Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, in particular to a skull bone trough shaping and comparison tool. Background Art

[0002] In modern neurosurgery, the placement of neuromodulatory implants requires the creation of a "bone socket" in the patient's skull. To ensure the socket is appropriately sized and matches the implant, clinicians typically use a steel ruler, a sterile marker, and the implant itself to compare its position and size. However, existing methods for creating a bone socket present several challenges. First, this method relies heavily on the clinician's skill and experience, increasing the complexity and difficulty of the procedure. Second, existing tools have practical limitations, requiring the surgeon to precisely measure and mark within the limited surgical field of view and operating space, requiring a high level of technical skill. Furthermore, due to the numerous variables involved in the surgical process, the position and size of the created bone socket are difficult to fully control, potentially resulting in an incomplete fit with the implant, compromising surgical outcomes. Finally, this method can cause greater damage to the patient or the implant, increasing the risk of postoperative complications. To address these issues, future surgical tools and techniques may require greater intelligence and precision, such as using 3D printing to prefabricate a bone socket template tailored to the patient's anatomy, or utilizing robotic-assisted surgical systems to enhance precision and stability. This could reduce surgical difficulty, minimize the risk of injury, and improve surgical success rates. Summary of the Invention
