[0024] It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0025] Embodiment, please refer to Figures 1-4 The hysteroscopic intrauterine pressure detector comprises a main pipeline 1, a connecting pipe 101 is arranged on the main pipeline 1, a hydraulic sensor 2 is connected to the connecting pipe 101, and the hydraulic sensor 2 is used for monitoring the pressure in the uterine cavity. Real-time monitoring can capture instantaneous fluctuations in pressure, reduce uterine tissue damage caused by unperceived sudden pressure rise and fall, provide a scientific basis for surgical operation, help medical personnel adjust the water supply speed and flow according to the pressure change, ensure clear surgical field, and maximize the risk of uterine overexpansion, improve the safety and controllability of the operation.

[0026] Further, a threaded port 102 is arranged at the inner wall of the end of the connecting pipe 101 away from the main pipeline 1, and the threaded port 102 is threadedly connected between the hydraulic sensor 2. The threaded connection mode provides multiple advantages for the assembly of the hydraulic sensor 2 and the connecting pipe 101, significantly improves the practicability and maintenance efficiency of the equipment. From the installation point of view, the threaded structure has a self-positioning function, which can ensure the coaxiality of the hydraulic sensor 2 and the connecting pipe 101, and avoid pressure detection errors caused by installation deviation. Medical personnel can quickly disassemble the hydraulic sensor 2, and disinfect, calibrate or replace the hydraulic sensor 2 before and after the operation.

[0027] Further, a sealing ring is arranged at the connection between the hydraulic sensor 2 and the connecting pipe 101. The addition of the sealing ring improves the sealing efficiency of the connection, and provides a guarantee for the accuracy of pressure detection. The sealing ring fills the gap between the threads to form a closed pressure transmission environment, ensures that the pressure sensed by the hydraulic sensor 2 is consistent with the actual pressure in the uterine cavity, and improves the detection precision.

[0028] Further, the sealing ring is made of medical silicone rubber and has an O-shaped cross section. The medical silicone rubber has undergone strict biocompatibility testing and has no toxicity and no sensitization. When it comes into contact with human tissues or body fluids, it will not produce adverse reactions, and meets the safety standards of medical devices.

[0032] Further, the controller 3 is provided with a buzzer alarm, and the shell of the controller 3 is provided with a sound hole 303 corresponding to the position of the buzzer alarm; when it is detected that the pressure value exceeds a preset threshold value (which can be adjusted through the adjusting button of the controller 3), the buzzer alarm emits continuous buzzing to prompt; the buzzer alarm builds an active early warning mechanism for pressure abnormality; compared with simply relying on manual observation of the display screen 301, the sound alarm has stronger instantaneity and warning property, and can attract the attention of medical staff at the first time when the pressure exceeds the safe range.

[0033] Further, the controller 3 is integrated with a wireless communication module, and the wireless communication module is Bluetooth or Wi-Fi, which can be connected with external terminals such as computers and tablet computers, supports real-time synchronization and remote viewing of pressure data; the wireless communication module supports real-time transmission of pressure data, alarm threshold and device state information, and is compatible with IEEE 802.11b / g / n Wi-Fi or Bluetooth 5.0 and above protocols, to ensure interconnection and intercommunication with mainstream medical terminal devices.

[0034] Further, the main pipeline 1 is made of medical-grade polytetrafluoroethylene, and the length is 20-40 cm; the polytetrafluoroethylene has excellent chemical inertness, does not react with human tissues, blood or disinfectant, and has a smooth surface and is not easy to breed bacteria, which meets the sterile requirement of medical devices.
