[0002] Stereotactic brain surgery differs from conventional craniotomy in that it is minimally invasive and precise. Its main applications include movement disorders, epilepsy, pain management, brain biopsy, and cerebral hemorrhage. The most common method for performing stereotactic surgery is a stereotactic head frame, which allows for highly precise targeting of brain nuclei or locations by setting the coordinates of target points. This is extremely helpful for precise neurosurgical treatment of diseases.

[0003] For example, Chinese utility model patent documents CN221331487U and CN215839528U disclose a stereotactic head frame, including a base assembly and four supports. These four supports require screws for installation and are fixed to the skull. After surgery, the screws come into contact with the patient's blood, and blood enters and remains on the threaded holes when the screws are tightened, making cleaning difficult. The threads on the supports are prone to wear and stripping after repeated use, and removing the screws is also inconvenient. Summary of the Invention

[0020] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1 This embodiment provides a support frame for a stereoscopic head unit that is easy to assemble and disassemble, as shown in Figures 1-5, including: The bracket body 1 has mounting holes 121 formed thereon; Screw 2 includes a tip 21 and a threaded end 22, the surface of which has external threads; The assembly 3 is installed in the mounting hole 121 by means of a snap fastener 33. Pressing the snap fastener 33 allows the assembly 3 to be removed from the mounting hole 121. A screw hole 30 is provided for the screw 2 to pass through. The screw hole 30 has an internal thread that mates with the external thread of the screw 2.

[0022] The easily detachable stereotactic head frame of this embodiment has an internal thread on the assembly 3. When the patient's blood enters the internal thread along the external thread, it also resides on the assembly 3. Pressing the latch 33 allows the assembly 3, along with the screw 2, to be easily removed from the frame body 1. The assembly 3 and screw 2 can be discarded as disposable items. If not discarded, they are easy to clean after removal, effectively preventing cross-infection. Furthermore, if the internal thread on the assembly 3 becomes worn, it can be easily replaced directly without replacing the entire frame.

[0023] Furthermore, the support body 1 includes a vertical section 11 and an inclined section 12, with the mounting hole 121 formed on the inclined section 12. The vertical section 11 has a fixing hole 111 for fixing the support body 1 to the base assembly using a fastener; the fixing method can be seen in Figure 3 of CN215839528U. The inclined section 12 causes the support body 1 to taper inward at its highest point, matching the shape of the human skull.

[0024] Furthermore, the assembly 3 includes a cylindrical body 31, protrusions 32 on both sides of the cylindrical body 31, and latches 33 on the protrusions 32. Each latch 33 includes a lever 331 and a locking block 332 on the lever 331. The screw hole 30 is formed in the middle of the cylindrical body 31. The protrusions 32 prevent the assembly 3 from rotating when the screw 2 is tightened.

[0025] Furthermore, there are two latches 33, arranged along the height direction on both sides of the cylindrical body 31, with the upper one being the first latch and the lower one being the second latch. This arrangement along the height direction allows the mounting holes 121 to also be opened along the height direction, reducing the width of the bracket body 1, and also facilitating hand operation.

[0026] Furthermore, the mounting hole 121 includes a round hole 1211 for the screw 2 to pass through, a side hole 1212 for accommodating the protrusion 32 and the paddle 331, and a slot 1213 for the locking block 332 to extend into the side wall of the side hole 1212.

[0027] Furthermore, an internal hexagonal hole is provided on the end face of the threaded end 22. Other screw holes that match the screwdriver, such as Phillips head, can also be provided depending on the actual situation.

[0028] Furthermore, the surface of the support body 1 is formed with a plurality of equally spaced transverse grooves 10. The transverse grooves 10 serve a positioning function, and by adjusting the relative position of the grooves 10 with the base assembly, the multiple support bodies 1 on the base assembly can maintain a uniform height.

[0029] Example 2 This embodiment provides a stereoscopic headgear, including a base assembly and several stereoscopic headgear supports as described in Embodiment 1, mounted on the base assembly.

[0030] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
