Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to a management system for operating room laparoscopic instrument atlases. Background Art

[0002] The current management of laparoscopic instruments in operating rooms mainly relies on simple labels and the experience memory of medical staff. The three-dimensional structural features and key points of operation of the instruments cannot be intuitively displayed through traditional labels. The efficiency of the operation is often affected by the delay in instrument recognition during the operation, and highly similar instruments are prone to confusion in operation due to the lack of differentiated warning mechanisms. The existing electronic label system can only record basic inventory information. It is impossible to associate dynamic operation diagrams and energy equipment connection instructions, and it is difficult to achieve real-time risk matching of contraindications with patient medical records. As a result, the preoperative instrument configuration preparation is time-consuming and lengthy, and there is a risk of misuse and tissue damage during the operation. At the same time, the training of new personnel is highly dependent on the explanation of physical instruments and lacks a standardized diagram guidance system. The present invention needs to solve how to achieve enhanced labeling of key instrument features, real-time warning of contraindications and traceability of the entire operation process through quickly identifiable three-dimensional dynamic identification cards, thereby improving the efficiency of surgical instrument management and operational safety. Summary of the Invention

[0003] The present application provides a management system for operating room laparoscopic instrument atlases, which overcomes the systemic defects of traditional operating room laparoscopic instrument management, such as low efficiency of intraoperative instrument identification, inability to intuitively obtain three-dimensional operation characteristics, lack of real-time linkage alarm mechanism for contraindications, and difficulty in accurately tracing the operation process, resulting in the reliance on manual memory and simple labels. It eliminates safety hazards caused by instrument confusion or operational errors in complex surgical environments, and builds a complete quality control closed loop from instrument identification, risk blocking to operation traceability.

[0004] To achieve the above objectives, the present application discloses the following technical solutions:

[0029] Furthermore, the dual-frequency RFID chip includes:

[0030] Highly anti-fouling encapsulation layer, maintaining communication reliability in blood-contaminated environments;

[0031] Dynamic data compression unit to optimize the storage structure of 3D models;

[0033] Furthermore, the operation tracing unit includes:

[0034] Zero-knowledge proof encryptor to generate tamper-proof operation hashes;

[0035] Blockchain evidence storage interface, connecting to the medical data chain;

[0041] Furthermore, the hot zone enhancement unit performs:

[0042] Surgical field coordinate conversion algorithm, mapping the instrument coordinate system to the surgical field;

[0043] Bleeding simulation prediction module, which calculates the risk of mis-cutting based on tissue characteristics;

[0044] The coordinate conversion algorithm provides a spatial anchor point for the AR projection module, and the bleeding simulation result is superimposed on the dangerous area in the form of a semi-transparent red light cover.

[0045] Furthermore, the blockchain evidence storage interface executes:

[0046] Equipment operation time lock, binding the equipment usage period to the blockchain;

[0047] Cross-institutional verification gateway supports external hospitals to access stored evidence;

[0048] The operation period data recorded by the time lock encryption is used to provide a legal-level evidence chain for medical disputes through the verification gateway.

[0049] Through the above technical solution, a management system for operating room laparoscopic instrument atlases, through the synergy of three-dimensional dynamic landmark cards and central control servers, completely eliminates the operational delays and misuse risks caused by instrument recognition lag and human memory bias in traditional surgery, and realizes the instant use of instrument three-dimensional atlases, real-time matching and warning of contraindications, and traceability of the entire operation process, significantly improving surgical safety and management efficiency; the holographic interactive terminal combines spatial coordinate mapping algorithms and force feedback mechanisms to provide surgeons with intuitive operational guidance and physically block operational errors. At the same time, based on the blockchain's encrypted evidence storage mechanism, it builds an unalterable operational responsibility chain, systematically preventing medical risks from the source and strengthening the quality management closed loop.

[0097] Example: Prevention and control of misuse of electrocoagulation hook during cholecystectomy

[0098] During the preoperative preparation phase, the central control server loads a keyword database of contraindications for pacemaker patients. When the surgeon, holding a monopolar electrocoagulation hook attached to a 3D dynamic landmark card, enters the operating table's sensing area, the card's near-field communication module automatically broadcasts the device code DEV-EL-5A, contraindication data ["monopolar device," "pacemaker contraindications"], and the electrode tip hot zone coordinates to the central server. The server immediately retrieves the patient's electronic medical record and uses the contraindication matching engine to perform keyword intersection analysis. Upon detecting the "pacemaker" risk item, a three-level alert protocol is triggered: a power-off command is sent to the electrocoagulation hook host, forcing power outages. A red pulsing warning overlay is displayed on the operating room's main screen. Simultaneously, the AR glasses are activated to superimpose a pulsing red light marker on the electrode tip hot zone within the surgical field. Force feedback gloves simultaneously detect the gripping posture, triggering an 8Hz high-frequency vibration to force the surgeon to release their grip. A voice alarm system announces, "Contraindicated device! Stop operation immediately!" The operator immediately ceases operation.

[0099] The system automatically switches to a safe alternative within a sub-second response time. An AR interface projects a 3D animation of the insulated separating forceps operation, dynamically demonstrating the 90° rotation of the forceps and the tissue separation path. The operation traceability unit records the entire process, including event timestamps, operator ID, and blocking measures. A zero-knowledge proof engine generates a structured log, which is converted into a blockchain hash value (0x7d3f...a9c1) and stored in a medical alliance chain evidence storage node. This evidence includes the tactile feedback intensity curve and the precise time the device powered off, forming an unalterable chain of legal electronic evidence.

[0100] This embodiment completely eliminates the risk of instrument misuse due to human negligence in traditional surgery through closed-loop control of near-field recognition, multimodal blocking and real-time guidance: three-dimensional landmark cards achieve millisecond-level automatic matching of contraindications, which increases the efficiency of instrument safety identification tenfold; a multi-level physical blocking mechanism, equipment power off and tactile forced intervention ensure 100% interception of illegal operations; AR dynamic guidance seamlessly connects alternative instrument operation paths to ensure surgical continuity; blockchain evidence storage fully records the operator's behavior trajectory, provides legal-level technical endorsement for medical quality traceability, and systematically reconstructs surgical safety management standards.
