Through continuous research and design, and through repeated trial production and refinement, the applicant has finally created the present utility model, which possesses truly practical value.

[0048] Please refer to Figure 1-2The present invention provides an auxiliary fixing base for mounting a stereotactic head frame. This base is used to secure the head frame and stabilize the patient's head during installation, optimizing and enhancing device stability and operational safety during surgery. The core component of this fixing base is the base body 1, which features an ingenious design. A fixing groove 2 is meticulously carved into its top surface. This groove is meticulously customized based on the specific shape and size of the stereotactic head frame, ensuring that the instrument fits seamlessly and securely within it.

[0049] It is worth elaborating on the core innovation of this embodiment, which is that by introducing a clever combination of the base body 1 and the fixing slot 2, the shaking problem that may occur in the traditional brain stereotactic instrument during surgery has been completely overcome. The precise size and shape design of the fixing slot 2 not only achieves a tight fit and locking of the head frame of the brain stereotactic instrument, but also greatly reduces the risk of displacement caused by external factors, thereby ensuring the high stability and reliability of the instrument throughout the operation. The headrest portion is provided on the base body 1, which can provide support for the patient's head and further enhance stability and comfort. These improvements not only bring patients a more comfortable and reassuring treatment experience, but also significantly improve the accuracy and success rate of surgical operations by reducing uncertainties in the surgical process, laying a solid foundation for the optimization of medical effects.

[0050] To sum up, the auxiliary fixing base for the head frame installation of the brain stereotactic instrument provided by the present invention is not only a powerful response to the defects of the existing technology, but also an important contribution to the improvement of medical safety and surgical quality. Its far-reaching significance deserves widespread attention and praise from the industry.

[0051] Please refer again Figure 1-2 The head frame mounting auxiliary fixing base of the brain stereotactic instrument in this embodiment is more sophisticated and comprehensive, as specifically reflected in the structure of the fixing slot 2. The fixing slot 2 is not a single structure, but is composed of two or more independent but cooperating parts: a first fixing slot 21 and a second fixing slot 22. The number of first fixing slots 21 and second fixing slots 22 is unlimited.

[0052] First fixing slot 21: This slot is specifically designed for the rear frame of the stereotactic headframe. Its shape, size, and depth are precisely calculated and simulated to ensure the rear frame fits securely and securely within the headframe. This design effectively prevents any movement of the rear frame during surgery, ensuring a smooth and effective procedure.

[0053] Second fixing slot 22: Complementing the first fixing slot 21, the second fixing slot 22 specifically secures the two rear columns of the stereotactic head frame. Similarly, its design takes into account the structural characteristics and fixation requirements of the two rear columns of the head frame, ensuring that they fit tightly and securely within the slot. This design not only enhances the stability of the entire device but also further improves the precision and safety of surgical procedures.

[0054] In this embodiment, the design of the base body 1 is further optimized and enhanced. Specifically, an anti-slip pad is specially added to the bottom surface of the base body 1.

[0055] The use of anti-slip pads is primarily based on the following considerations: First, they effectively increase the friction between the base body 1 and the operating table, preventing unnecessary sliding or shifting of the equipment due to external forces during surgery. This increased stability is crucial for ensuring the accuracy and safety of surgical operations.

[0056] Secondly, the anti-slip mat also has a certain shock-absorbing effect. During surgery, the equipment may be subjected to minor collisions or vibrations from the patient's body or surgical instruments. The presence of the anti-slip mat can absorb and disperse this vibration energy, reducing potential damage to the brain stereotactic instrument and its fixed components, thereby extending the service life of the equipment.

[0057] Furthermore, the material of the anti-slip mat is typically carefully selected to ensure good wear resistance, corrosion resistance, and easy cleaning. These properties allow the mat to maintain a stable anti-slip effect over time, while also facilitating post-operative cleaning and disinfection, meeting the hygienic requirements of medical equipment.

[0058] In this embodiment, to further enhance the adaptability and protection of the head frame mounting auxiliary fixing base of the stereotactic apparatus, several innovative grooved cushioning pads are introduced. These grooved cushioning pads not only have unique structural features but also significantly enhance the performance of the apparatus in multiple aspects.

[0059] Specifically, the contours of each groove-shaped cushion are carefully designed and manufactured to ensure they perfectly match the inner wall of the fixing groove 2. This design allows the groove-shaped cushion to fit tightly within the fixing groove 2 and is not easily dislodged or shifted, thereby ensuring its stability and reliability during use.

[0060] Even more unique is that each grooved cushion has a different thickness. This differentiated design takes into account the varying size requirements of different stereotactic instruments. By selecting the appropriate grooved cushion thickness, it can be adapted to different models and specifications of stereotactic instruments. Furthermore, the detachable design facilitates quick assembly and disassembly for maintenance or replacement, improving work efficiency and convenience.

[0061] In this embodiment, two feasible design solutions are provided for the connection between the fixing groove 2 and the groove-shaped buffer pad to meet the needs of different application scenarios.

