The connecting seat's tenon connects to the groove of the surgical guide. Loosening the locking bolts and adjusting the angle by rotating the rod relative to the connecting seat causes the second screw to rotate, thus moving the clamping block. The clamping block clamps and fixes the side wings of the surgical guide. A transparent acrylic plate on the installation plate facilitates student understanding of the component's movement trajectory. The clamping block is magnetically connected to a magnetic mounting bracket for easy assembly and disassembly, allowing practice of component combination logic. A flexible thin-film pressure sensor on the clamping block, along with a microcontroller and a low-power Bluetooth module, transmits signals to the teaching tablet, enabling students to understand the clamping force. This transforms the device from a clinical tool into a teaching equipment, providing auxiliary teaching for craniocerebral surgery positioning.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical auxiliary equipment technology, specifically an auxiliary teaching device for positioning in craniocerebral surgery. Background Technology
[0002] By locating the hematoma using preoperative CT scans, the approximate location of the hematoma on the body surface can be estimated, and the puncture path, puncture angle, and puncture depth can be calculated. Based on the three-dimensional morphology of the forehead or auricle, a surgical guide for craniocerebral surgery can be fabricated, which can provide relatively accurate positioning and navigation support for deep brain surgery and meet the positioning requirements of cerebral hemorrhage surgery. Sufficient teaching equipment is required before craniocerebral surgery positioning.
[0003] A search of Chinese patent CN219461439U reveals a surgical guide auxiliary positioning device for craniocerebral surgery. The device utilizes a second screw, connecting seat, and rotating rod to facilitate positioning of the surgical guide. The first screw and clamping block hold the surgical guide in place, allowing for external fixation and preventing rejection or allergic reactions. This expands the device's applicability and improves its practicality. The mounting plate, connecting plate, and connecting bolts 22 facilitate installation on the operating table. Furthermore, the device can be repeatedly sterilized and reused, reducing waste of medical resources and lowering surgical costs.
[0004] Based on the above search and existing technology, it was found that: the mechanical structure of the internal positioning component is obscured, making it inconvenient for students to observe the adjustment principle; the disassembly and assembly of structures such as clamps are cumbersome, making it inconvenient to practice the logic of component disassembly and assembly; and the clamping force cannot be understood in real time. Teaching simulations are prone to positioning deviations, which affects the teaching of craniocerebral surgery positioning. Utility Model Content

A connecting seat is threadedly connected to the outer wall of the first screw. The connecting seat is slidably connected to the outer wall of the limit rod. A cavity is provided inside the mounting plate. A transparent acrylic plate is fixedly connected to one outer wall of the cavity. A second screw is threadedly connected to both outer walls of the mounting plate. A magnetic mounting frame is fixedly connected to one outer wall of the second screw. A clamping block is provided on the inner wall of the magnetic mounting frame. A flexible thin-film pressure sensor is installed on the inner wall of the clamping block. A low-power Bluetooth module is provided on one outer wall of the magnetic mounting frame. A teaching tablet is installed on the outer wall of the transparent acrylic plate.
[0009] Preferably, the flexible thin-film pressure sensor and the low-power Bluetooth module are electrically connected, and the magnetic mounting bracket is adapted to the size of the clamping block.
[0010] Preferably, a locking bolt is connected through one end of the connecting seat, a rotating rod is sleeved on the outside of the locking bolt, and a tenon is connected to the bottom end of the rotating rod. The tenon is adapted to the groove size of the surgical guide plate.
[0011] Preferably, the outer wall of the limiting rod is provided with scale markings, and the bottom outer wall of the mounting plate is fixedly connected to a connecting plate.
[0012] Preferably, the bottom outer wall of the connecting plate is connected with a connecting bolt by a thread, and the connecting bolt is adapted to the position of the connecting plate.
