in particular relates to a neurosurgical head fixation frame. Background Technology

[0002] A neurosurgical head fixation device is a medical device used to stabilize the position and angle of a patient's head during neurosurgery. Its main function is to keep the patient's head fixed during surgery, avoiding any unnecessary movement, in order to ensure precise surgical operation and safety. Head fixation devices are commonly used in treatments that require precise positioning, such as brain surgery, craniocerebral trauma, and stereotactic radiotherapy.

[0003] The existing utility model with authorization announcement number CN221751281U discloses a neurosurgical head positioning device, including a head frame fixing arm and a movable arm. The head frame fixing arm and the movable arm are slidably connected. Both the head frame fixing arm and the movable arm are equipped with head clamps to fix the patient's head. The head frame fixing arm is equipped with a locking seat for locking the movable arm. The bottom side of the head frame fixing arm is equipped with a mounting bracket.

[0004] The above technical solution, through the setting of the support mechanism, rotates the flipping frame to drive the support frame to rotate, so that it rotates above the head frame fixing arm, thereby supporting the patient's neck. This ensures both patient comfort and stable head support. However, although the above technical solution can play a role in assisting in fixing the patient's head during use, the fixing frame cannot be quickly disassembled for replacement and disinfection after use. As a result, bacteria and viruses may remain on the surface of the fixing frame after use, which greatly affects the use by subsequent patients and leads to a problem of poor practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 In one embodiment of this utility model, a neurosurgical head fixation frame is provided, including a base plate 1; a fixing plate 2 is provided above the base plate 1, and two movable frames 9 are slidably connected to the inner wall of the fixing plate 2. Four support legs 3 are fixedly connected to the bottom surface of the base plate 1, and a base 4 is fixedly connected to the bottom end of each support leg 3. The support legs 3 can support the fixation frame to a certain height, avoid direct contact with the placement surface, and prevent the bottom surface from getting damp or contaminated with dust and other impurities. The base 4 at the bottom end of each support leg 3 further increases the contact area with the placement surface, making the fixation frame more stable during use and less prone to tipping over.

[0023] Furthermore, each movable frame 9 has a fixedly connected limit seat 12 on its inner bottom wall, and each limit seat 12 has a movable block 13 above it. The bottom surface of the fixed plate 2 is fixedly connected to three connecting blocks 5, and the outer surface of each connecting block 5 is slidably connected to a limit frame 6. The bottom surface of each limit frame 6 is fixedly connected to the upper surface of the base plate 1. The sliding connection structure between the connecting block 5 and the limit frame 6 allows the fixed plate 2 to be adjusted relative to the base plate 1 within a certain range. The bottom surface of the limit frame 6 is fixedly connected to the upper surface of the base plate 1. This structure can limit the movement of the fixed plate 2, ensuring that the movement of the fixed plate 2 in the vertical direction has a certain guiding property, and preventing unnecessary deviation or shaking.

[0024] Each movable block 13 has a connecting seat 18 fixedly connected to its bottom surface. The outer surface of each connecting seat 18 is in contact with the inner wall of the limiting seat 12. One of the connecting blocks 5 has an electric telescopic rod 11 fixedly connected to its bottom surface. The bottom end of the electric telescopic rod 11 is fixedly connected to the inner bottom wall of one of the limiting frames 6. Through the telescopic movement of the electric telescopic rod 11, the height of the fixation plate 2 relative to the base plate 1 can be precisely adjusted. In neurosurgery, different patients may have different needs. The electric telescopic rod 11 can quickly and accurately adjust the fixation plate 2 to a suitable height, thereby adjusting the height of the entire head fixation frame to adapt to different surgical operation requirements.

[0025] Each movable block 13 has a fixed clamping ring 17 fixedly connected to its outer surface, and each movable frame 9 has a limit plate 15 slidably connected to its inner wall. The inner walls of the two movable frames 9 are threadedly connected to a bidirectional threaded rod 10. The outer surface of the bidirectional threaded rod 10 is rotatably connected to the inner wall of the fixed plate 2. The rotatable connection between the bidirectional threaded rod 10 and the inner wall of the fixed plate 2 ensures its stability during rotation. By rotating the bidirectional threaded rod 10, the two movable frames 9 can move towards each other or away from each other within the fixed plate 2. This structural design allows the spacing of the fixed clamping rings 17 to be easily adjusted to accommodate different patient head sizes, thereby more accurately fixing the patient's head and improving the flexibility and adaptability of the head fixation frame.

[0026] The outer surface of each limiting plate 15 is slidably connected to the inner wall of the moving block 13. Each limiting frame 6 has a reinforcing block 7 fixedly connected to both sides. The bottom surface of each reinforcing block 7 is fixedly connected to the upper surface of the base plate 1. The fixed connection between the reinforcing block 7 and the upper surface of the base plate 1 further stabilizes the position of the limiting frame 6, preventing the limiting frame 6 from deforming or shifting when subjected to external force, thereby ensuring the accuracy of the movement and fixation of the fixing plate 2 and maintaining the stability of the entire head fixing frame structure.

[0027] Two springs 16 are fixedly connected to the opposite sides of the two limiting plates 15. The opposite ends of the two sets of springs 16 are fixedly connected to the inner wall of the moving frame 9. A headrest 8 is fixedly connected to the upper surface of the fixing plate 2. A rubber pad 14 is fixedly connected to the outer surface of each fixing clamp 17. The headrest 8 on the upper surface of the fixing plate 2 provides a comfortable support for the patient's head, reducing the pressure when the patient's head is in direct contact with the fixing plate 2 and improving the patient's comfort. The rubber pad 14 on the outer surface of the fixing clamp 17 plays a role in buffering and protection. When fixing the patient's head, the rubber pad 14 can prevent the fixing clamp 17 from causing pressure damage to the patient's head. At the same time, it increases the friction with the head, making the head fixation more stable. While ensuring the head fixation effect, it also focuses on the patient's user experience.

[0028] The working principle of this utility model is as follows: In use, first, connect the power supply to the electric telescopic rod 11. The support leg 3 rests on the bottom surface of the base plate 1, and its bottom base 4 provides stable support. The headrest 8 on the fixed plate 2 provides a place for the patient's head. Then, activate the electric telescopic rod 11. The electric telescopic rod 11 can drive the connecting block 5 to move up and down, thereby driving the fixed plate 2 to move up and down to adjust to a suitable height. Afterwards, the staff can put a disposable plastic protective cover on the headrest 8 to prevent bacterial contamination. Then, when the bidirectional threaded rod 10 rotates, due to its threaded connection with the two moving frames 9, the two moving frames 9 will move relative to or away from each other. The limiting seat 12 inside the moving frame 9 has a moving block 13, which can drive the fixed clamping ring 17 to move. The fixed clamping ring 17 outside the moving block 13 is used to fix the head. The rubber pad 14 on the fixed clamping ring 17 can increase comfort, thereby making it easier to fix the patient's head for treatment. After the treatment is completed, the staff will reset the moving frame 9 and pull the limiting plate 15 outward. When the limiting plate 15 moves, it can squeeze the spring 16 until the limiting plate 15 is disengaged from the moving block 13, thereby releasing the limitation on the moving block 13 and the fixed clamping ring 17. Finally, the fixed clamping ring 17 can be removed and replaced, and the removed fixed clamping ring 17 is disinfected to facilitate the next sterile use. At the same time, the inclined design of the limiting seat 12 and the connecting seat 18 can make the two contact more tightly, avoid gaps between them, and ensure the stability of the fixed clamping component.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