[0062] The first design:

[0063] Special engaging grooves are provided in the fixing groove 2. The position, shape, and size of these engaging grooves have been carefully designed to ensure that they precisely match the engaging blocks on the groove-shaped buffer pad. Corresponding engaging blocks are provided on the groove-shaped buffer pad. These engaging blocks can be raised structures or other shapes that can closely match the engaging grooves. When the groove-shaped buffer pad is placed in the fixing groove 2, the engaging blocks will naturally snap into the engaging grooves, thereby achieving a stable connection between the groove-shaped buffer pad and the fixing groove 2. This connection method is not only easy to operate, but also has a firm connection, which can effectively prevent the groove-shaped buffer pad from shifting or falling off during use.

[0064] The second design:

[0065] In contrast to the first solution, this solution features a snap-fit ​​block directly within the fixing slot 2, while the slotted cushion has a corresponding snap-fit ​​groove. This design also ensures a tight fit between the slotted cushion and the fixing slot 2. During installation, the user simply aligns the snap-fit ​​groove on the slotted cushion with the snap-fit ​​block within the fixing slot 2 and gently presses to complete the installation. This reverse snap-fit ​​design may make installation and removal easier in some cases, while also ensuring a secure connection.

[0066] It is understandable that both the first and second design schemes achieve a secure connection between the fixing slot 2 and the groove-shaped cushion through the ingenious combination of the snap-fit ​​slot and the snap-fit ​​block. This connection method not only enhances the overall stability of the head frame mounting auxiliary fixing base of the brain stereotactic instrument, but also improves the applicability and flexibility of the device, providing users with a more convenient and efficient user experience.

[0067] Please refer to Figure 3-4The base body 1 in this embodiment exhibits a high degree of flexibility and customizability in its structural design. Specifically, the base body 1 is cleverly divided into three independent but interrelated parts: a first part 11, a second part 12, and a third part 13. These three parts are not fixed together, but are connected in a detachable manner. This innovative design brings many advantages.

[0068] First, the detachable connection makes the base body 1 more convenient during transportation, storage, and maintenance. Users can easily disassemble the base body 1 into multiple smaller components as needed, saving space and reducing transportation costs. Furthermore, when cleaning or repair is required, specific components can be accessed without disassembling the entire base body, improving work efficiency.

[0069] Secondly, this modular design allows for adaptability and scalability of the base body 1. With the advancement of medical technology and evolving surgical needs, users may need to adjust or upgrade the base body based on their specific needs. By replacing or adding or removing different components, users can flexibly adjust the size, shape, and functionality of the base body 1 to meet diverse surgical requirements.

[0070] Finally, from a manufacturing perspective, the detachable design also helps reduce production costs. Manufacturers can flexibly adjust the production quantity and specifications of individual components based on market demand forecasts, avoiding the waste of resources caused by overproduction. Furthermore, if a component is damaged or needs to be replaced, users only need to purchase the corresponding part, rather than the entire base, reducing operating costs.

[0071] Please refer to Figure 5 The base body 1 in this embodiment has been further optimized and expanded in its structural design. Specifically, in addition to the previously mentioned first portion 11, second portion 12, and third portion 13, a new component, fourth portion 14, has been introduced. This innovative design not only enhances the structural strength and stability of the base body 1, but also provides it with greater functionality and flexibility.

[0072] At least one fourth portion 14 is cleverly disposed between the first portion 11 and the second portion 12, and at least one fourth portion 14 is cleverly disposed between the third portion 13 and the second portion 12. It is worth noting that the "at least one" mentioned here means that in actual applications, multiple fourth portions 14 can be provided as needed to further reinforce or adjust the structure of the base body 1.

[0073] The introduction of the fourth portion 14 offers multiple advantages. First, as a connector, it effectively strengthens the connection between the various parts, making the base body 1 more stable and less prone to deformation when subjected to external forces. This is crucial for ensuring the stability of the stereotactic apparatus during surgery.

[0074] Secondly, the fourth portion 14 can also be used as an adjustment element. By adjusting parameters such as its number, position, or material, the user can flexibly adjust the overall height and tilt angle of the base body 1 to accommodate different surgical requirements or patient positions. This adjustability not only improves the adaptability of the device but also provides a more convenient operating experience for the user.

[0075] Although the terms "base body," "fixing slot," and "first fixing slot" are frequently used in this application, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.

[0076] The utility model provides an auxiliary fixing base for installing a head frame of a brain stereotactic instrument, comprising a base body. By providing a fixing groove on the top surface of the base body for the head frame of the brain stereotactic instrument to be snapped in and fixed therein, and a headrest portion for supporting the patient's head, the problem of shaking when the head frame of the brain stereotactic instrument is installed causing the installed head frame to deflect and affect the surgical effect can be fundamentally solved, thereby ensuring absolute stability and safety during the operation, bringing a more comfortable treatment experience to the patient, and significantly improving the success rate of the operation and the treatment effect.

[0077] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
