This invention provides a post-anesthesia follow-up monitoring system for monitoring and early warning of post-brain surgery conditions. Specifically, it includes: a patient brain surgery information synchronization module, a follow-up monitoring task generation module, a complication early warning handling module, a quality control and data management module, a standardized electronic form module, a mobile follow-up monitoring module, a discharge remote follow-up monitoring module, and a system management module. The modules are divided into main modules and auxiliary modules. Each module in the main modules interacts bidirectionally with three or more other modules and performs core functions such as data processing, optimization, and parameter calculation. The auxiliary modules provide auxiliary functions such as data acquisition, task execution, and access control. This invention automates the follow-up monitoring process, significantly reducing post-operative PONV, respiratory depression, and nerve damage, and achieves full retention of perioperative anesthesia data, supporting departmental quality control, grade review, research projects, and thesis data.

Signals of a brain operation area are collected in real time through the multi-channel sensor array, synchronous collection of the data collection module and dynamic analysis of the data processing module are combined, and the survival state, the distribution condition and the function change of transplanted endothelial progenitor cells can be monitored in real time.

The application discloses a brain operation dilator which comprises a main body conduit and a driving mechanism arranged on the side of the main body conduit; the main body conduit comprises a shell and a plurality of supporting rods, the middle part of each supporting rod is rotationally connected with the shell, the two ends of each supporting rod at the rotation point are respectively a dilating end and an adjusting end, the same elastic tube is sleeved on the positions of the dilating ends of the plurality of supporting rods, the end of the shell away from the elastic tube is provided with a rotating disc, a plurality of arc-shaped holes are penetrated through one side of the rotating disc, the end of each supporting rod penetrating through the adjusting hole is matched with the arc-shaped hole, and the distances from the two ends of each arc-shaped hole to the axis of the rotating disc are different; when the driving mechanism drives the rotating disc to rotate, the rotating disc drives the adjusting end of the plurality of supporting rods to change the radial displacement, so that the dilating end of the plurality of supporting rods swings to drive the elastic tube to dilate. The application has the advantages and effects that the safety and accuracy in the brain operation process can be improved, and the brain operation dilator is suitable for the micro-operation technology of neurosurgery.

The application relates to the field of neurosurgical medical equipment and discloses a brain operation auxiliary treatment device for neurosurgery, which comprises a fixing base, a gear groove and a ratchet groove are arranged in the fixing base, a connecting block is slidably connected in the fixing base, a locking cavity is arranged in the connecting block, a clamping assembly is slidably connected to the top end of the connecting block, a locking assembly is arranged in the locking cavity, the locking assembly comprises a ratchet pawl, one end of the ratchet pawl is in sliding contact with a limiting plate, the limiting plate is in abutment with a limiting cam on one side, and the limiting cam is rotationally connected to an adjusting block. In the application, the fixing base is divided into the gear groove and the ratchet groove, the connecting block bears the clamping assembly and is internally provided with the locking cavity, the structure realizes clear function division, and the transmission and the locking mechanism are prevented from interfering. In cooperation with the ratchet pawl, the limiting plate, a return spring and a reverse ratchet, the first return spring always pushes the limiting plate to abut against the limiting cam, so that the locking can be instantly responded.
